A Cryptocurrency Without a Blockchain Has Been Built To Outperform Bitcoin (technologyreview.com)

An anonymous reader quotes a report from MIT Technology Review: Bitcoin isn't the only cryptocurrency on a hot streak -- plenty of alternative currencies have enjoyed rallies alongside the Epic Bitcoin Bull Run of 2017. One of the most intriguing examples is also among the most obscure in the cryptocurrency world. Called IOTA, it has jumped in total value from just over $4 billion to more than $10 billion in a little over two weeks. But that isn't what makes it interesting. What makes it interesting is that it isn't based on a blockchain at all; it's something else entirely. The rally began in late November, after the IOTA Foundation, the German nonprofit behind the novel cryptocurrency, announced that it was teaming up with several major technology firms to develop a "decentralized data marketplace."

Though IOTA tokens can be used like any other cryptocurrency, the protocol was designed specifically for use on connected devices, says cofounder David Sonstebo. Organizations collect huge amounts of data from these gadgets, from weather tracking systems to sensors that monitor the performance of industrial machinery (a.k.a. the Internet of things). But nearly all of that information is wasted, sitting in siloed databases and not making money for its owners, says Sonstebo. IOTA's system can address this in two ways, he says. First, it can assure the integrity of this data by securing it in a tamper-proof decentralized ledger. Second, it enables fee-less transactions between the owners of the data and anyone who wants to buy it -- and there are plenty of companies that want to get their hands on data.
The report goes on to note that instead of using a blockchain, "IOTA uses a 'tangle,' which is based on a mathematical concept called a directed acyclic graph." The team decided to research this new alternative after deciding that blockchains are too costly. "Part of Sonstebo's issue with Bitcoin and other blockchain systems is that they rely on a distributed network of 'miners' to verify transactions," reports MIT Technology Review. "When a user issues a transaction [with IOTA], that individual also validates two randomly selected previous transactions, each of which refer to two other previous transactions, and so on. As new transactions mount, a 'tangled web of confirmation' grows, says Sonstebo."

    3) can the supply be controlled by government and bank
    4) processing fee cost is essentially near zero for the entity processing it, like banks - and that include processing monetary fee and amount of time

Like it or not, baring anarchy and exchanging "caps" in a post apocalyptic world, all our economies and governmental monetary policies are based around that. I call that a condition "sina qua non" and all dreamer out there wanting to escape "government grasps" don't get what society is based on and why it is that way. Those who never learn from history...
    (1) is important because without it you have no valid currency which can be used for exchange. Wild fluctuation make buyer think twice and maybe push a buy the next day/month, because next day the currency could be worth twice what it is now. Seller refuse for the contrary reason, it could be valued as half the value the next day/month.
    (2) like it or not is important because without it you may as well go back to limited monetary policies based on the gold standard... There is a reason all countries switched to a standard which does not limit the amount of monetary supply. You are essentially stringing the economy if you limit the total amount of issuable currency (assuming the amount is something low like 50 millions bitcoins, and not a technical limitation like 2^64-1). Like it or not but current economy are not based on limiting the total supply
    (4) is simply a question of adoption. If you have processing fee of 20+$ like today, or take minutes to close and be validated, then there is no way anybody with a sane mind will adopt it as a currency, it will stay niche.


    That is why essentially I think ZERO of the crypto currency existing today will be anything but either a scam, a niche commodity, used for money washing, or a speculative bubble.

On a blockchain, this would be something like double-spending, and one of two transactions would quickly be invalidated. Since IOTA allows parallel branches to exist for indeterminate amounts of time, what happens when conflicting transactions are discovered? Potentially, you would have to roll back a very long chain of other transactions - but that same branch may have already given rise to many, many other branches in the tangle.

Grossly oversimplified explanation: Deflation is almost always bad because it dis-incentivizes investment and creates perverse incentives. (why invest if your money will grow in value without the risk?) High amounts of inflation are bad because economic growth and wage growth cannot keep up and it wipes out the value of assets. Modest amounts of inflation force people to take reasonable risks to stay ahead of inflation but its low enough that economic growth can keep pace or get ahead.
