Welcome to the section on Blockchain Basics. Here, you will find an overview of what blockchain technology is, its components, and its significance in the modern world.
What is Blockchain?
Blockchain is a decentralized digital ledger that records transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network.
- Decentralization: Unlike traditional ledgers, which are maintained by a central authority, blockchain is maintained by a network of computers.
- Transparency: All transactions are visible to everyone in the network.
- Immutability: Once recorded, the data in any given block cannot be altered without altering all subsequent blocks, which requires network consensus.
Key Components of Blockchain
- Blocks: These are the individual records that make up the blockchain. Each block contains a list of transactions, a timestamp, and a unique code called a hash.
- Chains: The blocks are linked together in a chain, forming a chronological record of transactions.
- Miners: These are the individuals or groups that validate and add new blocks to the blockchain. They are rewarded with cryptocurrency for their work.
Significance of Blockchain
- Financial Inclusion: Blockchain can provide financial services to unbanked or underbanked populations.
- Security: The decentralized nature of blockchain makes it very secure against hacking and fraud.
- Efficiency: Blockchain can streamline transactions and reduce costs.
