Nubit Announcement | Bitcoin Thunderbolt

Introducing the next chapter of Bitcoin Thunderbolt, our fast, secure, asynchronous off-chain payment protocol for Bitcoin.

Today, we are open-sourcing Bitcoin Thunderbolt, and the research behind it has been accepted at ACM CCS 2026, a top-tier academic conference in security and cryptography.

More than a decade after Lightning, Bitcoin Thunderbolt brings asynchronous payments to Bitcoin, without routing or liquidity rebalancing, even when the recipient is offline.

A Bitcoin UTXO can pass from one owner to the next, repeatedly and entirely off-chain.

Momentum is building, and we’re just getting started.

Over the past few months:
- Ran Bitcoin Thunderbolt, the fastest Bitcoin-native upgrade, for 4,250+ hours with zero downtime (and counting).
- Our Thunderbolt paper was accepted by SBC'25, one of the world’s top blockchain conferences co-hosted by Stanford, IC3, and UC Berkeley.
- Launched the first circulation channel for a USD-backed stablecoin directly on Bitcoin.

Hit some major milestones:
- 500K+ Boosting Code entries
- 51K+ verified mainnet users
- $700M+ USD1 transaction volume
- 0.1s speed and 1 sat fees per transaction

These aren’t promises, they’re live onchain, peer-reviewed, and community-driven. That’s us, and that’s Nubit.

Boosting Bitcoin 3,750+ hours nonstop.

Avg speed: 0.1 sec/tx
Avg cost: 1 sats
Network errors: 0
