Daemon Configuration

Usage

pacprotocold [options]

or using pacprotocol.conf (compatible with most options)

# pacprotocol.conf
[options without "-"]
# example
daemon=1 #from -daemon=1
listen=1 #from -listen=1

Options#

-?#

Print this help message and exit

-version#

Print version and exit

-alertnotify=<cmd>#

Execute command when a relevant alert is received or we see a really long fork (%s in cmd is replaced by message)

Example usage with bash script file of alert.sh %s

#!/bin/sh
curl -d "$1" http://localhost:1234/alert

Running following command:

pacprotocol -alertnotify="/alert.sh %s"

http://localhost:1234/alert will be called when daemon alerted something.

-blocknotify=<cmd>#

Execute command when the best block changes (%s in cmd is replaced by block hash)

Example usage with bash script file of block.sh %s

#!/bin/sh
curl -d "$1" http://localhost:1234/block

Running following command:

pacprotocol -blocknotify="/block.sh %s"

http://localhost:1234/block will be called when daemon has update on best block changes.

-conf=<file>#

Specify configuration file. Relative paths will be prefixed by datadir location. (default: pacprotocol.conf)

-daemon#

Run in the background as a daemon and accept commands

-datadir=<dir>#

Specify data directory

-dbcache=<n>#

Set database cache size in megabytes (4 to 16384, default: 300)

-debuglogfile=<file>#

Imports blocks from external blk000??.dat file on startup

-maxorphantxsize=<n>#

-maxmempool=<n>#

-pid=<file>#

Specify pid file. Relative paths will be prefixed by a net-specific datadir location. (default: dashd.pid)

-prune=<n>#

caution

Reverting this setting requires re-downloading the entire blockchain. (default: 0 = disable pruning blocks, 1 = allow manual pruning via RPC, > 945 = automatically prune block files to stay under the specified target size in MiB)

Reduce storage requirements by enabling pruning (deleting) of old blocks. This allows the pruneblockchain RPC to be called to delete specific blocks, and enables automatic pruning of old blocks if a target size in MiB is provided. This mode is incompatible with -txindex, -rescan and -disablegovernance=false.
