I was looking into omni protocol and couldn't quite figure out some things. I'd really appreciate your opinions. I tried to look into all the bitcoin stachexchange answers, but nothing that much related to what I am asking.
At first, I thought that Omni was a whole new blockchain(they forked it from bitcoin), and then added some more code to implement contracts so that assets could be transferred.
At second, I read that omni does write data to bitcoin blockchain itself.
Question 1) why is not the omni a new blockchain at all if they forked it from bitcoin ? we can see that on github.
Question 2) let's assume, it's not a new blockchain - then this means that my second thought is correct. How does it write data to bitcoin blockchain ? I can think of one way:
P2SH Scripts, but wanted to make sure.
Question 3) if the omni is not a new blockchain at all, then how does its explorer work ? I guess, their explorer fetches all their related
P2SH Scripts from bitcoin itself . right ?
