NEAR DA is an efficient and powerful data availability layer designed to help Ethereum rollup builders simplify their networks and reduce costs while ensuring they can scale like the NEAR protocol. Using Near DA has the following advantages:
Significantly reduce costs
Storing rollup calldata on the NEAR protocol is approximately 8,000 times cheaper than storing the same amount of data on Ethereum. Harness the power of NEAR’s powerful blockchain, optimizing for speed, scalability and cost. Say goodbye to high DA fees and embrace a new era of cost-effective modular blockchain solutions.
Easily verify proof
Easily verify proofs using NEAR’s trustless off-chain light client. Seamlessly access and verify on-chain storage of aggregated data. NEAR's developer-friendly interface allows for easy verification of blockchain transactions, increasing transparency and trust in the system.
Simple interaction
The NEAR protocol provides an RPC interface to easily retrieve on-chain data from anywhere. Accessing transactional data has never been easier. Experience the convenience of NEAR’s data availability solutions and unlock new potential for your Ethereum rollup.
Validium is an L2 solution for Ethereum that uses zero-knowledge proofs to scale Ethereum’s throughput. Based on the original Validium, the Near plug-in is added to its original DAC to push batch transaction data to the Near chain.
The above figure depicts the overall architecture of Validium, the architecture of Near DA, and how to combine them; Near DAC is the key part of the combination.
