Before you begin investing in crypto, you should probably understand how it works. Read this! Even your grandma could understand it!
A blockchain is a decentralized digital ledger that records transactions across multiple computers securely and transparently. These traits make it very resistant to tampering. It is a foundational technology behind digital currencies like Bitcoin, but blockchains extend beyond crypto applications.
The embedded consensus mechanism prioritizes security, which makes it an attractive solution for industries looking to enhance transparency, reduce fraud, and streamline processes.
Blockchain also works in other sectors, such as supply chain management, healthcare, finance, and smart contracts.
Traditional systems are usually centralized. A single authority controls all the data. Blockchains are decentralized. They operate on a network of computers (nodes), and each node has a copy of the entire blockchain. This continual procedure creates countless checks and balances on each new data entry, increasing the difficulty for mistakes to occur.
Data distributes in the form of blocks across all nodes in the network. Each block contains a list of transactions, a timestamp, and a reference to the previous block. These blocks build on top of each other, creating the blockchain.
To add a new block to the blockchain, nodes in the network must reach a consensus. In other words, they must agree by a majority that the incoming data is valid. Various consensus mechanisms, such as Proof of Work or Proof of Stake, ensure agreement among nodes on the validity of transactions and the order of blocks.
Once a block is added to the chain, altering the information in a single block requires changing all subsequent blocks, which is practically impossible. Changing a…
