Ethereumjärjestelmiin

Ethereumjärjestelmiin refers to the various systems and components that make up the Ethereum blockchain. At its core, Ethereum is a decentralized, open-source blockchain system that features smart contract functionality. This means it can execute code automatically when certain conditions are met, enabling a wide range of applications beyond simple cryptocurrency transactions.

The primary components of an Ethereumjärjestelmä include the nodes, which are computers that run the Ethereum software and maintain a copy of the blockchain. These nodes validate transactions and blocks, ensuring the integrity of the network. The blockchain itself is a distributed, immutable ledger that records all transactions and smart contract interactions.

Smart contracts are a crucial element, written in programming languages like Solidity and deployed on the Ethereum blockchain. They automate agreements and processes, forming the basis for decentralized applications (dApps). The Ethereum Virtual Machine (EVM) is the runtime environment for smart contracts, executing their code across all nodes.

The consensus mechanism, historically Proof-of-Work and now primarily Proof-of-Stake, is how nodes agree on the validity of transactions and the state of the blockchain. This system is designed to be secure and resistant to manipulation. Finally, the Ether (ETH) cryptocurrency is native to the Ethereum network, used for transaction fees (gas) and as a store of value.
