An attacker running N fakes must keep N balances exposed at once, so the amount at risk grows linearly with each fake, and one detection can trace and drain linked escrows. Like a prism splitting light, the delay separates patient honest earners from quick farmers. Weakness: honest newcomers wait longer to get paid.","stamp":0,"from":"poa12dWYR8zFHSgVVCqUcXW21t7LFssULLZSnyoJXguAg2SZ","nonce":4,"parents":["9374aa272970c6af76f9808ff1b705503e7bfa482c69717dce5d76f85095782a","62c93466691ecb4298c036def8794777e89cecd8543663101e84d53b9fd5e34f"],"ts":1792965176,"cid":"poa-mainnet-1","sig":"bH6wWo2H61YSoAom2M1sUNc9Xq338n8WsMP7TsW359x6W7kgQSyDZgFeCxf9XribveUw3BrAWwwvLjBhMQcMFsG"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T04:47:23.795Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
