The default options are sane for most users. This means btcd will work 'out of the box' for most users. However, there are also a wide variety of flags that can be used to control it. The following section provides a usage overview which enumerates the flags. An interesting point to note is that the long form of all of these options (except -C) can be specified in a configuration file that is automatically parsed when btcd starts up. By default, the configuration file is located at ~/.btcd/btcd.conf on POSIX-style operating systems and %LOCALAPPDATA%\btcd\btcd.conf on Windows. The -C (--configfile) flag, as shown below, can be used to override this location. Usage: btcd [OPTIONS] Application Options: --addcheckpoint= Add a custom checkpoint. Format: ':' -a, --addpeer= Add a peer to connect with at startup --addrindex Maintain a full address-based transaction index which makes the searchrawtransactions RPC available --banduration= How long to ban misbehaving peers. Valid time units are {s, m, h}. Minimum 1 second (default: 24h0m0s) --banthreshold= Maximum allowed ban score before disconnecting and banning misbehaving peers. (default: 100) --blockmaxsize= Maximum block size in bytes to be used when creating a block (default: 750000) --blockminsize= Minimum block size in bytes to be used when creating a block --blockmaxweight= Maximum block weight to be used when creating a block (default: 3000000) --blockminweight= Minimum block weight to be used when creating a block --blockprioritysize= Size in bytes for high-priority/low-fee transactions when creating a block (default: 50000) --blocksonly Do not accept transactions from remote peers. -C, --configfile= Path to configuration file --connect= Connect only to the specified peers at startup --cpuprofile= Write CPU profile to the specified file -b, --datadir= Directory to store data --dbtype= Database backend to use for the Block Chain (default: ffldb) -d, --debuglevel= Logging level for all subsystems {trace, debug, info, warn, error, critical} -- You may also specify =,=,... to set the log level for individual subsystems -- Use show to list available subsystems (default: info) --dropaddrindex Deletes the address-based transaction index from the database on start up and then exits. --dropcfindex Deletes the index used for committed filtering (CF) support from the database on start up and then exits. --droptxindex Deletes the hash-based transaction index from the database on start up and then exits. --externalip= Add an ip to the list of local addresses we claim to listen on to peers --generate Generate (mine) bitcoins using the CPU --limitfreerelay= Limit relay of transactions with no transaction fee to the given amount in thousands of bytes per minute (default: 15) --listen= Add an interface/port to listen for connections (default all interfaces port: 8333, testnet: 18333, signet: 38333) --logdir= Directory to log output --maxorphantx= Max number of orphan transactions to keep in memory (default: 100) --maxpeers= Max number of inbound and outbound peers (default: 125) --miningaddr= Add the specified payment address to the list of addresses to use for generated blocks -- At least one address is required if the generate option is set --minrelaytxfee= The minimum transaction fee in BTC/kB to be considered a non-zero fee. (default: 1e-05) --nobanning Disable banning of misbehaving peers --nocfilters Disable committed filtering (CF) support --nocheckpoints Disable built-in checkpoints. Don't do this unless you know what you're doing. --nodnsseed Disable DNS seeding for peers --nolisten Disable listening for incoming connections -- NOTE: Listening is automatically disabled if the --connect or --proxy options are used without also specifying listen interfaces via --listen --noonion Disable connecting to tor hidden services --nopeerbloomfilters Disable bloom filtering support --norelaypriority Do not require free or low-fee transactions to have high priority for relaying --norpc Disable built-in RPC server -- NOTE: The RPC server is disabled by default if no rpcuser/rpcpass or rpclimituser/rpclimitpass is specified --notls Disable TLS for the RPC server -- NOTE: This is only allowed if the RPC server is bound to localhost --onion= Connect to tor hidden services via SOCKS5 proxy (eg. 127.0.0.1:9050) --onionpass= Password for onion proxy server --onionuser= Username for onion proxy server --profile= Enable HTTP profiling on given port -- NOTE port must be between 1024 and 65536 --proxy= Connect via SOCKS5 proxy (eg. 127.0.0.1:9050) --proxypass= Password for proxy server --proxyuser= Username for proxy server --regtest Use the regression test network --rejectnonstd Reject non-standard transactions regardless of the default settings for the active network. --relaynonstd Relay non-standard transactions regardless of the default settings for the active network. --rpccert= File containing the certificate file --rpckey= File containing the certificate key --rpclimitpass= Password for limited RPC connections --rpclimituser= Username for limited RPC connections --rpclisten= Add an interface/port to listen for RPC connections (default port: 8334, testnet: 18334) --rpcmaxclients= Max number of RPC clients for standard connections (default: 10) --rpcmaxconcurrentreqs= Max number of concurrent RPC requests that may be processed concurrently (default: 20) --rpcmaxwebsockets= Max number of RPC websocket connections (default: 25) --rpcquirks Mirror some JSON-RPC quirks of Bitcoin Core -- NOTE: Discouraged unless interoperability issues need to be worked around -P, --rpcpass= Password for RPC connections -u, --rpcuser= Username for RPC connections --sigcachemaxsize= The maximum number of entries in the signature verification cache (default: 100000) --simnet Use the simulation test network --testnet Use the test network --torisolation Enable Tor stream isolation by randomizing user credentials for each connection. --trickleinterval= Minimum time between attempts to send new inventory to a connected peer (default: 10s) --txindex Maintain a full hash-based transaction index which makes all transactions available via the getrawtransaction RPC --uacomment= Comment to add to the user agent -- See BIP 14 for more information. --upnp Use UPnP to map our listening port outside of NAT -V, --version Display version information and exit --whitelist= Add an IP network or IP that will not be banned.
