Blockchain is often touted as a world-changing technology and in many ways, it is. However, it isn’t necessarily the cure-all panacea for the world’s problems that many evangelists would have you believe.

Here’s a breakdown of some of the issues with blockchain that anyone thinking of using it should understand. Starting with perhaps the biggest…

Blockchain has an environmental cost

At least, the way it is being used today, it does. Blockchain relies on encryption to provide its security as well as establish consensus over a distributed network. This essentially means that, in order to “prove” that a user has permission to write to the chain, complex algorithms must be run, which in turn require large amounts of computing power. Of course, this comes at a cost. Taking the most widely known and used blockchain as an example – Bitcoin – last year it was claimed that the computing power required to keep the network running consumes as much energy as was used by 159 of the world’s nations.

Yes, Bitcoin’s blockchain is a hugely valuable network – with a current market capacity at the time of writing of over $170 billion – so sophisticated and computationally intense security is essential. Smaller scale blockchains – such as those that an organization may deploy internally to securely monitor and record business activity – would consume a fraction of that. Nevertheless, it’s an important consideration and the environmental implications as well as the energy costs can’t be ignored.

Microsoft is out to prove blockchain naysayers wrong. In an effort to show the potential of the technology beyond its applications in cryptocurrency, the Redmond giant has announced plans to use blockchain tech as the foundation for storing and processing digital identity data.

Following a collaboration with the Decentralized Identity Foundation (DIF), Microsoft has revealed its plans to rely on blockchain technology to solve some of the challenges we face when managing our identities and personal data digitally, such as improving privacy and security across the physical and digital world.

“We believe it is essential for individuals to own and control all elements of their digital identity,” the company said in a blog post. “Rather than grant broad consent to countless apps and services, and have their identity data spread across numerous providers, individuals need a secure, encrypted digital hub where they can store their identity data and easily control access to it.”

To this end, the company is developing an off-chain solution – akin to the Lightning Network – that will allow it to process massive volumes of ID data without congesting the blockchain network.

This is a long (136 page PDF) and detailed report on blockchains in education. The authors work slowly and deliberately in their pursuit of accuracy and clarity, which results in a presentation that will be easily understood by most readers. There is a wealth of examples in the document describing use cases, scenarious and pilot projects, and companies involved in the space. The study is a result of a literature serach, desk reserach and interviews. The recommendations display a knowledge of both education policy and blockchain technology. I have no objections to any of the conclusions and recommendations, and would indeed underline some, for example, this: "Only ‘fully-open’ blockchain implementations can reach the real goals and promise of blockchain in education. By this, we mean solutions whose fundamental components include: a) recipient ownership; b) vendor independence and c) decentralised verification." It's still early days; there's a call to bring experts in the space together to create the necessary agreements, and this should probably happen sooner rather than later. The publication is a Science for Policy report by the Joint Research Centre (JRC), the European Commission’s science and knowledge service.

Puede decirse que al menos son tres las grandes soluciones educativas que se estarán desarrollando en el 2020, a saber, I) el servicio como finalidad de la educación; II) la atención-seguimiento; y III) la seguridad.

Self-sovereign identiy explained

This concept is called self-sovereign identity. Self-sovereign identity starts with the notion that we all are the makers of our own identity, online and off. Because they do not rely on any centralized authority, self-sovereign identity systems are decentralized, mirroring the way identity works in real life.

Offline, our interactions flexibly support the use of attributes and credentials from numerous third parties, all presented by the very person they’re about, typically by taking those credentials out of a wallet or purse and presenting them to someone else to verify. For example, take a driver’s license. States issue it as a credential that you’re authorized to drive. But, it’s useful for a lot more. When you show up at a bar and the bartender wants proof you’re over 21, you show them your driver’s license.

 

How blockchain can solve the identity dilemma

Self-sovereign identity systems use blockchains – distributed ledgers – so that decentralized identifiers can be looked up without involving a central directory. Blockchains don’t solve the identity problem by themselves, but they do provide a missing link that allows things we’ve known about cryptography for decades to suddenly be used. That allows people to prove things about themselves using decentralized, verifiable credentials just as they do offline.
