Technical Approach: Dive into the how of your project. Describe your approaches, components, workflows, methodology, etc. Bullet points and diagrams are appreciated!
Here’s a detailed technical approach for “Zcash on the Go”:

  1. Architecture Overview:

    • The mobile wallet applications will follow a client-server architecture.
    • Client-side: The mobile app interface for users to interact with their Zcash funds.
    • Server-side: Backend infrastructure to handle wallet synchronization, transaction broadcasting, and other network interactions.
  2. Components:

    • Mobile Wallet Interface: User-friendly interface for managing Zcash funds, including sending, receiving, and viewing transaction history.
    • Zcash Protocol Integration: Integration with the Zcash network to facilitate transactions and ensure wallet compatibility with the Zcash blockchain.
    • Encryption and Security: Implementation of encryption algorithms and security measures to protect user data and private keys.
    • Network Connectivity: Integration with mobile device APIs to handle network connections, including support for low bandwidth environments.
    • User Authentication: Implementation of authentication mechanisms to secure access to the mobile wallet application.
    • Backend Services: Server-side infrastructure to support wallet functionality, including transaction processing and network communication.
  3. Workflow:

    • User Registration: Users will download the mobile wallet app from the app store and create an account by providing necessary information.
    • Wallet Initialization: Upon account creation, the wallet will be initialized, and a new Zcash address will be generated for the user.
    • Funding the Wallet: Users can fund their wallets by receiving Zcash from other users or purchasing Zcash from exchanges.
    • Transaction Execution: Users can initiate transactions by specifying the recipient’s address and the amount to send. The wallet app will handle transaction creation, signing, and broadcasting to the Zcash network.
    • Transaction Confirmation: Once a transaction is broadcasted, users can track its progress through the app and receive confirmations once it’s included in a block on the Zcash blockchain.
    • Security Measures: The mobile wallet app will incorporate security features such as PIN or biometric authentication, encryption of sensitive data, and backup and recovery options for private keys.
  4. Methodology:

    • Agile Development: Adopting agile development methodologies to iterate quickly, respond to user feedback, and adapt to changing requirements.
    • Continuous Integration and Deployment (CI/CD): Implementing CI/CD pipelines to automate testing, deployment, and delivery of updates to the mobile wallet applications.
    • User-Centric Design: Prioritizing user experience and usability in the design and development process, with regular usability testing and feedback loops.

Mobile Wallet Application: The client-side component installed on users’ mobile devices. It provides a user interface for users to interact with their Zcash funds, initiate transactions, and view transaction history.
Backend Infrastructure: The server-side component responsible for supporting wallet functionality, including wallet synchronization, transaction processing, and network communication with the Zcash blockchain.
Zcash Network (Blockchain): The decentralized network of nodes running the Zcash protocol. It processes and validates transactions, maintains the blockchain ledger, and ensures the integrity and security of the Zcash network.
User Interface (Mobile App): The graphical user interface provided by the mobile wallet application. It allows users to input transaction details, view wallet balances, and receive status updates on transactions.

  • Transaction Workflow Diagram
    | Start Transaction |
    | Enter Transaction Details |
    | Confirm Transaction |
    | Generate Transaction |
    | (Sign Transaction) |
    | Broadcast Transaction |
    | (Send to Zcash Network) |
    | Transaction Processing |
    | (Verify, Include in Block) |
    | Transaction Confirmed |

Start Transaction: Initiates the transaction process within the mobile wallet application.
Enter Transaction Details: User inputs recipient address, amount, and any additional transaction details.
Confirm Transaction: User confirms the transaction details before proceeding.
Generate Transaction (Sign Transaction): The wallet app generates a transaction and signs it with the user’s private key to authorize the transfer.
Broadcast Transaction (Send to Zcash Network): The signed transaction is broadcasted to the Zcash network to be included in a block.
Transaction Processing (Verify, Include in Block): Miners on the Zcash network verify and process the transaction, including adding it to the blockchain.
Transaction Confirmed: Once the transaction is included in a block and receives sufficient confirmations, it is considered confirmed, and the recipient receives the Zcash.
By following this technical approach, “Zcash on the Go” aims to deliver robust, secure, and user-friendly mobile wallet applications that enable individuals and businesses in Africa to access, manage, and transact with Zcash securely and conveniently.

Hi @Ghedosa - Thank you for submitting your second grant proposal! We will review it in the upcoming weeks and reach out if we have any questions.

In the meantime, if you have any questions for us, you can post them to this thread or DM us at @ZcashGrants.

Zcash Community - We want to hear your feedback on this grant! You can post your comments to this thread or DM us at @ZcashGrants if you’d like to provide feedback in private.


i think we got a few well working wallets now/soon, and i don’t think that someone not familiar with the protocol should be given that much money for building another one! why not use the wallets that already exist? @Ghedosa

Also Milestone 1 is looking pretty expensive to me, compared to what will be delivered.
What if this project never gets to Milestone 2?

most of this and the other grant application was written by AI (including the website), nothing wrong with that, but something that we should keep in mind.


@Ghedosa Thank you for your submission. After consideration from @ZcashGrants and sufficient time for the community to provide feedback on the forum, the committee has decided to reject this proposal. There is no need for new wallet projects at this time.

The committee appreciates your grant submission efforts and encourages you to continue as an active member of the Zcash community going forward, both here on the forum and in the below avenues as well:
