You mean you want to mine from multiple nodes but into a single sighash, right?
You can reuse the same sighash on multiple nodes to achieve what you want.

rpc 값 등을 동일하게 사용해서 각각의 컴퓨터에서 마이닝해도 되는건가요?
Can I use the same rpc value, etc. and mine on each computer?

Thank you for answering this.
Then can you share commandline how to put same sighash on multiple nodes?

you’d want to update the key values in the validator container… Something like:
```
docker exec -it sawtooth-validator-default bash
echo "new private key here" > /etc/sawtooth/keys/validator.priv
echo "new public key here" > /etc/sawtooth/keys/validator.pub
exit
docker-compose down
docker-compose up
```
You could also point the `/etc/sawtooth/keys/` path to a local directory. Something like:
1. Create a directory under `Server` called `keys`
2. Put your desired `validator.priv` and `validator.pub` keys there
3. Update the docker-compose file:
Change:
```
- type: volume
source: validator-key-volume
target: /etc/sawtooth/keys/
```
to:
```
volumes:
- ./keys:/etc/sawtooth/keys/
```
1. Restart docker: `docker-compose up`

Thanks. I thinks it should be added to mining guide line!
