Chapter 2: How Does Cryptocurrency Work?
In this chapter, we will delve into the underlying mechanisms and processes that enable the functioning of cryptocurrencies. Understanding how cryptocurrency works is essential for grasping its potential and harnessing its benefits effectively.
2.1 Distributed Ledger Technology
At the heart of cryptocurrency is a technology called distributed ledger, commonly known as blockchain. A blockchain is a decentralized and transparent ledger that records all transactions across a network of computers. Each transaction is grouped into a block, which is then added to the chain in a sequential and immutable manner. This ensures transparency, security, and integrity in the transaction history.
2.2 Cryptocurrency Mining
Cryptocurrency mining is the process by which new cryptocurrency units are created and transactions are verified. Miners use powerful computers to solve complex mathematical problems, known as proof-of-work, to validate transactions and add them to the blockchain. Miners are rewarded with newly minted cryptocurrency units as an incentive for their computational efforts.
2.3 Wallets and Addresses
Cryptocurrency wallets are digital storage solutions that allow users to securely store their cryptocurrency holdings. Wallets come in various forms, including software wallets, hardware wallets, and online wallets. Each wallet has a unique address, which serves as the destination for sending and receiving cryptocurrency.
2.4 Public and Private Keys
Public and private keys are cryptographic keys used in cryptocurrency transactions. The public key acts as an address to which others can send cryptocurrency, while the private key is kept secret and is used to sign transactions for authentication. The combination of these keys ensures the security and privacy of cryptocurrency transactions.
2.5 Transaction Verification
Every transaction in a cryptocurrency network must be verified to ensure its validity. This verification process involves confirming the transaction details, checking the digital signatures, and ensuring that the sender has sufficient funds. Once verified, the transaction is added to the blockchain, making it a permanent and unalterable record.
2.6 Consensus Mechanisms
Consensus mechanisms are protocols that enable agreement and validation of transactions in a decentralized network. Popular consensus mechanisms include Proof-of-Work (PoW) and Proof-of-Stake (PoS). PoW requires miners to solve complex mathematical puzzles, while PoS allows participants to validate transactions based on the number of coins they hold.
