In a world where different types of blockchain are emerging all the time, interoperability between them becomes essential. In the context of Drex, it will be no different. In this context, the workshop “Interoperability between Besu and Fabric with Hashtime Locked Contracts” aims to explore the concept of atom swaps and hashtime lock contracts between a Hyperledger Besu network and a Hyperledger Fabric network. The workshop will be divided into a conceptual and a practical part. This dual approach will allow participants to develop solutions based on the acquired knowledge.

**INTRODUCTION**
The Internet Computer is a general-purpose blockchain that hosts canister smart contracts. Itis designed to provide a World Computer that can replace traditional IT and host a new generation of Web3 services and applications thatrun solely from the blockchain, without the need for traditional IT.
It can also play the role of Web3 orchestrator, by interacting withtraditional blockchains. It has a completely unique design that reflects a ground-up rethink of blockchain architecture and theapplication of modern cryptography, which can be traced back to 2015.
It was built by the largest ongoing R&D effort in crypto,
which has employed many notable cryptographers, computer scienceresearchers and engineers. The blockchain underwent genesis in May 2021 and became part of the public internet.

ICP (Internet Computer Protocol) Track

Internet Computer

Select this track if you're building on the Creative DREX and (w)stETH DeFi **solutions** Track

**👀 Description**

- Lido software provides an infrastructure which other creative projects can use as as abstracted base to support Ethereum decentralization and earn staking rewards
- Through it’s widespread use in Ethereum ecosystem and integrations, one can get inspired to build solutions with DRAX that provably make sense and show traction with other assets like USD stablecoins
- Through this prize, we want to see teams use Lido’s stAssets to solve a pressing issue within your communities - think of creative ways to utilize interoperability between DRAX and stETH to create new ways for the users of DRAX to save/earn and potentially fight off the inflation of fiat currencies
- Whether you decide to build your own dApp, or a custom strategy on one of the existing DeFi platforms - we’re looking for fun, creative projects who want to leverage the power of on-chain staking rewards to solve a problem in their local community and make the world a better place.
- The “end game” for your idea would be integration with PIX (or similar) system in a fully abstracted abstracted way in terms of web3 technical complexities

**✅ Requirements**

- b) Submission can be a dApp, a strategy/vault for existing DeFi dapp, or any other prototype.
- c) Submission needs to leverage (w)stETH in some way
- d) Must submit a project description, a pitch including a demo, a Github repository with a README on how to run the project, as well as a working prototype.
- e) Bonus points for creativity and innovation!

**👩🏽‍⚖️ Judging Criteria**

- a) Having an innovative solution
- b) Real world use case explanation
- c) Understanding and usage of Lido software
- d) Meeting of the requirements
- e) Bonus points for a user-friendly UX and good docs

Creative DREX and (w)stETH DeFi solutions - No projects met the requirements for this award

Select this track if you're building an SDK with Lido Finance

**👀 Description** 

To hide the complexities of Lido’s smart contracts and enable developers to use the Lido software as a “black box”, there needs to be a SDK. If you think of developers from TradFi or banks, you are not immediately thinking of web3 enthusiasts, shadowy smart contract coders and similar. The SDK should provide (but not limited to):

- a) abstracted main opearting flows (staking, withdrawing)
- b) API for protocols/wallets to fetch main data and parameters without digging on-chain data manually
- c) detailed dev documentation

**✅ Requirements**

- A) Submission should include a demo and documentation on how to get the project up and running locally

**👩🏽‍⚖️ Judging Criteria**

- a) Effectiveness of the solution for web3 and non-web3 integrations
- b) Understanding and usage of Lido software
- c) Meeting of the requirements.
- d) Bonus points for a user-friendly UX and great docs
