Graphite: Using SNARKs for large-scale on-chain computation
Project URL:
https://github.com/AlexCheema/Graphite
Overview:
Graphite is a lightweight graph property proof protocol using SNARKs, designed to address the challenges of efficient and accessible graph computation on-chain.
(TechFlow note: Graph computing is a computational method based on graph models, primarily used to solve processing and analysis problems involving large-scale graph data.)
Currently, performing graph computations on-chain is both painful and expensive, despite their significant utility across various applications. Additionally, the developer experience (UX) of writing validity circuits—such as those in circom and halo2—is cumbersome for non-experts, making it essentially inaccessible.
This complexity limits broader adoption and innovation. Furthermore, collecting relevant data for these graph computations during extensive on-chain data processing poses major difficulties.
Graphite aims to simplify these processes, making graph computation more feasible and user-friendly, thereby opening new possibilities for developers across various domains.
Phoenix.Fi: Activating Filecoin storage ecosystem through DeFi design
Project URL:

zkP2M provides a trustless, KYC-free, low-cost entry channel from Indian Rupees to USD, reducing fraud by matching users directly with merchants.
FlockChain: A federated learning network built using PoS and Rollup
Github:
https://github.com/BlocSoc-iitr/FLockChain
Overview:
FlockChain is a federated learning network built on PoS and Micro-rollups.
Artificial intelligence is rapidly advancing and having a significant global impact. However, training AI models is often costly and privacy-invasive. Federated learning offers a solution: a decentralized network of clients can train machine learning models while preserving privacy. A major issue in federated learning is malicious clients that reduce the network’s accuracy.
FlockChain addresses this through PoS. Clients holding data and responsible for model training must stake a certain amount, which can be slashed upon detection of malicious behavior. This provides economic security for the network.
FlockChain also uses Stackr to build a micro-Rollup, maintaining the state of model parameters trained by each client after every period. The Rollup acts as a Model Parameter Sharing (MPS) chain, where verifiable off-chain computations are performed to enforce slashing conditions.
Ultimately, users can access highly accurate trained models without needing to set up the infrastructure required to train similar models themselves. They pay for this service, with fees distributed to clients. The protocol also collects a small fee to sustain the network.
hIVM: A virtual machine for rapid intent integration
Github:
https://github.com/AmanRaj1608/hIVM
Overview:
hIVM solves a key challenge faced by intent-based solutions in current decentralized applications (DApps).
Currently, developers face two distinct approaches: highly complex general-purpose networks like Anoma, and specialized, use-case-specific models like UniswapX and CowSwap. This dichotomy forces developers to choose between the flexibility of general approaches and the simplicity of specialized solutions—often at the cost of efficiency and ease of integration.
hIVM introduces an innovative solution that merges these two paradigms.
By providing a domain-specific language (DSL), it allows developers to retain a degree of declarative programming—specifying what needs to be done without getting bogged down in how to do it.
At the same time, hIVM enables them to outline a high-level, imperative workflow for their application. This unique combination facilitates the creation of DApps that are both flexible in design and efficient in operation.
Safe2Link: Secure crypto transfers via links
Project URL:https://safe2link.xyz/
Overview:
Safe2Link is a dApp that makes crypto transfers more convenient and secure.
When making crypto transfers, it's common practice to first test the recipient address with a small amount, since transactions cannot be canceled once confirmed. Even in the crypto gifting space, we typically rely on custodial services to ensure smooth execution.
But Safe2Link might change that—by enabling crypto transactions through specific links.
Within Safe2Link's provided link, users only need to enter the transfer amount and token type; the system automatically generates a dedicated link for them.
Users can then share this link with the intended recipient, who simply clicks it to clearly see the transaction details—including amount and token—without needing to carefully verify wallet addresses. It’s as simple as sharing everyday content via a link.
Behind the scenes, this link is powered by Safe’s programmable wallet.
KhabriChain: A blockchain-based whistleblower system protecting reporter privacy
Github:
https://github.com/J0SAL/decentralized-innovators
Overview:
KhabriChain is a decentralized whistleblowing system that empowers citizens to anonymously report criminal activities.
It is reported that approximately 75% of Indian citizens are unwilling to provide crime-related information to the police. Only a minority are willing to report illegal or unethical behaviors around them, while most choose to ignore. KhabriChain aims to address this issue by allowing users to anonymously report any criminal activity, focusing on improving real-time detection and prevention rates without compromising user privacy.
Masala Wallet: A wallet using ZK for password recovery

Multilane: Asset transfers without cross-chain bridges
Project URL:https://multilane.xyz/
Overview
Multilane is a protocol enabling interoperability of assets without traditional cross-chain bridges.
Currently, tokens on one chain cannot be directly used on another. To use tokens on a different chain, users must first bridge them—a process that, while functional, presents several issues:
-
Bridging assets takes time.
-
Cross-chain bridging incurs fees.
-
Funds become fragmented across different chains.
To address this, Multilane offers the following solution:
With Multilane, users deposit funds into L1 and can then use those funds on any chain without bridging, because Multilane sponsors user transactions (including ERC20 and native tokens).
When withdrawing deposited funds, users have two options:
-
Request withdrawal from a Multilane node.
-
Trustless withdrawal: Different blockchains communicate via bridging to prove the legitimacy of withdrawals, enabling withdrawal without approval from any party.
CrypticCloak:
Project URL:
https://github.com/Dhruv-2003/ETHIndia23
Overview
CrypticCloak is a stealth-address-based, EVM-compatible micro rollup that helps leverage Ethereum’s consensus layer and security on any L2 or EVM-compatible chain.
A major challenge facing Ethereum is privacy, as public blockchains by default expose all information publicly—not just financial transactions, but also assets like POAPs and NFTs. Using Ethereum applications means exposing a significant part of one’s life to public view, raising privacy concerns in various scenarios.
CrypticCloak addresses this by providing infrastructure that obscures one end of transactions. CrypticCloak also offers an interoperable and robust solution usable on any EVM-compatible chain.
-
The project provides an off-chain but verifiable single-point registry for all EVM-compatible chains.
-
Instead of heavy zero-knowledge computations, it uses only cryptographic computations to reduce gas costs and execution time while delivering the same level of privacy.
-
User identities cannot be traced back; even if they could, the data would be meaningless.
-
Built on Micro Rollup, it helps leverage Ethereum’s consensus layer and security on any L2 or EVM-compatible chain.
CrypticCloak is also compatible with any EVM-compatible chain, offering an interoperable and powerful solution.
