Ethereum (execution layer)
Ethereum is a decentralized, open-source blockchain network with Turing-complete smart contract functionality. Ether (ETH) is the native cryptocurrency.
Users manage the global state of the Ethereum (execution layer) with a decentralized proof-of-work (PoW) consensus mechanism. The ETH2 (consensus layer) replaces PoW with a proof-of-stake (PoS) consensus mechanism.
The Ethereum JSON-RPC API is a library of methods that interact with the Ethereum blockchain via JSON-RPC. Methods include functionality for reading and writing data to the network, and executing smart contracts.
Use the Ethereum JSON-RPC API on:
  • Ethereum Mainnet.
  • Ethereum testnets Rinkeby, Kovan, Görli, and Ropsten.
  • Polygon.
  • Optimism.
  • Arbitrum.
