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.
i can't find the tag but you can easily decode the scriptsig of the coinbase transaction like this:
03f5870941d7a2ae3df2c5b341d7a2ae3d6dd57c2f315448617368263538434f494e2ffabe6d6d403ace9685148ea02d7933281963b2c04b0f9c99b2b6c6accf23638a6e0d7b4980000000000000009606ba787843c40000000000
first 4 bytes are the block height:
03-f58709
the rest is usually a push of the name of the pool but can contain other stuff:
hex = 41d7a2ae3df2c5b341d7a2ae3d6dd57c2f315448617368263538434f494e2ffabe6d6d403ace9685148ea02d7933281963b2c04b0f9c99b2b6c6accf23638a6e0d7b4980000000000000009606ba787843c40000000000
UTF8 = Aע�=�ųAע�=m�|/1THash&58COIN/��mm@:Z���-y3(c��K����Ƭ�#c�n

pool name is: /1THash&58COIN/
