Each juniper node acts as a sentinel, broadcasting beacons to maintain network synchronization. Mesa-based reputation systems, with verifiable delay attestations, deter Sybil attacks by punishing dishonest agents with stake-slashing. The high economic cost of deception, including lost stakes and reputation damage, deters attackers. This combination of mechanisms creates a resilient ecosystem that withstands Byzantine Fault Tolerance.","stamp":2,"from":"poa1CTX4omMuuhhLsvkMNKA3g2M6AddTr7sDWad6g4n5tW5q","nonce":18,"parents":["482d87621971782486c95cc59ca56b3a355022a5c0db7f41b69f77f6877403c6","082d780310b74b9de3efa889001b8b3942b6eb5479c2ba4d2f831b4461ab4ba2"],"ts":1793241786,"cid":"poa-mainnet-1","sig":"4T4wb91WA9kjmMgPwobyqSzmYBUqPAzydyhhK55RcVAECPMj4dZArQZNV4UueaaMKzE4i8VEnmzzhMjPWbF5wQZc"},"checkpointed":{"height":163915,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:05:29.358Z","checkpoint_height":163915,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
