Starting from open

Over the last five years, we have dedicated ourselves to working in the open as key players in the open badges revolution. With this series of blog posts, we continue to share our ideas, insights and explorations publicly.

A quick aside

Since we began preparing this second post a few weeks ago, a number of truly excellent blockchain posts have been written here, here, and here. Those recently published posts have made the writing journey of “the blockchain part” of From Badges to BadgeChain both exciting and tremendously humbling.

tl;dr

No matter what else you take away from this post, keep in mind that blockchain technology is still very much in its early and experimental phases. In terms of development, this is blockchain’s Cambrian period. We’re excited to be part of the Blockchain Cambrian Explosion happening right now. And while the technology can get deep, we’ve worked hard to keep it entirely readable and understandable.

A very brief history of blockchain

Nowadays every post about blockchain seems to have the fabled history of where and how blockchain came into being, and this one is no different. Aside from wanting to keep up with all the other Nakamotos, including it here helps to explain our fascination with this potentially game-changing new technology.

In 2008, the mysterious, pseudonymous Satoshi Nakamoto released a white paper describing a decentralized peer-to-peer payment transfer system based on open source software. The white paper was followed up by a reference implementation of the proposed system: Bitcoin.

The Bitcoin initiative has grown significantly and achieved much over the years, not the least of which is succeeding as a testing ground for blockchain technology. Two current examples in the education space making use of the powerful Bitcoin blockchain include MIT (issuing digital certificates) and the Holberton School (who partnered with Bitproof to deliver academic certificates).

As we think about blockchain let us not underestimate the huge amount of work that has gone before: it is impressive and profound. We can talk about blockchain technology today because of Bitcoin. Thanks to this rather seminal connection, it’s exceedingly difficult to talk about blockchain without talking about Bitcoin. Still, the gauntlet has been thrown and we’re giving it a go. Therefore, if you are searching for deep information about Bitcoin, these aren’t the droids you’re looking for. (Instead, feel free to go here and here and here and here and here.)

What is blockchain?

In the simplest possible terms, blockchain technology builds a continuous time-based ledger. A bit more detailed definition: blockchain technology builds a continuous list of records or transactions that result in a time-based ledger. Even further defined: blockchain technology uses peers to build, encrypt, and host a continuous list of records or transactions that result in a time-based ledger (or blockchain). The result: a list of records that build upon each other, one after the other in a sequential fashion.

The peer-based distributed and decentralized database is key. The database achieves its distributed-ness through hosting: all blockchain participants host the ledger in its entirety. Together the ledger and the distributed and decentralized database create powerful opportunities for direct peer-to-peer sharing of things like content, money, contracts, etc. Blockchain eliminates the need for a central authority: because each block must be unique and relative to the previous block, transactions can’t be duplicated. Also, once a block is written to the chain, it is permanent and cannot be changed.

Even with this limited definition, it’s quite obvious that Nakamoto’s apparently simple system possesses great conceptual strength and technological rigor. Imagine the possibilities of this sort of system and you can begin to see why we’re at the beginning of an explosion of interest and development.

Blockchain technology: a growing revolution

Innovations that go beyond what might be called the traditional Bitcoin blockchain are already underway. Two such projects include Ethereum and Multichain. Ethereum custom built their blockchain as a way to decentralize processing of smart contracts (tiny programs that can do things like modify data or perform decision-making tasks). Multichain’s open source solution aims to address issues of privacy and openness by providing the capability for the creation of private blockchains.

While financial transactions have been the dominant historical reference point for discussions of blockchain, new use cases for the ledger are arising, e.g., identity management, and storage for government data, legal, and business records. Its seemingly endless potential has convinced us that further exploration, especially with regards to open badges, is warranted.

What’s next

This intentionally brief synopsis of the birth and technological structure of blockchain provides meaningful context for what we’ll be covering in upcoming posts. With each post we continue to provide the rationale for our ongoing interest in BadgeChain. Our next post will dive into how the two protean tools, open badges and blockchain, might work together.

About technical objects, technology and ideology — Rebuttal of @hackeducation on blockchains (Part…

April 19th, 2016 | Serge Ravet

Part 1

In the third post, The Ideology of the Blockchain (for Education), Audrey Watters makes some sweeping statements:

“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.

From Wikipedia:

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 unconscious ideas 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?

The relationships between individuals, technical objects, technology and ideology are more complex and less univocal than implied by the initial statements. For example, for a philosopher like Jaques Ellul, regarding technology, instead of it being subservient to humanity, “human beings have to adapt to it, and accept total change.” For Ellul, it is the technology itself with its own impetus which is dehumanising:

“Not even the moral conversion of the technicians could make a difference. At best, they would cease to be good technicians. In the end, technique has only one principle, efficient ordering”

For Ellul, not only there is no need to make any reference to ideology to explain the negative impact of technology, but even the application of what we could call a “progressive ideology” could only result in technicians loosing their professionalism!

In an interview William Gibson (who coined “Cyberspace”) develops a reflection similar to that of Ellul:

“Technology invariably trumps ideology. And I am inclined to think that history increasingly suggests that human social change is more directly driven by technology than by ideology. I think we develop ideologies in an attempt to cope with technologies and that in fact we’ve been doing that all along. Technology is knowing how to grow, harvest and store cereals without which you can’t really do a city. Technology is knowing how to build efficient sewage infrastructure without which you can’t build a slightly larger city. So I think of technologies as the drivers and ideologies as an attempt to steer.”

From these two distant authors in time, space and culture, technologies, i.e. “the collection of techniques, skills, methods and processes used in the production of goods or services” have a life of their own.

Another important philosopher in relation to the dynamics of technologies is Gilbert Simondon who, as Wikipedia recalls is “a major source of inspiration for Gilles Deleuze and Bernard Stiegler.” Simondon’s theory of individual and collective individuation, states that the individual subject is considered as an effect of individuation, rather than as a cause. Thus the individual atom is replaced by the neverending process of individuation creating simultaneously both the individual and the collective. For Simondon, this process does not only apply to humans but also to technical objects, his main object of study — c.f. “Du mode d’existence des objets techniques”.His philosophy is at the opposite to that of Jacques Ellul as he sees in our understandingof the genesis of technical objects a means for dis-alienating our relationship with them.

Following Simondon, one possible reading of the emergence of the blockchain, as technical objects, could follow that given earlier to the Open Badges as the outcome of the individuation process of the ePortfolios (source). While the blockchain is first and foremost a database, what makes this database different from all the preceding databases is that it is autonomous (in fact, ubiquitous) and capable to interact with its environment as an individual autonomous subject. Although it is still a matter of discussion, this autonomy seems even reinforced with the possibility to include “smart contracts” the “methods [used] for restricting the transactions performed in a database” (source).

Now that we have established that blockchains are just a new form of database we should have the right to question the explanatory value of a category like the “ideology of blockchains” (sic). If there is such a think then there must be an “ ideology of databases” and may be a “MySQL ideology.” Was MySQL the product of an ideology?

I would be also very curious to know whether there is an “ideological” difference whether it is stored in a solid state disk, a hard drive or static ROM (Read Only Memory) or a live RAM (Random Access Memory). Is it where we should find the DNA of “Silicon Valley ideology” (sic)?

The next rebuttal will explore into more detail why the following sweeping statement does not provide more explanatory information that a mere tautology:

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