Blockchain Basics: A Guide for Programmers

As programmers and technology professionals, you must have heard on several occasions about the concepts of blockchain, cryptocurrency and the persistent rise of its applications. Apart from the field of finance, the technology is deemed appropriate in a plethora of other domains such as software engineering, game development, web development, mobile app development etc. Without much ado, let us first brush up the basics of blockchain and delve deep into the wide realm of applications it carries for the programming landscape.

What is Blockchain?

Essentially a blockchain is a distributed ledger holding a secure record of data, based on the principles of cryptography. Each member of the network holds a tokenized copy of the ledger, containing a unique private key. All sorts of networks, such as public-private networks, use blockchain to secure the data stored on their system.

What are the benefits of blockchain technology?

The approach to constructing and maintaining a blockchain ledger brings along a myriad of advantages. These include:

• Secure, immutable, and encrypted data
• Decentralized and democratic decision making
• Strong privacy safeguards, preventing data leakage and data breaches
• Ability to rapidly deploy and infrastructure changes
• Decentralization of storage and storage costs

What are the features of blockchain?

At the core, blockchain records data transactions in an immutable, tamper-proof and distributed ledger. This ledger can be used for:

• Tracking and managing property rights
• Conducting secure, private and verifiable digital transactions
• Recording contracts and creating digital assets
• Building and running distributed applications (dApp)
• Using smart contracts for creating high-level programs
• Securing digital identities

How can blockchain be used in programming?

Programmers have the opportunity to play around and build applications over the blockchain platform. You can use it to create a Software-as-a-Service (SaaS) application and/or build large scale applications. Blockchain could also be put to use to release marketing campaigns, earn money through coding, develop web apps, mobile apps, software, and many other programming tools. Additionally, it could also be used to create custom solutions, build personal libraries and sets of codes, and automate certain aspects of the process. Plus the distributed infrastructure and immutable data store offered by blockchain provide an ideal environment for teams to collaborate, develop complex projects and deploy smart contracts.

What tools are available for working with blockchain?

The blockchain ecosystem has a variety of tools which make it much easier to work with. Some of these include:

• Solidity, an Ethereum-based language
• Truffle, a development environment
• Geth, a blockchain client for Ethereum
• Web3, a collection of libraries
• Hyperledger Fabric, a distributed ledger framework
• Hyperledger Sawtooth, a distributed ledger platform

Concluding Note

In the programming world, blockchain adds a dimension of reliability, decentralization, and transparency. It’s importance will continue to grow in various programming fields, like web development, mobile app development, software development, game development, AI, ML, and building custom solutions, and personal libraries. Therefore, if you are a tech enthusiast, this is the right time to start learning Blockchain technology and to make judicious use of it to give a boost to your career opportunities.
