Vitalik Buterin Just Proposed Killing DeFi Liquidations. Builders Are Already Moving.




 Vitalik Buterin dropped a research post on June 1 that might be the most significant DeFi architecture proposal in years. Less than a week later, a developer had already deployed a working version on Base and completed a full on-chain settlement cycle. The speed of that response is not normal.

The proposal centers on replacing collateralized debt positions, the foundation of most DeFi protocols today, with options contracts. Under the current model, users lock crypto as collateral, borrow against it, and face forced liquidation when prices move too sharply. Buterin's proposed system would replace that with a two-token structure: P and N, both minted from one ETH, each holding different sides of price exposure at a set strike and maturity date.

The structural upside is significant. No forced liquidations. No real-time oracle dependency. Settlement expressed as a simple asset transfer rather than a price lookup. A developer named mmchougule ran the full P/N lifecycle on Base using an ETH/USDC pair and showed the exercise transaction executes atomically.

But the trade-offs are real too. Users would need to actively rebalance their positions as prices move, and rebalancing costs money. Every trade incurs slippage, especially during the volatile conditions this system is designed to handle. Buterin himself acknowledged rebalancing slippage is one of the biggest unsolved challenges of the design.

Vitalik also issued a clear warning: anything moving toward mainnet deployment needs formal verification first. He named Vyper and Fricoben of LFG Labs as potential auditors. That instruction matters because at least three independent implementations are already in motion, including a testnet version at testnet.cleave.market.

This is early-stage research. But the builder response suggests the proposal is touching something real in how DeFi developers think about liquidation risk. Whether options-based synthetic assets ever reach production, the conversation around oracle dependency and forced liquidations just shifted.

For the full breakdown of how the P/N mechanism works, the on-chain implementation details, and what Vitalik flagged before any of this reaches mainnet, the complete article is on CryptoNewsLive.org.

Ripple Is Building XRPL's Defense Against Quantum Computing, and the Clock Is Already Running

Image
  Ripple has released a detailed plan to protect the XRP Ledger from quantum computing threats, and the timeline it has set is not aspirational. The target is full post-quantum cryptography readiness by 2028, with active work already underway in 2026. The roadmap runs four phases. The first is an emergency contingency for a scenario where quantum computers break classical cryptography ahead of schedule. Ripple calls this Q-Day readiness. In that scenario, the XRP Ledger would enforce a hard network shift, stopping classical public-key signatures and requiring users to migrate to quantum-safe accounts. The second and third phases cover 2026. Testing begins on NIST-recommended post-quantum algorithms under real XRPL workload conditions. Performance, storage, and bandwidth costs all get measured. Then hybrid deployment begins on Devnet, running quantum-resistant signatures alongside existing ones before anything touches the live network. Project Eleven, an organization working on cr...

Hoskinson Just Said Everything Nobody Else Will Say About Crypto in 2026

Image
  Charles Hoskinson spent over an hour on the O Show with host Wendo in April 2026 and covered ground that most crypto founders avoid in public interviews. The Midnight Network mainnet went live on March 31 with nine institutional node operators including Google Cloud, MoneyGram, Worldpay, Telegram, Vodafone's Pairpoint, eToro, Bullish, Blockdaemon, and Shielded Technologies. That alone is a headline. But it was not the most important thing he said. The AI agent argument is where this interview breaks from the usual. His position is that zero-knowledge proofs are not primarily a privacy feature. They are the only mechanism by which AI agents can verify each other's behavior. When an autonomous agent is managing your funds across multiple blockchains while you sleep, it needs mathematical proof infrastructure underneath it to constrain what it can do, protect your data without exposing it, and settle value in real time without a middleman. Midnight is being built for that future...

Everclear Is Gone and the $500M Volume Story Should Worry Every DeFi User

Image
 Everclear, the cross-chain settlement protocol that processed $500M in monthly volume, announced this week that it is shutting down. The Foundation and Labs entities are winding down operations. The product UI is already offline. The chain is non-operational. This is not a rug pull. It is something arguably more instructive: a protocol that built real volume, real technology, and real partnerships, and still could not survive. The team's own explanation makes it plain. Users were highly price-sensitive. The solver-based model that Everclear was built around never developed the revenue depth it needed, even with hundreds of millions of dollars flowing through the system monthly. A B2B2C pivot was attempted. Major industry names signed on. But the timelines to go live were longer than the runway the team had left. Acquisition talks were explored. They did not succeed. The CLEAR token has lost more than 52% of its value in seven days. A potential buyback is being explored in the ...
