用了 Local.incrementGlobalSlot() 之后，app 里面的 this.network.blockchainLength.get() 还是 0

合约代码：

import { SmartContract, DeployArgs, Permissions, method, Provable } from 'o1js';

export class mytest extends SmartContract {
  async deploy(props?: DeployArgs) {
    await super.deploy(props);

    this.account.permissions.set({
      ...Permissions.default(),
      setVerificationKey:
        Permissions.VerificationKey.impossibleDuringCurrentVersion(),
      setPermissions: Permissions.impossible(),
    });
  }

  @method async test() {
    const currentBlock = this.network.blockchainLength.get();
    this.network.blockchainLength.requireEquals(currentBlock);
    Provable.log('Current Block is', currentBlock);
  }
}

测试代码：

import { Mina, UInt32, UInt64, AccountUpdate } from 'o1js';
import { getProfiler } from './utils/profiler.js';
import { mytest } from './myContract.js';

const mytestProfiler = getProfiler('mytest zkApp');
mytestProfiler.start('mytest zkApp test flow');

const doProofs = false;
let Local = await Mina.LocalBlockchain({ proofsEnabled: doProofs });
Mina.setActiveInstance(Local);

// Compile contract
if (doProofs) {
  await mytest.compile();
} else {
  await mytest.analyzeMethods();
}

// Test account setup
let [deployer] = Local.testAccounts;

let zkappAccount = Mina.TestPublicKey.random();
let zkapp = new mytest(zkappAccount);

console.log('Deploying mytest contract...');
let deployTx = await Mina.transaction(
  { sender: deployer, fee: 0.1 * 1e9, memo: 'Deploy CrowdFunding Contract' },
  async () => {
    AccountUpdate.fundNewAccount(deployer); // Fund the zkApp account

    await zkapp.deploy(); // Deploy the zkApp
  }
);
await deployTx.prove();
await deployTx.sign([deployer.key, zkappAccount.key]).send();

console.log('Contract deployed.');
console.log('\n');
console.log('Initial state:');
console.log(
  'Current block height :',
  Local.getNetworkState().globalSlotSinceGenesis.toString()
);

console.log('\n');
console.log('Simulating end of funding period...');
Local.incrementGlobalSlot(101);
console.log(
  'Current block height:',
  Local.getNetworkState().globalSlotSinceGenesis.toString()
);

console.log('\n');
console.log('Call test function ...');
let testTx = await Mina.transaction(
  { sender: deployer, fee: 0.1 * 1e9, memo: 'Test' },
  async () => {
    await zkapp.test();
  }
);
await testTx.prove();
await testTx.sign([deployer.key]).send();

mytestProfiler.stop().store();

在LocalBlockchain的本地测试中，通过Local.setBlockchainLength( 888 )来改变 区块高度。

对于LocalBlockchain对象，修改GlobalSlot和BlockchainLength 是独立的。
