早前7站有人发过如何解决墙内Tor用户过少导致的隐匿性较低(特征太明显)问题? ，里面提到过 Snowflake。
我刚才顺手打开了 Tor Blog，看到6月8号的消息。
Snowflake moving to stable in Tor Browser 10.5
We're excited to announce that Snowflake will be shipped as one of the default bridge options with stable versions of Tor Browser later this month.
What is Snowflake?
Snowflake is a pluggable transport that uses a combination of domain fronting and peer-to-peer WebRTC connections between clients and volunteers to circumvent Internet censorship. Snowflake, which is the spiritual successor to flashproxy, aims to lower the barrier for running anti-censorship proxies, resulting in a large pool of proxies for users to connect to. Instead of requiring a server with consistent up-time, Snowflake proxies run as an addon or extension in your browser. These proxies can move locations as users connect to different networks, providing a moving target that is more difficult to block. We currently have about 8 thousand available Snowflake proxies each day. When a user connects to Snowflake in order to circumvent censorship, they are matched with a currently available proxy. If this proxy "melts," or disappears, the user will be seamlessly matched with a new proxy.
Snowflake currently uses domain fronting for the initial connection to match users with Snowflake proxies, and to allow each peer to exchange the connection information necessary for WebRTC. This channel is highly censorship resistant, and used only for the initial bootstrapping of the connection. As such, it requires much lower bandwidth and shorter connections than existing domain fronting pluggable transports like meek, making it a more scalable alternative.
For more technical details on how Snowflake is designed, see our documentation, the source code, and the Snowflake technical report.
文中还有 Snowflake 用户使用调查报告
Snowflake users by given country, including the number of additional participants who responded by region instead
243名确认的 Snowflake 用户自愿提供了他们的位置，其中最受欢迎的五个地点是美国（46）、俄罗斯（26）、印度（16）、德国（13）和中国大陆（9）。
243 confirmed Snowflake users volunteered their location, with the five most popular locations being the United States (46), Russia (26), India (16), Germany (13) and Mainland China (9). However, it must be noted that anglophone locations and those with fewer instances of censorship may be over-represented due to the nature of the study.
