* speed up state/block loading When loading blocks and states from db/era, we currently redundantly check their CRC32 - for a state, this costs 50ms of loading time presently (110mb uncompressed size) on a decent laptop. * remove `maxDecompressedDbRecordSize` - not actually used on recent data since we store the framed format - also, we're in luck: we blew past the limit quite some time ago * fix obsolete exception-based error checking * avoid `zeroMem` when reading from era store see https://github.com/status-im/nim-snappy/pull/22 for benchmarks * bump snappy
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
