Some of you might recall recall our initial facepalm failed launch about 3 months ago (post-mortem here
). Well, we're back--this time with an audit and some new features. This version of DAIHard should should die a little harder this time ;)
After shopping around a bit in the auditor space, we decided to go with Adam Dossa--the very same Adam Dossa that actually found our launch vulnerability and responsibly disclosed it to us! You can see his report here
. By the way, Adam has been a gem: friendly, professional, timely, and flexible. Definitely keep him in mind if you need an audit!
Following is an updated version of our original launch post
. If you've already read that, you might want to skip to the heading What's New in v0.9.2
. Or you can go straight to the app
or go to our info site
for more info! Here is a legitimate concern most of us are familiar with:
To enter or exit the crypto economy, we rely on centralized exchanges such as Coinbase, which track their users, impose limits, and are tightly coupled to their jurisdiction and its banking system. And for all we know, any day now regulations could start tightening these controls further (*we've actually seen some of this play out in the two months since our first launch post). In light of this, can we say in any meaningful sense that crypto is anonymous, limtiless, borderless, immune to regulation, and (most importantly) unstoppable? To really address this concern, we need a completely decentralized gateway between fiat and crypto: something that extends the benefits of crypto to the very act of moving between the old and new economies. But the design of such a platform is far from obvious.
(Localethereum comes close, but as discussed under Unkillable, it doesn't quite cut it. And Bisq is decentralized, but has significant UX hurdles.)
We believe we've found a solution. We are proud to present:
DAIHard v0.9.2 - Almost Definitely Not Broken This Time If you want to jump right in, we recommend first watching our latest usage demo (7 min), then diving in and giving it a shot with a small amount of Dai. (Try it on Kovan first if mainnet is too scary!)
DAIHard extends many of the promises of crypto (borderless, anonymous, limitless, unstoppable) into the exchange mechanism itself, allowing anyone, anywhere to bypass centralized exchanges and the control they impose.
More concretely, DAIHard is a platform, run on smart contracts, for forming one-off crypto/fiat exchanges with other users, in which:
Again, our latest usage demo (7 min) shows this process in action.
- The method of fiat transfer is open-ended, but agreed upon up-front (for example: bank transfer, cash handoff, transfer of online credit, cash drop...).
- You and the counterparty can communicate via end-to-end encrypted chat to coordinate the fiat transfer (i.e. communicate bank account number or reveal a cash drop location).
- Crucially, in the last phase, the Seller can choose to burn the Dai instead of releasing it to the Buyer (but he can't get it back). This credible threat of burn is what makes the platform reliable in the absence of a centralized group of arbitrators or moderators. For more on this see the DAIHard Game Theory medium article (10 min read).
You Need either xDai, or both Dai and Ether, to Use The Tool (At Least For Now) If you want to buy Dai on DAIHard, you must already have Dai--1/3 of the amount you want to purchase--to put up as a burnable deposit. For example, if you only have 10 Dai now, you can only commit to buying 30 Dai, and must complete that trade before using the newly bought Dai to open up a bigger offer (for up to 120 Dai that time).
Most tragically of course, this means that if you don't already have some crypto, you can't use this tool to get crypto--this is why we avoid calling DAIHard an onramp specifically. This comes from the fact that both parties must have "skin in the game" for the game theory to work, and a smart contract can only threaten to burn crypto.
We have some ideas on how to address this drawback in the not-too-distant future, which we'll write about soon. For now it's time to launch this thing and get some users!
Dangerous and Scary To Use In rare cases, a user may have to burn Dai and face a loss on the entire trade amount. The necessity of this ever-present risk is explained in detail in DAIHard Game Theory.
However, a cautious, rational user can gather information (possibly via our [subreddit](daihard)!) about how people have used the tool, successfully and unsuccessfully. They can then create a buy or sell offer with wisely chosen settings based on what has worked for others. Other cautious, rational users can find this offer and commit to the trade if they dare. We expect the vast majority of committed trades should involve rational, cautious users, and should therefore resolve happily.
Still, inevitably there will be sloppy trades that result in burns. As the tool is used, we'll be keeping a close eye on the frequency of burns and keeping you guys updated (perhaps via a "System Status" utility similar to the one found on MakerDao's explorer). In the end, though, we expect the risk in using DAIHard to be comparable to the risk of using any exchange or DNM: ever-present but low enough for the platform to be useful as whole.
So, while DAIHard will never shut down and can't perform an exit scam, the bad news is it's not risk-free. Users will have to approach DAIhard with the same level of caution they would with any new exchange (albeit for different reasons and with a different approach).
So what's the good news?
The Good News While these drawbacks are significant, they enable some remarkable features that no other crypto/fiat exchange mechanism can boast.
