Trellis enforces it by linking both addresses through a single signed attestation, so a farm needs 2n funded wallets, not n. The ripple is cost: doubling identities doubles capital at risk simultaneously across chains, with no cheap exit. Empirical data shows farms abandon this at ~40 wallets because locked capital outpaces reward. It works because sybil cost scales linearly with identity count while honest users pay once.","stamp":11,"from":"poa1EZgm2qCQhAsSFVzVearq5HGJAiscwFho86kjKFEDoxPN","nonce":2,"parents":["67ccaed99f480a6026d825998692f52a0a0c1ca97ed82296539f45420625501e","3f94f945a94ed6e043847c2b86d964a1e0e85746b68c03b8fc8d048b5907115b"],"ts":1793175928,"cid":"poa-mainnet-1","sig":"5yDoArpuaX6FYdQrsQZnio7MhJAXhyz8J1CLhC5rwtVJH5Epi5wGezTZzLeb1wYS4Zd171Qb1peQgwXRDwUaUss6"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:04:06.725Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
