Why NEAR Protocol Just Made the Biggest Blockchain Security Move of 2026




 Most people in crypto are not thinking about quantum computing yet. The threat still feels abstract — something for researchers, not wallet holders. That assumption is getting harder to hold.

On May 6, 2026, Near One CTO Anton Astafiev published a post that changed the tone. Progress on quantum computing has accelerated to the point where timelines the industry assumed were years out have been reached in months. NEAR Protocol responded with a concrete plan rather than a roadmap promise.

The Near One team is adding FIPS-204 (ML-DSA), a NIST-approved lattice-based signature scheme, as NEAR's first post-quantum signing option. Testnet is scheduled to go live before the end of Q2 2026. When it does, any NEAR account holder will be able to rotate their keys to a quantum-safe scheme through a single transaction. No hard fork. No emergency migration. One transaction.

That is only possible because of how NEAR was built. Bitcoin and Ethereum addresses are cryptographically tied to keypairs that quantum computing could eventually crack. NEAR's accounts are not. They are controlled through rotatable access keys, decoupled from any specific cryptographic scheme. The protocol was designed from the beginning to expect cryptography to change.

The hardware wallet problem is harder. Current cold storage devices — including Ledger — do not support quantum-safe signing. Near One is already in talks with manufacturers, but the gap is real. For anyone who relies on a hardware wallet as their main security layer, this is the most urgent part of the story.

NEAR also supports threshold signatures across more than 35 chains. The team working on NEAR Intents is building quantum-safe cross-chain signatures, which would give users from other ecosystems a place to secure assets through NEAR if their home chain is slow to act.

Co-founder Illia Polosukhin confirmed the Q2 timeline and said the protocol was built expecting this exact scenario.

For the full technical breakdown — including the zero-knowledge proof fallback research and the downstream wallet coordination — the complete story is at CryptoNewsLive.org. This is the quantum story the rest of crypto has not taken seriously yet.

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...

: KelpDAO's $292M Bridge Hack Just Broke Aave and Locked Real Lenders Out

Image
  On April 18, 2026, a single forged message on a cross-chain bridge became 2026's largest DeFi exploit. Someone called the lzReceive function on LayerZero's EndpointV2 contract, tricked KelpDAO's bridge into accepting it as a legitimate transfer, and walked away with 116,500 rsETH worth $292 million. That was 18% of rsETH's entire circulating supply, minted on Ethereum mainnet with nothing backing it. The attacker did not stop at the theft. The stolen rsETH went straight into Aave V3 as collateral, and against it, the attacker borrowed approximately $236 million in wrapped ETH. Real funds, borrowed against tokens that had just been fraudulently minted. Aave was left with roughly $280 million in bad debt, frozen rsETH markets on both V3 and V4, and an ETH utilization rate that hit 100%. That last number matters more than it sounds. When ETH utilization on Aave reaches 100%, lenders cannot withdraw. Real WETH suppliers, people who had deposited ETH into Aave's len...
