Block template creation options. These override node defaults, but can't exceed node limits (e.g. block_reserved_weight can't exceed max block weight).
Declared in <node/mining_types.h>
struct BlockCreateOptions;
| Name | Description |
|---|---|
block_max_weight | Maximum block weight, defaults to -maxblockweight |
block_min_fee_rate | Minimum fee rate for transactions to be included. Providing a value overrides the -blockmintxfee startup setting. |
block_reserved_weight | The default reserved weight for the fixed-size block header, transaction count and coinbase transaction. Minimum: 2000 weight units (MINIMUM_BLOCK_RESERVED_WEIGHT). |
coinbase_output_max_additional_sigops | The maximum additional sigops which the pool will add in coinbase transaction outputs. |
coinbase_output_script | Script to put in the coinbase transaction. The default is an anyone-can-spend dummy. |
print_modified_fee | Whether to log the fee rate of each transaction when it is added to the block template. Providing a value overrides the -printpriority startup setting. |
test_block_validity | Whether to call TestBlockValidity() at the end of CreateNewBlock(). Should only be disabled for tests / benchmarks. |
use_mempool | Set false to omit mempool transactions |
| Name | Description |
|---|---|
CheckMiningOptions | Check option values for validity. Returns an error for invalid values. |
FlattenMiningOptions | Replace null optional values with their hardcoded defaults. |
MergeMiningOptions | Merge two BlockCreateOptions structs, replacing null values in x with non-null values from y. |
ReadMiningArgs | Read the mining options set in args. Returns an error if one was encountered. |
