cjdcoind
cjdcoind is the primary full node CJD coin implementation, written in Go.
The CJD coin project is currently under active development and considered to be beta quality software.
In particular, the development branch of cjdcoind is highly experimental,
and should generally not be used in a production environment or on the
CJD coin mainnet.
cjdcoind is the primary mainnet node software for the CJD blockchain.
It is known to correctly download, validate, and serve the chain,
using rules for block acceptance based on Bitcoin Core, with the
addition of PacketCrypt Proofs.
It relays newly mined blocks, and individual transactions that have not yet made it into a block, as well as maintaining a transaction pool. All individual transactions admitted to the pool follow rules defined by the network operators, which include strict checks to filter transactions based on miner requirements ("standard" vs "non-standard" transactions).
Unlike other similar software, cjdcoind does NOT directly include wallet
functionality - this was an intentional design decision. You will not be
able to make or receive payments with cjdcoind directly.
Example wallet functionality is provided in the included, separate, pktwallet package.
Requirements
- Google Go (Golang) version 1.14 or higher.
- A somewhat recent release of Git.
Issue Tracker
- The GitHub integrated GitHub issue tracker is used for this project.
Building
Using git, clone the project from the repository:
git clone https://github.com/pkt-cash/cjdcoind
Use the ./do shell script to build cjdcoind, pktwallet, and pktctl.
NOTE: It is highly recommended to use only the toolchain Google distributes at the official Go homepage. Go toolchains provided by Linux distributions often use different defaults or apply non-standard patches to the official sources, usually to meet distribution-specific requirements (for example, Red Hat backports, security fixes, and provides a different default linker configuration vs. the upstream Google Go package.)
Support can only be provided for binaries compiled from unmodified sources, using the official (upstream) Google Golang toolchain. We unfortunately are unable to test and support every distribution specific combination.
The official Google Golang installer for Linux is always available for download here.
Documentation
The documentation for cjdcoind is work-in-progress, and available in the docs folder.

Overview ¶
cjdcoind is a full-node bitcoin implementation written in Go.
The default options are sane for most users. This means cjdcoind 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 cjdcoind starts up. By default, the configuration file is located at ~/.cjdcoind/cjdcoind.conf on POSIX-style operating systems and %LOCALAPPDATA%\cjdcoind\cjdcoind.conf on Windows. The -C (--configfile) flag, as shown below, can be used to override this location.
Usage:
cjdcoind [OPTIONS]
Application Options:
-V, --version Display version information and exit
-C, --configfile= Path to configuration file
-b, --datadir= Directory to store data
--logdir= Directory to log output.
-a, --addpeer= Add a peer to connect with at startup
--connect= Connect only to the specified peers at startup
--nolisten Disable listening for incoming connections -- NOTE:
Listening is automatically disabled if the --connect
option is used without also specifying listening
interfaces via --listen
--listen= Add an interface/port to listen for connections
(default all interfaces port: 8333, testnet: 18333)
--maxpeers= Max number of inbound and outbound peers (125)

--banduration= How long to ban misbehaving peers. Valid time units
are {s, m, h}. Minimum 1 second (24h0m0s)
--banthreshold= Maximum allowed ban score before disconnecting and
banning misbehaving peers.
--whitelist= Add an IP network or IP that will not be banned.
(eg. 192.168.1.0/24 or ::1)

-P, --rpcpass= Password for RPC connections
--rpclimituser= Username for limited RPC connections
--rpclimitpass= Password for limited RPC connections

--rpcmaxwebsockets= Max number of RPC websocket connections (25)
--rpcquirks Mirror some JSON-RPC quirks of Bitcoin Core -- NOTE:
Discouraged unless interoperability issues need to
be worked around
--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
--nodnsseed Disable DNS seeding for peers
--externalip= Add an ip to the list of local addresses we claim to
listen on to peers
--homedir= Creates this directory at startup
--testnet Use the test network
--regtest Use the regression test network
--simnet Use the simulation test network
--addcheckpoint= Add a custom checkpoint. Format: '<height>:<hash>'
--nocheckpoints Disable built-in checkpoints. Don't do this unless
you know what you're doing.
--uacomment= Comment to add to the user agent --
See BIP 14 for more information.
--dbtype= Database backend to use for the Block Chain (ffldb)
--profile= Enable HTTP profiling on given port -- NOTE port
must be between 1024 and 65536
--cpuprofile= Write CPU profile to the specified file
-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 (info)
--upnp Use UPnP to map our listening port outside of NAT
--minrelaytxfee= The minimum transaction fee in BTC/kB to be
considered a non-zero fee.
--limitfreerelay= Limit relay of transactions with no transaction fee
to the given amount in thousands of bytes per
minute (15)
--norelaypriority Do not require free or low-fee transactions to have
high priority for relaying
--maxorphantx= Max number of orphan transactions to keep in memory
(100)
--generate Generate (mine) bitcoins using the CPU
--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
--blockminsize= Mininum block size in bytes to be used when creating
a block
--blockmaxsize= Maximum block size in bytes to be used when creating
a block (750000)
--blockprioritysize= Size in bytes for high-priority/low-fee transactions
when creating a block (50000)
--nopeerbloomfilters Disable bloom filtering support.
--nocfilters Disable committed filtering (CF) support.
--sigcachemaxsize= The maximum number of entries in the signature
verification cache.
--blocksonly Do not accept transactions from remote peers.
--relaynonstd Relay non-standard transactions regardless of the
default settings for the active network.
--rejectnonstd Reject non-standard transactions regardless of the
default settings for the active network.
