What Is ARPA Chain (ARPA)?

ARPA is a blockchain-based layer-2 solution for privacy-preserving computation, enabled by cryptographic Multi-Party Computation (“MPC”).

The goal of ARPA is to separate data utility from ownership and enable data renting. ARPA’s MPC protocol creates ways for multiple entities to collaboratively analyze data and extract data synergies, while keeping each party’s data input private and secure. ARPA allows secret sharing of private data, and the correctness of computation is verifiable using information-theoretic Message Authentication Code.

Developers can build privacy-preserving dApps on blockchains compatible with ARPA. Some immediate use cases include credit anti-fraud, secure data wallet, precision marketing, joint AI model training, or key management systems. For example, banks using the ARPA network can share their credit blacklist with each other for risk management purposes without exposing their customer data or privacy.

What is the ARPA Chain (ARPA) token?

ARPA Chain (ARPA) is an Ethereum token that powers ARPA Chain, a computation network that enables privacy-preserving smart contracts, data storage, and scalable off-chain transactions. The ARPA token can be used to pay for data and computation in addition to governing the future of the network.

What Problems Does ARPA Chain (ARPA) Solve?

ARPA seeks to provide relief for a variety of different issues. Like most layer 2 solutions, the protocol provides more scalability to the market. The protocol leverages a highly scalable infrastructure and computational sharding to improve performance. Additionally, the developers went to great lengths to simplify new user and developer onboarding.

Another major problem that many computational networks suffer from that ARPA helps to eliminate is incorrect data. There is always an added risk whenever computations are done off-chain. These off-chain transactions are often coming from a centralized system which makes them a weak point. ARPA integrates proprietary smart contracts to ensure that all outsourced data remains cross-referenced. The protocol goes as far as to verify the computations via a Message Authentication Code.

What is Multi-Party Computation (MPC)?

The MPC protocol is a core component of the ARPA Chain. This protocol is responsible for separating data utility from ownership. It leverages Zero-knowledge proofs to enable multiple users to collaboratively analyze data and extract data synergies. Zero-knowledge proofs are a technology that improves security by eliminating the need to share sensitive information to confirm it. Notably, the MPC protocol is split into two layers, the processing, and computational layer. The latter is responsible for smart contract execution.

ARPA Chain Protocol Layer

The ARPA Chain also leverages a dual-layered approach. The first layer is called the protocol layer. This system operates as a permissionless public blockchain. Anyone can join this network. You can join and leave as you like without any penalties. The protocol layer enables users to share their computational power to secure profits.

ARPA Chain Computational Layer

The second layer of the network is the computational layer. This system is responsible for the completion of MPC processes. These are network crucial nodes that must meet certain criteria to qualify. Additionally, this layer is where nodes earn rewards or are penalized for malicious actions.

Consensus

The ARPA Chain utilizes a variety of unique consensus mechanisms to remain valid. The Proof-of-Correctness mechanism replaces the PoW mechanism. This system accounts for the fact that, unlike a financial network, only a select few nodes are handling specific computations rather than the entire network. As such, the system was set up to enable the network to delegate certain nodes to handle code execution and remain secure.

Proof-of-Computation

The Proof-of-Computation mechanism is responsible for monitoring the amount of work a node has done. The system registers the node’s participation level and releases rewards based on their efforts. Specifically, the system accomplishes this by counting the triples consumed during the computational process.

Proof-of-Security

The Proof-of-Security system is used to verify computations conducted off-chain in TEEs. TEEs are off-chain networks that contribute to computational power. This system ensures that these parties conducted the computations correctly and in a timely manner. This component is critical as incorrect data on a blockchain can lead to problems in the future.

This was a significant milestone, enabling early developers to build DApp prototypes leveraging the power of the ARPA-BLS network. The TestNet serves as a blockchain-agnostic infrastructure for various use cases. The ARPA team implemented advanced testing and deployment strategies, including Anvil, CI/CD, Robot Framework integration, real-world emulation, performance benchmarking, and a bug bounty program to refine the TestNet. These enhancements are critical in ensuring network robustness and reliability​​.

• Token Economics and Distribution: As of November 8, 2022, the maximum and total token supply of ARPA are 2,000,000,000 and 1,500,000,000, respectively, with a current circulating supply of 1,240,000,000 (62% of the max token supply). The ARPA token is used for various purposes within the network, including rewards for completing computation tasks, payment for service fees, and collateral for security deposits​​.

• Applications and Use Cases: Randcast, a verifiable Random Number Generator, is the first application leveraging ARPA Network as infrastructure. It offers cryptographically generated random sources with superior security and low cost, suitable for use cases where fairness and transparency are essential, such as in metaverse gaming, lotteries, NFT minting, and blockchain validator task distribution​​​​.

ARPA Network’s developments in 2023 reflect its commitment to enhancing the capabilities and reach of blockchain technology. Its transition to a focus on TSS-BLS and the release of its TestNet represent significant advancements, positioning ARPA Network as a versatile and secure infrastructure for a variety of blockchain applications.
