e2store: avoid uint48 (#4625)
In SSZ, `uint32` is used for offsets, effectively limiting the size of
an SSZ entry to 2**32 bytes.

Also, `uint48` isn't a valid SSZ type, so the header was not correctly
defined according to the SSZ spec - the extra 2 bytes are left for
future expansion instead.

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
