Ethereum

Ethereum is a decentralized, open-source blockchain with smart contract functionality. Ether (ETH) is the native cryptocurrency of the platform.

The Ethereum network is one of the most popular platforms for building dApps and blockchain solutions. A series of upgrades are currently taking place as part of the transition from Proof-of-Work to a Proof-of-Stake consensus model. This shift allows network participants to stake ETH and earn rewards for supporting the network.

To connect to an Ethereum node, every Ethereum Client e.g. Geth or Erigon implements a JSON-RPC specification. The Ethereum JSON-RPC Specification is a collection of methods that all clients implement.
