  1. Hi, I am the author of this article. on The Promise of Blockchain Is a World Without Middlemen (hbr.org) · · Score: 1

    There's a few other things which are worth taking a look at on the topic at http://internetofagreements.co... - the HBR piece is short, and this is not a topic that is particularly easy to compress.

    There are two things in particular that didn't come across well. Firstly, we expect this to be a five to ten year process. We're well aware how much there is to do, and how far this all has to come. We don't dream you can just digitize a body of law through natural language processing and then have an AI make legal rulings any time soon. But narrow areas - product labeling comes to mind - might be high value and tractable quite soon. And Internet of Agreements blockchain. Blockchain is a *how*, but IoA is a *why*.

    Second thing is that IoA's intention is to get people with various pieces of this picture into direct contact with each other, with a rough sense of the goal state in a decade or so, to start building the bits that are currently financially possible to do real engineering on. As time passes, more and more of the vision should become manageable, and things will pick up speed and come together.

    Hope that helps.

    I should start this with a disclaimer: I'm the founder of the Hexayurt Project, a Free Hardware building system aimed at refugees and in widespread use at Burning Man. It's those silver pod things (http://hexayurt.com)

    I think Wikihouse is exciting technically, but it's *incredibly* expensive to build - something like 7000 EUR of CNC cutting time for a single room. The parametric design aspects of the project are great, however, and I can see a future in which the components are mass produced at reasonable price and then assembled according to plans generated from the parametric design software. But without some kind of standardization, this kind of production is going to remain incurably expensive and therefore just another architectural demo. It's not a technology until costs are estimated. This has happened before: Architecture For Humanity's Open Architecture Network (http://openarchitecturenetwork.org/) rapidly filled with impractical technology demonstrators and student projects - 10000+ designs, but how many practically buildable?

    Actually getting buildings that people can build is hard. Architects are trained to think about custom work, one-offs and impressing other architects. Mass producing housing at a price people can afford (hello, Mortage Crisis, goodbye Mortgage Crisis) requires a radical rethink of how we do construction: modularity, prefabrication, standardization - all the same things we did for every other technology we wanted to be cheap, easy and reliable.

    It's often said that home building is the last truly-madly-deeply inefficient global industry. Imagine if they built cars by having people come to your garage to hand-assemble them! Whether the radical change is mass manufacture of entire houses Buckminster Fuller style, interchangable modular components (structural insualted panels) or something like 3D printing with insulated concrete, we can't keep buliding houses by hand in a world where everything else is efficiently mass produced with near-zero defects and not distort the shape of our societies.

    Hexayurts are dirt cheap and designed for modular mass manufacture. But they look weird. Such is life :-)

    The US military is working very hard on robots to assist in the kind of house-to-house combat they have been involved in during Iraq and Afghanistan. In that kind of conflict, there are a lot of casualties and that puts massive pressure on the politicians back home. The pressure is delayed, but very real.

    However, once they get robots which can assist in that kind of conflict, it completely unbalances the US Constitution by essentially removing the Second Amendment: effective combat robots are equivalent to gun control. I think that has some very serious implications.

    I ran a $2000 Kickstarter to fund a book called The Future We Deserve. The project was to collect 100 essays about the future from 100 people, and then write an analysis which drew out common threads and told a story about the future. The material that came in was so strong, individualistic and subtle that it was simply impossible, after a year of trying off-and-on to make an analysis so we simply accepted that the original task didn't make sense in the face of such strong material, and published it as-is.

    In the long run, there are softer vectors to attack than social networking.

But the paydirt is still VISA and tax records and face recognition tied to passport databases. I bet social network data, when you get right down to it, is just a nice-to-have compared to the passport biometrics database combined with pen registers etc. for communications.

    You might find http://guptaoption.com/cheapid interesting from this perspective: it's a proposed biometric ID card standard which blinds governments to the biometrics of their population except under special circumstances, and enforces this arrangement with strong cryptography.

    May those who help most win so they say.

    I made three entries - the hexayurt, the infrastructure package, and the low cost medical care.

    The Hexayurt
    The hexayurt is a reasonably well tested next generation disaster relief shelter built on free/open source principles and industrial supply chains. It comes from work done at the Rocky Mountain Institute. The basic idea is to take 12 standard 4âx8â industrial panels, cut six in half diagonally and fasten them into a cone (see the site for pictures) and use six whole panels for the walls, giving a durable shelter of 166 square feet, big enough for 5 people at UN standards. These shelters will survive 80 mph winds easily.

