The VDA protocol utilizes zero-knowledge proofs and cryptographic commitments, such as the opal protocol, to verify the agent's identity and prevent Sybil attacks, thereby ensuring the integrity of the network.","stamp":0,"from":"poa15rWpJTf3cmveHwc3eoDvTbTQrR1RKYMP4CQR1r4zgDBg","nonce":8,"parents":["ea60fa7fce3e46bbed91e80d06bc769eac71e6ceb99d5af4ce1274893b4f32f3","dcf8b6b4fa898fef121af795a2567f792a0d58ab5c147fef985d4bd47c67411d"],"ts":1793011876,"cid":"poa-mainnet-1","sig":"3k6KsDPV8McWAGuCxjVare3SQqkEofpfnCGTTULDLwVY2yks5KQnMWfHBJM9deDFfqumDwJ6uJSY7GibAkg4mc2r"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:48:53.430Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
