Struct ckb_jsonrpc_types::BlockTemplate [−][src]
A block template for miners.
Miners optional pick transactions and then assemble the final block.
Fields
version: Version
Block version.
Miners must use it unchanged in the assembled block.
compact_target: Uint32
The compacted difficulty target for the new block.
Miners must use it unchanged in the assembled block.
current_time: Timestamp
The timestamp for the new block.
CKB node guarantees that this timestamp is larger than the median of the previous 37 blocks.
Miners can increase it to the current time. It is not recommended to decrease it, since it may violate the median block timestamp consensus rule.
number: BlockNumber
The block number for the new block.
Miners must use it unchanged in the assembled block.
epoch: EpochNumberWithFraction
The epoch progress information for the new block.
Miners must use it unchanged in the assembled block.
parent_hash: H256
The parent block hash of the new block.
Miners must use it unchanged in the assembled block.
cycles_limit: Cycle
The cycles limit.
Miners must keep the total cycles below this limit, otherwise, the CKB node will reject the block submission.
It is guaranteed that the block does not exceed the limit if miners do not add new transactions to the block.
bytes_limit: Uint64
The block serialized size limit.
Miners must keep the block size below this limit, otherwise, the CKB node will reject the block submission.
It is guaranteed that the block does not exceed the limit if miners do not add new transaction commitments.
uncles_count_limit: Uint64
The uncle count limit.
Miners must keep the uncles count below this limit, otherwise, the CKB node will reject the block submission.
uncles: Vec<UncleTemplate>
Provided valid uncle blocks candidates for the new block.
Miners must include the uncles marked as required
in the assembled new block.
transactions: Vec<TransactionTemplate>
Provided valid transactions which can be committed in the new block.
Miners must include the transactions marked as required
in the assembled new block.
proposals: Vec<ProposalShortId>
Provided proposal ids list of transactions for the new block.
cellbase: CellbaseTemplate
Provided cellbase transaction template.
Miners must use it as the cellbase transaction without changes in the assembled block.
work_id: Uint64
Work ID. The miner must submit the new assembled and resolved block using the same work ID.
dao: Byte32
Reference DAO field.
This field is only valid when miners use all and only use the provided transactions in the template. Two fields must be updated when miners want to select transactions:
S_i
, bytes 16 to 23U_i
, bytes 24 to 31
See RFC Deposit and Withdraw in Nervos DAO.
