The Data Availability Problem with a ZK Polygon. Options for data posting: 4844, Self, Validators
The data availability problem is a significant issue in the crypto space. Ethereum aims to solve it through complex cryptography and the dank sharding roadmap. Storing and serving data is expensive, and it is uncertain how long validators will store the data or if they will store it at all. If even a small percentage of validators withhold data, it poses a problem. Ensuring data availability is a challenge, and research is being conducted on scalable solutions. The cost of storing data falls on the individuals storing it, and if it becomes economically inefficient, data may be discarded, leading to a loss of availability. The design space for research on data availability is vast. Providing options for users, such as falling back to Ethereum L1 for payment, can address the issue for different types of players in the ecosystem.
