Blockchain Fundamentals
Blockchain is a decentralized ledger technology. It records transactions across many computers. This setup ensures that the registered transactions cannot be changed retroactively. Each transaction added to a blockchain is called a "block." These blocks form a "chain" as they link together in sequence.
In a blockchain, each participant has access to the entire ledger. This transparency guarantees that the information is consistent and secure. The use of cryptography in blockchain ensures data integrity and security. Smart contracts are digital agreements that automatically execute when conditions are met, further enhancing functionality.
Types of Cryptocurrencies
Cryptocurrencies include a wide range of digital coins, each serving different purposes. The most well-known is Bitcoin, often called "digital gold." It is used primarily as a store of value. On the other hand, Ethereum supports smart contracts and decentralized applications (dApps).
There are also altcoins, which are any cryptocurrencies other than Bitcoin. Examples are Litecoin, Ripple, and Cardano. Each has unique features like faster transaction times or different consensus mechanisms. Stablecoins are another category, typically pegged to a stable asset like the U.S. dollar to reduce volatility.
Decentralisation Explained
Decentralization is the distribution of power and control from a central authority to many smaller entities. In cryptocurrencies, transactions are verified by a network of nodes rather than a single entity. This model enhances security and makes the system more resistant to fraud and censorship.
Decentralized networks eliminate single points of failure, reducing the risk of large-scale hacks. Unlike traditional banking systems, participants in the crypto network maintain control over their funds. This structure fosters transparency and trust among users, which is essential for the widespread adoption of cryptocurrencies.
