Firstly, the custodians need to use encryption technology to securely protect currency transactions and ensure that data cannot be tampered with. Secondly, they reach consensus on the issuance and trading of new currency through consensus algorithms, such as the SHA-256 algorithm and the proof of  work (PoW) mechanism used by Bitcoin. Based on this, the custodians can set specific module permissions, such as limiting currency issuance or trading permissions for specific addresses, achieving precise control over minting. Meanwhile, the custodians of the blockchain also need to..."}]}],"pr":"2e95e8c44d16d101ba4704da4e13bbe2c3d753d7f233384645f951039e7072a6"}
