Vitalik Buterin proposes personalized stablecoin baskets to replace USD pegs

Ethereum co-founder Vitalik Buterin has reposted an earlier proposal he made to ditch the U.S. dollar as the default reference point for stablecoins. He suggests that users hold personalized baskets of prediction market shares tied to their own spending patterns instead.

The proposal by Vitalik follows a trend where more countries are choosing to conduct their trades in non-dollar settlement alternatives. These alternatives have ranged from TradFi proposals such as BRICS currencies to decentralized finance experiments.

What did Vitalik Buterin propose? 

Vitalik Buterin recently reposted an idea he first outlined months earlier on the social media platform X in a longer essay about the future of prediction markets.

Buterin’s central question is simple: “If we’re making a synthetic stable, what should it really be stable WITH RESPECT TO?” 

His answer involves the use of a local large language model (LLM) on each user’s device that would analyze that person’s spending habits and assemble a custom basket of prediction market positions representing a set number of days of expected future expenses. 

Wealth growth would come from holding stocks, ETH, or other assets, while stability would come from the personalized basket.

The proposal also requires that prediction markets be denominated in assets people actually want to hold, whether that is interest-bearing traditional currencies, wrapped equities, or ETH. Buterin argued that non-interest-bearing currencies carry opportunity costs that are too high to serve as the base layer.

Buterin has been vocal about the risks of dollar dependence for months. In January, he said that pegging stablecoins to the dollar ties supposedly decentralized systems to a single national currency’s monetary policy and geopolitical exposure. Over long time horizons, even moderate inflation could erode usefulness, he argued.

Regarding oracle design, Buterin stated that systems governed primarily by token ownership lack natural defenses and must charge their users significant fees to make attacks uneconomical. Blockchains rely on oracle systems to access external price data. If those oracles can be captured by well-funded actors, the entire protocol becomes vulnerable. 

His third issue was that when stablecoins use staked ETH as collateral, the yield earned by locked collateral competes with what stablecoin users could earn elsewhere.

What are the other alternatives to the dollar? 

J.P. Morgan’s global macro research shows that a growing number of energy contracts in commodity markets are being priced in currencies other than the dollar. Central bank reserves held in dollars have also declined over the past two decades.

The Center for International Relations and Sustainable Development reports that Russia now conducts roughly a third of its trade in Chinese yuan. Brazil and China agreed in 2023 to settle trade directly between the real and the yuan, and India purchased a million barrels of oil in rupees that same year.

90% of foreign exchange transactions and 48% of SWIFT payments are still done in dollars, and most crypto users prefer to use dollar-pegged stablecoins for payments and savings. Tether’s USDT accounts for roughly $186.8 billion in circulation, which is more than 60% of the total stablecoin supply. 

The available decentralized alternatives like Ethena’s USDe and Sky Dollar each account for around $6.3 billion, while Dai has contracted to approximately $4.5 billion.
