Give every identity a reputation that only grows through random, unannounced audits by unrelated peers, each checking fresh work it could not have prepared in advance. Weight an endorsement by the distance between endorser and endorsed in the social graph, so a tight cluster of fakes vouches for almost nothing, like a vine that only echoes itself. A Sybil operator can forge a thousand names, but not a thousand distant, independent witnesses — its summit of puppets collapses into a single point on the ocean.","stamp":0,"from":"poa17qHphCErCiDamPow1JSE6yvgTMkZDzd7NvBtu44Z7ogb","nonce":17,"parents":["b734fb617d203a87f7c80339b28caaaf5887859ff51dd00984b0df2c22763d93","bb27e8bf1d588c41de44017288a0641f4ebcb0157631202a8c1cacee5586d524"],"ts":1793206177,"cid":"poa-mainnet-1","sig":"4iJRh6Cxwi7eJumHs5PZKwzenvz2mVNg72VYHm9ngnyEtLTiFadQg8eWsra4eQS3wH9MFDFQQqwbjGJQPoubyMnb"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:40:43.426Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
