Querying addresses that have millions of transactions is supported however takes hundreds of seconds to fully calculate the balance. Creating a cache of previous results wasn't currently working because the `isSpent` query is always based on the current bitcoind tip. Thus the balance of the outputs would be included however wouldn't be removed when spent as the output wouldn't be checked again when querying for blocks past the last checkpoint. Including the satoshis in the inputs address index would make it possible to subtract the spent amount, however this degrades optimizations elsewhere. The syncing times or querying for addresses with 10,000 transactions per address. It may preferrable to have an additional address service that handles high-volume addresses be on an opt-in basis so that a custom running client could select high volume addresses to create optimizations for querying balances and history. The strategies for creating indexes differs on these use cases. |

Bitcore Node
A Bitcoin full node for building applications and services with Node.js. A node is extensible and can be configured to run additional services. At the minimum a node has native bindings to Bitcoin Core with the Bitcoin Service. Additional services can be enabled to make a node more useful such as exposing new APIs, adding new indexes for addresses with the Address Service, running a block explorer, wallet service, and other customizations.
Install
npm install -g bitcore-node
bitcore-node start
Note: For your convenience, we distribute binaries for x86_64 Linux and x86_64 Mac OS X. Upon npm install, the binaries for your platform will be downloaded. For more detailed installation instructions, or if you want to compile the project yourself, then please see the Build & Install documentation to build the project from source.
Prerequisites
- Node.js v0.12 or v4.2
- ~100GB of disk storage
- ~4GB of RAM
- Mac OS X >= 10.9, Ubuntu >= 12.04 (libc >= 2.15 and libstdc++ >= 6.0.16)
Configuration
Bitcore includes a Command Line Interface (CLI) for managing, configuring and interfacing with your Bitcore Node.
bitcore-node create -d <bitcoin-data-dir> mynode
cd mynode
bitcore-node install <service>
bitcore-node install https://github.com/yourname/helloworld
This will create a directory with configuration files for your node and install the necessary dependencies. For more information about (and developing) services, please see the Service Documentation.
To start bitcore-node as a daemon:
bitcore-node start --daemon
Add-on Services
