## 2 Consensus Mechanisms > TODO: needs review, especially if we will use holochain ### Guardian Circles. * 9-99 nodes, each Guardian runs one Guardian Circles Node. Holding all the logic as needed to manage following functions * Checking uptime. * Management of treasury on CHI Chain * Keeping track of capacity used * keeping track of capacity deployed * Providing Proof of Payment (needed for the ZOS nodes to deploy a workload) * Identity Verification * Federation with other Guardian Circles (e.g. around identity and reputation) All data is stored in a replicated database and secured by the Guardian Circle and can be replicated as many times as required by the community. The Guardian Chain functions can be accessed over Open RPC. Technology: tendermint successor + VLANG 3Bot runtime ### CHI Chain Each regional Internet can chose to run on existing money blockchain or deploy an own Money chain. If no CHI Chain deployed then more staking will be required per 3node Up to 99 nodes. Is a cosmos based delegated staking blockchain. The CHI Chain Validators earn money by deploying and maintaining a node. It's a straightforward deployment process. The functions of this blockchain * Digital Currency Functions (CHI and wrapped TFT in treasury). * Identities and Reputation. * Integration with other Public Blockchains through IBC protocol (see Cosmos ecosystem)
