Decoding bitcoin and the blockchain

Introducing Bitcoin & the Blockchain: An O’Reilly Radar Summit

When the creators of bitcoin solved the “double spend” problem in a decentralized manner, they introduced techniques that have implications far beyond digital currency. Our newly announced one-day event — Bitcoin & the Blockchain: An O’Reilly Radar Summit — is in line with our tradition of highlighting applications of developments in computer science. Financial services have long relied on centralized solutions, so in many ways, products from this sector have become canonical examples of the developments we plan to cover over the next few months. But many problems that require an intermediary are being reexamined with techniques developed for bitcoin.

How do you get multiple parties in a transaction to trust each other without an intermediary? In the case of a digital currency like bitcoin, decentralization means reaching consensus over an insecure network. As Mastering Bitcoin author Andreas Antonopoulos noted in an earlier post, several innovations lie at the heart of what makes bitcoin disruptive:

“Bitcoin is a combination of several innovations, arranged in a novel way: a peer-to-peer network, a proof-of-work algorithm, a distributed timestamped accounting ledger, and an elliptic-curve cryptography and key infrastructure. Each of these parts is novel on its own, but the combination and specific arrangement was revolutionary for its time and is beginning to show up in more innovations outside bitcoin itself.”

Bitcoin’s road to democratization lies in decentralization

Conrad Barski on the bitcoin and blockchain landscape and how the technology will evolve over the next 10 years.

Conrad Barski, a medical doctor, a cartoonist, programmer, and author of Land of Lisp, has been experimenting with bitcoin since 2011. In a recent interview, Barski talked about the bitcoin and blockchain landscape and noted the potential of decentralization:

“We’re heading into a world where things are becoming more decentralized. Most people already appreciate that because we all know about things like Airbnb and Uber. Of course, there’s kind of a paradox there because we think of Airbnb and Uber as being decentralized, but of course they’re these very centralized companies that run things…I think 10 years from now we’re going to see that these types of semi-decentralized companies are going to be replaced by fully decentralized companies, where the company itself just runs in an automated way on some kind of cryptocurrency. No one knows what cryptocurrency that will be, but there are folks from Ripple, from Counterparty, from Ethereum all trying to build an infrastructure that essentially let’s you run a company that isn’t controlled by any individual person. I think that’s really in the long term the most exciting part about bitcoin.”

What about bitcoin as a currency? In the short term, it’s an open question, said Barski, but he predicted an expansion similar to what we’ve seen with BitTorrent:
