篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Mina Berkeley QANet测试网zkApp初体验相关的知识，希望对你有一定的参考价值。
1. 引言
Mina系列博客有：
- Mina概览
- Mina的支付流程
- Mina的zkApp
- Mina中的Pasta（Pallas和Vesta）曲线
- Mina中的Schnorr signature
- Mina中的Pickles SNARK
- Mina中的Kimchi SNARK
- Mina Kimchi SNARK 代码解析
Ubuntu 18.04：
$ echo "deb [trusted=yes] http://packages.o1test.net $(lsb_release -cs) unstable" | sudo tee /etc/apt/sources.list.d/mina-unstable.list
$ sudo apt-get update
# 安装Mina daemon
$ sudo apt-get install -y mina-berkeley=1.3.0beta1-release-2.0.0-ba9a0e0
# 安装Mina zkApp test transaction CLI
$ sudo apt-get install -y mina-snapp-test-transaction=1.3.0beta1-release-2.0.0-ba9a0e0
启动节点连接QANet测试网：
$ mina daemon --peer-list-url https://storage.googleapis.com/seed-lists/berkeley_seeds.txt
等待数分钟启动完毕后，确认所连接的网络正确：
$ mina client status
若为QANet，输出对应信息应有：
Chain id: da081e702d0e02be30a7351bc2a54898593bb67934b46809400af4c890d13c89
Git SHA-1: ba9a0e088b73a3c389550ee002ef0afc1ce3976d
同时mina client status输出信息中还包含了节点连接状态信息：
Peers: 12
User_commands sent: 0
SNARK worker: None
SNARK work fee: 100000000
Sync status: Catchup
Sync status有3种状态：
- 1）Bootstrap：表示节点在启动中，需要与网络同步。【若该状态持续超过1小时，说明端口配置有误。】
- 2）Catchup：表示正在收集最新的区块和状态，以跟上最新区块。
- 3）Synced：且连接了1个或多个节点，表示已与网络成功连接，同时会看到日志
[Info] Mina daemon is now synced。
通过mina-generate-keypair离线生成key-pair文件：【若离线创建，需调用mina accounts import --privkey-path ~/.mina-config/wallets/store/B62qnHtHCf5ZJcwU5RqPCjZ31uFhSUSq8oHfxEVqMLC3JsxJFMxt3YS 导入账号。】【用作zkApp account】
$ mkdir ~/keys
$ chmod 700 ~/keys
$ mina-generate-keypair --privkey-path ~/keys/my-wallet
Password for new private key file:
Again to confirm:
Keypair generated
Public key: B62qpbnWwNdhjdmTCfLJMbJXnYDDqxdRNv2Hm7Be9pnLudF5vn7QTs1
Raw public key: B76070918E0322861C708B130CDC05E0BC76342D29F81D0C4B5765C17396959D
或与节点交互使用mina accounts create生成账号：【用作fee payer】
$ mina accounts create
验证生成的账号公私钥匹配正确：
$ mina-validate-keypair --privkey-path ~/.mina-config/wallets/store/B62qnHtHCf5ZJcwU5RqPCjZ31uFhSUSq8oHfxEVqMLC3JsxJFMxt3YS
Enter password:
Again to confirm:
Public key on-disk is derivable from private key
Verified a transaction using specified keypair
获取测试token faucet为：
查看账号balance：
$ mina accounts list
Account #1:
Public key: B62qnHtHCf5ZJcwU5RqPCjZ31uFhSUSq8oHfxEVqMLC3JsxJFMxt3YS
Balance: 9
Locked: false
在浏览器中输入localhost:3085/graphql可查看数据库信息。
主要测试点为：
1. Sync to the network with/without empty config directory
2. Successfully able to bootstrap to the latest state after restart
3. Create snapp accounts (using the new Snapps Test Transaction CLI)
4. Update various account fields using snapp transactions (using the new Snapps Test Transaction CLI)
5. Create non-snapp accounts using snapp transactions (using the new Snapps Test Transaction CLI)
6. Invalid transactions should be rejected (Some of the errors are insufficient funds, insufficient fees, insufficient replace fees, invalid sigantures, invalid proof, duplicates, and invalid nonce )
7. Valid transactions (snapp transactions or payments or delegations) should be added to the pool and included in a block
8. Snark work is added to the pool and included in blocks
9. Community block producers are producing blocks
10. Run archive nodes and verify that transactions (snapp transactions or otherwise) are archived
2. QANet zkApp
2.1 创建zkApp account
创建zkApp account并默认部署了一个测试合约：【等待一下】
$ mina-snapp-test-transaction create-snapp-account --fee-payer-key ~/.mina-config/wallets/store/B62qnHtHCf5ZJcwU5RqPCjZ31uFhSUSq8oHfxEVqMLC3JsxJFMxt3YS --nonce 0 --receiver-amount 2 --snapp-account-key ~/keys/my-wallet
