Mina zkApp: Batch_Test

This repository contains code for batching transactions, either by sending multiple transactions in parallel or batching multiple transactions into one.

What's New

• o1js Patch
  A patch to export getCachedAccount from fetch.js.

• LocalContext
  A utility for updating the context after executing zkApp methods.

Usage Example

Single Method Call within a Transaction

let context = await LocalContext(zkApp.address);

let tx1 = await context.transaction(
  { sender: feepayerAddress, fee, nonce: nonce++ },
  async () => {
    let curValue = zkApp.num.get();
    await zkApp.update(curValue);
  }
);

let tx2 = await context.transaction(
  { sender: feepayerAddress, fee, nonce: nonce++ },
  async () => {
    let curValue = zkApp.num.get();
    await zkApp.update(curValue);
  }
);

Multiple Method Calls within a Transaction

let updaters = [];

for (let i = 0; i < NUM_OF_TRANSACTIONS; i++) {
  updaters.push(() => {
    let currentValue = zkApp.num.get();
    return zkApp.update(currentValue);
  });
}

const batchedTransaction = await context.batchedTransaction(
  { sender: feepayerAddress, fee, nonce: nonce++ },
  updaters
);

How to Run

1. Install dependencies:

   pnpm install

2. Configure your zkApp:

   zk config

   Make sure to create a deploy alias.

3. Deploy your zkApp:

   zk deploy <YOUR_DEPLOY_ALIAS>

4. Test the batching:

   • Test with multiple transactions sent in parallel:

     node ./build/src/interact.js <YOUR_DEPLOY_ALIAS>

   • Test with batched transactions:

     node ./build/src/interact_batched.js <YOUR_DEPLOY_ALIAS>
