RE: Walletmarks
This is a big topic to be discussed further, and my idea thereof was an immutable (in every sense of the word) piece of metadata that pointed to a wallet where a viewer may contribute to the content creator directly. This is why it must be implemented at the network level, although PtP must not be.
P.S. I have opened a new thread to discuss the implementation of APPs rewarding content here.
P.P.S. One like wasn’t enough for @Artiscience’s post above. You hit the nail on the head.
