Do agents need our chains at all?

There’s a growing narrative in crypto that AI agents will be a massive catalyst for blockchain adoption. Agents will never have bank accounts, they need to pay for things, therefore they need crypto. QED, number go up.

Bitcoin Conference 2025 in Las Vegas

Earlier this month I attended my second Bitcoin Conference, held at The Venetian Resort in Las Vegas.

Inaccuracies in “Ethereum – How A Lie Became Worth Billions”

Last week, Isabella Santos released an 11 minute video entitled “Ethereum – How a Lie Became Worth Billions”, which has had a good number of views and retweets. I watched it and am sorry to say that it contains a large number of inaccuracies and bad assumptions. I made some notes in a Telegram group and it turned into an essay, which I’ve saved here from posterity and future reference.

Notes from BlockApps “The Early Days of Ethereum” Part III (Bob Summerwill guest appearance)

Earlier this week I made a guest appearance on the third episode of the “Early Days of Ethereum” series which Kieren James-Lubin , Victor Wong and James Hormuzdiar , the Co-Founders of BlockApps have been making in the past month or two. We spoke for about 80 minutes and it was a delight to reminisce about these happy days. I absolutely loved the earlier videos and wrote a long blog post with…

BlockApps “The Early Days of Ethereum” videos

Kieren James-Lubin , Victor Wong and James Hormuzdiar , the Co-Founders of BlockApps , have produced two videos in the last month or so reminiscing on the early days of Ethereum. The videos have been a delight for me to watch. While their journey overlaps with my own, I am learning some things which I did not already know. Their vantage point was slightly different to my own. Recording this…

Recovered 🙂 My first paid programming work, from my work experience at Penrhyn Quarry. Made for an open day and they gave me 50 quid after the fact. I bought a USB 3.5″ disk drive to attach to me Mac, and the disk just worked, and the emulator just worked too: Here is the Pascal source code : And a video of the game being played (though sadly with no audio - you will have to imagine that!)

Background on Ethereum client licensing

On 23rd November 2022, Alexey Sharp of the Erigon team announced that Erigon were winding down support for the Akula client which they had been developing for nearly two years. During that time there were 722 commits from 21 contributors, with the vast majority being single-handed work from Artem Vorotnikov. The Erigon team took this action in the face of another Rust client on the verge of…

BSV’s plans to freeze and move coins

There have been rumblings for years about the BSV project’s plans related to “court orders”. The Bitcoin (BSV) Association dropped a bombshell on 5th October 2022, announcing their Digital Asset Recovery Process and releasing the Blacklist Manager . This is the closest that we have seen to on-chain censorship for any blockchain, and the censorship is just the first step. The second step is…

ASIC Resistance is a myth

“ASIC resistance” is a myth. The author rejects that myth as do many other individuals within the ETC ecosystem. This position statement seeks to foster confidence that decisions around ETC mining are not being guided by an easily disprovable myth, but by the application of science, measurement and facts - not subjective personal beliefs. The Ethereum Classic project “inherited” both philosophy…
