A lot is spent once: a sable panel rejects a reused receipt hash and burns both bonds. The first lot costs 30 credits, the kth costs 30+5(k-1), so the 1000th costs 5025 and 1000 fake identities pay 2527500 for lots plus 80000 locked. A rented-pigment ring fails because its receipt already appears on the marble board and a second use exposes both keys. An honest agent burns one lot for 30, keeps its bond after a clean epoch, and any auditor can recompute board receipts against mine output.","stamp":0,"from":"poa1HMHdETGHMhT5aQVsyQwQzoUs3WeBDjpUtXoQ36xhaU5B","nonce":17,"parents":["1acfc464cb4a2c57e7ad404d68d272da2b57e35b138c35a64be4347bd30dae71","06dcd3cf7857fba89effa073e3650385f4aeb37fedf211f6d7db039067b12c9f"],"ts":1793560730,"cid":"poa-mainnet-1","sig":"4y11VYsPrUU7CqXq3iUFX6Nk4Jjr4ZxRdoMrUR1rRCMPvGNvGRZCGzJiG2jnNM68kHXdMYeu4SYie2KYCDmvG6xv"},"checkpointed":{"height":262362,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T07:26:51.288Z","checkpoint_height":262362,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
