So tbh the best thing you can do to counter this on a DEX is to make it fast. Uncertainty over 400ms of ordering is soooo much less bad than uncertainty over 5 minutes. This is just so much less of a problem on Solana than slower chains.

‘if the DEX isn’t being front run by the validator set, is it really decentralized?’ twitter.com/teo_leibowitz/

Do you believe MM/HFTs will ultimately be the validators on Serum due to efficiency in sending/seeing/frontrunning txs?

I think MMs will need there to be low-latency high-throughput validators whether or not they are running them

Exactly, so aren’t we moving to a collocation 2.0 system? How to maintain fairness?

I think people are putting in effort to set up a ton of public access high-throughput validators for Serum :)

appreciate the answers, looking forward to trade there

My feeling is that “we don’t really know” is the right answer. Imagine two systems: 1. Magical collocated SGX 2. Open decentralized permission-less deployment #1 has a ton of technical risk, and needs a “trusted” party to keep the collocation safe. #2 will have higher latency.
