Trustless and scalable confidential execution for AI, blockchain, and beyond.

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).
General-purpose confidential computation on the Arcium Network. Power sealed-bid auctions, dark pools, and confidential transfers with C-SPL, the Confidential SPL-Token Standard, native to Solana.




























Arcium Blackthorn™ is the fastest and most secure confidential inference platform in the world. Run and train models over data that stays encrypted end to end.
Explore Confidential AI ›A decentralized network for confidential computing, powering confidential AI and blockchain applications across the globe, verifiable and confidential by default.
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.
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.
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. ”

We're pushing the frontier of applied cryptography. The breakthroughs that make confidential AI and computing practical at scale start here, in our research.
Cerberus Secure Computation via Blockchain-Enabled Maliciously Secure MPC
$ARX captures fees from network usage, secures the network, schedules confidential computation, and governs how the protocol evolves. All network growth accrues to $ARX.
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.
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.
