Blockcerts — An Open Infrastructure for Academic Credentials on the Blockchain

Article from MIT Media Lab announcing the launch of BlockCerts.

Blockcerts provides a decentralized credentialing system. The Bitcoin blockchain acts as the provider of trust, and credentials are tamper-resistant and verifiable. Blockcerts can be used in the context of academic, professional, and workforce credentialing.

This is probably the first of many blockchain academic credentialing systems, but it's released under on an open source license, so will have some advantages for users.

Where Is Current Research on Blockchain Technology? — A Systematic Review

Research which conducted a systematic mapping study with the goal of collecting all relevant research on Blockchain technology.

The objective is to understand the current research topics, challenges and future directions regarding Blockchain technology from the technical perspective.

The results show that focus in over 80% of the papers is on Bitcoin system and less than 20% deals with other Blockchain applications including e.g. smart contracts and licensing.

The majority of research is focusing on revealing and improving limitations of Blockchain from privacy and security perspectives, but many of the proposed solutions lack concrete evaluation on their effectiveness.

Many other Blockchain scalability related challenges including throughput and latency have been left unstudied.

Blockchain Just Got Much More Powerful

New tech created by Accenture and Stevens computer science professor can edit the blockchain without derailing it.

Stevens computer science professor Giuseppe Ateniese's breakthrough research innovation was to create a new type of blockchain tech that can edit the transaction chain — rewriting or removing information for legal, privacy or other reasons, and marking the change — while still preserving security and continuing the chain without complex additions required.

The hype and potential behind blockchain technologies

Recently a very influential technology analyst group released its annual Hype Cycle for Emerging Technologies. In this report you can find their perspective on where a variety of new-wave technologies are on their journey to mainstream adoption.

If you’re wondering where blockchain technologies appear on that hype cycle, I can tell you that it sits precipitously near the top of the hype cycle peak and right before the drop into the “Trough of Disillusionment”.

Don't let banks fool you, the blockchain really does have other uses

A summary from The Register of where we are at the moment with Blockchain.

"there is exciting potential for this technology, but perhaps not in the ways most people think. And ultimately, new or old technology, it will all come down to business processes, policy and regulation to define what changes and benefits we will get out of this."

"In terms of a new underlying protocol, that will also depend on consensus and adoption, and to a much greater extent than in the early days of the internet as we are today more cognisant of the enormity of the potential impact of such technologies and thus more committed to trying to get it right."

Blockchain is the most disruptive invention since the Internet itself - not just in finance

By now you are sure to have heard of Bitcoin and the blockchain technology. Even so, very few people seem to realize that the blockchain won't just kill banks, brokers and credit card companies.

It will change every transactional process you know. Simply put, blockchain eliminates the need for clearinghouse entities of any kind. And that means a revolution is coming, a fundamental sea change in the way we do business.

Beyond Badges: Why Personalized Learning Advocates Need to Care about Blockchain

Tom Vander Ark of Getting Smart has argued that “parent-managed learner profiles” will by key to both enabling and scaling personalization in education. As Tom envisions, these profiles would include all of the elements of traditional school transcripts, supplemented with richer, more nuanced, and actionable information about student learning attainment, achievement, and needs. Critical to this vision is the ability for the student transcript to both be easily portable (and under direct parent/student control) and decentralized (in that traditional education institutions should not completely control or dictate its contents).
