Navigating the world of cryptocurrency can be overwhelming, especially for newcomers. Familiarity with key terms can make the experience more understandable and accessible. Below is a comprehensive glossary of essential cryptocurrency terms that will help you grasp the concepts better.
1. Altcoin
Refers to any cryptocurrency other than Bitcoin. Notable altcoins include Ethereum, Ripple, and Litecoin. Altcoins offer various features and use cases, which often aim to improve upon Bitcoin’s technology.
2. Blockchain
A decentralized, distributed ledger technology that records all transactions across a network. Each block contains a number of transactions, and once confirmed, they are added in chronological order.
3. Address
A unique string of characters used to receive cryptocurrency. Similar to a bank account number, it enables users to send and receive funds securely.
