Milestone 3.4: Gossip (CODE SNAPSHOT / NON-PRODUCTION READY)

The attached tarball is a the final code artifact resulting from our demonstration of our completion of Milestone 3.4: Gossip. This code comes from a private staging repo and contains all of the code necessary to demonstrate our implementation of gossip. We provide this artifact as-is, and does not represent the final state of the code for Firedancer.

The artifact can be found in the files below and in the source code at the tag milestone-3.4 or commit 411673dcd1593ff7e4b44c88df0fc391d9e03eeb. Please use compiler clang version 16.0.6 when building.

NOTE: THIS CODE IS NON-PRODUCTION READY AND SHOULD NOT BE USED FOR PRODUCTION SYSTEMS! It is for demonstration purposes only and is not polished and audited to the standard necessary for use in the primary parts of the Firedancer validator client.
