ZK Microphone

Award homepage: https://ethglobal.com/showcase/zk-microphone-8161v

Keywords: Zero-knowledge proof

ZK Microphone aims to create a trustworthy audio verification service in the era of rampant deepfakes, utilizing ZK-SNARKs.

Generative AI and deepfake audio have posed a huge threat to our social security. In order to suppress the spread of this problem, ZK Microphone has built a full-stack solution - a verification service for audio using ZK-SNARKs.

The basic operating principle of ZK Microphone is to store the secret key used for digital signature in a secure enclave, ensuring the authenticity of the recording, i.e., confirming that the audio is indeed recorded from the specified hardware microphone. At the same time, ZK Microphone also uses audio editing software powered by ZK-SNARKs to transform the original audio to ensure the privacy of the original audio content while ensuring the verifiability of the digital signature.

GLSwaps

Award homepage: https://ethglobal.com/showcase/glswaps-grandma-leveraged-swaps-gzit8

Keywords: DeFi, leverage.

GLSwaps aims to provide Uniswap with the ability to perform leveraged trading on the frontend.

Specifically, GLSwaps will allow users to engage in various leveraged trading on GMX through the Uniswap frontend via a browser extension. Trading instructions can be submitted through the Uniswap frontend, but the actual execution of trades will be completed on GMX. For tokens supported by both Uniswap and dYdX, GLSwaps allows users to go long or short with up to 50x leverage, thereby increasing capital efficiency.

TwitterCampaign

Award homepage: https://ethglobal.com/showcase/twittercampaign-wv9we

Keywords: DAO, AI

Twitter Campaigns is a chain-based DAO tool that supports artificial intelligence, used to create smart contract-based Twitter marketing campaigns, thereby improving the service level of current DAO tools and social proof.

Twitter Campaigns aim to achieve two goals: first, to enable DAO organizations or anyone to promote social media posts through token incentives; second, to leverage FOMO psychology and social proof to encourage more non-crypto professionals to participate in these incentives.

TyphoonCashX

Award homepage: https://ethglobal.com/showcase/typhooncashx-p10yd

Keywords: Zero-knowledge proof, cross-chain.

TyphoonCashX is a privacy-oriented cross-chain protocol that will allow anyone to bridge any ERC-20 native token on any EVM-compatible chain anonymously.

TyphoonCashX uses zero-knowledge proofs to create a privacy layer for cross-chain mixer, extending the vision of the well-known mixer application Tornado Cash. In terms of the process, during the deposit phase, TyphoonCashX uses the Sismo protocol to generate off-chain identity proofs for users, which qualify them to receive funds on another chain; during the bridging phase, TyphoonCashX uses the Hyperlane protocol to broadcast messages from the arrival chain to all other chains, preventing various attacks; during the withdrawal phase, the protocol verifies the identity proof of the relevant address, and once it matches, the address will be removed from the registry and receive funds at the output address.

Kinetex Light Clients

Award homepage: https://ethglobal.com/showcase/kinetex-light-clients-mmr-uvzr1

Keywords: Cross-chain

Kinetex plans to launch a decentralized cross-chain solution that is different from existing bridging protocols.

Kinetex states that the method proposed by the team involves reimagining the way liquidity flows, with the suggestion of transferring control to a decentralized market rather than relying on a vulnerable liquidity pool. In this market, users can create (cross-chain) trading orders, and professional analysts take on the risk of managing the trades while charging a certain commission. Kinetex believes that this approach can facilitate a truly decentralized market, where analysts must compete for the opportunity to serve users.

Kinetex also mentioned that Kinetex Light Clients will solve the high gas consumption problem of cross-chain by enabling batch processing transactions. This solution allows users and parsers to directly conduct peer-to-peer transactions without waiting or relying on validators, which can significantly optimize gas consumption.

Kinetex's solution is built on Hashi adapters, which the team has specifically developed for various cross-chain messaging protocols such as Chainlink CCIP, Axelar, Hyperlane, and Zetachain. This enables Kinetex to support lightweight clients for many networks, including Ethereum, Gnosis, Polygon, Linea, Celo, and more.

Harpos

Award homepage: https://ethglobal.com/showcase/harpos-0wpcc

Keywords: Zero-Knowledge Proof, Social

Harpos has built a social network that allows users to choose to join anonymously by utilizing zero-knowledge proofs of the Sismo protocol and the XMTP messaging protocol.

On this network, users can log in through Sismo's SSO and create a ZK proof (proving their asset level). In addition, users can generate another ZK proof to prove their social media influence (such as Twitter followers). After joining the network, users can search for other users according to their own standards (personal situation, asset level, social media influence), and then only have private chats with objects that meet their requirements (driven by XMTP).

