I have been battling an internal war. The question: In which format should data be stored in? Twenty years ago, the question was fairly simple. Much was moving from proprietary storage systems to relational database management systems. That was a…
I am very much a C++ person. I warmed up to the language as it was warring with C for programmers and popularity. Although I used neither for my “day job” ex/cept on rare occasions, I jumped at opportunities to…
I have been building out some algorithms that rely on detecting “consolidation”. Chartists know what that looks like, but the term by itself is extremely vague to a quant. What to do? I have often thought about the method used…
This is part 3 of a series on improving performance. Click here for part 1, and here for part 2. Now that the basics are done, it is time to start thinking more about testing. Some may say “but what…
This is part two of my order book exercise. To start at the beginning, click here. The initial commit of my order book uses a std::map as a collection of bids and asks. That works, but it has a problem.…
As an academic exercise, I wanted to take on building a matching engine in C++. The purpose here is to iterate through the process of measuring and improving performance. I imagine the initial requirements as naive, with later iterations including…
The Bitshares Core code distinguishes between assets in the following manner: CORE – A base asset. Only one exists on the chain, and is created within the Genesis Block. On the BitShares mainnet, this is BTS. On the BitShares testnet,…
BitShares has many controls around market pegged assets (MPAs) and their ability to be “shorted into existence.” Some of those fields have long names and difficult to sort out abbreviations. I am hoping to prepare this document to help sort…
Do you want your own token? Who doesn’t? Here is how you can create your own token on the BitShares blockchain. This is called a “User Issued Asset” or UIA. For this tutorial, I will be using the BitShares public…
The BitShares-Core project uses Boost Test features to exercise the product. When starting the test, here are some interesting command line options: –run_test=module/test This will run a specific test. We organize them into modules, that usually match the filename for…
