🇺🇸 Well, that was expected — “I’ve recorded this here since it feels like the chronology of events and the smaller details are already evaporating, and this helps me wrap my head around a tiny fraction of it. If you happen to read this, don’t take this at face value (nor anything else on the web for that matter). Do your own research and correct me if you think any of the timestamps are wrong.”
📺Fox News and the real insurrection — “After Democrats said they planned to impeach Trump again, Fox opinionators echoed the risible Republican talking point that such a move would be provocative; after Twitter banned Trump, they pivoted to bash Big Tech. Yesterday morning, Jeanine Pirro compared Amazon’s decision to boot Parler, an app popular among right-wing extremists, from its web-hosting services to Kristallnacht—the night, in 1938, when Nazis in Germany killed around one hundred Jewish people and arrested tens of thousands more”
₿ Lost Passwords Lock Millionaires Out of Their Bitcoin Fortunes — “Of the existing 18.5 million Bitcoin, around 20 percent — currently worth around $140 billion — appear to be in lost or otherwise stranded wallets, according to the cryptocurrency data firm Chainalysis. Wallet Recovery Services, a business that helps find lost digital keys, said it had gotten 70 requests a day from people who wanted help recovering their riches, three times the number of a month ago.”
🕸️ Pirated Academic Database Sci-Hub Is Now on the ‘Uncensorable Web’ — “As evidenced by Sci-Hub’s own problems, the decentralized web is being built out of fears of deplatforming. As the internet’s access points are increasingly centralized in the hands of a few actors, certain applications – most recently, Twitter-alternative Parler – have faced censorship at the hands of web server providers, app stores and DNS certificate authorities.”
🏛️ Internet 3.0 and the Beginning of (Tech) History — Here technology itself will return to the forefront: if the priority for an increasing number of citizens, companies, and countries is to escape centralization, then the answer will not be competing centralized entities, but rather a return to open protocols. This is the only way to match and perhaps surpass the R&D advantages enjoyed by centralized tech companies; open technologies can be worked on collectively, and forked individually, gaining both the benefits of scale and inevitability of sovereignty and self-determination.

Decentralisation is an interesting concept, mainly because it’s such an abstract concept for people to grasp. Usually, when people talk about decentralisation, they’re either talking about politics or technology. Both, ultimately, are to do with power.
When it comes to learning, therefore, decentralised learning is all about empowering learners, which is often precisely the opposite of what we do in schools. We centralise instruction, and subject young people (and their teachers) to bells that control their time.
To my mind, decentralised learning is any attempt to empower learners to be more independent. That might involve them co-creating the curriculum, it might have something to do with the way we credential and/or recognise their learning. The important thing is that learning isn’t something that’s done to them.
3. Slippers and sandals
I’m wearing slippers right now, as I do when I’m in the house or working in my home office. I don’t think you can go past Totes Isotoner, to be honest. Comfy!
Given I live in the North East of England, my opportunities to wear sandals are restricted to holidays and a few days in summer. I had a fantastic pair of Timberland sandals back in the day, but my wife finally threw them away because they were too smelly. I’m making do now with some other ones I found in the sale on Amazon, but they’re actually slightly too big for me, which is annoying.
4. Carbon footprint of blockchain-based credentials
I’ll start with the Bitcoin Energy Consumption Index, which gives us a couple of great charts to show the scale of the problem of using blockchains based on a proof-of-work algorithm:
That’s right, the whole of the Czech Republic could be powered by the amount of energy required to run the Bitcoin network.
As you can see from the second chart, Bitcoin is a massive waste of energy versus our existing methods of payment. But what about other blockchain-based technologies, like Ethereum?
They’ve had the same problem, until recently, as Peter Fairley explains for IEEE Spectrum:
Like most cryptocurrencies, Ethereum relies on a computational competition called proof of work (PoW) . In PoW, all participants race to cryptographically secure transactions and add them to the blockchain’s globally distributed ledger. It’s a winner-takes-all contest, rewarded with newly minted cryptocoins. So the more computational firepower you have, the better your chances to profit.
Ethereum’s plan is to replace PoW with proof of stake (PoS)—an alternative mechanism for distributed consensus that was first applied to a cryptocurrency with the launch of Peercoin in 2012. Instead of millions of processors simultaneously processing the same transactions, PoS randomly picks one to do the job.
In PoS, the participants are called validators instead of miners, and the key is keeping them honest. PoS does this by requiring each validator to put up a stake—a pile of ether in Ethereum’s case—as collateral. A bigger stake earns a validator proportionately more chances at a turn, but it also means that a validator caught cheating has lots to lose.
Which brings us back to credentials. As I’ve said many times before, if you trust online banking and online shopping, then the Open Badges standard is secure enough for you. However, I can still see a use case for blockchain-based credentials, and wouldn’t necessarily rule them out — especially if they’re based on a PoS approach.
5. How educators can promote their good practices without looking like they’re bragging
This is really contextual. What counts as ‘bragging’ in one culture and within one community won’t be counted as such in another. It also depends on personality too, I guess — something we don’t really talk about as educators (other than through the lens of ‘character’).
The only advice I can give is to do these three things:
Keep showing up in the same spaces every day/week so that people know where to find you (online/offline)
Share your work without caring about recognition
Point to other people and both recognise and celebrate their contributions
Remember, the point is to make the world a better place, not to care who gets credit for making it better!
6. Why the last episode of Game of Thrones was so very bad
I’ve never even seen part of one episode, so perhaps this can help?
Do you have any questions for me to answer next time I do this?
The Opera web browser has joined Brave in allowing users to turn on ‘cryptojacking’ protection:
Bitcoins are really hot right now, but did you know that they might actually be making your computer hotter? Your CPU suddenly working at 100 percent capacity, the fan is going crazy for seemingly no reason and your battery quickly depleting might all be signs that someone is using your computer to mine for cryptocurrency.
Given the recent explosive rise in Bitcoin’s value, however, it would seem that cryptojacking is yet another thing to guard against online…