In short, Harpos hopes that users can directly establish contact with like-minded people based on their chosen criteria and ensure the authenticity of their contacts.

Bubbles

Keywords: Zero-Knowledge Proof, Social

Bubbles is a voice chat platform customized for on-chain communities.

Bubbles integrates four important components to create a seamless and secure experience: first, Ethereum, which allows users to log in directly with their Ethereum wallet; second, Daily.co, which provides Bubbles with a smooth and immersive voice communication environment; third, the blockchain data indexer Airstack, which allows Bubbles to implement token access control, only allowing users holding relevant tokens to enter the chat channel; fourth, Sismo, which allows Bubbles to verify users' membership in specific data groups without exposing their real identities.

Stake Garden

Award homepage: https://ethglobal.com/showcase/stake-garden-7tj7j

Keywords: DeFi, liquidity mining

Stake Garden is a self-managed liquidity staking token investment portfolio, where users can decide the allocation of various liquidity staking tokens within the portfolio (such as choosing 50% stETH, 20% rETH, and some others), in order to adjust the returns and risk situation, ensuring the safety and controllability of their staking exposure.

If users do not want to create their own investment portfolio, Stake Garden will also provide some recommended allocation strategies that users can directly choose to use their preferred strategy.

Cypher Deposit

Award homepage: https://ethglobal.com/showcase/cypher-deposit-cnhs5

Keywords: Zero-knowledge proof, privacy.

Cypher Deposit provides a new privacy solution that allows individuals, businesses, and high net worth individuals to make anonymous transfers in a simple and secure way, protecting their financial and transaction details.

The core feature of the Cypher Deposit solution lies in the use of ZKBOB technology to ensure the privacy and off-chain nature of transaction details. This ensures the confidentiality of user financial activities and prevents tracking and monitoring by third parties.

Cypher Deposit is also hosting a private HOPR container on Filecoin Bacalhau, providing secure access to the Optimism blockchain. This additional layer of security ensures that users' transactions are protected, thereby enhancing their financial privacy throughout the withdrawal process.

The front-end of Cypher Deposit is also hosted on the IPFS protocol. This is done to provide users with a transparent and trustworthy platform, while retaining complete control over their financial assets.

Bob the Solver

Award homepage: https://ethglobal.com/showcase/bob-the-solver-yxtgp

Keywords: Account Abstraction

Bob the Solver aims to be an "intent"-based trading infrastructure integrated into wallets and decentralized applications. The project stems from a new paradigm shift in the field of account abstraction, with its core focus not on the precise transaction process, but on the user's ultimate "intent".

"Intention" represents the expected result, while "transaction" outlines the precise steps required to execute the transaction. For example, if a user intends to purchase an NFT on the Polygon network, the "intention" is simple, but the precise transaction may involve a series of complex and time-consuming tasks such as currency exchange, cross-chain transfer, and purchase, requiring a deep understanding of various blockchain knowledge.

Bob the Solver means that users usually only have "intentions" without precise "transaction" details. This project aims to simplify the transaction process. It will accept the user's "intentions", automatically formulate appropriate transactions, and execute them on behalf of the user.

VoiceSense

Award homepage: https://ethglobal.com/showcase/voicesense-yfzpq

Keywords: AI.

VoiceSence aims to make Web3 more inclusive by reducing barriers to blockchain transactions.

Specifically, VoiceSence aims to provide convenience for anyone who finds voice input more convenient than manual text input, such as users with visual impairments or reading difficulties who can use voice as an input mechanism for Web3 activities, or users who can record input in their native language without having to write in other unfamiliar languages.

The operating logic of VoiceSence is to use an artificial intelligence model running in the execution layer to convert voice input into text and map it to the fields required to create a transaction. Then, a wallet connection is created to create and sign the transaction on the chain.

Community-bound

Award homepage: https://ethglobal.com/showcase/community-bound-y73ys

Keywords: DAO, governance

Community Bound Tokens (CBT) directly translates to "Community Bound Tokens". This is a potential new token standard.

CBT can only be transferred within the community, and the community can decide their value assessment of certain actions, and then distribute CBT as reputation points. Actions that can affect value assessment are best done on-chain, so that CBT can be automatically transferred to the distribution target through smart contracts. However, the community can also decide to distribute CBT points by contributing to certain activities in the real world based on certain criteria.

CBT will have many potential use cases within the community, such as being used as an evaluation standard for community governance weight, or as a credit score for unsecured loans. In short, it can be used in any innovative way that the community can think of.
