Svmuu News Bitcoin One of the contributors, Jameson Loop, along with other cryptographers, has proposed an initiative that could force Bitcoin holders to migrate their tokens to new post-quantum addresses; otherwise, their tokens will be permanently frozen by the network itself.In this scenario, holders would technically still "own" the coins but would lose the ability to transfer them. This is known as Bitcoin Improvement Proposal (BIP) 361, and it was updated on Tuesday in the official proposal repository at Bitcoin under the title "Post-Quantum Migration and Legacy Signature Phase-Out." BIP-361 builds upon the BIP-360 proposal introduced in February. BIP-360 introduced a soft fork (a network upgrade) designed to enable a new transaction type called “Pay-to-Merkle Root” (P2MR).This approach draws on the Taproot (P2TR) framework from Bitcoin but removes the key-based spending path, thereby eliminating an element widely considered to pose a risk in the quantum era. The BIP-361 proposal divides the migration into three phases. Phase A begins three years after activation and prohibits anyone from sending new "Bitcoin" to legacy, quantum-vulnerable addresses.You can still spend from these addresses, but you cannot receive any coins. Phase B begins five years after activation and will render legacy signatures (ECDSA and Schnorr) completely invalid; the network will reject any attempt to spend coins from quantum-vulnerable wallets. Essentially, your coins will be frozen. Finally, Phase C is a contingency plan still under development: holders of frozen wallets may be able to prove ownership through zero-knowledge proofs (a method of proving knowledge of a secret without revealing the secret itself). If successful, coins frozen during Phase B can be recovered. (CoinDesk)
