BSC & Gitcoin R12 Hackathon : Cross-Chain Interoperability Between Two POSA Based Blockchain

[BinanceG11]

Description

Binance Smart Chain Hackathon :

Binance Smart Chain is proud to be partnering with Gitcoin R12 Hackathon. This is a 3-week virtual hackathon event that features $20,000 in total cash prizes. We welcome all talented developers, builders, and creatives from around the world to build scalable and multichain blockchain on Binance Smart Chain, which is an EVM-compatible high-performance blockchain featuring cross-chain compatibility with Binance Chain.

This hackathon is part of the awareness and effort for BSC $1billion fund to help fast track adoption of digital assets and blockchain technology. For more information : Binance Launches $1 Billion Binance Smart Chain (BSC) Fund to Increase Global Crypto Users to 1 Billion

Challenge Description

BSC is a POSA based blockchain, given there are many sub-chains also based on POSA. Please design a decentralized solution to support cross chain communication between BSC and the sub-chain. A possible solution is that POSA consensus has its light client, try implementing it on chain and verify the cross chain package through SPV.

Prize Bounty

This hackathon features a total of $20,000 BUSD.

Gold (1 team) · $10,000 in BUSD Tokens · Join MVB and Incubation Program.

Silver (1 team) · $6,000 in BUSD Tokens

Bronze (1 team) · $4,000 in BUSD Tokens

Submission Requirements

• Building at least one demo based on the cross chain mechanism, like ERC20 transfer.
• Design doc reviewed/approved by the Binance team.
• A demo video must be submitted for a complete submission.
• Please provide a valid BSC wallet address to receive BUSD.

Judging Criteria

A panel of judges from the Binance Chain team and its partners will evaluate your submission. Here’s the criteria by which your work will be judged :

• Design and usability.
• The solution must be decentralized and trustless.
• The solution should handle the possible chain fork.
• The cross chain communication should be cheap and fast enough.
• The chain is based on BSC.

Winner Announcement Date

• Hackathon Kick-off: Dec 1, 00:01
• Binance Smart Chain Workshops: 1-16th Dec (times TBA)
• Deadline for Submissions: Dec 16, 23:59
• Judging: Dec 17 - Dec 28

Akorn is a regenerative marketplace for incentivizing actions that increase or maintain native ecosystems. We are currently working with hackers during this hackathon to create something environmental/ sustainability related with open source code. We have committed $1,000 of our grant funding (https://gitcoin.co/grants/4006/incentivizing-actions-that-increasing-and-maintain) to any developers that join our team. That means you will get $1,000 in funding just for coding with us. Link to telegram: https://t.me/+awK2bree96ViM2Yx

One possible solution for supporting cross-chain communication between BSC and its sub-chains would be to use a decentralized application (dApp) that leverages the proof-of-stake-authority (POSA) consensus mechanism. This dApp could serve as a light client for both BSC and its sub-chains, allowing them to communicate and interact with each other in a decentralized manner.

The dApp could use the POSA consensus mechanism to verify transactions and blocks on both BSC and the sub-chains, ensuring that all transactions are valid and authorized. This would allow for secure and reliable cross-chain communication and interaction.

Additionally, the dApp could use smart contracts to enforce rules and ensure that all transactions are compliant with the protocols of both BSC and the sub-chains. This would help to ensure that the decentralized solution is secure and efficient, and that it supports the needs of both BSC and its sub-chains.

Overall, using a decentralized dApp that leverages the POSA consensus mechanism could provide a robust and secure solution for supporting cross-chain communication between BSC and its sub-chains.
