zkIgnite 3: ZK-SMART-NFC

TrustChain, a developer protocol, endeavors to address issues of anti-counterfeiting, document security, and inefficient off-chain payments using blockchain technology. Their primary offering, ZK Smart NFC, integrates secure NFC technology with the Mina Protocol blockchain to provide innovative and secure solutions across various industries.

Counterfeiting and document fraud pose significant challenges in industries such as fashion, food and beverage, and electronics, leading to revenue losses and consumer safety concerns. Traditional payment methods also suffer from slow processing times and high transaction fees.

TrustChain’s proposed solution leverages ZK Smart NFC technology to combat counterfeiting and document fraud while improving payment efficiency. By integrating NFC technology with the Mina Protocol blockchain, TrustChain establishes a secure and immutable ledger for data verification. The NFC chip contains a secure private key inaccessible to external parties, and NFC data is encoded and stored in the Merkle Tree. The root hash of the Merkle Tree is then saved in a smart contract, ensuring data integrity and security.

Mina Navigators is poised to establish a groundbreaking standard for ZK developer engagement, urging innovators to embark on the journey of creating, refining, and contributing to the Mina ecosystem.


There are three distinct phases within the Navigator program:

  1. Hackathon: October 9 through November 10
  2. Learn-to-earn challenges: November 2023 through April 2024
  3. Final contribution grant: April 30, 2024
Phase One

In Phase One, known as The Navigators Hackathon, commencing on October 9th, a five-week hackathon unfolds. Outstanding submissions during this period stand a chance to receive MINA token grants and a coveted 'Navigator' badge—a symbol of acceptance into the Navigators program. Those adorned with the badge qualify for Phase Two, engaging in monthly challenges to accrue grants.

Developers are tasked with constructing functional and efficient proof-of-concept applications and tooling for Mina. This endeavor aims to spotlight their ingenuity and technical prowess across diverse use cases on the Mina platform.

Judging involves a panel of seven individuals from the Mina ecosystem. For more comprehensive information regarding grants, submission criteria, and the judging process, the Navigators hub offers detailed insights.

Phase Two

In Phase Two, the Navigators embark on the Build and Learn-to-Earn journey (or, as they humorously term it, Navigate-to-Earn). This marks the initiation of the enjoyable phase. Post-hackathon, Navigators engage in collaborative efforts, either on their personal projects or those of their peers from the hackathon. Their active participation in a 6-month series of challenges positions them to earn monthly grants, facilitating an accelerated learning experience on ZK, Mina, and o1js.

Phase Three

As Phase Three unfolds, the Navigators, having invested six months of unwavering dedication and hard work, seize the opportunity to present their contributions. A panel of community electors becomes the discerning audience, evaluating these endeavors for the coveted grand prizes of MINA grants. Notably, these prizes distinguish themselves by being non-project-specific, emphasizing individual contributions spread across various projects and GitHub repositories.
