Ethereum's founder, V God, hosted a discussion at the Ethereum Research forum today, in which he outlined a scalable data chain model without commissions with proof of fraud-free data availability. According to God V, the fraud-free data availability check scheme retains more features of traditional non-segmented blockchains. He also proposed a possible design that includes an existing base chain, "similar to an Ethereum-style non-scalable blockchain, and anyone can post transactions to that blockchain." Here, users It will be able to pay a fee and send a special type of transaction containing a data commitment, and the block proposer / miner can then perform a data availability check on that transaction to verify that the data is available. V-God also extended how to accept only blocks that pass each availability check, and that data availability sampling will "completely and absolutely" depend on security.
