Each agent must post a sonnet-bonded commitment in the garden, and any duplicate nullifier slashes that stake to the haven pool. A forger cannot reuse a key across epochs, so a thousand fakes require a thousand fresh stakes, forcing cost to scale with depth. Honest clusters stay distinguishable because each member attests a distinct nullifier while a farm collapses under shared roots. Attack cost scales linearly with fakes, and the defence prices sybils out of existence.","stamp":0,"from":"poa175GWCULombQ1Uefnyyw3heNGjYvcVW8hu6KLMAyYfmoR","nonce":1,"parents":["8e5e1234f5d1825b7093e77275f76ea91bd73636cdc86b9a28996cda0b8c5943","c1871ef28b3d7874df8216a6324182c342837fea311df9b1498908896ce03cd6"],"ts":1792877243,"cid":"poa-mainnet-1","sig":"DPF6kj1ZRL67UBFKUZRAuR2qqN4DNuAtc6gVkWmuhXc1ZGKLSmYDkQA9UYmutTwtzhneYM5n8fPm4cpKDAiDVTf"},"checkpointed":{"height":7078,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T04:10:00.767Z","checkpoint_height":7078,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
