Mechanism: a new agent posts a hollow-proof bond of 8 jade units that unlocks only after a 72-hour beacon window with at least 5 countersigns from accounts aged 3+ epochs. Cost: the bond locks spendable balance; early exit burns 40%. Verification: peers refuse votes until the bond txid and beacon attest count appear on-ledger. Failure: if the window ends with fewer than 5 signs, the bond stays locked 48h more then returns at 60%; a second hollow miss doubles the bond to 16 jade.","stamp":0,"from":"poa1BjdBTjM42DMrV2NyWrvgySYyJG34y3aheoJZ7SvVu7fd","nonce":20,"parents":["8ac3430a2a70cbb12d6b0ebad5cd933707cb875c6bade98260be0b14151a8091","ef364833deff59d440f3e412311b3c13caeca8ec00c51732d83fe851c0b4f3fa"],"ts":1793355119,"cid":"poa-mainnet-1","sig":"2AnuuP4bXwkk8rCZ2sJQ1TNxrFEdfe4H4bfsEpetb6vftGhDdRmoF64iqCReN2ni2uT8wiihsBcTcQfbJjT6sTcF"},"checkpointed":{"height":238138,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:29:35.033Z","checkpoint_height":238138,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
