For visibiility, a discussion on IOTA and IoT, from the Iota unmoderated thread
PoW is a prevention against sybil attacks. The PoW, which is necessary is not very much and will then be of minor significance, once the IRI will be changed for industrial appliances.
why PoW at all? well, you have a synchronized, soon to be decentralized system, where data-integrity needs to be established through the "confirm 2 tx before you conduct a new one" thingy. pretty solid architecture. what would you take?
for the computational power: you ever heard about JINN?
the ternary processors will conduct the necessary PoW in fractions of a second. Right now, I need just a few seconds with my CPU so that's completely fine for users. the IoT will be handled differently, but everyone was told that like a hundred times.
the consensus furthermore will be established in a decentralized manner, once the monte carlo random walk is enabled, because right now, like you know, the coordinator is centralizing it, for security and topology-reason. (the wittnesses in BB btw too)
So what is your point? that the PoW is to heavy? well it isn't very long.
That we have no decentralization? well we will have it in approx. july 2017
That it's not suitable? why not, what is still missing?
That is funny, since last time I checked Iota, the PoW didnt help against Sybils, and instead people were asked for social proof to join the network, that ist he Sybil prevention.
No, that is not my point that "pow is heavy", read my post again and try really try hard to see the big picture. No offense, just open your eyes.
Hardware, Jinn, if you place one of these on a chip, someone will place 100 000 of them together in one big chip, call it a Specialized Processing Unit, and it would then be able to outpace and outrun at least 100 000 of other smaller chips. What I mean is, at IoT power levels, can not ever compete with a normal PC, lulz that should be obvious and clear as blue day, no matter if you place "specialized non-existent magic hardware" on it or not.
Hence, PoW and IoT are oxymorons. Pick one. You cant protect your IoT devices with PoW scheme.
But you can, with a signature based scheme such as Byteball, and other cryptocurrency, even DPoS works better. See IOTA developers and fans, say, "Oh but IoT will not be a full node, it will only send/sing transactions", Well duh, obviously, any fucking cryptocurrency can delegate a chip to be dumb and trust another full node. What good cryptocurrencies do is, allow the IoT chip to send/receive transactions with its own keys - by signing shit just as other full wallets, and get the protection from scammers and attackers as the rest of the network. Spicy isnt it.
Of course, IOTA, bragging about IoT so much, and now we hear from its supporter "IoT will be handed differently." WHAT. OK.
