An update on the slashing incident: as of May 20, 2023 (specifically Epoch 202374 or 202375, depending on the validator), the 11 validators in question are now withdrawable (and have thus stopped accumulating penalties). The remaining balance for these validators be withdrawn when the withdrawals sweep cycles around to those indices, which should be within the next 1-2 days.
The breakdown of the total penalties and missed rewards can be found in the below-attached image. Actual total penalties have been calculated as the change in balance of the relevant validators as of the slashing epoch for each validator up until the epoch that each became withdrawable. Missed rewards have been calculated in the same manner that they were in the post mortem. Note that there was an unexpected network event that caused a brief period of inactivity leak, which introduced a minor amount of penalties which could not have been calculated earlier. However, the actual amount of penalties was still less than the initially projected amount per the post mortem.
For those who wish to check or re-perform the calculations there are two options:
- Using the public Ethereum beacon chain dataset on BigQuery (user must pay for queries)
- Using the beaconcha.in API (only yields penalties)
Note that penalties for specific duties (attestations, proposals, etc.) are based on calculation and cannot be queried directly from chain data.
As voted upon by the DAO earlier, the amount will be covered via the slashing cover fund. This will occur via the burning stETH shares representing 13.45978634 stETH thereby increasing the value of other stETH tokens. An on-chain Aragon vote will follow in which the funds will be transferred to the burn contract, to be burned with the following on-chain accounting oracle report.
