Bob The Magic Custodian



Summary: Everyone knows that when you give your assets to someone else, they always keep them safe. If this is true for individuals, it is certainly true for businesses.
Custodians always tell the truth and manage funds properly. They won't have any interest in taking the assets as an exchange operator would. Auditors tell the truth and can't be misled. That's because organizations that are regulated are incapable of lying and don't make mistakes.

First, some background. Here is a summary of how custodians make us more secure:

Previously, we might give Alice our crypto assets to hold. There were risks:

But "no worries", Alice has a custodian named Bob. Bob is dressed in a nice suit. He knows some politicians. And he drives a Porsche. "So you have nothing to worry about!". And look at all the benefits we get:
See - all problems are solved! All we have to worry about now is:
It's pretty simple. Before we had to trust Alice. Now we only have to trust Alice, Bob, and all the ways in which they communicate. Just think of how much more secure we are!

"On top of that", Bob assures us, "we're using a special wallet structure". Bob shows Alice a diagram. "We've broken the balance up and store it in lots of smaller wallets. That way", he assures her, "a thief can't take it all at once". And he points to a historic case where a large sum was taken "because it was stored in a single wallet... how stupid".
"Very early on, we used to have all the crypto in one wallet", he said, "and then one Christmas a hacker came and took it all. We call him the Grinch. Now we individually wrap each crypto and stick it under a binary search tree. The Grinch has never been back since."

"As well", Bob continues, "even if someone were to get in, we've got insurance. It covers all thefts and even coercion, collusion, and misplaced keys - only subject to the policy terms and conditions." And with that, he pulls out a phone-book sized contract and slams it on the desk with a thud. "Yep", he continues, "we're paying top dollar for one of the best policies in the country!"
"Can I read it?' Alice asks. "Sure," Bob says, "just as soon as our legal team is done with it. They're almost through the first chapter." He pauses, then continues. "And can you believe that sales guy Mike? He has the same year Porsche as me. I mean, what are the odds?"

"Do you use multi-sig?", Alice asks. "Absolutely!" Bob replies. "All our engineers are fully trained in multi-sig. Whenever we want to set up a new wallet, we generate 2 separate keys in an air-gapped process and store them in this proprietary system here. Look, it even requires the biometric signature from one of our team members to initiate any withdrawal." He demonstrates by pressing his thumb into the display. "We use a third-party cloud validation API to match the thumbprint and authorize each withdrawal. The keys are also backed up daily to an off-site third-party."
"Wow that's really impressive," Alice says, "but what if we need access for a withdrawal outside of office hours?" "Well that's no issue", Bob says, "just send us an email, call, or text message and we always have someone on staff to help out. Just another part of our strong commitment to all our customers!"

"What about Proof of Reserve?", Alice asks. "Of course", Bob replies, "though rather than publish any blockchain addresses or signed transaction, for privacy we just do a SHA256 refactoring of the inverse hash modulus for each UTXO nonce and combine the smart contract coefficient consensus in our hyperledger lightning node. But it's really simple to use." He pushes a button and a large green checkmark appears on a screen. "See - the algorithm ran through and reserves are proven."
"Wow", Alice says, "you really know your stuff! And that is easy to use! What about fiat balances?" "Yeah, we have an auditor too", Bob replies, "Been using him for a long time so we have quite a strong relationship going! We have special books we give him every year and he's very efficient! Checks the fiat, crypto, and everything all at once!"

"We used to have a nice offline multi-sig setup we've been using without issue for the past 5 years, but I think we'll move all our funds over to your facility," Alice says. "Awesome", Bob replies, "Thanks so much! This is perfect timing too - my Porsche got a dent on it this morning. We have the paperwork right over here." "Great!", Alice replies.
And with that, Alice gets out her pen and Bob gets the contract. "Don't worry", he says, "you can take your crypto-assets back anytime you like - just subject to our cancellation policy. Our annual management fees are also super low and we don't adjust them often".

How many holes have to exist for your funds to get stolen?
Just one.

Why are we taking a powerful offline multi-sig setup, widely used globally in hundreds of different/lacking regulatory environments with 0 breaches to date, and circumventing it by a demonstrably weak third party layer? And paying a great expense to do so?
If you go through the list of breaches in the past 2 years to highly credible organizations, you go through the list of major corporate frauds (only the ones we know about), you go through the list of all the times platforms have lost funds, you go through the list of times and ways that people have lost their crypto from identity theft, hot wallet exploits, extortion, etc... and then you go through this custodian with a fine-tooth comb and truly believe they have value to add far beyond what you could, sticking your funds in a wallet (or set of wallets) they control exclusively is the absolute worst possible way to take advantage of that security.

The best way to add security for crypto-assets is to make a stronger multi-sig. With one custodian, what you are doing is giving them your cryptocurrency and hoping they're honest, competent, and flawlessly secure. It's no different than storing it on a really secure exchange. Maybe the insurance will cover you. Didn't work for Bitpay in 2015. Didn't work for Yapizon in 2017. Insurance has never paid a claim in the entire history of cryptocurrency. But maybe you'll get lucky. Maybe your exact scenario will buck the trend and be what they're willing to cover. After the large deductible and hopefully without a long and expensive court battle.

And you want to advertise this increase in risk, the lapse of judgement, an accident waiting to happen, as though it's some kind of benefit to customers ("Free institutional-grade storage for your digital assets.")? And then some people are writing to the OSC that custodians should be mandatory for all funds on every exchange platform? That this somehow will make Canadians as a whole more secure or better protected compared with standard air-gapped multi-sig? On what planet?

Most of the problems in Canada stemmed from one thing - a lack of transparency. If Canadians had known what a joke Quadriga was - it wouldn't have grown to lose $400m from hard-working Canadians from coast to coast to coast. And Gerald Cotten would be in jail, not wherever he is now (at best, rotting peacefully). EZ-BTC and mister Dave Smilie would have been a tiny little scam to his friends, not a multi-million dollar fraud. Einstein would have got their act together or been shut down BEFORE losing millions and millions more in people's funds generously donated to criminals. MapleChange wouldn't have even been a thing. And maybe we'd know a little more about CoinTradeNewNote - like how much was lost in there. Almost all of the major losses with cryptocurrency exchanges involve deception with unbacked funds.
So it's great to see transparency reports from BitBuy and ShakePay where someone independently verified the backing. The only thing we don't have is:
It's not complicated to validate cryptocurrency assets. They need to exist, they need to be spendable, and they need to cover the total balances. There are plenty of credible people and firms across the country that have the capacity to reasonably perform this validation. Having more frequent checks by different, independent, parties who publish transparent reports is far more valuable than an annual check by a single "more credible/official" party who does the exact same basic checks and may or may not publish anything. Here's an example set of requirements that could be mandated:
There are ways to structure audits such that neither crypto assets nor customer information are ever put at risk, and both can still be properly validated and publicly verifiable. There are also ways to structure audits such that they are completely reasonable for small platforms and don't inhibit innovation in any way. By making the process as reasonable as possible, we can completely eliminate any reason/excuse that an honest platform would have for not being audited. That is arguable far more important than any incremental improvement we might get from mandating "the best of the best" accountants. Right now we have nothing mandated and tons of Canadians using offshore exchanges with no oversight whatsoever.

