Blockchain is a decentralized, digital ledger that records transactions in a secure and transparent manner.
It allows for the creation of a tamper-proof and publicly accessible database that can be used for a variety of applications, including financial transactions, supply chain management, and voting systems.
At its core, a blockchain is a series of blocks that contain data.
Each block contains a unique code, known as a hash, that links it to the previous block in the chain.
This creates an unbreakable chain of blocks, with each block containing a record of transactions that have occurred.
When a new transaction is made on a blockchain, it is verified by a network of computers known as nodes.
These nodes check the transaction to ensure that it is valid and then add it to a new block, along with other validated transactions.
Once the new block is created, it is added to the existing chain of blocks, creating a new link in the chain.
This process is repeated for each new transaction that is added to the blockchain, creating a continuously growing chain of validated and secure transactions.
Because the blockchain is decentralized and distributed across a network of computers, it is extremely difficult for any one individual or group to manipulate the data stored on the blockchain.
This makes the blockchain an ideal solution for any application that requires a secure, transparent, and decentralized ledger.
