Cosmos/Tendermint Hackathon en partenariat avec la chaire Fintech de l’Université Paris-Dauphine
Cosmos/Tendermint Hackathon
Chain Accelerator is organizing, for Tendermint (tendermint.com) and Université Paris-Dauphine’s FinTech chair, a hackathon on April 13rd-14th 2019. To
be won:
- 7 000 € from Tendermint
- 2 000 € from Tendermint
- 1 000 € from Tendermint
- For a TOP 3 project, if the project is accepted by Chain Accelerator, a 6 months incubation at Station F (Paris) will be offered
- For every participant: you will receive a link and first 50 signed up for the Chain Acc-ademy will receive a free ticket for the 2 days event Paris Blockchain Week Summit.
HACKATHON RESERVED TO DEVELOPERS
Each team’s aim is to build a blockchain in its entirety, compatible with Cosmos/Tendermint ecosystem, as well as the corresponding user interface. For this, participants will use Cosmos-SDK, a Golang framework allowing to easily build blockchains from modules.
Place: PARIS Université Paris-Dauphine
- Place du Maréchal de Lattre de Tassigny, 75016 Paris
- Hackathon’s opening at Room Raymond Aron.
- Lecture Hall 2, 3 and 4 for team work.
- Hall 2 for meals
- Room Raymond Aron
Panel:
- Nicolas Cantu co-fondateur Chain Accelerator
- Directeur de la Chaire Fintech chez Fondation Paris-Dauphine
- Gautier Marin: Developer Relations Engineer
- Billy Rennekamp: Developer Relations Engineer
Available Subjects (feel free to suggest some more):
- Proof-of-Authority : module Build a Cosmos SDK module that lets people permissionned validator set. The validator set can add or remove a validator provided 2/3 of current validators agree
- Universal Basic Income : moduleBuild a Cosmos SDK module with an in-built UBI logic
- Module manager : Build an npm-like module manager prototype for the Cosmos SDK Supply-chain blockchainBuild a simple supply-chain application specific blockchain on the Cosmos SDK (with an associated module)
- Local currency system : Build a blockchain the Cosmos SDK that lets people deploy their own local currency.
- DID Auth : Use the DID decentraized identity standard for authorization in a module
- Uniswap Module : Build a module that incorporates X*Y=K market making like that of Uniswap on EthereumDomain Name ServiceBuild a domain name service module like in the tutorial. Bonus: add some more complex buy/sell mechanisms
- Scaffolding Tools : Automate the build process of generating CLI and REST server for new modules
- ETH Token Peg Zone : Implement a zone which acts as a peg between a popular blockchain like ethereum and the cosmos ecosystem
- Wallet : Make a web app wallet that interacts with a cosmos blockchain (bonus use the chain id as a variable so you can switch between chains)
- Whitelist Auth : Let users authenticate off chain and gain access to a white list that gives them special permissions like 0 fees
- Permission To Public Validator Set : Propose a system for transitioning a permissioned validator set to a public validator set
- Validator Assesment : Make a Better Business Bureau-like entity which gives ratings of Validators based on their performance and delegator rewards
- Social Recovery Wallet : Use the multisig capabilites to create a wallet which can be recovered by some threshold of signatures from friends or family
- IBC MVP : Implement a MVP version of IBC (https://github.com/cosmos/cosmos-sdk/tree/develop/docs/spec/ibc) in the language of your choice.
- Governance forum : Build a whole governance platform centered around the governance module (pre-proposal discussion, feedback, etc;)
- TCR : Build a token curated registry that improves upon the ethereum model using fast finality, cheap transactions and asynchronous hooks
Participants: Between 50 and 75 people including: Grandes Ecoles, researchers, ideation startups, engineer and business schools, and independent geniuses.
Come with your team or come to complete an existing team.
