Threshold is community-driven and governed by an eponymous DAO that includes the constituencies of both the NuCypher and Keep networks. The community decided that a . The Threshold DAO has three primary bodies: Tokenholder DAO, Staker DAO, and the Elected Council. The goal of this three-pronged approach is to enhance representation while ensuring accountability, as each of these governance bodices will hold the other two accountable, similar to the system of checks and balances found in most constitutional governments. They will also hold separate responsibilities that are embedded in the governance structure. See this blog post and this proposal for a more extended description of the DAO structure.
From an implementation perspective, both the Tokenholder DAO and the Staker DAO are based on Governor Bravo governance model (in particular, using OpenZeppelin Governance). The Tokenholder DAO is on Ethereum Mainnet at
