source · [−]
Expand description

defines block cost related limits

Structs

BUILT_IN_INSTRUCTION_COSTS
Number of compute units for each built-in programs

Constants

COMPUTE_UNIT_TO_US_RATIO
Cluster averaged compute unit to micro-sec conversion rate
DATA_BYTES_UNITS
Number of data bytes per compute units
MAX_ACCOUNT_DATA_BLOCK_LEN
max length of account data in a block (bytes)
MAX_BLOCK_REPLAY_TIME_US
Static configurations:
MAX_BLOCK_UNITS
Statically computed data:
MAX_CONCURRENCY
number of concurrent processes,
MAX_VOTE_UNITS
Number of compute units that a block can have for vote transactions, sets at ~75% of MAX_BLOCK_UNITS to leave room for non-vote transactions
MAX_WRITABLE_ACCOUNT_UNITS
Number of compute units that a writable account in a block is allowed. The limit is to prevent too many transactions write to same account, therefore reduce block’s parallelism.
SIGNATURE_COST
Number of compute units for one signature verification.
WRITE_LOCK_UNITS
Number of compute units for one write lock