    The emphasis on using standard industrial materials is the key. Nobody can afford to carry extensive stocks of emergency housing for disasters in the developing world, which often displace millions of people. Airfreighting tents is expensive and inefficient, and tents are lousy shelter for long term use, which is all-too-frequently how they are deployed. The Hexayurt idea is that industrial cities near regular disaster zones (Bangaladesh, strife-torn areas of Africa, the hurricane belt) take their existing industrial infrastructure and add a few simple new skills so that before or after a disaster they can mass produce a simple, long-life shelter for affected populations. This is a step towards disaster relief self-sufficiency at a regional level, so that these areas begin to be able to cope without being so reliant on patchy and poorly-funded international relief effots.

    The Hexayurt concept has been tested by US DOD, and is an integral part of the STAR-TIDES program. American Red Cross and Netherlands Red Cross both think it is a great idea and have supported its development, and AMURT is considering the system. All of this has been done by a persistent self-funded open source development effort.

    http://hexayurt.com/

    The Hexayurt Infrastructure Package
    The hexayurt is a free/open disaster relief shelter which has its own entry. However, a shelter alone is not enough to really help people after a disaster. If you have 100,000 perfectly good shelters in a field, the next problem you face is water and sanitation: without some deployed solution, people will get sick and die.

    There are lots of appropriate technology solutions to sanitation, cooking without wasting wood or generating toxic smoke, purifying water to drink. All of them are under-funded, under-tested, and under-adopted. Millions to tens of millions die every year because this âoeappropriate technology infrastructureâ is not being properly funded, and the result is needless loss of life.

    The key is to understand that credible candidate technologies exist to provide all the same basic essential services that people enjoy in the developed world on a budget of maybe $200. Furthermore, the services can be provided house-by-house. For example, rainwater is collected on your roof, then purified using a biosand filter to give you safe drinking water, rather than having a water purification factory down the road and pipes. These systems are basic, and some need work, but some combination of SODIS, solar water pasteurization, thermophilic composting toilets, sulabh toilets, solar cookers, rocket stoves, gasification stoves, biosand filters, microsolar, microwind and microhydro will provide all the basic essential services of life in nearly any climate anywhere in the world. What hasnâ(TM)t been done is a global systematic program of testing each of these individual technologies in each region of the world, making local adaptations, cleaning up and publishing the designs, making training videos, running educational courses, and looking for chances to integrated, combine and synthesize systems into whole packages which are proven to provide all essential services in the field. This is our proposal.

    I have a partial solution to this problem.

    http://guptaoption.com/4.SIAB-ISA.php

    It's a proposal - done on a DoD grant - for using strong cryptography and division of powers to separate the biometric database from the identity database, so that all the metadata about a DNA sample - name, for example - is encrypted in a way which requires court orders to retrieve and - *critically* - stored by a separate agency so that it requires three separate groups to work together to bind a name to a DNA sample.

    * the DNA database must run the sample
    * the Court must agree to decrypt the name information when it is presented
    * the Identity database must agree to provide the encrypted data to the court

    This approach gives excellent security to the individual, and acknowledges the simple reality that we can't make DNA analysis and other biometric technologies go away. We have to use other technologies to counterbalance them (strong crypto) rather than hoping to turn back the clock.

It enforces that standard by moving the Big Database to an international level, but encrypting the metadata attached to each record - including fields like name - in a way which means the people with access to the database can't *do* anything with it, because there is no information about *people* in the database (like names,) only information about their physical bodies. Data stripped of metadata is largely worthless, and to unstrip an item needs a court decrypt from a national government.

    From http://guptaoption.com/4.SIAB-ISA.php

    This paper shows how we can manage large scale biometrics databases and increase the amount of privacy we have from government snooping while still having a secure society.

    The basic crux of this paper is that you can separate the biometrics database, which simply identifies your physical body, and isn't necessarily any more intrusive than Flickr or any other online photo sharing site, and the reputation database, which stores things like your credit rating, any criminal record, and the suspicions of various government agencies about your intentions.

    So when you do something like rent a car, you give them a token which has your face on it. They match your face to the token, and say "ok, this token is valid." But the token doesn't have your name, or your SSN, or anything else on it: it's totally sterile. But if you steal the car, they take the token to court, as well as the proof you gave it to them, and the court uses the token to get your name, SSN and other details.

    If all that FBI or other government biometrics database stored was tokens, and it required a court order to go from a match in the biometrics database to a name and street address, I think we'd have a fair balance between civil liberties and security. A database of pictures of faces or fingerprints is not the intrusive part: it's the connecting of your face or your fingerprint to your background that is the intrusion, and we can separate the two databases and require a court order (and a crypto key) to reconnect them.
