BSV Layered Multicast Network
The transport layer for Bitcoin at planetary scale
Cash moves fast. Users always free. — on 1BSV
1BSV moves transactions and blocks to every participant the instant they happen — one signal, heard everywhere, without the waste of flooding the network node by node.
Today's bottleneck is the rumor mill
Bitcoin nodes still share data by gossip — whispering each message from peer to peer and hoping it spreads. As the network grows, that breaks down in three ways.
The same message, over and over
Every node re-sends to every other node. The traffic multiplies as the network grows.
No one knows who heard what
There's no record of who received a message, when, or in what order.
Things go missing quietly
If someone misses a message, no alarm goes off — and in a financial system, that is the failure you cannot tolerate.
The engine, and the road it drives on
Bitcoin's ambition is unbounded on-chain scale. The engines built to chase it keep getting faster — but the way nodes talk to each other was still gossip. You can't put a global-scale engine behind a rumor mill.
1BSV replaces the propagation layer — the road network that carries every transaction and block between participants. We don't compete with the engine. We remove the wall in front of it.
Like a postal service — with tracking numbers
Instead of shouting to everyone, 1BSV sorts every message by a rule anyone can verify, sends it once, numbers it, and repairs anything that goes missing.
One send, everyone hears
Enter at the nearest door and a transaction is emitted a single time, fanning out across the fabric to every interested party — no duplicated floods, no wasted bandwidth.
Nothing slips through
Every stream is numbered and accountable. The moment anything is missing it is detected and repaired — silent loss is impossible.
Engineered for 1B+ tx/s
Capacity grows by spreading load across independent lanes. Add throughput without re-architecting — the design scales horizontally.
Built to cover the planet
The vision isn't a few regions — it's ingress points everywhere, eventually thousands of them. There's no central bottleneck: the network grows by adding network and compute, both commodity, both horizontal.
Who it's for
Infrastructure for the businesses that process Bitcoin at volume.
Miners & Transaction Processors
Receive transactions and blocks the instant they propagate with predictable, deterministic delivery — less orphaning, faster assembly, sustained throughput.
Exchanges
See confirmations and chain activity sooner, with an auditable stream you can trust.
Service Providers
Build on a reliable feed of transactions and blocks without running the whole stack yourself.
Users always free. Receivers pay for certainty.
For senders — wallets, apps, individuals
Submitting a transaction to 1BSV — and having it fan out across the global network to everyone who needs it — costs nothing. Send through the nearest entry point and the network carries it the rest of the way. No account, no config. The only fee you ever see is the miner's — untouched.
For receivers — apps & miners
Guaranteed receipt: nothing arrives late or goes missing unnoticed. Publish once and reach every subscriber, so your distribution cost stays flat as your audience grows. Download a config, connect, done. Receivers pay for guaranteed delivery of the flow they earn from.
Open at the core
The deployed network. The open componentry. Built by Lightweb Inc.
1BSV is the production deployment of a layered multicast distribution system engineered and open-sourced by Lightweb Inc. The full protocol is published as open standards anyone can implement and verify — no black box, no vendor lock-in.