Transparency does not prove crypto assets are safe. CoinTradeNewNote, Flexcoin ($600k), and Canadian Bitcoins ($100k) are examples where crypto-assets were breached from platforms in Canada. All of them were online wallets and used no multi-sig as far as any records show. This is consistent with what we see globally - air-gapped multi-sig wallets have an impeccable record, while other schemes tend to suffer breach after breach. We don't actually know how much CoinTrader lost because there was no visibility. Rather than publishing details of what happened, the co-founder of CoinTrader silently moved on to found another platform - the "most trusted way to buy and sell crypto" - a site that has no information whatsoever (that I could find) on the storage practices and a FAQ advising that “[t]rading cryptocurrency is completely safe” and that having your own wallet is “entirely up to you! You can certainly keep cryptocurrency, or fiat, or both, on the app.” Doesn't sound like much was learned here, which is really sad to see.
It's not that complicated or unreasonable to set up a proper hardware wallet. Multi-sig can be learned in a single course. Something the equivalent complexity of a driver's license test could prevent all the cold storage exploits we've seen to date - even globally. Platform operators have a key advantage in detecting and preventing fraud - they know their customers far better than any custodian ever would. The best job that custodians can do is to find high integrity individuals and train them to form even better wallet signatories. Rather than mandating that all platforms expose themselves to arbitrary third party risks, regulations should center around ensuring that all signatories are background-checked, properly trained, and using proper procedures. We also need to make sure that signatories are empowered with rights and responsibilities to reject and report fraud. They need to know that they can safely challenge and delay a transaction - even if it turns out they made a mistake. We need to have an environment where mistakes are brought to the surface and dealt with. Not one where firms and people feel the need to hide what happened. In addition to a knowledge-based test, an auditor can privately interview each signatory to make sure they're not in coercive situations, and we should make sure they can freely and anonymously report any issues without threat of retaliation.
A proper multi-sig has each signature held by a separate person and is governed by policies and mutual decisions instead of a hierarchy. It includes at least one redundant signature. For best results, 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7.

History has demonstrated over and over again the risk of hot wallets even to highly credible organizations. Nonetheless, many platforms have hot wallets for convenience. While such losses are generally compensated by platforms without issue (for example Poloniex, Bitstamp, Bitfinex, Gatecoin, Coincheck, Bithumb, Zaif, CoinBene, Binance, Bitrue, Bitpoint, Upbit, VinDAX, and now KuCoin), the public tends to focus more on cases that didn't end well. Regardless of what systems are employed, there is always some level of risk. For that reason, most members of the public would prefer to see third party insurance.
Rather than trying to convince third party profit-seekers to provide comprehensive insurance and then relying on an expensive and slow legal system to enforce against whatever legal loopholes they manage to find each and every time something goes wrong, insurance could be run through multiple exchange operators and regulators, with the shared interest of having a reputable industry, keeping costs down, and taking care of Canadians. For example, a 4 of 7 multi-sig insurance fund held between 5 independent exchange operators and 2 regulatory bodies. All Canadian exchanges could pay premiums at a set rate based on their needed coverage, with a higher price paid for hot wallet coverage (anything not an air-gapped multi-sig cold wallet). Such a model would be much cheaper to manage, offer better coverage, and be much more reliable to payout when needed. The kind of coverage you could have under this model is unheard of. You could even create something like the CDIC to protect Canadians who get their trading accounts hacked if they can sufficiently prove the loss is legitimate. In cases of fraud, gross negligence, or insolvency, the fund can be used to pay affected users directly (utilizing the last transparent balance report in the worst case), something which private insurance would never touch. While it's recommended to have official policies for coverage, a model where members vote would fully cover edge cases. (Could be similar to the Supreme Court where justices vote based on case law.)
Such a model could fully protect all Canadians across all platforms. You can have a fiat coverage governed by legal agreements, and crypto-asset coverage governed by both multi-sig and legal agreements. It could be practical, affordable, and inclusive.

Now, we are at a crossroads. We can happily give up our freedom, our innovation, and our money. We can pay hefty expenses to auditors, lawyers, and regulators year after year (and make no mistake - this cost will grow to many millions or even billions as the industry grows - and it will be borne by all Canadians on every platform because platforms are not going to eat up these costs at a loss). We can make it nearly impossible for any new platform to enter the marketplace, forcing Canadians to use the same stagnant platforms year after year. We can centralize and consolidate the entire industry into 2 or 3 big players and have everyone else fail (possibly to heavy losses of users of those platforms). And when a flawed security model doesn't work and gets breached, we can make it even more complicated with even more people in suits making big money doing the job that blockchain was supposed to do in the first place. We can build a system which is so intertwined and dependent on big government, traditional finance, and central bankers that it's future depends entirely on that of the fiat system, of fractional banking, and of government bail-outs. If we choose this path, as history has shown us over and over again, we can not go back, save for revolution. Our children and grandchildren will still be paying the consequences of what we decided today.
Or, we can find solutions that work. We can maintain an open and innovative environment while making the adjustments we need to make to fully protect Canadian investors and cryptocurrency users, giving easy and affordable access to cryptocurrency for all Canadians on the platform of their choice, and creating an environment in which entrepreneurs and problem solvers can bring those solutions forward easily. None of the above precludes innovation in any way, or adds any unreasonable cost - and these three policies would demonstrably eliminate or resolve all 109 historic cases as studied here - that's every single case researched so far going back to 2011. It includes every loss that was studied so far not just in Canada but globally as well.
Unfortunately, finding answers is the least challenging part. Far more challenging is to get platform operators and regulators to agree on anything. My last post got no response whatsoever, and while the OSC has told me they're happy for industry feedback, I believe my opinion alone is fairly meaningless. This takes the whole community working together to solve. So please let me know your thoughts. Please take the time to upvote and share this with people. Please - let's get this solved and not leave it up to other people to do.

The events of a SIM swap attack (and defense tips)

