1BSV has introduced a layered multicast network for distributing BSV transactions and blocks at scale. The project describes itself as “the transport layer for Bitcoin at planetary scale,” moving transactions and blocks to participants through a multicast design rather than repeated node-by-node flooding.

The 1BSV site says the network is built for throughput, with transactions emitted once and carried across the network fabric to interested participants. It also describes ordered and accountable streams, missing-data repair, and horizontal scaling across independent lanes. The site says the system is engineered for 1B+ transactions per second, while also offering free ingress transaction distribution for wallets, apps, and individuals. (1bsv)

The related open-source GitHub repository, maintained by Lightweb Inc., describes BSV Layered Multicast as a high-throughput, horizontally scalable transaction distribution system using IPv6 multicast, deterministic sharding, and NACK-based reliability. The repository presents the project as a concrete implementation of sharded ingress, multicast fan-out, retransmission, and hierarchical distribution for BSV transactions and blocks. (GitHub)

BSV TIMES read:
This is a meaningful network-infrastructure item because it addresses one of the less visible but essential parts of scaling: transaction and block distribution. Large-scale BSV usage depends not only on block processing capacity, but also on efficient movement of data between miners, transaction processors, exchanges, service providers, wallets, and applications. 1BSV’s multicast approach fits BSV Blockchain’s infrastructure direction by focusing on throughput, reliability, and efficient data propagation.
