Properties

Optional bonus

bonus?: number

the potential bonus payout for this block.

Optional congestionTax

congestionTax?: number

the fee required, beyond the minimum fee, for "normal" transactions in this block.

Optional feesCollected

feesCollected?: number

the sum of all fees paid by transactions in this block.

genesisHash

genesisHash: Uint8Array

(gh) hash to which this block belongs.

genesisId

genesisId: string

(gen) ID to which this block belongs.

Optional load

load?: number

the degree to which this block is full, based on the number of bytes in the final block compared to the maximum allowed. Expressed as a fixed-point integer with 6 digits of precision, so 1,000,000 is a completely full block.

Optional participationUpdates

participationUpdates?: indexerModels.ParticipationUpdates

Participation account data that needs to be checked/acted on by the network.

previousBlockHash

previousBlockHash: Uint8Array

(prev) Previous block hash.

Optional previousBlockHash512

previousBlockHash512?: Uint8Array

(prev512) Previous block hash, using SHA-512.

Optional proposer

proposer?: Address

the proposer of this block.

Optional proposerPayout

proposerPayout?: number

the actual amount transferred to the proposer from the fee sink.

Optional rewards

rewards?: BlockRewards

Fields relating to rewards,

round

round: bigint

(rnd) Current round on which this block was appended to the chain.

seed

seed: Uint8Array

(seed) Sortition seed.

Optional stateProofTracking

stateProofTracking?: StateProofTracking[]

Tracks the status of state proofs.

timestamp

timestamp: number

(ts) Block creation timestamp in seconds since eposh

Optional transactions

transactions?: indexerModels.Transaction[]

(txns) list of transactions corresponding to a given round.

transactionsRoot

transactionsRoot: Uint8Array

(txn) TransactionsRoot authenticates the set of transactions appearing in the block. More specifically, it's the root of a merkle tree whose leaves are the block's Txids, in lexicographic order. For the empty block, it's 0. Note that the TxnRoot does not authenticate the signatures on the transactions, only the transactions themselves. Two blocks with the same transactions but in a different order and with different signatures will have the same TxnRoot.

transactionsRootSha256

transactionsRootSha256: Uint8Array

(txn256) TransactionsRootSHA256 is an auxiliary TransactionRoot, built using a vector commitment instead of a merkle tree, and SHA256 hash function instead of the default SHA512_256. This commitment can be used on environments where only the SHA256 function exists.

Optional transactionsRootSha512

transactionsRootSha512?: Uint8Array

(txn512) TransactionsRootSHA512 is an auxiliary TransactionRoot, built using a vector commitment instead of a merkle tree, and SHA512 hash function instead of the default SHA512_256.

Optional txnCounter

txnCounter?: number

(tc) TxnCounter counts the number of transactions committed in the ledger, from the time at which support for this feature was introduced. Specifically, TxnCounter is the number of the next transaction that will be committed after this block. It is 0 when no transactions have ever been committed (since TxnCounter started being supported).

Optional upgradeState

upgradeState?: BlockUpgradeState

Fields relating to a protocol upgrade.

Optional upgradeVote

upgradeVote?: BlockUpgradeVote

Fields relating to voting for a protocol upgrade.