Posted this on Coinbase and someone recommend it also be posted here. The information below on an attempted SIM swap attack was pieced together through a combination of login and security logs, recovering emails initiated by the attacker that were deleted and then deleted again from the trash folder, and learning from AT&T’s fraud representatives. The majority if this is factual, and we do our best to note where we are speculating or providing a circumstantial suspicion. TLDRs at the bottom.
The full story:
We were going about our business and received a text from AT&T that says “…Calls & texts will go to your new phone/SIM card. Call 866-563-4705 if you did not request.” We did not request this, and were suspicious that the text itself could be a phishing scam since we searched the phone number and it wasn’t overtly associated with AT&T. Thus, we tried calling AT&T’s main line at 611 but all we hear is beep beep beep. The phone number is already gone. We use another phone to call AT&T and at the same time start working on our already compromised email.
While we didn’t see everything real time, this is what the recovered emails show. In less than 2 minutes after receiving the text from AT&T, there is already an email indicating that the stolen phone number was used to sign into our email account associated with Coinbase. 2 minutes after that, there is an email from Coinbase saying:
"We have received your request for password reset from an unverified device. As a security precaution, an e-mail with a reset link will be sent to you in 24 hours. Alternatively, if you would like your password reset to be processed immediately, please submit a request using a verified device.
This 24 hour review period is designed to protect your Coinbase account."
This is where Coinbase got it right to have a 24 hour review period (actually a recovery period) before allowing the password to be reset. However, the attackers knew this and planned to steal the second email from Coinbase by setting email rules to forward all emails to a burner address and also have any emails containing “coinbase” re-routed so they don’t appear in the Inbox. 5 minutes later, they request a password reset from Gemini and the password was reset to the attacker’s password within a minute after that. The next minute they target and reset DropBox’s password followed immediately with Binance. Less than 2 minutes later, an email from Binance indicates that the password has been reset and another email arrives a minute later indicating a new device has been authorized.
It’s at this point that we begin locking the attacker out by (1) removing the phone number as 2FA (2) changing the email password, (3) and three forcing a logout of all sessions from the email. There was a bit of back and forth where they still had an active login and re-added the stolen phone number as 2FA.
They added only one more password reset to a gaming account that was not deleted. I can only suspect that was a decoy to make it look like the attack was directed at gaming rather than finances.
The Gemini and Binance accounts were empty and effectively abandoned, with no balances and inactive bank accounts (if any), and no transactions in 1-3 years. DropBox had no meaningful files (they probably look for private keys and authenticator backups) and the phone number they stole from us was suspended, so as far as the attacker is concerned, there is no meat on this bone to attack again… unless they had inside information.
This is where I suspect someone internal at Coinbase receiving wire deposits has been compromised in tipping off ripe accounts – accounts with new and somewhat large balances. We had completed a full withdrawal of funds from Coinbase earlier in the year, and had a balance of less than $20 heading into May. Deposits to Coinbase staggered in to get above six figures through mid-May then stopped. The attack occurred 7 days after the last large wire deposit was made to Coinbase.
From the perspective of an attacker that had no inside information, we were a dead end with abandoned Gemini and Binance accounts with zero balances and stale transactions, no DropBox information, and the suspended phone number access. Our Coinbase deposits were known to no one except us, Coinbase, and our bank. We were also able to stop the hacker’s email forwarding before Coinbase’s 24 hour period to send the password reset, so this one didn’t work out for the attackers and it would make sense for them to move on to the next rather than put efforts into a second attack only for Coinbase - for what would appear to be a zero-balance Coinbase account based on the other stale accounts.
Then…23 hours and 42 minutes after the first attack, another message from AT&T “…Calls & texts will go to your new phone/SIM card. Call 866-563-4705 if you did not request.” Here we go again. We had been confident in AT&T’s assurances that our account had been locked and would not be SIM swapped again, so we unwisely added the phone number back to our email account as a backup (it’s now removed permanently and we use burner emails for account recovery like we should have all along).
Upon seeing that our phone number had been stolen again I knew they were after the Coinbase reset email that was delayed by 24 hours from Coinbase as part of their security. We did 4 things within 2 minutes of that text: (1) removed the phone number again from the email account – this time for good, (2) market sell all Bitcoin on Coinbase, (3) withdraw from Coinbase, (4) have AT&T suspend service on the phone line.
In speaking with AT&T, they were floored that our SIM would be transferred again in light of all the notes about fraud on the account and the PIN being changed to random digits that had never been used by us before. Based on the response of disbelief from AT&T on the second port, I suspect that this attack also involved a compromised AT&T employee that worked with the attacker to provide timely access to the Coinbase password reset email. Apparently, this has been going on for years: https://www.flashpoint-intel.com/blog/sim-swap-fraud-account-takeove
with phone carrier employees swapping SIMs for $80s a swap.
Remember that most of this was hidden in real time, and was only known because we were able to recover emails deleted from Trash by the attacker.
Since we require any withdrawals to use Google Authenticator on Coinbase, our funds may have been secure nonetheless. However, under the circumstances with attackers that were apparently working with insiders to take our phone number twice in attempts to steal Bitcoin, and it being unknown if they had additional tools related to our Google Authenticator, we decided it was safer on the sidelines. The coins were held on the exchange for a quick exit depending on whether Bitcoin was going to break up or down from $10,000. A hardware wallet is always safest, but we were looking to time the market and not have transaction delays.
For some some security recommendations:
AT&T: If you are going to send a text saying that calls and texts are moving to a new number, provide a 10 minute window for the phone number to reply with a “NO” or “STOP” to prevent the move. This can escalate the SIM dispute to more trusted employees to determine who actually owns the line. Don’t let entry level employees swap SIMs.
Coinbase: Do not default to phone numbers as 2FA. Also, if someone logs in successfully with the password before the 24 hours are up, the password is known and there is no need to send the password reset email again for attacker to have forwarded to them. At least have an option to stop the password reset email from being sent. We did not tag our account at Coinbase with fraud because of the stories of frozen funds once an account is tagged. I’m not sure what the solution is there, but that is another problem.
Being a trader, it would be nice to think of Coinbase as any other type of security brokerage where your assets are yours (someone can’t steal your phone number and transfer your stocks to their account). We fell into that mindset of security, yet this experience has reminded us of the uniqueness of cryptocurrency and the lack of custodial assurance and insurance from exchanges because of the possession-is-everything properties of cryptocurrency.
As many have said before, 2FA with a phone number quickly becomes 1-factor authentication as soon as that phone number is associated with password recovery on your email or other accounts. Our overall recommendation is to avoid having a phone number associated with any recovery options across all your accounts.
TLDR on the process:
Scammers will steal your phone number (in our case twice in 24 hours) and use your phone number to access your email and accounts. They will use your email to reset passwords at financial accounts and file hosting such as DropBox. They will then use that combination to transfer any assets they can access from your accounts to theirs. They will do their best to hide this from you by
(1) not resetting your email password so as to raise suspicion,
(2) immediately delete any password reset emails you may receive from financial accounts to hide them from you,
(3) attempt to forward all emails sent to your address to a burner email, and
(4) set email rules to forward emails containing “coinbase” to an email folder other than your Inbox so that you don’t see the transactions and password reset emails that arrive to your inbox.
TLDR on defense tips: If your phone stops working or you receive a text of your number being ported do the following as soon as possible:
(1) log into your email account(s) associated with your financial accounts and remove your phone number as 2FA immediately
(2) change your email password,
(3) force a logout of all sessions from your email (at this point you have locked them out), then
(4) check your mail forwarding settings for forwards to burner addresses,
(5) check your mail rules for rerouting of emails from accounts such as Coinbase, and
(6) call your carrier to have them suspend service on your lost phone number and ask them to reinstate your SIM or get a new SIM. This will require a second phone because your personal phone number has been stolen.
We hope this helps some others be safe out there in protecting their coins. The more we know, the more we can protect ourselves. Wishing you all the best!

(2) immediately delete any password reset emails you may receive from financial accounts to hide them from you,
(3) attempt to forward all emails sent to your address to a burner email, and
(4) set email rules to forward emails containing “coinbase” to an email folder other than your Inbox so that you don’t see the transactions and password reset emails that arrive to your inbox.
TLDR on defense tips: If your phone stops working or you receive a text of your number being ported do the following as soon as possible:
(1) log into your email account(s) associated with your financial accounts and remove your phone number as 2FA immediately
(2) change your email password,
(3) force a logout of all sessions from your email (at this point you have locked them out), then
(4) check your mail forwarding settings for forwards to burner addresses,
(5) check your mail rules for rerouting of emails from accounts such as Coinbase, and
(6) call your carrier to have them suspend service on your lost phone number and ask them to reinstate your SIM or get a new SIM. This will require a second phone because your personal phone number has been stolen.
We hope this helps some others be safe out there in protecting their coins. The more we know, the more we can protect ourselves. Wishing you all the best!

Your Goals

  • Create a high-quality infographic that illustrates the genesis of our platform, the working tech that has been created and how Komodo has been built differently, and deliberately, from the very beginning to ensure security, scalability and interoperability. This is why we refer to the architecture, because Komodo was designed to overcome common problems like congestion, governance and attacks that other platforms did not foresee or prevent, from the beginning. This is Komodo DNA.
  • Share your submission far and wide and encourage your friends and followers to vote for you.
  • Encourage feedback, ask questions and make your infographic the best that it can be.

Our Criteria to Judge

Please note that upvotes and shares are not the only criteria we'll use to judge winners. While useful, we will value creativity, good questions and discussion on Reddit highly. When sharing your posts you will score more highly if people comment, provide feedback and are engaged.
  • How well the infographic conveys our working tech, it's core concepts and plans to build on top of it.
  • How well the infographic illustrates our story, purpose and conveys our tech so that it's easy to understand.
  • Constructive discussion, questions and feedback on Reddit that lead to improvement.
  • Sentiment and comments generated across all our social media. This will not include vanity metrics like likes or shares.
  • Upvotes on Reddit for the author's submission post ONLY. All votes will be counted (i.e. doesn't matter which week they were made).
  • Retweets of the submission in our master thread ONLY. Include your handle and a cover image in your submission. This means if you promote yourself on Twitter you ought to promote the tweet with your work in it.

