Yona Network integrates with Nubit for Data Availability layer deployment

Yona Network and Nubit Integration explained

Yona Network, the fastest Bitcoin-based L2 network running on the Solana Virtual Machine (SVM), integrates with Nubit to extend the capabilities and scalability of the Yona Network ecosystem. Yona integrates Nubit for its use as Data Availability (DA), as using Bitcoin L1 as the DA layer is prohibitively expensive: it would account for a large portion of the rcosts of a transactions. Therefore, Yona only stores the checkpoint commitments on Bitcoin as of L1, while all other data can be stored in a DA layer, Nubit.

The DA for L2 ensures that block producers properly publish the transaction data of their blocks on the data availability layer, allowing network participants to download and access these data blocks. This verifies the authenticity of the data and that the data downloaded by users is faithfully represented and stored at specific nodes in the network. 

With the help of data availability sampling (DAS) allows network participants to guarantee the full availability of the block data without requiring participants to fully download it, which allows lightweight nodes, which are managed by normal network participants, to check the availability of the full state by requesting a few positions in the state randomly. If enough lightweight nodes successfully check the state, DAS guarantees full data availability.

Nubit Features  as a DA in the Bitcoin ecosystem

The recent surge in Bitcoin transaction records due to BRC20, Runes, and other technologies has resulted in over 14 GB of data stored on the Bitcoin blockchain, leading to significantly high costs. This development highlights the critical need for an efficient and cost-effective data availability layer for the Bitcoin ecosystem. Riema Labs initiated Nubit, the first native Bitcoin data availability layer, guided by the principle of trust minimization.

The diagram below illustrates Nubit’s benefits, including inheriting security from Bitcoin, minimizing trust, and native Bitcoin compatibility. It showcases Nubit’s core elements: the consensus mechanism and data availability, each supported by Bitcoin.

At a fundamental level, Nubit’s architecture is relatively straightforward:

• Nubit-node: The backbone of the Nubit network, managing consensus and network interactions for the blockchain. This component enables the creation, synchronization of new blocks, block headers, and, crucially, data sampling from blocks using innovative KZG commitments.
• Nubit-validator: Hosts the chain's state machine, responsible for staking, transaction processing, and other core functions.
• DAS (Data Availability Sampling): Ensures light clients that the data in the block headers they are verifying is readily available on the network.

Nubit’s reliability and data processing are further enhanced by other technologies it offers:

• KZG Commitment: This unique feature uses validity proof (based on KZG) to ensure blocks are encoded correctly. It also enables users to retrieve necessary data through KZG opening proofs instead of Merkle proofs, significantly increasing retrieval speeds while maintaining data integrity and security.
• Modular Indexer: This stateless execution layer allows existing indexers to perform computations in a permissionless and trust-minimized manner for meta-protocols such as BRC-20 on Bitcoin. This innovative approach expands traditional indexer capabilities, providing a more flexible and secure environment for complex computations. It is expected to bridge the gap between Bitcoin layer-1 and BRC-20 applications, promoting the Bitcoin ecosystem's growth.

Moreover, like Yona, Nubit integrates with Babylon Chain, allowing secure Bitcoin staking within Nubit to create a secure and scalable data availability layer. This fosters organic synergy with the cohesive integration of various ecosystem components and levels around Bitcoin, inheriting Bitcoin’s economic security. Another noteworthy integration of Nubit is with Polyhedra. Polyhedra's innovation in zk-SNARK-based signature aggregation protocols minimizes communication overhead between validators, allowing Nubit to scale its consensus validator set to hundreds of thousands, significantly improving the decentralization of the Bitcoin DA system.

Thus, the most important aspect that sets Nubit apart is its Bitcoin-native design that seamlessly integrates with the existing Bitcoin infrastructure and security model. This differentiates it from existing standalone or Ethereum-native data availability layers such as Celestia. Nubit’s hybrid and modular approach, utilizing full and light nodes with KZG commitments and various integrations, ensures data integrity and enables efficient data recovery even in extreme scenarios. Even in the event of a complete network failure, Nubit nodes can still recover data using full nodes and KZG commitments submitted in Bitcoin. The combination of these technologies and integrations allows Yona Network to secure reliable DA while significantly reducing transaction costs.
