Running Store Protocol

TODO (2023-05-24): Deprecate or fix

How to

Build:

# make wakunode2 is run as part of scripts2 target
make scripts2

Run two nodes and connect them:

# Starts listening on 60000 with RPC server on 8545.
# Note the "listening on address" in logs.
./build/wakunode2 --ports-shift:0

# Run another node with staticnode argument
./build/wakunode2 --ports-shift:1 --staticnode:/ip4/0.0.0.0/tcp/60000/p2p/16Uiu2HAmF4tuht6fmna6uDqoSMgFqhUrdaVR6VQRyGr6sCpfS2jp --storenode:/ip4/0.0.0.0/tcp/60000/p2p/16Uiu2HAmF4tuht6fmna6uDqoSMgFqhUrdaVR6VQRyGr6sCpfS2jp

When flag persist-messages is passed messages are going to be persisted in-memory. If additionally flag dbpath is passed with a path, messages are persisted and stored in a database called store under the specified path. If flag persist-messages is not passed, messages are not persisted and stored at all.

You should see your nodes connecting.

Do basic RPC calls:

./build/rpc_subscribe 8545
./build/rpc_subscribe 8546
./build/rpc_publish 8545 # enter your message in STDIN
./build/rpc_query 8546 # enter your content topic; default is "1"

You should see other node receive something.
