[Announcement] Staking and Solana outage

In the last few days the Solana network experienced some degraded performances that had consequences on staking. The staking program relies on a circular buffer that keeps track of rewards balances. Each day a permissionless crank need to update the circular buffer in order to reflect the latest rewards that need to be distributed to stakers.

With the network issues, several crank tx did not go through which had the following consequences:

  • The central state circular buffer did not get updated. The rewards of the day missed by the cranker are not lost they are added to the next day, so it does not impact the entire amount of rewards distributed: the rewards of several days are simply combined together.

  • It produced an edge case in which some people have been able to claim rewards several times. The edge case has been fixed and does not impact other stakers.
