What is blockchain technology?
Blockchain is a database that stores a constantly growing list of records (blocks). These records are organized in a strict sequence, and each subsequent record stores some information about the previous record. Such a database is stored on users ' computers (it does not have a single server) and everyone who keeps the database has its full copy and new records are added to all existing copies.
The blockchain is there to protect us from fraud within the network, making the transaction very easy and transparent!
Today there are hundreds of blockchains in the world, but today we’ll focus on a few of them:
Bitcoin. Despite being the network that pioneered blockchain, Bitcoin doesn’t feature smart contracts.
Ethereum. Its main goal is to offer more than just another currency, but enable those using it a way to pre-program entire systems of interaction between addresses and tokens, which leads to such things as trustless smart contracts that eliminate the need for intermediaries.
Binance Smart Chain relies on a network of 21 validators, powered by the Proof of Staked Authority (PoSA) consensus algorithm that results in short block times and low fees.
Solana. An open-source blockchain designed for scalable decentralized applications.
Cardano – the first to be founded on peer-reviewed research and developed through evidence-based methods.
