结项报告详情 / Detailed Final Report

1. 项目背景 / Project Background

Quantum Purse 项目在申请星火计划资助前，已在 Nervos Foundation 的支持下，完成了一个具备核心功能的抗量子钱包原型。该原型已实现了密钥生成、签名、资产收发以及一个基于 Web 的演示界面。

为进一步提升其实用性并扩大用户范围，开发者 Tea 于 2025 年 5 月 8 日申请了星火计划资助，专注于实现两大关键扩展功能：1) 集成 Nervos DAO 功能；2) 使用 Electron 将其打包为原生桌面应用。 项目因其清晰的目标、明确的生态价值和开发者已有的坚实基础，于 2025 年 5 月 14 日获得星火计划 700 美元等值 CKB 的资助批准。
Before applying for the Spark Program grant, the Quantum Purse project had already developed a functional quantum-resistant wallet prototype with the support of the Nervos Foundation. This prototype included core features such as key generation, signing, asset transfers, and a web-based demo interface.

To further enhance its utility and broaden its user base, the developer, Tea, applied for a Spark Program grant on May 8, 2025, focusing on two key extension features: 1) Integrating Nervos DAO functionality; and 2) Packaging it as a native desktop application using Electron. The project was approved for a grant equivalent to $700 USD in CKB on May 14, 2025, thanks to its clear objectives, distinct ecosystem value, and the developer’s solid existing foundation.

2. 交付成果与完成度评估 / Deliverables & Completion Assessment

Hey @zz_tovarishch, great to see @Tung_Pham work come to fruition so fast :partying_face:

Tea’s work is a great showcase for L1 flexibility now and especially in a few years when the quantum threat will become real, so I’d say that this project is crucial for us all.

That said, I have seen way too many project being built on L1, for being abandoned just a few months later. This can also impact user adoption: how can I adopt a wallet that in a few months may not be here?

Not only that, this kind of applications need constant up-keeping due to the underlying Typescript code-base, which as we all know moves pretty fast and new vulnerabilities in third parties are discovered every day.

In short, it’s crucial to make sure that Tea has been given an economical path for long term maintenance.

Given all this, I was wondering: what kind of assurances can we make for the long term economical sustainability of the Quantum Purse?

Love & Peace, Phroi

Hi @Phroi,

Thank you for raising such a thoughtful and important question. I completely agree with you: the long-term sustainability and maintenance of a key infrastructure project, especially one as forward-thinking as Quantum Purse, are crucial for the health of the ecosystem and user trust.

I’d like to take this opportunity to first clarify the core purpose of the Spark Program. The Spark Program is designed to be a fast, lightweight, early-stage booster. Its goal is to help developers like Tea quickly validate an idea, iterate on a prototype, or complete a key feature extension within a 1-2 month timeframe. It’s meant to lower the initial barrier to innovation and let a “spark” ignite, rather than to fund a mature product that requires long-term, continuous maintenance.

From this perspective, Tea’s project is a perfect example. Building on his existing work, he used the Spark grant to efficiently achieve his stated goals (DAO functionality and a desktop app) and iterated multiple times based on community feedback, ultimately delivering a high-quality, usable product. This is exactly the outcome the Spark Program aims to foster.

Now that the project has successfully graduated from the “spark” phase, the question you’ve raised, “What’s next?” becomes critically important.

I believe that discussing the project’s long-term sustainability is an excellent topic for the entire community to engage in now. For example, from my own perspective, I’m interested in:

  • What features could make Quantum Purse even more valuable, potentially creating a path to self-sustainability?
  • In what ways can the community support its long-term maintenance?
  • Are there other projects that could integrate with Quantum Purse for mutual benefit?

I figure these discussions and suggestions could help Tea better shape his next steps.

Thank you again for your insightful feedback. This is precisely the kind of deep thinking that drives the ecosystem forward, and it’s exactly what the community hopes to see.

I would like to express my agreement with the long-term vision. However, I must respectfully disagree in the short and medium term:

  • Has the well-known JoyID wallet achieved sustainability?
  • What are the expectations for this wallet to attain sustainability?
  • Could you suggest potential ideas for achieving this?

Having navigated a similar path with iCKB, I believe that, given the current number of active users on Layer 1, the likelihood of achieving sustainability is exceedingly low. This is why many closed-source projects often seek substantial profits and exit shortly after realizing that sustainability is not feasible at this time.

I believe that CommunityDAO is a viable option. @Tung_Pham, your demonstrated ability to work effectively within the Nervos Layer 1 ecosystem is commendable. The EcoFund Spark program has provided you with initial funding and opportunities to commence your efforts. I kindly urge you to pursue a formal grant from CommunityDAO while your contributions remain fresh in the community’s memory.

I am confident that the EcoFund would support such a grant.

I would be interested in exploring integration possibilities once I have completed my work with iCKB.

Love & Peace, Phroi

@phroi I think there’s a misunderstanding here as I’m fully supported by the Nervos foundation for Quantum Purse project both financially and technically. That doesn’t stand a chance of stopping me from feeling thankful for your voice in this matter, though. You’re a rare and an important figure in the CKB community and this again proves it.

Though this Spark Program grant is modest, it catalyzed the project in a way that I believe couldn’t have been done better without it. Things could have turned out differently if I did not join. Thank you @zz_tovarishch for you and your team’s supports along the way and the detailed report. I’m flattered!

Before the time of the funding from the Nervos foundation, 2 people donated me too. Let me take this chance to send my thanks to you. I don’t know who you are but if you find this message, please know that you directly supported it. I didn’t have a chance to make all these clear from the beginning. Hopefully I’ll do better next time.

Note that this project has also been audited by Cryptape internally where some of the major technical decisions was made. If I ever go for the community fund DAO for Quantum Purse, it’d be for and external audit when it’s ready.
