In a consortium blockchain, the consensus process is controlled by a pre-selected group – a group of corporations, for example. The right to read the blockchain and submit transactions to it may be public or restricted to participants. Consortium blockchains are considered to be “permissioned blockchains” and are best suited for use in business.
Semi-private blockchains are run by a single company that grants access to any user who satisfies pre-established criteria. Although not truly decentralized, this type of permissioned blockchain is appealing for business-to-business use cases and government applications.
Private blockchains are controlled by a single organization that determines who can read it, submit transactions to it, and participate in the consensus process. Since they are 100% centralized, private blockchains are useful as sandbox environments, but not for actual production.
Anyone can read a public blockchain, send transactions to it, or participate in the consensus process. They are considered to be “permissionless.” Every transaction is public, and users can remain anonymous. Bitcoin and Ethereum are prominent examples of public blockchains.
On Blockchain, Money and Empathy: EdSurge Talks Trends and 2018 Predictions
EdSurge’s CEO, Betsy Corcoran, argued that 2017 was a year when educators and schools were trying to take control of their technology choices “We have said from the time we started writing the newsletters that not every piece of technology will work for every student, or for every school or every classroom,” she said. “It’s all about asking the right questions to figure out if there is a piece of technology that will support learning goals. What we’re starting to really see across schools, districts and teachers, people really owning those questions. They’re saying, ‘What do I want to do with my classroom? With my kids? And what are the technologies that will support me?’”
Another discussion participant asked whether colleges and universities are starting to accept cryptocurrencies like Bitcoin, or experimenting with the blockchain technology that drives those systems. Johnson said most of the hype around unversities’ blockchain experiments has centered on storing and managing credentials.

Blockchain technology has the potential to enhance the role played by libraries within their communities, however, there are many questions yet to be answered about how specifically blockchain technology might be used and how much value it would add to library services and the communities they serve. Ideas from within the information profession are needed as we formulate recommendations for the profession.
The San José State University School of Information (iSchool) received an IMLS grant to investigate ways that blockchain technology can be used by libraries as a community anchor to partner with other organizations and to support city/community goals. Some suggestions for blockchain applications in libraries include building an enhanced metadata center, protecting Digital First Sale rights, supporting community-based collections, facilitating partnerships across organizations, and more.
The year-long project will provide three opportunities for a national dialog among technical experts in libraries, blockchain technology, and urban planning and members of the information professions to discuss ways that blockchain technology can advance library services to support city/community goals.
- The project website and blog includes information and resources about blockchain technology, potential uses of blockchain technology by libraries, and project updates along with a blog to foster open dialog. Seehttps://ischoolblogs.sjsu.edu/blockchains/
- The National Forum scheduled for August 6, 2018 in San Jose, CA will be comprised of 20-30 technical experts in libraries, blockchain technology, and urban planning to identify and discuss key opportunities for libraries to serve as community anchors using blockchain technology.
- The Library 2.018 conference, Blockchain Applied: Impact on the Information Profession, is designed for presentations and discussion on the uses of blockchain technology in libraries. Registration in this open online conference is free to the profession and public. Scheduled on June 7, 2018 from 12:00 – 3:00 pm PDT. The call for proposals is located on the conference website.
We are seeking nominations of individuals to represent the professional associations (e.g. LITA, PLA, ULC, CLIR, ARL) and information organizations by participating in the National Forum in San Jose, CA (August 6, 2018). Funding provided by IMLS is available to support most of the expenses (travel, lodging, meals) for the National Forum for invited participants.
Nominations (including self-nominations) are due by February 15, 2018. Nominees should be knowledgeable about blockchain technology and libraries in order to have an impact on the recommendations that will be made and discussed during the Library 2.018 conference and National Forum.
Nominations to participate in the Blockchain National Forum should be submitted by February 15 using this Google Form.

What Is Blockchain?
blockchain is a database or digital ledger. The data in the ledger is arranged in batches known as blocks, with each block storing data about a specific transaction. The blocks are linked together using cryptographic validation to form an unbroken and unbreakable chain–hence the name blockchain. As it relates to bitcoin, the blocks are monetary units, and the chain includes information about all past transactions of that monetary unit.
Importantly, the database (i.e., the series of blocks) is duplicated thousands of times across a network of computers, meaning that it has no one central repository. This not only means that the records are truly public, but also that there is no centralized version of the data for a hacker to corrupt. In order to make changes to the ledger, consensus between all members of the group must be obtained, further adding to the system’s security.
1. Blockchain for the Future of Credentialing
With today’s technologies, graduates and prospective employers must go through a tedious process to obtain student transcripts or diplomas, and this complexity is compounded when these credentials are spread across multiple institutions. Not only that, but these transcripts can take days or weeks to produce and send, and usually require a small fee be paid to the institution.LinkedLinek
This could be a key enabler to facilitate student ownership of this data and would allow them to instantly produce secure and comprehensive credentials to any institute or employer requesting them, including information about a student’s performance on standardized tests, degree requirements, extracurricular activities, and other learning activities.
Blockchain could play a major role in Competency-Based Education (CBE) programs and micro-credentialing, which are becoming ever more popular across universities and internal business training programs.
various companies are currently working on such a system of record. One of the most well-known is called “BlockCert,” which is an open standard created by MIT Media Lab and which the institute hopes will help drive the adoption of blockchain credentialing.
imagine the role that LinkedIn or a similar platform could play in the distribution of such content. Beyond verification of university records, LinkedIn could become a platform for sharing verified work history and resumes as well, making the job application process far simpler
2. Blockchain’s Financial Implications and Student debt
how could blockchain influence student finances? For starters, financial aid and grants could be tied to student success. Instead of students and universities having to send over regular progress reports on a recipient’s performance, automatic updates to a student’s digital record would ensure that benchmarks were being met–and open up new opportunities for institutions looking to offer merit-based grants.
Electronic tuition payments and money transfers could also simplify the tuition process. This is an especially appealing option for international students, as bitcoin’s interchangeable nature and lack of special fees for international transfers makes it a simpler and more cost-effective payment method.

Blockchain Credentialing: What Impact Will it Have?
Posted By Trent Batson Ph. D.
blockchain credentialing, big news since the MIT Media Lab offered an open source means of credentialing using blockchain technology (the technology behind bitcoin).
Blockchain credentialing makes verification of credentials much simpler and less time consuming, according to the articles I’ve collected below. Even IBM has entered the arena.
As with badges, we in the eportfolio world need to be aware of the trend toward blockchain credentialing. I’ve sorted through the links below so I could select those I thought would be most useful for you.

the “blockchain” technology associated with the cryptocurrency – the world’s second largest after the controversial Bitcoin – to revolutionise not only how aid organisations raise money but also to increase transparency in their financial transactions.
Blockchain – which emerged as one of the underpinnings of Bitcoin – is a shared record of transactions maintained by a network of computers. It has become a key technology because of its ability to record and keep track of assets or transactions with no need for middlemen.
With a valuation of some $88bn (£62bn), Ethereum – which launched in 2015 – has an equivalent market value to Starbucks, according to Forbes magazine

Communication can consist of two large areas:
- broadcasting information: PR, promotions, notifications etc.
- two-way communication: collecting feedback, “office hours” type of communication, backchanneling, etc.
Further communication initiated by/from principals can have different audiences
- staff: teachers, maintenance etc.
