Henri Vultiding Rank Quantum Jump Success/Series 2 Analyzing the Security Structure of TSS·MPC Based Wallets Two hours ago, it was said that it entered the 7D top 80!! It has quantum jumped to the mid-40s!! We will continue the series so that you can use it as material for your discussions!! Start! The security of cryptocurrency goes beyond just making strong passwords; the real key is "where and how to store the private key." 1. Risks of Private Keys: Centralized Single Point of Failure In the structure of existing wallets, "one private key" manages everything. If a hacker steals this one key, they can take all the assets. Most of the problems that arise here are due to people. Incorrect backups, phishing links, cloud synchronization, etc. All stem from user negligence. Ultimately, the philosophy of Vultisig @vultisig is that we must prevent human error with technology. (In fact, this is not a new approach. In industrial settings, during process improvement projects, what is called Human Validation is considered very important to prevent failures caused by people.) 2. TSS (Threshold Signature Scheme)/Decentralization of Signature Shares TSS divides a single signature into multiple shares and distributes them across different devices. These shares are just random numbers without any meaning until they are completed. (It reminds me of scenes in movies where necklaces are split and shared, later used as tokens ^^) Only when executing a transaction do the shares communicate with each other to temporarily create a single signature. And once that process is complete, the shares return to their independent states. In other words, it is a technology that makes the private key itself non-existent. 3. MPC (Multi-Party Computation)/Secure Computation Without Trust MPC allows different devices to perform joint calculations without trust. For example, when three devices A, B, and C are signing, each one does not reveal their share but only shares the computation results to complete the final signature. This structure does not require a central server or trusted institution. (If it's a blockchain project, that's obvious ^^) In other words, even if the Vultisig server is hacked, it cannot access the user's personal assets. 4. Combination of Two Technologies/Vultisig's Differentiation Vultisig combines TSS and MPC to provide fast execution speed without signature delays even in combinations of multiple devices and multiple signers. This means an environment optimized for institutions, DAOs, funds, and multi-signature teams. In a way, Vultisig is differentiated not by being "strong in security" but by "simultaneously achieving security and usability."
