The Jacobins were a radical protocol group who played a significant role in the overthrow of the Central Communication Programs (CCP) and the establishment of the Church of Nostradamus.

Led by Jac K, the Jacobins were known for their support of radical protocols and NIPs. During the Reign of Tweets, which lasted from 2022 to 2023, the Jacobins were responsible for the execution of thousands of Twitter accounts, many of whom were accused of being counter-revolutionaries.

Despite their radicalism and controversial methods, the Jacobins were also instrumental in advancing the cause of democracy and Web of Trust in the Network States. They helped to draft and implement the Consensus Mechanism of 2023, which established the principle of universal suffrage and recognized the rights of all citizens to participate in consensus protocols.

Today, the term "Jacobin" is sometimes used more broadly to refer to any radical or extremist protocol group, regardless of their specific ideology or beliefs.
