Print this help message and exit
-alertnotify=<cmd>
Execute command when a relevant alert is received or we see a really
long fork (%s in cmd is replaced by message)
-assumevalid=<hex>
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:

-blockfilterindex=<type>
Maintain an index of compact filters by block (default: 0, values:
basic). If <type> is not supplied or if <type> = 1, indexes for
all known types are enabled.
-blocknotify=<cmd>
Execute command when the best block changes (%s in cmd is replaced by
block hash)
-blockreconstructionextratxn=<n>
Extra transactions to keep in memory for compact block reconstructions
(default: 100)
-blocksdir=<dir>
Specify directory to hold blocks subdirectory for *.dat files (default:
<datadir>)
-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)
-coinstatsindex
Maintain coinstats index used by the gettxoutsetinfo RPC (default: 0)
-conf=<file>
Specify path to read-only configuration file. Relative paths will be
prefixed by datadir location. (default: bitcoin.conf)
-daemon
Run in the background as a daemon and accept commands (default: 0)
-daemonwait
Wait for initialization to be finished before exiting. This implies
-daemon (default: 0)
-datadir=<dir>
Specify data directory
-dbcache=<n>
Maximum database cache size <n> MiB (4 to 16384, default: 450). In
addition, unused mempool memory is shared for this cache (see
-maxmempool).
-debuglogfile=<file>
Specify location of debug log file. Relative paths will be prefixed by a
net-specific datadir location. (-nodebuglogfile to disable;
default: debug.log)
-includeconf=<file>
Specify additional configuration file, relative to the -datadir path
(only useable from configuration file, not command line)
-loadblock=<file>
Imports blocks from external file on startup
-maxmempool=<n>
Keep the transaction memory pool below <n> megabytes (default: 300)
-maxorphantx=<n>
Keep at most <n> unconnectable transactions in memory (default: 100)
-mempoolexpiry=<n>
Do not keep transactions in the mempool longer than <n> hours (default:
336)
-par=<n>
Set the number of script verification threads (-8 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=<file>
Specify pid file. Relative paths will be prefixed by a net-specific
datadir location. (default: bitcoind.pid)
-prune=<n>
Reduce storage requirements by enabling pruning (deleting) of old
blocks. This allows the pruneblockchain RPC to be called to
delete specific blocks, and enables automatic pruning of old
blocks if a target size in MiB is provided. This mode is
incompatible with -txindex and -coinstatsindex. 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)
-reindex
Rebuild chain state and block index from the blk*.dat files on disk
-reindex-chainstate
Rebuild chain state from the currently indexed blocks. When in pruning
mode or if blocks on disk might be corrupted, use full -reindex
instead.
-sandbox=<mode>
Use the experimental syscall sandbox in the specified mode
(-sandbox=log-and-abort or -sandbox=abort). Allow only expected
syscalls to be used by bitcoind. Note that this is an
experimental new feature that may cause bitcoind to exit or crash
unexpectedly: use with caution. In the "log-and-abort" mode the
invocation of an unexpected syscall results in a debug handler
being invoked which will log the incident and terminate the
program (without executing the unexpected syscall). In the
"abort" mode the invocation of an unexpected syscall results in
the entire process being killed immediately by the kernel without
executing the unexpected syscall.
-settings=<file>
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 bitcoin.conf instead for custom settings).
Relative paths will be prefixed by datadir location. (default:
settings.json)
-startupnotify=<cmd>
Execute command on startup.
-sysperms
Create new files with system default permissions, instead of umask 077
(only effective with disabled wallet functionality)
-txindex
Maintain a full transaction index, used by the getrawtransaction rpc
call (default: 0)
-version
Print version and exit
Connection options:
-addnode=<ip>
Add a node to connect to and attempt to keep the connection open (see
the addnode RPC help for more info). This option can be specified
multiple times to add multiple nodes; connections are limited to
8 at a time and are counted separately from the -maxconnections
limit.
-asmap=<file>
Specify asn mapping used for bucketing of the peers (default:
ip_asn.map). Relative paths will be prefixed by the net-specific
datadir location.
-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: 127.0.0.1:8334=onion, testnet: 127.0.0.1:18334=onion,
signet: 127.0.0.1:38334=onion, regtest: 127.0.0.1:18445=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
-fixedseeds
Allow fixed seeds if DNS seeds don't provide peers (default: 1)
-forcednsseed
Always query for peer addresses via DNS lookup (default: 0)
-i2pacceptincoming
If set and -i2psam is also set then incoming I2P connections are
accepted via the SAM proxy. If this is not set but -i2psam is set
then only outgoing connections will be made to the I2P network.
Ignored if -i2psam is not set. Listening for incoming I2P
connections is done through the SAM proxy, not by binding to a
local address and port (default: 1)
-i2psam=<ip:port>
I2P SAM proxy to reach I2P peers and accept I2P connections (default:
none)
-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 (default: 125). This limit
does not apply to connections manually added via -addnode or the
addnode RPC, which have a separate limit of 8.
-maxreceivebuffer=<n>
Maximum per-connection receive buffer, <n>*1000 bytes (default: 5000)
-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)
-networkactive
Enable all P2P network activity (default: 1). Can be changed by the
setnetworkactive RPC command
-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.
-peerblockfilters
Serve compact block filters to peers per BIP 157 (default: 0)
-peerbloomfilters
Support filtering of blocks and transaction with bloom filters (default:
0)
-permitbaremultisig
Relay non-P2SH multisig (default: 1)
-port=<port>
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).
-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 socket connection timeout in milliseconds. If an initial attempt
to connect is unsuccessful after this amount of time, drop it
(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)
-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,
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.
-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.
Debugging/Testing options:
-debug=<category>

ipc, leveldb, libevent, lock, mempool, mempoolrej, net, proxy,
prune, qt, rand, reindex, rpc, selectcoins, tor, util,
validation, walletdb, zmq. This option can be specified multiple
times to output multiple categories.
-debugexclude=<category>
Exclude debugging information for a category. Can be used in conjunction
with -debug=1 to output debug logs for all categories except the
specified category. This option can be specified multiple times
to exclude multiple categories.
-help-debug
Print help message with debugging options and exit
-logips
Include IP addresses in debug output (default: 0)
-logsourcelocations
Prepend debug output with name of the originating source location
(source file, line number and function name) (default: 0)
-logthreadnames
Prepend debug output with name of the originating thread (only available
on platforms supporting thread_local) (default: 0)
-logtimestamps
Prepend debug output with timestamp (default: 1)
-printtoconsole
Send trace/debug info to console (default: 1 when no -daemon. To disable
logging to file, set -nodebuglogfile)
-shrinkdebugfile
Shrink debug.log file on client startup (default: 1 when no -debug)

-datacarriersize
Maximum size of data in data carrier transactions we relay and mine
(default: 83)
-minrelaytxfee=<amt>
Fees (in BTC/kvB) 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

rpcuser=<USERNAME>/rpcpassword=<PASSWORD> pair of arguments. This
option can be specified multiple times
-rpcbind=<addr>[: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:

2>,...,<rpc n>. 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.
-server

编程接口
Bitcoin Core的API是一个JSON-RPC接口。 JSON代表JavaScript Object Notation，它可以很方便地呈现出人类和程序都可以轻松阅读的数据格式。 RPC代表远程过程调用，这意味着我们通过网络协议调用远程（位于Bitcoin Core节点）的程序（函数）。 这里的网络协议是HTTP或HTTPS（加密连接）。
使用curl 命令:
curl --user lvguidong:lvguidong --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getblockchaininfo", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:18443/
