.HP
\fB\-blockfilterindex=\fR<type>
.IP
Maintain an index of compact filters by block (default: 0, values:
basic). If <type> is not supplied or if <type> = 1, indexes for
all known types are enabled.
.HP

.IP
Extra transactions to keep in memory for compact block reconstructions
(default: 100)
.HP
\fB\-blocksdir=\fR<dir>
.IP
Specify directory to hold blocks subdirectory for *.dat files (default:
<datadir>)
.HP
\fB\-blocksonly\fR
.IP
Whether to reject transactions from network peers. Automatic broadcast
and rebroadcast of any transactions from inbound peers is
disabled, unless the peer has the 'forcerelay' permission. RPC
transactions are not affected. (default: 0)
.HP
\fB\-coinstatsindex\fR
.IP
Maintain coinstats index used by the gettxoutsetinfo RPC (default: 0)
.HP
\fB\-conf=\fR<file>
.IP
Specify path to read\-only configuration file. Relative paths will be
prefixed by datadir location (only useable from command line, not
configuration file) (default: bitcoin.conf)
.HP
\fB\-daemon\fR
.IP
Run in the background as a daemon and accept commands (default: 0)
.HP
\fB\-daemonwait\fR
.IP
Wait for initialization to be finished before exiting. This implies
\fB\-daemon\fR (default: 0)
.HP
\fB\-datadir=\fR<dir>
.IP
Specify data directory
.HP
\fB\-dbcache=\fR<n>
.IP
Maximum database cache size <n> MiB (4 to 16384, default: 450). In
addition, unused mempool memory is shared for this cache (see
\fB\-maxmempool\fR).
.HP
\fB\-debuglogfile=\fR<file>
.IP
Specify location of debug log file. Relative paths will be prefixed by a
net\-specific datadir location. (\fB\-nodebuglogfile\fR to disable;
default: debug.log)
.HP
\fB\-includeconf=\fR<file>
.IP

.HP
\fB\-maxorphantx=\fR<n>
.IP
Keep at most <n> unconnectable transactions in memory (default: 100)
.HP
\fB\-mempoolexpiry=\fR<n>
.IP
Do not keep transactions in the mempool longer than <n> hours (default:
336)
.HP
\fB\-par=\fR<n>
.IP
Set the number of script verification threads (\fB\-10\fR to 15, 0 = auto, <0 =
leave that many cores free, default: 0)
.HP
\fB\-persistmempool\fR
.IP
Whether to save the mempool on shutdown and load on restart (default: 1)
.HP
\fB\-pid=\fR<file>
.IP
Specify pid file. Relative paths will be prefixed by a net\-specific
datadir location. (default: bitcoind.pid)
.HP
\fB\-prune=\fR<n>
.IP
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 \fB\-txindex\fR. Warning: Reverting this setting
requires re\-downloading the entire blockchain. (default: 0 =
disable pruning blocks, 1 = allow manual pruning via RPC, >=550 =
automatically prune block files to stay under the specified
target size in MiB)
.HP
\fB\-reindex\fR
.IP
Rebuild chain state and block index from the blk*.dat files on disk.
This will also rebuild active optional indexes.
.HP
\fB\-reindex\-chainstate\fR
.IP
Rebuild chain state from the currently indexed blocks. When in pruning
mode or if blocks on disk might be corrupted, use full \fB\-reindex\fR
instead. Deactivate all optional indexes before running this.
.HP
\fB\-sandbox=\fR<mode>
.IP
Use the experimental syscall sandbox in the specified mode
(\fB\-sandbox\fR=\fI\,log\-and\-abort\/\fR or \fB\-sandbox\fR=\fI\,abort\/\fR). Allow only expected
syscalls to be used by bitcoind. Note that this is an
experimental new feature that may cause bitcoind to exit or crash
unexpectedly: use with caution. In the "log\-and\-abort" mode the
invocation of an unexpected syscall results in a debug handler
being invoked which will log the incident and terminate the
program (without executing the unexpected syscall). In the
"abort" mode the invocation of an unexpected syscall results in
the entire process being killed immediately by the kernel without
executing the unexpected syscall.
.HP
\fB\-settings=\fR<file>
.IP
Specify path to dynamic settings data file. Can be disabled with
\fB\-nosettings\fR. File is written at runtime and not meant to be
edited by users (use bitcoin.conf instead for custom settings).
Relative paths will be prefixed by datadir location. (default:
settings.json)
.HP
\fB\-startupnotify=\fR<cmd>
.IP
Execute command on startup.
.HP
\fB\-sysperms\fR
.IP
Create new files with system default permissions, instead of umask 077
(only effective with disabled wallet functionality)
.HP
\fB\-txindex\fR
.IP
Maintain a full transaction index, used by the getrawtransaction rpc
call (default: 0)
.HP
\fB\-version\fR
.IP
Print version and exit
.PP
Connection options:
.HP
\fB\-addnode=\fR<ip>
.IP
Add a node to connect to and attempt to keep the connection open (see
the addnode RPC help for more info). This option can be specified
multiple times to add multiple nodes; connections are limited to
8 at a time and are counted separately from the \fB\-maxconnections\fR
limit.
.HP
\fB\-asmap=\fR<file>
.IP
Specify asn mapping used for bucketing of the peers (default:
ip_asn.map). Relative paths will be prefixed by the net\-specific
datadir location.
.HP
\fB\-bantime=\fR<n>
.IP
Default duration (in seconds) of manually configured bans (default:
86400)
.HP
\fB\-bind=\fR<addr>[:<port>][=onion]
.IP
Bind to given address and always listen on it (default: 0.0.0.0). Use
[host]:port notation for IPv6. Append =onion to tag any incoming
connections to that address and port as incoming Tor connections
(default: 127.0.0.1:8334=onion, testnet: 127.0.0.1:18334=onion,
signet: 127.0.0.1:38334=onion, regtest: 127.0.0.1:18445=onion)
.HP
\fB\-cjdnsreachable\fR
.IP
If set, then this host is configured for CJDNS (connecting to fc00::/8
addresses would lead us to the CJDNS network, see doc/cjdns.md)
(default: 0)
.HP
\fB\-connect=\fR<ip>
.IP
Connect only to the specified node; \fB\-noconnect\fR disables automatic
connections (the rules for this peer are the same as for
\fB\-addnode\fR). This option can be specified multiple times to connect
to multiple nodes.
.HP
\fB\-discover\fR
.IP
Discover own IP addresses (default: 1 when listening and no \fB\-externalip\fR
or \fB\-proxy\fR)
.HP
\fB\-dns\fR
.IP
Allow DNS lookups for \fB\-addnode\fR, \fB\-seednode\fR and \fB\-connect\fR (default: 1)
.HP
\fB\-dnsseed\fR
.IP
Query for peer addresses via DNS lookup, if low on addresses (default: 1
unless \fB\-connect\fR used)
.HP
\fB\-externalip=\fR<ip>
.IP
Specify your own public address
.HP
\fB\-fixedseeds\fR
.IP
Allow fixed seeds if DNS seeds don't provide peers (default: 1)
.HP
\fB\-forcednsseed\fR
.IP
Always query for peer addresses via DNS lookup (default: 0)
.HP
\fB\-i2pacceptincoming\fR
.IP
If set and \fB\-i2psam\fR is also set then incoming I2P connections are
accepted via the SAM proxy. If this is not set but \fB\-i2psam\fR is set
then only outgoing connections will be made to the I2P network.
Ignored if \fB\-i2psam\fR is not set. Listening for incoming I2P
connections is done through the SAM proxy, not by binding to a
local address and port (default: 1)
.HP
\fB\-i2psam=\fR<ip:port>
.IP
I2P SAM proxy to reach I2P peers and accept I2P connections (default:
none)
.HP
\fB\-listen\fR
.IP
Accept connections from outside (default: 1 if no \fB\-proxy\fR or \fB\-connect\fR)

