Imagine a world where any data can be securely encrypted yet remain fully operable - a reality that Arcium is bringing to the Solana ecosystem. At Breakpoint 2024, Yannik Schrade unveiled Arcium's groundbreaking encrypted computing technology, set to revolutionize data security and privacy in blockchain applications.

Summary

Arcium is developing a hybrid-encrypted internet infrastructure that allows for secure storage and processing of encrypted data without ever exposing it. This technology, built on Solana, introduces RQL (Reactive Query Language), a purely computational stateless network that can process encrypted data efficiently and securely.

The core of Arcium's innovation lies in its use of secure multi-party computation (MPC) and a decentralized encrypted operating system. This system enables the deployment of MPC Execution Environments (MXEs), which can process arbitrary encrypted data. Arcium has also developed a custom Rust compiler, allowing developers to easily add confidentiality to their applications.

One of the most impressive aspects of Arcium's technology is its cryptographic security model, which remains secure as long as at least one participant is not compromised. Despite this high level of security, Arcium claims to be 10,000 times faster than traditional fully homomorphic encryption methods, thanks to breakthroughs in MPC protocols and hardware acceleration.

The potential applications of this technology are vast, ranging from confidential DeFi on Solana to data-intensive applications and even collaborative machine learning on encrypted AI models. Arcium's RQL network promises to be a game-changer for developers looking to add confidentiality and encryption to their blockchain applications.

Key Points:

Hybrid-Encrypted Internet Infrastructure

Arcium is building a revolutionary infrastructure that enables secure storage and processing of encrypted data. This technology allows for analysis, processing, and execution of information without ever exposing the underlying data. The system is designed to work in a trustless and efficient manner, providing a new level of security and privacy for blockchain applications.

The infrastructure is centered around RQL, a purely computational stateless network that runs entirely on encrypted data. This network can interact with data stored on Solana, process it securely, and return encrypted outputs back to the blockchain. This creates an autonomous, asynchronous execution machine capable of performing arbitrary computations on Solana.

Decentralized Encrypted Operating System

At the heart of Arcium's innovation is RQL, which serves as the first decentralized encrypted operating system. This operating system powers the RQL network and enables the deployment of MPC Execution Environments (MXEs). These MXEs are encrypted isolated environments that allow for the arbitrary processing of encrypted data.

To make this technology accessible to developers, Arcium has created a custom Rust compiler. This compiler can transform arbitrary Rust programs into a format that RQL can understand and securely process. With this compiler and accompanying frameworks, developers can easily add confidentiality and security to their applications by simply deploying them in an encrypted environment.

Advanced Cryptographic Security Model

Arcium's architecture boasts an impressive cryptographic security model that sets it apart from traditional distributed systems. While conventional systems fail if a majority of participants become compromised, RQL maintains security as long as there is at least one honest and fully collaborating participant.

This robust security model doesn't come at the cost of performance. Through breakthroughs in MPC protocols, malicious behavior identification, and the use of GPU and hardware acceleration, Arcium claims to be 10,000 times faster than fully homomorphic encryption when processing fully encrypted data. This combination of security and performance opens up new possibilities for confidential on-chain applications.

Potential Applications and Use Cases

The capabilities of Arcium's technology enable a wide range of applications across various domains. One of the most exciting prospects is the ability to build fully confidential on-chain applications, particularly in the realm of DeFi. Imagine Solana DeFi protocols operating with full encryption and efficiency, providing unprecedented levels of privacy and security for users.

Beyond DeFi, Arcium's technology can facilitate data-intensive applications, such as data aggregation or node authentication for decentralized applications (dApps) running on Solana. Perhaps most impressively, Arcium has made significant breakthroughs in encrypted number arithmetic, allowing for collaborative and federated learning of AI models. This means multiple parties can participate in machine learning processes using fully encrypted AI models without having to trust a central authority.
