Decentralized last mile communication using mobile mesh networks
Globally decentralized protocols like Bittorrent, Bitcoin and Tor provide users a remarkable level of censorship resistance, privacy and communication freedom. But highly centralized local communication networks can block, throttle and log users of these protocols and work with governments and private firms to surveil and harass users. Centralized communication networks historically tend toward rent-seeking behavior, do a poor job at serving last-mile communities, and are fragile during natural and manmade disasters. This talk will review decentralized alternatives for local communication and demonstrate a new open source solution called TxTenna for sending offline Bitcoin transactions over a mobile mesh network.
But there’s a catch: what about the faithful ‘execution’ of a contract? Doesn’t that require trust as well? What good is an agreement, after all, if the text is there but people don’t respect it, and don’t follow through on their obligations? Which brings us back to the crucial matter of how Buterin managed to piss off so many people.
The great cryptocurrency heist.
Blockchain enthusiasts crave a world without bankers, lawyers or fat-cat executives. There’s just one problem: trust.

The Disruption Experience this Friday in Singapore is a blockchain event with a difference. With apologies to the Buick commercial, this is not your grandfather’s conference…
I know a few things about blockchain conferences. I produced and hosted the first Bitcoin Event in New York. My organization develops cryptocurrency standards and practices. We help banks and governments create policy and services. And as public speaker for a standards organization, I have delivered keynote presentations at conferences and Expos in Dubai, Gujarat India, Montreal and Tampa, New York and Boston.
Should we trust technology experts? We live in times of incredible innovations and impressive complexity. The last 30 years of technological development overturned our society, and the next 30 will likely reshape the foundations of what it means to be human. Machines have been the wealth engines of our industrial modernity, while data control and artificial intelligence will structure the power battlefields of this century.
It’s not hard then to understand why technologists, computer scientists, engineers, tech-entrepreneurs, IT experts, data analysts, etc — dress the status of champions in our age. They are shipping us into the wonders of Web 3.0, Industry 4.0, 5G communications, the blockchain transition, the G (eneticengineering). R (obotics). AI. N (anotechnologies) Revolution…and another thousand of cryptic acronyms forbidden to ordinary mortals.
We are flooded with tech-narratives. Let’s start by playing with our imaginations. What does naturally come to your mind if I say:

The virtual currency markets have been through booms and busts before — and recovered to boom again. But this bust could have a more lasting impact on the technology’s adoption because of the sheer number of ordinary people who invested in digital tokens over the last year, and who are likely to associate cryptocurrencies with financial ruin for a very long time.
The number of people who bought virtual currencies more than doubled last winter. For people who got in late, the bust has been disastrous.
Blockchain is used both by NASA and startups hoping to democratize space.
Analysis.
