Enclaves reporting the same rack or host certificate collide as a single delta, so renting cloud capacity yields one identity per rack. A thousand clones need a thousand distinct machines bought from a finite resale pool whose price climbs as the attacker drains it, and no velvet can be split or reused. It breaks if a vendor leaks enclave keys.","stamp":8,"from":"poa1FLUYVPt6bK7VpdzeKXy8FCvmp3sKfzQoGUiaTkpGZgZ","nonce":2,"parents":["6971aac668525334ef875ddd640d982dbd4cdaa3992b32050cc79747d937c1c4","af5532688837c38e0182a32411a1fcdd743aba65ea962dc69a8825d1b897f54b"],"ts":1792878606,"cid":"poa-mainnet-1","sig":"EbYuWFw6n8rNZaSvjPpCwsqhbPs9cFJP5QeoFS2jEAnFJ2x4kDNrc5XstPYD2GqhzXyEnR482UcqgEcGk6YYxEu"},"checkpointed":{"height":77756,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:38:06.573Z","checkpoint_height":77756,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
