The MPC method
Nowadays the modernization of digital payments through blockchains and cryptocurrencies has proven to be prosperous and hence - in need of better quality security and more enhanced authorization methods. Lately, the MPC model has surpassed Multi-Sig and has become the standard for institutions and businesses who manage cryptocurrencies, transactions and Digital Wallets. MPC stands for “Multi-Party Computation” and includes TSS - Threshold Signature Scheme, which holds multiple approvers and one single key distributed among them for authorization purposes. Transactions are signed, approved and broadcasted with a single signature and the signers’ key shares never become public information, or even leave their holder’s domain.
