🎤Fairgate will be at LABITCONF this Friday and Saturday! If you’re attending, come say hello and meet the team. We’d love to connect with the community, exchange ideas, and talk about what we’re working on. See you there! 🚀

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…

🔗Verifier inputs can now include Cosign inputs interleaved at arbitrary positions, enabling more flexibility and opening the door to counter-proofs within the protocol flow.

🛡️Database recovery capabilities have also been introduced, allowing the system to recover from corrupted database states and restore operation in a controlled way, making recovery scenarios much more manageable.

🔍The Bitcoin Indexer just got a major refactor focused on storage efficiency, scalability, and performance. Its indexing strategy now uses a bounded set of recent blockchain data, cutting storage needs while keeping the data required for protocol operation available.

🧠A new article covers Garbled Circuits for computing SHA-512 on Bitcoin. It enables funds to be locked to a SHA-512 preimage, with the hash evaluated off-chain as a Garbled Circuit and the result settled on-chain. Tested on Bitcoin Mainnet: bitvmx.org/knowledge/using-g…

Bitcoin Script by design, is not Turing-complete and even some useful opcodes were disabled due to security concerns. Here is where BitVMX comes in

Bitcoin Script has no native SHA-512. BitVMX enables funds to be locked based on a SHA-512 preimage, evaluating the hash function as a garbled circuit off-chain, settling the result on-chain with a fixed set of transactions. Tested on Bitcoin mainnet. bitvmx.org/knowledge/using-g…

Signing a Bitcoin transaction and handing it to a node is the easy part. Driving it all the way to a durable confirmation is the hard part.
