set upper bound on EpochRef cache (#2403) 
* set upper bound on EpochRef cache

* max 32 EpochRef instances
* less memory waste in BlockRef by removing EpochRef seq that is mostly
unused (~20mb)
* less memory waste in dag block lookup by not keeping an extra copy of
digest (~70mb)
* fix `==` and `$` for Eth2Digest
* remove `ChainDAG.tmpState` (~50mb?)

all in all, this branch cuts mainnet memory usage by ~160-180mb and puts
limits on EpochRef cache usage - where normally it hovered around 950mb
before, it's now sitting at 600-700mb on my machine.

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
