Bitcoin core developer releases storage prototype on secure chain

Bitcoin core developer Bryan Bishop has released a secure on-chain storage prototype. Bishop launched a prototype of "Bitcoin Vault" without a fork on GitHub and shared it on the Bitcoin Core email list. The basic idea of ​​this prototype involves storing Bitcoin on the chain in a particularly secure way so that it can recover from security errors. The on-chain method is part of the reason why Bishop's vaults are different from cold wallets.
