"What emerges is not merely an optimisation but a new layer of communication architecture. Where gossip was entropy, structured multicast is order. Where mempool flooding was waste, shard-level sequencing is precision. Where unicast was fragility, anycast ingress is resilience. Together, these mechanisms enable the Bitcoin system to scale to its design capacity—not thousands or millions, but billions of transactions per second—without sacrificing efficiency, fairness, or verifiability.
The lesson is simple: consensus begins not in cryptography but in communication. To scale digital cash globally, one must first scale the broadcast fabric itself. By embracing structured multicast—layered, sharded, and verifiable—we unlock the true potential of the system, transforming it from a fragile rumour network into an ordered, auditable infrastructure for global economic exchange."
