How many people do you expect to use the project, devs?
Hello! We expect that this number will increase from 750,000 users in 2019 to 1 million in 2021
But how are user charges and miner fees calculated?
A smart contract calculates the number of tokens required for a payment and accepts the payment. Miner remuneration is also calculated in IDM tokens. A smart contract calculates the duration and the amount of leased memory and makes the payment.
As I understant the blockchain technology is just used for this purpose.
I think you're right. I've read about it in the White paper.
