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...
ELI5 PSBT – Partially Signed Bitcoin Transactions
Trustless operation is one of the key concepts behind cryptocurrencies. The idea is that you should not have to personally meet, or trust your peers, in order to perform successful transactions. Experienced crypto users may take this concept for granted, but come to think of it – every real world transaction before cryptocurrencies came about […]
Building Bitcoin Toolbox MySQL Blockchain Inserter from source
Here you’ll find instructions on how to build Bitcoin Toolbox from source code. Build Requirements Bitcoin Core >= 0.18.99 Boost Libraries >= 1.71.0 CMake >= 3.5 g++ >= 9.2 Boost Libraries Build or download a binary distribution of Boost Libraries. Take note of the root Boost directory (where boost/ is found). We’ll call this directory […]
Bitcoin Blockchain to MySQL ETL Tool
Crypto.BI Toolbox comes with an ETL tool that allows you to extract data from the block DAT files and import the blockchain into MySQL. If you got the blocks directory configuration set up correctly, then you can run the ETL tool. Go to the Crypto.BI Toolbox installation directory and run: $ ./toolbox/db/blocks_to_sql > <output_file.sql> This […]
Bitcoin Blockchain SQL Schema for MySQL
This SQL schema was created for Crypto.BI Toolbox. The same, or similar, SQL schema can be used by anyone exploring Bitcoin with the help of a MySQL RDBMS. Although we didn’t test this SQL with other RDBMS’, it should be fully compatible with MariaDB and any other MySQL-derived system. How the data is inserted/retrieved to/from […]

Cardano is a 3rd generation cryptocurrency which is developed based on scientific methods, peer review and aims for formal verification and on-chain governance and compliance.
cardano-node is a full node implementation of the Cardano ADA Ouroboros protocol. It is written in the Haskell programming language and aims to obtain formal verification of correctness in the future.
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.
Linux is the world's most popular *NIX-like open source operating system. Most cryptocurrency full nodes run on Linux servers.

C++ programming language - used to implement Bitcoin Core, as well as most first generation cryptocurrencies, high performance Bitcoin miners and other critical software.
In computer programming, a Uint256 is a 256 bit unsigned integer type. Since most mainstream computers can hold at most 64 to 128 bit numbers natively, 256 bit integers such as those used in Bitcoin must be especially crafted. Uint256 is the integer type used for Bitcoin and other cryptocurrencies' private and public keys.
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.
