For apps
The overlay side of the network, for the applications that serve everyday users: wallets, exchanges, and services. Your users transact for free; you hand them certainty in return.

Publish once. Every overlay hears.
Applications run on overlays: token ledgers, payment rails, data feeds, whole ecosystems riding Bitcoin. 1BSV delivers to all of them the way it delivers everything: one send, carried to every subscriber simultaneously, with proof attached.
Every audience, one send
Publish an object and every overlay subscribed to its topics receives it in the same instant: your wallet users, your exchange integration, your analytics pipeline, all working from the same object at the same moment. One submission can even name several topics at once, so related overlays hear together. No fan-out servers, no webhook farms, no sync drift between your own services.
Proof, not promises
Each object arrives complete with its Merkle proof, ready to check against a live header feed. Every subscriber, and every end user behind them, verifies independently, the moment it lands. No trust chain between services, no "confirmed, probably."
Cost tracks interest, not the chain
Subscribe by topic and receive exactly your slice; your bandwidth follows what your users care about, never chain volume. And because the network carries the fan-out, a growing audience adds nothing to the publisher's side: one send reaches ten subscribers or ten thousand.
This is what multicast buys an application: simultaneous, verifiable delivery to every overlay you serve, and to everyone else subscribed to the same topics. The object plane is published as open standards you can verify (BRC-148 and BRC-149 on the Standards page).
Built for the businesses that serve users
Applications & Wallets
Serve your users overlay objects with proofs attached and a live header feed: SPV certainty for everyone you serve, without running mining infrastructure.
Exchanges
See the activity your markets depend on sooner, on a stream you can verify rather than trust.
Service Providers
Build on reliable, verifiable delivery without running the whole stack yourself.
Need the settlement-layer transaction stream itself, without operating mining infrastructure? That will be supported through a separate tier offering as demand requires: get in touch.
Your users ride free
Every transaction your users send enters the network for free. What you pay for is the certainty you hand back to them.
- Volume-only You are billed for the overlay objects and proofs delivered to you, and for nothing else. No subscriptions, no minimums, no commitments.
- Ingress is never billed Publishing into the network, and the network's own repair retransmissions, cost you nothing.
- Keys & failover A standard WireGuard tunnel with a primary and a standby path and automatic failover. You generate the keys; we only ever hold the public half.
