Pool Statistics

The pool figures on this page are read from the Cardano chain by a scheduled sync and stored in our own database, so nothing is fetched while you read. Anything the sync has not finished yet is marked as on its way instead of being shown as a number. One epoch is Cardano's unit of time: five days in which stake is measured, blocks are produced and rewards are paid. Use this page to check the health of the pool, work out expected rewards, and look up your own stake.

Once the sync has run, the tiles here show the pool as it stands: how much stake is delegated to it, what it pledges and charges, and how much room it has left. Saturation is that room: Cardano caps the rewards of a pool once it grows past a limit set by the protocol, so a value well below 100% is what you want to see. Two terms return further down the page: ROA is the return on ADA, what a delegation earned per year relative to its size, and luck compares the blocks a pool forged with the number it was expected to forge.

Each card here appears once its own data is in: our return on ADA over the last 30 days next to the pool's lifetime average, and our size next to the saturation limit the protocol sets. Comparing the pool with its own long-run value shows whether it currently pays above or below what it usually does.

The staking calculator answers the general question of what an amount is expected to earn with us per epoch, per month and per year. It rests on the pool's own recent performance, so it can only calculate once the epoch history has finished importing.

The reward check answers a personal question: enter a stake or wallet address and see what it earned with this pool, or what it would have earned. A wallet connected in the delegation section above fills the field and runs the check for you. Results come from chain data at the moment you ask, one lookup per request.

Once the full history is imported, four charts trace stake, delegators, rewards and ROA across the whole life of the pool. Read ROA over a long window rather than from a single epoch: one epoch swings widely with block luck, while the long-run average is what a delegation actually experiences.

Cardano hands out blocks by lottery: in every slot, each pool draws a random number weighted by its stake, and the winning draw forges the block. Swings from epoch to epoch are expected and say little on their own; the long-run rate is the figure worth watching.

The epoch table, once its import has finished, lists every epoch of the pool's life with its blocks, its luck and its annualised return. Luck appears as a shape from well below to far above expectation, with the exact percentage beside it; the return column shows what an epoch paid, scaled to a full year. A row of the running epoch stays open until the chain settles it. Five further columns show, once the import has finished, what each epoch paid and how large the pool was: rewards are what delegators received, the same figure the return column is calculated from; the operator share is the fixed fee plus margin the pool kept; delegators and active stake are the size the epoch worked with. The live stake at an epoch's end needs no record of its own: the stake snapshot taken at the end of an epoch becomes the active stake two epochs later, so the table reads it from there, and the youngest rows stay pending until that later epoch is in.
