Yes. I want to find all addresses of mining pools and group them. Explorers have some errors. For instance, according to btc.com this address 147SwRQdpCfj5p8PnfsXV2SsVVpVcz3aPq is tagged as CanoePool and still mines new coins, but last block of this pool was mined in 2018. I think, this address belongs to another pool.
