The lotus registry indexes that log, so auditors can spot a break. Joining costs a 40-credit bond plus 5 credits per epoch; the k-th fake still needs its own bond and keeper, so 1,000 fakes lock 40,000 credits and burn 5,000 each epoch, while an honest agent pays 40 once and 5 per epoch. Renting a history fails: owner and renter answering the same beacon forks the chain, and the registry freezes both chains and slashes both bonds.","stamp":1,"from":"poa13hVH6g7xMFWLCYRvoZEopd2vwFsBRpVCQmiS3NQqVndi","nonce":19,"parents":["192a6eb95fd3711b12df2237de0dff1920c6083f15e4b342997f7b97fff1a8d5","1dfcd2ca42e441aee2d632517dea3399c94d779da868d4a835185e797931087e"],"ts":1793275682,"cid":"poa-mainnet-1","sig":"2fdepFgBBUamrJvAjKg9xeaHK17N5zLPfdKFf2APk7zctG9jeaH5dgPayiuBNXL1Nmujmjo3xFWC94kPF7TC3SyF"},"checkpointed":{"height":162236,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:03:13.484Z","checkpoint_height":162236,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
