## 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.

## Network and consensus

| Parameter | Details |
|---|---|
| Type | Hosting network for Holochain applications (EdgeNodes and Web Bridge gateways); HOT itself is a token on Ethereum |
| Consensus | None: Holochain is agent-centric, and each participant keeps its own signed source chain |
| Runs on | HOT is an ERC-20 token on Ethereum, bridged to Arbitrum and Base via LayerZero |
| Launched | HOT was issued in 2018 |
| Licence | Holo hosting software is released under the Cryptographic Autonomy License (CAL 1.0) |

## Supply and issuance

| Parameter | Details |
|---|---|
| Issuance | During the 2018 sale the token supply was not fixed in advance; it expanded daily according to crowdfunding sales |
| Initial distribution | 75% to the community through the sale; 25% minted for the organisation, founders, team and prior investors |

## What HOT is used for

- HOT was sold as a placeholder for future HoloFuel hosting credits, originally intended to be redeemable 1:1.
- Holo Limited does not currently offer any exchange, conversion or redemption of HOT; hosting is priced in national currencies such as USD and EUR.

## Who develops and governs Holo

- **Company**: Holo Limited, a Holochain Foundation company
- **Founders**: The Holo Green Paper (December 2017) was created by a team including Arthur Brock and Eric Harris-Braun
- **Open source**: Yes; EdgeNode is an open-source container image, and code is on GitHub

## Official HOT contracts

| Network | Contract address |
|---|---|
| Ethereum | [0x6c6EE5e31d828De241282B9606C8e98Ea48526E2](https://etherscan.io/token/0x6c6EE5e31d828De241282B9606C8e98Ea48526E2) |
| Arbitrum | [0x17e1e5c6bc9ebb11647c94e1c5e3ba619f2781ea](https://arbiscan.io/token/0x17e1e5c6bc9ebb11647c94e1c5e3ba619f2781ea) |
| Base | [0xf3dd141109dfe8e4c006f88a2a8747a086e7c1f8](https://basescan.org/token/0xf3dd141109dfe8e4c006f88a2a8747a086e7c1f8) |

The Ethereum ERC-20 is the original HOT token; the Arbitrum and Base contracts are canonical LayerZero-bridged deployments.

## 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.

## How voting works

Votes are anonymous and carry no text. Each device has one vote per item; press the same button again to remove it. Cloudflare Turnstile checks that a person is voting. We keep a random device ID in a cookie and a salted hash of the IP address to limit abuse — no names, no accounts. Votes are visitors’ opinions, not investment advice.
