Professors From 7 US Colleges, Including MIT and Stanford, Have Teamed Up To Design a Cryptocurrency Capable Of Processing Thousands of Transactions a Second (fortune.com)

Some of the brightest minds in America are pooling their brain power to create a cryptocurrency that's designed to do what Bitcoin has proved incapable of: processing thousands of transactions a second. From a report: Professors from seven U.S. colleges including the Massachusetts Institute of Technology, Stanford University and University of California, Berkeley have teamed up to create a digital currency that they hope can achieve speeds Bitcoin users can only dream of without compromising on its core tenant of decentralization. The Unit-e, as the virtual currency is called, is the first initiative of Distributed Technology Research, a non-profit foundation formed by the academics with backing from hedge fund Pantera Capital Management LP to develop decentralized technologies.

Bitcoin is the original cryptocurrency and the first payment network to allow parties to transact directly without needing to trust each another or to rely on a central authority. Yet, while it has built a following among developers, anarchists and speculators, mainstream adoption remains elusive. That's in no small part the product of its design, where inbuilt restrictions have constrained its performance and scalability and, as a result, reduced its usefulness as an everyday unit of payment, DTR said in a research paper. The academics are designing a virtual coin they expect will be able to process transactions faster than even Visa.

      Double spending with bitcoin is harder than just getting 51% of the available CPU power. For it to be effective, you also need to find someone willing to sell you something in exchange for bitcoin, something valuable enough to cover the cost of that much CPU power. Then you need to get them to just give it to you like that, without using an escrow service, without waiting for the payment to settle. Then you need to be sure that this person will not try to get revenge, either through the court or through a hitman. This is a rich person, someone who can afford a hitman.

      Remember that the 51% doesn't allow you to steal people's money: it only allows you rollback transactions that already happened. You still need to figure out how to execute the second half of the scam.

  2. Have they not heard of lightning? by mysidia · · Score: 4, Funny

    Don't get me wrong.... its a fun experiment to try and come up with new experimental types of blockchains and transactional systems.

    But Bitcoin already has a pragmatic solution called the Lightning Network that uses second-layer networks allowing wallets to safely transact off the chain, resulting in extremely high scalability and low fees --- as a result it is not even limited to "Thousands of transactions per second".... indeed to be a competitor in payment processing, Millions of Transactions per Second may be required ---
    so when you think of scaling; just making a native blockchain capable of thousands of TPS sounds impressive at first, at first, But its really not much in the grand scheme of things --- when you're talking about transitioning from experiment to real-world use.

    Ultimately, layering additional peer-to-peer networks with certain safeguards and no lower bound that says a transaction takes at least X minutes, is a smart approach.

      Lightning does use the blockchain, but it uses it as a settlement layer which makes a lot more sense than storing everyone's coffee payments on each others computers.

      Lightning doesn't route - it bases its functionality on open problems in computing. Spend a hour (if you must watch at 1X) on these two to get a good summary of its problems:

      It's also worth mentioning that LN enables sharding of the blockchain itself, since it enables atomic swapping of currencies. Let's say in the near future 1 million computers are willing to be a node (blockchain node, not LN node) for a cryptocurrency. If they all stored the same blockchain, that may be more redundancy and security than is necessary. So Bitcoin could fork into say 1000 separate blockchains (similar to Bitcoin Gold and Bitcoin Cash but on a much greater scale). Then 1000 blockchains each get replicated 1000 times. The LN can run on top of those blockchains to smooth out exchanges between the different currencies. Each individual user may only need to hold coins on a half-dozen currencies, the exchange and balancing of which are done automagically. This effectively means the settlement layer has greater capacity and can be used for smaller sums of money. Whereas with only one blockchain (Bitcoin) you may only close out a channel every year (or whatever frequency LN detractors have calculated), with 1000 currencies you could close out multiple times a day.

    Ripple has some serious issues, for instance the company and founders still holding over half of the total coins, and they have the ability to freeze the network or an individual account. Ripple isn't fully decentralized; parts of it are firmly under control of Ripple Labs.

    Many banks have used Ripple, but in most cases the purpose was to experiment, with Ripple being a convenient mechanism to manage transactions and settlement outside of the banks' own bloated and antiquated systems which lend themselves poorly to experimentation.