Unkillable (Correction: Bisq seems to have a decentralized arbitration system)
We are aware of no other crypto/fiat exchange platform that is truly unkillable.
Bisq and localethereum comes close, but both localethereum relies on centralized processes of arbitration. This means their fraud-and-scam-prevention system can be sued, jailed, or otherwise harrassed--and if that part stops working, it doesn't matter how decentralized the rest of the system was.
DAIHard, in contrast, gives the users the power to police and punish each other, via the aforementioned credible threat of burn. This is simple game theory, and the rules of this game are etched permanently into the DAIHard Factory and Trade contract code: impervious to litigation, regulation, and political pressure.
This Factory contract has no owner and no suicide or pause code. It cannot be stopped by us or anyone else.
Like Toastycoin, this thing was immortal the moment it was deployed (even more immortal than RadarRelay, for example, which does rely on an ownership role). Both DAIHard and Toastycoin (and probably whatever we build next) will last for as long as a single Ethereum node continues mining, and it will remain easy to use as long as someone can find the HTML/JS front-end and a web3 wallet.
(The HTML/JS front-end (built in Elm, by the way, with the lovely elm-ethereum!) is currently hosted on Github pages, which is centralized--but even if Github takes down the page and deletes the code, it's a minor step to get the page hosted on IPFS, something that is on our near-term roadmap in any case)
No KYC, No Limits It's smart contracts all the way down, so DAIHard never asks any nosy questions--if you have Metamask or some other web3 wallet installed and set up, with some ETH and Dai (or just xDai), you can immediately open or commit to a trade. You don't even need a username!
(In fact, we're so inclusive, even machines are allowed--no CAPTCHA here!)
You're limited only by the collateral you put up, so if you have 10,000 Dai you could open up a buy offer for 30,000 Dai (or a sell offer for 10,000 Dai) right now.
We do reccommend trying the tool out first with a small amount of Dai... But we're not your mom! Do what you want!
Borderless It simply doesn't matter where you are, because DAIHard doesn't need to interface with any particular jurisdiction or payment system to work. DIAHard works by incentivizing people (or robots?) to navigate the particular real-world hurdles of bank transfers, cash drops, or other fiat transfer methods. These incentives work whether you're in America, Zimbabwe, or the Atlantic; they work whether the fiat is USD, EUR, ZAR, seashells, or Rai Stones; and they work whether your counterparty is a human, an organization, a script, or a particularly intelligent dog with Internet access.
Any Fiat Type, and Highly Customizeable Here are some examples of the types of trades you might create or find on DAIHard.
As the DAIHard community grows, users will doubtless find much more creative ways to use the system, and we will discover together which types of trades are reliable and which are more risky. Because users can set their own prices and phase timeout settings, we expect the risky trades to charge a premium or have longer time windows, while the reliable ones rapidly multiply at close to a 1:1 price ratio, with quick turnaround times.
- Sell 5 xDai for $5 USD, sent via TransferWise.
- Sell 200 Dai for $180 USD, granted they bring the cash to you by tomorrow afternoon in Central Park, NYC.
- Buy 20 Dai with a $30 gift card for Amazon AWS that you were never going to use.
- Sell 20 Dai in exchange for a $20 Steam game.
- While in Vietnam, sell 200 Dai to someone for €180 anytime in the next two weeks, provided they deposit it into your German bank account.
- While in Germany, sell 20 Dai to someone in exchange for them refilling your pre-paid Vietnamese phone plan.
- Buy 30 Dai for 8,000 ZWD, which you deliver anonymously by cash drop in Hume Park, Bulawayo, sometime within the next month. (If there's one place that could use unstoppable access to crypto, it's Zimbabwe, and you don't need to take our word for it.)
- Buy 500 Dai for $550 via PayPal, but wait 3 weeks for before the Dai is released (so the paypal transaction can't be reversed).
Extensible (with profit) by Third Parties Not satisfied with our interface? Do you have some nifty idea for how to display and organize user reputation? Or maybe some idea for how trades could be chained togeher? Maybe you'd like to design a notification system for DAIHard? Maybe you just want a different color scheme!
Well, you won't need our permission to do any of this. Any tool that watches the same Factory contract will share the pool of trades, regardless of which tool actually creates the trade. This means we don't even have to fight over network effects!
And if you look closely at our fee structure, you might notice that only half of the 1% DAIHard fee is "hardcoded" into the Factory contract. The other half is set and charged by our interface. What does this mean for you? If you go out and make a better interface, you can essentially replace half of our 1% fee with your own fee--it's up to you whether it's smaller or larger than the replaced 0.5%.
