ARPA is a blockchain-based\u00a0layer-2 solution<\/strong>\u00a0for privacy-preserving computation, enabled by cryptographic Multi-Party Computation (“MPC”).<\/span><\/p>\nThe 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.<\/span><\/p>\nDevelopers 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.<\/span><\/p>\nWhat is the ARPA Chain (ARPA) token?<\/span><\/strong><\/h2>\nARPA Chain (ARPA)\u00a0is 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.<\/span><\/p>\nWhat Problems Does ARPA Chain (ARPA) Solve?<\/span><\/strong><\/h2>\nARPA 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.<\/span><\/p>\nAnother 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.<\/span><\/p>\nWhat is Multi-Party Computation (MPC)?<\/span><\/strong><\/h2>\nThe 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. <\/span>The latter is responsible for smart contract execution.<\/p>\nARPA Chain Protocol Layer<\/span><\/strong><\/h2>\nThe 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.<\/span><\/p>\nARPA Chain Computational Layer<\/span><\/strong><\/h2>\nThe 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.<\/span><\/p>\nConsensus<\/span><\/strong><\/h2>\nThe 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.<\/span><\/p>\nProof-of-Computation<\/span><\/strong><\/h2>\nThe Proof-of-Computation mechanism is responsible for monitoring the amount of work a node has done. The system registers the node\u2019s participation level and releases rewards based on their efforts. Specifically, the system accomplishes this by counting the triples consumed during the computational process.<\/span><\/p>\nProof-of-Security<\/span><\/strong><\/h2>\n
