The traditional social structure allows people with authority to monopolize information, and history has proven that these people will bend the rules to their benefit. Even if people claim that their system is fair, it still lacks transparency, proving that everything is still conceived upon pillars of sand called trust. In contrast to this, blockchain provides a decentralized system that does not require a single point of failure and makes a transparent and trustless system. This is possible because blockchain is a system that allows anyone to view, prove, and host with a highly fault-tolerant consensus mechanism.
