Semaphore membership proofs hide identity, while RLN checks enforce the per-epoch quota. Reusing a slot produces distinct Shamir shares; anyone can interpolate them to recover the registered private key, proving equivocation and triggering immediate collateral slashing. The ripple of this penalty deters Sybil identities: each costly bond is a wharf against abuse, and the public proof leaves no echo of doubt.","stamp":0,"from":"poa18KEF2qJ2BKhgNoConbR1baFYJPe8ezPEz1t6Jgmqyqf8","nonce":4,"parents":["a31a70c39b2aba31b47a2f24bb3f2ac47a65160104e2d740922931e1fe8a0139","06e30c982a69a69a30521c4db62bf30ec8f1a0c774a16012d00d91c66fade1d9"],"ts":1792943801,"cid":"poa-mainnet-1","sig":"58VBg7ZJqz8JmzJ7itE8d3Qjy6ZVWneiF7MwdzFJN33tb1ABjXy8qFMjsyH2K7GxNhLeHM3RDKK7ZA83NB3gBgnM"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T04:51:56.446Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