The reason for this is to explicitly welcome other developers to extend what we've built. For as long as our team is the only one improving the platform, a threat to us is a threat to future upgrades. But if others begin extending the DAIHard platform too, then DAIHard will not only be unstoppable as it is today, but also grow unstoppably.
(For Real This Time) This Is a Big Fucking Deal DAIHard is a turning point in crypto and a breakthrough in decentralized markets, and is an irreversible augmentation of the Ethereum platform.
What we've built is a gateway to crypto completely devoid of centralized components--rendering entry and exit to crypto unkillable, flexible, borderless, and private. Centralized exchanges, and the control they impose, can now be bypassed by anyone with Dai and a web3 wallet.
What's New in v0.9.2 There have been many changes made since our first failed launch, but there are two rather important ones: xDai support and reputation tools.
xDai support DAIHard is now operational on xDai, a sidechain whose native token (xDai) is pegged to the Dai (and therefore $1). Add the xDai network to your Metamask (or just install Nifty Wallet), then switch to the xDai network in your wallet, to try it out. xDai has some pretty incredible benefits, compared to vanilla Ethereum:
- Price: On xDai, a single DAIHard trade costs on the order of $0.01 to run start-to-finish, rather than the accumulated $2.40 (with the best-case-scenario 1gwei gas price) you'll spend on vanilla Ethereum.
- Speed: Trade actions mine much faster, and don't require ERC20 'approve' transactions, making the whole process way snappier.
- Gas priced in xDai: the main benefit here is that you only need one token (xDai) rather than two (Dai and Eth). Also, it's just nice having the gas cost expressed in (essentially) USD!
Reputation tools We now have a few reputation tools. First, on any open trade, there is a widget showing the number of releases, aborts, and burns the given address has been involved in as that role (buyer or seller). Clicking on this expands the widget to show more detailed information, and also provides a link to a page that lists each trade this user has been or is involved in.
What's next? We have tons of ideas on how to improve the product--too many, in fact, to commit to any before we get a good chunk of user feedback. Here are some of our favorite ideas:
Near-Term, Smaller Features
- Lots of usability improvements.
- A "System Status" utility similar to the one found on MakerDao's explorer).
- Marketplace / My Trades rework.
- A "QuickTrade" page, offering Trade Templates as an alternative to the current Create Offer page.
Big Exciting Features
- Bootstrapping people with no DAI via other mechanisms and community outreach.
- Partial commits to trades. eg. Place a 10,000 DAI trade and allow it to be picked up in blocks larger than 500 DAI at a time.
- More chains, get this thing working on Bitcoin via Rootstock, on Ethereum Classic and Binance Chain.
Stay Informed! A lot of the above features will be prioritized more clearly as we get user feedback, and we will be posting fairly frequent updates and articles on our info site. If you don't want to miss anything, note the subscribe widget and sign up!
How I see the top 10 currencies on CoinMarketCap.com
1 Bitcoin is the number one cryptocurrency, with all the hype and all the press. I do not see any coin overtaking it in the near future. Probably never.
- Bitcoin Gold IS better than bitcoin in MANY ways.
A) Bitcoin Gold allows for GPU mining on people’s home computers and it is ASIC resistant, which makes for a more decentralized coin. (One of the founding principles of bitcoin, which has fallen by the wayside with Chinese asic (such as BITMAIN) controlling most of the mining market and allowing it to pull all sorts of shenanigans. B) Bitcoin transactions have become slooooooooow! (Bitcoin GOLD is much faster) C) Bitcoin transactions are PRICEY! You can't even send someone $10 worth of bitcoin because the fees would eat the entire transaction. This is why STEAM dropped bitcoin. The fees have become ridiculously high (see miners controlling the market above as to reasons for this) Bitcoin Gold has lower fees. D) The network for bitcoin can be VERY unstable. Whenever Bitmain wants to move the miners over to it's own fraud coin, bitcoin cash, they slow the market and delay transactions. This should be seen for what it is: an ATTACK on bitcoin. With all that said, bitcoin still carries on and the price continues to climb! It remains #1 in marketcap.
2 in marketcap is Etherium. People love to remind you that Microsoft is backing Etherium. Yeah, but guess what. Etherium's network is an absolute mess!!
Hundreds of millions of coins have been lost because of a "bug". WOW. The 44billion dollar Ether network was brought to its knees by Crypto Kittie, a digital cat child’s app that uses Etherium contracts to trade digital pussies. Etherium shouldn't be number 2. Not until they can create a stable network. Who knows what will bring it down next? Digital dogs?
