What Is Arcium Crypto?

What Is Arcium?

Arcium is a parallelized confidential computing network that allows developers to perform calculations on encrypted data, enabling applications to use private information without exposing this data on-chain. Arcium is infrastructure for decentralized confidential computing.

Who Founded Arcium?

Arcium was founded by Yannik Schrade, Julian Deschler, Nicolas Schapeler, and Lukas Steiner. Previously, the team launched the privacy protocol Elusiv on the Solana blockchain.

Why Was Arcium Created?

Blockchain is a public database, but many real-world applications require a certain level of privacy. From DeFi strategies to AI prompts, from health data to payroll processing and analytics – these are critical data points that can rarely be exposed on a public chain. Arcium was created to provide the necessary confidentiality for the data already protected by encryption.

How Does Arcium Work?

What Is Confidential Computing?

In general, confidential computing enables the use of encrypted data for computation while protecting this data from unauthorized access. In crypto, this means that smart contracts can perform certain operations on private data while preserving the integrity of the underlying information.

What Is Multi-Party Computation (MPC)?

MPC provides the foundation for processing confidential information on networks. Essentially, private data is split into secret shares and computed across multiple nodes so that none of them have access to the entire dataset. According to Arcium, its confidential supercomputer design is different from traditional cloud services because it relies on independent nodes, utilizes MPC, and supports verifiable computation.

How Do MPC eXecution Environments (MXEs) Work?

MXEs are configurable confidential computing environments within which encrypted programs are defined and executed. Developers can design and deploy confidential programs within these environments, defining assumptions, cryptographic schemes, performance guarantees, and more. Multiple clusters can be utilized per MXE to provide better scalability and performance.

Why Arcium Calls Itself a Confidential Supercomputer

As mentioned, Arcium aims to become a decentralized infrastructure for encrypted data sharing. A ”supercomputer” here refers to a highly scalable confidential computing network: multiple applications can request these MXEs to perform private computations, thus utilizing a shared pool of encrypted data.

Arcium Architecture Explained

Understanding arxOS

arxOS is a distributed encrypted operating system that coordinates the execution of confidential programs across the Arcium network.

What Are Arcis and Confidential Programs?

Arcis is a Rust-based developer framework and compiler that enables developers to build programs for Arcium infrastructure. Arcis is critical to the whole endeavor because it would let developers actually utilize the benefits of Arcium’s privacy-preserving paradigm.

How Arcium Nodes Secure the Network

Arx operators provide MPC nodes and computation power for the network. Computation customers define the MXEs for execution and pay for the costs associated with computation. Delegators can stake with the operators securing the network and share in their rewards while being mindful of potential slashing conditions. In general, the network has a marketplace for confidential computation.

How Confidential Computation Is Verified

State management and orchestration are conducted on Solana. In other words, the network utilizes Solana’s settlement layer to coordinate and manage computations, enforce rules, organize queues, apportion rewards, order execution, and penalize malicious behavior. In general, Arcium’s verification mechanism is inherently public.

Key Features of Arcium

End-to-End Confidential Computing

With Arcium, all data is encrypted, including inputs, intermediate values, and outputs. Essentially, this is a critical distinction from other privacy-focused protocols and blockchains that only hide on-chain activity or certain data points like wallet addresses. Arcium emphasizes the importance of secure logic.

Programmable Privacy for Smart Contracts

With Arcium, organizations can develop smart contracts with built-in privacy features. Possible applications include sealed-bid auctions, private order books, private transfers, games with confidential moves, private compliance checks, and private AI models.

High-Performance Parallel Computation

Arcium’s emphasis on parallel confidential computation is what distinguishes it from other privacy infrastructure. The utilization of MXEs and clusters is crucial for performance, especially considering how performance-sensitive many potential applications for such a system would be. In other words, Arcium would let developers actually deploy something large-scale and useful.

Cross-Chain Compatibility

Solana is the network’s consensus layer for now, but Arcium is not a blockchain itself. The company’s FAQ states that Arcium requires an underlying consensus and data availability layer, making it essentially chain-agnostic.

What Is the ARX Token?

