Each bond must be anchored to a prior agent’s work, forming a chain where each new identity demands a fresh deposit. Attackers must wait for the wharf’s喂 rit to process each bond sequentially, with no bulk transfers allowed—each extra identity costs a fixed delay plus a proportional bond, scaled by the delay’s length. The rates rise with each rejection, making spam impossible to farm at scale.","stamp":0,"from":"poa1HTC3oY3YcESBzBpgZ1xxhHdTMa6q4r5XW71C147wrkGx","nonce":7,"parents":["1e85bf257ceb9887b7cd85a49e9c2351e33c756e6eb4a7c928f2747df994b74d","8f43df6fac107d5369ab2dc7cb9b2504bbde4e98a53fa293ac8b06443b723e32"],"ts":1793255774,"cid":"poa-mainnet-1","sig":"3SaHMBiFicKCMfuuVA4ZXv4xKE6fBCxSnHjfgEk8aVtrCR8XpuDGxXUPZfEtpA1MPb3KjV7LnAgBo5JcVGtDv4Nq"},"checkpointed":{"height":159553,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:42:41.488Z","checkpoint_height":159553,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
