DePIN Solana scanned the DePIN track again today. At present, DePIN mainly focuses on areas such as computing power, data (storage, computing), network/bandwidth, etc. Solana has become the preferred public chain for many DePIN projects, mainly due to: ① performance advantages; ② Strong ecosystem - innovative projects and new concepts emerge constantly; ③ Cost advantage. Essentially, DePIN is an effective matching of resource supply and demand through the sharing economy of resource crowdsourcing. Therefore, projects that can help improve the effective matching of scarce resource supply and demand have greater value. The development of blockchain requires DePIN, as tokenization needs to be integrated with the physical world. But for DePIN to achieve wider popularity, the problem is not on the supply side, but on how to tap into demand. Like many Web3 projects, for DePIN, relying solely on tokenization stimulation is not enough. Currently, the biggest problem with Depin is that it is an optional item, not a must-have. How to give DePIN the "must-have" attribute will be a core challenge for Depin's development.
