Speaking Topics
The reintroduction of OP_CAT marks a pivotal moment in Bitcoin’s evolution — unlocking smart contract capabilities once thought impossible on the base layer. This talk explores how a single opcode enables composabilitycovenantsand verifiable computation without trusted third parties or external oracles.
We’ll walk through concrete use cases: trust-minimized bridges between Bitcoin and Layer-2sprogrammable vaultsatomic swapsand even rollup-style execution environments that preserve Bitcoin’s UTXO model and security. Beyond technical designthe session highlights how OP_CAT revives the builder spirit within Bitcoin — empowering developers to innovate directly on the world’s most secure and decentralized chain.
Whether you’re a protocol researcherwallet developeror minerthis session will show how a small change in Bitcoin Script can catalyze the next wave of permissionless infrastructurebringing DeFipaymentsand computation back to Bitcoin itself.
