Cryptography
Security and trust in Ethereum are underpinned by advanced cryptographic techniques. Transactions are secured using public key cryptography, ensuring that only the rightful owner can authorize transfers through digital signatures. Additionally, cryptographic hashing guarantees data integrity and links transactions securely across blocks, making the blockchain resistant to tampering.
Smart Contracts
A pivotal feature that differentiates Ethereum is its support for smart contracts. These are self-executing agreements written in code, which automatically trigger actions once predefined conditions are met. This innovation eliminates the need for intermediaries, reduces costs, and increases transparency. Developers use programming languages like Solidity to develop these contracts, unleashing a spectrum of decentralized applications across various sectors.
Applied Aspects of Ethereum
