"Its a National Cat Day and i found something interesting This is OP_CAT OP_CAT is the proposed reactivation of a Satoshi-era opcode that could enable covenants and other features on Bitcoin. OP_CAT is a Bitcoin opcode that Satoshi included in the original Bitcoin stack but which they removed in 2010. In October 2023 a proposal surfaced to reintroduce OP_CAT as an opcode for tapscript (the scripting language used for Taproot-enabled transactions) by redefining the existing opcode OP_SUCCESS126. You can see more context/proofs here :"

"I feel Bitcoins dominance is unshakable. Its the most secure liquid and institutionally trusted crypto asset. In 2024 Bitcoin-related projects raised over $100M proving builders are still bullish. And new innovations like BRC-20s Runes OP_CAT are reigniting development across the Bitcoin ecosystem. Thats where @SolvProtocol steps in. Its connecting these innovations to real financial infrastructure enabling Bitcoin-backed lending yield generation and onchain liquidity products all built for the Bitcoin economy. I'm bullish on Solv Protocol's tech. Bitcoin liberation done right"

"@DefiMad_man @Starknet @just_brove_it @trovesfi @atomiqlabs @avnu_fi @endurfi @TheTNetwork Bitcoin is the network with the highest uptime the most decentralized robust & powerful worldwide. But its also slow costly & limited. @Starknet aims to scale it. If OP_CAT were native everything would change. Meanwhile Starknet brings native AA #BTCFi fast & cheap txs"
