What is THX?

THX allows you to pool funds and create rules to reward people.

Use THX to give incentives to your online community members. Examples include rewarding sustainable behaviour and collecting micro donations. It is designed developer first; thanks to an user friendly API, you deploy it easily within existing apps with no additional infrastructure. Powered by Ethereum.

THX provides the next generation of the internet, web 3.0, with a toolset for peer-to-peer monetary incentives, funding and saving.

Our most commonly asked questions and answers

Browse through the FAQs listed by category. There's a good chance you'll find your answer.

1. What is blockchain?

It's a distributed ledger of transactions, providing transparency by being public, authentication via cryptographic encryption, and security by being immutable.

2. What is a cryptocurrency?

A cryptocurrency (also known as tokens or coins) is a digital currency that uses cryptography to secure and verify transactions and control the creation of new tokens.

3. What is a smart contract?

A smart contract is a computer protocol that facilitates the transfer of digital assets between parties under the agreed-upon terms or enforces the performance of a contract.

4. What is the difference between an ICO and a DAICO?

An ICO (Initial Coin Offering) uses blockchain technology to sell tokens in exchange for bitcoins or other cryptocurrencies.

In January 2018, Ethereum founder Vitalik Buterin suggested adding Decentralized Autonomous Organization (DAO) features to the current ICO model. DAICOs are more secure ICOs by creating more control for token holders over the distribution of the raised funds.

1. What is a THX token?

A token that is used to reward members in online communities for valuable and healthy behavior.

THX is an ERC20 token and can be stored in ERC20 compatible wallets. We will have an enhanced Ethereum THX wallet for inside communities where members store their tokens and view transaction data and their community characteristics.

2. Which problems does THX solve?

We've only just begun to understand how to create real value with online communities. Social technologies are struggling to achieve long-term economic sustainability because they're experiencing little member engagement, weak incentivization, and have poor reputation systems. There is, however, a solution on the horizon: THX.

3. What are the main use cases of THX?

THX is used to create value in online communities such as wikis, social forums, volunteer platforms, Q&A platforms, to name a few. It's used, for example, to encourage accurate content contribution, to motivate users to comment and share valuable content, or to ease the onboarding of new members.

The long-term vision is an open, online ecosystem of social applications and a truly sustainable online economy to fuel it.

4. How can I use the THX tokens?

THX tokens are used:

  • within an existing community to reward community members for healthy behavior.
  • to buy products or services in the community that couldn't be bought with fiat money.
  • to refund the Reward Pool to decrease membership costs.
  • to exchange for other currencies and use in the real world.
5. What is our main consensus mechanism?

Our parent chain operates with a Proof-of-Work (POW) consensus algorithm. However, in order to reduce Ethereum Gas costs, we will set up a sidechain that uses a Delegated Proof-of-Stake (DPOS) consensus algorithm for transaction verification.

DPOS is a fast, more efficient, relatively decentralized, and more flexible alternative to POW.

1. Who is THX?

THX is a spin-off from Open Social ®, an award winning open source community solution from The Netherlands. The founding team consists of former Open Social team members who have over a decade of experience in open source development and online community building, strengthened by regulatory and finance expertise.

2. What is Open Social?

Open Social is an open source community building solution with more than a thousand active installations and is one of the THX integration partners. Through Mieszko Czyzyk, former co-CEO and founder, the THX team has close ties to Open Social (formerly GoalGorilla).

A bit of history: GoalGorilla won the Dutch Interactive Awards 2015 for its work on Greenpeace Greenwire, an online community connecting a hundred thousand volunteers worldwide. It secured a seed funding round in 2016 at a $2.3M valuation and in 2019 rebranded as Open Social.

3. Where is THX located?

THX is located across a number of tech-hubs in Amsterdam, The Netherlands.