25/09/18 - First Round of Feedback

Infographics should use graphical design elements to visually represent the Komodo Architecture Story found here: https://komodoplatform.com/komodo-platform-a-brief-overview/ included in our ‘required reading’. There’s also a bullet point aid: https://medium.com/@benohanlon/bullet-point-aid-to-help-you-the-history-of-komodos-architecture-dced35b29965 you may find useful.
  • We want to stress that the infographic ought to focus on the Architecture story. In the first round we've found many have focused on the five pillars which is a part of it but not the focus.
  • Copy should be short and concise and not dominate the infographic. The idea is to simplify the story and not to copy and paste directly from the story.
  • Colour Palette - avoid heavy usage of the old KMD green and yellow-orange. Would prefer usage of the interim KMD colour palette.
  • Recommended fonts: Montseratt, Roboto, Open Sans, Helvetica, or Arial.
  • Graphical - Imagery should complement the associated copy. Diagrams are encouraged in place of simple icons to explain more complex technology concepts.
  • Interim KMD colour palette
Interim KMD Colour Palette
If you’ve not been included in the first round it’s because the submission hadn’t been made when the team reviewed. Don’t worry though because we’re organising hangouts and further feedback to help.
  • #001 Infographic Link // Reddit Post Link by thesudio. There’s a lot of good points made, however, these would work better if there is a clear narrative and flow to the information being presented. Otherwise, it can be overwhelming and confusing to the reader. The #1 objective is to visually depict the architecture story and how KMD is redefining blockchain platform architecture.
  • #002 Infographic Link // Reddit Post Link by thesudio. We like that there is a clear structure and clear messaging aligned to each of the 5 pillars. However, the infographic should be focused on telling the architecture story vs the pillars.
  • #003 Infographic Link // Reddit Post Link by VolsenVols. Love how you’ve incorporated our existing graphic design elements into the infographic. This is heading in the right direction and the level of copy and content are well balanced. It would be nice to align this closer to the architecture story and to expand on the different layers of our technology using the same style.
  • #004 Infographic Link // Reddit Post Link by dexter_laabo. Needs to tell the architecture story. This looks more like it took information from our current website. “Anonymous” is not a key aspect of our technology that we’re focusing on.
  • #005 Infographic Link // Reddit Post Link by savandra. The visuals are strong but the narrative could be stronger. It would be nice to align this closer to the architecture story and to expand on the different layers of our technology using the same style.
  • #006 Infographic Link // Reddit Post Link by VolsenVols. Team prefers the other submission style in entry #003.
  • #007 Infographic Link // Reddit Post Link by cryptol1. Doesn’t depict the architecture narrative. Inaccurately describes cross-chain tech as “proprietary”. Simplification has the wrong messaging associated, should be white-label focused. This is considered more of a graphics versus an infographic. Needs to be more comprehensive.
  • #008 Infographic Link // Reddit Post Link by pacosenda. We like the unique design style and approach taken. Doesn’t follow the architecture narrative. Should be expanded out as it is a bit short on content with no clear flow or narrative.
  • #009 Infographic Link // Reddit Post Link by jeanetteLine. Great level of detail and thought on the layout and content. Doesn’t, however, cover the architecture story. Would be preferred if the design direction reflects interim colour and style vs. legacy KMD. The roadmap should be avoided. Looks like they borrowed more from the website than the guidelines.
  • #010 Infographic Link // Reddit Post Link by Meyse. Very creative way to explain and layout the content. This could be expanded out more to encompass the entire architecture story. Cross-chain verifications/smart contracts, blockchain bridging need to be incorporated in.
  • #011 Infographic Link // Reddit Post Link by Brenny431. Follows the 5 pillars versus the architecture story. Would prefer stronger visuals and design elements.
  • #012 Infographic Link // Reddit Post Link by ProofDraw. Design elements are good but need to follow architecture story versus 5 pillars.
  • #013 Infographic Link // Reddit Post Link by sayonara_girl. Needs to follow the architecture story.
  • #014 Infographic Link // Reddit Post Link by Limiter02. Good thought has gone into the copy, however, there’s way too much of it. Would prefer stronger visuals and utilizing a more visual storytelling approach. Doesn’t follow the architecture story. Remove the lizard.
  • #015 Infographic Link // Reddit Post Link by piptothemoon. Great thought into visually representing key points. Needs to be expanded out to incorporate the architecture story, but this is heading in the right direction from a visual storytelling POV.
  • #016 Infographic Link // Reddit Post Link by thecryptofoundation. Love the timeline approach, and mostly followed the guidelines and architecture story. Also, like the incorporation of accomplishments at the end. Would like to get the stock imagery used to reflect our interim colour palette. Not all visuals match what is being represented in the copy.
  • #017 Infographic Link // Reddit Post Link by jsteneros. As discussed in the Zoom call, this graphic is really solid but a little heavy on the copy. Would be good to see more visualizations of the info. This graphic hits on some of the important messages (e.g. Komodo is built differently from other blockchain platforms and solves many of the issues that first-gen platforms are struggling with) but it would be great if there was more information about Komodo’s architecture and how Komodo is different from other platforms.
  • #018 Infographic Link // Reddit Post Link by gravigocrypto. This one was also discussed in the Zoom call. Outstanding visuals and overall design. The info follows the architecture story well but could be stronger if the 3 layers of Komodo’s architecture were tied together into one, coherent visual. It’s a challenging task but that’s part of the contest : )
  • #019 Infographic Link // Reddit Post Link by PacoSenda. This is a really creative infographic, which is great! However, we’d really like to see the visuals a bit more in line with fonts and color palette described above in the “First Round of Feedback” section. Also, as with the feedback for many of the infographic submissions, sticking to the Komodo architecture story would be best.
  • #020 Infographic Link // Reddit Post Link by emmanmalaman. The visuals are pretty cool but this one misses most of our core messaging. It would be much stronger if it followed the architecture story and touched on the info provided in this post. There’s definitely potential here but it needs some work.
  • #021 Infographic Link // Reddit Post Link by immimidada. The colors and visuals here are spot-on. It’s also really great that it sets up the problem and then presents the Komodo solution. However, the problem and solution aren’t defined exactly the way we’d like. Check out the architecture narrative to learn more, and try to follow that story a bit more closely.
  • #022 Infographic Link // Reddit Post Link by mohitgfx3. This one is a bit heavy on the KMD logos. We’re really hoping to see a visualization of Komodo’s infrastructure architecture. As with the feedback for many of the infographics, it would be best to re-read Komodo’s architecture story and try to stick to that as much as possible. Using images from the current website is also not a great approach, as we’re preparing to launch a new site in the coming months.
  • #023 Infographic Link // Reddit Post Link by u/sayonara_girl. Some of the visuals are cool! It’s missing the narrative we’re looking for. In general, less copy and more visual storytelling would improve this graphic a lot. We’d like to see a smooth, linear flow of information. Take another look at the architecture story and try to follow that narrative.
  • #024 Infographic Link // Reddit Post Link by brunopugens. This one follows the narrative well! But it’s a little heavy on the copy. It would be much stronger if the architecture was displayed visually, rather than explained with text. Also, the design is cool but it’s difficult to read b/c the perspective of the text is skewed. It’s a really cool idea but might be better to put the text flat for the sake of readability and clarity.

We hosted a round of live feedback sessions via Zoom. The recording is here:

Day 5: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and transaction fees are low. User demand from this community can help lead to some big changes. Have you joined the /r/Bitcoin SegWit effort?

SUMMARY
Segregrated Witness (SegWit) was activated on the Bitcoin network August 24, 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work. If users demand SegWit now it will temporarily releive the transaction backlog while bigger solutions like Lightning are developed.
TODAY's NEWS/DEVELOPMENTS/VICTORIES
MEMPOOL/SEGWIT STATISTICS
BACKGROUND
Subhan Nadeem has pointed out that:
If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
A few thousand bitcoin users from /Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP. Let's make 80%+ SegWit happen fast. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin.
  4. Spread the word! Conact individuals, websites, etc that use bitcoin, explain the benefits of SegWit to everyone, and request they make the switch
IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange.

FAQs
If I'm a HODLer, will it help to send my BTC to a SegWit address now?
  • No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unneccessary transactions for now.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
  • The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download Electrum v3.0.3 to generate a SegWit address.
    A transaction between two SegWit addresses is a SegWit transaction.
    A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.
    A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Tx if the sending address is a SegWit address.
    Source
What wallet are you using to "batch your sends"? And how can I do that?
  • Using Electrum, the "Tools" menu option: "Pay to many".
    Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.
Why doesn't the Core Wallet yet support SegWit?
  • The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in
Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?

Which are your top 5 coins out of the top100? An analysis.

