Our service discovery simulator for Ethereum 2.0, included in this repository, is based on an existing P2P simulator, PeerSim P2P Simulator. We extended PeerSim to adapt to the current Ethereum DHT implementation and we added the implementation of our service discovery proposition, along with other ones for comparison purposes.
To run the project the following software requirements are necessary:
- Java version 11 or higher
- Maven
On Ubuntu run the following to install them:
$ sudo apt install openjdk-14 mavenRun the following command to build the project:
$ git clone https://github.com/harnen/p2p-service-discovery.git
$ cd service-discovery
$ mvn package$ ./run.sh <config_file>All the config files are in ./config/ check this folder for config file descriptions.
We provide a set of configuration files in order to simulate different setups, placed in the ./config/ folder
-
simple.cfg: It performs a single Kademlia lookup with no topic registration or service discovery.
-
discv5ticket.cfg: This configuration sets a scenario where a set of nodes are performing topic registration and discovery using discv5 tickets mechanism described here.
-
discv5proposal.cfg: This configuration sets a scenario where a set of nodes are performing topic registration and discovery using our service discovery proposition for discv5.
-
ethclient.cfg: This configuration set ups a scenario where nodes behave as Ethereum clients, having a list of active connections and performing lookups to fill up the DHT table when a slot is empty in the list of connections. No discv5 is simulated in this configuration yet.
-
ethclientdns.cfg: Same than previous one but loading nodes from Eth crawling results
