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…

✨BitVMX keeps pushing forward, with the system becoming more robust, efficient, and capable with every step. We’re excited about where this is heading, and there’s a lot more to come. Stay tuned! 🔥

🛡️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 Broker refactor also continues to progress, with a simpler interface, improved information handling, removal of deprecated functionality, significantly broader test coverage, and updated documentation. Using and understanding the Broker is now easier than ever.

🔗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.

🔍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…

⚙️The Bitcoin coordinator refactor is now complete, with additional documentation and robustness improvements. We also published a detailed article explaining its architecture and operation: bitvmx.org/knowledge/a-bitco…

BitVMX | A Bitcoin Transaction Coordinator

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.

The storage comparison path was also refined to avoid unnecessary decryption work and handle encrypted stores more robustly, improving both efficiency and reliability.

The Broker now takes advantage of these limited scans across its storage operations, while duplicated scan logic was consolidated into shared helpers.

🗄️Storage access was optimized with bounded prefix scans, allowing targeted lookups to stop as soon as the required number of entries is reached instead of processing the full prefix range.

🧠The Garbled Circuits setup flow was reorganized to better structure the proof data exchanged between the different stages, resulting in a cleaner and more streamlined setup process.

🧪The client now supports Simchain, a Bitcoin simulation environment designed to stay close to Mainnet behavior while running locally, with multiple P2P-connected nodes and rotating miners.

Dependabot, cooldown policies, and additional tooling now provide greater control over dependency changes and help reduce exposure to supply-chain risks.

🔏Security and dependency management were strengthened across the projects, with dependencies brought up to date and new controls introduced around dependency updates and execution.

Signing a Bitcoin transaction is easy. Getting it to a durable confirmation is not. A new BitVMX article breaks down a Transaction Coordinator library: broadcast, tracking, automatic fee bumping via CPFP/RBF, and structured event reporting. bitvmx.org/knowledge/a-bitco…
