+By default, mining pools will be not automatically updated regularly (`config.MEMPOOL.AUTOMATIC_BLOCK_REINDEXING` is set to `false`). 

 To manually update your mining pools, you can use the `--update-pools` command line flag when you run the nodejs backend. For example `npm run start --update-pools`. This will trigger the mining pools update and automatically re-index appropriate blocks.
