Ethereum is the leading smart contract platform. It allows developers to build decentralised applications (dApps) and enabled the explosion of DeFi, NFTs, and token issuance. Transitioned from Proof of Work to Proof of Stake in 2022.
Solana is a high-performance Layer 1 blockchain capable of processing up to 65,000 transactions per second using a novel Proof of History consensus mechanism. It has become a major hub for DeFi, NFTs, and consumer crypto applications.
An NFT is a unique digital token stored on a blockchain that proves ownership of a specific digital item — art, music, video, game items, or anything else. Unlike currencies, each NFT is distinct and cannot be directly exchanged 1:1 for another. The NFT boom of 2021 saw billions traded, before a sharp market correction.
Solidity is the primary programming language for writing Ethereum smart contracts. It is a statically-typed, contract-oriented language with syntax influenced by JavaScript and C++. It powers virtually all DeFi protocols, NFT contracts, and DAOs on Ethereum and EVM-compatible chains.
Smart contracts are self-executing programs stored on a blockchain that automatically enforce the terms of an agreement when predefined conditions are met. They are the foundation of DeFi, NFTs, and decentralised autonomous organisations.
Web3 is a vision of a decentralised internet built on blockchain technology, where users own their data and digital assets rather than surrendering them to tech giants. It encompasses cryptocurrencies, NFTs, DAOs, and decentralised applications.
