Stablecoins DeFi Cần Thiết Kế Mạnh Hơn, Vitalik Buterin Nói

Ethereum co-founder Vitalik Buterin says decentralized finance (DeFi) still needs stablecoins that are truly decentralized. According to him, coins that just stay pegged to $1 are not enough. Stablecoins must also survive censorship, oracle problems and incentive failures.

In a statement on January 11, 2026, Buterin pointed out that many stablecoins rely on centralized systems or shared infrastructure. These weaknesses can cause huge problems if they fail.

Stablecoins Need More Than a $1 Peg

Buterin warns that keeping a coin at $1 is not enough to protect users. Stablecoins must continue to work even when systems fail or bad actors attack.

He gave MakerDAO as an example. MakerDAO depends on oracle feeds to set prices. If these feeds are manipulated, it can trigger chain reactions of liquidations and market chaos.

He also said competition for staking yields can reduce demand for stablecoins during market stress. This shows that stablecoins need strong designs that keep them safe in difficult situations.

Risks in Current DeFi Systems

Many current stablecoins use USD benchmarks and shared infrastructure. While this makes them easier to use, it also concentrates risk.

Buterin recommends designs with diversified price indexes and reliable, secure oracles. These features can prevent system-wide crashes.

Reports from CoinDesk and Phemex back this view. They warn that depending on a few price feeds or centralized tools can make DeFi fragile. Spreading risk and rewards across many independent actors helps keep the system safe.

What This Means for Users

DeFi is still new and evolving. Even popular stablecoins can face problems. Users and investors should understand how each coin keeps its value and handles stress.

Strong, decentralized stablecoins would make DeFi safer. They could reduce the chance of sudden crashes and give people more confidence to use digital money.

The Future of Stablecoins in DeFi

Vitalik’s comments highlight the next step for DeFi innovation. Stablecoins that resist failures and attacks will help the entire ecosystem grow.

The focus on strong, decentralized stablecoins is now key to keeping DeFi safe and reliable. Projects that succeed in this area could become the backbone of the crypto world.
