flocore-node's Introduction

Flocore Node

A Florincoin blockchain indexing and query service. Intended to be used with as a Florincoin full node or in conjunction with a Florincoin full node.

Upgrading from previous versions of Flocore Node

There is no upgrade path from previous versions of Flocore Node due to the removal of the included Florincoin Core software. By installing this version, you must resynchronize the indexes from scratch.

Install

npm install
./bin/flocore-node start

Note: A default configuration file is placed in the flocore user's home directory (~/.flocore/flocore-node.json). Or, alternatively, you can copy the provided "flocore-node.json.sample" file to the project's root directory as flocore-node.json and edit it for your preferences. If you don't have a preferred block source (trusted peer), Bcoin will be started automatically and synchronized with the mainnet chain.

Prerequisites

Node.js v8.2.0+
~500GB of disk storage
~4GB of RAM

Configuration

The main configuration file is called "flocore-node.json". This file instructs flocore-node for the following options:

location of database files (datadir)
tcp port for web services, if configured (port)
florincoin network type (e.g. mainnet, testnet3, regtest), (network)
what services to include (services)
the services' configuration (servicesConfig)
