Challenges of blockchain muddle understanding of the technology

I have read many articles and generalized argle-barg on the topic of blockchain and cryptocurrencies, and a couple things stand out: Nobody has a great definition for either, and the two are often so thoroughly conflated that most attempts at cogent definitions are pointless..

Nobody seems to agree on what a blockchain is — or isn’t — except in some loose, arm-flapping way. That lack of understanding represents one of the most significant challenges of blockchain. Cryptocurrencies are mostly understood in that “I’ll know it when I see it” way, where we agree on a vague idea without understanding the core of the idea. If you ask the average person about blockchain or cryptocurrencies, and to the extent that she is aware of either, the answer you’ll probably get is simple: bitcoin.

Conceptually, of course, the idea of a blockchain is like the idea of one of its main components: cryptography. Cryptography is understood as a monolithic thing in only the most abstracted macro sense possible, where different types of cryptography — among them symmetrical, asymmetrical or public key — are all implemented in vastly different manners.

Blockchains are the same: The bitcoin blockchain underpinning the popular currency bearing its name is not the same as the Ethereum blockchain upon which the cryptocurrency Ether sits. And this is where not having good definitions of what we’re talking about hurts the larger conversation around how this technology can add value outside of currency applications.

What are the challenges of blockchain in an evolving marketplace?

At its core, a blockchain is a distributed system of recording and storing transaction records. Think of it as a superdatabase — one where each participant maintains, calculates and updates new entries. More importantly, nodes work together to verify the information is truthful, thus providing security and a permanent audit trail.

How blockchain works

So, with that concept in mind, we can broaden our understanding of the technology. Ethereum wasn’t designed as a one-trick pony to run a monetary application like its bitcoin cousin; rather, it’s more of an application platform, using virtual tokens in the place of cash. Instead of simply trading currency, one might trade cat videos, for instance.

And if those cat videos were traded on a blockchain platform, everyone would be able to verify who first introduced a particular video into the system and each person who modified that video or reintroduced a bad copy. You could have the most distributed and verifiable cat video platform ever created. Luckily, there are many more use cases for this technology than just a cat video distribution platform.

In world of medical records — or, for argument’s sake, network configuration changes — we see a unique opportunity to improve many aspects of the use, transfer and security of those records.

What if we could guarantee the records introduced to the system are authentic? Note that I didn’t say accurate, because you can easily authenticate bad data when it’s introduced to a system. But let’s say we introduce our records, and they are accurate.

We go to a new doctor who would normally need to have paperwork from us to authorize the retrieval of those records, and transferring the records often takes longer than would be ideal. Waiting for the requesting doctor to send the forms to the records’ holder and get a response back can take significant effort. And even if the systems are the same, with easy access afforded to the requisite records, those records could have been tampered with or have errors and incomplete data.

The same thing could happen with a blockchain-based system, but there would be a distributed record of the tampering — something that would be all but impossible to hide. In this way, your records could be made available to everyone with a reason to see them, with each view, change and movement recorded in a permanent and tamper-resistant system.

There are challenges even beyond the implementation of our hypothetical configuration system on top of blockchain. Disparate systems would have to be combined into a ubiquitous and fairly homogeneous platform. There would have to be standards applied to the introduction of data in the first place: Bad data in; bad data out. But, in this case, it would potentially become a permanent fixture. There are also challenges in the blockchain implementation itself — the applications on top of it notwithstanding.

And those challenges are substantial.

Adding more nodes and records makes the ledger more complex

I have to agree that today’s applicability of the technology to networking is just not there. Where I disagree, however, is in the assertion that there is no need for it, or that it cannot, or should not, ever be applied to the problem of network management.

One of the challenges of blockchain is in its very nature: the distributed ledger. Because every endpoint has to have a copy of the entire blockchain, and that blockchain is constantly growing as more things are added, the system gets slower, taking up more space. If the same sort of system was implemented under a medical records system, you can see where it would become untenable very quickly.

Each blockchain implementation is different, but derivative, so this is a problem that is likely fixable. But it has to be accounted for in the beginning. Different implementations have already begun to solve this inherent weakness.

That brings us to another issue: Changing blockchains after the fact is not an easy task. Imagine a time where our network configuration data sits on a system in which a significant bug is found.

How does that system get patched? How does the blockchain adapt? And how do the requisite changes affect the integrity of the records’ data sitting on the system? These are difficult problems to solve, and they’re even harder to anticipate upfront. Most of the major blockchain implementations have gone through some amount of retrograde “shoulda-woulda-coulda,” and it’s likely we’ll fail to anticipate every possible problem in the initial rollout of any system.

Networking and the challenges of blockchain: Can they be overcome?

Blockchain technology, as it applies to networking, is very much a work in progress. GlobalData analyst Mike Fratto rejected blockchain technology, saying the ledger is “untested, unproven and overly complex, making it unsuitable for networking.”

While I disagree with Fratto’s assessment in a broad sense, I have to agree that today’s applicability of the technology to networking is just not there. Where I disagree, however, is in the assertion that there is no need for it, or that it cannot, or should not, ever be applied to the problem of network management.

I was prepared for the inevitable conclusion there are no viable production-ready blockchain implementations out in the wild. Had I come to that conclusion, however, I would have been almost entirely incorrect. I have talked with several large companies that are either developing or actively using blockchain technologies of one type or another — most seem to be based on the Linux Foundation’s Hyperledger platform, in close orbit with IBM. Most of the applications I was able to get information on are related to supply chain security in one way or another.

