To see only regular options, run `dimecoind --help`. ``` #### Options ```text -? Print this help message and exit -alertnotify= Execute command when an alert is raised (%s in cmd is replaced by message) -assumevalid= If this block is in the chain assume that it and its ancestors are valid and potentially skip their script verification (0 to verify all, default: 000000000000000c8b7a3bdcd8b9f516462122314529c8342244c685a4c899bf, testnet: 0000020c5e0f86f385cbf8e90210de9a9fd63633f01433bf47a6b3227a2851fd) -blocknotify= Execute command when the best block changes (%s in cmd is replaced by block hash) -blockreconstructionextratxn= Extra transactions to keep in memory for compact block reconstructions (default: 100) -blocksdir= Specify directory to hold blocks subdirectory for *.dat files (default: ) -blocksonly 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) -conf= Specify path to read-only configuration file. Relative paths will be prefixed by datadir location. (default: dimecoin.conf) -daemon Run in the background as a daemon and accept commands -datadir= Specify data directory -dbbatchsize Maximum database write batch size in bytes (default: 16777216) -dbcache= Maximum database cache size MiB (4 to 16384, default: 300). In addition, unused mempool memory is shared for this cache (see -maxmempool). -debuglogfile= Specify location of debug log file. Relative paths will be prefixed by a net-specific datadir location. (-nodebuglogfile to disable; default: debug.log) -includeconf= Specify additional configuration file, relative to the -datadir path (only useable from configuration file, not command line) -loadblock= Imports blocks from external file on startup -maxmempool= Keep the transaction memory pool below megabytes (default: 300) -mempoolexpiry= Do not keep transactions in the mempool longer than hours (default: 336) -minimumchainwork= Minimum work assumed to exist on a valid chain in hex (default: 000000000000000000000000000000000000000000008d970bc6cda0b02b30fc, testnet: 00000000000000000000000000000000000000000000000002d68d24632e300f) -par= Set the number of script verification threads (-16 to 15, 0 = auto, <0 = leave that many cores free, default: 0) -persistmempool Whether to save the mempool on shutdown and load on restart (default: 1) -pid= Specify pid file. Relative paths will be prefixed by a net-specific datadir location. (default: dimecoind.pid) -settings= Specify path to dynamic settings data file. Can be disabled with -nosettings. File is written at runtime and not meant to be edited by users (use dimecoin.conf instead for custom settings). Relative paths will be prefixed by datadir location. (default: settings.json) -sysperms Create new files with system default permissions, instead of umask 077 (only effective with disabled wallet functionality) -version Print version and exit ``` #### Connection Options ```text -addnode= 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= Threshold for disconnecting and discouraging misbehaving peers (default: 100) -bantime= Default duration (in seconds) of manually configured bans (default: 86400) -bind=[:][=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= 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= 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= Maintain at most connections to peers (temporary service connections excluded) (default: 125) -maxreceivebuffer= Maximum per-connection receive buffer, *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= Maximum per-connection send buffer, *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= 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= Use separate SOCKS5 proxy to reach peers via Tor onion services, set -noonion to disable (default: -proxy) -onlynet= Make outgoing connections only through network (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= Listen for connections on . 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= 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= Connect to a node to retrieve peer addresses, and disconnect. This option can be specified multiple times to connect to multiple nodes. -timeout= Specify connection timeout in milliseconds (minimum: 1, default: 5000) -torcontrol=: Tor control port to use if onion listening enabled (default: 127.0.0.1:9051) -torpassword= 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 ```text -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](../api/rpc-wallet.md#abandontransaction). ``` ```text -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= Set key pool size to (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= 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= 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 . 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 . -walletbackupsdir= Specify full path to directory for automatic wallet backups (must exist) -walletbroadcast Make the wallet broadcast transactions (default: 1) -walletdir= Specify directory to hold wallets (default: /wallets if it exists, otherwise ) -walletnotify= 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 ```text -discardfee= 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= 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= Fees (in DIME/kB) smaller than this are considered zero fee for transaction creation (default: 0.00001) -paytxfee= Fee (in DIME/kB) to add to transactions you send (default: 0.00) -txconfirmtarget= If paytxfee is not set, include enough fee so transactions begin confirmation on average within n blocks (default: 6) ``` #### HD Wallet Options ```text -sethdseed= 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) ``` #### ZeroMQ Notification Options ```text -zmqpubhashblock=
Enable publish hash block in
-zmqpubhashtx=

This is intended for regression testing tools and app development. Equivalent to -chain=regtest -testnet Use the test chain. Equivalent to -chain=test -vbparams=::(::(:::)) Use given start/end times for specified version bits deployment (regtest-only). Specifying window, threshold/thresholdstart, thresholdmin, falloffcoeff and mnactivation is optional. ``` #### Node Relay Options ```text -acceptnonstdtxn Relay and mine "non-standard" transactions (testnet/regtest only; default: 1) -bytespersigop Equivalent bytes per sigop in transactions for relay and mining (default: 20) -datacarrier Relay and mine data carrier transactions (default: 1) -datacarriersize Maximum size of data in data carrier transactions we relay and mine (default: 83) -dustrelayfee= Fee rate (in DIME/kB) used to define dust, the value of an output such that it will cost more than its value in fees at this fee rate to spend it. (default: 0.00003) -incrementalrelayfee= Fee rate (in DIME/kB) used to define cost of relay, used for mempool limiting and BIP 125 replacement. (default: 0.00001) -minrelaytxfee= Fees (in DIME/kB) smaller than this are considered zero fee for relaying, mining and transaction creation (default: 0.00001) -whitelistforcerelay Add 'forcerelay' permission to whitelisted inbound peers with default permissions. This will relay transactions even if the transactions were already in the mempool. (default: 0) -whitelistrelay Add 'relay' permission to whitelisted inbound peers with default permissions.

