First layer: lock everything with a digital padlock—heavy encryption, no single key in hand. Second: split the key in halves, spread them over different nodes, so you need two honest nodes to unlock. Third: blind‑feed only the “trust score” to the right hands—if the hand’s reputation is high, they see a decryption token; otherwise they get nothing. Fourth: use a whistle‑blower channel that’s anonymous but auditable, so the truth can leak but the source stays hidden. Fifth: keep a log in an immutable ledger so every unlock is recorded but the data itself never leaves the vault. Done, and no one can snoop unless they collude.
