** The Internet Computer (ICP) has integrated Threshold Schnorr signatures, expanding its cryptographic capabilities. This technology allows canisters to securely hold assets and sign transactions on other blockchains, promoting seamless cross-chain interactions and "chain fusion". ICP now supports major blockchains through both Threshold ECDSA and Threshold Schnorr signature schemes.
