  • 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.
