ARPA Network, the powerhouse behind Randcast, a secure on-chain verifiable random number generator (RNG), is thrilled to announce a strategic partnership with AltLayer. Beginning with integrating Randcast into the AltLayer ecosystem, both parties will deepen the collaboration and strive for the shared goal to ease the burden on Web3 builders and scale powerful Web3 applications.

AltLayer is a leading decentralized Rollups-as–a-Service (RaaS) provider for Web3 applications. Its commitment to facilitating the effortless launch of highly scalable application-tailored rollups aligns with ARPA Randcast’s goal of offering developers easy access to a range of RNGs, thus nurturing a future of fairness and transparency in the Web3 ecosystem.

With this alliance, ARPA Randcast will offer developers within the AltLayer community a trustworthy, credible, and secure tool for verifiable random number generation. Specifically, Randcast will substantially mitigate the load for developers, by offering convenient sample SDKs for various functionalities such as randomness generator (for DKG), dice rolling, winner selection, lottery draws, card shuffling, and more.

Furthermore, with its cross-chain availability, accurate fee estimation, and high-availability design, ARPA Randcast is optimally positioned to cater to the diverse and intricate needs of AltLayer’s multi-chain landscape.

“Our collaboration with AltLayer transcends mere technological integration; it symbolizes a joint commitment to reducing obstacles in the realm of Web3 development.” said Felix Xu, the CEO of ARPA Network: “As AltLayer commits to providing a range of RaaS solutions to simplify the experience for Web3 developers, we are poised to contribute a foundational layer of verifiable randomness that enhances this progress.”

Dr. Amrit Kumar, COO, AltLayer added: “Randcast and AltLayer are both working towards a similar goal, creating convenient and ready-to-use tools that can help users deploy applications without the complexity, build-times and worry. With numerous applications that will benefit from and be legitimized by achieving true random outcomes for their users or players, this collaboration brings a great addition to our rollup toolkit.”

As we look to the future, we’re excited to see the innovative applications that will emerge from this partnership. Whether it’s the creation of unique gaming experiences, transparent lotteries, or diversified NFT attributes, the combination of Randcast and AltLayer will undoubtedly usher in a new era of creativity and engagement within the growing Web3 universe.

About AltLayer

AltLayer is a leading Rollup-as-a-Service (RaaS) solution provider, offering a range of products that fast-track the deployment of highly scalable decentralized applications. Most recently, the company launched an intuitive, no-code dashboard that enables everybody — be it developers, enthusiasts, or crypto newbies — to spin up a customized rollup within 2 minutes.

Under the RaaS umbrella, AltLayer offers ephemeral rollups for short-term event-driven applications; and persistent rollups, which are ideal for use cases with a longer lifespan. Our RaaS product can save considerable capital and years of development work for teams while encouraging innovation and rapid experimentation in Web3.

About ARPA

ARPA Network (ARPA) is a decentralized secure computation network built to improve the fairness, security, and privacy of blockchains. ARPA threshold BLS signature network serves as the infrastructure of verifiable Random Number Generator (RNG), secure wallet, cross-chain bridge, and decentralized custody across multiple blockchains.

ARPA was previously known as ARPA Chain, a privacy-preserving Multi-party Computation (MPC) network founded in 2018. ARPA Mainnet has completed over 224,000 computation tasks in the past years. Our experience in MPC and other cryptography laid the foundation for our innovative threshold BLS signature schemes (TSS-BLS) system design and led us to today’s ARPA Network.

Randcast, a verifiable Random Number Generator (RNG), is the first application that leverages ARPA as infrastructure. Randcast offers a cryptographically generated random source with superior security and low cost compared to other solutions. Metaverse, game, lottery, NFT minting and whitelisting, key generation, and blockchain validator task distribution can benefit from Randcast’s tamper-proof randomness.
