Distributed data availability sampling with PeerDAS and future developments

After introducing separation of execution and data using blob transactions, the next step for Ethereum is to scale the data layer. PeerDAS is a construction that allows nodes to sample data from their peers (hence the name), which works even if no node has access to the complete data. By keeping the samples in the immediate vicinity, it is more robust than traditional DHTs, so it serves as an intermediate scaling solution for Ethereum until a robust and scalable DHT is developed.
