init.cpp Bitcoin Core startup source code
This is our first exploration of Bitcoin-specific code in this series of articles.
Until now we've looked at how the Qt system was set up to run the GUI and Bitcoin services in...
Bitcoin Blockchain to MySQL Insertion Tool
Crypto.BI Toolbox comes with a raw .dat block file to MySQL insertion tool called blocks_inserter. To use it, first you’ll need to generate the MySQL schema on your local server by importing scripts/sql/mysql/cryptobitoolbox_bitcoin.sql into your MySQL server. Then you will need to configure Toolbox with the appropriate username, password, host and database so that Toolbox […]
Bitcoin Toolbox Home
Crypto.BI Toolbox is a set of tools for local blockchain exploration. It uses data from the raw Bitcoin block data files and does not require a network connection, API’s and other 3rd party data sources. It’s built of a combination of C++ libraries, Python integration and many other planned components that aim to make blockchain […]
256 Bit Integer commented uint256.cpp from Bitcoin Core source code
If you’ve developed systems in C or C++ before then you’re probably familiar with the stdint.h (cstdint for C++) typedefs. Since there’a lot of variation between platforms, stdint.h standardizes integer type names in an intuitive way. A uint8_t is an 8-bit unsigned integer and a uint64_t is a 64 bit unsigned integer. What you won’t […]
optional.h a pre-C++17 optional type in the Bitcoin source code
optional.h is a stub that’ll likely get removed from Bitcoin Core at a future date when C++ 17 gets formally adopted for the entire project. By reading the Bitcoin Core sources you can see that lots of sections could use C++ 17 idioms. Let’s keep in mind though that Bitcoin Core is high security software […]

Source code is the machine logic implemented in a programming language. Fortunately, the most popular cryptocurrencies are open source, allowing us to study their source code.
Bitcoin is the world's first viable decentralized cryptocurrency. It was released on January 2009 by Satoshi Nakamoto.
Go Programming Language
The Go Programming Language, or Golang, was developed at Google and first released to the public in 2007. Many respected names were behind the language, such as Ken Thompson and Rob Pike, both of whom were involved in the early development of C and UNIX at Bell Labs.
Haskell is a purely functional programming language which generates very secure and elegant programs. Haskell is used in the implementation of the Cardano ADA cryptocurrency.
Java is an object-oriented programming language introduced in the mid 1990's. Borrowing its syntax from C and C++, its main objective was to simplify memory management and make C++ programming faster, more fun and secure. Today it's one of the most widely adopted programming languages.
