Fix the `/eth/v1/beacon/deposit_snapshot` API to produce proper EIP-4881 compatible `DepositTreeSnapshot` responses. The endpoint used to expose a Nimbus-specific database internal format. Also fix trusted node sync to consume properly formatted EIP-4881 data with `--with-deposit-snapshot`, and `--finalized-deposit-tree-snapshot` beacon node launch option to use the EIP-4881 data. Further ensure that `ncli_testnet` produces EIP-4881 formatted data for interoperability.
Introduction
ncli
is a set of low level / debugging tools to interact with the nimbus beacon chain specification implementation, similar to zcli. With it, you explore SSZ, make state transitions and compute hash tree roots.
Tools
- transition: Perform state transition given a pre-state and a block to apply (both in SSZ format)
- hash_tree_root: Print tree root of an SSZ object
- pretty: Pretty-print SSZ object as JSON
Building
Follow the instructions from nimbus-eth2
git clone https://github.com/status-im/nimbus-eth2.git
cd nimbus-eth2
make
Usage
# Build with minimal config
../env.sh nim c -d:const_preset=minimal ncli_transition
# Build with mainnet config
../env.sh nim c -d:const_preset=mainnet ncli_transition
# Run..
./ncli_transition --help
