Multisig & Escrow: Building Trust Mechanisms
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…
Gateway – Bridging Web to Blockchain
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,…
Blockchain Zoo Academy Is Live, and I’m Teaching It
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…
Web Wallet: Decentralized in the Browser
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…
HD Wallets: Keys to the Kingdom
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…
Security Hardening: Protecting the Network
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…
Testing and Validation: Ensuring Reliability
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…
Performance Optimization: Speed Matters
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…
Network Monitor: Eyes on the Chain
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…
Proof of Participation: Consensus Refined
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.…
