10,000,000 OAS is required to validate the Hub-Layer node.
Firewall Settings
- TCP/UDP port 30303 allowed (for P2P between nodes)
- TCP port 8545 allowed (for RPC)
Validator Build Steps
- 1.Download the Oasys geth binary from github and place it in any directory (e.g. /usr/local/bin). (Or build it according to README.md)
- 2.Create an OS user to be used by geth.
1
$ sudo useradd -s /sbin/nologin geth
2
$ sudo mkdir /home/geth
3
$ sudo chown geth:geth /home/geth
4
$ sudo chmod 700 /home/geth

1
$ wget https://github.com/oasysgames/oasys-validator/releases/download/v1.0.0-alpha2/genesis.zip

3
$ unzip genesis.zip
4
Archive: genesis.zip
5
creating: genesis/
6
inflating: genesis/mainnet.json
7
inflating: genesis/testnet.json

9
$ mv genesis/{target network}.json /home/geth/genesis.json
Copied!
4. Create a genesis block.
1
$ sudo -u geth geth init /home/geth/genesis.json
Copied!
The following will be output.
1

5. Save bootstrap node configuration to
/home/geth/.ethereum/geth/static-nodes.json1
# For mainnet

6. Creates a secret key to be used by geth.
1
$ sudo -u geth geth account new
Copied!
The following will be output.
1
INFO [03-14|12:10:46.047] Maximum peer count ETH=50 LES=0 total=50

Public address of the key: 0xabcdabcdabcdabcdabcdabcdabcdabcdabcdabcd
10
Path of the secret key file: /home/geth/.ethereum/keystore/UTC--2022-03-14T12-11-06.835917424Z--abcdabcdabcdabcdabcdabcdabcdabcdabcdabcd

- You can share your public address with anyone. Others need it to interact with you.
13
- You must NEVER share the secret key with anyone! The key controls access to your funds!
14
- You must BACKUP your key file! Without the key, it's impossible to access account funds!
15
- You must REMEMBER your password! Without the password, it's impossible to decrypt the key!
Copied!
Important: Keep the secret key and password in a safe place.
7. Save the secret key password to a text file.
1
$ vi /home/geth/.ethereum/password.txt
Copied!
8. Start geth. For
YOUR_ACCOUNT_ADDRES, use the secret key address you just created.1
# For mainnet
2
$ export NETWORK_ID=248
3
4
# For testnet
5
$ export NETWORK_ID=9372

$ sudo -u geth geth \
8
--networkid $NETWORK_ID \
9
--syncmode full --gcmode archive \
10
--mine --miner.gaslimit 30000000 \
11
--allow-insecure-unlock --unlock {YOUR_ACCOUNT_ADDRESS} \
12
--password /home/geth/.ethereum/password.txt \
13

9. Immediately after startup, the block synchronization process takes place. The progress of synchronization can be checked with the following command.
1
$ sudo -u geth geth attach ipc:/home/geth/.ethereum/geth.ipc --exec eth.syncing
2
{
3
currentBlock: 34559,
4
highestBlock: 203190,
5
knownStates: 0,
6
pulledStates: 0,
7
startingBlock: 0
8
}
Copied!
Synchronization is complete when the output changes to
false.1
$ sudo -u geth geth attach ipc:/home/geth/.ethereum/geth.ipc --exec eth.syncing
2
false
Copied!
