Go PlatON
Welcome to the PlatON-Go source code repository! This is an Ethereum-based、high-performance and high-security implementation of the PlatON protocol. Most of peculiarities according the PlatON's whitepaper(English|中文) has been developed.
Building the source
The requirements to build PlatON-Go are:
'cmake' and 'gcc&g++' are usually built-in with Ubuntu
In addition, the following libraries needs to be installed manually
sudo apt install libgmp-dev libssl-dev
Then, clone the repository
git clone https://github.com/PlatONnetwork/PlatON-Go.git --recursive
Switch to the PlatON-Go repository root directory.
Ubuntu:
make all
Windows:
go run build\ci.go install
The resulting binary will be placed in '$PlatON-Go/build/bin'(Ubuntu) or in '%GOPATH%\bin'(Windows) .
Getting Started
The project comes with several executables found in the build/bin directory.
| Command | Description |
|---|---|
platon |
Our main PlatON CLI client. It is the entry point into the PlatON network |
keytool |
a key related tool. |
Generate the keys
Each node requires two pairs of public&private keys, the one is called node's keypair, it's generated based on the secp256k1 curve for marking the node identity and signning the block, and the other is called node's blskeypair, it's based on the BLS_12_381 curve and is used for consensus verifing. These two pairs of public-private key need to be generated by the keytool tool.
Switch to the directory where contains 'keytool.exe'(Windows) or 'keytool'(Ubuntu). Node's keypair(Ubuntu for example):
keytool genkeypair
Address : 0xA9051ACCa5d9a7592056D07659f3F607923173ad
PrivateKey: 1abd1200759d4693f4510fbcf7d5caad743b11b5886dc229da6c0747061fca36
PublicKey : 8917c748513c23db46d23f531cc083d2f6001b4cc2396eb8412d73a3e4450ffc5f5235757abf9873de469498d8cf45f5bb42c215da79d59940e17fcb22dfc127
Node's blskeypair:：
keytool genblskeypair
PrivateKey: 7747ec6876bbf8ca0934f05e45917b4213afc5814639355868bbf06d0b3e0f19
PublicKey : e5eb9915ed2b5fd52cf5ff760873a75a8562956e176968f3cbe5ea2b22e03a7b5efc07fdd5ad66d433b404cb880b560bed6295fa79f8fa649588be02231de2e70a782751dc28dbf516b7bb5d52053b5cdf985d8961a5baafa467e8dda55fe981
Note: The PublicKey generated by the 'genkeypair' command is the NodeID we needed, the PrivateKey is the corresponding node private key, and the PublicKey generated by the 'genblskeypair' command is the node BLS PublicKey, used in the staking and consensus process, PrivateKey is the Node BLS PrivateKey, these two keypairs are common in different operating systems, that is, the public and private keys generated in Windows above, can be used in Ubuntu.
store the two private keys in files:
mkdir -p ./data
touch ./data/nodekey
echo "{your-nodekey}" > ./data/nodekey
touch ./data/blskey
echo "{your-blskey}" > ./data/blskey
Generate a wallet
platon --datadir ./data account new

Connect to the PlatON network
| Options | description |
|---|---|
| --identity | Custom node name |
| --datadir | Data directory for the databases and keystore |
| --rpcaddr | HTTP-RPC server listening interface (default: "localhost") |
| --rpcport | HTTP-RPC server listening port (default: 6789) |
| --rpcapi | API's offered over the HTTP-RPC interface |
| --rpc | Enable the HTTP-RPC server |
| --nodiscover | Disables the peer discovery mechanism (manual peer addition) |
| --nodekey | P2P node key file |
| --cbft.blskey | BLS key file |
Run the following command to launch a PlatON node connecting to the PlatON's mainnet:
$ ./platon --identity "platon" --datadir ./data --port {your-p2p-port} --rpcaddr 127.0.0.1 --rpcport {your-rpc-port} --rpcapi "db,platon,net,web3,admin,personal" --rpc --nodiscover --nodekey ./data/nodekey --cbft.blskey ./data/blskey
OK, it seems that the chain is running correctly, we can check it as follow:
platon attach http://127.0.0.1:6789
