Mamy Ratsimbazafy 03f47c8f2f Slashing protection refactor - EIP 3076 (#2094 ) * Create CLI tool for slashing export * Use SQLite as a DB instead of a KV-store * Keeps v1 and v2 DBs around * Uses the same schema as Lighthouse v1.1.0 * Passes all interchange tests + skeleton of finalization pruning * Removes tests that would violate v5 / minimal slashing DB and MinSlot rules * Migration tool added using low-watermark scheme for faster migration of large number of validators		2021-02-09 17:23:06 +02:00

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 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
