There are generally two methods to identify mining pools based on the coinbase
transaction in a block. Firstly, miners often put a human readable (ASCII or
UTF-8) tag in the coinbase transaction. For example, a block mined by the Slush
mining pool might have
/slush/ placed in the coinbase input's script sig.
Miners can be identified by mapping a tag found in the coinbase to the mining
pool identity. Secondly, mining pools often reuse the address where the coinbase
reward is paid to. These can be mapped to the pool identity too.
Both methods produce false negatives if a pool doesn't want to be identified. The coinbase tags are not authenticated. Pools can set a different coinbase tag (e.g. pool A mines his blocks with the coinbase tag of pool B). These would be picked up as false positives. It's however unlikely that a pool would pay the coinbase reward to an address he doesn't control, thus false positives are unlikely.
The mapping of coinbase tags and mining pool addresses is based on data from
0xB10C/known-mining-pools which is a fork from btccom/Blockchain-Known-Pools
which in turn is a fork from blockchain/Blockchain-Known-Pools. These
projects provide a
pools.json file mapping coinbase tags and pool addresses to
The 0xB10C/known-mining-pools repository is included in this repository as
a Git submodule. The
pools.json file is used during the Rust build process to
generate the code mapping coinbase tags and addresses to pool identities. The
code generation can be found in
The 0xB10C/known-mining-pools submodule can be initialized and updated with the following commands.
git submodule init git submodule update
