What is Multi-Party Computation (MPC)?

This article introduces Multi-Party Computation (MPC) and its application to crypto wallets, explaining how secrets can be split and shared (SSSS, VSS) and how Threshold Signature Schemes (TSS) enable distributed key generation and signing without a single dealer. It compares MPC wallets to multisig, lists advantages (key refresh, flexibility, chain-agnosticity, recovery, lower fees, role/limit management) and outlines security considerations and attack vectors (phishing, single-point-of-failure in some schemes, DoS risks, Forget-and-Forgive attacks) and trade-offs between security and performance.