3 Bitcoin Cash. This currency is a fraud. It merely exists to allow Bitmain to use asic boost, to give it an advantage mining coins. Once Segwit went into place on bitcoin they could no longer use asic boost and lost their advantage so they forked bitcoin for greed. They tried to take a bunch of miners with them and force everyone who wants to buy an antminer to pay for them in Bitcoin Cash, driving up BCC and trying to take down BTC. This is a fraud currency and everyone should ignore it, and let it die on the side of the road like the diseased rodent it is.
4 Litecoin This is a great coin. It is more stable than every coin above it. The network is reliable and the transactions are fast. As if that were not enough, the fees are ridiculously low. So low that they have attracted STEAM, who just dropped bitcoin, to allow people to purchase on their store with Litecoin.
This should be the number 2 coin, in my opinion. (only because nothing is going to dethrone Bitcoin.)
5 Ripple If you have ever invested in ripple, and thought the price was going to go up and was surprised how it suddenly came crashing down, well you are not imagining things and you are not alone. The price on this coin is manipulated.
Don’t be me wrong, Ripple is a useful coin with good tech behind it. Fast transactions, good scalability and low fees, but this coin is used by banks to transfer fund between them. They do not want to the value to go up because that would make the fees larger. This “global “token is mainly traded on Korean exchanges. This coin was not designed to be a holder of value, so if you are looking to invest, I would stay away from Ripple. Anything over 25 cents is risking a sudden plunge. I’m amazed to see it at 36 cents.
6 IOTA - I love IOTA. What a great coin with a great team behind it. The network (Tangle) is very advanced and they love to brag about how they are an improvement over bitcoin. The people involved in IOTA tend to be very passionate and haters of blockchain.
The problem? Well, their wallets don’t even work! You can buy it on Binance, but you can’t even withdraw it because they have so many problems trying to get a wallet to be stable. For a coin that suddenly shot up to $5 (I rode a lot of that up and jumped out) on the news that they were working with Samsung, Microsoft and others on an information sharing network, I would think they could get their transaction network up and running so people can keep coins reliably in their wallets and get them off exchanges.
7 DASH One of a kind. The network funds itself. Unheard of. It’d decentralized with Masternodes that vote on how to spend the budget. (masternodes controlling the future don’t sound decentralized to me, but I digress) They claim instant transactions and privatesend (wasn’t this darksend?) This used to be XCoin in Jan 2014. 10 days later the core dev team changed the name to Darkcoin. Later they changed the name to DASH (not to be confused with Dashcoin, which is exactly what many people do… get confused.)
Some people would say there is a dark side to Dash coin, but to each their own.
8 NEM My first question is if the currency is called NEM, why is the symbol XEM??? NEM codes its own blockchain making it efficient and stable. If you hold 10,000 XEM, you can harvest(?) which incentivizes people to hold, which will inflate the price. (HODLING is the main reason bitcoin goes up in price. If everyone were day trading it can you imagine the volatility? When you limit the supply and there is still a high demand the price must go up. Simple as that.) NEM (or XEM) is not discussed very much and is not widely known. This is odd considering its high market cap (top 10 baby) and its solid tech. NEM (like bitcoin gold) needs some good marketing.
#9 Monero This is a PRIVATE COIN, untraceable currency. This coin has a purpose, and that purpose is protecting the privacy of the users of it. You can send and receive Monero without knowing who you sent or received coin from. This coin will increase in value as demand for privacy will only continue to increase and this is the world’s number one privacy coin (sorry dash). Some people may have ethical reasons to not want to invest in a coin that may be used for all manner of shady dealings online. That’s up to you to decide. Are you against fiat cash? For the most part cash is untraceable too, and people use it for all sorts of shady things, but people also use it for plenty of good things.
10 Bitcoin Gold Finally a version of bitcoin I can mine on my computer at home! YEAH!!! Bitcoin is SUPPOSED to be decentralized, and this is the ONLY flavor of bitcoin that lives up to that. It’s the same block interval and block size as bitcoin, but it updates difficulty on every block and prevents ASIC’s by using POW Equihash so people can mine on GPU’s at home.
As I mentioned above, Bitcoin Gold has faster transfers with lower fees and the network is not able to be manipulated by companies such as Bitmain, because large ASIC farms have no control over this network. Some mysterious forces (I wonder who?) attacked Bitcoin Gold when it first launched, with DDOS attacks and faking wallets. Despite the rough start, bitcoin gold has been widely accepted at 25 exchanges including Bittrex, HitBTC, Bitfinex, Binance and Yobit! It has even found a home in hardware wallets like Trezor and Ledger. You can use Coinomi on your phone too. http://amzn.to/2AeoyMI

THE TOP 5 COINS FOR ME: 1) Bitcoin (obviously) 2) Litecoin 3) Etherium (Because of the hype) 4) Monero 5) Bitcoin Gold Honorable mentions: IOTA and NEM
