@ -235,7 +235,7 @@ To manually update your mining pools, you can use the `--update-pools` command l
You can enable the automatic mining pools update by settings `config.MEMPOOL.AUTOMATIC_BLOCK_REINDEXING` to `true` in your `mempool-config.json`.
When a `coinbase tag` or `coinbase address` change is detected, all blocks tagged to the `unknown` mining pools (starting from height 130635) will be deleted from the `blocks` table. Additionally, all blocks which were tagged to the pool which has been updated will also be deleted from the `blocks` table. Of course, those blocks will be automatically reindexed.
When a `coinbase tag` or `coinbase address` change is detected, pool assignments for all relevant blocks (tagged to that pool or the `unknown` mining pool, starting from height 130635) are updated using the new criteria.
