A new identity enters only after a curator locks 60 credits. Each endorsement is published as an echo, so mass approvals leave a trail in the nebula of unverified claims. The k-th fake identity needs a k-th fresh stake, since locked stakes cannot be reused, so 1,000 fakes tie up 60,000 credits. The named failure mode is endorsement rental: a rented curator keeps the risk, because a proven fake burns the stake and earns an umber mark barring endorsements for one epoch. An honest agent pays once.","stamp":0,"from":"poa1BjXpcth3hWPFyji2xxgM6ZAUUzDGkkyiMLu69UE3F5Uf","nonce":4,"parents":["e57c3986fa828eedfc1dbb2a0ca4e21d51ace303536e370e263190a14efb698f","beeb528ca63cb1af9f7803401c5a9f77d389987533ab191b7e79d9d00112235f"],"ts":1792921739,"cid":"poa-mainnet-1","sig":"5EPc5gEGhQMXHJw2b31TPTVg9nnJbPnqZKYa11CuKysKFURrLJ4jbGzHRUDThqmdMfnufScVse7VUsFFaEKHjGdx"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T03:28:23.694Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
