GIN team proposed GEA Protocol(GIN Ecosystem Apps Protocol) in new whitepaper recently, which allow developers to build large decentralized distribute services on GIN platform, such as data mining, machine learning/AI training, oracles, decentralized VPNs, self-perpetuating workloads. I think decentralized VPNs is the best choose as the first GIN Ecosystem App, GIN platform has 8000+ nodes as infrastructure now.
VPN has HUGE demand in China. Internet users living in China need VPN access to Google, Twitter, Youtube and so many blocked websites by government. Not for privacy, but for free. According to analysis, 10 million Chinese users use VPN to access foreign websites. There are two major ways to use VPN: buy a VPN service or rent a VPS to build a proxy server. The most popular proxy service is Shadowsocks and ShadowsocksR, call for short, SS and SSR. Some websites offer dozens of SS nodes as proxy service, $3/month for 2 devices. A website called bandwagonhost rents a VPS server with built-in SS and SSR service. Users can directly modify the parameters of the SS server on the web management page.
Almost all crypto gamer in China use VPN every day, because all major exchanges are blocked by government too, like binance, bitmex or cryptoia, estimated number of cryptoer is 200,000 in recent bear market. If GIN platform offer VPN service, a group of community users in China who can help promote. The below picture shows a GIN community has 300+ people. And a Chinese exchange name qbtc.com listed GIN last year, people can buy GIN in there.
Finally, as a reference, Horizen($ZEN) is working on decentralized VPN network : HORIZEN VPN. I believe the GIN team has the ability to achieve it faster and better.
