RAMBLE: Reliable Asynchronous Messaging for Byzantine Linked Entities

How to build: ./gradlew clean assemble

How to run:

./gradlew clean assemble
tar -xvf distribution-0.0.1.tar.gz
cd ramble-distribution
./bin/ramble-cli.sh -f /tmp/ramble-messages.txt

This creates one instance of the RAMBLE service that uses port 5000 for a Gossip membership service, and port 6000 for a message sync service. It does not connect to any peers. All received messages will be dumped to the file /tmp/ramble-messages.txt

To launch a RAMBLE service that connects to pre-existing peers, run the following command:

./bin/ramble-cli.sh -f /tmp/ramble-messages-2.txt -p ramble://[ip-address-of-first-node]:5000 -u 5001 -b ramble://[ip-address-of-first-node]:6000 -mm 6001

The value of ip-address-of-first-node can be find from the ramble.log file of the first node.

This creates another instance of the RAMBLE service with peer ramble://[ip-address-of-first-node]:5000, and it uses port 5001 for Gossip and port 6001 for message-sync.

When the RAMBLE service starts up, the CLI will have a prompt that looks like:

Post Message:

Type in a message and press ENTER to post a message.

All service logs are printed to the file ramble.log.

The current CLI options fot the ./bin/ramble-cli.sh script are:
