#What is blockchain?
Blockchain is a decentralized database that is shared and synchronized among the nodes of a computer network and operates without the need for a central authority. Once stored on the blockchain, a digital asset becomes virtually immutable, irreplaceable, irrevocable and available for validation at any time of the day.
The transfer of data over the blockchain network is called a transaction. A file that contains data related to a transaction is called a transaction file.
The transaction file is what we verify by validating the blockchain. It is presented in the form of a PNG file.
An innovative approach to the development of simple and reliable blockchain algorithms is provided by digital chip card technology, or DCCT for short.
DCCT Network is an easy-to-use blockchain system with up to three devices connected to a common peer-to-peer (P2P) computer network. Compared to other blockchain systems that may involve multiple nodes in the chain, DCCT Network is a more innovative, productive, transparent and cost-effective solution. See more...
