About Nubit

Nubit is a technology firm focused on enhancing the capabilities of the Bitcoin network by developing a modular blockchain infrastructure. The company was founded by Yu Feng, a computer science professor at the University of California, Santa Barbara (UCSB), who applied a decade of his academic research in areas like zero-knowledge proofs, security, and blockchain technology to the venture. Feng's background is in programming languages, program analysis, and security, with a Ph.D. from UT Austin, which directly informs the company's technical approach.

The core of Nubit's business is its Data Availability (DA) layer, a solution designed to address Bitcoin's inherent limitations in data throughput and transaction costs. This DA layer acts as a foundational service for developers building on Bitcoin, supporting applications such as Layer 2 solutions, Ordinals, price oracles, and indexers. By offering a more scalable and cost-effective way to store and access data, Nubit aims to reduce the burden on the main Bitcoin network while inheriting its security. The company's technology leverages a high-performance consensus algorithm, Data Availability Sampling (DAS), and zero-knowledge proofs to manage a large network of validators and ensure data integrity without requiring every node to download entire data blocks.

Nubit's business model centers on providing this infrastructure to developers and projects within the broader blockchain ecosystem. The company has extended its support to major Layer 2 frameworks like Polygon CDK, OP Stack, and Arbitrum Orbit, indicating a multi-chain strategy beyond just Bitcoin. This positions Nubit to serve clients in emerging sectors such as AI, SocialFi, and GameFi that require robust, scalable data solutions. The company has secured significant financial backing, raising a total of $12 million in funding, including an $8 million seed round led by Polychain Capital with participation from Animoca Brands, Spartan Group, and others. This capital is being used to advance the development and launch of its mainnet, following successful Pre-Alpha and Alpha testnet phases that attracted over 150,000 users.
