Bitcoin Covenants: MATT and OP_CHECKCONTRACTVERIFY enable stateful contracts
The mechanism known as OPCHECKCONTRACTVERIFY (OPCCV) allows contract state to be directly integrated into Taproot output keys, thereby enforcing legitimate state changes right on the blockchain.
The mechanism known as OP_CHECKCONTRACTVERIFY (OP_CCV) allows contract state to be directly integrated into Taproot output keys, thereby enforcing legitimate state changes right on the blockchain. This innovative capability unlocks the potential for creating stateful contracts while simultaneously enabling more compact fraud proofs.
