How do group participants in a decentralized, metadata resistant, asynchronous environment come to a consensus on transcript consistency? This is a [https://code.briarproject.org/briar/briar/wikis/Fundamental-Problems](fundamental problem) when designing such systems and one that we need to solve in order to advance the discipline and build usable tools that people can rely on.
How do group participants in a decentralized, metadata resistant, asynchronous environment come to a consensus on transcript consistency? This is a [fundamental problem](https://code.briarproject.org/briar/briar/wikis/Fundamental-Problems) when designing such systems and one that we need to solve in order to advance the discipline and build usable tools that people can rely on.
Cwtch presents a partial solution to the problem through the introduction of a concept called "Untrusted Infrastructure". All participants in a group transcript relay their messages through Cwtch Server, the metadata resistant properties of the system mean that, the server gains no information on which to manipulate the transcript *in a targeted fashion* and as such peers can have some assurance that the transcript they ultimately see reflects reality.
