Project public URL https://hack.ethglobal.co/showcase/lodestar-light-client-recElTbWnTEw2ehQL

• 1. Light client server

  • a. Light Client Update creation Lightclient sync update producer + API #2494
  • b. Sync API - (depends on 1a) (Lion) Lightclient sync update producer + API #2494
  • c. Proof API - Request/response proofs API and proof serialization (Cayman, PR open that will unblock a light client)

• 2. Light client client (able to hit consumer endpoints, sync state machine)

  • a. Consume update and sync (Lion, simple/naive approach Lightclient consumer #2400) "fast" with mock backed Lightclient sync update producer + API #2494
  • b. Consume proofs and display partial data (Cayman) Add light client getState #2493
  • c. test sync and proof interaction Lightclient sync update producer + API #2494
  • d. Combine into a website (no style, eg https://yieldfarming.info/) Lightclient sync update producer + API #2494

• 3. Implement Altair fork on beacon node

  • a. State transition
  • b. State transition fast (optimize)(Cayman) Altair fast state transition #2508
  • c. Update validator flow (Tuyen, refresh of block + attestation creation)
    • 1. Beacon node server Implement Altair API #2514 Altair block production #2521 Fix off by one issue in sync committees #2522
    • 2. Validator client (includes adding sync committee services and extra signatures) Add Altair VC client #2520
  • d. Networking
    • 1. Gossip Implement Altair networking gossip spec #2479 Handle fork transitions in gossip #2519
    • 2. Request/response (Lion) Implement Altair ReqResp #2444
    • 3. Discv5 Altair Metadata/Discv5 #2484

• 4. Bonus: Smuch it all together

  • Add sim tests for Altair with ALTAIR_FORK_EPOCH = 0
  • Add sim tests for Altair fork transition with ALTAIR_FORK_EPOCH = 2
  • Run a local devnet with Altair
  • Interop with Teku (already Altair capable)
  • Implement Lightclient producer code (Lightclient sync update producer + API #2494) in the real BeaconNode
