zkIgnite 3: ’Sliced’ Approach to Cooperative Group Purchases

zkIgnite 3: ’Sliced’ Approach to Cooperative Group Purchases

Sliced revolutionizes financial product interactions through a three-stage process: discovery, progress, and settlement.

In the discovery stage, retailers become Group Owners (GOs), forming groups for collective purchases. Users express interest and agree on group settings, with GOs confirming and locking them in.

The progress stage involves monthly payments, allowing users to acquire two goods monthly via raffle and auction. Auction winners pay extra instalments, reducing their payment duration and benefiting the group’s liquidity.

In the settlement stage, ownership transfers from GOs to users. Groups act autonomously, making decisions via Mina’s Zero-Knowledge Proofs (ZKPs), ensuring privacy.

Proposed solutions include smart contracts for regulatory compliance and identity verification via Mina. Trustless bridges enable integration with other blockchains, offering financial flexibility. Tokenized real-world assets further enhance trustless purchases.

Users’ engagement and fulfilment build reputation, potentially granting access to exclusive groups and platform contribution privileges.

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.
