How to Implement Blockchain Technology

Initially associated exclusively with cryptocurrency, today blockchain is transforming diverse industries. Forward-looking businesses operating in fintech, real estate, manufacturing, healthcare, pharmacy, and supply chain management have already adopted this powerful technology to optimize their work processes and solidify security. Many more are considering how to utilize blockchain technology smartly in their niches.

Basics You Need to Know

To put it simply, blockchain is a digital, distributed storage where transactions are recorded across all nodes within a network. It consists of a succession of blocks, each of which is connected with a preceding block via a hash. Due to this setup, once data is inserted into a block, there is no chance to alter it without affecting all succeeding blocks, which makes blockchain extremely secure.

To clearly understand how blockchain functions and maintains its integrity, it is vital to know its main components:

• Transactions. These are data exchanges and asset transfers between blockchain participants.

• Blocks. Blocks can be defined as digital containers that store transactions. Each block is timestamped and connected with a preceding block via cryptographic hashes.

• Chain. A chain is a set of sequentially linked blocks that reflects the whole history of transactions. Blockchain participants can audit it at any time.

• Hash. This is a unique code that serves as an identifier for a particular block. Hashes safeguard against tampering and ensure great data integrity by connecting blocks.

• Nodes. Nodes are devices considered to be blockchain participants. Each of them has an exact copy of blockchain history. Transaction validation is also the responsibility of nodes, due to which decentralization is achieved.

• Smart contracts. These self-running contracts have agreement terms ingrained in the code. They trigger processes and validate agreements without any intermediaries or delays, whenever specified conditions are satisfied.

• Consensus mechanism. This is a special set of rules that outlines how blockchain nodes reach agreement on transaction validity. Proof of Work, Proof of Stake, Proof of Burn, and Proof of Capacity are just a few examples of such consensus mechanisms. The first two are absolute leaders.

The Main Features of Blockchain Technology

Now let’s review the most prominent peculiarities of blockchain that make it so special.

The above-described features form the foundation of blockchain technology, making it a groundbreaking tool for domains where rock-solid security along with trust are of great importance.

Blockchain Evolution

The first theoretical insights on blockchain were gained in 1991 when two pioneers—Stuart Haber and W. Scott Stornetta—introduced a paper on a cryptographically secured chain of blocks aimed at timestamping digital documents to safeguard against tampering. Later, Nick Szabo, Stefan Konst, Hal Finney, and others also contributed a lot to the blockchain concept development.

Yet, the real turning point was in 2008, when Satoshi Nakamoto’s ‘Bitcoin: A Peer-to-Peer Electronic Cash System’ was published. In this white paper, he outlined a digital currency and introduced blockchain as its core technology. One year later, Nakamoto launched Bitcoin, marking the inception of blockchain. Bitcoin quickly gained momentum, and blockchain drew attention as a super powerful and reliable technology for P2P transactions. The next milestone was the launch of Ethereum by Vitaly Buterin in 2013. It was a brand-new blockchain platform built to support dApps and smart contracts. Due to this, blockchain technology went beyond cryptocurrency and its adoption was fostered in diverse industries.

By 2020, blockchain had matured immensely, and many more of its practical applications had been discovered. The advent of NFTs in 2021 brought a new, big wave of attention to blockchain. It revolutionized art, gaming, and entertainment by making owning and trading unique digital assets possible. Meanwhile, Bitcoin and Ethereum gained incredible popularity, further solidifying the influence of blockchain in the banking domain.
