I think High-frequency trading and Atomic Swaps are two different directions,
For Peatio 3.0 we are planning to release distributed exchange which allows interconnecting to each other for settlement.

I think further development for interconnecting exchange lies in support to FIX protocol and advanced arbitrage systems.

Hello Everyone,

We would like to announce Peatio v1.6.0 release on the Rubykube fork:

https://github.com/rubykube/peatio

We are on the way to support ERC20 within 2 releases.
We recently moved all hardcoded currency into dynamically configuration currency and trading pairs.

Please find below our release notes:
https://github.com/rubykube/peatio/blob/master/docs/releases/1.6.0.md

Kind Regards and Contributors are welcome.
We have a telegram room on t.me/peatio

Rubykube Team,
Louis