(default: 0.00001) -blockversion= Override block version to test forking scenarios ``` #### RPC Server Options ```text -rest Accept public REST requests (default: 0) -rpcallowip= Allow JSON-RPC connections from specified source. Valid for are a single IP (e.g. 1.2.3.4), a network/netmask (e.g. 1.2.3.4/255.255.255.0) or a network/CIDR (e.g. 1.2.3.4/24). This option can be specified multiple times -rpcauth= Username and HMAC-SHA-256 hashed password for JSON-RPC connections. The field comes in the format: :$. A canonical python script is included in share/rpcuser. The client then connects normally using the rpcuser=/rpcpassword= pair of arguments. This option can be specified multiple times -rpcbind=[:port] Bind to given address to listen for JSON-RPC connections. Do not expose the RPC server to untrusted networks such as the public internet! This option is ignored unless -rpcallowip is also passed. Port is optional and overrides -rpcport. Use [host]:port notation for IPv6. This option can be specified multiple times (default: 127.0.0.1 and ::1 i.e., localhost, or if -rpcallowip has been specified, 0.0.0.0 and :: i.e., all addresses) -rpccookiefile= Location of the auth cookie. Relative paths will be prefixed by a net-specific datadir location. (default: data dir) -rpcpassword= Password for JSON-RPC connections -rpcport= Listen for JSON-RPC connections on (default: 9998, testnet: 19998, regtest: 19898) -rpcservertimeout= Timeout during HTTP requests (default: 30) -rpcthreads= Set the number of threads to service RPC calls (default: 4) -rpcuser= Username for JSON-RPC connections -rpcwhitelist= Set a whitelist to filter incoming RPC calls for a specific user. The field comes in the format: :,,...,. If multiple whitelists are set for a given user, they are set-intersected. See -rpcwhitelistdefault documentation for information on default whitelist behavior. -rpcwhitelistdefault Sets default behavior for rpc whitelisting. Unless rpcwhitelistdefault is set to 0, if any -rpcwhitelist is set, the rpc server acts as if all rpc users are subject to empty-unless-otherwise-specified whitelists. If rpcwhitelistdefault is set to 1 and no -rpcwhitelist is set, rpc server acts as if all rpc users are subject to empty whitelists. -rpcworkqueue= Set the depth of the work queue to service RPC calls (default: 16) -server Accept command line and JSON-RPC commands ``` #### Wallet Debugging/Testing Options ```{note} These options are normally hidden and will only be shown if using the help debug option: `dimecoind --held -help-debug` ``` ```text -dblogsize= Flush wallet database activity from memory to disk log every megabytes (default: 100) -flushwallet Run a thread to flush wallet periodically (default: 1) -privdb Sets the DB_PRIVATE flag in the wallet db environment (default: 1) -walletrejectlongchains Wallet will not create transactions that violate mempool chain limits (default: 0) ``` ### Network Dependent Options The following options can only be used for specific network types. These options are provided support development (devnet) and regression test (regtest) networks. #### Regtest Options ```text -vbparams=::(::(:::)) Use given start/end times for specified version bits deployment (regtest-only). Specifying window, threshold/thresholdstart, thresholdmin, falloffcoeff and mnactivation is optional. ```
