The application of blockchain is actually very limited, don't build anymore! Since the development of blockchain technology, its application scenarios seem to have reached the ceiling. Looking at the existing mainstream applications, there are actually only a few categories: -Centralized exchange (should be a decentralized exchange): Uniswap、SushiSwap…… -Lending platform: Aave、Compound、MakerDAO…… -Decentralized stablecoin: Dai (issued by MakerDAO) -Mixed currency platform: Tornado Cash、Railgun…… -Cross chain Bridge: tBTC（Threshold Bitcoin）、RenBTC（Ren Protocol）…… -Prophecy machine: Chainlink、Tellor…… These applications basically cover the core functions of blockchain: transactions, lending, privacy protection, cross chain interoperability, and data introduction. To be honest, having these is enough! Expanding further, such as yield farming for liquidity mining, derivatives, or synthetic assets like Synthetix, actually doesn't make much sense. Why? Security issues are always a weakness. Although the decentralized nature of blockchain is attractive, it also brings vulnerability risks and complexity, and even slightly scaled applications may become targets for hackers. After 2020, fresh ideas in the blockchain field have almost dried up. The so-called 'Build' - teams that are still vigorously developing new projects are mostly not innovating, but figuring out how to make money. To put it bluntly, those who are still "working" are most likely trying to cheat or even commit fraud. So, my opinion is simple: at present, all projects claiming to be "Build" are considered fraudsters by default, unless they can provide convincing evidence to prove that they are not. The application of blockchain has come to an end, don't waste any more time and resources!
