- More Exoskeletons Seeking FDA Approval — The international group of exoskeleton providers with various FDA or CE certifications is growing and currently includes: Ekso in the US; Cyberdyne in the EU and Japan; ExoAtlet from Russia; and Israel’s ReWalk.

The O'Reilly Radar Podcast: Balaji Srinivasan on the bigger picture of bitcoin, liquid markets, and the future of regulation.
The promise of bitcoin and blockchain extends well beyond its potential disruption as a currency. In this Radar Podcast episode, Balaji Srinivasan, a general partner at Andreessen Horowitz, explains how bitcoin is an enabling technology and why it’s like the Internet, in that “bitcoin will do for value transfer what the Internet did for communication — make it programmable.” I met up with Srinivasan at our recent O’Reilly Radar Summit: Bitcoin & the Blockchain, where he was speaking — you can see his talk, and all the others from the event, in the complete video compilation now available.
The bigger picture of bitcoin
More than just a digital currency, bitcoin can serve as an instigator for new markets. Srinivasan explained the potential for everything to become a liquid market:
“Bitcoin is a platform for programmable money, programmable interchange, or anything of value. That’s very general. People have probably heard at this point about how you can use a blockchain to trade — in theory — stocks, or houses, or other kinds of things, but programmable value transfer is even bigger than just trading things which we know already exist.
“One analogy I would give is in 1988, it was not possible to find information on anything instantly. Today, most of the time it is. From your iPhone or your Android phone, you can google pretty much anything. In the same way, I think what bitcoin is going to mean, is markets in everything. That is, everything will have a price on it — everything will be a liquid market. You’ll be able to buy and sell almost anything. Where today the fixed costs of setting up such a market is too high for anything other than things that are fairly valuable, tomorrow it’ll be possible for even images or things you would not even think of normally buying and selling.”
The evolving marketplace is making new data applications and interactions possible.
Here’s a look at some options in the evolving, maturing marketplace of big data components that are making the new applications and interactions we’ve been looking at possible.
First used in social network analysis, graph theory is finding more and more homes in research and business. Machine learning systems can scale up fast with tools like Parameter Server, and the TitanDB project means developers have a robust set of tools to use.
Are graphs poised to take their place alongside relational database management systems (RDBMS), object storage, and other fundamental data building blocks? What are the new applications for such tools?
Inside the black box of algorithms: whither regulation?It’s possible for a machine to create an algorithm no human can understand. Evolutionary approaches to algorithmic optimization can result in inscrutable, yet demonstrably better, computational solutions.
If you’re a regulated bank, you need to share your algorithms with regulators. But if you’re a private trader, you’re under no such constraints. And having to explain your algorithms limits how you can generate them.
As more and more of our lives are governed by code that decides what’s best for us, replacing laws, actuarial tables, personal trainers, and personal shoppers, oversight means opening up the black box of algorithms so they can be regulated.
Years ago, Orbitz was shown to be charging web visitors who owned Apple devices more money than those visiting via other platforms, such as the PC. Only that’s not the whole story: Orbitz’s machine learning algorithms, which optimized revenue per customer, learned that the visitor’s browser was a predictor of their willingness to pay more.

Andreas Antonopoulos urges the Canadian Senate to resist the temptation to centralize bitcoin.
Editor’s note: our O’Reilly Radar Summit: Bitcoin & the Blockchain will take place on January 27, 2015, at Fort Mason in San Francisco. Andreas Antonopoulos, Vitalik Buterin, Naval Ravikant, and Bill Janeway are but a few of the confirmed speakers for the event. Learn more about the event and reserve your ticket here.
We recently announced a Radar summit on present and future applications of cryptocurrencies and blockchain technologies. In a webcast presentation one of our program chairs, Kieren James-Lubin, observed that we’re very much in the early days of these technologies. He also noted that the technologies are complex enough that most users will rely on service providers (like wallets) to securely store, transfer, and receive cryptocurrencies.
As some of these service providers reach a certain scale, they will start coming under the scrutiny of regulators. Certain tenets are likely to remain: currencies require continuous liquidity and large financial institutions need access to the lender of last resort.
There are also cultural norms that take time to change. Take the example of notaries, whose services seem amenable to being replaced by blockchain technologies. Such a wholesale change would entail adjusting rules and norms across localities, which means going up against the lobbying efforts of established incumbents.
One way to sway regulators and skeptics is to point out that the decentralized nature of the (bitcoin) blockchain can unlock innovation in financial services and other industries. Mastering Bitcoin author Andreas Antonopoulos did a masterful job highlighting this in his recent testimony before the Canadian Senate:
“Traditional models for financial payment networks and banking rely on centralized control in order to provide security. The architecture of a traditional financial network is built around a central authority, such as a clearinghouse. As a result, security and authority have to be vested in that central actor. The resulting security model looks like a series of concentric circles with very limited access to the center and increasing access as we move farther away from the center. However, even the most outermost circle cannot afford open access.
