According to Golden Finance, Vitalik published an article titled "We should talk less about public goods funding and more about open source funding", which pointed out that the word "public products" has a century of history. In digital ecosystems, especially in decentralized digital ecosystems, public products are extremely important: In fact, there are good reasons to show that the average goods people may want to produce are public products. Open source software, academic research on encryption and blockchain protocols, open educational resources and more are public products. Vitalik believes that it is also the best practice to talk less about public product funding and open source funding. Open source should not mean "building anything is equally noble as long as it is open source"; it should be about building and open source what is most valuable to humanity. However, it is well known that distinguishing which projects are worthy of support and which projects are not worthy of support is the main task of the public product financing mechanism.
