The encrypted supercomputer needs hardware. DAWN delivers. We’re excited to announce that each @dawninternet Black Box will run as a fully integrated Arx Node in the Arcium network. This bridges the gap between mass-market accessibility and near data-center-grade performance.

Arcium Virtual Community Summit July 30–31

Where should we plant the Arcium flag next?

🚨☂️ New Arcium Research Just Dropped ☂️🚨 Our very own Sergiu Carpov published a new paper in CHES 2025 that introduces a fast heuristic for mapping boolean circuits to functional bootstrapping. Cutting evaluation time by 45%. @ArciumHQ continues accelerating <encryption>☂️

Arcium is not a blockchain . But with blockchains? The full design comes to life. Arcium uses proven chains for what they’re best at: consensus, incentives, and coordination.

Submissions for the Arcium Developer Fellowship have concluded! 200 builders applied to the Arcium Fellowship. 20 will be chosen. $65K on the line. Encrypted apps on Solana—this is how it starts.

Encrypted Supercomputer. Arcium.

It's starting to feel like <encrypted> summer

One of our portfolio companies quietly making significant progress behind the scenes is @ArciumHQ. A recent announcement from them that deserves far more attention: they've introduced a completely new token standard on Solana called Confidential SPL Tokens. These tokens enable encrypted balances and transfers at the token level, without compromising performance or composability. In my opinion, this could be a major driver and missing puzzle piece for adoption of on-chain privacy after all this time. What makes this so impactful is that it removes the need for separate "privacy layers" - which historically failed to gain adoption - and instead brings privacy into the token standard itself. Just a few use cases that this would unlock in order to make this more tangible: - On-chain private payroll - Confidential stablecoin payments - Hidden strategy execution in DeFi - Secure enterprise and B2B flows - Compliance-friendly privacy for institutions Because it’s usable by any smart contract, wallet, or program, privacy becomes opt-in, programmable, and - most importantly - native to the @solana ecosystem. Token standards are typical winner takes it all scenarios. It reminds me of how @metaplex pioneered the NFT standard on Solana few years ago - a standard that still dominates the NFT space today and has proven to be an enormous value driver, generating tens of millions of USD in revenue. If Arcium succeeds in setting this confidentiality standard, it could play a similar role for private value transfer as Metaplex did for NFTs - quietly powering the entire category of privacy on Solana.

5 days left to apply! 20 fellows 4 weeks of guided <encrypted> building $65K fellowship fund + prize pool @solana will never be the same.
