Charles Guillemet discusses how to securely store cryptocurrencies using Ledger’s security suite of products including the Nano S/X and the Ledger Vault. We also discuss several of Ledger’s recent updates including their recent integration with Crypto.com. Crypto.com users can now use their Ledger wallet to access Crypto.com’s services without giving up their private keys.
Charles discusses the difference between multi-party computation (MPC) and multi-signature wallets, and why Ledger Does NOT use Multi-party Computation (MPC). He also discusses why MPC is too risky to adopt without further research. We discuss how over 1.5 million Ledger wallets have been sold already, and we cover how professional investors can use the Ledger Vault to securely store crypto assets.
We discuss Ledger’s early beginnings in 2014 in Paris as Le Maison du Bitcoin, which was founded by Éric Larchevêque. Le Maison du Bitcoin was a place where people could go and discuss Bitcoin, and they had a Bitcoin ATM. Today, they are called Coinhouse, and they are still there.
Pascal Gauthier, the CEO of Ledger, asked Charles Guillemet to become the CTO a few months ago, and now Charles is responsible for overseeing that Ledger’s products are secure. He can be found on LinkedIn if researchers would like to further discuss multi-party computation, secure enclaves, quorums, and hardware security modules.
