A while back, there was some discourse on Cardano Twitter about how AI could replace the highly skilled node developers working on Cardano core or alternate nodes. While AI has been hugely transformative and accelerative, it simply isn’t at a place where it can produce a these engineers. Without expert guidance (and even with it), software produced by AI only asymptotically approaches the quality or confidence needed from a blockchain node implementation. Without expert guidance to evaluate, steer, and tease apart the requirements of such a node, an AI is doomed to fail.

(Note: If you haven’t seen, I’m largely off Twitter, except to occasionally stay informed and mirror blog posts like this one to my audience.)

This post demonstrates the transaction diagram components at various levels of complexity.

On November 21st, 2025, Cardano suffered a severe degradation of service that lasted roughly 14 hours. This blog post serves as my independent record of what happened, my assessment of how serious it was, and my assessment of how the network, chain, and community responded to it.

This justification serves as a batch justification for my votes on the 39 treasury withdrawals in 2025 administered by Intersect.

For the last 6 months or so, Sundae Labs has been working together with Input Output and Well-Typed to study and refine the design of Ouroboros Leios, a proposed upgrade to the Cardano consensus mechanism. Leios is a protocol whose security is already well understood, but having confidence in the security of a protocol is a long way from knowing exactly how to build, deploy, and parameterize it.

Hi all.

A few days ago, the Catalyst Fund 10 results were published, and this has caused quite a stir within the Cardano community.

On January 23rd, the Cardano blockchain underwent its first real-world test of large-scale resilience. Approximately 60% of all Cardano nodes crashed and rebooted. As part of the triage team, I was asked to write a blog post providing a community-centric post-mortem analysis of the incident, the quick response from IOG and the community, and the robustness of the Cardano network.

Today, a stablecoin called Djed launched on Cardano¹. Djed is based on research that IOG published on safe algorithmic stablecoins. Stablecoins are an important part of the DeFi ecosystem, because they’re designed to maintain a stable price relative to USD (or another underlying asset). How it does this can be confusing, so this post will explain how Djed works, and allow you to explore the protocol before you try it for real.
