What is ARPA3S (ARPA3S)?
ARPA Network, often referred to as ARPA, is a decentralized secure computation network built to enhance the fairness, security, and privacy of blockchains. The project aims to provide verifiable computation services through its threshold BLS signature network. ARPA was initially known as ARPA Chain, a privacy-preserving Multi-party Computation (MPC) network founded in 2018. Its experience in MPC and other cryptography laid the foundation for its current innovative threshold BLS signature schemes (TSS-BLS) system design. The core technology behind ARPA involves threshold BLS signatures, a form of multi-party computation where nodes collaboratively generate cryptographic proofs without any single party accessing raw data. This allows for verifiable computation without data exposure. ARPA's network serves as infrastructure for various applications, including verifiable Random Number Generators (RNG), secure wallets, cross-chain bridges, and decentralized custody across multiple blockchains. One of ARPA's key applications is Randcast, a verifiable Random Number Generator (RNG). Randcast offers a cryptographically generated random source that is tamper-proof and can be used in areas like the metaverse, gaming, lotteries, NFT minting and whitelisting, and blockchain validator task distribution. The network is designed to be decentralized, allowing anyone to run a node, and is blockchain-agnostic, aiming to adapt to multiple blockchains. The founders of ARPA are Felix Xu and Yemu Xu. Felix Xu is also the CEO, with Lei Zhang involved. ARPA operates as a computation layer that integrates with various chains and is transitioning to a dedicated Layer 1 blockchain by 2026 to further enhance privacy capabilities for DAOs and DeFi. The network has processed over 224,000 computation tasks since its inception. Learn more

ARPA3S (ARPA3S) FAQ
ARPA Network is a decentralized secure computation network designed to boost the fairness, security, and privacy of blockchains. It delivers verifiable computation services using its threshold BLS signature network, formerly known as ARPA Chain.
ARPA operates using Secure Multi-Party Computation (SMPC) and secret-sharing, enabling private smart contracts, data privacy, and scalable computational sharding. It leverages threshold BLS signatures, where network nodes collaboratively create cryptographic proofs without exposing raw data. This ensures secure transaction validation while protecting sensitive information, bolstered by cryptographic design and an economic model including an account credit system.
ARPA Network's privacy framework supports diverse applications. Key use cases include Verifiable Random Number Generation (RNG) via Randcast for gaming and NFTs, secure wallets, and cross-chain bridges for digital asset management. It also facilitates decentralized custody, privacy-preserving dApps in DeFi and AI, and credit/anti-fraud mechanisms, allowing secure sharing of sensitive data for risk management.
The ARPA token has a maximum supply of 2 billion. Its utility includes payment for computation services like Randcast, staking for network security, and facilitating community governance through voting on protocol decisions. Nodes are rewarded with ARPA tokens for participating in computations. Additionally, ARPA tokens are periodically burned to incentivize holders and manage supply.
ARPA Network serves as a foundational infrastructure for Web3, offering cryptographic trust via decentralized, verifiable computation. It empowers individuals with control over personal information in a privacy-centric internet. Designed to be blockchain-agnostic, ARPA supports a multi-chain future by integrating with diverse blockchain platforms, thus enhancing the entire ecosystem's privacy and security.
ARPA Network plans a significant transition to a dedicated Layer 1 blockchain by 2026. This strategic move aims to considerably enhance privacy capabilities, particularly for Decentralized Autonomous Organizations (DAOs) and various Decentralized Finance (DeFi) applications, building a more robust and private foundation for its ecosystem.
