The next generation of the Qitmeer network implementation with the plug-able VMs under the MeerDAG consensus.
make sure you have go-lang version 1.21.x or above (1.22.x is recommended) installed on the system to build.
- Build from source
~ git clone https://github.com/Qitmeer/qng.git
~ cd qng
~ makeor
- Install the latest qng available here: https://github.com/Qitmeer/qng/releases
or
- Build with Docker:
~ docker build -t qng .Note : Swap 4G+ is required for running the mainent node otherwise you might need the 8G physical memory.
- setup the swap file
sudo apt update
sudo apt install --reinstall util-linux
sudo fallocate -l 4G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
- check the running swap file
sudo swapon -s
- edit
/etc/fstabfile (optional)
sudo vi /etc/fstab
add a line to the end of /etc/fstab file
/swapfile swap swap defaults 0 0
- We take the construction of test network nodes as an example:
~ cd ./build/bin
~ ./qng --testnet
~ docker run --rm -it --name qng qng:latest ./build/bin/qng --mixnet --acceptnonstd --modules=qitmeer --modules=p2p
- If you are a miner, you also need to configure your reward address:
~ ./qng --testnet --miningaddr=Tk6uXJ3kjh3yA4q94KQF9DTL14rDbd4vb2kztbkfhMBziR35HYkkx
- Please note that the mining address here is a PK address:
~ ./qx ec-to-public [Your_Private_Key] | ./qx ec-to-pkaddr -v=testnet
- If you use the old address(
PKH Address), you will only be unable to package the cross chain transaction.
Note: to use "qx" tool, you need to enter the directory ./cmd/qx to build the qx command, see this guide for details
- PKH Address:
~ ./qx ec-to-public [Your_Private_Key] | ./qx ec-to-addr -v=testnet
- PK Address:
~ ./qx ec-to-public [Your_Private_Key] | ./qx ec-to-pkaddr -v=testnet
- MeerDAG Address:
~ ./qx ec-to-public [Your_Private_Key] | ./qx ec-to-ethaddr
or
~ ./qx pkaddr-to-public [Your_pkaddress] | ./qx ec-to-ethaddr
or
~ ./qx pkaddr-to-ethaddr [Your_pkaddress]
- All addresses corresponding to the same private key:
~ ./cli.sh getaddresses [Your_Private_Key]
(Due to safety reasons, you need to actively open the private module by ./qng --modules=test)
- If you want to use our MeerEVM function, the required interface information can be queried in this RPC:
~ cd ./script
~ ./cli.sh vmsinfo
- If you don't need the default configuration, we provide an environment configuration parameter to meet your custom configuration for MeerEVM:
~ ./qng --testnet --evmenv="--http"
or
~ ./qng --testnet --evmenv="--http --http.port=18545 --ws --ws.port=18546"
~
- You first need to transfer your money in qitmeer to MeerEVM:
createExportRawTx <txid> <vout> <PKAdress> <amount>
~ ./cli.sh createExportRawTx ce28ec92cc99b13d9f7a658d2f1e08aa9e4f27ebcfaf5344750bb77484a79657 0 Tk6uXJ3kjh3yA4q94KQF9DTL14rDbd4vb2kztbkfhMBziR35HYkkx 11000000000
~ ./cli.sh txSign [Your_Private_Key] [rawTx]
~ ./cli.sh sendRawTx [signRawTx]
- Or you can use the multiple inputs or outputs version:
createExportRawTxV2 <inputs> <outputs> <lockTime>
~ ./cli.sh createExportRawTxV2 '[{"txid":"0e6aa3a41c6712ed5d68960f2315041579767a9d0a7be9988276cc802e2ae269","vout":0},{"txid":"2d1b3e5e89fbcec54368b7d98079bf533e38f1ce48bfd752582ea87bbac5cbca","vout":0}],[{"address":"Tk6tMafZQW1r2WzwW9V8ynq2HkLhc43nPaMivHTsJGvBUHRNLycPh","amount":11000000000},{"address":"TnNbgxLpoPJCLTcsJbHCzpzcHUouTtfbP8c","amount":999900000}]'
~ ./cli.sh txSign [Your_Private_Key] [rawTx]
~ ./cli.sh sendRawTx [signRawTx]
- Finally, wait for the miner to pack your transaction into the block. Then you have the money to start operating your MeerEVM ecosystem.
~ ./cli.sh createImportRawTx Tk6uXJ3kjh3yA4q94KQF9DTL14rDbd4vb2kztbkfhMBziR35HYkkx [amount]
~ ./cli.sh txSign [Your_Private_Key] [rawTx]
~ ./cli.sh sendRawTx [signRawTx]
- Finally, wait for the miner to pack your transaction into the block.
~ ./qng --testnet --evmenv="--http --http.port=18545 --http.api=net,web3,eth,qng"
~ ./qng attach http://127.0.0.1:18545
