The Evolution of Blockchain

The Evolution of Blockchain

Bitcoin and the first blockchain innovation came into existence for over a decade. They were created with the idea of providing an easier platform to transfer value between two parties, without the need of a third-party. Blockchain has been a revolutionary innovation ever since its inception widely used across multiple industries.

Throughout the last decade, it has been developed further and has been applied in various applications and products. It is independent of country borders and national currencies. This is the reason why it is seen as the greatest innovation since the Internet.

Over the years, new blockchain applications have grown over industries. Bitcoin is one of the first beneficiaries of the blockchain revolution before the emergence of second and third generation blockchain platforms. In this article, we will explore all three generations of blockchain.


1st Generation – Cryptocurrencies

The first major blockchain application was Bitcoin, the most renowned digital currency. For the first time, it was possible to transfer money without any third-party intervention. Each bitcoin transfers the complete ownership and record of transactions. This type of money is termed as a cryptocurrency. The founder of Bitcoin, Satoshi Nakamoto, made the code behind Bitcoin an open source, gaving everyone the opportunity to learn, build and expand beyond it. 

2nd Generation – Assets

The second generation of Blockchain includes the likes of Ethereum, NEO and QTUM which help in recording transactions that happen over a blockchain network and also expands it to involve programming language.

As the bitcoin became a hype in the tech world, it brought in new ideas to apply the blockchain ledger to broader use cases, by offering the administration of assets. Individuals were allowed to issue shares on Blockchain. The shares could receive dividends and the shareowners could also get the voting rights. This idea facilitated the idea of crowd ownership that fits well in the generation that promotes crowdfunding and sharing economy.

3rd Generation – Smart Contracts, Proof of Stake and Blockchain Scaling

Blockchain also had the capability to register agreements. Smart Contracts are basically computer programs that are fed into the blockchain network which allowed financial instruments like loans or bonds to be also represented instead of only cash-like tokens like the bitcoin. A smart contract enforces the participant to keep their promise. For example, imagine an insurance contract that requires payments at regular intervals. If the payee fails to make the payment, the contract ends. Smart Contracts are a very useful technology to automate processes in the future.

There were blockchain networks that were secured by ‘proof of work’ where the group, called miners, with the largest total computing power gets the right of making the decisions. These miners operate data centers to provide security for the cryptocurrency payments. The proof of stake concept states that a person can mine and validate a transaction depending upon the number of coins he holds in his wallet. The higher the bitcoin, the higher the power to control the transaction.

It was the third generation where the idea of blockchain scaling came into place. Currently, every computer in the network processes every transaction making the system slow. A scaled blockchain accelerates the process by analyzing how many computers are actually important to process the transaction, without compromising on the security and robustness of the system.

What’s Next?

New concepts such as Soferox – Proof of Pact have emerged to reap maximum benefits out of this technology. There is also Graphene that helps the processing done by nodes in a more effective activity. As the network continues to grow, it will be interesting to look at the new ideas that will lead the way to a faster and more reliable transactional environment.

    Bitcoin wasn't mainstream until 2014. People were also unaware of the existence of blockchain until crypto currencies became widely used. I am still skeptical about them but do think that blockchain, the main innovation behind them, is here to stay. Blockchain will change many sectors for the better.

    Vitalik Buterin is trully a prodigy. Ethereum extended the concept of Bitcoin beyond just currency.

  • Ben Walker

    Perhaps the 4th generation of blockchain could come with more regulation and acceptance by the global governments.

  • Claudia Warburton

    Blockchain isn't that secure, people can stil hack some platforms.........

  • Theo Hadley

    Microsoft wants to launch a cloud version of Blockchain on a permission-ed playground.

  • Greg Calladine

    The rate at which the Blockchain technology is evolving the Gen Z and Gen Aplha might not hear about most of the blockchain platforms.
