查询本地节点及链上部分数据的基本信息

1. 获取当前区块链的信息

获取当前区块链的信息。使用方式 cleos get info [OPTIONS]。

$ cleos get info
{
  "server_version": "2da868b3",
  "chain_id": "aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906",

  "virtual_block_net_limit": 1048576000,
  "block_cpu_limit": 200000,
  "block_net_limit": 1048576,
  "server_version_string": "v2.0.1"
}

2. 查询指定区块的信息

2.1 通过区块高度查询

$ cleos get block 1
{
  "timestamp": "2018-06-08T08:08:08.500",
  "producer": "",
  "confirmed": 1,
  "previous": "0000000000000000000000000000000000000000000000000000000000000000",
  "transaction_mroot": "0000000000000000000000000000000000000000000000000000000000000000",
  "action_mroot": "aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906",
  "schedule_version": 0,
  "new_producers": null,
  "header_extensions": [],
  "producer_signature": "SIG_K1_111111111111111111111111111111111111111111111111111111111111111116uk5ne",
  "transactions": [],
  "block_extensions": [],
  "id": "00000001405147477ab2f5f51cda427b638191c66d2c59aa392d5c2c98076cb0",
  "block_num": 1,
  "ref_block_prefix": 4126519930
}

其中：

1 表示区块编号或高度

2.2 通过区块哈希查询

$ cleos get block 00000001405147477ab2f5f51cda427b638191c66d2c59aa392d5c2c98076cb0{
  "timestamp": "2018-06-08T08:08:08.500",
  "producer": "",
  "confirmed": 1,
  "previous": "0000000000000000000000000000000000000000000000000000000000000000",
  "transaction_mroot": "0000000000000000000000000000000000000000000000000000000000000000",
  "action_mroot": "aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906",
  "schedule_version": 0,
  "new_producers": null,
  "header_extensions": [],
  "producer_signature": "SIG_K1_111111111111111111111111111111111111111111111111111111111111111116uk5ne",
  "transactions": [],
  "block_extensions": [],
  "id": "00000001405147477ab2f5f51cda427b638191c66d2c59aa392d5c2c98076cb0",
  "block_num": 1,
  "ref_block_prefix": 4126519930
}

其中：

00000001405147477ab2f5f51cda427b638191c66d2c59aa392d5c2c98076cb0 表示区块的 hash 值

2.3 查询区块头状态

$ cleos get block 1 --header-state

3. 获取验证人信息

获取验证人列表。使用方式 cleos get schedule [OPTIONS]。
