The blockchain trilemma is a theory proposed by Vitalik, which refers to the inability of blockchain networks to simultaneously achieve security, decentralization, and scalability. Ethereum, of course, has been working towards a breakthrough in this trilemma. The healthcare system's trilemma is a very real reality: it's impossible to simultaneously achieve low prices, high quality, and high efficiency. For example, many people in Hong Kong complain about the slow service times of Hong Kong's public hospitals (wait times of several years), the high costs of Hong Kong's private hospitals (outpatient fees of over 1,500 yuan), and the poor quality of doctors in Shenzhen. Both blockchain and hospitals will likely ultimately present a diverse landscape, with no perfect choice. Differentiating themselves from different perspectives of the trilemma allows users to choose products based on their needs.
