One of the most pertinent uses of blockchain lies in smart contracts or digitized contracts that operate over blockchain without the need for a third party. Smart contracts are legally binding, unchangeable and automatic. For instance, if two parties reach an agreement for a paid project, they can enter the information into the smart contract with certain criteria that need to be met. Once all specified conditions have been completed, payment will automatically be made. Since everything is automated from the beginning, the entire process is secure, quick and leaves no room for interpretation — an important factor in business transactions at all levels.
