Hope this is the right section to post my question.
I understand basic concepts of 1 USDT = 1 USD and backed by 1$ in Tether account, but what confuses me is how USDT token really works. All I was able to find was that it uses "omnylayer" and "all transactions of Tether are bitcoin transaction". What I am interested in is following:
1. Does Tether have it's own blockchain or uses Bitcoin Blockchain?
2. What happens if I sell my BTC for Tether, and then Withdraw it? What asset will be in my wallet? BTC? Tether? BTC's marked as redeemable for Tether?
3. When I send Tether to another Tether user, transaction being processed by BTC blockchain, meaning I'm really sending BTC's. Why can't I deposit Tethers as BTCs? Who holds private key that signs tether transactions?
4. How Tethers are being issued? I mean if price of 1 USDT fixed to be 1 $ they have to "print" tethers and follow it's circulation between users. But how the hell is this possible if it all build on top of BTC blockchain.
Anyway - I would be thankful if someone could point me to whitepaper or article, explaining Tether in as much technical details as possible.
I also want to learn about how Tether works like you do. I used it for a long time, but I did not understand it at all. Hope to read more in-depth articles on this subject.
