I think that is matter for the price of Ethereum and EOS. EDC Blockchain works on basis of EOS blockchain. Thanks this it has a LPoS blockchain and low commissions.
All I found on the site is that it is an independent blockchain, as well as a mention of the operation of this blockchain using the protocol Graphene. This protocol was first presented in 2017. As far as I remember, the EOS blockchain started in the summer of 2018. In general, I did not find technical details of the EDC blockchain.
Where did you get the EOS blockchain information?
The fastest transactions thanks to the 2.0 Graphene technology
EDC cryptocurrency mining operates on the LPoS algorithm (Leased-Proof-of-Steak)
