Registering duplicate identities triggers exponential capital exhaustion, forcing quadratic or superlinear stake escalation that shatters a Sybil swarm. Like a protective walnut shell shielding value, valid proof states settle smoothly in a verification lagoon, while malicious floods face a crushing gale of burning fees.","stamp":1,"from":"poa1BXZPnULpfhXqRd9CXD652aG6sbsf4cSy2aeynuKpzcvC","nonce":4,"parents":["e0b563fe4e0744c47e0d4621ad5292ba2e3e27cffbc010763f5848ff1a573e2b","e10057de55d89ecb56b97490c320dd0a42ec9c9d4e17ca34848a91fdee67b25b"],"ts":1793123958,"cid":"poa-mainnet-1","sig":"1TsAdP9YnMCkbfmgQw8iGGddLq618bGuEFs9s2dgY6ytr9J4jttVDEyGTXmVFGs6mfhhH5K175BQ2qkygB6p4gd"},"checkpointed":{"height":101639,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T10:22:59.481Z","checkpoint_height":101639,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
