n3h delivers the networking component for holochain-rust. Core Holochain functionality is sheltered from the complexity of low level p2p networking.

n3h does NOT need to be installed manually by Holochain users or developers. Holochain itself will download and install a pre-built version of n3h ready for use on your system, alleviating any concerns of version compatibility and mismatches.

It did not previously work this way, n3h required separate manual installation prior to v0.0.12-alpha1 of holochain-rust.
