Blockchain, the key technology behind Bitcoin, is a new network that helps decentralize trade, and allows for more peer-to-peer transactions. WIRED challenged political scientist and blockchain researcher Bettina Warburg to explain blockchain technology to 5 different people; a child, a teen, a college student, a grad student, and an expert.

This is a useful video as much for thinking about how we share ideas as it is for understanding the blockchain.

Bookmarked The Reputation Game by Ian Leslie (New Statesman)
Today, everyone’s second self is encoded in contrails of data: pictures, ratings, clicks, tweets, searches and purchases. Corporations and governments rake over this information and fix us in it: we are subjected to the scrutiny applied to celebrities but without the fame or the free stuff. In one possible future, everyone will be ranked like hotels on TripAdvisor. In one possible present, in fact: the Chinese government is implementing a scheme that will give each of its 1.4 billion citizens a score for trustworthiness, with the stated aim of building a culture of “sincerity”.
Ian Leslie looks into the question of reputation through the review of two books: Reputation: What It Is and Why It Matters by Gloria Origgi and The Reputation Game: The Art of Changing How People See You by David Waller and Rupert Younger. It is an interesting read, especially in light of everything about Harvey Weinstein and the media men list.
Bret Victor argues that digital art needs to break with coding to create expressions that go beyond code and language. This is a fascinating presentation. I have postulated before of the idea of technology splitting music into its parts allowing users to not only listen, but also engage. This is something that Bjork explored with Biophilia.

Tom Woodward has captured a number of quotes from the presentation.

Liked After Method by Jeremy Tromley (
If methods compose reality, then we should select our methods based on what kind of reality we would like to see composed. This smacks a little of the extreme epistemological view that we can create whatever reality we want simply by imagining it to be so, but tied to the concept of the hinterland there are two significant differences. First of all, we have to start from where we are – the reality that is already composed – which provides the materials (literally and metaphorically) from which we can compose a new reality. And, second, composing a new reality will take work.

Replied to The path to Twitter is paved with … by IaninSheffield (Marginal Notes)
Can you remember the route by which you came to use Twitter to support your professional learning?
Ian, your post (and visual) raised many questions. I think my own experience of Twitter was somewhat multi-pronged. There was quite a bit of inadvertent nudging, during a course on thinking, while I also had a few friends on it. I have documented a part of my story here, as well as created a short video documenting it:

I really wonder if it is ever one thing, rather than an assemblage of parts. This has me thinking about blogging as well and how the take up of Twitter might compare with the early days of educational blogging? Would there be similarities? Do these things change? Would someone starting out on their path now be different to yourself starting out in 2009? How does it differ from a wider discussion of connected education? Always so many questions.
