> Why would anyone download and save the tangle, if there is no incentive? Why do people run Steem seed, bitcoin or ethereum nodes? What about seeding torrents? There's no incentive to any of these either, yet people do it. The reason people run these network nodes is because they want a reliable on-ramp that they control to access the blockchain, which is the same reason you'd run a IOTA or RaiBlocks node. Every business or advanced user that utilizes these networks ends up running a node, which decentralizes it to some extent. > IOTA has so called perma nodes and even has to use a coordinator node to handle the technical problems, which come with this promises. I can't defend IOTA's coordinator, as it's one of the biggest problems with their technology as I see it. The only reason I mentioned IOTA a few times is because it uses the same technology principals as RaiBlocks, albeit in a slightly different way. IOTA promises to remove the coordinator at some point in the future, but we'll wait and see if/when that actually happens. If they don't, it's a huge problem. > You think they are revolutionary, because they use cool buzzwords, but you only know very little about the technology and the related problems. I hope you're not addressing me directly, because I know plenty about the technology behind these products, both in their advantages and disadvantages. I do my research and surround myself with others that do the same. I don't buy into marketing hype. *Edit* - Also I just noticed you're a brand new user, welcome to Steem! :)
