On August 1st, AltLayer launched a stateless Rollup client side design proposal, which builds a stateless client side using an alternative DA layer instead of Ethereum's Rollup. The stateless client side needs to ensure that the Rollup block has been published on the underlying DA layer. Once the availability of the block is determined, the stateless client side needs to ensure that the state generated by the execution of transactions in the block has also been committed in the Rollup contract.
