Before we started the first session of BinnaDevLab Cohorts, I knew one thing with certainty: If we opened with the word "blockchain," we'd lose half of the room. Not because the topic is hard. Because the word carries baggage. Crypto speculation. N...

Building Evidence Systems That Know What They Cannot Prove When we started building verifiable Knowledge in MyZubster, hashing seemed like the easy part. Take some data. Canonicalize it. Hash it. Optionally anchor the digest somewhere external. Done....

From Blockchain Hashes to Evidence Graphs: What We Learned Building Verifiable Knowledge When we started experimenting with verifiable knowledge in MyZubster, the first implementation looked simple: 1. Take a Knowledge Card. 2. Hash something that id...

We Turned a Real Knowledge Transfer Into Verifiable Evidence on Base Sepolia Today we completed an experiment inside MyZubster that connects real human collaboration, GitHub history, cryptographic commitments, and blockchain verification. The goal ...

Designing a Non-Custodial Multichain Wallet Hub for a Web3 Marketplace Building a marketplace that supports cryptocurrency payments creates an architectural decision very early: Who controls the keys? While developing the open-source MyZubster ec...

MyZubster Development Update: From Open-Source Code to a Verifiable Ecosystem Over the last few weeks, MyZubster has been evolving quickly. But the most important change isn't a new UI, another AI model, or another repository. It's architectural. ...

Building MyZubster in Public: The Part Nobody Sees When people see a technology project online, they usually see the final layer: the website. The application. The screenshots. The AI. The repository. But there is another side of development t...

Blockchain for Developers: A Practical Introduction If you have spent any time around tech Twitter, YouTube, or dev conferences in the last few years, you have heard the word "blockchain" thrown around a lot. Sometimes it is tied to cryptocurrency ...
