This PR contains some preliminary changes to allow for using ENR to transmit the swarm overlay address between peers.
Currently, ENR is not being sent over the p2p handshake. The necessary changes for this to happen is pending an EIP submission (and approval, and implementation). This is described in this PR by @fjl which incidentally also contains a hack by him that provides a functional demonstration on how ENR record will be available through
PeerInfoand on thep2p.Peerobject:#19220
In the meantime, the aim is to include the maximum amount of changes here that can be made towards the goal without relying on the implementation of the EIP. Some of the changes are cherry-picked from an experimental branch https://github.com/ethersphere/go-ethereum/tree/enr-bzz-poc building on the in the above mentioned PR.
In the experimental branch all handshake related code has been removed, and includes a temporary POC test
swarm/network/simulation/protocol_new_test.go:TestENRthat demonstrates a successfulWaitTillHealthy()only using ENR.My proposed steps towards the basic but sound transition to handshake-free Swarm are:
BEFORE EIP
AFTER EIP
