Connection Options#
-addnode=<ip>
Add a node to connect to and attempt to keep the connection open (see
the `addnode` RPC command help for more info). This option can be
specified multiple times to add multiple nodes.
-banscore=<n>
Threshold for disconnecting and discouraging misbehaving peers (default:
100)
-bantime=<n>
Default duration (in seconds) of manually configured bans (default:
86400)
-bind=<addr>[:<port>][=onion]
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: 127.0.0.1:11391=onion, testnet: 127.0.0.1:21931=onion,
regtest: 127.0.0.1:31931=onion)
-connect=<ip>
Connect only to the specified node; -noconnect disables automatic
connections (the rules for this peer are the same as for
-addnode). This option can be specified multiple times to connect
to multiple nodes.
-discover
Discover own IP addresses (default: 1 when listening and no -externalip
or -proxy)
-dns
Allow DNS lookups for -addnode, -seednode and -connect (default: 1)
-dnsseed
Query for peer addresses via DNS lookup, if low on addresses (default: 1
unless -connect used)
-externalip=<ip>
Specify your own public address
-forcednsseed
Always query for peer addresses via DNS lookup (default: 0)
-listen
Accept connections from outside (default: 1 if no -proxy or -connect)
-listenonion
Automatically create Tor onion service (default: 1)
-maxconnections=<n>
Maintain at most <n> connections to peers (temporary service connections
excluded) (default: 125)
-maxreceivebuffer=<n>
Maximum per-connection receive buffer, <n>*1000 bytes (default: 5000) The buffer is used to temporarily store incoming data from peers on the network until it can be processed. Increasing the maxreceivebuffer size might be useful in scenarios where nodes are on high-speed networks and can handle larger volumes of incoming data without becoming a bottleneck. It could potentially improve the speed at which data is processed from peers, assuming the node's hardware is capable of handling the increased load.
Conversely, decreasing this value might help in constrained environments where memory is limited, or where there is a need to limit the node's resource usage. However, setting it too low could negatively impact the node's ability to process incoming data efficiently, possibly slowing down synchronization with the network or the propagation of transactions and blocks.
-maxsendbuffer=<n>
Maximum per-connection send buffer, <n>*1000 bytes (default: 1000)
-maxtimeadjustment
Maximum allowed median peer time offset adjustment. Local perspective of
time may be influenced by peers forward or backward by this
amount. (default: 4200 seconds)
-maxuploadtarget=<n>
Tries to keep outbound traffic under the given target (in MiB per 24h).
Limit does not apply to peers with 'download' permission. 0 = no
limit (default: 0)
-onion=<ip:port>
Use separate SOCKS5 proxy to reach peers via Tor onion services, set
-noonion to disable (default: -proxy)
-onlynet=<net>
Make outgoing connections only through network <net> (ipv4, ipv6, onion,
i2p). Incoming connections are not affected by this option. This
option can be specified multiple times to allow multiple
networks. Warning: if it is used with non-onion networks and the
-onion or -proxy option is set, then outbound onion connections
will still be made; use -noonion or -onion=0 to disable outbound
onion connections in this case.
-peerbloomfilters
Support filtering of blocks and transaction with bloom filters (default:
1)
-permitbaremultisig
Relay non-P2SH multisig (default: 1)
-port=<port>
Listen for connections on <port>. Nodes not using the default ports
(default: 9999, testnet: 19999, regtest: 19899) are unlikely to
get incoming connections. Not relevant for I2P (see doc/i2p.md).
-proxy=<ip:port>
Connect through SOCKS5 proxy, set -noproxy to disable (default:
disabled)
-proxyrandomize
Randomize credentials for every proxy connection. This enables Tor
stream isolation (default: 1)
-seednode=<ip>
Connect to a node to retrieve peer addresses, and disconnect. This
option can be specified multiple times to connect to multiple
nodes.
-timeout=<n>
Specify connection timeout in milliseconds (minimum: 1, default: 5000)
-torcontrol=<ip>:<port>
Tor control port to use if onion listening enabled (default:
127.0.0.1:9051)
-torpassword=<pass>
Tor control port password (default: empty)
-upnp
Use UPnP to map the listening port (default: 0)
-whitebind=<[permissions@]addr>
Bind to the given address and add permission flags to the peers
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 -blocksonly mode),
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.
-whitelist=<[permissions@]IP address or network>
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 -whitebind. Can be specified multiple
times.
Indexing Options#
-reindex
Rebuild chain state and block index from the blk*.dat files on disk
-reindex-chainstate
Rebuild chain state from the currently indexed blocks. If blocks on disk might be corrupted, use full -reindex
instead.
-txindex
Maintain a full transaction index, used by the getrawtransaction rpc
call (default: 1)
Wallet Options#
Attention
Dimecoin Core will remove the -zapwallettxes startup option and its functionality in a future release. This option was originally intended to allow for the fee bumping of transactions that did not signal RBF. This functionality will be superceded by the abandon transaction capability.
-avoidpartialspends
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.
-disablewallet
Do not load the wallet and disable wallet RPC calls
-keypool=<n>
Set key pool size to <n> (default: 1000). Warning: Smaller sizes may
increase the risk of losing funds when restoring from an old
backup, if none of the addresses in the original keypool have
been used.
-rescan=<mode>
Rescan the block chain for missing wallet transactions on startup (1 =
start from wallet creation time, 2 = start from genesis block)
-spendzeroconfchange
Spend unconfirmed change when sending transactions (default: 1)
-wallet=<path>
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>.
-walletbackupsdir=<dir>
Specify full path to directory for automatic wallet backups (must exist)
-walletbroadcast
Make the wallet broadcast transactions (default: 1)
-walletdir=<dir>
Specify directory to hold wallets (default: <datadir>/wallets if it
exists, otherwise <datadir>)
-walletnotify=<cmd>
Execute command when a wallet transaction changes. %s in cmd is replaced
by TxID and %w is replaced by wallet name. %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.
Wallet Fee Options#
-discardfee=<amt>
The fee rate (in DIME/kB) 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
-fallbackfee=<amt>
A fee rate (in DIME/kB) that will be used when fee estimation has
insufficient data. 0 to entirely disable the fallbackfee feature.
(default: 0.00001)
-mintxfee=<amt>
Fees (in DIME/kB) smaller than this are considered zero fee for
transaction creation (default: 0.00001)
-paytxfee=<amt>
Fee (in DIME/kB) to add to transactions you send (default: 0.00)
-txconfirmtarget=<n>

confirmation on average within n blocks (default: 6)
HD Wallet Options#
-sethdseed=<hex>
User defined seed for HD wallet (should be in hex). Only has effect
during wallet creation/first start (default: randomly generated)
-usehd
Use hierarchical deterministic key generation (HD) after BIP39/BIP44.
Only has effect during wallet creation/first start (default: 0)
