<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

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

.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 (default: debug.log). Relative paths
will be prefixed by a net\-specific datadir location. Pass
\fB\-nodebuglogfile\fR to disable writing the log to a file.
.HP
\fB\-includeconf=\fR<file>

.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\-shutdownnotify=\fR<cmd>
.IP
Execute command immediately before beginning shutdown. The need for
shutdown may be urgent, so be careful not to delay it long (if
the command doesn't require interaction with the server, consider
having it fork into the background).
.HP
\fB\-startupnotify=\fR<cmd>
.IP
Execute command on startup.
.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

.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

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

.IP
Serve compact block filters to peers per BIP 157 (default: 0)
.HP
\fB\-peerbloomfilters\fR
.IP
Support filtering of blocks and transaction with bloom filters (default:

.IP
Listen for connections on <port>. Nodes not using the default ports
(default: 8333, testnet: 18333, signet: 38333, regtest: 18444)
are unlikely to get incoming connections. Not relevant for I2P
(see doc/i2p.md).
.HP
\fB\-proxy=\fR<ip:port>
.IP
Connect through SOCKS5 proxy, set \fB\-noproxy\fR to disable (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
permissions separated by commas (default:
download,noban,mempool,relay). Can be specified multiple times.
.HP
\fB\-whitelist=\fR<[permissions@]IP address or network>
.IP
Add permission flags to the peers connecting from the given IP address
(e.g. 1.2.3.4) or CIDR\-notated network (e.g. 1.2.3.0/24). Uses

"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
"bech32m"). Default is "legacy" when \fB\-addresstype\fR=\fI\,legacy\/\fR, else it
is an implementation detail.
.HP

pool can be reduced (default: 0.0001).
.HP
\fB\-disablewallet\fR
.IP
Do not load the wallet and disable wallet RPC calls
.HP
\fB\-discardfee=\fR<amt>
.IP
The fee rate (in BTC/kvB) that indicates your tolerance for discarding
change by adding it to the fee (default: 0.0001). Note: An output
is discarded if it is dust at this rate, but we will always
discard up to the dust relay fee and a discard fee above that is
limited by the fee estimate for the longest target
.HP
\fB\-fallbackfee=\fR<amt>
.IP
A fee rate (in BTC/kvB) that will be used when fee estimation has
insufficient data. 0 to entirely disable the fallbackfee feature.
(default: 0.00)
.HP
\fB\-keypool=\fR<n>

increase the risk of losing funds when restoring from an old
backup, if none of the addresses in the original keypool have
been used.
.HP
\fB\-maxapsfee=\fR<n>
.IP
Spend up to this amount in additional (absolute) fees (in BTC) if it
allows the use of partial spend avoidance (default: 0.00)
.HP
\fB\-mintxfee=\fR<amt>
.IP
Fee rates (in BTC/kvB) smaller than this are considered zero fee for
transaction creation (default: 0.00001)
.HP
\fB\-paytxfee=\fR<amt>
.IP
Fee rate (in BTC/kvB) to add to transactions you send (default: 0.00)

.IP
If paytxfee is not set, include enough fee so transactions begin
confirmation on average within n blocks (default: 6)
.HP
\fB\-wallet=\fR<path>
.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
exists, otherwise <datadir>)
.HP
\fB\-walletnotify=\fR<cmd>
.IP
Execute command when a wallet transaction changes. %s in cmd is replaced
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.
.HP
\fB\-walletrbf\fR
