One of the most popular phrases so far this year is “Web 3,” which is based on the same blockchain technology that underpins cryptocurrencies. This piece will make an effort to demystify blockchain technology, explain how it operates, go over tokens and ledgers, and generally help us grasp this crucial technology better.
A blockchain can be thought of as a digital ledger of transactions that is duplicated and dispersed throughout a sizable network of computers that are a part of the blockchain. This is a straightforward explanation to start with. Each “block” on the blockchain is made up of a number of transactions, and each time a new transaction takes place, a record of it is added to the blockchain ledger of each participant. The blockchain is protected from fraud and theft since no single party has control over it, making it difficult to hack and impossible to fabricate transactions.
The History of Blockchain Technology
In his 1982 paper “Computer Systems Established, Maintained, and Trusted by Mutually Suspicious Groups,” cryptographer David Chaum first suggested a blockchain-like protocol, but the first decentralised blockchain was actually imagined in 2008 by a person or group of people going by the name Satoshi Nakamoto.
By timestamping blocks similarly to Hashcash without requiring the blockchains to be signed by a third party, Nakamoto improved the blockchain development concept. Additionally, he added a parameter for difficulty that controls how quickly blocks are added to the chain. As a key element of the Bitcoin cryptocurrency, Nakamoto put the plan into practice in 2009.
The size of the Bitcoin blockchain file, which contains a history of all transactions, reached 20 GB in August 2014. The size of the ledger had surpassed 200 GB by the beginning of 2020, and by January 2022, it had surpassed 374 GB.
The Blockchain Ledger: What Is It?
The blockchain ledger’s operation is superbly explained by Blockgeeks. It’s simple to grasp thanks to their comparison, “Consider a spreadsheet that has been replicated thousands of times across a computer network. Next, suppose that this network is made to automatically update this spreadsheet, and you have a fundamental knowledge of the blockchain. Each transaction that is listed on the ledger is kept in a unit called a “block,” and each block contains a number of transactions. The information in each block is related to and dependent upon the information in the block before it. These blocks eventually come together to form a “chain” of transactions, or “blockchain.”
What is the concept of Decentralization?
The advantages of a decentralised network are many, but nobody needs to know or trust anyone else because they don’t have to go through a “trusted party.” Each member of the network has a copy of the distributed ledger, which is made up entirely of the same information. The other network participants will reject a person’s altered or corrupted ledger.
One drawback of a decentralised network is that it tends to operate more slowly the larger it becomes. Contrary to distributed systems, security comes first in decentralised blockchain systems. Performance declines as a blockchain network grows or expands, even while the network’s security increases. This is due to the requirement that each member node validate each piece of information before it is added to the ledger.
Blockchain is frequently mentioned in relation to money or banking, but there are many more uses for it than that.
“Prior to the development of the World Wide Web, the majority of websites were managed by individuals or organizations that hosted their own systems and data. Later, Web 1.0 would be the name given to this format. We transitioned into Web 2.0 when community services, social networking, and hosting services (Google Cloud, Azure, AWS) became the main framework of the internet. In a conceptual sense, this changed the web from a collection of disparate endpoints to a sizable body of aggregated data controlled by a small number of businesses. The concept behind Web 3.0 is to move the web to where its biggest contributors are: individual users on mobile phones or other Internet of Things (IoT) devices.

Risks of Decentralization
Web3 technology, such as blockchain, has the potential to change the Web, but it is not without risks, according to Ryan Spanier, vice president of innovation at Kudelski Security. “Decentralization enables people to manage their own finances, digital assets, and privacy and security. The advantages to people are substantial. However, this also creates fresh threats that are always changing. The concept of a fully decentralised ecosystem is unfeasible until people have the efficient tools and knowledge required to combat these threats independently. On top of Web3, however, centralised operations with security safeguards and enforcement techniques will continue to flourish because they give users the safety and security they need to have faith in the system, according to Spanier.
The blockchain is simply an extremely efficient and effective technique of transparently storing and distributing data without the need for a trusted source, using a decentralised distribution mechanism, despite the fact that it can be difficult to explain.
