Confidential computing

Compute on data in a fully confidential state

With Arcium, computations are executed confidentially, so your data is never exposed to us or to anyone else. Powered by the most advanced cryptography, Arcium leverages Secure Multi-Party Computation (MPC) running across a decentralized network.

How it works

The cloud has to see your data. Arcium doesn't.

A normal server has to open your data to process it. Arcium never does. Inputs are split into secret shares across independent nodes that compute together using MPC, returning a verifiable result. No single node sees your data. Confidential by design.

Arcium Blackthorn

Something is almost here. Years in the making, and built to do what everyone said was impossible, the fastest, most secure way to unlock what the world keeps locked away. We're not ready to show you yet. But when we are, nothing will look the same.

Arcium enables a new wave of 0-to-1 applications. Sealed-bid auctions, the gold standard in TradFi, were never possible on-chain. With Arcium, we calculate a uniform clearing price on fully encoded bids, with an interface as simple as writing an Anchor program.

Recent research

We're pushing the frontier of applied cryptography. The breakthroughs that make confidential AI and computing practical at scale start here, in our research.

$ARX Token

$ARX is the token that serves the Arcium network and its contributors. Real demand for confidential computation becomes real demand for ARX, and the people who secure and run the network are the ones who earn from it.

View full tokenomics

Usage-based fees apply to on- and off-chain transactions that use Arcium or C-SPL. All network growth accrues to $ARX.

Holders delegate $ARX to MPC nodes to secure the network. Rewards are distributed in proportion to each node's performance; underperforming nodes lose delegation over time.

Confidential computations are scheduled through stake-weighted selection. The more $ARX delegated to a node, the more often it is chosen to schedule work, incentivizing nodes to optimize throughput.

$ARX holders govern Arcium on-chain. Voting power scales with lockup duration, and technical proposals require a refundable $ARX fee, burned if the vote fails, to filter out noise.

$ARX isn't live yet. Be the first to know when it launches.

Security model

Security you can verify, not just trust

Every computation runs across a decentralized cluster under maliciously secure MPC. No single node, operator, or insider can read your data or tamper with a result, and every output is verifiable on-chain. The guarantees come from cryptography, not promises.

Build what couldn't be built before.

Join our global community of developers running hundreds of thousands of confidential computations every single day on Arcium.

FAQ

Frequently asked questions

Arcium is a parallelized confidential computing network. It provides developers and applications with a trustless, verifiable, and efficient framework to run encoded computations, bringing confidentiality to every on-chain application and becoming the global computing network for the decentralized internet.
Multiparty computation eXecution Environments (MXEs) are the backbone of the Arcium Network. They combine Multiparty Computation (MPC), Fully Homomorphic Encoding (FHE), Zero-Knowledge Proofs (ZKPs), and more to enable encoded computations. MXEs are highly configurable, letting users customize everything from the trust assumptions to hardware investment.
No. Arcium requires a data availability and state consensus layer, and is thus invoked by an underlying blockchain. This brings better composability and no liquidity fragmentation. Arcium is also designed to be chain-agnostic, so developers can deploy confidential smart contracts across different blockchains.
Arcium provides an SDK for developers to create custom MXE instances tailored to their needs, whether for complex DeFi computations, statistical analysis, or anything in between, plus an API with a web-based interface for constructing computational workflows from predefined modules.
MXEs enable encoded computation, which allows for shared confidential state. Zero-knowledge proofs let one prove a statement about data while keeping it hidden, useful for single-user confidentiality like identity, but they require the proving party to know the data in plaintext, making them unsuitable for applications that need shared confidential state.
FHE allows arbitrary computation on encoded data without decoding, but pure FHE suffers from performance bottlenecks and lacks proper computation verification. Arcium provides encoded computation with high throughput thanks to parallel execution, and includes cheater detection so computations run at scale and are executed correctly.
