Flow
i --(1)--> s means that you transfer an NFT from IRISnet(i) to Stargaze(s) through channel is-1(si-1). Check the channel table to find what is-1 represents.
Id
Each different flow has a unique id. In task we use flow-id to refer to a flow we want participants to follow and transfer NFT.
Style
Never-go-back: No class-id prefix removal during the transfer flow (i.e. i --(1)--> s --(2)--> i ). This means when transferring the NFT back to iris from stargaze through is-2, it will result in a new Collection created on iris, even though the NFT is back on iris.
Revisit: At least one class-id prefix removal during the transfer flow (i.e. i --(1)--> s --(1)--> j --(1)--> s --(2)--> i ). For example, when transferring the NFT back to stargaze from juno through js-1, there’s no new Collection created on stargaze. Hence a removal happened.
Backtrack: All class-id prefixes are finally removed in the transfer flow (i.e. i --(1)--> s --(1)--> i ). The original NFT on iris is back and unlocked.
