The Potential of the Blockchain: LinuxCon Keynote Preview

By Amanda McPherson

For the past few years I have been fascinated by the rise of Bitcoin and the technology that underpins it: the blockchain. Like Linux, the blockchain is an example of the continued march towards distributed systems and technology. Trust is a central element of these types of systems and the blockchain can enable this through its unique technology. If we have unique person-to-person trusted transactions without the need for a centralized institution all types of innovation and efficiency can be unlocked, especially for those in the developing world. Decentralized and federated systems of larger and larger parts is the way our civilization is heading and the blockchain can be a core enabler of that progression. There are many similarities between Linux and the blockchain and so I was thrilled that Greg Maxwell, one of the core Bitcoin maintainers and a long term open source and cryptogrophy developer, accepted my invitation to keynote LinuxCon this year. I recently caught up with him to talk about his speech and the potential he sees for the Blockchain. Tell us about your work at Blockstream and the potential of the blockchain in areas outside Bitcoin? I am really intrigued by many of the potential applications, especially for the developing world. Can you give us a glimpse into a future powered by distributed open technology? Bitcoin presented a solution to a previously thought to be unsolvable problem: How can machines securely come to an agreement about the state of a shared ledger without resorting to trusted third parties. The obvious first application was creating a world wide digital money that doesn’t depend on centralized authorities. But creating a…

Docker 1.8 released

By corbet The 1.8
release
of the Docker container system is out, with a number of new
features. “Docker Content Trust is a new feature in Docker Engine
1.8 that makes it possible to verify the publisher of Docker images. When a
publisher pushes an image to a remote registry, Docker signs the image with
a private key. When you later pull this image, Docker uses the publisher’s
public key to verify that the image you are about to run is exactly what
the publisher created, has not been tampered with, and is up to
date.
