At present, the traditional Internet system adopts a multi-centralized system. For example, Facebook and Twitter are the mainstream social softwares in the overseas market, while Microblock and WeChat are dominating the the domestic market. Users, who are playing the most important roles in traditional social ecology, have made great contributions in attention and creativity value. However, they are not in the benefit distribution circle and have nothing to do with ecological governance and decision-making. Of course, due to the centralized storage of user information, information leakage will also occur from time to time.

However, the Internet social products in the era of Web 3.0 have been greatly improved in terms of privacy, security, freedom, convenience and user volume. With the progress of blockchain technology and the changes of application hotspots, the SocialFi encrypted social networking has gradually become a strong demand of Web 3.0. SocialFi is actually a combination of Social and Finance, which will open up a brand new way of social interaction. First of all, SocialFi combines social contact, Web3.0 and finance together and provides reward and profit for the users through marking social influence. Users embrace the benefits of creation on the platform and their creation in the platform will not be monopolized and exploited by the platform itself. Secondly, compared with the simple blockchain + social networking mode, SocialFi attaches great importance to the attributes of DeFi. Thirdly, there are various forms of mining in SocialFi, including social mining, content mining and liquidity mining, etc.

The operation of SocialFi takes content, social networking, economic system with DeFi as the core and decentralized organizational structure as the pillar. A complete ecology is gradually being constructed, presenting a unique development trend. Early in 2017, the SocialFi project began to explore its way of development. Around the year of 2017, a large number of blockchain + social networking projects have emerged in batches, and ONO, QunQun, GSC, YeeCall, NRC, SwagChain, HuobiChat and TTC Protocol have been launched one after another.

In the second half of 2021, Whale, Chiliz, Rally and other social tokens once increased significantly and BBS network, Showme, Mirror. xyz and other projects enjoyed great popularity. By the end of November 2021, Monaco Planet, a SocialFi platform, has been popular, and the socialfi project had attracted a lot of attention. At the same time, Internet giants are also making overall arrangement of the SocialFi circuit. Among them, Biance, the blockchain giant, has launched a $500 million investment plan, with SocialFi as one of its key concerning areas.

In terms of investment, since the second half of 2021, SocialFi projects including BitClout, Friends with Benefits, DeSo, Torum, Monaco Planet, BBS network and Mirror.xyz have received huge investment from well-known organizations such as Binance, Sequoia Capital and Three Arrows Capital.
We can come up with the conclusion that the ecology of SocialFi is gradually improved with the development of Web 3.0. We can also see the construction of a series of infrastructure in today's ecology such as community tools, distribution mechanism, insurance mechanism and aggregators.

SociLink is a secure distributed social system running on the blockchain, whose initial plan and final target is to make use of Web 3 0 and Social to build a federally autonomous intermediate system that will be utilized by the blockchain enthusiasts in 233 countries around the world. In the process of continuous changes and technology iterations, the SocialFi ecosystem built by SocialLink has become more unique and more oriented to Web3 0.
