I have already explained analogically how MPC works, but here is another analogy according to Whiteboard Crypto: Let’s say five healthcare companies want to work together to build an AI model for cancer diagnosis. They all have patient data, but sharing it directly is illegal or risky due to privacy laws. Instead, they break the data into smaller, meaningless pieces and distribute these pieces among each other. None of the companies have access to full data, but by combining their pieces, they can train the AI without compromising any patient’s privacy.

WBC's Analogy

It can be used for secret voting in DAOs (Decentralized Autonomous Organizations), where no one can see how you voted, but the system remains verifiable and trustworthy. With Arcium, players can play on-chain games like poker, where players’ hands are kept confidential without relying on a central server. In situations where DeFi users want to keep their trades private, Arcium makes provision for things like encrypted order books—a way to keep trade details secure, preventing market manipulation.

Some use cases for Arcium:

Although Arcium is based on the Solana blockchain, it aims to expand to other chains, bringing massive innovation to sectors like AI, finance, gaming, and even government services in the future. In summary, Arcium is revolutionizing how we think of data security, making it feasible and seamless for businesses, developers, and even regular users to use and share data safely in ways that were previously impossible. <a href="https://youtu.be/mj24WOShyC8?si=wBK7YKf_c5q-awZv">DYOR, do your own research</a> <a href="https://docs.arcium.com/">Arcium docs</a>

A Look Ahead

This is basically what Arcium has come to do in the web3 space. A little story: I and my 4 friends want to create a secret recipe for an amazing soup. We all want to work together, but we don't want to reveal our personal ingredients for the soup. Thinking of how to solve the problem? We get a magical box. We all put our ingredients in the box, and the box produces the soup for us. This way, we made an amazing soup, using our top-notch secret ingredients without revealing what those ingredients are.

Investors

Arcium provides opportunities for companies to train AI models using sensitive data like patient information or financial data without ever revealing that data to anyone else, revolutionizing the healthcare and finance landscape, where privacy is critical.

Data is at the core of everything we do online. From browsing the web to making online purchases or sharing files, our data can exist in three states: At Rest: Stored on a device, like photos or videos on your phone. In Transit: Moving from one place to another, like when you send an email. In Use: Being processed, like when a computer calculates your taxes. Some people already know how to protect data when it’s at rest (using passwords) or in transit (using SSL encryption), but data in use has traditionally been hard to secure.

LET'S SEE THE WORKINGS OF ARCIUM.

When you hear Arcium, think of “using encrypted data without decryption.” Full stop.

Conventionally, when you send data—say an email, a photo, or a text—it has to be decrypted before being processed, and this leaves it vulnerable to hacks. Arcium ensures that data remains encrypted even while being processed, making it highly secure.

Where Arcium Steps In.

Multi-Party Computation (MPC), which is like having multiple people work on different pieces of a puzzle without anyone seeing the full picture, is one of the technologies employed by Arcium to ensure this protection. Using this analogical explanation for MPC, when the pieces are brought together, the puzzle is solved without anyone knowing what the entire puzzle looks like. Other technologies used include Fully Homomorphic Encryption (FHE) and Zero-Knowledge Proofs (ZKPs).

Analogically, my friends and I are institutions that may want to collaborate together. The soup could be any useful result for which we are working together, e.g., training an AI model for diagnostic purposes. The secret ingredients represent sensitive information, like personal information from patients' medical history and stuff. Last but not least, the magic box is ARCIUM.

Critiquing The Analogy

Definitively, Arcium is the first parallelized confidential computing network empowering developers and applications to flexibly access trustless, verifiable, and performant computing power. Think of it as a worldwide supercomputer using cutting-edge cryptography to allow encrypted data to be processed securely without exposing (decrypting) that data. Fundamentally, Arcium aims to solve the problem of “how sensitive data is processed in the web3 space.”
