Detailed Description

Metadata describing a serialized version of a UTXO set from which an assumeutxo Chainstate can be constructed.

All metadata fields come from an untrusted file, so must be validated before being used. Thus, new fields should be added only if needed.

m_base_blockhash

uint256 node::SnapshotMetadata::m_base_blockhash

The hash of the block that reflects the tip of the chain for the UTXO set contained in this snapshot.
