21 posts held, back to 13 March 2026 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 2 pages of Telegram’s post history, 20 posts per page.
Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 21 posts for this entry, the most recent from 7 August 2026. An engagement rate over an empty window would be a number about nothing.
Measured directly from 1 video with a duration reading, out of the posts we hold for this channel — not this channel’s whole posting history, only the sample this register has actually read. An exact reading to the second, taken from the post itself rather than from Telegram’s own rounded chrome, so it carries no ≈ mark.
Post-quantum signatures aren't one-size-fits-all, and now developers can find the SHRINCS setup that fits theirs. Blockstream Research's explorer lets you tune signature size, signing cost, and verification cost to match your wallet, node, or miner. Their sweep of 25,935 candidates found a fallback signature about 2 KB smaller than NIST's SLH-DSA, and 28% cheaper to verify. https://blog.blockstream.com/searching-f…

Jade is unaffected by the recently disclosed RNG vulnerability affecting other hardware wallets. Every Blockstream Jade recovery phrase comes from multiple independent entropy sources. On an affected device? Here's how to migrate calmly, step by step: https://blog.blockstream.com/jade-unaffected-coldcard-vulnerability/
The Blockstream Jade lineup (Jade Classic, Jade Core, and Jade Plus) is unaffected by the recently reported RNG issue with another company. We are preparing a blog post outlining best practices for anyone moving bitcoin to a new wallet, including how to generate fresh keys, verify addresses, conduct a test transaction and securely retire an old recovery phrase. Frontier LLMs are uncovering previously overlooked vul…
Simplicity has been live on Liquid mainnet for nearly a year. Now the full developer toolchain is here. Build high-assurance Bitcoin contracts in a zero-friction environment with autocomplete, instant testing, post-quantum signatures, and a finalized lending template. Here's what builders can ship today and what's coming next. https://blog.blockstream.com/building-on-simplicity-what-ships-today-what-is-coming-next…
New 0-conf infrastructure for Liquid and other Elements-based deployments is here. Swap services, exchanges and applications that accept Liquid payments now have access to near-instant transfer times. Details in the technical explainer below. https://blog.blockstream.com/0-conf-for-elements-and-liquid-a-technical-explainer/
Simplicity's site just got a full redesign. Simplicity lets you prove exactly how a contract behaves before it goes live. No surprise fees, no transactions failing mid-execution. The security guarantees are part of the language, not bolted on after. Live on Liquid mainnet, running real financial contracts, and built for the developers and institutions building high-assurance Bitcoin applications. https://blog.bloc…
When you run a Bitcoin node, you can prove the 21 million cap yourself. Every block. No trust required. The Zcash Orchard bug, undetected for four years, is a reminder of what you give up when supply verifiability is traded for privacy. The Liquid Network shows there is another way. Strong privacy with publicly verifiable supply. https://blog.blockstream.com/what-the-zcash-orchard-bug-reveals-about-verifiable-supp…
Core Lightning 26.06 "Quantum-Resistant Lightning Channel" has shipped. Graceful shutdowns, precise send amounts, smarter payment retries, and enhanced payment privacy. Your Lightning node runs cleaner and your payments stay harder to observe. ⚡ The big architectural shift in this release is bwatch, a new block-watching plugin that fundamentally changes how CLN interacts with the Bitcoin blockchain. No more 30-sec…
The results are in from the Blockstream Turin Simplicity Hackathon! 20 developers spent a weekend building real smart contracts on Simplicity covenant DEXs, inheritance tools, post-quantum wallets, and more. First place goes to: PQ Liquid Wallet, taking home $3,000 in bitcoin: PQ Liquid Wallet is the first wallet to test Blockstream's research on protecting Bitcoin from future quantum computers. Second and third pl…
There is no concrete post-quantum signature scheme for Bitcoin today. But over the last year Blockstream Research has been working on exactly this. Director Jonas Nick lays out the proposal: OP_CHECKSHRINCS, a hash-based signature opcode for post-quantum Bitcoin. SHRINCS reaches up to 3 TPS on the compact path. 580-byte signatures from a dedicated signing device. A stateless fallback always available. Already demo…
As the Liquid Network’s technical provider, Blockstream is sharing an updated roadmap for the core development workstreams it leads. 0-conf payments, quantum readiness, BitVM bridge exploration, institutional custody, Simplicity-based DeFi infrastructure, and much more are in development. Details. 👇 https://blog.blockstream.com/liquid-network-roadmap-0-conf-quantum-readiness-and-bitvm/
Showing the 12 most recent of 21 posts we hold for @blockstream. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
Named by 4 registered channels — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.
Named by
Channels on the register whose posts name this channel's handle.
A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
A live page changes as we take new readings, so a citation should name the measurement it is based on, not just the URL. The line below cites the subscriber count as measured 10 September 2026 — this entry's latest reading, not the date you are reading this.
