Fundamentals of blockchaining

In a business network, the tracking assets and the process of recording transactions are facilitated by the shared immutable ledger called a blockchain. Assets are of two types they are tangible and intangible. The tangible assets are land, house, cash, etc. The intangible assets are copyrights, branding, properties patterns, intellectual property, etc. On a blockchain network, anything that has a value can be tracked and it can be traded.
