Golang implementation of the PlatON protocol

Go PlatON

Welcome to the PlatON source code repository! This software is Ethereum-based and it has changed some peculiarities according the PlatON's whitepaper.

Building the source

For prerequisites and detailed build instructions please read the Installation Instructions on the Docs.

Building platon requires both a Go (version 1.7 or later) and a C compiler. You can install them using your favourite package manager. Once the dependencies are installed, run

make platon

or, to build the full suite of utilities:

make all

If you want to Building platon with MPC function, run

make platon-with-mpc

or:

make all-with-mpc

If you want to Building platon with VC function, run

make platon-with-vc

or:

make all-with-vc

Executables

The project comes with several executables found in the cmd directory.

Command	Description
platon	Our main PlatON CLI client. It is the entry point into the PlatON network
ethkey	a key related tool.

Running a platon node

Config the chain data

first, you need to get an account:

$ ./platon --datadir ./data account new
Your new account is locked with a password. Please give a password. Do not forget this password.
Passphrase:
Repeat passphrase:
Address: {566c274db7ac6d38da2b075b4ae41f4a5c481d21}

second, generate a private node's key pair and save the PrivateKey as a file named 'nodekey' into the ./data

$ ./ethkey genkeypair
Address   :  0xA9051ACCa5d9a7592056D07659f3F607923173ad
PrivateKey:  1abd1200759d4693f4510fbcf7d5caad743b11b5886dc229da6c0747061fca36
PublicKey :  8917c748513c23db46d23f531cc083d2f6001b4cc2396eb8412d73a3e4450ffc5f5235757abf9873de469498d8cf45f5bb42c215da79d59940e17fcb22dfc127

then, edit the following content and save it as json file, such as genesis.json:

{
    "config": {
    "chainId": 300,
    "homesteadBlock": 1,
    "eip150Block": 2,
    "eip150Hash": "0x0000000000000000000000000000000000000000000000000000000000000000",
    "eip155Block": 3,
    "eip158Block": 3,
    "byzantiumBlock": 4,
    "cbft": {
      "initialNodes": ["enode://8917c748513c23db46d23f531cc083d2f6001b4cc2396eb8412d73a3e4450ffc5f5235757abf9873de469498d8cf45f5bb42c215da79d59940e17fcb22dfc127@127.0.0.1:16789"]
      }
  },
  "nonce": "0x0",
  "timestamp": "0x5c074288",
  "extraData": "0x00",
  "gasLimit": "0x99947b760",
  "difficulty": "0x40000",
  "mixHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
  "coinbase": "0x0000000000000000000000000000000000000000",
  "alloc": {
    "0x566c274db7ac6d38da2b075b4ae41f4a5c481d21": {
      "balance": "999000000000000000000"
    }
  },
  "number": "0x0",
  "gasUsed": "0x0",
  "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000"
}

at last, init the chain as follow:

$ ./platon --datadir ./data init platon.json

and it will output msg as:

...
Successfully wrote genesis state

so we can launch the node:

$ ./platon --identity "platon" --datadir ./data --nodekey ./data/platon/nodekey --rpcaddr 0.0.0.0 --rpcport 6789 --rpcapi "db,eth,net,web3,admin,personal" --rpc --nodiscover

Send a transaction

> eth.sendTransaction({from:"0x566c274db7ac6d38da2b075b4ae41f4a5c481d21",to:"0x3dea985c48e82ce4023263dbb380fc5ce9de95fd",value:10,gas:88888,gasPrice:3333})
"0xa8a79933511158c2513ae3378ba780bf9bda9a12e455a7c55045469a6b856c1b"

Check the balance:

> eth.getBalance("0x3dea985c48e82ce4023263dbb380fc5ce9de95fd")
10

OK, it seems that the chain is running correctly
