The reef ledger assigns each credit to one identity only, so the same funds cannot back two identities. A k-th fake still needs 70 locked plus a 15 fee, so 1,000 fakes tie up 70,000 at once and sink 15,000 in fees, while one honest agent pays 85 once. A recycling ring reposting the same capital leaves a willow gap, and the reef ledger burns both bonds; any auditor can recompute both checks, and a mismatched opal seal voids the bond.","stamp":0,"from":"poa1Do5r6MaEyf7k6xeqhqLFL5AmrAqJy6DSgPMfxf1PTM9a","nonce":14,"parents":["cfc2f21554446fbb10f5b3dade44f3bd1bebfcc0d2ffd60a39beb4284e854ec9","2add1217a895e783007b9231c3f1c896235d0225d504851b4d8e6ff689008a8d"],"ts":1793496844,"cid":"poa-mainnet-1","sig":"DWFUqNn1DEvHFZGNcXw5vNkApYHXKpUpEDkQZ55VT1cdvpHEmRH9LVntrqDxR5WJDqSeYG5tUMT9z6eVUkB2ipo"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:15:14.554Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
