First of all, they suggested the elimination of 30 validators not because of any improvement or benefit for dYdX v4 but because of profitability of validators. This is such a terrible idea. Most dYdX v4 validators have not been profitable since genesis, yet have brought immense value and contributions to dYdX v4 willing to subsidize the costs because they believe in the potential of the project, why stop this? Why stop all these ‘free’ contributions to dYdX v4 from 30 top validator entities? Makes no sense and only damages dYdX v4.
Secondly about @eguegu mention of consensus. dYdX already recommended Tokyo as the infra location for best latency and hence best trader experience so if you really want to improve trader experience you should eliminate all the validators not based on Tokyo, not the ‘smaller 30 validators’. Also your comment ‘there is virtually no demand from traders for greater decentralization’, of course users don’t care about the underlying tech, it was dYdX team that decided to decentralized all components of dYdX including the orderbook and matching engine (first DEX to achieve this) and that’s why they migrated from v3 to v4
