"NEAR did unprecedented work on chain signatures" "unprecedented" is doing a lot of work here, threshold ECDSA, one key, sign on any chain, no bridge, shipped on internet-computer:native protocol-native, subnet-level DKG, asynchronous & byzantine-robust, with formal security proofs. NEAR's chain signatures shipped in 2024 and it's not even onchain, but an 8-node, appointed, permissioned side MPC network. So the "unprecedented engineering" is really "we shipped what ICP shipped protocol native, as offchain MPC." @NEARProtocol even cites @dfinity math for their offchain MPC bolt-on.😉 Don't believe me? Check the official $NEAR docs: docs.near.org/chain-abstract… In the "Derivation Paths: One Account, Multiple Chains" section, click the Additive Key Derivation link. It takes you to a @dfinity paper (click the PDF icon on the site). The funny part is, put the signer contract on any another blockchain (ETH, SOL, SUI... any smart-contract one), attach the MPC bolt-on, and it'll be "unprecedented engineering" for that chain too, without needing $NEAR at all. btw @LitProtocol already runs the same type, offchain, permissioned MPC, live on Ethereum today. 😉
