Vitalik calls for abandoning the US dollar stablecoins! Proposes using "AI combined with prediction markets" to create customized stable assets

According to the latest post released by Vitalik Buterin on the X platform, he believes that the crypto market should move away from reliance on USD stablecoins to ensure true decentralization. He proposes a disruptive idea: abandoning traditional currency concepts and instead using users' local AI (LLM) to analyze daily expenses, and leveraging "prediction market" shares to tailor a personal asset portfolio that maintains purchasing power.
(Background summary: Vitalik praises a new technology he has waited ten years for: the privacy protocol Interfold, which perfectly implements "anonymous on-chain voting" by combining ZK and FHE)

• Returning to essence: people need "price stability"
• Local LLM combined with prediction markets: creating personalized asset portfolios
• A new financial vision of abandoning fiat currency

Ethereum co-founder Vitalik Buterin posted a lengthy article today (2nd) on the X platform, continuing his exploration of synthetic stablecoins from a few months ago. He openly questions: if we are to create a synthetic stablecoin, what should it actually be "stable" against? He straightforwardly states that pegging to the USD is far from ideal.

Vitalik believes that the current crypto market's over-reliance on USD-backed stablecoins, if the entire ecosystem is built on this foundation, will ultimately prevent true decentralization.

Returning to essence: people need "price stability"

Vitalik analyzes that those who want to hold stablecoins ultimately seek "price stability." People have expectations of future expenses and want a guarantee to ensure they will have the ability to pay for these costs when the time comes. However, everyone's lifestyle differs, and the types of expenses they face vary greatly, making it difficult for a single currency to perfectly meet all individuals' real needs.

In the past, there have been many discussions about creating an "ideal stablecoin," such as pricing based on a decentralized global price index. But Vitalik proposes a bolder idea: what if the real solution is to go even further and completely abandon the concept of "currency"?

Local LLM combined with prediction markets: creating personalized asset portfolios

To address this issue, Vitalik proposes a new mechanism that combines artificial intelligence with prediction markets. His concept includes the following core operations:

• Establish classification-based price indices and prediction markets: Create price indices for all major categories of goods and services people purchase (treating different physical goods or services in various regions as different categories), and set up corresponding prediction markets for each category.
• Local AI precise customization: Each user (individual or enterprise) will have a "local large language model (Local LLM)." This AI can deeply understand the user's spending habits and provide a "personalized prediction market share portfolio."
• Guarantee purchasing power: This exclusive asset portfolio will represent the user's expected expenditures over the next N days, thereby achieving true personalized anti-inflation and purchasing power protection.

A new financial vision of abandoning fiat currency

In this futuristic native crypto vision, traditional fiat currency will no longer be necessary. Vitalik summarizes that people can achieve wealth growth by holding stocks, ETH, or other assets; and when they need stability, they can simply hold this "personalized prediction market share" to meet their needs.

This concept-rich discussion not only sparks community attention but also points toward an innovative direction that combines AI development for how the crypto world can realize decentralization and customization in a post-fiat era.
