Search Optimizatio is the next generation of decentralized Web3.0 application technology development infrastructure, aiming to provide an easy-to-use blockchain technology development platform for Web3.0 users and developers. Search Optimization (Search Optimizatio) will focus on user privacy, and the goal is to effectively reduce the difficulty of technology development when Internet developers apply blockchain technology and technical personnel in major public chain ecosystems cross-chain to other public chain technology research and development. Using the technology of storing data in a decentralized system, $SO is derived to realize the application. The huge number of users will make the value of $SO immeasurable. In addition, search optimization establishes a common middle layer between decentralized applications and various blockchains, helping them interact efficiently and creating a complete Web3.0 infrastructure.
