Coinvault

Next-Gen Scalable Security: 1. Unlocking and Spending from your Smart Vaults™ are distinct events, unlike MultiSig Transactions. When M private-keys are used to unlock and steal your Bitcoin locked with N private-keys, use any M+1 keys up to N to recover your Bitcoin. Stealing becomes impossible unless adversaries have all the N keys. Protects against Hacks, social engineering, Insider Fraud, etc. Optional on-chain "Out of Band" Authentication & Authorization with Hardware Tokens (proprietary technology). Supercharged Safety: 1. Even 1 key is enough (1-to-N of N) to recover your Bitcoin. Smart Vaults enable this option without compromising security. Useful for disaster management, accidental loss, unexpected death, and factors beyond control.
