From Badges to BadgeChain: Part 2

This post is the second in a series of five blog posts designed to explore, inform, and encourage public discussions about the possibilities, opportunities, and challenges arising at the intersection of Open Badges and blockchain technology. Find the first post, “The Open Badges Part” here.

A quick aside


A very brief history of blockchain

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?

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

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.
