Bitcoin developers have introduced BIP-361, a proposal designed to safeguard wallets against future quantum-computing risks, specifically targeting the protection of hundreds of billions of dollars in cryptocurrency from potential vulnerabilities, with the Bitcoin community and investors closely watching the development of this proposal.
Quantum Computing Vulnerabilities and BIP-361
The proposal, officially designated on February 11, 2026, and authored by Jameson Lopp alongside five collaborators, carries the formal designation “Post Quantum Migration and Legacy Signature Sunset,” aiming to identify and protect at-risk holdings before quantum threats materialize, thereby ensuring the security of the Bitcoin market and its investors, with the price of Bitcoin potentially being impacted by the success or failure of this proposal.
According to the proposal, a Bitcoin wallet becomes susceptible to attack when its public key appears on the blockchain ledger, and sufficiently advanced quantum computers could theoretically reverse-engineer these public keys to derive the corresponding private keys, granting unauthorized access to funds, highlighting the need for a robust blockchain security system to prevent such attacks and protect investors' assets, with the crypto community awaiting the implementation of BIP-361.
Market Impact and Investor Concerns
By March 1, 2026, over 34% of Bitcoin’s total supply had public keys visible on-chain, representing a substantial risk, and the proposal would block new BTC transfers to addresses considered vulnerable to quantum attacks, and phase out legacy signature schemes over a period of time, aiming to mitigate the risks associated with quantum computing and ensure the long-term security and stability of the Bitcoin market, with investors and the crypto community closely monitoring the development and implementation of BIP-361.
