Ten Bitcoins had been magically transferred between Satoshi and cryptography legend Hal Finney.

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 […]
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 […]
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 […]
