Blockchain created the new type of Internet, enabling digital information to be distributed but not copied. Originally designed for digital currency, the technology can now be used for other things. Blockchain is a database that provides encrypted transaction tracking. This technology, as the name suggests, is built with a chained model and can be followed at the same time. Blockchain technology enables operation without being connected to a center. Thus, transactions can be carried out directly between the buyer and the seller in a secure manner.
Crypto currencies are an internet-based exchange tool that uses encryption functions to execute financial transactions. Crypto currencies use blockchain technology to gain decentralization, transparency and invariance. The most important feature of a crypto currency is that it is not controlled by any central authority: the decentralized nature of the block chain makes the crypto currencies theoretically immune to government control and intervention methods.
