According to Foresight News, Ethereum co-founder Vitalik Buterin has summarized the research on Ethereum block construction up to August 7, 2024. Buterin noted that there is a consensus on allowing multiple participants to contribute transactions that must be included in a block. However, there is ongoing public debate on whether the 'last mover' issue can be avoided. He expressed optimism, stating that the topic of block construction is beginning to show promise.

Previously, Max Resnick proposed a new design called Braid, which is based on the simple idea of running many instances of Ethereum consensus in parallel.
