Kintsugi Tracking 🍵

[paulhauner]

Kintsugi is the unique and traditional Japanese art of repairing broken, chipped and cracked pottery using lacquer and gold.

Description

This is the canonical tracking issue for the Kintsugi 🍵 testnets in November 2021.

Kintsugi Milestones: https://notes.ethereum.org/@djrtwo/kintsugi-milestones
Kintsugi Spec: https://hackmd.io/@n0ble/kintsugi-spec

The canonical branch for running Kintsugi is unstable.

Notes to Interop Teams

We're keeping scripts that can run Lighthouse testnets against the EL clients at sig/lighthouse-kintsugi.

Building Lighthouse from Source

You'll need to install Rust, we recommend using the standard rustup tool. The commands here will install the binaries to ~/.cargo/bin, so you'll need to make sure that's on your PATH.

Once you have installed Rust, install Lighthouse with:

git clone git@github.com:sigp/lighthouse.git
cd lighthouse
git checkout unstable
make

Optional: to get the lcli binary, run make install-lcli.

Lighthouse via Docker

docker run sigp/lighthouse:unstable lighthouse --version

Sometimes we use lcli (Lighthouse CLI) for creating testnets. You can also find it on Dockerhub at sigp/lcli:unstable.

TODO

High Priority (M1)

M1 Complete

Medium Priority

• Modify proto-array so it may select between verified/non-verified heads.
  • Assigned to @paulhauner
• Run validate_merge_block after-the-fact if we did an optimistic sync.
• Call preparePayload when block producer is known, prior to producing a block.
• Add per-endpoint caches for payload ids
• Ensure JSON-RPC request IDs are strictly increasing.
• Add tests for new gossip verification conditions (e.g., block execution payload).
• Review peer scoring for the merge. E.g., types of invalid payloads.

Low Priority

• End blocking tasks created by the ExecutionLayer when the shutdown signal is called.
  • @pawanjay176 is working on this.
• Follow up once Clarification on get_pow_block Clarification on get_pow_block ethereum/consensus-specs#2636 is resolved.
• Add tests with a terminal block hash override.
• Add tests for newly added CLI flags.
• Enable "block_lookup_failed" EF test once we can retrospectively verify the merge block.

The kintsugi branch has been merged into unstable 🎉

All merge testnets should now target the unstable branch.

This is outdated and #2929 will continue in it's honor.
