For blocks, this means verifying state transition and all contained cryptographic signatures (instead of just the proposer signature).

Important distinction:
- We distinguish attestation `validation` which is defined in the P2P specs:

- single: https://github.com/ethereum/consensus-specs/blob/v1.0.1/specs/phase0/p2p-interface.md#beacon_attestation_subnet_id
- aggregated: https://github.com/ethereum/consensus-specs/blob/v1.0.1/specs/phase0/p2p-interface.md#beacon_aggregate_and_proof
A validated attestation or aggregate can be forwarded on gossipsub.
- and we distinguish `verification` which is defined in consensus specs:
https://github.com/ethereum/eth2.0-specs/blob/v1.0.1/specs/phase0/beacon-chain.md#attestations
https://github.com/ethereum/consensus-specs/blob/v1.0.1/specs/phase0/beacon-chain.md#attestations
An attestation needs to be verified to enter fork choice, or be included in a block.
To be clarified: from the specs it seems like gossip attestation validation is a superset of consensus attestation verification.

# 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.
