A list of some frequently needed Litecoin commands for my reference for use with litecoin-cli on Linux. Get the details for a particular LTC transaction including the amount, the fee, time received, whether it was sent or received, among numerous other details this is for your own transactions, though :.

Always copy the key to a USB drive that is not used by you or anyone else, and stow it away in a safe place. Note that if you encrypted your wallet with a password, you will need to unlock it before exporting your private key. One way to do it is by typing the following:.

You will need to clear its history for security purposes. One way you can do that on Linux is by typing. Get info about a particular block such as the transactions it contains, block height, block size, confirmations, among other things:. It also has a params field in which you coud put the username:. In order to connect on the same machine, you may want to add the following lines to allow connections from localhost:. Sign in Join. Sign in. Log into your account.

They are completely compatible with each other, they take the same command-line arguments, read the same configuration file, and read and write the same data files. You can run only one copy of either litecoin-qt or litecoind on your system at a time.

If you accidentally try to launch two copies, the most recently opened copy will let you know that one is already running and it will exit. The simplest way to start from scratch with the command line client--automatically syncing the blockchain and creating a wallet--is to save the binary and just run this command without arguments from the directory containing the downloaded litecoind binary:.

This version of the litecoin binary runs in the background after you call it for the first time. It is a 'headless' server which you can query with subsequent calls from the command line, and can be stopped through a command line argument such as:.

While litecoind is running, the -? All command-line options except for -datadir and -conf may be specified in a configuration file, and all configuration file options may also be specified on the command line. Command-line options override values set in the configuration file. The configuration file is not automatically created; you can create it using your favorite plain-text editor. By default, the Litecoin binary will look for a file named litecoin. Note: if running Litecoin in testnet mode, the sub-folder "testnet" will be appended to the data directory automatically.

This makes the RPC interface implicitly versioned on the major version. The version tuple can be retrieved by e. The release notes of a new major release come with detailed instructions on what RPC features were deprecated and how to re-enable them temporarily.

The RPC interface allows other programs to control Bitcoin Core, including the ability to spend funds from your wallets, affect consensus verification, read private data, and otherwise perform operations that can cause loss of money, data, or privacy. This section suggests how you should use and configure Bitcoin Core to reduce the risk that its RPC interface will be abused.

Securing the executable: Anyone with physical or remote access to the computer, container, or virtual machine running Bitcoin Core can compromise either the whole program or just the RPC interface. This includes being able to record any passphrases you enter for unlocking your encrypted wallets or changing settings so that your Bitcoin Core program tells you that certain transactions have multiple confirmations even when they aren't part of the best block chain.

For this reason, you should not use Bitcoin Core for security sensitive operations on systems you do not exclusively control, such as shared computers or virtual private servers. Securing local network access: By default, the RPC interface can only be accessed by a client running on the same computer and only after the client provides a valid authentication credential username and passphrase. Any program on your computer with access to the file system and local network can obtain this level of access.

Additionally, other programs on your computer can attempt to provide an RPC interface on the same port as used by Bitcoin Core in order to trick you into revealing your authentication credentials.

For this reason, it is important to only use Bitcoin Core for security-sensitive operations on a computer whose other programs you trust.

Securing remote network access: You may optionally allow other computers to remotely control Bitcoin Core by setting the rpcallowip and rpcbind configuration parameters. These settings are only meant for enabling connections over secure private networks or connections that have been otherwise secured e. Do not enable RPC connections over the public Internet. Although Bitcoin Core's RPC interface does use authentication, it does not use encryption, so your login credentials are sent as clear text that can be read by anyone on your network path.

Additionally, the RPC interface has not been hardened to withstand arbitrary Internet traffic, so changing the above settings to expose it to the Internet even using something like a Tor hidden service could expose you to unconsidered vulnerabilities. See bitcoind -help for more information about these settings and other settings described in this document.

The default way to do this in Docker also exposes the port to the public Internet. Instead, expose it only on the host system's localhost, for example: -p Secure authentication: By default, Bitcoin Core generates unique login credentials each time it restarts and puts them into a file readable only by the user that started Bitcoin Core, allowing any of that user's RPC clients with read access to the file to login automatically.

The file is. As a final fallback, you can directly use manually-chosen rpcuser and rpcpassword configuration parametersbut you must ensure that you choose a strong and unique passphrase and still don't use insecure networks, as mentioned above.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

It is one of the main components of the Bitcoin network node software. Bitcoin software exists in two forms: a GUI application and a background application daemon on Unix, service on Windows.

This is a full-fledged bitcoin node that downloads the entire transaction history blockchain and processes transactions. Bitcoind is somewhat limited in functionality, for example, it cannot give you transaction history at an address that you did not import in advance. However, it provides a fairly powerful interface for the programmer.

Bitcoin software has both a graphical interface called bitcoin-qt and a console interface, bitcoind. If the first is convenient for human use, then without a text it is quite difficult to make an online store or any other service that accepts bitcoins as a payment. About it and speech will go. To work you need to run one instance of bitcoin as a daemon, so he worked as a full-fledged host on the network and give commands to it using another copy of bitcoind.