Tracking the ingredients used in a product from field to store shelf is one popular example. Securing critical manufacturing parts from creation through shipping and onto final build is another. These use cases are not from hyperbolic tech startups or boutique manufacturers; they are from large, established, blue-chip and Fortune 500 companies not given to flights of fancy in their supply chain. As these installations become more widespread, I imagine we will start to see more published case studies, leading to more installations. For now, however, a lot of these remain in the shadows, happily ensconced behind nondisclosure agreements.

The hype today may be all around the various cryptocurrencies that exist in the market, from the bitcoins and Ethers of the world to the nascent and opaque world of boutique vanity coins. The real excitement and potential lies not in the coins, however, but in the application of the underlying technology — including overcoming the challenges of blockchain — to everyday IT challenges.

HP X-360 3 in 1 convertible laptop. i5, 8Gb, 128gb SSD Windows 10

Selling my much used and well loved (read well used) HP X-360. Think of this as a BMW with 140K on the clock rather than a Ford Ka with demonstrator miles :) It has been used a lot….but never abused.
There are some cosmetic flaws and it has occasionally frozen (no blue screen) for no particular reason (but tends to be using FB). I read this might be a Win 10 bug though?
Its been a real workhorse but time to move on.
Pics to follow but the price reflects the issues above. I am willing to…

If it were broken I would sell it for parts but I used it for the last few days without problem and restored it to factory setting, again, without a single hitch. Might be because I use a wireless mouse and I had lots of peripheral drivers loaded??

Anyway, first refusal to Gazaman as he made enquiries in another thread.

Connect with NYT best-selling authors Henry Winkler, Lin Oliver, and hundreds of writers for Skype in the Classroom’s Literacy Month |

Today is World Read Aloud Day, signaling the start of Skype in the Classroom’s month-long celebration of reading, writing and storytelling. We are proud to work with LitWorld and our global publishing partners, Penguin Random House, Scholastic, Arbordale, Andersen Press, Candlewick and others to offer hundreds of free virtual visits from authors to classrooms. You can look up guest author information easily for Skype in the Classroom by checking our literacy collection.

To cap our month-long celebration this year, Microsoft is teaming up with Penguin Young Readers for a free broadcast event in which classrooms and families can meet actor, producer and author Henry Winkler, as well as his co-author, Lin Oliver. Together, they’re creators of the NYT best-selling book series, Here’s Hank, featuring the quick-witted and ingenious character, Hank Zipzer.

Henry and Lin will discuss their books and what makes every kid a hero while answering questions live on Twitter. The broadcast and live Twitter chat will on Wednesday February 28th at 9 a.m. EST and 1 p.m. EST.

Henry and Lin created their character, Hank Zipzer, based on Henry’s own real-life struggles with dyslexia. Hank is smart and resourceful, always finding ways to overcome challenges through friendships, determination, and a whole lot of humor. His story has resonated with kids around the world, providing some kinship and advice for those tougher times in school. Henry’s main message in the books, “Every one of you has greatness in you,” comes from his personal life experience. He proves that having learning challenges can’t keep you from greatness!

Teachers and their students, or parents with their children at home, are invited to register here and submit questions in advance or during the event for Henry and Lin to answer. We’ll be using the @skypeclassroom Twitter account and the #Skype2Learn hashtag to organize the conversation.

That’s not all for this celebratory month of reading and writing: Teachers around the world will also share their own Skype Collaborations related to literacy. Your class can join with others – across borders or close to home – to work on a writing project, share stories, and read aloud to one another. Cultivate World Literacy is just one example of many lessons devised by teachers.

This month we also celebrate the educators around the world who are using experiences like Skype in the Classroom and technologies like Microsoft Learning Tools to support literacy development. We will share and learn from their creativity and experience advancing the literacy skills of their students on the Microsoft Education Blog throughout the month.

One more thing: Roald Dahl’s Imaginormous Challenge has returned for 2018. Today, the search for five golden ticket winners begins. Students across the U.S. ,aged five to 12, are invited to submit 100-word stories for the chance to win prizes related to creative storytelling. Entries will be open for three months until 1st May 2018.

One golden ticket winner will see their story idea transformed into a Minecraft world, in partnership with Minecraft Education. They will be flown to Seattle with their parent or guardian and work with a team of Minecraft builders and Youtube creator Stacyplays, transforming their story idea into a playable Minecraft experience for anyone in the world to download and play.

Another golden ticket winner will be flown to Los Angeles and get to work with actor, producer, director and author Henry Winkler and his writing partner, Lin Oliver, to transform their story idea into their very own published short story. To enter, students simply submit their 100-word story idea at imaginormouschallenge.com.

We hope you’ll join us for this celebration of all the new and innovative ways children are being inspired to read and write. If you haven’t tried Skype to add inspiration and additional relevancy to your classroom’s curriculum, Literacy Month is a great time to start. With the hundreds of authors available to talk with your students and your Skype connections, you may just be witness to the next Hank Zipzer!

A full list of Penguin authors who visit classrooms virtually, for free over Skype, is available online.

OK, I’m in! How do I participate in Skype in the Classroom’s Literacy Month?

Teachers/Parents:

  • Register now, for free, to have your children/students to join NYT Best Selling Authors Henry Winkler and Lin Oliver on February 28th, as they discuss the uplifting messages from the Hank Zipzer book series, Here’s Hank.
