Methodology
The 6 blocks from the tip of the blockchain (including the most recent block) are assessed. Coin Metric employs a proprietary entity clustering methodology in order to identify major mining pools & miners. The coinbase output field used by miners to self-identify is also used to help assess miner identities.
Available Assets (v1)

* Historical data covering the pre-merge timeframe only (up to 9/15/2022). With the merge ETH switched from Proof of Work and miners to Proof of Stake and validators meaning the network no longer has any miners as of the merge date.
