Electroneum (ETN) is a Layer 1 blockchain project founded in 2017 by British entrepreneur Richard Ells. Originally developed around mobile cryptocurrency accessibility and everyday digital payments, Electroneum has evolved into an EVM-compatible smart contract network supporting developers, decentralised applications and on-chain transactions.
The project began with a CryptoNote-derived blockchain and became known for its mobile-focused cryptocurrency ecosystem. Its development later included Proof of Responsibility validation before a major transition to the Electroneum Smart Chain in March 2024.
The current network uses a modified Istanbul Byzantine Fault Tolerance (IBFT) consensus mechanism with an authorised validator set. It targets approximately five-second block production and single-block finality, offering predictable transaction confirmation and low network fees.
Electroneum Smart Chain supports Ethereum-compatible tools and smart contracts, enabling developers to build applications using familiar EVM infrastructure. ETN is the network's native cryptocurrency and is used to pay transaction fees and support blockchain operations.
With a history extending back to 2017, Electroneum combines an established cryptocurrency community with a modern Layer 1 infrastructure strategy focused on practical blockchain applications, developer accessibility and energy-efficient network operation.
