I run as README but get a blank web page:

So how to add nodes or commits? Could you demonstrate or add it to README?
Thanks.

Not quite sure why

Add a string field containing the hostname, the node would sent too
Or do we only store once per broadcast?
Store if sending to specific nodes failed?

docker-compose build
When all steps(18/18) are done, the error happens. Can someone help me fix this problem?

I have problem when following the instructions of Starting everything:
The 4 th step:
$ docker-compose scale node=4

error message as follow:

Is the error in any relation with "API_host variable is not set" and where is the API_host variable should be set?
Has anyone faced similar issues before and can offer some hints?
Sorry to bother you, thank you and appreciated for help!

when I want repeat on Ubuntu 18.04
I get this error：

docker.errors.APIError: 400 Client Error: Bad Request ("b'OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "/usr/lib/jvm/java-8-openjdk-amd64/bin/java": stat /usr/lib/jvm/java-8-openjdk-amd64/bin/java: no such file or directory: unknown'")

when I run step 4 :docker-compose scale node=4 get error ,I try step over this step

but step five alse have this question ?

@luckydonald
can you give me any suggestion

Is going upwards and after that downwards.

Not quite sure why that happens.
Most of the times after the sending of the InitMessages.

I want to learn the python version pbft and change your docker-composer.yml, from
node:
extends:
file: code/node_java/docker-compose.yml
service: node_java
volumes:
- /var/run/docker.sock:/var/run/docker.sock
environment:
NODE_DEBUGGER: "False"
NODE_DEBUG: "False"
# API_HOST: "http://192.168.0.42"
API_HOST: ${API_HOST}

to

node:
extends:
file: node.docker-compose.yml
service: node
volumes:
- /var/run/docker.sock:/var/run/docker.sock
environment:
NODE_DEBUGGER: "False"
NODE_DEBUG: "False"
# API_HOST: "http://192.168.0.42"
API_HOST: ${API_HOST}

and when I run docker-compose build, it has something wrong with installing the posrgres-browser like:

is there any way to solve this problem?

If I want to implement PBFT algorithm instead of proof of work, How can I implement this pbft algorithm?
lets take this tutorial http://adilmoujahid.com/posts/2018/03/intro-blockchain-bitcoin-python/ . How can i implement simple PBFT which can handle 5,6 nodes ?

Thank you

Add a string field containing the hostname, the node would sent too
Or do we only store once per broadcast?
Store if sending to specific nodes failed?

See the image for a mockup.
