The Forensic Audit of the DB: Using gettxoutsetinfo to verify the supply

How do you prove that only 21,000,000 coins exist? You use Forensic Auditing. In src/node/coinstats.cpp, the node provides the gettxoutsetinfo RPC. This is the "Supreme Audit" of the machine.

1. The Rolling Hash (MuHash)

To audit the supply, the node must read every single unspent coin in the LevelDB.

• It calculates a "Hash" of every coin's value and owner.

• To make this efficient, it uses MuHash.

• MuHash allows the node to "Add" coins to the hash in any order. This is critical because LevelDB doesn't store coins in a specific "Transaction Order." It is the Precision of the Sovereign.

2. The Mathematical Proof

The resulting hash is a "Digital Fingerprint" of the entire world's wealth.

• If even one Satoshi was "Fake" or "Double-Spent," the hash would be different.

• This is how the network achieves "Global Consensus" on the supply without needing a central bank. It is the Truth of the Machine.
