A weird solar blockchain thing - Rowan Energy

by @edent | , | 2 comments | Read ~254 times.

Using Blockchain to encourage green energy is not viable due to the incredible amount of energy it takes to mine transactions.Our blockchain is a POA (proof of authority) blockchain that is designed to run on ultra lower powered devices. The devices are in the home of our supporters and take only about $10 per year to power.

I blog about my solar panels - probably a bit too much! Recently, a reader asked me if I'd heard of Rowan Energy's solar payback scheme - so I took a look into it. Here's how it works: Rowan installer a "miner" next to your solar inverter (the big box that turns DC from solar…

What happens if you steal someone's Good Tweet™?

Fraud alert warning signs.

Way back in the early days of the Social Web, the writer Cory Doctorow invented Whuffie. Think of it as a way to formalise "upvotes" and "likes" on social media. Whuffie, a form of digital social reputation, replaces money and is a constantly updated rating that measures how much esteem and respect other people have…

Stop this digital ownership madness. NFTs are bullshit. And the stupid makes me angry.

Fraud alert warning signs.

(A hastily written and grumpy post.) Another day, another Blockchain Bullshit project. Alright, I got this Lady_Crypt0. The NFT (Non Fungible Tweet) is headed your way. https://t.co/JVgGFmUhrD — NFT Tweets Transfer (@tweet_nfts) February 14, 2021 Someone "claimed" one of my Tweets and added it to the Blockchain. I'm not particularly happy about that. Nor am…

Digital Scarcity is a Con

In the early days of the web, I used to go hunting for Beatles Bootlegs. I scoured forums, emailed dodgy geezers, and swapped poorly encoded RealAudio™ files on USENET. The Beatles had recently released their Anthology series, and us nerds were desperate to hear more unreleased goodies. Sure, there were rarities and out-takes, but we…

User Stories From The Blokechain

bləʊk ʧeɪn Noun: any technology which attracts clueless men User Stories are great! A simplified snippet to help you understand the problem you're facing. There are, of course, a vanishingly small number of genuine use-cases for the Blockchain. So cryptobores have to resort to ever more baroque explanations to sell their wares. I recently stumbled…

Security issues on ArtChain

A website with a popup notification.

One of the problems with the BlockChain goldrush is that it attracts a lot of people who don't necessarily have the required technical skill to safely run a service. This in turn reduces trust in the ecosystem. I'd like to discuss ArtChain.info - "Certifying Art Using the Bitcoin Blockchain" - and the some of the…

How I became Leonardo da Vinci on the Blockchain

Yesterday at the CogX conference, I sat in a room listening to companies pitch their blockchain based startups. Because I hate myself. One in particular caught my attention. On the surface it seems to solve an important economic problem - art forgery and provenance. By putting your artwork on the "BitCoin Blockchain", Verisart will ✨hand…

Decentralised Food Safety Reviews

Two dogs sat at a computer. One says "On the blockchain, nobody knows if you're an authority."

In most civilised countries, there is a central authority which inspects restaurants for hygiene and safety. Their job is, broadly, to stop people getting poisoned, falling sick, or dying. That's a pretty good feature of civilisation, I'd say. We think that most restaurant owners are probably good people - but it seems sensible to have…

Things For Which Cryptographic Signing Would Be Useful

by @edent | , , | 1 comment | Read ~381 times.

Every time someone mentions BlockChain, I have to down my drink. Those are the rules. You see, most uses of Distributed Ledger are really just a way to get people interested in cryptographic signing. There's lots of money and attention flowing to projects which have no need to publish to an energy-inefficient global database. They…

I went to an event a few weeks ago where some leading BlockChain organisations were showing off the power of Distributed Ledgers and how they will transform society. Not one of them mentioned users. There was talk of investors, stakeholders, corporations, smart-contract-backed entities. But no users. No real people who have to interact with their…
