Hey there Gembria,

The Essentia blockchain will be able to process 1,280 Transactions per second but please keep in mind that blockchain is more about compromises between decentralization and speed, rather than only an arbitrary number of TPS.
The Team will realize their own Essentia Decentralised Exchange, this is under development but there is no timeline on this as of yet.
