It's called `v1` in our protocol, and it's based on the Equi-X algorithm developed for this purpose. See the document on [`Proof of Work for onion service introduction`](../hspow-spec/index.md). This defense is configured by an operator using the `HiddenServicePoW` configuration options. Additionally, it requires both the client and the onion service to be compiled with the `pow` module (`--enable-gpl` mode) available. Current versions of the Tor Browser do include `pow` support. diff --git a/spec/hspow-spec/index.md b/spec/hspow-spec/index.md index d728781..aea9c46 100644 --- a/spec/hspow-spec/index.md +++ b/spec/hspow-spec/index.md @@ -1,10 +1,10 @@ -``` -Filename: 327-pow-over-intro.txt -Title: A First Take at PoW Over Introduction Circuits -Author: George Kadianakis, Mike Perry, David Goulet, tevador -Created: 2 April 2020 -Status: Closed +# Proof of Work for onion service introduction + +The overall denial-of-service prevention strategies in Tor are described in the [Denial-of-service prevention mechanisms in Tor](../dos-spec/index.md) document.
