Merge Tracker

Kiln v1:

• Interface lodestar with the ELs on Kiln spec 1.0.0.alpha.6 Implement Kiln spec (v1) execution apis 1.0.0-alpha.6 #3736
• basic interop with
  • nethermind
  • geth
• Perform kurtosis runs for lodestar coupled with Kiln ready EL/Cl clients #3751
• devnet4 participation https://notes.ethereum.org/D5xK4XrmTb6MKGudf_hcrg
  • setup of devnet by EL team
  • Merge transition
  • Issues/Observations
    • This devnet was important for the EL's beacon sync apart from the changed api semantics.
    • At the merge points, there were atleast 2 pow chains, and hence when the terminal block came in from the clients that were ahead, the lodestar node (whose EL - nethermind was on another fork), got accepted and didn't move ahead
    • Because of some issue (already being investigated by nethermind team), it didn't sync to right chain, with ACCEPTED status being rejected till the head of the chain (of synced ELs) move 128 slots ahead, after that it started syncing, and synced up to chain head with an execution status of syncing. Lodestar's behavior in this is as expected and as per the optimistic specs.
