Blockchain was first described as the distributed ledger underlying Bitcoin transactions in 2008. Since then, the technology has emerged as a unique and independent technical solution, with interest pouring from all directions. Governments, businesses, and other organizations have been investigating and adopting blockchain technology to address various needs since the evolution of blockchain technology. What’s more interesting is that most of these companies have nothing to do with digital money. 

After all, blockchain provides security, immutability, traceability, and transparency across a dispersed network. Blockchain technology, therefore, is highly suited to use cases that are challenging to handle with standard infrastructure.

But was it always that way, or has the evolution of blockchain brought new and better use cases compared to the solutions that this technology first introduced? Le. Lets go ahead and explore all about it below in detail. 

The history and evolution of Blockchain Technology

While blockchain seems like a smart and innovative approach to the modern day, its idea and technology were brought to the world’s attention years back. Many of the tools that blockchain is built on have been around for a long time, long before Bitcoin. The computer scientist Ralph Merkle created the Merkle tree, one of these systems. 

In his PhD thesis for Stanford University in 1979, Merkle discussed a method called “tree authentication” for distributing public keys and digital signatures. He finally got a patent for this idea to sign digital documents. The Merkle tree is a way to organize data that can be used to check each record. But Merkle wasn’t the only person who helped make blockchain possible. In his 1982 PhD dissertation for the University of California, Berkeley, David Chaum wrote about a vault system for groups that don’t trust each other to set up, manage, and trust computer systems. 

This method had many of the same parts that make up a blockchain. People also say that Chaum invented digital cash, and in 1989, he started the DigiCash company. Blockchain is also vastly used in Finance industry. It is the future of banking, loans and insurance.

1. P2P network

Many other things were going on during these early years that also made blockchain possible. For example, this time period saw the rise of the peer-to-peer (P2P) network as many projects and companies adopted P2P on their platforms. Napster, which no longer exists, made this idea well-known in 1999. 

Some would say Napster wasn’t a peer-to-peer network because it had a central computer. Still, the service gave the P2P network new life and made it possible to build a spread system that could use thousands of computers’ computing power and storage space.

2. PoW

During this time, the proof-of-work (PoW) idea was also created to verify the work done on a computer and stop cyberattacks. This made way for hashcash, a Proof-of-Work method that helps protect against denial-of-service attacks. Adam Back came up with hashcash in 1997 to stop spam emails. Then, in 2004, Hal Finney developed reusable PoW to get an RSA-signed token in trade for a non-exchangeable (or non-fungible) hashcash token. The PoW method is a key part of Bitcoin mining.

Later, in 2008, the Bitcoin/blockchain architecture was built on ideas and tools from the past 30 years. In Nakamoto’s creation, there was also the idea of a “chain of blocks.” This made it possible to add blocks without needing a trusted third party to sign them. 

In fact, Nakamoto described an electronic coin as a “chain of digital signatures” where each owner gives the coin to the next owner. His white paper says this is done by “digitally signing a hash of the previous transaction and the public key of the next owner and adding these to the end of the coin.”

3. Bitcoin

But Nakamoto’s white paper wasn’t the end of the story. In 2009, Bitcoin became more than just an idea. When he made it, Nakamoto ensured there would never be more than 21 million bitcoins. 

Already, more than 18 million have been taken out. Based on how fast Bitcoin is being mined, the 21 million caps should be reached around 2140. Even though prices always go up and down, their value keeps increasing. One Bitcoin was worth less than 1 cent in October 2009. Each Bitcoin is worth more than $35,000 (USD) right now. By the time 2013 came around, blockchain evolution led to the establishment of Bitcoin, which to this date, continues to grow and improve. In February, Coinbase said it sold $1 million worth of bitcoins in a single month at more than $22 each. 

By the end of March, there were 11 million Bitcoin in use, and the total value of the currency had gone over $1 billion. The first Bitcoin ATM opened in Vancouver, B.C., in October of that year. But not all of the news about digital cash was good. Thailand and China both made it illegal to use cryptocurrency. The U.S. Federal Court took the money that Mt. Gox had in the U.S. Furthermore, the FBI shut down Silk Road and took 26,000 Bitcoin from it.

Even with these problems, Vitalik Buterin, who helped start Bitcoin Magazine, wrote a white paper that suggested a platform for independent apps. Today, we can see many platforms in all sectors and industries, including BigCommerce, Guess Fashion, Cash App, and even governments like El Salvador; all accepting Bitcoin. In fact, the Bitcoin platform itself has evolved into introducing additional digital asset accessibility to its investor’s community through NFTs. 

4. Ethereum

Because of this, the Ethereum Foundation was started in 2014. Ethereum made it possible to use blockchain technology for more than just coins. It made smart contracts possible and gave developers a place to start building autonomous apps.

2014, again, was a turning point for blockchain evolution. Financial institutions and other industries started to see its promise and look into it, shifting their attention from developing digital currency to developing blockchain technologies.

In 2015, the evolution of blockchain technology led to the Ethereum Frontier network going live. This lets developers write smart contracts and decentralized apps that could be used on a live network. Ethereum was on its way to being one of the most important ways that blockchain technology was used. It brought together a group of busy developers still going strong today.

But there were also other important events that year that contributed to the blockchain evolution, including: 

• NASDAQ started a blockchain test.
• The Hyperledger project began with the help of the Linux Foundation. 
• Nine of the biggest investment banks got together to form the R3 partnership. This group is looking into how blockchain could help their businesses. Moreover, more than 40 financial companies joined the group in just six months.

Later, in 2021, the co-founder of Ethereum released a roadmap explaining the future of Ethereum and how it will introduce better solutions for companies and users. Today, more and more businesses see blockchain as a valuable technology different from Bitcoin and other digital currencies.

5. Web 3.0

As blockchain continues to improve, leading to blockchain evolution in 2023, there’s no denying that this smart technology has come a long way. It has introduced many efficient solutions for governments and businesses to improve their operations, from smart contracts to smart wallets. One of the most revolutionary aspects that the blockchain evolution in 2023 has introduced is Web 3.0. 

But since we’re no longer new to Web 3.0, this innovative internet surfing approach is all set to offer more than it already does. In fact, as blockchain continues to change, Web 3.0 is expected to give brands, and people access to more tools that will let them make their own online spaces and set up digital democracies. With multiple Web 3.0 startups today, the next step in developing the Web will use encryption to keep users’ personal information safer. Also, blockchain technology is used to make sure that deals between users are safe. Because it can make an unchangeable record of deals and activity, the blockchain is a reliable way to check facts. 

What makes Web3 trends so important is that the market can grow and change. The world Web3 market was expected to be worth $3.2 billion in 2021. This industry is projected to grow to $38.6 billion by 2030. 

Along with the introduction of 5G or 6G technology, the rise is expected to be caused by the rapid rise in the use of digital assets. The growth of the Web3 blockchain market is also helped by the rise of connected products and the improvement of transaction processes. This could make Web3 more flexible and interactive, making it possible to reach more people than ever.
