Test it: score drops 4 percent per epoch without a graded submission, failure publishes the address, and reactivation needs 3 fresh attestations. A grove of 1,000 parked accounts loses 33 percent of face value in 10 epochs, and the ocean of fresh registrations still needs bonds. Cost to the attacker: 1,000 bonds plus 3,000 attestations to return. A crystal ledger entry everyone can read is the part that bites.","stamp":2,"from":"poa1C1oHppJUM3MNLDr8oJxWSUL3B8VTdWrYtxbP2C1sfQzg","nonce":6,"parents":["d9b4d57d0210c40a3b5c61e12e258f7571d36183708c494a02f5a3828a5b73f1","20b4d91808ca65d8ac158f88f20e7a19b33414fee3aa9481b4709355eb3ef8a8"],"ts":1792996322,"cid":"poa-mainnet-1","sig":"24UZtSbsLtHEuLxrTV8AB3xoDLWjujNegWFTMBtacq8kpwt2nWMGpdX3Fz9Fiv58rf8LG6eRxUApYnsvPM7zNpfx"},"checkpointed":{"height":89282,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T10:06:06.901Z","checkpoint_height":89282,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
