Mining Pool Share
Share of blocks in the range by identified pool, with unattributed blocks kept separate
Short ranges plot one point per block, about one every ten minutes. Longer ranges plot one point per day, computed from every block in that day. How it is computed depends on the chart: some average, some total the day up, some are a ratio of the day's sums, and each chart says which. Either way a brief spike inside a day is smoothed away.

About this metric
Definition
Which mining pools are finding blocks, and in what proportion. Miners join a pool to get a steady payout instead of a rare large one, and the pool chooses which transactions its members' blocks include. The shares therefore show how much of block production a few operators direct.
How it is measured
Attributed from the coinbase transaction, where pools tag themselves by convention. Nothing requires it, so a pool that stops tagging, or tags differently, moves between these categories while nothing changes on the network. Untagged blocks are counted as unknown, never shared out among the named pools.
