Credential Corgi
Winning homepage:https://ethglobal.com/showcase/credential-corgi-a 7 a 0 r
Credential Corgi is a credential issuance and certification tool based on GPT 4 and zero-knowledge proof. Its useful scenarios include: supporting the platform to create credential standards, supporting the issuance of ZKP-compatible credentials, and third parties can interact with credential holders . Specifically:
Institutional platforms can use the structural standards of Credential Corgi to issue vouchers, combined with the automatic generation capabilities of GPT-4, without writing specific technical specifications;
Issuers can issue zero-knowledge proof (ZKP)-compatible credentials on institutional platforms and record them on-chain without revealing private information;
Third parties can use GPT-4 to verify credentials without writing technical specifications;
Credential holders can use ZKPs to fulfill these verification requests without revealing any other information.

LocalPro
Winning homepage:https://ethglobal.com/showcase/localpro-xckra
LocalPro is mainly used to solve the management problems between global organizations and scattered workers. The infrastructure it provides can use blockchain to provide on-chain verification and incentives for offline work in various places.
As the world becomes more connected, the demand for off-site gigs continues to increase, but how to test and manage these fragmented cross-regional jobs has become a challenge for organizations. LocalPro uses trustless identity and performance verification to connect global organizations with independent local workers, solves the potential complexity of on-chain coordination through account abstraction, provides a better user experience, and uses ZK-privacy and PolygonID to ensure Data Privacy and Compliance.

CryptoBureau
Winning homepage:https://ethglobal.com/showcase/cryptobureau-u 1389
CryptoBureau aims to use zero-knowledge proofs to build a credit scoring system to enable under-collateralized lending in the DeFi world.
The basic operation of CryptoBureau is that it will give a corresponding credit score based on the proof submitted by the customer, which will then affect the amount of collateral required. If the user owes money maliciously, other protocol participants will be able to check this behavior and refuse additional loans. .

Web3-gpt4
Winning homepage:https://ethglobal.com/showcase/web3-gpt 4-jkaja
Web3-gpt4 is a smart contract management tool built on Chat GPT4, designed to simplify the way developers interact with smart contracts. Users enter Solidity code into the chat interface, select an EVM-compatible blockchain, and the tool takes care of the rest.
The Web3-gpt4 plug-in does not require user authentication, and can easily access and safely process user data through a locally hosted open API. The benefits it can achieve include:
Add contracts: Allow users to add new contracts, helping to track various contracts of interest;
Delete contracts: allow users to delete irrelevant or unwanted contracts from their list;

Donation Station
Winning homepage:https://ethglobal.com/showcase/donation-station-g 09 ok
Donation Station allows users to donate to Gitcoin on Layer 2 through the donation contract it provides, thereby greatly reducing the required gas cost (the latest round of Gitcoin donations only supports the main network, and many donors chose to give up because the gas is too high).

ChainGPT
Winning homepage:https://ethglobal.com/showcase/chaingpt-and-accountability-for-ai-agents-doquk
ChainGPT is a blockchain-based decentralized, verifiable chat AI.
ChainGPT uses Stanford's Alpaca large language model. Unlike ChatGPT, which cannot determine whether the reply content is correct, ChainGPT introduces the concept of "validator node" to verify the authenticity of the reply information.

op-kompressor
Winning homepage:https://ethglobal.com/showcase/op-kompressor-1 uboo
op-kompressor is a set of smart contracts that allow relayers to compress calldata.
The effect of op-kompressor is to decompress the calldata of Ethereum by modifying the encoding scheme of the run length, thereby saving the gas consumption of transaction processing on Layer 2 such as Optimism.
