# Towards a multi-client ethereum 2.0 testnet

_Field notes of Afri trying to see where the top ETH 2.0 clients are regarding interop._

- Previous research: https://hackmd.io/Nx204wkTSgeGB0UzNXhz9g
- Thoughts on chain specs: https://github.com/ethereum/eth2.0-specs/issues/1662

#### Step 0 - the deposit contract "ceremony"

- Reference: https://ethereum.stackexchange.com/questions/80258
- Will use Görli testnet for deposit contract: https://github.com/goerli/testnet
- Will use a new contract instance to not interfere with existing testnets
- Ref: https://github.com/ethereum/eth2.0-specs/blob/dev/specs/phase0/deposit-contract.md
- Contract: https://github.com/ethereum/eth2.0-specs/blob/dev/deposit_contract/contracts/validator_registration.vy
- https://github.com/ethereum/eth2.0-pm/blob/master/interop/deposit_contract_testnets/README.md

#### Step 1 - the transition specification

- Giving this testnet a working title `schlesi`
- Using a modified `mainnet.yaml` https://github.com/ethereum/eth2.0-specs/blob/dev/configs/mainnet.yaml
- `DEPOSIT_CONTRACT_ADDRESS: 0xaA888248144Bc5d584a7f400839d0D912F21C39A`
- `GENESIS_FORK_VERSION: 0x00000539`
- `BLS_WITHDRAWAL_PREFIX: 0x05`
- `MIN_GENESIS_ACTIVE_VALIDATOR_COUNT: 16`
- `MIN_GENESIS_TIME: 1584316800` (Mar/16, 2020)
- `MIN_DEPOSIT_AMOUNT: 100000000` (0.1 GöETH)
- `MAX_EFFECTIVE_BALANCE: 3200000000` (3.2 GöETH)
- `EJECTION_BALANCE: 1600000000` (1.6 GöETH)
- `EFFECTIVE_BALANCE_INCREMENT: 100000000` (0.1 GöETH)
- `ETH1_FOLLOW_DISTANCE: 16`
- `MIN_GENESIS_DELAY: 3600`
- Full config: https://gist.github.com/q9f/d6eea3ea3356e41bde81864143284ce9
- See also for unknown constants: https://github.com/ethereum/eth2.0-specs/issues/1662

#### Step 2 - bootstrapping the network with three clients

- Reference: https://ethereum.stackexchange.com/questions/80264
- "ETH2 Testnets" https://github.com/eth2-clients/eth2-testnets
- **Lighthouse**
- Supports reading YML configs
- Requires additional files for deposit contract, deposit block, genesis state, boot records
- `lcli` allows for configuring testnets
- Resources: https://notes.ethereum.org/--DbdqzWTMOABRmcGq0Hkg

### Personal Eth2.0 Call 36 Notes

I want to talk about mult-client testnets
- how we can assist client teams to work towards one testnet for all clients.
- I don't know if/how this fits in the agenda, but this call would be the ultimate chance to touch base with all developer teams and afterwards, we can spin out dedicated testnet calls (if the timing is appropriate).

I'm mainly interested in
- which version of the spec is implemented in which client;
- what's the status of networking in each client; what's the status validating/syncing;
- what else do we need to address first;
- and who's ready in the next weeks to join the efforts creating a persistent multi-client testnet? spider_web
