All development skills are welcome. No matter if you are an expert or beginner with an interest in Bitcoin Cash, Bitcoin, Ethereum or other blockchain projects, you will have fun!

Build decentralized applications using Bitcoin Cash or other blockchains from scratch. Participants can compete on two different tracks:

Bitcoin Cash Track [€3,500 Paid in Bitcoin Cash]

Build cool stuff using the Bitcoin Cash Blockchain. Create a product that makes use of the new OP codes, larger block size, Wormhole protocol, tokenization, smart contracts or utilizes Bitcoin Cash in other meaningful way.

General Blockchain Track [€1,500 Paid in Bitcoin Cash]

Create the best product using the blockchain of your choice: from Bitcoin, Bitcoin Cash to Ethereum or innovate with second layer solutions such as the Lightning Network. You are limited only by your imagination!


Is this event for me? This hackathon is for everyone who is interested to learn more about Bitcoin Cash and other blockchains. It's especially recommended for developers who want to learn how to build blockchain apps.

How much is the ticket? Good news, the event is 100% free! All food and drinks are included as well as some extra goodies. Since you can sleep at the venue overnight, you can even save the hotel cost.

How are teams formed? We prefer teams to be formed on the spot. This allows everyone to meet new people and keep an open mind. However, you are absolutely welcome to bring your friends.

What will I do for 32 hours? Code, brainstorm, play games, attend a workshop, have a pizza, take a nap, go for a walk. You have 32 hours to create your winning project!

Do I need coding skills? Development skills are useful but not required for all participants. Every team needs a mix of skills: developers, blockchain experts, creatives, business minds, designers and others.

Some examples of projects 

  1. Build a micropayments project with feasible innovations in fast payment integrating BCH’s features: borderless, 0 confirmation and low transaction fees.
  2. Build a betting game based on newly released op codes, e.g.: https://github.com/fyookball/ChainBet. This topic can be without considering the funding problem, atomic operations, smart contracts, and eventually sent tokens according to the results.
  3. Build an application regarding permanent data storing, open protocols and open-source data. (Using Op_Return) e.g.: https://memo.cash/
  4. Build a cross-chain project, implementation based on gateway designs. Building an internet of value and ecosystem. E.g.: https://www.rsk.co/
  5. Build an analysis tool for big data. A tool that can detect, inspect and visualize the transaction, tradings, blocks, nodes and the entire network of BCH Blockchain. E.g.: https://blocks.wizb.it/
  6. Build a WHC Block explorer. Call Wormhole REST endpoints (https://wormholecash-production.herokuapp.com/) to build a web GUI which lists the tokens, token details, balances of token holders and transactions for token/holder.
  7. Build a utility token generator w/ SLP. Create a web GUI which lets a user create a new SLP token. Name, ticker, URL, number of decimals, fixed/managed supply and initial distribution.
  8. Launch an ICO on WHC. Create a custom security token and launch a crowdsale. Custom name, ticker, total number of tokens and how many tokens you'll sale for each 1 WHC.
  9. Conceptualize a stable-coin for BCH ecosystem. Stable-coins, like DAI and $GUSD, are very popular in the ETH token ecosystem. Brainstorm on what a BCH stable-coin would look like. What smart contracts are needed in WHC for this to happen?

And many more!
