The Solana-based network claims to turn standard Nvidia GPUs into an encrypted supercomputer, expanding the confidential GPU pool by 2,500x through a software-only upgrade.
Key facts
- It secured $5.5 million in a strategic funding round in May 2024, bringing total fundraising to $9 million at that time
- At launch, roughly 209 million tokens entered circulation out of a total supply of 1 billion, representing about 20.88% of the full allocation, with a market valuation of approximately $400 million
- The project has since raised over $15 million total, with backing from Jump Crypto and Coinbase Ventures
- The ARX token, which powers Arcium’s network, went through its token generation event on June 22, 2026
Summary
Here’s a question that should keep every enterprise AI team up at night: who else can see your data while it’s being processed in the cloud? Arcium thinks it has a fix. The core technology relies on multi-party computation, or MPC. What makes Blackthorn’s approach notable is that it runs on standard, off-the-shelf Nvidia hardware.