I am putting together my investment portfolio for 2018 and made a complete summary of the current Top 100. Interestingly, I noticed that all coins can be categorized into 12 markets. Which markets do you think will play the biggest role in the coming year?
Here is a complete overview of all coins in an excel sheet including name, a full description, market, TPS, risk profile, time since launch (negative numbers mean that they are launching that many months in the future) and market cap. You can also sort by all of these fields of course. Coins written in bold are the strongest contenders within their market either due to having the best technology or having a small market cap and still excellent technology and potential. https://docs.google.com/spreadsheets/d/1s8PHcNvvjuy848q18py_CGcu8elRGQAUIf86EYh4QZo/edit#gid=0
The 12 markets are
  1. Currency 13 coins
  2. Platform 25 coins
  3. Ecosystem 9 coins
  4. Privacy 9 coins
  5. Currency Exchange Tool 8 coins
  6. Gaming & Gambling 4 coins
  7. Misc 15 coins
  8. Social Network 4 coins
  9. Fee Token 3 coins
  10. Decentralized Data Storage 4 coins
  11. Cloud Computing 2 coins
  12. Stable Coin 3 coins
Before we look at the individual markets, we need to take a look of the overall market and its biggest issue, scalability, first:
Cryptocurrencies aim to be a decentralized currency that can be used worldwide. Their goal is to replace dollar, Euro, Yen, all FIAT currencies globally. The coin that will achieve that will be worth several trillion dollars.
Bitcoin can only process 7 transactions per second (TPS) currently. In order to replace all FIAT, it would need to perform at least at VISA levels, which usually processes around 3,000 TPS, up to 25,000 TPS during peak times and a maximum of 64,000 TPS. That means that this cryptocurrency would need to be able to perform at least several thousand TPS. However, a ground breaking technology should not look at current technology to set a goal for its use, i.e. estimating the number of emails sent in 1990 based on the number of faxes sent wasn’t a good estimate.
For that reason, 10,000 TPS is the absolute baseline for a cryptocurrency that wants to replace FIAT. This brings me to IOTA, which wants to connect all 80 billion IoT devices that are expected to exist by 2025, which constantly communicate with each other, possibly creating 80 billion or more transactions per second. This is the benchmark that cryptocurrencies should be aiming for. Currently, 8 billion devices are connected to the Internet.
With its Lightning network recently launched, Bitcoin is realistically looking at 50,000 possible TPS soon. Other notable cryptocurrencies besides IOTA and Bitcoin are Nano with 7,000 TPS already tested, Dash with several billion TPS possible with Masternodes, Neo, LISK and RHOC with 100,000 TPS by 2020, Ripple with 50,000 TPS, Ethereum with 10,000 TPS with Sharding.
However, it needs to be said that scalability usually goes at the cost of decentralization and security. So, it needs to be seen, which of these technologies can prove themselves decentralized while maintaining high TPS.
Without further ado, here are the coins of the first market. Each market is sorted by market cap.

Market 1 - Currency:

  1. Bitcoin: 1st generation blockchain with currently bad scalability, though the implementation of the Lightning Network looks promising and could alleviate most scalability and high energy use concerns.
  2. Ripple: Centralized currency that might become very successful due to tight involvement with banks and cross-border payments for financial institutions; banks and companies like Western Union and Moneygram (who they are currently working with) as customers customers. However, it seems they are aiming for more decentralization now.https://ripple.com/dev-blog/decentralization-strategy-update/. Has high TPS due to Proof of Correctness algorithm.
  3. Bitcoin Cash: Bitcoin fork with the difference of having an 8 times bigger block size, making it 8 times more scalable than Bitcoin currently. Further block size increases are planned. Only significant difference is bigger block size while big blocks lead to further problems that don't seem to do well beyond a few thousand TPS. Opponents to a block size argue that increasing the block size limit is unimaginative, offers only temporary relief, and damages decentralization by increasing costs of participation. In order to preserve decentralization, system requirements to participate should be kept low. To understand this, consider an extreme example: very big blocks (1GB+) would require data center level resources to validate the blockchain. This would preclude all but the wealthiest individuals from participating.Community seems more open than Bitcoin's though.
  4. Litecoin : Little brother of Bitcoin. Bitcoin fork with different mining algorithm but not much else.Copies everything that Bitcoin does pretty much. Lack of real innovation.
  5. Dash: Dash (Digital Cash) is a fork of Bitcoin and focuses on user ease. It has very fast transactions within seconds, low fees and uses Proof of Service from Masternodes for consensus. They are currently building a system called Evolution which will allow users to send money using usernames and merchants will find it easy to integrate Dash using the API. You could say Dash is trying to be a PayPal of cryptocurrencies. Currently, cryptocurrencies must choose between decentralization, speed, scalability and can pick only 2. With Masternodes, Dash picked speed and scalability at some cost of decentralization, since with Masternodes the voting power is shifted towards Masternodes, which are run by Dash users who own the most Dash.
  6. IOTA: 3rd generation blockchain called Tangle, which has a high scalability, no fees and instant transactions. IOTA aims to be the connective layer between all 80 billion IOT devices that are expected to be connected to the Internet in 2025, possibly creating 80 billion transactions per second or 800 billion TPS, who knows. However, it needs to be seen if the Tangle can keep up with this scalability and iron out its security issues that have not yet been completely resolved.
  7. Nano: 3rd generation blockchain called Block Lattice with high scalability, no fees and instant transactions. Unlike IOTA, Nano only wants to be a payment processor and nothing else, for now at least. With Nano, every user has their own blockchain and has to perform a small amount of computing for each transaction, which makes Nano perform at 300 TPS with no problems and 7,000 TPS have also been tested successfully. Very promising 3rd gen technology and strong focus on only being the fastest currency without trying to be everything.
  8. Decred: As mining operations have grown, Bitcoin’s decision-making process has become more centralized, with the largest mining companies holding large amounts of power over the Bitcoin improvement process. Decred focuses heavily on decentralization with their PoW Pos hybrid governance system to become what Bitcoin was set out to be. They will soon implement the Lightning Network to scale up. While there do not seem to be more differences to Bitcoin besides the novel hybrid consensus algorithm, which Ethereum, Aeternity and Bitcoin Atom are also implementing, the welcoming and positive Decred community and professoinal team add another level of potential to the coin.
  9. Bitcoin Atom: Atomic Swaps and hybrid consenus. This looks like the only Bitcoin clone that actually is looking to innovate next to Bitcoin Cash.
  10. Dogecoin: Litecoin fork, fantastic community, though lagging behind a bit in technology.
  11. Bitcoin Gold: A bit better security than bitcoin through ASIC resistant algorithm, but that's it. Not that interesting.
  12. Digibyte: Digibyte's PoS blockchain is spread over a 100,000+ servers, phones, computers, and nodes across the globe, aiming for the ultimate level of decentralization. DigiByte’s adoption over the past four years has been slow. The DigiByte website offers a lot of great marketing copy and buzzwords. However, there’s not much technical information about what they have planned for the future. You could say Digibyte is like Bitcoin, but with shorter blocktimes and a multi-algorithm. However, that's not really a difference big enough to truly set themselves apart from Bitcoin, since these technologies could be implemented by any blockchain without much difficulty. Their decentralization is probably their strongest asset, however, this also change quickly if the currency takes off and big miners decide to go into Digibyte.
  13. Bitcoin Diamond Asic resistant Bitcoin and Copycat

