Environment & Configuration
1.download
By downloading the source code git
under construction
2.install Golang
Reference: (https://golang.org/doc/install)
3.configure validator
3.1 Generate extraData
Open documents/extra/ExtraData.go, change the data inside according to the comments, and then execute the main function
If you are inconvenient to execute Go code locally, you can implement this logic in other languages, and then execute it, or even manually splice it
After execution, you will see a string of strings in the console
0x000000000000000000000000000000000000000000000000000000000000000058b1E31682C95417be998b27db00731b54b7E5EC64d374ed85C21473ED84A95fD7319D8D55c33320CD2a39BAe63f8A4A8c0230e5c8DE12906c23Bad20000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
Additional description:
1. There are several validator accounts configured here, which means only a few nodes can produce blocks. The node producing blocks needs to configure the private key of the validator account, start mining, and see the documentation for the mining method. &Run the mining link in
2. Each node can only be assigned one validator, and the number of nodes producing blocks must be greater than [number of validator accounts / 2]
3.2 Paste the string printed above into the configuration
Open config/Config.go and set the string printed above to the values of these two constants. Almost all the following configurations are changed in this file
// Mainnet configuration
;const (
MainNetExtraData =
"0x000000000000000000000000000000000000000000000000000000000000000058b1E31682C95417be998b27db00731b54b7E5EC64d374ed85C21473ED84A95fD7319D8D55c33320CD2a39BAe63f8A4A8c0230e5c8DE12906c23Bad20000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000"
// MainNetPeriod Block interval
MainNetPeriod = 5
// MainNetEpoch
MainNetEpoch = 200
)
// Testnet configuration
const (
TestNetExtraData =
"0x000000000000000000000000000000000000000000000000000000000000000058b1E31682C95417be998b27db00731b54b7E5EC64d374ed85C21473ED84A95fD7319D8D55c33320CD2a39BAe63f8A4A8c0230e5c8DE12906c23Bad20000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000"
// MainNetPeriod Block interval
TestNetPeriod = 5
// MainNetEpoch
TestNetEpoch = 200
)
4.Allocation of initial assets
4.1 Open core/genesis.json and find this paragraph
Change the addresses and assets inside as required. This passage means to initialize xx assets to xx addresses
"alloc": {
"0x58b1E31682C95417be998b27db00731b54b7E5EC": {
"balance": "0x100000000000000000000"
}
}
If you want to initialize assets for multiple addresses, you can configure multiple addresses, such as
"alloc": {
"0x58b1E31682C95417be998b27db00731b54b7E5EC": {
"balance": "0x100000000000000000000"
},
"0x58b1E31682C95417be998b27db00731b54b7E5EC": {
"balance": "0x100000000000000000000"
}
}
Note: in the original file
000000000000000000000000000000000000C000，000000000000000000000000000000000000C001， 000000000000000000000000000000000000C002 These three options must not be changed
4.2 After configuration, execute in the directory where this file is located
./mkalloc genesis.json
4.3 will output the return value after execution
const allocData =
"\xf9h\x84\xf9Ic\x82\xc0\x00\x80\xb9I。。。"
4.4 Copy this return value to config/Config.go
Just modify the values of these two constants
// Mainnet configuration
const (
// MainNetAllocData after modifying genesis.json, execute ./mkalloc genesis.json to obtain
MainNetAllocData = ''
)
// Testnet configuration
const (
// TestNetAllocData After modifying genesis.json, execute ./mkalloc genesis.json to obtain
TestNetAllocData = ''
)
If you want to configure the main network and test network separately, you can repeat steps 1-2 to generate two allocData and assign values to these two variables respectively
5.Modify chainId and networkId as required
Open config/Config.go, pay attention to the comments below, the Id of the main network and the test network cannot be the same
// Mainnet configuration
const (
MainNetChainId = 520
MainNetNetworkId = 520
)
// Testnet configuration
const (
TestNetChainId = 530
TestNetNetworkId = 530
)
6.Administrator who configures the creation contract
Open config/Config.go and modify the following constants. The following value is the wallet address of the administrator you want to set
// Mainnet configuration
const (
MainNetValidatorV1Admin = '0x58b1E31682C95417be998b27db00731b54b7E5EC'
MainNetGovAdmin = '0x58b1E31682C95417be998b27db00731b54b7E5EC'
MainNetDevAdmin = '0x58b1E31682C95417be998b27db00731b54b7E5EC'
)
// Testnet configuration
const (
TestNetValidatorV1Admin = '0x58b1E31682C95417be998b27db00731b54b7E5EC'
TestNetGovAdmin = '0x58b1E31682C95417be998b27db00731b54b7E5EC'
TestNetDevAdmin = '0x58b1E31682C95417be998b27db00731b54b7E5EC'
)
7.Modify GenesisHash
This needs to be run to get the value to be configured, so you don't need to worry about it, wait until you finish compiling, and then come back after startup.
7.1 After startup, enter this command in the console
admin.nodeInfo
Then you will see the return value like this

}
}
Copy the value of the genesis attribute and paste it to config/Config.go
// Mainnet configuration
const (
MainNetGenesisHash = '0x97b9fd09f9ecbef2ca407c2c039b882ebf7d27'
)
// Testnet configuration
const (
TestNetGenesisHash = '0x97b9fd09f9ecbef2ca407c2c039b882ebf7d27'
)
Notes:
1. If the other configurations of your main network and test network are separate, then you have to start the main network and test network separately, obtain genesisHash separately, and configure them in the above two brackets
2. After completing this step, recompile and restart the node with the recompiled package [Before starting, you need to delete the data directory generated just before starting]
3. Be sure to finish reading, compiling and starting, and come back to see this later, otherwise it's easy to be confused
