What is DA? DA stands for Data Availability, also known as data availability, which plays an extremely important role in all current Blockchain platforms. So what is DA and what are the things surrounding DA? Let’s find out together in the article below.
To understand more about DA, people can refer to some articles such as:

Overview of DA
DA is an abbreviation for the phrase Data Availability, roughly translated: Data availability in Blockchain allows all information and data on the Blockchain to be publicly accessible by any individual or organization. and transparency. This ensures the integrity of data on the Blockchain and also ensures the most basic features of every blockchain.
Data Availability brings the following advantages to blockchain:
- Ensuring the integrity of the Blockchain.
- Ensuring decentralization, transparency and reliability of the Blockchain network.
- Users and organizations can use DA to research target users and customers.
- Allows anyone, anywhere who only needs the internet to access data on the Blockchain.
It can be seen that among the three factors surrounding a transaction including execution, consensus and data availability (DA), DA is the element that constitutes decentralization and security for the Blockchain network.
Some terms related to DA
There are a number of roles in Blockchain that are directly related to DA including:
- Light Client: Light Clients also participate in the process of checking the validity of transactions through full nodes, but Light Clients only download some necessary information, not the entire Blockchain. So they are very “Light”.
- Full Node: Nodes will store the entire Blockchain transaction history and also participate in the transaction authentication process. Besides, the Full Node serves as a reference for the Light Client to authenticate transactions.
Some outstanding issues of the DA
Up to now, the market has always focused on the scalability of blockchain such as using Parallel Execution, Sharding, Rollup or simply increasing block size. However, today people do not care too much about the faster the Blockchain, the more the number of blocks produced, the heavier the Blockchain will be. Eg:
- Bitcoin’s blockchain weighs 418GB with a growth rate of about 20% per year.
- Ethereum’s blockchain weighs 1T with a growth rate of about 30% per year.
- Solana generates 1GB per second.
It can be seen that the heavier the blockchain, the fewer people running full nodes because the cost will be very high, making the network more centralized.
Some Current SKIN Solutions
Celestia – The First Modular Blockchain Platform
Celestia is one of the new generation Modular Blockchain models. Unlike Monolithic Blockchain where all the issues surrounding a transaction including execution, consensus and DA are also done on one layer, with the Modular Blockchain model, the above processes will be separated. Execution will be done at a different layer than the consensus and DA process.
With this new technology, projects can fully develop and choose Celestia as a consensus layer and DA. Projects can focus on their strengths and deliver security and decentralization at Celestia.
Anytrust – Offchain Labs’ technology with Arbitrum Nova
Arbitrum Nova uses Anytrust technology to focus on scalability instead of focusing on security and decentralization like Rollup technology. For Rollup technology, the data is optimized in the form of call data then sent to Layer 1 for consensus. But with Anytrust technology, data will be stored offline, only the hash of the transaction is sent to Layer 1.
By bringing DA out on-chain, transaction costs on Arbitrum Nova are much lower than Arbitrum Nitro and transaction speeds are significantly improved.
Similar to Offchain Labs’ Anytrust technology, we also have a number of equivalent solutions such as zkPorter from zkSync or Validaium from StarkWare.
Summary
DA is one of the issues that has received little attention but has been extremely important for Blockchain platforms for a long time. Hopefully through this article everyone can understand more about what DA is?
