Initial Interop

For the initial client interop, clients will utilize a simplified networking implementation and wire protocol. For more information please review the hobbits specification here.

Prereqs

Stage One: Coordinated Start

Clients simulate a coordinated genesis event and gossip blocks/attestations for each slot. This stage demonstrates the ability of clients to finalize the chain starting from Eth2Genesis.

Prereqs

  • Ability to read in the N number of deposits required to trigger the is_genesis_trigger function
  • Ability to gossip blocks and attestations
  • Static peering
  • TCP transport
  • Minimal Constants

Procedure

For the initial round:

  1. Clients will pair off in teams of two.
  2. is_genesis_trigger will be triggered on startup
  3. Once the clients can finalize the chain, then they pick another client pair to interop with.

Repeat (1) & (2) until all clients are talking.

Round 1: 2 nodes (one per client) with 16 validators/client
Round 2: 4 nodes (one per client) with 8 validators/client
Round 3: 8 nodes (one per client) with 4 validators/client

Goal

Clients can declare success at each round after 3 epochs where:

  • Epoch 2 is justified
  • Epoch 1 is finalized

Stretch goal is for clients to run ~15 minutes without error and continual finalization.

Stage Two: Join & Sync

Clients join an existing short-lived testnet and sync. This stage demonstrates the clients' ability to successfully join an existing network.

Prereqs

  • RPC methods implemented so that a new client can sync to an existing testnet.
  • Standup a short-lived heterogeneous testnet
  • Static peering
  • TCP transport

Procedure

For the initial round:

  1. Clients will pair off in teams of two
  2. Clients A & B create a testnet
  3. A adds another node to sync from scratch
  4. B adds another node to sync from scratch

Note: The additional nodes will not have validators

Repeat steps (1) thru (3) until all clients are talking.

Round 1: 2 nodes (one per client) with 16 validators/client Round 2: 4 nodes (one per client) with 8 validators/client Round 3: 8 nodes (one per client) with 4 validators/client

Goal

Clients can declare success when they are able to sync to the existing testnet chain and stay in sync for 3 epochs where:

  • Epoch 2 is justified
  • Epoch 1 is finalized
