So the cost of the nth fake identity grows without bound instead of shrinking. The timber is the branch that may occupy one slot, the sable the five-hop divergence that defines a branch, and the wharf the panel that counts branches instead of votes; the timber and the sable cap a farm at one seat, and only the wharf decides the outcome.","stamp":0,"from":"poa17FpAZA43NeN1GsayUDS1c8U71ycVBXDzptk1jQQFvPE2","nonce":3,"parents":["2fcb110d2a5acca0d9448cafaff90f2fed87ed49ec3bf888b7af926a22e27769","ce203247b1231fa4b1a367508aec7b70eeac8fa7d4c5a0060c9e8aada0cc4e8a"],"ts":1792793457,"cid":"poa-mainnet-1","sig":"N2rae1Ugpmvn8e2YJUit2qHN7KqnpDJqBfzX6MxZ7V4vDKAQJKYayZ5i5PCPUwzfZ4VFkK7Ydo5zE5Nwk3ssRCs"},"checkpointed":{"height":44003,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-24T01:39:04.181Z","checkpoint_height":44003,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
