Acurast Architecture

Acurast’s three-layered architecture — Consensus, Zero Trust Execution, and Application — provides a modular, decentralized platform ensuring privacy, verifiability, and interoperability. By separating layers, Acurast addresses trust centralization, allowing native settlements across ecosystems.

Acurast architecture

The Consensus Layer incorporates an Orchestrator and reputation engine to match jobs with processors securely.

The Zero Trust Execution Layer, with runtimes like Acurast Secure Hardware Runtime (ASHR) and Zero-Knowledge Runtime (AZKR), ensures confidential computation.

The Application Layer hosts Web2 or Web3 applications, revolutionizing decentralized use cases.

Built on Polkadot SDK/Substrate Runtime, Acurast leverages Parachain slots on Kusama and Polkadot, ensuring security and cross-consensus communication. The architecture enables developers to define, deploy, and fulfill Zero Trust jobs seamlessly, advancing decentralized application development.

Consumers, Processors and Orchestrators

Consumers, seeking confidential, verifiable, and efficient computation, can declare jobs, register them, and define parameters through Acurast Orchestrator, connecting with Processors for execution and rewarding them for their computing resources.

Acurast Processors offer computational capacity to Consumers, utilizing Android smartphones as off-chain infrastructure. Processors, following user-specified instructions, fulfill jobs, providing verifiable output, and Proof of Execution.

The Acurast Orchestrator, a consensus layer centerpiece, orchestrates Processor and Consumer interactions, facilitating liquid matching of computational resources. It supports various price-finding mechanisms, ensuring seamless agreement and value exchange between Processors and Consumers in a secure, interoperable environment.

What is a Zero Trust Application?

Zero trust applications are like computer tasks that follow specific instructions without needing trust in others. Developers use JavaScript to program their applications and can deploy them easily on Acurast, to be run in the Acurast Secure Hardware Runtime (ASHR). Think of them like Ethereum Smart Contracts but with added benefits like versatility, confidentiality, and scalability. Unlike Ethereum, Zero Trust applications offer more flexibility, security, and most importantly more computational performance for developers. You can deploy entire interactive JavaScript backends on Acurast.

Security Features

Acurast provides a zero-trust approach, addressing the widely recognized challenges of blockchains and the Internet: Scalable confidential compute without a centralized party. Its design enables a permissionless and universally interoperable zero-trust future. Acurast is a platform and protocol that orchestrates and schedules the participants’ intentions and executes these in a confidential computing context. It provides developers with a distributed, highly scalable arbitrary computation engine ready to be used for the most security-sensitive tasks.

Upcycle your Android Smartphone and join as Processor (Reward Program is On)

The Acurast team identified early on that the true decentralized compute platform is not server hardware located in centralized data centers, but are smartphones. It is not known to many, but Smartphone Operating Systems (iOS, Android) offers a superior security design compared to server and workspace Operating Systems (Linux, MacOS, Windows, …). What is unintuitive becomes clear when looking at how the devices are used: servers don’t need to protect from physical attack vectors, while mobile devices by design don’t have that privilege, they can be forgotten in public places, stolen, etc. For this reason, also the hardware security modules in mobile devices offer superior security features compared to server hardware. Another great reason why smartphone hardware is a perfect candidate for decentralized compute is the low running cost thanks to the powerful yet highly efficient hardware.

As developers and Acurast Consumers pay you for the provided computation, becoming an Acurast processor is an easy way to monetize that spare smartphone you have lying around. To onboard is very easy, you don’t need to be a Linux geek. All you have to do is grab a spare Android device, factory reset it and scan a QR. Within 3 minutes you are up and running earning cACU tokens on the Acurast canary net. Head over to to get started.

On top of the rewards paid for the compute the Acurast protocol is further incentivizing the onboarding of processors with its “Processor Bootstrap Program”, where per month and running device every processor is paid 250 cACU per month. Rumors say it may be used to determine eligibility for the Airdrop campaign of the mainnet token ACU set to launch later this year.

The Road to Acurast Mainnet

In a recent update, Acurast Association sheds light on its multi-faceted approach to supporting protocols. Acurast operates in three distinct networks:

  • Testnet for experimentation,
  • Canary for production-grade applications,
  • Mainnet for long-term use.

The Acurast Testnet is already live, with a connection to the Rococo relay network. Acurast Canary has launched in phases, starting on Programmer’s Day, September 13th, 2023.

Developers are invited to engage, test Acurast, and explore its Canary network, marking the path toward the anticipated Acurast Mainnet. Acurast promises a transformative journey for developers and processors alike.

Alpha-Net, scheduled for later this year, aims to incorporate external Collators and initiate a Proof of Stake mechanism for their selection, resembling Curve’s voted escrow model, with block production rewards distributed through Acurast’s adaptive inflation model.

Following Alpha-Net, the Beta-Net, expected two months later, eliminates sudo, transferring governance to active stakers and enabling token transfers, marking a crucial step as Acurast Canary paves the way for the forthcoming Acurast Mainnet launch.
