Introduction

ncli is a set of low level / debugging tools to interact with the nimbus beacon chain specification implementation, simliar 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 nim-beacon-chain

git clone https://github.com/status-im/nim-beacon-chain.git
cd nim-beacon-chain
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