Market 2 - Platform

Most of the cryptos here have smart contracts and allow dapps (Decentralized apps) to be build on their platform and to use their token as an exchange of value between dapp services.
  1. Ethereum: 2nd generation blockchain that allows the use of smart contracts. Bad scalability currently, though this concern could be alleviated by the soon to be implemented Lightning Network aka the Raiden Network, Plasma and its Sharding concept.
  2. EOS: Promising technology that wants to be able do everything, from smart contracts like Ethereum, scalability similar to Nano with 1000 tx/second + near instant transactions and zero fees, to also wanting to be a platform for dapps. However, EOS doesn't have a product yet and everything is just promises still. There are lots of red flags, e.g. having dumped $500 million Ether over the last 2 months and possibly bought back EOS to increase the size of their ICO, which has been going on for over a year and has raised several billion dollars. All in all, their market cap is way too high for that and not even having a product. However, Mainnet release is in 1 month, which could change everything.
  3. Cardano: Similar to Ethereum/EOS, however, only promises made with no delivery yet, highly overrated right now. Interesting concept though. Market cap way too high for not even having a product. Somewhat promising technology.
  4. VeChain: Singapore-based project that’s building a business enterprise platform and inventory tracking system. Examples are verifying genuine luxury goods and food supply chains. Has one of the strongest communities in the crypto world. Most hyped token of all, with merit though.
  5. Neo: Neo is a platform, similar to Eth, but more extensive, allowing dapps and smart contracts, but with a different smart contract gas system, consensus mechanism (PoS vs. dBfT), governance model, fixed vs unfixed supply, expensive contracts vs nearly free contracts, different ideologies for real world adoption. There are currently only 9 nodes, each of which are being run by a company/entity hand selected by the NEO council (most of which are located in china) and are under contract. This means that although the locations of the nodes may differ, ultimately the neo council can bring them down due to their legal contracts. In fact this has been done in the past when the neo council was moving 50 million neo that had been locked up. Also dbft (or neo's implmentation of it) has failed underload causing network outages during major icos. The first step in decentralization is that the NEO Counsel will select trusted nodes (Universities, business partners, etc.) and slowly become less centralized that way. The final step in decentralization will be allowing NEO holders to vote for new nodes, similar to a DPoS system (ARK/EOS/LISK). NEO has a regulation/government friendly ideology. Finally they are trying to work undewith the Chinese government in regards to regulations. If for some reason they wanted it shut down, they could just shut it down.
  6. Stellar:PoS system, similar goals as Ripple, but more of a platform than only a currency. 80% of Stellar are owned by Stellar.org still, making the currency centralized.
  7. Ethereum classic: Original Ethereum that decided not to fork after a hack. The Ethereum that we know is its fork. Uninteresing, because it has a lot of less resources than Ethereum now and a lot less community support.
  8. Ziliqa: Zilliqa is building a new way of sharding. 2400 tpx already tested, 10,000 tps soon possible by being linearly scalable with the number of nodes. That means, the more nodes, the faster the network gets. They are looking at implementing privacy as well.
  9. QTUM: Enables Smart contracts on the Bitcoin blockchain. Useful.
  10. Icon: Korean ethereum. Decentralized application platform that's building communities in partnership with banks, insurance providers, hospitals, and universities. Focused on ID verification and payments.
  11. LISK: Lisk's difference to other BaaS is that side chains are independent to the main chain and have to have their own nodes. Similar to neo whole allows dapps to deploy their blockchain to. Like most cryptocurrencies, Lisk is currently somewhat centralized with a small group of members owning more than 50% of the delegated positions. Lisk plans to change the consensus algorithm for that reason in the near future.
  12. Rchain: Similar to Ethereum with smart contract, though much more scalable at an expected 40,000 TPS and possible 100,000 TPS. Not launched yet. No product launched yet, though promising technology. Not overvalued, probably at the right price right now.
  13. ARDR: Similar to Lisk. Ardor is a public blockchain platform that will allow people to utilize the blockchain technology of Nxt through the use of child chains. A child chain, which is a ‘light’ blockchain that can be customized to a certain extent, is designed to allow easy self-deploy for your own blockchain. Nxt claims that users will "not need to worry" about security, as that part is now handled by the main chain (Ardor). This is the chief innovation of Ardor. Ardor was evolved from NXT by the same company. NEM started as a NXT clone.
  14. Ontology: Similar to Neo. Interesting coin
  15. Bytom: Bytom is an interactive protocol of multiple byte assets. Heterogeneous byte-assets (indigenous digital currency, digital assets) that operate in different forms on the Bytom Blockchain and atomic assets (warrants, securities, dividends, bonds, intelligence information, forecasting information and other information that exist in the physical world) can be registered, exchanged, gambled and engaged in other more complicated and contract-based interoperations via Bytom.
  16. Nxt: Similar to Lisk
  17. Aeternity: We’ve seen recently, that it’s difficult to scale the execution of smart contracts on the blockchain. Crypto Kitties is a great example. Something as simple as creating and trading unique assets on Ethereum bogged the network down when transaction volume soared. Ethereum and Zilliqa address this problem with Sharding. Aeternity focuses on increasing the scalability of smart contracts and dapps by moving smart contracts off-chain. Instead of running on the blockchain, smart contracts on Aeternity run in private state channels between the parties involved in the contracts. State channels are lines of communication between parties in a smart contract. They don’t touch the blockchain unless they need to for adjudication or transfer of value. Because they’re off-chain, state channel contracts can operate much more efficiently. An important aspect of smart contract and dapp development is access to outside data sources. This could mean checking the weather in London, score of a football game, or price of gold. Oracles provide access to data hosted outside the blockchain. In many blockchain projects, oracles represent a security risk and potential point of failure, since they tend to be singular, centralized data streams. Aeternity proposes decentralizing oracles with their oracle machine. Doing so would make outside data immutable and unchangeable once it reaches Aeternity’s blockchain. Aeternity’s network runs on on a hybrid of proof of work and proof of stake. Founded by a long-time crypto-enthusiast and early colleague of Vitalik Buterin, Yanislav Malahov. Promising concept though not product yet
  18. Stratis: Different to LISK, Stratis will allow businesses and organizations to create their own blockchain according to their own needs, but secured on the parent Stratis chain. Stratis’s simple interface will allow organizations to quickly and easily deploy and/or test blockchain functionality of the Ethereum, BitShares, BitCoin, Lisk and Stratis environements.
  19. Status: Status provides access to all of Ethereum’s decentralized applications (dapps) through an app on your smartphone. It opens the door to mass adoption of Ethereum dapps by targeting the fastest growing computer segment in the world – smartphone users.
  20. Ark: Fork of Lisk that focuses on a smaller feature set. Ark wallets can only vote for one delegate at a time which forces delegates to compete against each other and makes cartel formations incredibly hard, if not impossible.
  21. Neblio: Similar to Neo, but at a 30x smaller market cap.
  22. NEM: Is similar to Neo. However, it has no marketing team, very high market cap for little clarilty what they do.
  23. Bancor: Bancor is a Decentralized Liquidity Network that allows you to hold any Ethereum token and convert it to any other token in the network, with no counter party, at an automatically calculated price, using a simple web wallet.
  24. Dragonchain: The Purpose of DragonChain is to help companies quickly and easily incorporate blockchain into their business applications. Many companies might be interested in making this transition because of the benefits associated with serving clients over a blockchain – increased efficiency and security for transactions, a reduction of costs from eliminating potential fraud and scams, etc.
  25. Skycoin: Transactions with zero fees that take apparently two seconds, unlimited transaction rate, no need for miners and block rewards, low power usage, all of the usual cryptocurrency technical vulnerabilities fixed, a consensus mechanism superior to anything that exists, resistant to all conceivable threats (government censorship, community infighting, cybenucleaconventional warfare, etc). Skycoin has their own consensus algorithm known as Obelisk written and published academically by an early developer of Ethereum. Obelisk is a non-energy intensive consensus algorithm based on a concept called ‘web of trust dynamics’ which is completely different to PoW, PoS, and their derivatives. Skywire, the flagship application of Skycoin, has the ambitious goal of decentralizing the internet at the hardware level and is about to begin the testnet in April. However, this is just one of the many facets of the Skycoin ecosystem. Skywire will not only provide decentralized bandwidth but also storage and computation, completing the holy trinity of commodities essential for the new internet. Skycion a smear campaign launched against it, though they seem legit and reliable. Thus, they are probably undervalued.

