OP_CAT will be launched on the Bitcoin Signet testnet next Tuesday. OP_CAT (ie BIP-420) is planned to be launched on the Bitcoin Signet testnet at block height 193,536 (expected next Tuesday). Signet is a Bitcoin test network designed for developers to test software. There are no miners, no proof of work, and an average of one block is created every 10 minutes. According to previous news, the Bitcoin Improvement Proposal BIP-420 has officially introduced the restoration of the OP_CAT opcode, which is designed to enable Bitcoin contracts (covenants) and support the development of smart contracts, security bridges, and on-chain transactions. The BIP-420 proposal, written by Ethan Heilman and Armin Sabouri, aims to reintroduce OP_CAT into Bitcoin via a backwards-compatible soft fork by "redefining the opcode OP_SUCCESS126." twitter.com/udiWertheimer/status/1784200418551087151
