  • General Blockchain Track: 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!

Let’s build stuff. 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!

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!
