System architecture

The architecture of Arthera has three major components:

Arthera Blockchain

An open cryptographic protocol that allows applications to make transactions with and run smart contracts in a secure and decentralized way. The Arthera blockchain has a lot in common with Ethereum and maintains full EVM compatibility for smart contracts. However, it uses an Asynchronous DAG-based Byzantine Fault Tolerant (BFT) consensus mechanism (Proof-of-Stake) and has different block format, transaction format, client synchronization protocols, and gas payment and pricing mechanisms.

Core System Contracts

A set of smart contracts running on the Arthera blockchain that include much of the logic of the platform features including subscriptions, identities, proof-of-stake, and governance. These Core System Contracts are upgradeable and managed by a decentralized governance process.


Applications or DApps built on Arthera either by Arthera itself or by developers using the available Arthera SDKs. A number of pre-built applications needed to operate the network are available or currently in construction:

  • Arthera Wallet - a mobile-compatible web application where users manage their account on the Arthera network
  • Arthera Explorer - the official blockchain explorer
  • Arthera Launchpad - a service platform for startups where
  • Arthera Store - store for DApps and subscriptions
  • Arthera Connect - a place where ecosystem builders meet, discuss, exchange ideas and partner
  • Arthera Governance - where protocol decisions are made through a decentralized governance model


Validators gather and execute transactions received from other nodes along with smart contract code to form new blocks, then participate in the Asynchronous Byzantine Fault Tolerant (BFT) consensus protocol to advance the state of the network.
