Holochain is intended to be an open source "agent-centric" framework for building distributed peer-to-peer applications. Holochain relies on two different levels, a global level built as a verified distributed hash table, and a local level where each dApp or smart contract has its own database and its own verification rules (i.e. "DNA"), including an optional consensus mechanism. This means that Holochain contains a ''chain'' in each application. The global level ensures data redundancy to ensure data availability, and acts as a bridge between dApps to declare violators of local validation rules in the form of gossip. Holo, on the other hand, is a distributed peer-to-peer hosting platform for Holochain applications, and Holo uses a variant of proof of authorization called "proof of service" where the past behavior of various dApps is used as "authorization" or "The purpose of this is to allow access to Holo-based applications. The goal is to allow people to access dApps built on Holochain without having to run the Holochain engine themselves. As a result, Holo is "committed to hosting Airbnb''s services to hotels over the web: anyone can become a host by turning their computer into a revenue stream and earn revenue through HoloFuel to host distributed applications". Approximately 133 billion ERC-20 tokens, HOT, can be exchanged for HoloFuel ("HOLO") at a ratio of 1:1, but do not have to be destroyed, just made non-circulating. HOT is intended to act as a bridge between HOLO and other crypto assets. HoloFuel is based on Holochain cryptocurrency, representing contractual service obligations, redeemable in escr
