ARTIS 1.0 and xDai Chain are very similar on the infrastructure layer. The biggest difference is the use of a single token structure in ARTIS vs. a dual token structure in xDai Chain and the use of the stable token Dai as the native coin in xDai.

The use of a stable coin like xDai has the advantage of a better predictability of transaction fees calculated in Dollar, but it also creates additional friction to get xDai in the first place.

ATS follows the logic of a triple point asset, as it was coined by Bankless. It is a commodity (pay transaction fees), a store-of-value (scarce resource) and a capital asset (needed for staking).

Performance wise these two chains are basically equal.
