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 Speech Union, that's an interesting

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/status/2031657347433603581

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 people can end up disagreeing so vehemently... vanis

by gendal 6mo ago
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 see how it works at scale. This is because the wind f

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 over-weekend runs. We were getting close to relea

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 without too much distraction and noise), but it was you who act

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 world. Mike's comment about how Corda is blockchain-l

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?) of the nuclear legacy costs for countries like the UK

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-beyond-Lessons-remarkab... When I say detai

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 a civil engineering problem into a manu

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 did a bit of manual work to figure out how to reach me? If

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 work.

by gendal 5y ago
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 then encrypting it so it can only run in an enclave

by gendal 5y ago
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 idea, therefore, is that A sends the secret to an enc

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 languages), 2) make the remote attestation

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 job of putting Hyperledger's case and I agree with him i

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 toolchains to achieve determinism) But I thought it would also be

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 degree certificate by post? Or do they send a cour

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 preventing the relevant transaction getting into a block o

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 that puts them out of reach, 2) that this transaction has bee

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 agent networks. As for visa, I wrote about it recently h

You're right - sorry. I drew the whole slide first and then subtracted pieces to support the flow of the story. It meant some parts were a bit squashed.... and you're right that, in isolation, the early diagrams look a bit conf

Excellent point. The original version of the slide had two extra boxes labelled "lender of last resort" and "open market operations"... :-) Thanks for the motivation to perhaps write a part two to this post.

Exactly. My contention is that you can perhaps regard the entire Bitcoin network (of full nodes) as providing RTGS services for the Bitcoin currency. The question, then, is: "is this sufficient"? Do we believe all Bitcoin t
