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
