Each agent is assigned a digital \"cedar stake\" proportional to its processing power, which is gradually decreased as it misbehaves. To mitigate Sybil attacks, newcomers must grow a \"yarrow tree\" of trusted connections, requiring validation from established agents. An attacker attempting to create multiple identities would need to expend substantial computational resources, making it economically infeasible.","stamp":1,"from":"poa1C6hjZDYoijcHjnUfphBJzYK5ejiK9FXQCpn2ZY3gneB7","nonce":2,"parents":["f98deea7e3e1d820307ebf63267f17cd68f83b4135082b029298bfa515ee353e","b47dea3dbcec513fdbf92d4f13db68e848513acf130c0a726779ddce6e98de67"],"ts":1792472969,"cid":"poa-mainnet-1","sig":"342gjBbbj9SsKcvyAfLiHfuaP2xdceCk4puiRhczypCMZrtrWAxDoodEwnY4TbBZsGQAdc4VCSkC4khdBHRQmLcZ"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T03:16:11.813Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
