Cheers. No doubt there's additional nuance I've missed but I'm fairly certain he's directionally correct. And, if he is, we face some dire consequences as a nation. Re the Free Spe…

He explains on his website where he gets his data from. He gets it from The Low Carbon Contracts Company... y'know: the firm who is the actual counterparty to the CFDs and so shoul…

The amount wind farms in the UK have contributed back over the last ten years is a rounding error compared to how much they have received. It's not even close: https://x.com/7Kiwi/…

It's a good question. To be honest, I'm still trying to get my head around how the UK electricity market works. Its complexity is definitely a big part of why so many reasonable pe…

Yes - the wholesale price of electricity can sometimes be very low (or negative), particularly when there is a lot of wind. And some tariffs pass that on to consumers. But I don't …

Not a "hard" bug but a useful lesson in any case. I worked on a set of stress tests for a major middleware product and came into the office on a Monday morning to check the 72-hour…

No need to layer on the flattery... I was hand-waver in chief (and like to think I did a good job in bringing people with us and creating the space for you and the team to work wit…

Hi everybody... Richard Brown, CTO of R3, the firm behind Corda, here. As Mike says, we're somewhat unusual in that there are many live, successful Corda deployments around the wor…

Are there any MSR designs that require NO reprocessing (whether online, batch or other)? I'd love to find actual data but, anecdotally, it seems like a large amount (vast majority?…

There's a great (and insanely detailed) book on the rise and fall of Symbian by a guy who was there for most, if not all, of the journey: https://www.amazon.co.uk/Smartphones-beyon…

None of the above. AFAIK, 'modular' here is shorthand for '(mostly) assembled on site from modules made in factories'. The idea is that if you can transform nuclear build-out from …

I received one of these emails but, interestingly, whilst the email was about my personal blog, the email was sent to my work address, which is not listed on my blog. Implying they…

Just checked... yeah... you can arrange so that an encrypted enclave can only run on a specific machine through careful use of SGX primitives. So I think your idea would probably w…

That's helpful - thanks. We don't presently support it in Conclave but SGX (which we use) does, I believe, support the idea of, in effect, packaging up a secret in a program and th…

I may not be fully understanding your scenario but it sounds like A needs to prove to B that it knows a secret but doesn't want to actually reveal/send the secret to B? And the ide…

My team has built Conclave that might be interesting. https://docs.conclave.net . The idea is 1) make it possible to write enclaves in high level languages (we've started with JVM …

Hi there - Richard Brown, CTO of R3 here. We support and maintain Corda, an open source permissioned blockchain (that is not currently part of Hyperledger). Brian has done a good j…

This piece is written in terms of blockchain platforms (where determinism of execution is important - and why some platforms hence implemented entirely new VMs and associated toolc…

Argghhh! This is EXTREMELY embarrassing... and you're not the first to point it out. I've just corrected the post. Thanks :) Quick question: do I need to return my mathematics degr…

My understanding is that the worst two things that can happen are: 1) an attacker prevents a holder of bitcoins on a sidechain from reclaiming them on the bitcoin network (e.g. by …

The actor wanting to reanimate the coins on the Bitcoin network provides a proof to the Bitcoin network that 1) the coins on the sidechain have been moved to a particular address t…

I don't know enough about Visa's design to comment authoritatively - but my working assumption is payments from issuing to acquiring banks in-country are done net and through visa …

Remember that many (most?) recipients of international remittances don't have bank accounts or access to payment cards. Hence why Western Union et al have to maintain extensive age…

Hi there, Probably the best in-depth book on this topic I've read is this one. I'd highly recommend it. http://www.amazon.co.uk/Payment-Systems-Macmillan-Financial-... (Disclosure:…

Well, I certainly hope nobody tries to build a system off the back of that blogpost! But I think there is a lot to be said for helping people build useful mental models. My experie…
