What is Holo
Holo is a hosting network run by Holo Limited that provides always-on nodes and web gateways for applications built on Holochain, a peer-to-peer framework that does not use global consensus. The Holo Token (HOT) is an ERC-20 token sold in 2018 as a pre-sale voucher for HoloFuel, the network's planned hosting currency, which has not launched.

Risks and caveats
- HoloFuel has not launched, and Holo Limited does not offer redemption or conversion of HOT.
- Any future HOT redemption is subject to regulatory requirements and would be run by licensed third parties, not Holo Limited.
- The original sale terms state that HOT confers no rights or equity interest in Holo.
- Holo describes its whitepapers as a record of design intent, not a description of the network today.
