To achieve this, a new database layout was implemented which allocates unspent transaction outputs to a compact custom format in order to reduce the size of information required for validation work.Bitcoin Core is an MIT-licenced Qt 5 GUI application for the original.
To further optimize the performance of the system, Ultraprune was introduced in parallel with LevelDB, which deprecated the old BDB database technology.
