# **Announcing the winners of ZecHub Hackathon 3.0!** Firstly, a huge thanks to every Zcasher that worked on one of the 36 projects submitted. This hackathon has been monumental in terms of participation, novelty and quality of submissions. Many projects that did not win this time should 100% continue developement. From May 25th to July 15th developers in the ecosystem built across 5 tracks: **Infrastructure, Games, FROST, Zcash Login and Accounting**. Participants created working prototypes that explored new ways to use Zcash for private identity, collaborative custody, financial management, infrastructure and interactive games. Congratulations to everyone who had an idea, built it, documented it & demonstrated it to the community. **Read the full article featuring all projects, descriptions and video demos:** > **[🎉 Announcing the winners of ZecHub Hackathon 3.0!](https://zechub.substack.com/p/announcing-the-winners-of-zechub)** > > Firstly a huge thank you to every developer and Zcash community member that worked on any of the 36 projects submitted. During project reviews DAO members were asked to consider: 🔸How well each project works 🔸How meaningfully it uses the Zcash network/features 🔸Completeness 🔸Originality 🔸Potential ecosystem impact 🔸Documentation quality and ease of testing The winners were selected through a 2 stage vote by the ZecHub DAO. First, we used first-past-the-post voting within each track to select the highest supported project, producing 5 finalists, one from each category. The finalists were then ranked using Bloc STAR voting, scoring each project before a final runoff determined the order. The complete voting process was conducted twice, both votes producing the same finalists! With that, we are excited to announce the winners! 🙌 ![image](https://global.discourse-cdn.com/zcash/original/3X/d/8/d86b9f15cae00a1668d776c81919cc4701fb5d80.jpeg) Created by @orbism([@ArtofOrb](https://x.com/@ArtofOrb)) ZEC-OS presents the Zcash ecosystem through a customizable retro desktop interface containing an explorer, mempool viewer, network statistics, historical charts, shielded pool data, mining tools, a Unified Address decoder, calculators, games, a terminal and other applications. Behind the interface is a Next.js frontend with a Fastify, Prisma and PostgreSQL backend. It connects to Zcash node and indexing infrastructure for live blockchain data, uses Zaino or lightwalletd for light-client access, and integrates Zingo CLI for shielded ownership-verification flows.

A user begins with a human-readable Zcash name, scans a QR code and sends a small shielded authentication payment. A Rust service built with librustzcash detects the transaction and returns a deterministic one-time password through an encrypted memo. An OIDC identity broker then hides the blockchain complexity from applications, allowing developers to integrate Zcash authentication through standard OAuth-compatible libraries and frameworks.

Players jointly shuffle and encrypt the deck through a mental-poker ceremony, with shuffle proofs and per-card zero-knowledge reveals used to verify that the game remains fair. Communication passes through an encrypted relay, while funds are held in a 2-of-3 FROST shielded escrow. Settlement requires signatures from both players over the agreed outcome, preventing the operator from redirecting the pot.

CYZE provides distributed key-generation ceremonies, configurable threshold policies and rerandomized RedPallas FROST signing for shielded transactions. Participants review and approve transactions before producing their signature shares, while ceremony messages are end-to-end encrypted and the coordination server acts only as an untrusted relay. The application also includes an encrypted keystore, recovery support, group management and a PCZT-based transaction-building and signing flow.

Gómez and Micaela, Pendrake Watch is a watch-only desktop wallet for individuals and organizations that need visibility into shielded funds without holding the authority to spend them. The application imports only a Unified Full Viewing Key and uses a Zingolib-based background service to locally discover Orchard and Sapling notes, transactions and memos. It provides balance history, historical fiat valuations, transaction notifications, note-level information and a discreet mode for hiding sensitive information during screen sharing. Wallet data is encrypted at rest, while the background daemon can continue synchronizing when the main interface is closed or locked.
