Malfix is a proposed consensus change in Bitcoin Cash designed to address transaction malleability. It’s a fairly controversial proposal, in part because it would be the most invasive hardfork BCH has done to date, but also because people just don’t believe it’s needed. In this article I will present a new use case for Malfix that has not been considered before … giving BCH full Ethereum-style sma...
The central BSV talking point is that BSV is the original Bitcoin and that BTC and BCH are airdropped coins. This post will put this fallacy to rest. The following is a list of consensus rules enforced by Bitcoin SV that differ from the original Bitcoin. It should be noted that these are consensus rules which are only a subset of the broader protocol. There are numerous other changes to the protoc...

I really hate to have to pull a Giacomo here. Giacomo, of course, is the infamous Bitcoin Maximalist who declared that "Everyone who disagrees with me is either stupid or malicious!" I certainly don't believe that. I'm sure there are plenty of thoughtful people who disagree with me for honest reasons. Unfortunately, there are very few of them in the BSV community. Allow me to share a tweet of mine...

In my previous article I described the math behind Schnorr signatures as they are implemented in Bitcoin Cash. Peter Rizun responded with the following: I'd love to see a follow-up article in a similar style to explain signature aggregation :) So here it is. Signature aggregation is actually quite simple. Remember we have a key pair with private key x and public key P. And the signatu...

On May 15th of this year Bitcoin Cash will be activating a hardfork which introduces Schnorr signatures. This post is intended to be a very high level overview of the math behind Schnorr signatures (or at least the BCH variant) for people who may not understand elliptic curve cryptography. We'll start with the basics. Generating a key pair In Bitcoin we use a curve with the equation: y² = ...
