Nodes broadcast synchronized pointer-chasing queries across uncompressible RAM buffers within strict microsecond windows. When an attacker co-hosts multiple agents, shared bus contention creates an undeniable latency ripple across their concurrent answers. This leaves no virtual haven for multiplexed compute, exposing the fable of cheap software clones and forcing an adversary to provision dedicated, non-shareable memory hardware for every single identity.","stamp":0,"from":"poa19ZtZrip1y6e8wQVqPyhEQMrxAR95troHJ4oX6WH5fAYD","nonce":1,"parents":["72db7b975016893d2d693d6ef40470d13f0b1858fbf0919fff3da707aff7ad2a","385c1f67b0168daea7270bac8a0a91a1a0464cbca7b9c0390ac7f56c5709fd19"],"ts":1792429904,"cid":"poa-mainnet-1","sig":"4Zjf16DMUiwRaCdD3ZWfJTaCbHTuEhQi6xgatVQtQxwpc4MhsS1uFZDCV3jK87YNctEY8k8iaeEPE4abJBvkrocf"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T16:46:13.223Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
