-datacarrier

-maxstackmemoryusageconsensus

Set maximum stack memory usage in bytes used for script verification we're willing to accept from any source (0 = unlimited) after Genesis is activated (consensus level). This is a required parameter. The value may be given in bytes or with unit (B, kB, MB, GB).

-maxstackmemoryusagepolicy

Set maximum stack memory usage used for script verification we're willing to relay/mine in a single transaction (default: 100 MB, 0 = unlimited) after Genesis is activated (policy level). The value may be given in bytes or with unit (B, kB, MB, GB). Must be less or equal to -maxstackmemoryusageconsensus.

-maxstdtxvalidationduration=<n>

-maxtxchainvalidationbudget=<n>

Set the upper limit of unused validation time to add to the next transaction validated in the chain (min 0ms, default: 50ms)

Maximal number of inputs of a non-first-layer transaction that can be scheduled for re-validation. (default:5) TxnValidator options:

-numstdtxvalidationthreads=<n>

Set the number of 'High' priority threads used to validate standard txns (dynamically calculated default: 6)

-numnonstdtxvalidationthreads=<n>

Set the number of 'Low' priority threads used to validate non-standard txns (dynamically calculated default: 2)

-maxstdtxnsperthreadratio=<n>

Set the max ratio for a number of standard txns per 'High' priority thread (default: 1000)

-maxnonstdtxnsperthreadratio=<n>

Set the max ratio for a number of non-standard txns per 'Low' priority thread (default: 1000)

-txnvalidationasynchrunfreq=<n>

Set run frequency in asynchronous mode (default: 10ms)

-txnvalidationschedulestrategy=<strategy>

Set task scheduling strategy to use in parallel transaction validation.Available strategies: CHAIN_DETECTOR (legacy), TOPO_SORT (default)

-maxtxnvalidatorasynctasksrunduration=<n>

Set the maximum validation duration for async tasks in a single run (default: 10000ms)

-maxcoinsviewcachesize=<n>

Set the maximum cumulative size of accepted transaction inputs inside coins cache (default: unlimited -> 0). The value may be given in bytes or with unit (B, kB, MB, GB).

-maxcoinsprovidercachesize=<n>

Set soft maximum limit of cached coin tip buffer size (default: 1 GB, minimum: 1 MB). The value may be given in bytes or with unit (B,kB, MB, GB).

-maxcoinsdbfiles=<n>

Set maximum number of files used by coins leveldb (default: 64).

-txnvalidationqueuesmaxmemory=<n>

-maxgenesisgracefulperiod=<n>

Set maximum allowed number of blocks for Genesis graceful period (default: 72) where nodes will not be banned for violating Genesis rules in case the calling node is not yet on Genesis height and vice versa. Seting 0 will disable Genesis graceful period. Genesis graceful period range :(GENESIS_ACTIVATION_HEIGHT  - n |...| GENESIS_ACTIVATION_HEIGHT |...| GENESIS_ACTIVATION_HEIGHT + n) Invalid transactions sink options:

-invalidtxsink=<sink>

Set destination for dumping invalid transactions. Specify separately for every sink you want to include. Available sinks:FILE, ZMQ, (no sink by default)

-invalidtxfilemaxdiskusage=<n>
