• Cryptocurrency is a decentralised digital currency that is secured by cryptography and is based on blockchain technology. To comprehend bitcoin, one must first grasp three concepts: blockchain, decentralisation, and cryptography.
• In the context of cryptocurrencies, blockchain is a digital ledger whose access is dispersed among authorised users. This ledger keeps track of transactions involving a variety of assets, including money, real estate, and even intellectual property.
• Users share access, and any information sent is clear, instantaneous, and 'immutable.' Anything recorded on the blockchain is immutable, meaning it cannot be changed or tampered with - even by the administrator.
• Mining, which is employed by Bitcoin, is one of the most popular ways cryptocurrencies are created. Mining is a time-consuming process in which computers solve complicated riddles in order to validate the validity of network transactions. The owners of those computers may earn newly minted cryptocurrency as a reward. Other cryptocurrencies manufacture and distribute tokens in different ways, and several have a substantially lower environmental impact.