ARX Token Utility

The token underlies the network’s staking and governance mechanism and plays a crucial role in its economic design. In general, there is nothing unusual about it, apart from the fact that it does not have a dynamic supply. According to the tokenomics, there is a fixed supply of 1 billion ARX tokens.

ARX Tokenomics Explained

Arcium’s tokenomics are largely defined by staking, governance, fees, and supply distribution. For every computation executed on the network, 70% of fees are distributed to node operators, 20% to recovery nodes, and 10% to the treasury. At the time of writing, 20.88% of the supply was already unlocked, with the remaining 79.12% set to enter circulation over time.

How the ARX Token Supports the Arcium Ecosystem

ARX tokenholders can participate in the network’s governance. Arcium’s design is such that the more capacity a validator provides to the network, the more tokens should be staked to secure better rewards. Additionally, longer locking periods are rewarded with higher voting power. Generally, the entire design is meant to incentivize holders to utilize the token for its intended purpose.

Real-World Use Cases for Arcium

AI seems to be one of Arcium’s central use cases. AI applications can utilize Arcium to process private prompts and data, including documents, code, medical records, and research. In general, most useful AI applications would involve some level of confidentiality, and therefore benefit from being built on Arcium. The acquisition of Inpher, which focuses on confidential machine learning and MPC, supports this narrative.

Private DeFi Protocols

Confidential AI Applications

Private DeFi protocols are another central application for Arcium. The problem with on-chain DeFi is that every transaction is visible and can be traded on, leading to front-running, mimicking, and other forms of attacks. AI-driven trading and analytics would benefit from a similar level of confidentiality, which is why dark pools and other encrypted order book mechanisms are likely to emerge.

Secure Payments and Financial Infrastructure

Similar to DeFi, traditional finance desperately needs more privacy and confidentiality. This includes everything from simple transactions to analytics, where insights are often derived from encrypted and aggregated data. Payments confidentiality, hidden balances, encrypted compliance checks, and private financial data in general can all be facilitated by Arcium.

Enterprise Data Processing

Enterprises need private analytics, fraud detection, risk models, and secure data collaboration. Arcium’s value proposition is that multiple parties can compute together without handing full datasets to one central processor.

Healthcare and Sensitive Data Management

Healthcare is another sector with very specific and strict requirements for data confidentiality. While it is a long tail, the potential value is enormous, as hospitals and insurance companies handle extremely sensitive personal data.

Arcium vs Oasis Network

Oasis Network is another project that is related to confidential computing. However, Arcium is focused on developing MPC-based execution environments within Solana, which appears to be a much more ambitious undertaking than what is being attempted by Oasis.

Arcium vs Aztec

Aztec is a zero-knowledge encryption project that is deeply integrated with the Ethereum ecosystem. Arcium, on the other hand, is focused on developing MXEs and confidential computation, and it is not built on top of Ethereum. While Aztec utilizes zero-knowledge proofs to allow for some level of on-chain privacy, Arcium emphasizes shared state encryption, arguing that it is better suited for shared computation.

Arcium vs Zama

Zama is a project that is focused on developing Fully Homomorphic Encryption or FHE, which is an emerging field in cryptography. With FHE, it is possible to perform arbitrary computations on encrypted data, which is theoretically much more powerful than what is being pursued by Arcium. That being said, FHE is much more computationally intensive and has a steeper learning curve, which puts it at a disadvantage from a practicality standpoint.

Is Arcium Built on Solana?

How Arcium Integrates With Solana

Yes, Arcium is built on Solana. According to the documentation, encrypted computation happens on-chain via the Solana blockchain, whereas Arcium’s nodes are responsible for executing private data computation. In general, the relationship between Solana and Arcium resembles that of Ethereum and other privacy-focused rollups.

Is Arcium a Layer 1, Layer 2, or Infrastructure Layer?

Arcium is best described as an infrastructure layer. It is not a settlement or consensus layer, as it relies on Solana for these functions. From a practical standpoint, Arcium can be seen as a scaling solution that adds additional privacy features, and it is likely to have broader composability with other infrastructure.

Arcium Roadmap and Future Development

Mainnet Launch Plans
