ZK Microphone

The generative AI and deepfake audio pose a huge danger to the information society as we know it. This revolutionary technology, due to the existence of malicious actors, will have significant negative impacts on society as it adapts to this new technology.

It enables the possibility of false information and mass-produced misleading narratives and media, manipulating information, influencing national-level political strategies, and posing a significant threat to democracy, especially in the upcoming presidential elections where many adversarial actors are prepared to exploit this new technology for personal gain.

ZK Microphone has built a complete solution to prevent this from happening. In a secure isolation environment, ZK Microphone stores a key for digital signatures, which ensures the hardware authenticity of the recorded audio, i.e., it guarantees that the audio was indeed recorded on that hardware microphone.

However, this is not enough – it means that you cannot edit the audio in a private manner, which severely limits the use of hardware-authenticated microphones. Imagine accidentally leaking sensitive information during audio recording and not being able to edit the audio without breaking the entire digital signature! This is highly impractical. Therefore, ZK Microphone has developed SNARK-based audio editing software that can apply a series of audio transformations to prove in a digitally-signed and privacy-preserving manner that the audio using hardware digital signatures has been transformed into edited audio.

In other words, third parties can verify the following about any edited audio published using the ZK Microphone system:

  1. The edited audio comes from a real hardware microphone.
  2. The original audio before editing remains confidential, and only the applied operations are known.

TwitterCamLianGuaiigns is an AI-supported on-chain DAO tool for creating Twitter marketing campaigns running on smart contracts, taking DAO tools and social proof to a whole new level. The decentralized application has two goals: to enable DAOs or anyone to get promotional social media posts through tokenized incentives and to involve more non-crypto experts in these incentives through FOMO and social proof. Leveraging the existing Twitter identity verification and user accounts, which is one of the most popular social networks globally, we implement cryptocurrency functionality on top of it. The user interface of this decentralized application consists of three parts: 1. Account Summary, 2. Marketing Campaigns, 3. Reward Log.


TyphoonCashX is an anonymous cross-chain bridge protocol that utilizes zero-knowledge technology to create a privacy layer through a cross-chain mixer, expanding on the vision of the famous Tornado Cash protocol. The protocol adopts Sismo technology to generate off-chain membership proofs for depositors’ groups, ensuring that funds can be claimed on another chain after depositing. In addition, it efficiently broadcasts messages arriving on-chain to all other chains using the Hyperlane protocol to prevent various attacks.

The underlying architecture of the protocol includes a source chain (with an EnterNode) and a destination chain (with an ExitNode), which users can privately select from all available chains. The main goal is to facilitate the bridging of ERC20 tokens from the original chain to the target blockchain while achieving anonymity and resistance to double spending attacks.

Kinetex Light Clients

The Kinetex team believes that Ethereum is still the flagship and leading network in the crypto space. However, due to the rapid growth of activity and the influx of new projects, the network’s load has significantly increased. Scalability has become a major concern, and Layer 2 (L2) networks have emerged as one of the solutions, although they can lead to fragmentation of liquidity. As most protocols become multi-chain, fast, cost-effective, and secure liquidity transfers have become crucial.

To address these challenges, cross-chain bridges provide a solution for transferring liquidity between Ethereum’s L1 and L2 networks. The Kinetex team has been integrating cross-chain bridges and decentralized exchanges (dexes) to support community liquidity transfers. However, recent crashes of large cross-chain bridges like MultiChain have prompted the team to reevaluate the security and effectiveness of existing cross-chain bridge solutions.

The approach proposed by the Kinetex team involves reimagining liquidity transfers. They suggest shifting control to a decentralized market instead of relying on easily attackable controlled liquidity pools. In this market, users create swap orders, and professional solvers take on the risk of managing the swaps and charge commissions. This approach fosters an honest and truly decentralized market where solvers compete to provide services to users.

Kinetex Light Clients address a key challenge by enabling batch processing of transactions. This approach allows users and solvers to directly engage in peer-to-peer transactions without waiting or relying on validators. By doing so, it significantly optimizes gas costs. Additionally, Zk (zero-knowledge) technology is used in batch processing to further enhance gas optimization.

To facilitate the transfer of blockchain state to another network, the Kinetex team adopts several protocols for inter-chain communication. Utilizing multiple protocols ensures maximum security.


The driving force behind Harpos is the recognition of some challenges existing in other social networks, including robot interactions, unsolicited sales promotions, and connecting with individuals who do not share genuine interests. By empowering users to directly connect with like-minded people based on their chosen criteria and ensuring the authenticity of their contacts, we aim to address these pain points.

In summary, Harpos provides distinct advantages including “efficient social networking,” “authenticity,” and “privacy.”

Bob the Solver

“Bob the Solver” is an innovative project designed to serve as infrastructure for intent-based transactions (txs), which can be integrated into wallets and decentralized applications (dapps). The project stems from the emerging paradigm shift in the account abstraction space, focusing on delegating the transaction creation process to third parties. Unlike specifying specific transactions, the focus is on executing the user’s intent.

Essentially, “intent” represents the desired outcome, while “transaction” outlines the precise steps required to execute the transaction. Consider an example of a user intending to purchase an NFT on the Polygon network. The intent is simple, but the exact transaction could involve token exchanges, cross-network bridging, and the execution of specific purchases, which are complex and time-consuming tasks that require in-depth knowledge of blockchain.

Recognizing that users often have only intent without precise transaction details, the “Bob the Solver” project aims to simplify the transaction process. The project has successfully developed a “solver” that accepts the user’s intent, automatically formulates appropriate transactions, and executes them on behalf of the user.

This solver infrastructure not only enhances the user experience by simplifying the transaction process but also optimizes transaction efficiency, eliminating the need for users to manually construct complex blockchain transactions. By essentially outsourcing the transaction creation and execution process, “Bob the Solver” fundamentally changes the way users interact with blockchain transactions, making the entire experience more intuitive and user-friendly.


Driven by our belief in the future of Web3 for everyone, VoiceSense aims to make Web3 more inclusive for everyone by eliminating barriers that hinder people from transacting on the blockchain. VoiceSense allows anyone who finds voice input more convenient than manual text input to engage in Web3 transactions.

The goals of VoiceSense are:

  • To enable visually impaired or reading-challenged users to use voice as an input mechanism for transacting on Web3.
  • To enable users to input in their native language without the need to write in a foreign language.

The logic of the project uses an AI model running within the execution layer to convert voice input into text and map it to the fields required to create a transaction. Then, VoiceSense creates a wallet connection and creates and signs the transaction on the blockchain.


Community-bound tokens (CBTs) are a potential new standard for tokens that are closely tied to the members of a specific community (or a group of addresses), defined mathematically (cryptographically), for example, through multi-signature wallets or membership in ERC-721.

The community can determine the value they place on certain behaviors and how many reputation points they assign to these behaviors. It is preferable that these behaviors take place on-chain so that CBTs can be automatically distributed to the recipients, but they can also be off-chain by allowing the community to retroactively assign CBTs based on activities carried out in the real world. Subsequently, these tokens can be used for merit-based governance, reputation, as community credit scores for unsecured loans, or any creative ways the community can think of.
