Decentralized collaborative version control

Decentralized systems offer alternatives to Big Tech. However, maintaining availability and correctness despite faults and manipulations in decentralized settings is challenging. In this paper, we introduce a collaborative model that is capable of exposing all observable lying, all cheating, and all faults, while only requiring merely...
