🏁Near DAC

The complete zkRollup mode requires the release of data on-chain (the user needs to reconstruct the complete state) and a proof of validity (zero-knowledge proof). However, given the Ethereum configuration, publishing data on the chain incurs high gas fees, which is a problem at the L1 layer. Through the Validium model, data is stored outside the chain, and only the validity certificate is published on the chain; it can not only save gas costs, but also ensure the security and effectiveness of the data.

When data is stored off-chain, there are also other risks such as loss or tampering; using Near DA as the storage layer for data can effectively avoid these risks. And NEAR DA has a simple architecture, is easy to implement, is highly efficient, and because NEAR has the cheapest transaction fees among all Web3 networks, NEAR DA becomes a very fast and cost-effective data availability option. NEAR DA is 85,000x cheaper than issuing blob submissions on Ethereum and 30x cheaper than on Celestia.

Near's Nightshade sharding technology is capable of processing more than 100,000 transactions per second (tps) with efficient and other processing performance; the advantage this architecture provides for rollup is cost-effective data availability, making any user of NEAR DA have enough time to query transaction data.
