### The Realms of the Benefits, Disadvantages, Challenges, and Opportunities of Blockchain
For example, the possibility of reducing transaction costs occurs because blockchain may solve many supply and demand matching issues. This will be made possible by the symmetry of information between consumers and suppliers [26]. In this same sense, smart contracts can significantly contribute to the governance of organizations. With blockchain, deals can become decentralized, and transactions can be executed with smart contracts and virtual currencies [27]. In other words, contracts and \begin{table}

Table 2: _Cont._payments can be executed and settled automatically according to parameters agreed upon in advance by the parties. Human action will be required only at the time of negotiations. Following the same perspective, trust and transparency among negotiating actors can lead to more efficient use of resources. Blockchain may secure information sharing while maintaining the privacy of those involved [28]. This integration improves efficiency in resources such as time, people, and others. Thus, even if the efficiency gains are short-lived, the new technology allows rethinking processes associated [29]. However, sometimes the experts were at variance with the literature. According to one expert, adopting technology will have a chance of reducing gains from some actors or eliminating them from the supply chain. The intermediaries' elimination could break the links in the supply chain by monopolizing production and excluding many people from the production process.
