Blockstream Enterprise — Institutional Momentum

Building on Q2’s robust launchpad, Blockstream Enterprise ramped up its institutional efforts this quarter, specializing in deepening relationships and constructing infrastructure for allocators, treasury groups, and monetary establishments. 

In early October, we pushed ahead with our efforts to broaden Bitcoin’s institutional attain in Asia with the Token 2049 Singapore occasion. Blockstream partnered with Safeheron and Komainu to host an occasion that introduced establishments and market leaders collectively to discover custody, infrastructure, and the way digital belongings combine with world commerce.

Later that month, Plan B Network week in Lugano shifted our momentum into overdrive. First was the Bitcoin Capital Summit: a non-public gathering targeted on the evolving panorama of Bitcoin-backed finance and capital markets. Hosted alongside STOKR and Fulgur Ventures, a choose group of founders, buyers, wealth managers, treasury groups, and monetary professionals gathered for a night of deep perception and private alternate. Through targeted talks and panel discussions, Blockstream CEO Adam Back explored key developments reminiscent of tokenization, bitcoin as collateral, and rising treasury options.

We capped off our flagship autumn presence on the Lugano Plan B Forum, the place our staff coated plenty of matters starting from asset issuance on Bitcoin, multisig mastery, Bitcoin company treasury evolution, Lightning, capital market tokenization, and extra.

Institutional demand for Bitcoin custody is rising like by no means earlier than. They acknowledge the vulnerabilities current in multi-coin options and more and more see Bitcoin because the premier, institutional-grade monetary asset. We are guaranteeing that demand is getting a heat welcome. 

Core Lightning — Scaling the Network

In the highlight of this quarter was the discharge of Core Lightning v25.09, aptly titled “Hot Wallet Guardian” by contributor @king-11. This launch got here full of new options and enhancements which all translate to a sooner, safer, and extra dependable Lightning expertise:

September additionally marked the thrilling Scaling Bitcoin Hackathon at BTC++ Istanbul. Eight groups of hackers competed for a grand prize of 5M sats, bridging UX and protocol improvement below the mentorship of our very personal Lightning protocol engineers, Lisa Neigut and Peter Neuroth, and our Head of Design Basak Haznedaroglu.

Behind the scenes, Blockstream’s Lightning Engineers have made will increase to fee success and reliability, continued to discover expanded LSP functionality and efforts to enhance the developer expertise utilizing Core Lightning and Greenlight. 

Greenlight — Minor Update, Major Impact

In July, our engineering staff released Greenlight v0.3.1 which noticed an improve for Greenlight nodes to now run the efficiency, protocol, and reliability enhancements made in Core Lightning v25.05. Our Lightning node runners can anticipate a sooner, extra secure, and extra price-environment friendly Greenlight service, whereas customers will take pleasure in much less friction and sooner, extra dependable funds for Greenlight-reliant companies.

Greenlight Principle Architect Christian Decker mentioned, “This launch has been within the making for fairly a while. Congratulations to all people concerned. It’s a minor launch in versioning however an enormous one in affect, routinely upgrading all nodes to CLN v25.05.”

With the most recent replace:

  • signer insurance policies have been refined, particularly round acceptable payment charges,
  • a zeroconf repair additionally ensures lengthy-confirming channels will not be closed,
  • Greenlight consists of the brand new signer for CLN v25.05, that means sooner commit/revoke messaging, tighter payment accuracy, and smoother channel administration.

Blockstream Explorer API — Gaining Traction

In the midst of all these thrilling updates, the Blockstream Explorer API has quietly develop into some of the relied-on items of Bitcoin infrastructure. From open-supply wallets to fintech dashboards and institutional analytics instruments, it underpins a rising variety of manufacturing functions in each the Bitcoin and Liquid ecosystems. Now, with a sequence of backend enhancements and new developer options, Explorer is coming into its subsequent part as a scalable, enterprise-grade API. 

  • Waterfalls is a brand new open-supply scanning instrument that helps mild purchasers scan for balances extra effectively, far surpassing the speeds of conventional electrum-fashion scanning, the place every handle must be individually calculated and queried. This means wallets can discover balances virtually immediately as an alternative of ready by way of gradual, handle-by-handle lookups.
  • Ark-ready relays have arrived, permitting purchasers to broadcast a number of transactions collectively as a bundle, which solves earlier mempool limitations that might reject low-payment dad or mum transactions and had been irreplaceable with high-fee variations, saving time and charges!
  • Along with these new options, our new Explorer API upgrade aligns Explorer’s mempool coverage with the broader Bitcoin ecosystem by lowering the minimal relay payment to 0.1 sat/vB. It could appear to be a minute technical element, nevertheless it has actual affect for builders and customers alike. Now, builders can depend on extra constant outcomes when working in low-payment or experimental transaction environments.

Blockstream Research — Security and Verification

Simplicity is likely one of the most enjoyable frontiers in Bitcoin at this time. In Q3 2025, practically a decade of analysis and developments culminated within the launch of Simplicity on Liquid mainnet on August 1st, bringing expressive and verifiable contracts poised to unlock a brand new wave of monetary tooling on Bitcoin. To help developer training, we launched Simplicity High-Level (SimplicityHL) toolchain and docs to organize builders for Liquid Bootcamps.

StarkWare has already integrated Simplicity by constructing a STARK verifier instantly within the language. “It reveals you you are able to do an infinite variety of very versatile issues with Simplicity and do it with high assurance,” mentioned Blockstream CEO Adam Back.

With the staggering enchancment of synthetic intelligence over the previous couple of years, we’re all left questioning whether or not main breakthroughs in computing will arrive a lot prior to anticipated. In explicit: quantum computing, and the way it probably threatens Bitcoin’s safety. What occurs if quantum computing can break Bitcoin’s Schnorr and ECDSA digital signature schemes?It’s attainable that the muse for an answer is already in place, and Blockstream Research’s Cryptography Engineer Tim Ruffing sees it inside Taproot. The Post-Quantum Security of Bitcoin’s Taproot as a Commitment Scheme, launched in July, supplies justification for a Taproot-based strategy by demonstrating the improve’s put up-quantum safety.

Meanwhile, our Cryptography staff, led by Jonas Nick, has been persevering with the arduous work on a trifecta of developments: DahLIAS, ChillDKG, and Shielded CSV.

  • Efficient information use retains Bitcoin accessible for on a regular basis node runners. However, extra advanced transaction schemes enhance information necessities as they contain extra signatures. Discrete Logarithm-Based Interactive Aggregate Signatures (DahLIAS) addresses this drawback. As Jonas Nick puts it, “A DahLIAS signature is at all times 64 bytes…no matter what number of messages and signers that now we have”. In addition, verification is twice as quick as batch verification of n particular person Schnoor signatures. Jonas joined Brink engineers in July to debate extra.
  • ChillDKG, alternatively, is a distributed key technology (DKG) protocol that enhances schemes like DahLIAS by offering a sturdy strategy to generate and refresh shared keys with out trusting a single get together.
  • Last however not least, Shielded CSV units a precedent for enhancing on-chain privateness—making it attainable to cover spending situations and enhance transaction confidentiality on Bitcoin’s base layer, all with out requiring a comfortable fork.

Together, these developments are supporting Blockstream Research’s broader effort to make Bitcoin contracts extra non-public, safe, and programmable.

Want to get began on constructing initiatives like these your self? Jonas Nick created Provable Cryptography for Bitcoin: An Introduction, a complete workbook that teaches formal safety definitions and proofs by way of palms-on workouts with options included. It’s free to download for builders and college students alike.
