Blockchain is one of the most talked-about technologies in the world. It’s been heralded as a revolutionary way to share data, create trust between parties, and even change the way we do business. But where did blockchain come from? How long has it been around? Let’s take a look at the brief history of blockchain:

The history of blockchain technology

Blockchain. This a word you hear more and more these days, but do you know where it comes from? Blockchain technology has been around since the early days of the internet, originating with its namesake: Satoshi Nakamoto in 2008. The phrase “blockchain” was first used to describe a decentralized ledger system that allowed payments on top of Bitcoin. While Bitcoin is still one of the most popular uses for blockchain technology today, it also allows many other types of transactions to take place on a decentralized network.

How Did Blockchain Start?

The first blockchain was created by Satoshi Nakamoto, the pseudonymous creator of Bitcoin. A blockchain is a decentralized digital ledger that records transactions between two parties efficiently and in a verifiable and permanent way. Bitcoin was the first cryptocurrency to use blockchain technology, but other crypto-assets have been created since then with both public and private blockchains.

What is the Purpose of Blockchain Technology?

The original purpose of blockchain technology was to create a shared, decentralized ledger. This means that instead of having one centralized authority keep track of transactions and other information, it would be stored across multiple computers. The result is a distributed database that no one party controls—in fact, it’s completely decentralized.

Blockchain can be used to record any kind of transaction or movement—from money to goods to even votes in elections! It works by creating digital “blocks” made up of information about the transaction being made (like the amount or type) along with a time stamp and then attaching this block to a chain of previous blocks created by previous transactions. This means that if you go back far enough on this chain, you can see all past history since its creation so long as everyone keeps adding new ones.

How Secure Is the Blockchain Technology?

Blockchain is considered to be the most secure technology that exists today. It is a distributed ledger of transactions, which means that each block in a chain contains many transactions, and these blocks are linked together to form a chain.

When you make a transaction using blockchain technology, it gets verified by multiple nodes before being added to an existing block on the chain. This makes it almost impossible for hackers or fraudsters to break into your account because they won’t be able to access all of your information at once (and if they did manage to get hold of some data, it would still be encrypted).

Blockchain also has three other key characteristics: immutability (meaning nothing can change it), transparency (anyone can view what is happening) and decentralization (no single entity controls how things are done).

Real-World Applications of Blockchain Technology

The following examples span various industries and applications.

  • Financial Services

Blockchains provide tamper-proof record keeping, which can help improve the customer experience by reducing the time it takes to process transactions and provide accurate information for clients. For example, blockchain technology has been used to replace centralised paper ledgers with decentralized ones in trade finance; this allows companies to track goods as they move from supplier to buyer, improving transparency and reducing fraud along the way (McKinsey & Company).

  • Supply Chain Management

Blockchain technology can streamline supply chain management by providing real-time visibility into items being tracked through a system of decentralized nodes (Nasdaq). This reduces error rates while also making it easier for companies to trace products back through their supply chains if there are issues with quality control down the line (IBM).
