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 […]

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 […]

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 […]
