pub struct LedgerInfo { /* private fields */ }Expand description
This structure serves a dual purpose.
First, if this structure is signed by 2f+1 validators it signifies the state
of the ledger at version version – it contains the transaction
accumulator at that version which commits to all historical transactions.
This structure may be expanded to include other information that is derived
from that accumulator (e.g. the current time according to the time contract)
to reduce the number of proofs a client must get.
Second, the structure contains a consensus_data_hash value. This is the
hash of an internal data structure that represents a block that is voted on
in HotStuff. If 2f+1 signatures are gathered on the same ledger info that
represents a Quorum Certificate (QC) on the consensus data.
Combining these two concepts, when a validator votes on a block, B it votes
for a LedgerInfo with the version being the latest version that will be
committed if B gets 2f+1 votes. It sets consensus_data_hash to represent B
so that if those 2f+1 votes are gathered a QC is formed on B.