\fB\-listenonion\fR
.IP
Automatically create Tor onion service (default: 1)
.HP
\fB\-maxconnections=\fR<n>
.IP
Maintain at most <n> connections to peers (default: 125). This limit
does not apply to connections manually added via \fB\-addnode\fR or the
addnode RPC, which have a separate limit of 8.
.HP
\fB\-maxreceivebuffer=\fR<n>
.IP
Maximum per\-connection receive buffer, <n>*1000 bytes (default: 5000)
.HP
\fB\-maxsendbuffer=\fR<n>
.IP

.HP
\fB\-onlynet=\fR<net>
.IP
Make automatic outbound connections only to network <net> (ipv4, ipv6,
onion, i2p, cjdns). Inbound and manual connections are not

.HP
\fB\-peerbloomfilters\fR
.IP
Support filtering of blocks and transaction with bloom filters (default:

connecting to it. Use [host]:port notation for IPv6. Allowed
permissions: bloomfilter (allow requesting BIP37 filtered blocks
and transactions), noban (do not ban for misbehavior; implies
download), forcerelay (relay transactions that are already in the
mempool; implies relay), relay (relay even in \fB\-blocksonly\fR mode,
and unlimited transaction announcements), mempool (allow
requesting BIP35 mempool contents), download (allow getheaders
during IBD, no disconnect after maxuploadtarget limit), addr
(responses to GETADDR avoid hitting the cache and contain random
records with the most up\-to\-date info). Specify multiple

download,noban,mempool,relay). Can be specified multiple times.
.HP
\fB\-whitelist=\fR<[permissions@]IP address or network>

"bech32m", default: "bech32")
.HP
\fB\-avoidpartialspends\fR
.IP
Group outputs by address, selecting many (possibly all) or none, instead
of selecting on a per\-output basis. Privacy is improved as
addresses are mostly swept with fewer transactions and outputs
are aggregated in clean change addresses. It may result in higher
fees due to less optimal coin selection caused by this added
limitation and possibly a larger\-than\-necessary number of inputs
being used. Always enabled for wallets with "avoid_reuse"
enabled, otherwise default: 0.
.HP
\fB\-changetype\fR
.IP
What type of change to use ("legacy", "p2sh\-segwit", "bech32", or

.HP
\fB\-discardfee=\fR<amt>

discard up to the dust relay fee and a discard fee above that is
limited by the fee estimate for the longest target
.HP

.IP
Specify wallet path to load at startup. Can be used multiple times to
load multiple wallets. Path is to a directory containing wallet
data and log files. If the path is not absolute, it is
interpreted relative to <walletdir>. This only loads existing
wallets and does not create new ones. For backwards compatibility
this also accepts names of existing top\-level data files in
<walletdir>.
.HP
\fB\-walletbroadcast\fR
.IP
Make the wallet broadcast transactions (default: 1)
.HP
\fB\-walletdir=\fR<dir>
.IP
Specify directory to hold wallets (default: <datadir>/wallets if it

by TxID, %w is replaced by wallet name, %b is replaced by the
hash of the block including the transaction (set to 'unconfirmed'
if the transaction is not included) and %h is replaced by the
block height (\fB\-1\fR if not included). %w is not currently
implemented on windows. On systems where %w is supported, it
should NOT be quoted because this would break shell escaping used
to invoke the command.
