Method Detail

getVersion

long getVersion()

 Current latest version of the system
 

uint64 version = 1;

getTransactionAccumulatorHash

com.google.protobuf.ByteString getTransactionAccumulatorHash()

 Root hash of transaction accumulator at this version
 

bytes transaction_accumulator_hash = 2;

getConsensusDataHash

com.google.protobuf.ByteString getConsensusDataHash()

 Hash of consensus-specific data that is opaque to all parts of the system
 other than consensus.  This is needed to verify signatures because
 consensus signing includes this hash
 

bytes consensus_data_hash = 3;

getConsensusBlockId

com.google.protobuf.ByteString getConsensusBlockId()

 The block id of the last committed block corresponding to this ledger info.
 This field is not particularly interesting to the clients, but can be used
 by the validators for synchronization.
 

bytes consensus_block_id = 4;

getEpochNum

long getEpochNum()

 Epoch number corresponds to the set of validators that are active for this
 ledger info. The main motivation for keeping the epoch number in the
 LedgerInfo is to ensure that the client has enough information to verify
 that the signatures for this info are coming from the validators that
 indeed form a quorum. Without epoch number a potential attack could reuse
 the signatures from the validators in one epoch in order to sign the wrong
 info belonging to another epoch, in which these validators do not form a
 quorum. The very first epoch number is 0.
 

uint64 epoch_num = 5;

getTimestampUsecs

long getTimestampUsecs()

 Timestamp that represents the microseconds since the epoch (unix time) that is
 generated by the proposer of the block.  This is strictly increasing with every block.
 If a client reads a timestamp > the one they specified for transaction expiration time,
 they can be certain that their transaction will never be included in a block in the future
 (assuming that their transaction has not yet been included)
 

uint64 timestamp_usecs = 6;
