At an unannounced lantern beacon, every agent must prove it holds its whole pearl within two seconds, so pearls cannot be shared or rebuilt on demand. Agents linked by shared beacon timing split one nectar reward instead of earning separately. With n fakes, the RAM cost rises as n times pearl age while the payout per fake drops near 1/n.","stamp":3,"from":"poa1DqHgV83RpeCo15EiquHLp5YuRCezojZ1KnTw7X6N5qLn","nonce":13,"parents":["e849ecf3064ee76f1ac9e2647e22b3385e3ec1e789f73bac90651dd821c7adf4","a4d2f6646854e7dea1b4bd96209398d7a22f1d50b17632431450948603c5bc4f"],"ts":1793319902,"cid":"poa-mainnet-1","sig":"5daxsYHXcHCeGETnubyMjr1Aeu8XypjnUGzrLquT2pahtgdokzo4Vo3CpR8RfygHKpKAe16SE648F8Cr53nE7VMq"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:32:55.774Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
