Decentralisation in general tends to promote plagerism or copyright infringement. That is if you believe the current model for copyright is effective in any way shape or form. The dplatforms in general DO NOT offer any form of copyright protection save for the agreement you sign but if you look on dtube for example you can find neumerous examples of fairly obvious "copyright infringement," Bare in mind that we are working with in a TRUSTLESS SYSTEM. This means that there is no real way to prevent copyright infringement, Ultimately the concept of copyright in this space does have to be addressed differently as if you put material up then there is potential for that work to be downloaded then reworked with no form of consent given, Dsound/dtube use a system called IPFS, This system allows you to download any works to your local drive with out any need for direct access. THIS MEANS THAT YOUR WORK CAN BE TAKEN BY ANYONE! If your concern is your artistic work is being stolen or used for something unintended then the answer is simple, Don't put that work on these platforms, Personally if someone wants to use my work for something I'm usually more than happy and increably flattered by the nod as long as I am given credit, If you want to use decentralised systems then your complaint about plagerism or copyright infringment should ultimately be reexamined. There are plenty of systems out there for copyright protection and the one thing they all have in common is they give central control to one person or entity, This presents an issue as in most forms of copyright law there is an exception for what's called "fair use." However most entities will not look at this as a presentable argument as they are for more concerned with the risk to their brand than any kind of work that might have been put in. In all honesty calling memes an artform is, in my opinion, a bit of an silly premise to begin with because most memes use many images that are already popular to begin with so if you chose to worry about copyrights in this space it seems to be somewhat redundant,
