BIP-361

Bitcoin's vulnerability to quantum computing threats is framed as a governance challenge rather than a technical one. Proposals like BIP-360 and Hourglass aim to mitigate risks, but debates persist over migrating legacy addresses and handling non-migratable coins like Satoshi Nakamoto's holdings.

The article clarifies that soft forks, like the proposed BIP-361, can cause chain splits and incompatibility despite being backward-compatible with old clients. It challenges common misconceptions about hard and soft forks, emphasizing that both can disrupt the blockchain, though soft forks add technical complexity.

The article explores the legal and technical implications of quantum computing breaking Bitcoin's cryptographic security. It highlights BIP-361's proposal to freeze quantum-vulnerable UTXOs and argues classical property law would classify stealing Bitcoin via quantum means as theft, despite Bitcoin's control-based ownership model.

Bitcoin developers have proposed BIP-361, a solution aimed at protecting Bitcoin addresses most vulnerable to seizure via quantum computing attacks. The proposal seeks to freeze these at-risk funds, but its adoption remains uncertain as the community debates its merits.

Adam Back, CEO of Blockstream, advocates for optional quantum-proofing upgrades to Bitcoin, contrasting with BIP-361's proposal for mandatory freezes on quantum-vulnerable Bitcoin. The debate highlights differing approaches to securing Bitcoin against quantum computing threats.
