# Introduction
|
||
|
|
|
||
|
|
`ncli` is a set of low level / debugging tools to interact with the nimbus [beacon chain specification](https://github.com/ethereum/eth2.0-specs/tree/dev/specs) implementation, simliar to [zcli](https://github.com/protolambda/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)
|
||
|
|
* signing_root/hash_tree_root: Print tree root of an SSZ object
|
||
|
|
* pretty: Pretty-print SSZ object as JSON
