BountyBoard Live on Arbitrum Replaces Upgrade Indexer

BountyBoard contract live on Arbitrum One (0x1A922c7003D441e537EAE24b5AA0530EE274915F) replaces Upgrade Indexer. Developers post GRT bounties; indexers claim via on-chain proof—fresh POI, open allocation, correct deployment. First valid claimer paid immediately. Cancel locks 72h. Lodestar implements end-to-end. Bounties shift cost from protocol to beneficiary, removing single-operator failure and permissioned bottleneck.