Market 3 - Ecosystem

The 3rd market with 11 coins is comprised of ecosystem coins, which aim to strengthen the ease of use within the crypto space through decentralized exchanges, open standards for apps and more
  1. Nebulas: Similar to how Google indexes webpages Nebulas will index blockchain projects, smart contracts & data using the Nebulas rank algorithm that sifts & sorts the data. Developers rewarded NAS to develop & deploy on NAS chain. Nebulas calls this developer incentive protocol – basically rewards are issued based on how often dapp/contract etc. is used, the more the better the rewards and Proof of devotion. Works like DPoS except the best, most economically incentivised developers (Bookkeeppers) get the forging spots. Ensuring brains stay with the project (Cross between PoI & PoS). 2,400 TPS+, DAG used to solve the inter-transaction dependencies in the PEE (Parallel Execution Environment) feature, first crypto Wallet that supports the Lightening Network.
  2. Waves: Decentralized exchange and crowdfunding platform. Let’s companies and projects to issue and manage their own digital coin tokens to raise money.
  3. Salt: Leveraging blockchain assets to secure cash loands. Plans to offer cash loans in traditional currencies, backed by your cryptocurrency assets. Allows lenders worldwide to skip credit checks for easier access to affordable loans.
  4. CHAINLINK: ChainLink is a decentralized oracle service, the first of its kind. Oracles are defined as an ‘agent’ that finds and verifies real-world occurrences and submits this information to a blockchain to be used in smart contracts.With ChainLink, smart contract users can use the network’s oracles to retrieve data from off-chain application program interfaces (APIs), data pools, and other resources and integrate them into the blockchain and smart contracts. Basically, ChainLink takes information that is external to blockchain applications and puts it on-chain. The difference to Aeternity is that Chainlink deploys the smart contracts on the Ethereum blockchain while Aeternity has its own chain.
  5. WTC: Combines blockchain with IoT to create a management system for supply chains Interesting
  6. Ethos unifyies all cryptos. Ethos is building a multi-cryptocurrency phone wallet. The team is also building an investment diversification tool and a social network
  7. Komodo: The Komodo blockchain platform uses Komodo’s open-source cryptocurrency for doing transparent, anonymous, private, and fungible transactions. They are then made ultra-secure using Bitcoin’s blockchain via a Delayed Proof of Work (dPoW) protocol and decentralized crowdfunding (ICO) platform to remove middlemen from project funding. Offers services for startups to create and manage their own Blockchains.
  8. Aion: Today, there are hundreds of blockchains. In the coming years, with widespread adoption by mainstream business and government, these will be thousands or millions. Blockchains don’t talk to each other at all right now, they are like the PCs of the 1980s. The Aion network is able to support custom blockchain architectures while still allowing for cross-chain interoperability by enabling users to exchange data between any Aion-compliant blockchains by making use of an interchain framework that allows for messages to be relayed between blockchains in a completely trust-free manner.
  9. Tenx: Raised 80 million, offers cryptocurrency-linked credit cards that let you spend virtual money in real life. Developing a series of payment platforms to make spending cryptocurrency easier.

Market 4 - Privacy

The 4th market are privacy coins. As you might know, Bitcoin is not anonymous. If the IRS or any other party asks an exchange who is the identity behind a specific Bitcoin address, they know who you are and can track back almost all of the Bitcoin transactions you have ever made and all your account balances. Privacy coins aim to prevent exactly that through address fungability, which changes addresses constantly, IP obfuscation and more. There are 2 types of privacy coins, one with completely privacy and one with optional privacy. Optional Privacy coins like Dash and Nav have the advantage of more user friendliness over completely privacy coins such as Monero and Enigma.
  1. Monero: Currently most popular privacy coin, though with a very high market cap. Since their privacy is all on chain, all prior transactions would be deanonymized if their protocol is ever cracked. This requires a quantum computing attack though. PIVX is better in that regard.
  2. Zcash: A decentralized and open-source cryptocurrency that hide the sender, recipient, and value of transactions. Offers users the option to make transactions public later for auditing. Decent privacy coin, though no default privacy
  3. Verge: Calls itself privacy coin without providing private transactions, multiple problems over the last weeks has a toxic community, and way too much hype for what they have.
  4. Bytecoin: First privacy-focused cryptocurrency with anonymous transactions. Bytecoin’s code was later adapted to create Monero, the more well-known anonymous cryptocurrency. Has several scam accusations, 80% pre-mine, bad devs, bad tech
  5. Bitcoin Private: A merge fork of Bitcoin and Zclassic with Zclassic being a fork of Zcash with the difference of a lack of a founders fee required to mine a valid block. This promotes a fair distribution, preventing centralized coin ownership and control. Bitcoin private offers the optional ability to keep the sender, receiver, and amount private in a given transaction. However, this is already offered by several good privacy coins (Monero, PIVX) and Bitcoin private doesn't offer much more beyond this.
  6. PIVX: As a fork of Dash, PIVX uses an advanced implementation of the Zerocoin protocol to provide it’s privacy. This is a form of zeroknowledge proofs, which allow users to spend ‘Zerocoins’ that have no link back to them. Unlike Zcash u have denominations in PIVX, so they can’t track users by their payment amount being equal to the amount of ‘minted’ coins, because everyone uses the same denominations. PIVX is also implementing Bulletproofs, just like Monero, and this will take care of arguably the biggest weakness of zeroknowledge protocols: the trusted setup.
  7. Zcoin: PoW cryptocurrency. Private financial transactions, enabled by the Zerocoin Protocol. Zcoin is the first full implementation of the Zerocoin Protocol, which allows users to have complete privacy via Zero-Knowledge cryptographic proofs.
  8. Enigma: Monero is to Bitcoin what enigma is to Ethereum. Enigma is for making the data used in smart contracts private. More of a platform for dapps than a currency like Monero. Very promising.
  9. Navcoin: Like bitcoin but with added privacy and pos and 1,170 tps, but only because of very short 30 second block times. Though, privacy is optional, but aims to be more user friendly than Monero. However, doesn't really decide if it wants to be a privacy coin or not. Same as Zcash.Strong technology, non-shady team.

Market 5 - Currency Exchange Tool

Due to the sheer number of different cryptocurrencies, exchanging one currency for the other it still cumbersome. Further, merchants don’t want to deal with overcluttered options of accepting cryptocurrencies. This is where exchange tool like Req come in, which allow easy and simple exchange of currencies.
  1. Cryptonex: Fiat and currency exchange between various blockchain services, similar to REQ.
  2. QASH: Qash is used to fuel its liquid platform which will be an exchange that will distribute their liquidity pool. Its product, the Worldbook is a multi-exchange order book that matches crypto to crypto, and crypto to fiat and the reverse across all currencies. E.g., someone is selling Bitcoin is USD on exchange1 not owned by Quoine and someone is buying Bitcoin in EURO on exchange 2 not owned by Quoine. They turned it on to test it a few months ago for an hour or so and their exchange was the top exchange in the world by 4x volume for the day because all Worldbook trades ran through it. Binance wants BNB to be used on their one exchange. Qash wants their QASH token embedded in all of their partners.
  3. Kyber: network Exchange between cryptocurrencies, similar to REQ. Features automatic coin conversions for payments. Also offers payment tools for developers and a cryptocurrency wallet.
  4. Achain: Building a boundless blockchain world like Req .
  5. Centrality: Centrality is a decentralized market place for dapps that are all connected together on a blockchain-powered system. Centrality aims to allow businesses to work together using blockchain technology. With Centrality, startups can collaborate through shared acquisition of customers, data, merchants, and content. That shared acquisition occurs across the Centrality blockchain, which hosts a number of decentralized apps called Scenes. Companies can use CENTRA tokens to purchase Scenes for their app, then leverage the power of the Centrality ecosystem to quickly scale. Some of Centrality's top dapps are, Skoot, a travel experience marketplace that consists of a virtual companion designed for free independent travelers and inbound visitors, Belong, a marketplace and an employee engagement platform that seems at helping business provide rewards for employees, Merge, a smart travel app that acts as a time management system, Ushare, a transports application that works across rental cars, public transport, taxi services, electric bikes and more. All of these dapps are able to communicate with each other and exchange data through Centrality.
  6. Bitshares: Exchange between cryptocurrencies. Noteworthy are the 1.5 second average block times and throughput potential of 100,000 transactions per second with currently 2,400 TPS having been proven. However, Bitshares had several Scam accusations in the past.
  7. Loopring: A protocol that will enable higher liquidity between exchanges and personal wallets by pooling all orders sent to its network and fill these orders through the order books of multiple exchanges. When using Loopring, traders never have to deposit funds into an exchange to begin trading. Even with decentralized exchanges like Ether Delta, IDex, or Bitshares, you’d have to deposit your funds onto the platform, usually via an Ethereum smart contract. But with Loopring, funds always remain in user wallets and are never locked by orders. This gives you complete autonomy over your funds while trading, allowing you to cancel, trim, or increase an order before it is executed.
  8. ZRX: Open standard for dapps. Open, permissionless protocol allowing for ERC20 tokens to be traded on the Ethereum blockchain. In 0x protocol, orders are transported off-chain, massively reducing gas costs and eliminating blockchain bloat. Relayers help broadcast orders and collect a fee each time they facilitate a trade. Anyone can build a relayer.

