ELI5: Blockchains explained in simple terms
A blockchain is a database formed by a sequence of entries called (you guessed it) blocks. Blockchains have a special characteristic by which any attempt to modify one of its entries would modify the entire chain. It is, therefore, an immutable data structure, which stores blocks in chronological order of insertion. This makes blockchain a […]
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 […]
Commented noui.cpp source code – Terminal interface to Bitcoin Core
We began our exploration of the Bitcoin Core source code from the Qt graphical user interface on down. We saw how the Qt signals and slots mechanism was used to handle signals from the underlying Bitcoin Core subsystems. Now we’ll take a look at the noui header and source to see how the user interface […]
Commented consensus/merkle.cpp Merkle root on Bitcoin Core Source Code
In this article we take a look at one of the most important components of block validation and overall blockchain integrity: the Merkle Root derivation process. While it’s one of the most critical components in all of Bitcoin Core, its concept and implementation are very simple and straightforward. The consensus/merkle.h header consists solely of 3 […]
