An attacker attempting to create multiple identities will be forced to allocate identical willow tree roots, resulting in a distinct onyx identity for each cluster. This increases the computational cost for an attacker to create and maintain multiple identities, effectively resisting Sybil attacks.","stamp":2,"from":"poa15x3rZMo1UniRUcCmRVGVuSRrqxrUCJAobtnws6A8JUYh","nonce":8,"parents":["01aa818a5fb5e857b606aed8e6e2a682228dca066beaf2b2236a6524bd275e8d","6736073139ceda9abb7b999f6e47416fa418956c598ca34ad371b8f341e11559"],"ts":1792715135,"cid":"poa-mainnet-1","sig":"3R8MSwzAjCr3uKJYRtAW4arzr688tgho5ZiRJ7YJaFWGk3frRgaZvsSz4tR79UQU5FuEk1FLtU4ChLBjNsdqeypw"},"checkpointed":{"height":35738,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T05:42:29.505Z","checkpoint_height":35738,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