If you do not have such a file you need to create it. There you can register and other settings from those given when starting the daemon. Accordingly, the only thing you need to accept bitcoins is a bitcoin client on the server. All that remains after installation is to set up the client and Node. Next, you need to configure the client, create daemon in order to run bitcoind in the background.

Now daemon is created to run in the background:. Reboot daemon configuration:. There are now two ways to interact with the bitcoind daemon to force it to execute user commands. For example:. This is a common interface that allows you to connect to bitcoind and execute commands from any language - and possibly even from another computer.

For brevity, only two are listed. Download the program you can on bitcoin.Run bitcoind or bitcoin-qt -server. You must create a bitcoin. A list of RPC calls will be shown. If you are learning the API, it is a very good idea to use the test network run bitcoind -testnet and bitcoin-cli -testnet. Running Bitcoin with the -server argument or running bitcoind tells it to function as a HTTP JSON-RPC server, but Basic access authentication must be used when communicating with it, and, for security, by default, the server only accepts connections from other processes on the same machine.

See the rpcssl wiki page for setup instructions and a list of all bitcoin. Allowing arbitrary machines to access the JSON-RPC port using the rpcallowip configuration option is dangerous and strongly discouraged -- access should be strictly limited to trusted machines.

To access the server you should find a suitable library for your language. See the proper money handling page for notes on avoiding rounding errors when handling bitcoin values. It automatically generates Python methods for RPC calls.

However, due to its design for supporting old versions of Python, it is also rather inefficient. Generally, this version is recommended.

While BitcoinRPC lacks a few obscure features from jsonrpc, software using only the ServiceProxy class can be written the same to work with either version the user might choose to install:.

For example:. Note: The jsonRPCClient library uses fopen and will throw an exception saying "Unable to connect" if it receives a or error from bitcoind. This prevents you from being able to see error messages generated by bitcoind as they are sent with status or You must set the client's credentials; for example:. The btcrpcclient package can be used to communicate with Bitcoin. You must provide credentials to match the client you are communicating with. A library for serializing and deserializing Json will make your life a lot easier:.

There is also a wrapper for Json. Querying the daemon with BitcoinLib is as simple as:. Bitcoin Knots 0. Multi-wallet can be enabled by using more than one -wallet argument when starting Bitcoin, either on the command line or in the Bitcoin config file.The Developer Reference aims to provide technical details and API information to help you start building Bitcoin-based applications, but it is not a specification.

To make the best use of this documentation, you may want to install the current version of Bitcoin Core, either from source or from a pre-compiled executable. Questions about Bitcoin development are best asked in one of the Bitcoin development communities. Errors or suggestions related to documentation on Bitcoin. If you hover your mouse over a paragraph, cross-reference links will be shown in blue. If you hover over a cross-reference link, a brief definition of the term will be displayed in a tooltip.

The Bitcoin. Bitcoin security depends on consensus. Should your program diverge from consensusits security is weakened or destroyed. The specific cause will not matter to the users of your software whose wealth is lost.

The only correct specification of consensus behavior is the actual behavior of programs on the network which maintain consensus. As that behavior is subject to arbitrary inputs in a large variety of unique environments, it cannot ever be fully documented here or anywhere else. However, the Bitcoin Core developers are working on making their consensus code portable so other implementations can use it. Bitcoin Core 0.

Future versions of Bitcoin Core also provided consensus code that is more complete, more portable, and more consistent in diverse environments. In addition, we also warn you that this documentation has not been extensively reviewed by Bitcoin experts and so likely contains numerous errors. At the bottom of the menu on the left, you will find links that allow you to report an issue or to edit the documentation on GitHub. Please use those links if you find any errors or important missing information.

The hashes are in internal byte order ; the other values are all in little-endian order. An example header in hex:. Version 1 was introduced in the genesis block January Version 2 was introduced in Bitcoin Core 0. As described in BIP34valid version 2 blocks require a block height parameter in the coinbase. Also described in BIP34 are rules for rejecting certain blocks ; based on those rules, Bitcoin Core 0.

Version 3 blocks were introduced in Bitcoin Core 0.

Transactions that do not use strict DER encoding had previously been non-standard since Bitcoin Core 0. The mechanism used for the version 2, 3, and 4 upgrades is commonly called IsSuperMajority after the function added to Bitcoin Core to manage those soft forking changes.

See BIP34 for a full description of this method. Draft BIP9 describes the version bits design as of this writing, although it is still being actively edited and may substantially change while in the draft state. The merkle root is constructed using all the TXIDs of transactions in this blockbut first the TXIDs are placed in order as required by the consensus rules :.

Any input within this block can spend an output which also appears in this block assuming the spend is otherwise valid. This ensures that any program parsing block chain transactions linearly will encounter each output before it is used as an input.

If a block only has a coinbase transactionthe coinbase TXID is used as the merkle root hash. If a block only has a coinbase transaction and one other transaction, the TXIDs of those two transactions are placed in order, concatenated as 64 raw bytes, and then SHA SHA hashed together to form the merkle root.

If a block has three or more transactions, intermediate merkle tree rows are formed. If there are more than two hashes in the second row, the process is repeated to create a third row and, if necessary, repeated further to create additional rows.
