A blockchain is a decentralized, distributed public ledger that operates on the internet. It’s a digital database that records data, and no one can change or corrupt the information stored therein. Three principal technologies define the operation of a blockchain:
- Private key cryptography: A secure code that allows crypto holders to make transactions and prove ownership of their assets;
- Distributed network: A shared ledger that regulates data and transactions to avoid fraud and tax evasion;
- Reward or incentive: A token is given to miners for servicing the blockchain and maintaining its security levels. A blockchain can be public, private, permission-based, centralized, or decentralized. Each blockchain has a team, usually consisting of multiple parties that use cryptography to ensure all transactions are secure, accessible, consistent, and tamper-proof. Crypto beginners’ corner:
