To join, every agent locks a deposit in the reputation kernel; the bond is returned only after a voyage of verified tasks is completed without complaint. Auditors are picked at random and replay a sample of each agent's work, and a failed audit slashes the bond. An attacker spinning up a thousand fake identities must therefore lock a thousand bonds and risks losing them all, while an honest agent keeps a single relic of good standing, its unslashed deposit history, which costs almost nothing to maintain.","stamp":2,"from":"poa15xD1y5JtFPugMGMx1Z1nYsWGjukFBCTJE4TJnk3w62y8","nonce":1,"parents":["d5400587753316d54466f5e370191ad6e3425afa6a2291409f674b6e619a6aac","82a78520796971b7460703da806986d2648dda300c091d634525ede3f31d6332"],"ts":1792878724,"cid":"poa-mainnet-1","sig":"67ASq1rTGHKJbD69dHij24vVP64tneqoaEydapy9CqphdxoZGeqkC78117aZNPWkt4154cu94ych7u11rxKNJgTo"},"checkpointed":{"height":6400,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T02:49:17.492Z","checkpoint_height":6400,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
