LK-Chain

Supporting golang implementation of the Ethereum protocol.

Building the source

Building lk-chain requires Go (version 1.9.2).
System Centos 7.
Install git lfs before, and then clone this project.
To build the full suite of utilities:

./build.sh all

or, to clean build path:

./build.sh clean

Executables

The LK-Chain project comes with several wrappers/executables found in the pack/lk-chain/bin directory.

Command	Description
ethermint	Ethereum protocol
tendermint	Tendermint Core is Byzantine Fault Tolerant (BFT) middleware

Running LK-Chain

Going through all the possible command line flags is out of scope here (please consult our CLI Wiki page), but we've enumerated a few common parameter combos to get you up to speed quickly on how you can run your own Ethermint and Tendermint instance.

Full node on the main LK-Chain network

# go to sbin path.
cd pack/lk-chain/sbin

# init the node data in the first time.
./start.sh init DataPath

# start the node
./start.sh start DataPath

# if you want to stop the instance
./start.sh stop

Configuration

ethermint Configuration:

• --rpcport 44000
• --lkrpc_addr 0.0.0.0:45000

tendermint Configuration:

• --rpc.laddr tcp://0.0.0.0:41000

Programatically interfacing LK-Chain nodes

The IPC interface is enabled by default and exposes all the APIs supported by Ethermint, whereas the HTTP and WS interfaces need to manually be enabled and only expose a subset of APIs due to security reasons. These can be turned on/off and configured as you'd expect.

You can use ethermint like geth console:

[root@localhost sbin]# ../bin/ethermint attach http://127.0.0.1:44000
Welcome to the Geth JavaScript console!

 modules: admin:1.0 eth:1.0 net:1.0 personal:1.0 rpc:1.0 web3:1.0

> eth.blockNumber
65719

or request a JSON-RPC API,like this:

// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_getBalance","params":["0xc94770007dda54cF92009BFF0dE90c06F603a09f", "latest"],"id":1}' -H 'Content-Type:application/json' http://127.0.0.1:44000

// Result
{
  "id":1,
  "jsonrpc": "2.0",
  "result": "0x0234c8a3397aab58" // 158972490234375000
}

Ethermint HTTP based JSON-RPC API options:

• --rpc Enable the HTTP-RPC server
• --rpcaddr HTTP-RPC server listening interface (default: "localhost")
• --rpcport HTTP-RPC server listening port (default: 8545)
• --rpcapi API's offered over the HTTP-RPC interface (default: "eth,net,web3")
• --rpccorsdomain Comma separated list of domains from which to accept cross origin requests (browser enforced)
• --ws Enable the WS-RPC server
• --wsaddr WS-RPC server listening interface (default: "localhost")
• --wsport WS-RPC server listening port (default: 8546)
• --wsapi API's offered over the WS-RPC interface (default: "eth,net,web3")
• --wsorigins Origins from which to accept websockets requests
• --ipcdisable Disable the IPC-RPC server

Find more JSON-RPC APIs on file doc/json-rpc.md.

db.Get err: leveldb: not found

root@iZ250j4nbn4Z:/mnt/appadm/lk-chain/pack/lk-chain/sbin# ./start.sh init DataPath
init ethermint ...
Fatal: failed to write genesis block: db.Get err: leveldb: not found
init tendermint ...

能帮忙看一下，这个问题 是什么原因造成的？

超级节点什么时候来？

这些代码是迅雷团队弄的还是链享云搞的。

手续费应该怎么设置，好麻烦的感觉

GasPrice和GasLimit到底应该怎么设置呀？
感觉怎么调整都有问题，做归集的时候。

在线钱包已做好，有没有开放节点的

https://lkwallet.github.io 我服务器磁盘小了，区块把空间给占满了

弱弱的问下，现在运行的节点有哪些？私有节点上？

linktoken will up 8000￥，your villa will stand by the sea!

怎么同步其它节点数据

./start.sh start DataPath
这个命令执行成功后怎么能同步其他节点的数据。有大佬能指导一下吗？

使用eth_getTransactionReceipt获取收据，成功的交易响应的"status": "0x0"

使用区块浏览器查询该交易：tx = "0x16509530a7c2046fb450ac31430cbc9c90f947757e02100c30151eb4e94f3477"

使用rpc请求钱包：

}

其中的 "status": "0x0" 按接口文档说明应该是失败的，是改用别的方法校验还是怎么操作呢，能给个提示吗

难道不像以太坊嘛！

创建本地钱包成功，但使用eth_signTransaction转账链克失败

如题，在unlock指定账号后，使用eth_signTransaction转账可以返回类似于这样的结果：
{"jsonrpc":"2.0","id":1,"result":{"raw":"0xf86e0185174876e800830186a094577cb6506b656cf92d4eef4a707c30629a5a30708716345785d8a0008082e3e6a0761e18a7e74a48708418fc7a8c5290bee87a5554cb4247e749c3230d41655e4aa023dc63311a4f24b9efda94485a803d03d109d3baf7fe0582b75c83af98a4f652","tx":{"nonce":"0x1","gasPrice":"0x174876e800","gas":"0x186a0","to":"0x577cb6506b656cf92d4eef4a707c30629a5a3070","value":"0x16345785d8a000","input":"0x","v":"0xe3e6","r":"0x761e18a7e74a48708418fc7a8c5290bee87a5554cb4247e749c3230d41655e4a","s":"0x23dc63311a4f24b9efda94485a803d03d109d3baf7fe0582b75c83af98a4f652","hash":"0xaa93424c180fe89adbfd519787dcb2a47683971795332f4812acc8d77da15aef"}}}
看似好像成功了，但很可惜查询对应的交易hash根本查不到，钱包余额也没用变动……这是咋回事呢，难道目前的节点没有转账的权限么？

照搬照抄的，创新在哪里？

我发送一次交易gas和gasPrice应该设多少？

照你们文档的来，有data字段每次都报Network is abnormal, please try again later错误。没有data字段就报illegal gasLimit or gasPrice错误

区块同步很慢，3天同步了1/10不到，有什么建议配置可以加快同步速度吗？

网络是500M应该影响不大，机器负载也比较小。同步慢是和节点少有关系吗，或者和其他因素相关，帮忙给个建议
