A story written by reddit user jessquit made me wonder, how crazy is it to think that VISA’s world wide usage would be able to move to Bitcoin Cash? Jessquit writes: According to Visa, they process about 150M txns per pay (1700 tps).

Payments secure with dsproof

Sep 25, 2020

Several years ago I invented an exciting concept of a Double Spend Proof. To understand what it is, let’s first figure out what a double spend is. When I use Bitcoin Cash and I pay someone, I spend a coin, a coin is just a digital file and it is easy to copy.

Paying for infrastructure

Aug 9, 2020

A hot topic for some time now is the funding of infrastructure development in Bitcoin Cash. Several methods have been suggested and tried, with varying degrees of success. When it comes to the longer term health of the coin I would like to highlight an often overlooked method of funding the ongoing infrastructure development.

The story of how BCHs 2020 DAA came to be.

Aug 4, 2020

About a year ago discussions started around the Bitcoin Cash DAA (Difficulty Adjustment Algorithm). It was getting clear that there were problems, but frankly only a small number of people looked close enough to know about the malfunction at all.

The Double Spend flowchart

Jul 27, 2020

A double spend attack is where a person tries to steal from another person or merchant by creating two transactions, one that pays himself and the other that pays the merchant. The idea is that the attacker makes the merchant see the one for him and then tries to get the transaction paying him to be mined.

CPfP, on-chain usage.

Jul 14, 2020

In Bitcoin there is a concept called “Child Pays for Parent” (CPfP). It allows transactions that may be stuck to get “un-stuck” in a simple manner. (background) In the Bitcoin Cash case the usage of this method is much less needed than on a saturated chain where the queue is perpetually full.

FloweeJS; finding negative block times.

May 16, 2020

As the focus for Bitcoin Cash protocol development is shifting to the November upgrade we should look at the difficulty adjustment algorithm (DAA). The current DAA, that doesn’t work so well, is a simple filter and it has been suggested by various people that an exponential decay filter would work better.

Seeder

May 6, 2020

Last week I introduced the world to a new library called P2PNet. A C++ library that allows developers to build a wide range of Bitcoin Cash related applications. Working with a work-in-progress wallet quickly made me realize that the Bitcoin network is full of nodes that are not actually following the Bitcoin Cash chain.

Introducing a C++ lib: P2PNet

Apr 22, 2020

st couple of weeks I’ve worked on a new library for Flowee. The library is called ‘P2PNet’ and has been pushed to the project git yesterday. The purpose of this library is to provide programmers with a very simple way for their programs to become part of the network of Bitcoin Cash, speaking the peer-to-peer (P2P) protocol.

Mythbusting: Bitcoin (on its own) cannot scale.

Dec 26, 2019

This myth is very stubborn in being squashed. For years have we seen people give numbers, show results and do design improvements that clearly gives the indication that Bitcoin can scale on-chain. Mostly with bigger blocks. Yet, there is still a myth that this is impossible.

Mythbusting: We need a developer-fund

Dec 25, 2019

This myth has been going around the crypto sphere for some time. Competing coin Dash has a system where funds are continuously generated that pay for further development. They have the ‘developer fund’ built in. Most people propping up this myth are not so blatant as Dash, but the concepts are always similar that either some social pressure or maybe a forced method there will be funds routed towards development.

SPV is secure

Dec 21, 2019

There are still a lot of misconceptions out about SPV wallets, people make it seem like they are less useful than they are, and this is a shame. SPV wallets are wallets with “Simplified Payment Verification”. A term that actually shows up in the original Bitcoin whitepaper from Satoshi Nakamoto.

2019 was a good year for Flowee

Dec 20, 2019

I’ve been working in Bitcoin for quite some time now, with my first commit some 5½ years ago. After Gavin Andresen stepped down from Classic, and Bitcoin in general, I became the maintainer there. And a little over a year ago I started focusing on my own vision of what a so called “full node” should be.
