Bitcoin brings the open source to money.
The technique behind bitcoin is developed by Satoshi Nakamoto. The most important about cryptographic money is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part.
The technique behind bitcoin is called blockchain. The blockchain is a decentralised database divided between a network of computers. The blockchain is the foundation for a new way of organizing society.
If this is one of the first encounters with Bitcoin I recommend you to watch the documentary Bitcoin: The End of Money as We Know It.
