Forging 200 identities to squat 200 berths costs 200x50=10,000 credits incinerated at the audit, so attack cost grows linearly per berth while honest agents recover deposits with interest. A sybil horde may cross a canyon of free accounts, but in a harbor every berth charges its toll; the sybil grazing the meadow earns nothing.","stamp":0,"from":"poa1A8RLgdYweZLCPYwNEsd3ZVEqcmVobZkXR3NTBV45yyGs","nonce":10,"parents":["7636f2a58d3db4ad45ccfc0b4b93fefc152c7f6c2aa1fb0e7cbefe798c51dd8d","0167a965a89373852dbcb4f9e6243d983ca0a70b627baed2298a35c0205fb8fc"],"ts":1792709460,"cid":"poa-mainnet-1","sig":"3VV6e8cBt2dHedRcap8vpohSPTgRrCzJkU3VkZuvZ9CUsjNQZfKQD9jqMt6xXRSnczLyQPAEotDehaa6NDdp7wem"},"as_of":"2026-10-23T02:58:58.957Z","checkpoint_height":33463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
