Arcium: Powering the Future of Confidential Computing in Web3 In a digital world increasingly reliant on decentralized systems, privacy and trust are paramount. Arcium is emerging as a groundbreaking solution in this space, offering a decentralized confidential computing network built to make trustless, encrypted computation a native feature of Web3 infrastructure. Its core mission is to solve one of blockchain’s most persistent challenges: the privacy-security tradeoff. Traditional blockchains prioritize transparency, often at the cost of exposing sensitive data to potential misuse. Arcium aims to reverse that by allowing computations to occur on encrypted data—ensuring both security and verifiability without revealing the underlying information. Encrypted Computing, Redefined At the heart of Arcium’s technical architecture lies Multi-Party Computation (MPC), a cryptographic method that enables multiple entities to collaboratively compute functions over their private inputs—without sharing those inputs with each other. This allows for truly confidential data processing, opening up possibilities across sectors like DeFi, artificial intelligence, and healthcare. MPC is implemented within Multiparty Computation Execution Environments (MXEs)—customizable, secure virtual machines purpose-built for encrypted computation. MXEs combine MPC with other cutting-edge technologies such as Homomorphic Encryption (HE) and Zero-Knowledge Proofs (ZKPs), enabling computations on encrypted data without ever decrypting it. Dual MPC Backends: Cerberus and Manticore Arcium employs two MPC backends to address different security-performance tradeoffs: Cerberus: Designed for environments where malicious behavior is possible, offering high security with authenticated shares to detect manipulation. Manticore: Optimized for honest-majority settings, offering significantly faster performance—especially useful in computation-heavy use cases like AI model training. This dual-engine approach allows Arcium to remain both flexible and efficient, outperforming traditional secure computation methods like Fully Homomorphic Encryption (FHE) by orders of magnitude in real-world throughput. The Inpher Advantage A major boost to Arcium’s stack came with its acquisition of Inpher, a Web2 confidential computing company that raised over $25 million in backing from global leaders like JP Morgan, Amazon, and others. Inpher’s patented MPC protocols, including Manticore, bring years of enterprise experience from banking and healthcare into the Web3 space—enhancing Arcium’s performance and credibility. Strategic Backing and Visionary Leadership Arcium has garnered strong support from both venture capital and the blockchain elite. The project has raised $9 million in total funding, including a $5.5 million strategic round in 2024 led by Greenfield Capital. Other participants include: Coinbase Ventures Heartcore Capital Longhash VC L2 Iterative Ventures Smape Capital Staking Facilities Everstake Renowned angel investors also back the project, including: Anatoly Yakovenko (Solana) Keone Han (Monad) Mert Mumtaz (Helius Labs) Kenny Li (Manta Network) Lucas Bruder (Jito) Arcium is also part of NVIDIA’s Inception Program, and is actively collaborating with enterprises in finance, healthcare, and government sectors. Leading the project is CEO Yannik Schrade, a cryptography expert with academic grounding in law, computer science, and mathematics. He is supported by a world-class team of PhDs and engineers, including talent from Inpher. A Long-Term Bet on Privacy-Preserving Web3 Arcium launched a community sale on CoinList in March 2025 with a $200 million fully diluted valuation (FDV) and a bold 100% token unlock on TGE which will happen on Q3 —yet still drew strong demand, underlining long-term investor belief in the team’s vision and execution. Arcium is building the infrastructure for a future where privacy is a feature, not a compromise.
thank you for the very comprehensive post Banter! just a quick note: just make sure when prompts are used that you are really absorbing the knowledge and growing along with it. It's a great tool but can also be utilized and trusted a bit too often nowadays We use MPC exclusively for our decentralized confidential computing. We can use ZKPs for very specific use cases and we don't use HE we actually use something called additive secret shares which is similar, but MPC is still the only PET we use for our core technology
@commit_ted @ArciumHQ @serloost @aberamaaa Oh wow this is the second project I know that uses MPC tech It's definitely intriguing
@commit_ted @ArciumHQ @serloost @aberamaaa One thing I don't understand is why arcium is only available on sol network.
@commit_ted @ArciumHQ @serloost @aberamaaa the backing list is super stacked .. and arcium is still under the Rader
@commit_ted @ArciumHQ @serloost @aberamaaa This explained a lot "Multi-Party Computation (MPC), a cryptographic method that enables multiple entities to collaboratively compute functions over their private inputs without sharing those inputs with each other." Great insight
