Advantages of Bitcoind over BitcoinJ

Posted By : Pawan Kumar Tiwari | 31-Jan-2018

Bitcoin is the technology of this era and everyone is trying to know about it more and more. Bitcoin is the cryptocurrency technology that allows its user to use it virtually. This might be a general description for any general person but as a developer, we daily face various challenges with this current technology.

When we work on any custom bitcoin-related project, we use other libraries for various purposes like transaction, wallet address, hash etc. There are various libraries available for the same task bitcoinJ and bitcoind are one of them. 

You can check the details of bitcoinJ and bitcoind RPC-CLIENT here.

Features of BitcoinJ:

  • Highly optimized lightweight simplified payment verification
  • provides both async and thread-per-connection for network IO
  • Experimental full verification mode which does the same as bitcoin core
  • Support for micropayment channels
  • When the numbers of users increase it lacks the feature of scalability.

Features of Bitcoind RPC-Client:

It is far useful rather than the BitcoinJ, it resolves the main issues that Bitcoinj has.

  • Easy to set up and use in  the project
  • Resolves the scalability issue
  • More secure than Bitcoind
  • It has more flexible inbuilt methods that help us to use it, instead of building a custom one. 
  • It needs authentication before starting and require Bitcoin.conf file.

We need to provide the authentication for Bitcoind when the server starts. For an example -

final String rpcuser ="...";
  final String rpcpassword ="...";
  Authenticator.setDefault(new Authenticator() {
      protected PasswordAuthentication getPasswordAuthentication() {
          return new PasswordAuthentication (rpcuser, rpcpassword.toCharArray());

However,  you can view the example of Bitcoin.conf file on github

When you will install the Bitcoind RPC-Client on your system, you will see the .bitcoin  folder in your system. In that folder you will see bitcoin.conf , this is the file to write the configuration for the Bitcoind. In the same folder, you will wallet.dat file. This file keep your default bitcoind address. 

Here is the Example of Bitcoin.conf 

walletnotify=file path for

I hope, this will help you to get start with bitcoind RPC-Client. If you have any queries, plese drop a comment.
