In my experience, people smile when they hear the words Zero-Knowledge Proof . Maybe I did too, I don’t remember, that was a long time ago. But it is not uncommon to hear jibes like this “I’m an expert at Zero-Knowledge, I know nothing about it”.
In this post, I give a gentle introduction to the theme, so that you can have non-zero knowledge about ZKPs.
If you own Bitcoin, your history of transactions is public to everyone who knows your wallet address. In this post, I show how ZK-SNARKs can be used to enable confidentiality of transactions in a crypto-currency.
These are interesting times we live in. This can, of course, be a good thing (exciting new opportunities) or bad (an euphemism for hard choices and impossible problems), but at least on the technology front, I believe more in the first than the latter. There are just too many compelling technologies coming down the pipeline …
Currently at Artos, we are researching ZK SNARKs in depth. One of the tasks we’re handling is to convert a library written in Java (DIZK) to work with the same ZK SNARK scheme used by ZoKrates and libsnark, which are written in C++. Parts of this have already been detailed somewhere else in this blog. …
In the last post, I made an introduction to the concept of Zero Knowledge Proofs, and talked a bit about ZK-STARKs. Today, I’ll dive into the maths in Vitalik Buterin’s first post in a series about the subject. Vitalik does a good job of explaining them, but I feel the need to synthesise the information …
Truth in a blockchain is just one of many histories. Time-related bugs can be as non-intuitive as quantum parallel universes.
When you write a blog, and still work full-time, time is not easy to find. What strategies can you use to fight writer’s block and keep your blog alive?
It is not easy to write Ethereum contracts for the first time. If you can not find reference, material on how to start, this series will give you all you need to know.
I started the Coder’s Errand in 2018. Part of the reason I did so was that I needed change, I felt the urge to move forward in my career and explore things that were happening in the technological world outside my normal reach. But when searching for a theme, I found inspiration elsewhere. 2017 was …
