## Basic types

### ClientVersionResponse

```proto
message ClientVersionResponse {
    string version = 1; // 节点客户端版本
}
```

### TransactionType

```proto
enum TransactionType {
  RECORD = 0; // 通用数据记录
  MESSAGE = 1; // 消息
  CONTRACT_CREATION = 2; // 合约创建
  CONTRACT_INVOCATION = 3; // 合约调用
}
```

### Transaction

```proto
message Transaction {
  uint64 block_number = 1; // 事务所在的区块的区块号，当事务处于待确认状态时为`null`
  bytes block_hash = 2; // 事务所在的区块的哈希，当事务处于待确认状态时为`null`
  uint32 index = 3; // 事务在区块中的位置index，当事务处于待确认状态时为`null`
  bytes hash = 4; // 事务的哈希
  TransactionType type = 5; // 事务类型
  bytes from = 6; // 发送账户地址
  uint64 nonce = 7; // 这条事务之前发送者所发送的事务数量
  bytes to = 8; // 接收账户地址，或者调用的合约地址，或者`null`如为合约创建
  bytes data = 9; // 数据或合约代码
  bytes v = 10; // ECDSA recovery id
  bytes r = 11; // ECDSA signature r
  bytes s = 12; // ECDSA signature s
}
```

### Block

```proto
message Block {
  uint64 number = 1; // 区块号，当区块处于待确认状态时为`null`
  bytes hash = 2; // 区块的哈希，当区块处于待确认状态时为`null`
  bytes parent_hash = 3; // 父区块的哈希
  bytes witness = 4; // 见证者账户地址
  uint64 timestamp = 5; // 区块产生时的UNIX时间戳
  uint64 size = 6; // 区块大小的字节数
  bytes transactions_root = 7; // 区块的事务树根
  repeated Transaction transactions = 8; // 事务对象的数组，或为空
  repeated bytes transaction_hashes = 9; // 32字节的交易哈希的数组，或为空
}
```
