According to Odaily, StarkWare has implemented its new STARK verifier on the Bitcoin test environment, Signet network, utilizing the OP_CAT technology. OP_CAT is a proposed upgrade for Bitcoin aimed at introducing Ethereum-style 'smart contract' programmability. While OP_CAT has garnered support, it is still in the early stages of gaining the consensus needed for integration into Bitcoin's core software. The company stated in a press release, 'StarkWare publicly supports the approval of this proposal as it will bring significant benefits to the Bitcoin community and the broader blockchain ecosystem.'
