What is Data Availability Layers ?
In blockchain and Web3 ecosystems, a Data Availability Layer (DAL) is an essential aspect that guarantees that transaction data is dependably kept and available to network users.
Its main function is to ensure that the underlying data is completely accessible for validation, auditing, and off-chain computations when blocks are offered on a blockchain without needing each participant to keep everything.
These layers enhance scalability, minimize bottlenecks, and allow rollups and other Layer 2 solutions to operate effectively while preserving security and decentralization by isolating data availability from transaction execution.
In essence, it serves as a framework that ensures openness and confidence in the exchange and retrieval of blockchain data.
