① 启动tendermint并检查状态

初始化tendermint

$ tendermint init

单节点方式启动tendermint，并使用内置应用kvstore。-proxy_app运行标志用来指定一个内置的ABCI应用，例如kvstore是tendermint程序内置的键值对应用。

$ tendermint node --proxy_app=kvstore
# 如果之前已经使用过tendermint，只需要初始化data就可以
$ tendermint unsafe_reset_all

查看状态

$ curl -s localhost:26657/status
{"jsonrpc": "2.0","id": "","result": {"node_info": {"protocol_version": {"p2p": "7","block": "10","app": "1"},"id": "d774d477fd4f339058d7dc35edf75f32371fc5b7","listen_addr": "tcp://0.0.0.0:26656","network": "test-chain-F5dt3c","version": "0.31.5","channels": "4020212223303800","moniker": "master","other": {"tx_index": "on","rpc_address": "tcp://0.0.0.0:26657"}},"sync_info": {"latest_block_hash": "B6B423295B7641BD540DF051F2597984784B5F93C27FE3ED053B9B75447368EC","latest_app_hash": "0000000000000000","latest_block_height": "252","latest_block_time": "2019-05-01T11:35:34.80586108Z","catching_up": false},"validator_info": {"address": "4252DFF3DD179BB27E73EBCBE0B9B706F7E7CBF9","pub_key": {"type": "tendermint/PubKeyEd25519","value": "OpVAF6IXhA7r5nF+DqgNLTvfE1TQXOuKT93yFawTA/Y="},"voting_power": "10"}}
}

② 提交交易

提交一个交易，使用curl向Tendermint节点的RPC服务发出请求。没有指定key，value，lucy会既是key，又是value。

$ curl -s 'localhost:26657/broadcast_tx_commit?tx="lucy"'
{"jsonrpc": "2.0","id": "","result": {"check_tx": {"gasWanted": "1"},"deliver_tx": {"tags": [{"key": "YXBwLmNyZWF0b3I=","value": "Q29zbW9zaGkgTmV0b3dva28="},{"key": "YXBwLmtleQ==","value": "bHVjeQ=="}]},"hash": "DC99E9AA86FAB83A062CFF5E0808391757071A3D5DBB942802D5F923AAEAD3B4","height": "299"}
}

返回的 Response 中的 key 和 value 使用了 base64 进行了编码，例如，结果中的value字段，例如bHVjeQ==，这其实是字符串lucy的base64编码。我们可以通过命令 base64 对其进行解码，结论：可以发现key = lucy

$ echo "YXBwLmNyZWF0b3I=" | base64 -d
app.creator
$ echo "Q29zbW9zaGkgTmV0b3dva28=" | base64 -d
Cosmoshi Netowoko
$ echo "YXBwLmtleQ==" | base64 -d
app.key
$ echo "bHVjeQ==" | base64 -d
lucy

也可以指定key和value，提交一个交易：

$ curl -s 'localhost:26657/broadcast_tx_commit?tx="name=tiger"'
{"jsonrpc": "2.0","id": "","result": {"check_tx": {"gasWanted": "1"},"deliver_tx": {"tags": [{"key": "YXBwLmNyZWF0b3I=","value": "Q29zbW9zaGkgTmV0b3dva28="},{"key": "YXBwLmtleQ==","value": "bmFtZQ=="}]},"hash": "EC6087612FF50A1BF5353EF0F7F344F33EDCCFD511939EE063DD4840E599795D","height": "620"}
}
$ echo "bmFtZQ==" | base64 -d'
name

③ 查询交易

查询第一个交易，该交易没有指定key，key和value均为lucy:

$ curl -s 'localhost:26657/abci_query?data="lucy"'
{"jsonrpc": "2.0","id": "","result": {"response": {"log": "exists","key": "bHVjeQ==","value": "bHVjeQ=="}}
}
$ echo "bHVjeQ==" | base64 -d
lucy

查询第二个交易，key为name，value为tiger：

$ curl -s 'localhost:26657/abci_query?data="name"'
{"jsonrpc": "2.0","id": "","result": {"response": {"log": "exists","key": "bmFtZQ==","value": "dGlnZXI="}}
}
$ echo "bmFtZQ==" | base64 -d
name
$ echo "dGlnZXI=" | base64 -d'
tiger
