Stablecoins: A Holy Grail in Digital Currency

This article is a little old, but, still a very good overview of the challenges and opportunities!

A global currency with no central bank and low volatility may be a key component of the decentralized web

One of the main characteristics of digital currencies that the mainstream media has focused on is volatility. While the volatility of Bitcoin has decreased significantly since it launched in 2009, it is still not a good unit of account or a stable store of value. Look no further than the price of BTC and ETH over the past month (BTC price moved over 10% in a day and ETH moved over 20% in a day several times).

What if the volatility of a a digital currency could be minimized by a decentralized autonomous organization (DAO) with no central authority? This is the promise of an emerging category of digital assets called stablecoins.

A stablecoin is an asset that has price stability characteristics that make it suitable for short-term and medium-term use as a unit of account and store of value. The US dollar is the best example of a stablecoin in the world of fiat currencies. While USD does offer relatively low volatility for those that want a reliable unit of account and store of value, it doesn’t offer user control because it’s controlled by the Federal Reserve Bank and requires reliance on the US banking system for significant commercial use. User control and minimized volatility is a holy grail in not just digital currencies but currencies broadly. The Maker project is seeking to reach this holy grail by creating the first viable stablecoin: the dai.

Meet Maker

The dai does not exist yet and is not much more than a vision. But the groundwork is currently being laid for a stablecoin that could bring millions of more people into the blockchain ecosystem.

In 2015, Rune Christensen published the white paper that describes the Dai Credit System, a complex organizational structure designed to create a digital asset with minimized volatility and no central bank. Since then, Rune and the decentralized autonomous organization known as Maker issued MKR tokens and built a lot of the infrastructure required to bring the vision to life, including a decentralized exchange for ERC20 tokens, developer tools for writing smart contracts, and core splitting auction contracts.

The Maker team has significant security work left to do on the smart contracts, but the plan is to launch the dai by the end of 2017. The system the Maker DAO is building is complex but it is inspired by a lot of economic theory. If you’re an econ nerd like myself, you may enjoy the next section. If not, you may want to skip.

Understanding the Dai Credit System

There will be two different tokens in the Dai credit system: Dai (the stablecoin) and MKR (the counter coin). Dai is a free floating currency that derive its value from the fact that it’s backed by collateral (ETH to start, other digital assets later). MKR is a token that derives its value from the fact that it earns stability fees (interest) from the borrower of dai and has an active function in making the whole system work (governance). There are 1 million MKR tokens outstanding currently, but this will fluctuate in the future based on the performance of the system (if good then the total supply will decrease, if bad it will increase).

The tokens have been continuously sold off in small batches by the Dai Foundation. Currently about 55% of the total supply has been distributed, with the foundation still having another 45% for future fundraising.

Another important value proxy to consider in the system is the Special Drawing Right (SDR), which is an international currency basket maintained by the International Monetary Fund (IMF) that has low volatility against all major world currencies. The target price of dai will always be in terms of the SDR.

There are five different types of participants in the Dai Credit System that all play critical roles:

  • Dai borrowers: Dai borrowers create dai by locking up collateral in ETH or other digital assets (which will be voted on by MKR holders). This is known as a collateralized debt position (CDP). A primary initial use case for borrowers is likely to be margin trading (traders can borrow dai by posting ETH as collateral and sell the dai in exchange for ETH to leverage ETH exposure). A borrower that wants their collateral back has to return dai + interest (which gets paid to MKR holders).
  • Dai holders: Holders are individuals or companies that are motivated to use dai as a unit of account or store of value that they control.
  • MKR Holders (Governors): MKR holders play two important roles in the system: they vote on decisions the Maker DAO makes (like what digital assets can be posted as collateral and what features should be prioritized) and they help keep the dai stable (meaning they act as the final backdrop for all collateralized debt positions). When CDPs hit their liquidation ratio (the equivalent of a margin call), new MKR is created and existing MKR holders step up and buy back the assets with DAI and returns to the borrower whatever is left over.
  • Keepers: Keepers are economic agents that are incentivized to contribute to making the system run efficiently. Specifically, they perform two important functions in the system: participating in continuous splitting auctions and market making the dai around the target price.
  • Oracles: Maker needs information about the market price of the dai and its deviation from the target price in order to adjust the deflation rate as well as the market price of the various assets used as collateral for the dai in order to know when liquidations can be triggered. Oracles provide that service in the system.

This is an extremely complex organizational structure with lots of moving parts. Like all blockchain projects, it’s an economic experiment that’s never been tested before and no one knows for sure how the different participants will react and if the system will work as designed. I’m personally excited to see it tested in the wild though.

A decentralized currency with no volatility could ultimately become the backbone of the global economy.

How to learn more


How lambo with stablecoin tho?

Seriously though…a good stable coin in this world would be a GAME changer.


Talked about this twice on


Interesting concept but honestly, way to complicated for me to understand. I’ll probably need to take a while learning it.

There’s an another crypto that aims to be a stablecoin but through a stable growth. MinexCoin aims to have a channel set between the price and aims to have a growth rate similar to the top 10 cryptocurrency. They have a bank that pays interest and the interest rate fluctuates based on market price. The cool thing is that the bank doesn’t hold your fund but simply observes your public key and gives interest based on how long you HODL your coins.

I understand this concept but I’m not sure if it’s economically sound. What’s your input on MinexCoin, @john ?


So the short story is you think they’re too risky? Here’s a good article from Multicoin Capital -


I’m surprised this article hasn’t received more attention from pub members. I like the idea of MKR and stable coins, however I haven’t done fundamental yet. Thanks John and Peter.


I’ve been DCA’ing MKR since I got sick of IOTA’s crappy wallet months ago.

There’s a good article on stablecoins here -


BTC will solve that problem when 99% of people use it. Lack of stability is not a problem solved by technology, but adoption.

Because if there is a 99% adoption, it will be seen as an important store of value or currency. Currencies volumes are trillions of dollars a day. A stock like Apple got a daily volume of about 7 billions $ today and Bitcoin got a 5.5 billions $. They are both considered volatile because they lack volume (BTC is worse because its volume is spread among a lot of exchanges while Apple trade only on one exchange). If you have an order book filled with trillions of dollars on a single exchange, good luck trying to have the price move quickly.

And since when Apple has 99% adoption ? Everybody you know has apple stock ?

Hey @peter I remember one of your concerns with MKR was if the collateral backing it, namely ETH, went to $0 then that could be a problem. MakerDAO plans to introduce multi-collateral Dai and back it with stuff like Digix (Gold) or other non crypto assets that are more stable. See their response below.

I personally believe crypto collateralized stablecoins (Dai/MKR) are better than non-crypto collateralized stablecoins. You can also see below that Vitalik isn’t crazy about Basecoin/Basis, which is a different version of a non-crypto collateralized stabelcoin.

It’s also public info that A16Z and Polychain bought a bunch of MKR for around $300. So they’re expecting Tether to fail and either Dai/MKR to win or Basecoin/Basis. Just some food for thought.
