Blockchain Dragon

A huge dragon that monitors and feeds the blockchain with its inexhaustible energy. It could seem that the dragon is blocked by the chains that surround him. Instead, the dragon of the blockchain is made of pure energy and can move through the infinite network of chains without problems, protecting and keeping them in efficiency. Is he a lonely spirit or are there other creatures that animate the Blockchain? Surely, if there is a guardian there is also someone to beware of!!
