This tutorial will go over the basics of spinning up a Bitcore node.Before you begin, you'll need to have around 8GB of memory and about 200GB of disk space available to store the Bitcoin blockchain plus additional database information.Both 64bit Mac OS X and GNU/Linux are currently supported.The process of downloading the blocks and indexing can take upwards of 24 hours on livenet and 2 hours for testnet, depending on Internet connection and other factors such as CPU and disk speed.It's also possible to use an existing Bitcoin data directory, which will speed up the process as reindexing can take upwards of 12 hours for livenet and 1 hour for testnet.It's recommended to install the Node Version Manager, as this makes it simple to switch between different Node.js versions./creationix/nvm#install-script and then run: For GNU/Linux distribution such as Debian or Ubuntu: Bitcore comes with a command line utility for creating and managing your full node.To get started, run these commands, and you'll then have the bitcore command in your path: Note: Do not run this command with sudo or with root privileges as this will lead to permission issues.

As mentioned previously, this process can take several hours to complete, so you can start the script and come back later to check on the status.This will start up all of the services that have been enabled in your configuration file.The first service that will most likely be started is Bitcoin itself, followed by others that depend on it, such as the Database and Address Service.bitcoin ne kadarThe syncing process will connect to other Bitcoin peers in the network and start downloading the blockchain, verifying proof-of-work, and creating indexes for querying the blockchain.in bitcoins orbitBoth Bitcoin and the Database Service will log the status of the initial synchronization process.ethereum competitionGet details about the genesis block: Get the details of a transaction (with address information): Note: If you created your node by running bitcored instead of bitcore create mynode, your node will already have these services installed and you can skip this command.
