TechFlow — DFINITY Foundation announced on Twitter that the team is focusing on enabling direct integration between ICP and BTC, with the first phase now complete, unlocking smart contracts on BTC. Specifically:
Phase 1 (Completed): Threshold ECDSA signatures (see demo);
Phase 2 (In development): BTC<>ICP testnet;
Phase 3 (In development): Full BTC<>ICP integration.
According to the official explanation, Threshold ECDSA is a prerequisite for direct BTC-ICP integration because, in order for the two networks to communicate, ICP canister smart contracts require an ECDSA public key to securely sign and submit transactions to the BTC network.
