What is Blockchain Technology, and How Does It Work?

Blockchain technology is a decentralized and distributed ledger system that records transactions across multiple computers securely and transparently. Blockchain creates a chain of digital blocks that securely record and link transaction data, ensuring its integrity and transparency through a decentralized network. Blockchain technology was invented by Satoshi Nakamoto in 2009. It was introduced along with Bitcoin to revolutionize the financial sector. Since its invention, blockchain technology has constantly been being developed to solve problems across many industries other than finance. 

What is Blockchain in Simple Words?

Blockchain is like a digital notebook where everyone can write and see each other’s notes, but no one can erase or change what is written. Blockchain is a decentralized ledger, like an account book, that transparently records transactions across different computers. The transactions are recorded in a growing list of blocks, linked together using a cryptographic hash.

How Does Blockchain Work?

Blockchain is a distributed ledger where transactions are stored in a network of computers. Blockchain is similar to a database since it also stores information. The concept of blockchain technology is to create a chain of blocks, each block containing a list of recorded transactions. The blocks are cryptographically linked together in chronological order.

When a transaction is initiated on a blockchain, it is sent to a network of computers, also known as nodes. The node selects a transaction from a pool and tries to verify it by solving a complex mathematical puzzle. This process is known as mining. The miner that solves the puzzle gets the right to add a new block. 

Once the transaction is verified, it is added to the block with other verified transactions. The new block contains the new transaction, solved puzzle, and reference to previous blocks. The blocks are linked together to form a blockchain. The transaction becomes complete when a block is closed.

In a nutshell, here is how blockchain technology works:

  • A new transaction is entered.
  • The transaction is sent to a network of computers known as nodes.
  • Miners try to confirm the validity of a transaction by solving a complex mathematical puzzle.
  • Once the validity is confirmed, the transaction is added to a block containing other verified transactions.
  • The blocks are cryptographically chained together with the previous block, creating a long list of permanent transactions.
  • The transaction becomes complete when the block is closed.
