EIP-4881 was never correctly implemented, the `DepositTreeSnapshot` structure has nothing to do with its actual definition. Reflect that by renaming the type to a Nimbus-specific `DepositContractSnapshot`, so that an actual EIP-4881 implementation can use the correct names. - https://eips.ethereum.org/EIPS/eip-4881#specification Notably, `DepositTreeSnapshot` contains a compressed sequence in `finalized`, only containing the minimally required intermediate roots. That also explains the incorrect REST response reported in #5508. The non-canonical representation was introduced in #4303 and is also persisted in the database. We'll have to maintain it for a while.
Introduction
ncli is a set of low level / debugging tools to interact with the nimbus beacon chain specification implementation, similar 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
