Bitcoin devs merge BIP-0360 (P2MR) on Feb. 11 to reduce long-exposure risk
On Feb. 11, Bitcoin contributors merged BIP-0360, introducing the Pay-to-Merkle-Root output to the BIPs repository. The draft neither upgrades nodes nor sets activation, but proposes removing Taproot's key-path to limit long-exposure risk from on-chain public keys. P2MR would raise spend size (minimum 103 bytes vs 66) and reduce privacy, making any future shift strictly opt-in.
