StarkWare says Bitcoin has completed its first experimental quantum-safe transaction. The test used Bitcoin’s existing rules to protect funds from a potential future quantum attack without requiring a network upgrade.
Bitcoin’s first post-quantum transaction was broadcast this week, Bitcoin Magazine reported. The Sharknet Foundation explained the process at Bitcoin Asia, where it discussed how the transaction was completed without a Bitcoin fork.
Bitcoin researchers propose SHRINCS, a quantum-resistant approval design that could allow larger transaction signatures while preserving more network capacity than existing post-quantum alternatives, according to CoinDesk.
StarkWare said it completed an experimental quantum-resistant Bitcoin transaction on mainnet without a fork. Cointelegraph reported that the test cost up to $200 and required direct submission to a miner.
A new BIP proposes using the SHRINCS signature scheme to make Bitcoin more resistant to quantum-computing threats. Cointelegraph reported the proposal’s publication, while implementation details and the stated trade-off were not provided.
Ethereum developers proposed deposit-contract changes for quantum-resistant staking. The plan would expand validator keys to 8,192 bytes and add a switch to permanently retire the BLS signatures currently in use.
Ethereum developers have drafted a proposal to let validators use quantum-resistant keys for ETH staking and eventually end support for the format currently used. The measure remains an initial proposal, with no implementation timeline provided.
XRP’s 44% rally has brought leverage back to the Binance market, with estimated leverage at its highest since January. Longs outnumber shorts and futures volume exceeds spot trading by more than five times, raising pullback risk.
CryptoQuant says Bitcoin’s 24% rally has turned key indicators bullish and marks the initial phase of a new bull market, while $83,000 remains important and rising profit-taking could fuel near-term turbulence.
