memo.cash will rerad the posts from both chains, and combine the display. I post on BCH chain, they replay on BSV chain, memo,cash combines them.
*read, memo.cash will *read* the posts...
mkay, lets say it is 5 years from now & ABC-chain is defunct, the memo-protocol implementer now has no access to the post that was replied to
Blockchain won't disappear. Memo could be running one BCH archival node, and pull old post from it. New post will then be recorded on one chain only.
yes it is doable, but sounds like a pain in the ass
