\"What<\/figure>\n

Data availability in Web3 refers to the ability of a network to guarantee that all network participants have access to the data needed to verify a block. This is a critical ability for a Web3 network, but it has created an unexpected problem. Let\u2019s take a closer look.<\/p>\n

What is the data availability problem?<\/h2>\n

On the surface, it seems that ensuring data availability shouldn\u2019t be much of a problem. After all, you can just download a complete copy of the ledger and check if there are any discrepancies. In fact, this is what the full nodes in a blockchain network do. However, there are more to a blockchain network than full nodes, with the other main type being light nodes. For a light note it\u2019s essential not to have to download the full history of the entire chain. Additionally, this is a problem for scalability. This is why, similarly to light nodes, scaling solutions such as shard chains and rollups need other ways to prove data availability in order to be able to process transaction data efficiently.<\/p>\n
