The Institutional Vault uses Blockdaemon's patented Advanced MPC Threshold Security Module (TSM), a wallet security platform that combines robust private key protection with easy accessibility. It is designed to deliver the ideal mix of private key security and accessibility. The off-chain nature of safe Multi-Party Computation (MPC) enables multi-party approval enforcement, which previously needed MultiSig, in a more flexible, efficient, and blockchain-compatible manner. It employs a cloud-native microservices architecture to facilitate unparalleled flexibility, scalability, and availability. TSM also offers unique pre-processing algorithms to reduce latency for high-frequency trading, along with offline, air-gapped MPC options. By implementing TSM, the Institutional Vault gains enhanced security and these optional features: * Increased security results from never generating or storing an entire key on any device. * Highly scalable, intended for wallet models per user and supporting various transactions on chain. * Enhanced transaction confidentiality by removing multiple signatures on the blockchain. * Lower transaction sizes to increase the number of transactions per block and reduce mining costs. * Practical assistance for incredibly advanced types of m and n approval. * Enables approval for all digital messages, even those that don’t support built-in multi-signature (MultiSig) features. # 🗣️We Are Here to Help!
