btcd is a full-node bitcoin implementation written in Go.
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:
'<height>:<hash>'
-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= Mininum 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= Mininum 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
<subsystem>=<level>,<subsystem2>=<level>,... 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)
--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
