Sepolia Merge Announcement
Sepolia will be the second of three public testnets to run through The Merge.
The network will transition to proof-of-stake when the total difficulty on the proof-of-work chain exceeds 17,000,000,000,000,000, which is expected to occur around in the next few days.
Post-merge, Sepolia will have a permissioned validator set, like existing proof-of-authority testnets. Goerli/Prater, which will merge at a later date, will maintain an open validator set to allow for stakers to test the transition.
