What is Data Availability Problem?
The term “data availability problem” is a critical challenge that demands attention. This predicament revolves around ensuring that all nodes within the network can verify the publication of complete data when a new block is generated.
The core idea behind the data availability problem is to establish a mechanism where nodes can be confident that every piece of information within a block has been successfully disseminated across the network.
At its essence, the issue arises when a block producer fails to release all the data encapsulated within a block. Without complete data visibility, it becomes impossible for the network to ascertain the presence of any concealed malevolent transactions. This poses a serious threat to the security and transparency that are fundamental to blockchain technology.
Efforts are underway to devise effective solutions to the data availability problem. Blockchain experts and developers are exploring innovative approaches to ensure that every node within the network can reliably confirm the dissemination of complete data for each new block.
Avail’s working mechanism
Avail’s mission is to enhance the scalability of blockchains within and beyond the Polygon ecosystem. Inspired by the efficiency of Blob Storage in Web 2, Avail employs a similar architecture for optimal storage of large amounts of unstructured data.
Blob Storage, known for its scalability and cost-effectiveness, utilizes a binary large object (blob) structure, enabling the storage of data blocks in designated storage areas. Avail leverages this concept to enhance scalability and reduce fees for Rollups, ultimately meeting the growing data demands of blockchain networks.
The operational mechanism of the Avail network unfolds in several key steps:
- Data Blob Attachment: Avail takes a data blob from Validium or Sovereign Rollup and attaches an application ID, simplifying data indexing by tying all transaction data to a specific application.
- Erasure Coding for Redundancy: Avail extends the data blob through erasure coding, introducing redundancy to the data to enhance security and make it more resistant to interception by nodes.
- KZG Polynomial Commits: The network commits the data using KZG polynomial commits, ensuring that the data is seamlessly associated with the Avail block header.
- Decentralized Consensus: Blocks are proposed and distributed to a decentralized network of validators, facilitating consensus and the inclusion of the next block in the blockchain.
- Validity Proof for Immediate Verification: Avail’s use of Validity Proof, instead of fraud proof, allows Light Clients to ensure state accuracy and data availability immediately after completion. This eliminates the need to wait for a testing period, streamlining the validation process.
