应用

CITA 已经在多个实际应用场景中得到了验证，并受到了广泛的关注和采用；

获取区块信息

https://docs.citahub.com/zh-CN/cita/rpc-guide/rpc 

# 获取当前区块高度
curl -X POST --data '{"jsonrpc":"2.0","method":"blockNumber","params":[],"id":1}' 127.0.0.1:1337 | jq

# 获取区块信息
curl -X POST --data '{"jsonrpc":"2.0","method":"getBlockByNumber","params":["0xF9", true],"id":1}' 127.0.0.1:1337 | jq

删除共识节点

CITA/ 节点管理 / 共识节点管理

获取当前的共识节点列表： 

# cita-cli scm NodeManager listNode --url http://127.0.0.1:1337
{
  "id": 1,
  "jsonrpc": "2.0",
  "result": "0x0000000000000000000000000...973332f1f85ae1e2e75e"
}

发送交易，以删除共识节点（节点将被降为只读节点）： 

# cita-cli scm NodeManager deleteNode \
    --address 0x59a316df602568957f47973332f1f85ae1e2e75e \
    --admin-private 0x5f0258a4778057a8a7d97809bd209055b2fbafa654ce7d31ec7191066b9225e6 \
    --url http://127.0.0.1:1337
{
  "id": 3,
  "jsonrpc": "2.0",
  "result": {
    "hash": "0x01a4eac643589780090d5ed9fa1ac56d139776dd79ebc74a6414594d4d607393",
    "status": "OK"
  }
}

查看交易回执信息： 

# cita-cli rpc getTransactionReceipt \
    --hash 0x01a4eac643589780090d5ed9fa1ac56d139776dd79ebc74a6414594d4d607393 \
    --url http://127.0.0.1:1337

查看当前的共识节点数： 

# cita-cli scm NodeManager listNode --url http://127.0.0.1:1337
{
  "id": 1,
  "jsonrpc": "2.0",
  "result": "0x000000000000000000000000...f602568957f47973332f1f85ae1e2e75e"
}

修改链 Operator 信息

scm SysConfig setOperator \
        --operator "cita" \
        --admin-private 0x3ef2627393529fed043c7dbfd9358a4ae47a88a59949b07e7631722fd6959002

rpc getTransactionReceipt --hash 0xffc216326945016e13b4b28be6723a09a3685997ac4f20a5b3695ad04e7513e9

rpc getMetaData

获取创世区块

curl -X POST --data '{"jsonrpc":"2.0","method":"blockNumber","params":[],"id":83}' \
    127.0.0.1:1337

# 获取创世区块 https://docs.citahub.com/zh-CN/cita/rpc-guide/rpc#getblockbynumber

curl -X POST --data '{"jsonrpc":"2.0","method":"getBlockByNumber","params":["0xF9", true],"id":1}' 127.0.0.1:1337 | jq

scripts/upgrade/allowance-to-v1.4.sh 0x3ef2627393529fed043c7dbfd9358a4ae47a88a59949b07e7631722fd6959002 http://127.0.0.1:1337 secp256k1 0x4b5ae4567ad5d9fb92bc9afd6a657e6fa13a2523 127.0.0.1:4000
