+# Following the problem described here:

+# It may be desireable to use http RPC provider.
+# This turns out to be equally important in tests where
+# subscriptions get wiped out after 5mins even when
+# a new block is mined.
+# For this reason, we are using http provider here as the default.

+# The nodes are still using the default provider (which is ws://localhost:8545).
+# If you want to use http provider url in the nodes, you can
