Cross-Chain with Trustless Bridges

Track 3 - DeFi/NFT/DAO. Metamask, Web3.js, randomness opcode, FlyClient bridges vs rollups, BLS aggregated signatures


The first hackathon theme is Cross-Chain with our trustless, on-chain bridges. The 4 tracks — Liquidity, Middlewares, DeFi/NFT/DAO, Platform — emphasize the current product-market fits of decentralized applications but across multiple chains. Developers can make use of Harmony’s rich ecosystem: a cross-chain API for aggregation and asset pools; Ethereum-compatible indexing, names, and toolkits; and, unique technical features including randomness opcode, on-chain delegation and aggregated signatures, FlyClient bridges, and fast state sync with message gossips.

Besides advancing these cross-chain infrastructure, there are also many product ideas that can take advantage of our trustless bridges. For example, building arbitrage bots with our partner Hummingbot or integrating stablecoins and saving products with our Terra bridge. Harmony has also launched Bulletproof and Poseidon Hash functions for privacy coin mixers like Tornado Cash. (more)


Here are our guidelines for prizes and grants for Harmony’s $1 million hackathon (https://hack.harmony.one).

There are 3 main themes and within each theme there are 4 tracks. Those are listed below.

For each of the 12 tracks, the prize pool is $81,000. The judges and Harmony team will have full discretion to select the following winners and prizes:

Top Prize: $20,000 Second Prize: $10,000 Third Prize: $5,000 Pool Prize: $6,000 divided up for all projects with a qualified submission: a smart contract deployed on Harmony mainnet / testnet. The pool prizes are entirely up to the discretion of the judges.

Each track will then have 4 follow on grants of $10,000 each to give out in the 4 months after the hackathon for any winner reaching any of the goals:

launch on mainnet with 1000 users $100,000 in venture or DAO funding a 3-out-of-5 multisig DAO with 100 on-chain votes These milestones must be reached by January 31, 2022 before the grants expire.

For each track, there will be a 9-person multi-signature wallet of $40,000 and those signers will give out the 4 grants. The 9 people will be the top 3 winners, 3 from the pool prize and 3 from the judges, Harmony DAOs (community, validator), developer captains, and pangaea captains.

The multi-sig holders will decide on the 4 follow-on grants, though we ask that all follow on grants be posted in the Harmony forum (here) with strong support from the community.

In addition to the 12 Harmony tracks, we are working with Terra, Chainlink, Sushi, Maddock Capital, and Hashkey on a challenge with the following prize structure: $20K for top prize, $10K for second, $5K for pool prize, and 2 follow on grants of $10K to be decided by the prize partners.

Track 3: Cross-Chain - “DeFi/NFT/DAO” - We are building an NFT Collectable Fighting Game that is powered by the Harmony blockchain and Unity. The game focuses on some popular mechanics in crypto: minting ownable NFTs, gaming, and play-to-earn. The project showcases the benefit of low cost, fast transactions that are possible on the Harmony blockchain. The game will have a free, or very low cost of entry, which is currently not achievable on other chains like Ethereum.
