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 […]
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 […]
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 […]
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 […]
