Ethereum RPC
이더리움이란 무엇인가요?
Ethereum is the most widely adopted smart contract blockchain, powered by the Ethereum Virtual Machine (EVM). Developers write smart contracts primarily in Solidity (or other EVM-compatible languages like Vyper, Yul), which compile to EVM bytecode and deploy across Ethereum's decentralized network of validator and full nodes.
Since 2022, Ethereum uses a proof-of-stake (PoS) consensus mechanism and maintains an account-based model to track balances and smart contract state. Together, these features make Ethereum a secure, programmable foundation for decentralized applications (dApps).
What is the Ethereum JSON-RPC API?
Ethereum nodes expose a JSON-RPC interface that allows developers to interact with the blockchain programmatically. This is known as the Ethereum JSON-RPC API.
이 API를 사용하면 다음과 같은 작업을 수행할 수 있습니다:
- Query blockchain state (blocks, transactions, receipts, logs)
- Send transactions
- Deploy and interact with smart contracts
- Subscribe to real-time events (via WebSocket subscriptions such as eth_subscribe)
다음과 같은 방법으로 API에 접속할 수 있습니다:
- Running a local Ethereum client (e.g., Geth, Nethermind, Besu). You can learn how by looking at our node setup guides here.
- Using a hosted provider such as a Quicknode Ethereum endpoint, which delivers low-latency global access, archive data, and enhanced reliability out of the box.
