This week, I work on something that goes beyond protocol mechanics. Speed, consensus, and cryptography are necessary, but they are not enough. If ZooBC is going to be useful in…

This week I run into a problem that has nothing to do with blockchain, and everything to do with browsers. The web wallet works. It signs locally, talks to nodes,…

In the past months, while I was rebuilding ZooBC from scratch, something kept happening to me in the background: I was not just coding, I was re-learning everything at a…

This week, ZooBC leaves the lab. Up until now, everything has lived on nodes, terminals, and test networks. Powerful, but inaccessible. A blockchain only becomes real when people can use…

This week, I switch focus from the network to the human. Consensus, performance, and security matter, but none of it helps if people cannot safely manage their keys. Private key…

These past two weeks, my mindset shifts slightly. Up to now, the focus has been correctness, performance, and behavior under normal conditions. This phase is about assuming things will go…

These past two weeks, I stop trusting myself. That sounds dramatic, but it is exactly the right mindset at this stage. A blockchain implementation cannot be mostly correct. It must…

These past two weeks, ZooBC stops being about correctness and starts being about reality. Getting things right is only the first step. Once the system behaves correctly, the next question…

This week, I stop flying blind, or with a foggy view only thanks trough the glasses of SQL queries. A blockchain without visibility is a black box, and black boxes…

These past two weeks, I spend most of my time on the part of ZooBC that matters more than anything else. Consensus. Everything else can be rewritten, optimized, or replaced.…
