1. Setup
1.1 Recommended Hardware Requirements
At least 2 TB space of fast SSD drive
1.2 ETHW source code
The golang implementation of the ETHW protocol is at GitHub https://github.com/ethereumpow/go-ethereum
Download the code and build it
Copy git clone https://github.com/ethereumpow/go-ethereum.git
cd go-ethereum
make
2. Prepare
The ethw fork need to prepare the data before Ethereum total terminal difficulty(TTD) was reached. There are several ways to prepare chinadata:
2.1 Download the prepared data
The following commands were run at ubuntu 22.04 LTS
platform. The downloaded file is about1.1T
. You can download the file chaindata_15509444.tar.lz4
via BT network or HTTP.
BT is recommeded download method since the p2p network provides better downlaod speed.
2.1.1 Download data file
Install download tool packages
Copy sudo apt install transmission-cli -y
sudo apt install lz4 -y
sudo apt install aria2 -y
The file can be download by BT transmission:
Copy cd YOUR_DOWNLOAD_DIR
wget http://snapshot.ethwscan.com/15509444.torrent
# check your download
openssl sha256 15509444.torrent

or download from http
Copy aria2c -s16 -x16 -k100M http://snapshot.ethwscan.com/chaindata_15509444.tar.lz4
After download is finished, verify download file
Copy openssl sha256 chaindata_15509444.tar.lz4

2.1.2 Decompress and unpack the files
Copy lz4 -cd chaindata_15509444.tar.lz4 | tar xf -
2.1.3 Verify chaindata in a stand-alone network(optional)
Copy # create a new dataspace
geth --datadir YOUR_DATA_SPACE
# Ctrl+C to quit
rm -fr YOUR_DATA_SPACE/geth/chaindata
mv YOUR_DOWNLOAD_DIR/chaindata YOUR_DATA_SPACE/geth/
geth --datadir YOUR_DATA_SPACE --syncmode full --nodiscover console
# Check log is clean
# check block number
> eth.blockNumber
15509444
2.2 sync the chaindata from Ethereum network
Also, you can do a full sync from ethereum network to get the chinadata before ETHW fork(It could take one week or two weeks).
Stop the sync before total terminal difficulty(TTD) 58,750,000,000,000,000,000,000 is reached.
3. Run
To run a fullnode, execute this command after ETHW fork
Copy geth --datadir YOUR_DATA_SPACE --syncmode full
