In the previous post we added to the Open Badges’ DNA its first genes extracted from the blockchain. We obtained the following results:
Everything can be represented as a Badge — everything is relationship;
A BadgeChain is made of chained badges (not yet a blockchain);
A BadgeChain is a distributed database: badges are stored all over the Internet.
New objects can grow organically from the aggregation of badges in the BadgeChain — e.g. ePortfolios.
There are two points we have not addressed yet:
How is the BadgeChain practically stored?
How can we trust the content of the BadgeChain?
The trustworthy BadgeChain
Can we check whether the components of the BadgeChain, a badge, is authentic (the issuer is the issuer, the earner is the earner, etc.) simply by looking at it, just as we would do to check whether a banknote is counterfeit? The answer is yes, and the means to do it is named cryptography. Here are the conditions to create badges that resist effective counterfeiting:
Every participant in the network uses one or more public /private key pair;
The public keys are used as the identities of the participants in the network.
The private keysare used to encrypt information that can then be deciphered using the matching public keys.
Reciprocally, the private keys are used to decipher any information encrypted by the matching public keys
The picture below illustrates the process when Alice creates a badge containing the information that will be used to verify whether it is authentic or not.
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.
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?
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.
In a previous post, I explored the potential deleterious consequences of equating Open Badges to credentials. My point was not to critique credentials, nor the use of Open Badges as credentials (there is nothing wrong with that), but to build on Carla Casilli’s call:
“we still need badges to flourish in the non-regimented space of not-credential.”
To understand the urgency of a response to that call, we need a reality check and to pay proper attention to the actual state of Open Badges. If we had to infer a definition based on current Open Badge practice and technology, we would have to write:
Open Badges: an institution-centric credentialing technology designed to support formal recognition of learning.
The Open Badge Infrastructure gives institutions the power to act, i.e. create and deliver badges (‘spray’) and learners the right to collect and display badges (‘pray’). While learners have to carry a backpack to prove their credentials, issuers do not!
In this post, we will move the discussion from the critique of equating Open Badges to credentials to exploring the potential of badges as signs of recognition, setting the foundations for making informal recognition as valuable and potent as formal recognition. This can be achieved by moving the centre of gravity of Open Badges from institutions to individuals and self-organised communities.
Formal and informal recognition
While there are many initiatives towards the recognition of prior learning and recognition of prior experience, what is usually meant is formal recognition of prior learning as in accreditation of prior learning. Although there is abundant literature on the [formal] recognition of informal learning (including almost the whole literature about Open Badges!), there is almost none on the informal recognition of informal learning, the “non-regimented space of not-credentials” evoked by Carla Casilli.
To frame the question of Open Badges as signs of recognition I start by eliciting two key dimensions:
Two weeks ago, during the Badge Alliance weekly Community Call (link) when Nate Otto presented the outcomes of the Badge Alliance Board Meeting, one of the slides (c.f. below) triggered a discussion on whether Open Badges are “just about credentialing”:
Are Open Badges just about credentialing?
Earlier in April, Carla Casilli posted her reflections on “Open badges + credentials: the value of the not-credential” (link):
“Right now, we still need badges to flourish in the non-regimented space of not-credentials—a world of value that has yet to be fully realized or appreciated—where the sliding scale of social and cultural currency changes depending on context.”
Doug Belshaw responded to Carla stating: “ I just can’t see a situation where a badge wouldn’t also count as a credential — even if that wasn’t the original intention” (link). Doug further adds:
“What badges don’t have to be, even if they’re wholly contained within the ‘credential’ circle, is traditional. They can recognise all kinds of knowledge, skills, and behaviours — as well as all kinds of things we haven’t even thought of yet!”
While defending that badges are credentials Doug Belshaw claims that “badges don’t have to be […] traditional,” yet it is precisely because badges tend to be “traditional” that Carla Casilli writes “we still need badges to flourish in the non-regimented space of not-credentials.” Could there be a connection between thinking of Open Badges as credentials and the reason why they are not being more used in the “non-regimented space”?
“While Open Badges could become an authentic rejuvenating medicine, many are only interested in an educational BOTOX® for a cheap facelift.”
With the growing interest of institutions of formal education in Open Badges, I am afraid that we are more likely to witness the transformation of Open Badges technology and practices to fit the needs of formal education for conformance rather than the other way around. While Open Badges could become an authentic rejuvenating medicine, many are only interested in an educational BOTOX® for a cheap facelift — Don Presant detailed one such example in Problems with “Badges for Food”.
My claim is that the vocabulary we use to describe Open Badges and the processes they support can make the difference between authentic transformation and masquerade — and avoid BOTOX®mishaps!Continue reading →
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”?
“All digital technology is ideological. All education technology is ideological”
“Technologies, particularly the new computer and communications technologies of the twentieth century onward, help reinforce dominant ideology”
One problem with the word technology is that it both refers to a “collection of techniques, skills, methods and processes” and the technical objects, the artefacts where they are embedded.
Technology is the collection of techniques, skills, methods and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation.
Ideology is a collection of doctrines or beliefs shared by members of a group. It can be described as a set of conscious and unconsciousideas which make up one’s beliefs, goals, expectations, and motivations.
For the clarity of this part of the rebuttal I will use “technical objects” to refer to artefacts and technology to refer to the “collection of techniques, skills, methods and processes.” With that being said, a blockchain is a technical object that, as any object, is subject of investigation and discourses, including ideological.
The problem with statements like “All digital technology is ideological. All education technology is ideological” is it can be applied to everything without adding an iota of understanding. Remove “digital” and you have “all technology is ideological.” Then remove “technology” and you have “Everything is ideological.” Well, so what?Continue reading →
