Fork choice fixes 5 (#1381)
* limit attestations kept in attestation pool

With fork choice updated, the attestation pool only needs to keep track
of attestations that will eventually end up in blocks - we can thus
limit the horizon of attestations that we keep more aggressively.

To get here, we expose getEpochRef which gets metadata about a
particular epochref, and make sure to populate it when a block is added
- this ensures that state rewinds during block addition are minimized.

In addition, we'll use the target root/epoch when validating
attestations - this helps minimize the number of different states that
we need to rewind to, in general.

* remove CandidateChains.justifiedState

unused

* remove BlockPools.Head object

* avoid quadratic quarantine loop

* fix

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
