Taking Things Off the Chain Per Se

Since the early days of Bitcoin, people saw this like a multiple legend which is the blockchain and we're saying, oh yeah, maybe I could use it also to put my own data there. People were putting all kinds of messages or images and stuff like this but this is a problem. Like you force all the nodes in the network to actually store those data up for you - which increase the cost of running another. So that's where this idea of taking things off the chain per se has come into the focus. That's one way to explain a little bit about what's going on with RGB.