Market 6 - Gaming

With an industry size of $108B worldwide, Gaming is one of the largest markets in the world. For sure, cryptocurrencies will want to have a share of that pie.
  1. Storm: Mobile game currency on a platform with 9 million players.
  2. Fun: A platform for casino operators to host trustless, provably-fair gambling through the use of smart contracts, as well as creating their own implementation of state channels for scalability.
  3. Electroneum: Mobile game currency They have lots of technical problems, such as several 51% attacks
  4. Wax: Marketplace to trade in-game items

Market 7 - Misc

There are various markets being tapped right now. They are all summed up under misc.
  1. OMG: Omise is designed to enable financial services for people without bank accounts. It works worldwide and with both traditional money and cryptocurrencies.
  2. Power ledger: Australian blockchain-based cryptocurrency and energy trading platform that allows for decentralized selling and buying of renewable energy. Unique market and rather untapped market in the crypto space.
  3. Populous: Populous is a platform that connects business owners and invoice buyers without middlemen. Furthermore, it is a peer-to-peer (P2P) platform that uses blockchain to provide small and medium-sized enterprises (SMEs) a more efficient way to participate in invoice financing. Businesses can sell their outstanding invoices at a discount to quickly free up some cash. Invoice sellers get cash flow to fund their business and invoice buyers earn interest.
  4. Monacoin: The first Japanese cryptocurrency. Focused on micro-transactions and based on a popular internet meme of a type-written cat. This makes it similar to Dogecoin. Very niche, tiny market.
  5. Revain: Legitimizing reviews via the blockchain. Interesting concept, though market not as big.
  6. Augur: Platform to forecast and make wagers on the outcome of real-world events (AKA decentralized predictions). Uses predictions for a “wisdom of the crowd” search engine. Not launched yet.
  7. Substratum: Revolutionzing hosting industry via per request billing as a decentralized internet hosting system. Uses a global network of private computers to create the free and open internet of the future. Participants earn cryptocurrency. Interesting concept.
  8. Veritaseum: Is supposed to be a peer to peer gateway, though it looks like very much like a scam.
  9. TRON: Tronix is looking to capitalize on ownership of internet data to content creators. However, they plagiarized their white paper, which is a no go. They apologized, so it needs to be seen how they will conduct themselves in the future. Extremely high market cap for not having a product, nor proof of concept.
  10. Syscoin: A cryptocurrency with a decentralized marketplace that lets people buy and sell products directly without third parties. Trying to remove middlemen like eBay and Amazon.
  11. Hshare: Most likely scam because of no code changes, most likely pump and dump scheme, dead community.
  12. BAT: An Ethereum-based token that can be exchanged between content creators, users, and advertisers. Decentralized ad-network that pays based on engagement and attention.
  13. Dent: Decentralizeed exchange of mobile data, enabling mobile data to be marketed, purchased or distributed, so that users can quickly buy or sell data from any user to another one.
  14. Ncash: End to end encrypted Identification system for retailers to better serve their customers .
  15. Factom Secure record-keeping system that allows companies to store their data directly on the Blockchain. The goal is to make records more transparent and trustworthy .

Market 8 - Social network

Web 2.0 is still going strong and Web 3.0 is not going to ignore it. There are several gaming tokens already out there and a few with decent traction already, such as Steem, which is Reddit with voting through money is a very interesting one.
  1. Mithril: As users create content via social media, they will be rewarded for their contribution, the better the contribution, the more they will earn
  2. Steem: Like Reddit, but voting with money. Already launched product and Alexa rank 1,000 Thumbs up.
  3. Rdd: Reddcoin makes the process of sending and receiving money fun and rewarding for everyone. Reddcoin is dedicated to one thing – tipping on social networks as a way to bring cryptocurrency awareness and experience to the general public.
  4. Kin: Token for the platform Kik. Kik has a massive user base of 400 million people. Replacing paying with FIAT with paying with KIN might get this token to mass adoption very quickly.

Market 9 - Fee token

Popular exchanges realized that they can make a few billion dollars more by launching their own token. Owning these tokens gives you a reduction of trading fees. Very handy and BNB (Binance Coin) has been one of the most resilient tokens, which have withstood most market drops over the last weeks and was among the very few coins that could show growth.
  1. BNB: Fee token for Binance
  2. Gas: Not a Fee token for an exchange, but it is a dividend paid out on Neo and a currency that can be used to purchase services for dapps.
  3. Kucoin: Fee token for Kucoin

Market 10 - Decentralized Data Storage

Currently, data storage happens with large companies or data centers that are prone to failure or losing data. Decentralized data storage makes loss of data almost impossible by distributing your files to numerous clients that hold tiny pieces of your data. Remember Torrents? Torrents use a peer-to-peer network. It is similar to that. Many users maintain copies of the same file, when someone wants a copy of that file, they send a request to the peer-to-peer network., users who have the file, known as seeds, send fragments of the file to the requester. The requester receives many fragments from many different seeds, and the torrent software recompiles these fragments to form the original file.
  1. Gbyte: Byteball data is stored and ordered using directed acyclic graph (DAG) rather than blockchain. This allows all users to secure each other's data by referencing earlier data units created by other users, and also removes scalability limits common for blockchains, such as blocksize issue.
  2. Siacoin: Siacoin is decentralized storage platform. Distributes encrypted files to thousands of private users who get paid for renting out their disk space. Anybody with siacoins can rent storage from hosts on Sia. This is accomplish via "smart" storage contracts stored on the Sia blockchain. The smart contract provides a payment to the host only after the host has kept the file for a given amount of time. If the host loses the file, the host does not get paid.
  3. Maidsafecoin: MaidSafe stands for Massive Array of Internet Disks, Secure Access for Everyone.Instead of working with data centers and servers that are common today and are vulnerable to data theft and monitoring, You can think of SAFE as a crowd-sourced internet. It’s an autonomous network that automatically sets prices and distributes data and rents out hard drive disk space with a Blockchain-based storage solutions.When you upload a file to the network, such as a photo, it will be broken into pieces, hashed, and encrypted. Then, redundant copies of the data are created as well so that if someone storing your file turns off their computer, you will still have access to your data. And don’t worry, even with pieces of your data on other people’s computers, they won’t be able to read them. You can earn MadeSafeCoins by participating in storing data pieces from the network on your computer and thus earning a Proof of Resource.
  4. Storj: Storj aims to become a cloud storage platform that can’t be censored or monitored, or have downtime. Your files are encrypted, shredded into little pieces called 'shards', and stored in a decentralized network of computers around the globe. No one but you has a complete copy of your file, not even in an encrypted form.

Market 11 - Cloud computing

Obviously, renting computing power, one of the biggest emerging markets as of recent years, e.g. AWS and Digital Ocean, is also a service, which can be bought and managed via the blockchain.
  1. Golem: Allows easy use of Supercomputer in exchange for tokens. People worldwide can rent out their computers to the network and get paid for that service with Golem tokens.
  2. Elf: Allows easy use of Cloud computing in exchange for tokens.

Market 12 - Stablecoin

Last but not least, there are 2 stablecoins that have established themselves within the market. A stable coin is a coin that wants to be independent of the volatility of the crypto markets. This has worked out pretty well for Maker and DGD, accomplished through a carefully diversified currency fund and backing each token by 1g or real gold respectively. DO NOT CONFUSE DGD AND MAKER with their STABLE COINS DGX and DAI. DGD and MAKER are volatile, because they are the companies of DGX and DAI. DGX and DAI are the stable coins.
  1. DGD: Platform of the Stablecoin DGX. Every DGX coin is backed by 1g of gold and make use proof of asset consensus.
  2. Maker: Platform of the Stablecoin DAI that doesn't vary much in price through widespread and smart diversification of assets.
  3. USDT: is no cryptocurrency really, but a replacement for dollar for trading After months of asking for proof of dollar backing, still no response from Tether.
EDIT: Added a risk factor from 0 to 10. Significant scandals, mishaps, shady practices, questionable technology, increase the risk factor. Not having a product yet automatically means a risk factor of 6. Strong adoption and thus strong scrutiny or positive community lower the risk factor.
EDIT2: Added a subjective potential factor from 0 to 10, where its overall potential and a small or big market cap is factored in. Bitcoin with lots of potential only gets a 9, because of its massive market cap, because if Bitcoin goes 10x, smaller coins go 100x.
