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
If enabled, wipe chain state and block index, and rebuild them from
blk*.dat files on disk. Also wipe and rebuild other optional

its chainstate will be wiped as well. The snapshot can then be
reloaded via RPC.
.HP
\fB\-reindex\-chainstate\fR
.IP
If enabled, wipe chain state, and rebuild it from blk*.dat files on
disk. If an assumeutxo snapshot was loaded, its chainstate will
be wiped as well. The snapshot can then be reloaded via RPC.

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).

signet: 127.0.0.1:38334=onion, regtest: 127.0.0.1:18445=onion)
.HP
\fB\-cjdnsreachable\fR
.IP

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

.HP
\fB\-peerbloomfilters\fR
.IP
Support filtering of blocks and transaction with bloom filters (default:
0)
.HP
\fB\-port=\fR<port>
.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
the same permissions as \fB\-whitebind\fR. Can be specified multiple
times.
.PP

"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
\fB\-consolidatefeerate=\fR<amt>
.IP

more inputs than strictly necessary so that the wallet's UTXO
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
