From #blockchain to #BadgeChain (2) – the chained badge

In the previous post, we looked at the relationship between trust, Open Badges and blockchains. To paraphrase George Bernard Shaw, one could say: Open Badges and blockchains are two technologies separated by a common idea [trust].

To explore how Open Badges and blockchains could merge into a new technical object, my reasoning will pass through several stages. We will start with a BadgeChain that does not make any reference to the blockchain technology, then, step by step, we will describe the mutation of this initial object through the incorporation of new genes into its DNA — hoping that we will not have created a chimera!

BadgeChain take one: everything is a badge

To create something that looks like a BadgeChain, we need to link badges together; there are multiple ways this can be achieved:

  • Indirectly: badges are “connected” through each individual issuer and earner. The issuer is a kind of “connector” between all the badges issued (and their earners), the earner is a kind of “connector” between all the badges received (and their issuers). Badges can also be connected through the alignment metadata, a list of objects describing educational standards — a property of the version 1.5 of the standard that has not been widely exploited.
  • Directly: badges are literally linked to other badges. For example, an endorsement badge could use the address of the badge being endorsed as the identification for the earner of that badge.

From #blockchain to #BadgeChain – Introduction

While not initially coined to describe a technical object, but rather a team of Open Badge enthusiasts willing to exploit the benefits of blockchains, BadgeChain is also a word that might be used in the future to describe a new technical object resulting from the merger of blockchains and Open Badges.

When we started the BadgeChain group, the initial idea was to explore how blockchains could contribute towards improving the Open Badge technology and experience. There are a number of limitations to what one can do with Open Badges today that blockchains seem to be able to outsmart. Our initial reflection looked at the application of blockchain ideas to Open Badges. What has not yet been explored is the application of Open Badge ideas to blockchains: what could we do to blockchains if they used what we know about Open Badges?

About Trust

Both Open Badges and blockchains are related to trust but they do it in almost opposite ways. As I have written many times, Open Badges are trust statements that could be combined to create chains and networks of trust. The information on how the members of the network trust each other can be used as the basis to establish trustworthy transactions — if 32 Open Badge experts trust Slava’s expertise on badges as well as 53 clients, I’m inclined to trust Slava to work with me on my next project.

Blockchains on the other hand are a means to establish trustworthy transactions even if those engaged in transactions do not trust each other. The trustworthiness of the transactions is not a property depending on the participants, their behaviour or the data they provide but on an algorithm controlling the trustworthiness of the next blocks added to the chain. The blockchain technology was designed to eliminate the human factor from making the decision on whether a transaction is trustworthy or not.

BadgeChain vs. blockchain

NB: many articles on the Web describe blockchains as trustless. What is meant is that trustworthy transactions are possible without the involvement of any trusted authority (a bank, a notary or a registrar) and despite the fact that the parties involved do not trust each other. Trust is fully embedded in the blockchain infrastructure and does not need human intervention.

About technical objects, technology and ideology – Rebuttal of @hackeducation on blockchains (Part 3) #BadgeChain

Audrey Watters recently published a series of posts in the hope “of writing a clear explanation […] of what blockchain is”: The Blockchain in Education: Questions, The Blockchain for Education: An Introduction, and The Ideology of the Blockchain (for Education)

Part 1 challenged the author’s understanding of “trust” and the use of non sequitur, part 2 challenged the author’s understanding of the complexity of the relationship between technical objects, technology and ideology and the use of non-refutable statements (like the one quoted below). This part will challenge further the understanding of the author and her capacity to construct well structured arguments.

To elicit Audrey Watters’ sense of argumentation, let’s take the following statement:

Technologies, particularly the new computer and communications technologies of the twentieth century onward, help reinforce dominant ideology

While this might sound like a profound insight to the casual reader, the problem is that it fails the most elementary falsification test — being able to refute its contents. For that we suggest the following questions:

  • What technologies have not reinforced the “dominant ideology”?
  • Did computer and communications technologies only profit the “dominant ideology”?
