[dirkmc]

Making changes to go-fil-markets means we also need to make the same change in boost and lotus, then run a comprehensive test suite on both of those projects, so it's not a simple task.
Is there an urgent need to make this change?

This PR doesn't bump any versions, so it shouldn't have any side effects on other repos. Or am I missing something?

[marten-seemann]

@dirkmc @hannahhoward Is there anything else needed to get this PR merged?

[dirkmc]

@marten-seemann is the code at

"github.com/libp2p/go-libp2p-core/peer"

exactly the same as the code at

"github.com/libp2p/go-libp2p/core/peer"

?

Same question for protocol, network, etc

[marten-seemann]

Yes, we moved go-libp2p-core into go-libp2p a while ago.
