A paper that I paused in 2025... and now I can finish much faster with the help of AI: nitter.cf/bitvmx/status/21107943…
New research from Fairgate's CTO, @SDLerner: FlatMerkle. The paper introduces a way to achieve compact, logarithmic-size inclusion proofs using a single linear hash stream, without requiring a traditional Merkle tree. Read the paper: eprint.iacr.org/2026/2468.pd…

When I designed a hardware wallet in 2013, I placed the electronics it in a transparent acrylic case: coindesk.com/markets/2013/06… Protecting from tampering in the supply chain was essential. I hope all hardware wallet manufacturers start offering transparent devices. bitcointalk.org/index.php?to…

What if scaling Bitcoin isn’t about making it do more, but making it better at securing what gets built on top?

In mid-2025, the Fairgate team ran the numbers on the Lightning Network as an agentic payment rail: transaction costs, locked collateral, routing complexity, payment success rates, mass-exit safety. The conclusion was hard to accept. Lightning, for all its contributions to Bitcoin, couldn't economically compete with centralized rails like Base or Tempo for machine-to-machine commerce at scale. So the choice became binary: let centralized companies own the agentic economy, or build Bitcoin a new Layer 2 from first principles. That's where Bit2 started.
