I will try to explain I hope I do it good enough, will check with Rob later.
technically & legally: the original TFT is a token as result of farming IT capacity and the Rivine blockchain is used as consensus mechanism, lets call this token the Rivine TFT.
Legally spoken this TFT is a token which allows you to buy & sell IT capacity. As such certain organisations like Mazraa have sold future IT capacity by means of these TFT, Mazraa has by contract to allow their customer to buy the IT capacity by using that TFT.
After consulting with the community the Foundation suggested to organize a token launch. To do this we effectively launch a new token. Called TFT(A) on a new blockchain Stellar, lets call Stellar TFT.
This is a NEW token (TFT(A)). The foundation creates a token where the property is that each Stellar TFT(A) is backed by a Rivine TFT or has been farmed since May. Stellar works with trustlines and we as foundation make sure that the trustline is correct between the Stellar TFT(A) and the Rivine TFT. To do this safely the Foundation created atomic swap mechanism, which is super safe.
No tokens can be lost, indeed a atomic swap is used to make the conversion which means if something goes wrong you are back at original situation.
From end May (the first farming round on Stellar blockchain) all new TFT’s will be Stellar TFT’s.
So legally and ethically we are 100% in order, its up to the organizer of this new token launch to define the rules, ofcourse the organizer wants to make sure that the community follows.
But do realize the Stellar TFT is technically a newly created token with certain properties.
