What is Multi-Signature (Multisig)? 🗝️🗝️ Imagine a physical vault that requires two different keys held by two different people to open. That is exactly what Multisig does for your Bitcoin. In a standard wallet, if you lose your key (or it gets stolen), your sats are gone. In a Multisig setup (like a 2-of-3), you can lose one key and still recover your funds with the other two. This is how Federated Mints work. Instead of one person controlling the Bitcoin backing the eCash, a group of "Guardians" must agree to move the funds. This is the gold standard for businesses and families. It moves us away from "trusting a person" to "trusting a distributed process". The Lesson: Security isn't just about a "strong password"—it's about distribution. By using Multisig, you become your own bank with built-in redundancy.
