- Data Availability (DA) is important for blockchain because it allows data to be accessible and verified by users. It helps ensure security, especially for rollups on Ethereum.
- Rollups process transactions on cheaper chains but rely on Ethereum's main network for security by posting necessary data. This means Ethereum validates transactions and can handle fraud cases effectively.
- The future of Data Availability includes new methods to lower costs and improve scalability, like Danksharding. This could make it easier to store data efficiently while maintaining security.
