However, experiments are being conducted to utilize it as the basis for smart contracts. From a functional perspective, blockchain consists of three layers. (1) The first layer records irreversible history and serves as a source of trust. (2) The second layer implements business protocols and enables smart contracts. (3) The third layer automatically enforces rules and forms the basis of social contracts. This lecture gives an overview of the three-tiered model of the blockchain economy. Concurrently, an overview of the history behind the emergence of blockchain also will be outlined. Upon considering those points, it will be argued that the use of blockchain as a means of establishing a trust foundation is in line with the intentions of the pioneers who attempted to develop autonomous organizations in the early days. • • Send Feedback: • https://forms.office.com/r/3YBs4GgxDz • Follow us on Twitter: @Ieice_trans
