# How to run Hive with Lodestar Get repo and build it (requires Go lang) ``` git clone https://github.com/ethereum/hive go build . ``` Checkout branch depending on current progress. For capella Mario's working on `eth2-withdrawals-interop`. Check with Mario Vega on current branch if working on new forks. `master` should reflect configurations that are somewhat stable. To run a test do: ``` ./hive --client go-ethereum,lodestar-bn,lodestar-vc --sim eth2/withdrawals --sim.limit "/test-capella-fork" --sim.loglevel 5 ``` - `client`: flag sets which combo to run. For the example above, if you don't provide EL, CL and VC the test breaks: `client go-ethereum,lodestar-bn,lodestar-vc`. To test an interaction between Lodestar and Teku, do: `client go-ethereum,lodestar-bn,lodestar-vc,teku-bn,teku-vc`. - `--sim eth2/withdrawals`: runs the entire suit of tests under `eth2/withdrawals` - `--sim.limit "/test-capella-fork"` regex on specific test name. Find the full list of tests `names of tests: ./hive/simulators/eth2/withdrawals/main.go` - `--sim.loglevel 5` to enable debug logging. Logs can be found at `workspace/logs`, for example `workspace/logs/lodestar-vc/client-9740bcdf5ddfc43dd3f14c40bb7b616e559dde0edd33bc2099f8a3c829879811.log`

Increase `CHURN_LIMIT_QUOTIENT`

Rationale Current CHURN_LIMIT_QUOTIENT in Gnosis is low such that the network's validator set can change significantly in short periods of time posing unnecessary risks to the network. The original value was chosen without a great deal of care to facilitate staker onboarding UX. Even that argument will no longer apply with eip6110 (in-protocol deposits). CHURN_LIMIT_QUOTIENT dictates the validator_churn_limit which is constant through an epoch variable only to active validator count. def get_validator_churn_limit(state: BeaconState) -> uint64: """ Return the validator churn limit for the current epoch. """ active_validator_indices = get_active_validator_indices(state, get_current_epoch(state))

GC withdrawal contract

Background From Spec Gnosis Chain withdrawals #1 During block processing, state transition must call WITHDRAWAL_CONTRACT function function withdrawals(uint64[] amounts, address[] addresses) If transaction reverts, the block is invalid. So if a specific state (i.e. not enough funds) causes a revert in all cases, the network halts Deposit flow Bridge GNO from mainnet to Gnosis Chain

Blobs booby-trap :bomb:

Given the conditions: To ensure an upper-bounded disk size, consensus clients must only store blobs within the MIN_EPOCHS_FOR_BLOBS_SIDECARS_REQUESTS time range Blobs from finalized blocks are considered available If the latest finalized checkpoint is before MIN_EPOCHS_FOR_BLOBS_SIDECARS_REQUESTS, there exist a range of blocks which cannot be checked for is_data_available. More context on ethereum/consensus-specs/pull/3141 Range sync When performing a range sync the client cannot know the latest finalized checkpoint until it syncs to the head. There are two possible scenarios:
