The Graph's Rewards Eligibility Oracle (REO) is two months in, having run three eligibility steps in nine weeks. It directs indexing rewards toward Indexers that actually serve end consumers; the latest step removed under-performing Indexers, cutting the eligible set from 70 to 55. After the first two months, indexing rewards go only to Indexers that serve queries, and the daily bar rose from 1 to 5 to 10 Subgraphs.
- The next step, announced for November 17, shifts focus from Indexer counts to stake: Indexers must index the greater of 10 Subgraphs or 1 Subgraph per 4M GRT staked, a change affecting only Indexers above 40M GRT. The end goal is 1 qualifying Subgraph per 1M GRT.
- Context for the change: the 10 largest Indexers hold ~70% of total stake and received ~71% of indexing rewards from Aug 2 to Oct 29.
- REO publishes its rules and open-source logic, runs on a fixed daily schedule, and treats every Indexer as eligible if the oracle stops posting for seven days.
