Cryptocurrency is traded through a system called blockchain, which involves a ‘sender’ and ‘receiver’ of the transaction record, along with a ‘miner’ who verifies the transaction’s integrity. Essentially, it is a multi-party system that depends on computer hardware known as a server. Running a computer to calculate and validate transactions consumes electricity, and to participate in the blockchain network, the cryptocurrency issuer must pay a fee. This fee effectively reflects electricity costs. Since the blockchain system relies on electricity, the core of cryptocurrency ultimately comes down to energy. - Joseph’s “just my thoughts”
Vaccines have allowed people to travel worldwide. Migration and population density are benefits of vaccines. When vaccines failed to curb the epidemic, the “space” ultimately addressed the epidemic. This history is why maintaining “social distance” is essential. Hunting requires one million square meters to secure a person’s livelihood, but urbanization restricts many individuals from accessing such vast spaces. On the other hand, if agriculture can address livelihood needs with just 500 square meters, and its efficiency can increase by 2,000 times, then the perspective on the epidemic reveals insights about civilization. - Joseph’s “just my thoughts”
