Spark Program | HashThis Project Announcement
The Spark Program is dedicated to supporting community developers and innovative projects. After a review process, we are pleased to announce that the grant application for the HashThis project has been approved.
Project and developer information
• Project name: HashThis (CKB-based data integrity verification dApp)
• Developers/Team:
oïclid (@oiclidoiclidoiclidoiclidoiclidoiclidoiclidoiclid on Discord) (Years of experience in distributed systems)
shaaibu (blockchain developer)
Paul (senior smart contract engineer)
• Project overview: HashThis is a lightweight dApp designed to prove that data existed at a specific point in time and has not been tampered with. Users hash data locally and anchor the hash to the CKB chain, after which integrity and timestamp verification can be performed. The project follows Web5 principles, ensuring data is fully controlled by the user, with CKB serving only as a decentralized verification and timestamping layer.
Spark Program funding decision and rationale
The Spark Program committee has decided to provide funding equivalent to $500 (to support initial prototype development). The project is expected to be completed within 8 weeks.
The main reasons for this decision are as follows：
Ecological value and technical demonstration
The project demonstrates CKB’s potential as a neutral data integrity settlement layer, aligns with Web5 principles, and provides developers with easily reusable examples.
Practical delivery scope
The project has clear goals and focuses on the core flow of “hash → anchor → verify.” Its deliverables include an open-source codebase, a testnet prototype, and demo videos, making it well suited as a seed project supported by the Spark Program.
Experienced team
The development team has a strong background in distributed systems, blockchain tooling, and smart contract development.
Fund management and project transparency
To ensure the Starfire Program’s openness and transparency, all grant funds will be managed and disbursed through a dedicated multisig wallet. Project progress, fund usage, and final deliverables will be published through official channels.
• Project multisig wallet address:

• Multisig administrators:
This wallet uses a 2/3 multisig scheme and is jointly managed by the following project committee members to ensure fund security and proper use: Devrel Lead Hanssen, Research Lead Zhouzhou, Devrel member Yixiu.
• Fund disbursement disclosure:
Detailed information and transaction hashes for all fund disbursements (including the initial 20% startup funds and subsequent payments) will be published on the Spark Dashboard, Nervos Talk forum, and the relevant channels of the Discord community.
• Communication channels:
The discussion thread for this project within the Nervos Talk post “Spark Program | Hash This Project” will serve as one of the main public channels for communicating and updating project progress, to promote open information sharing.
Support and outlook
We look forward to HashThis successfully validating CKB’s use cases in the field of data integrity and providing the ecosystem with a valuable open-source example.
The Spark Program will provide the project with necessary support, including regular weekly sync meetings, technical mentoring, and post-completion publicity.

星火计划 | Hash This 项目公示
星火计划致力于支持社区开发者和创新项目。经过评审流程，我们高兴地宣布，对 HashThis 项目的资助申请已获批准。
项目与开发者信息
**• 项目名称：**HashThis（基于 CKB 的数据完整性验证 dApp）
• 开发者/团队：
oïclid（@oiclid _ on Discord）（多年分布式系统经验）
shaaibu（区块链开发者）
Paul（资深智能合约工程师）
**• 项目简介：**HashThis 是一款轻量级 dApp，旨在证明数据在特定时间点已存在且未被篡改。用户在本地对数据进行哈希处理，并将哈希值锚定到 CKB 链上，随后可进行完整性与时间戳验证。该项目遵循 Web5 原则，确保数据完全由用户控制，CKB 仅作为去中心化的验证与时间戳层。
星火计划资助决定及理由
星火计划委员会决定提供 500 美元 等值的资助（用于支持初始原型开发），项目预计将在 8 周 内完成。
该决定的主要理由如下：
-
**生态价值与技术展示：**该项目展示了 CKB 作为中立数据完整性结算层的潜力，符合 Web5 理念，并为开发者提供了易于复用的示例。
-
**务实的交付范围：**项目目标明确，专注于“哈希 → 锚定 → 验证”的核心流程。其交付物包括开源代码库、测试网原型及演示视频，非常适合作为星火计划支持的种子项目。
-
**团队经验丰富：**开发团队在分布式系统、区块链工具及智能合约开发方面拥有深厚的背景。
资金管理与项目透明度
为确保星火计划的公开透明，所有资助资金都将通过一个专用的多签钱包进行管理和拨付。项目的进展、资金使用情况及最终成果都将在官方渠道公示。
