What exactly is a blockchain? Let's have a short overview of this term for those who have never heard about it or didn't understand it the first time 🙌 Blockchain is a distributed, immutable ledger that makes it easier to record transactions and track assets in a business network. A tangible asset (a house, car, cash, or land) can be intangible (intellectual property, patents, copyrights, branding). A blockchain network can track and trade almost anything of value, lowering risk and costs for everyone involved.
