Leading MPC protocol pivots to TSS-BLS, building better permissionless computing infrastructure
SINGAPORE / ACCESSWIRE / 18 October 2022 / ARPA chaina blockchain-based solution for secure privacy-preserving computation enabled by Multi-Party Computation (MPC), is changing to ARPA Network (ARPA) as it shifts focus from general MPC to Threshold BLS Signature Schemes (TSS-BLS), a subset of MPC.
ARPA Chain was founded in 2018 as a privacy-preserving MPC network, and the Alpha Mainnet has completed over 224,000 computational tasks in the past 2.5 years alone. Its experience in MPC and cryptography laid the foundation for its innovative TSS-BLS system design and led the team to the new ARPA.
ARPA is a blockchain-adapted decentralized secure computing network that uses mature cryptographic algorithms. It aims to further push the boundaries of blockchain and ultimately enable more blockchain use cases via the Threshold Signature Scheme – from serving as verifiable random sources for the metaverse, games and NFTs, providing wallets with social recoverability and flexible key management policy, and ensuring cross- chain transactions. Since TSS networks are sometimes criticized for being slow, ARPA designed a unique clustering mechanism that allows multiple groups of nodes to participate in the completion of BLS signature tasks simultaneously, significantly increasing throughput.
On top of that, to better meet the needs of developers across multiple ecosystems, ARPA is building the network to support multiple blockchains and allows developers to customize signature policies according to different security levels required by different applications. Meanwhile, the decentralization feature allows the participation of individual node operators in a permissionless manner, helping to spread risk by eliminating the possibility of a single point of failure.
While ARPA’s nature of decentralization strengthens physical manipulation protection, its token economy design derived from game theory also helps to clearly limit malicious intent and significantly improve the network’s level of security. Therefore, the network’s utility token $ARPA plays a critical role in maintaining a permissionless and self-sustaining ecosystem. For example, the $ARPA token can serve as incentives for completing BLS calculation tasks. When a client starts a computational task, the ARPA system distributes the task and summons participants to help complete it, promising ARPA tokens if successful. On the other hand, the client may have to pay a service fee or make a deposit when setting up compute nodes in $ARPA as well.
Going forward, ARPA will serve as the infrastructure for many blockchain applications, including verifiable random number generator (RNG), secure wallet, cross-chain bridge, and decentralized repository across multiple blockchains. While working intensively on the development of the network, the team is also building ARPA’s first showcase, Randcast, a verifiable RNG that offers chain-generated random sources while being secure and verifiable at low cost. Randcast can be used across multiple blockchains in a wide range of use cases where fairness and transparency are critical, including metaverse gaming, lottery, NFT coining and whitelisting, key generation and distribution of blockchain validation tasks. The ARPA team is working on the Deevnet launch in Q4 2022, and the Mainnet launch in Q1 2023.

About ARPA
The ARPA Network (ARPA) is a decentralized secure computing network built to improve the fairness, security and privacy of blockchains. ARPA Threshold BLS Signature Network serves as the infrastructure for verifiable Random Number Generator (RNG), secure wallet, cross-chain bridge and decentralized custody across multiple blockchains.
ARPA was formerly known as ARPA Chain, a privacy-preserving Multi-party Computation (MPC) network founded in 2018. The ARPA Mainnet has completed over 224,000 computational tasks in recent years. Our experience in MPC and other cryptography laid the foundation for our innovative BLS signature system design (TSS-BLS) and led us to today’s ARPA network.
Randcast, a verifiable Random Number Generator (RNG), is the first application to leverage ARPA as infrastructure. Randcast offers a cryptographically generated random source with superior security and low cost compared to other solutions. Metaverse, gaming, lottery, NFT minting and whitelisting, key generation and blockchain validation task distribution can benefit from Randcast’s tamper-proof randomness.
