Confidential computing

Compute on data that stays confidential

With Arcium, your data is always encrypted and never visible to Arcium or anyone else. It's the most secure kind of confidential computation, powered by the most advanced cryptography, running across the decentralized Arcium Network using Secure Multi-Party Computation (MPC).

How it works

Computation on data that's never decrypted

Your data is split into encrypted shares across a cluster of independent nodes. They compute directly on the ciphertext using Secure Multi-Party Computation, then return a verifiable result. No single node ever sees your data.

Confidential AI

The fastest confidential inference engine

Arcium Blackthorn runs and trains AI models over data that stays encrypted end to end. Inputs, weights, and outputs are never exposed, to anyone. The most secure way to deploy AI, at production speed.

Arcium powers leading blockchain teams

Confidential compute, running in production across the ecosystem.

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 encrypted bids, with an interface as simple as writing an Anchor program.

$ARX Token

$ARX captures fees from network usage, secures the network, schedules confidential computation, and governs how the protocol evolves. All network growth accrues to $ARX.

01Network Fees

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

02Staking

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.

03Scheduling

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.

04Governance

$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.

Security model

Security you can verify, not 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.

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 encrypted 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 Encryption (FHE), Zero-Knowledge Proofs (ZKPs), and more to enable encrypted 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 encrypted computation, which allows for shared private state. Zero-knowledge proofs let one prove a statement about data while keeping it hidden, useful for single-user privacy like identity, but they require the proving party to know the data in plaintext, making them unsuitable for applications that need shared private state.
FHE allows arbitrary computation on encrypted data without decryption, but pure FHE suffers from performance bottlenecks and lacks proper computation verification. Arcium provides encrypted computation with high throughput thanks to parallel execution, and includes cheater detection so computations run at scale and are executed correctly.
