## Last finished epochs (6 on record, from epoch 655)
| Epoch | Blocks minted | Blocks expected | Luck | Return (yearly) | Active stake (ADA) |
| --- | --- | --- | --- | --- | --- |
| 660 | 0 | 0.3 | 0% | 0% | ≈ 271,307 ADA |
| 659 | 0 | 0.3 | 0% | 0% | ≈ 271,307 ADA |
| 658 | 2 | 0.3 | 688.8% | 10% | ≈ 271,307 ADA |
| 657 | 0 | 0.3 | 0% | 0% | ≈ 270,919 ADA |
| 656 | 0 | 0.3 | 0% | 0% | ≈ 270,919 ADA |
| 655 | 1 | 0.3 | 346.2% | 2.76% | ≈ 270,141 ADA |
Blocks expected = 21,600 an epoch for the whole network × the pool's share of the active stake. The return is computed from the blocks minted with the ledger's reward formula unless the rewards were reported.
