The API is equivalent to the API document here.The methods are exposed as lower camelcase methods on the bitcoin.Client object, or you may call the API directly using the cmd method.This module uses callbacks, which is the prevalent way to work with asynchronous functions in Node.js.If you'd like to instead use promises, then please see the bitcoin-promise module.Install npm install bitcoin Examples Create client Get balance across all accounts with minimum confirmations of 6 Getting the balance directly using cmd Batch multiple RPC calls into single HTTP request SSL See Enabling SSL on original client.If you're using this to connect to bitcoind across a network it is highly recommended to enable ssl, otherwise an attacker may intercept your RPC credentials resulting in theft of your bitcoins.When enabling ssl by setting the configuration option to true, the sslStrict option (verifies the server certificate) will also be enabled by default.

It is highly recommended to specify the sslCa as well, even if your bitcoind has a certificate signed by an actual CA, to ensure you are connecting to your own bitcoind.Bitcore is a full bitcoin node — your apps run directly on the peer-to-peer network.For wallet application development, additional indexes have been added into Bitcoin for querying address balances, transaction history, and unspent outputs.Open SourceBitcore is 100% open source, powered by the time-tested and battle-hardened Bitcore Library.Apps built on Bitcore benefit from the extensive testing and review of dozens of bitcoin companies and community contributors.Full-Featured & ExtensibleBitcore provides a powerful blockchain API and the Insight blockchain explorer, right out of the box.A modular, service-based architecture makes Bitcore a perfect platform for enterprise applications.Built on BitcoindTo build reliable bitcoin and blockchain-based applications, compatibility with Bitcoin is essential.Bitcore uses the source code of Bitcoin directly, so accidental chain forks are a thing of the past.
