Layered Multicast Network
The transport layer for Bitcoin at planetary scale
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.
A network built for throughput
Traditional peer-to-peer networks re-send the same data again and again to reach everyone. 1bsv broadcasts it once and lets the network carry it — a fundamentally more efficient way to move Bitcoin at scale.
One send, everyone hears
A transaction is emitted a single time and fans out across the fabric to every interested party — no duplicated floods, no wasted bandwidth.
Nothing slips through
Every stream is ordered 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.
Always the nearest door
Senders connect to the closest point of presence automatically. Today through advanced routing — tomorrow through global anycast.
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.
For users
Whoever you are, getting your transaction onto the network is the easy part.
Ingress transaction distribution is free
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. Wallets, apps, and individuals welcome.
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 building blocks are public and auditable; the global network is operated for the businesses that depend on it.
