Gold has doubled in two years! Markets are searching for safety. Bitcoin offers an alternate route. In "The Gold Reset" @Peruvian Bull breaks down what's unfolding and why self-custody with Blockstream Jade is how you prepare.

🚨 New Bitcoin price competition is live on the x.com/BlockstreamJade account! 🚨 Enter there for a chance to win $2100 in BTC!

Our CEO @Adam Back sat down with Simply Bitcoin Founder @NICO⚡️ to discuss why retail is asleep while institutions stack harder than ever, why the supply crunch may hit faster than expected, and why layer-2 is critical to Bitcoin's next phase.

Five years ago, nobody expected governments and institutions to buy or mine Bitcoin. Now they’re building portfolios around it. Price is down? Opportunity knocks. Download the Blockstream app and stack sats while institutions are still filling out paperwork. We are so early. But not forever.

Our CEO @Adam Back has been building cypherpunk systems for decades—starting even before Bitcoin existed! Now he'll share insights on "Designing Systems from the Cypherpunk Perspective" on the Treasury Stage @Bitcoin Magazine Conference in Amsterdam with Shinobi. 📅 Nov 14, 3:30pm

Most Lightning wallets blur the line on custody. In the latest blog from the VLS Project, Greenlight stands out as the model that lets builders offer Lightning access through apps or wallets without giving up control. ⚡️ Node ops in the cloud, signing on-device. Built on Core Lightning and powered by the VLS Project, Greenlight shows how to implement Lightning infrastructure without custody risk: ✅ Professionally managed nodes ✅ Validated signing on user devices ✅ APIs for wallets and services to go self-custodial Read the full custody-model report:

The latest $128M Balancer exploit is a reminder of something fundamental: most smart contracts today rely on audit-based hope*.* Developers write complex code, auditors review it, and everyone hopes there are no hidden logic flaws. But hope isn’t assurance. --- Simplicity takes a different approach. Developed by Blockstream Research in 2017, it’s a formally verifiable language. Meaning contracts can be mathematically proven to do exactly what they’re intended to do, and nothing more. No audits are required to verify the contract is doing what it is supposed to do. --- To understand why this matters, consider what causes most DeFi hacks: - Ambiguous conditions - Unchecked assumptions - Logical edge cases that humans miss Audits catch some of these, but not all. Simplicity eliminates ambiguity at the language level. --- How does it work? Simplicity is designed to be mathematically rigorous and predictable. As a low-level functional language, it allows mechanical reasoning about behavior, with proofs verifiable before any on-chain deployment. --- General-purpose languages are great for flexibility, but that flexibility comes at a cost: ambiguity. A single unchecked assumption in a general-purpose contract can have systemic financial consequences. --- Simplicity was engineered for high-assurance financial programming, where correctness, termination, and behavior can be *proven* before deployment. Its semantics are clear, and its outcomes deterministic. --- The goal isn’t “more expressive” smart contracts. It’s contracts that can’t fail silently, because they’ve been verified to work exactly as intended. That’s the difference between general-purpose code and high-assurance engineering. --- Simplicity was launched on the @Liquid Network July 31, 2025 and has been live since. Further integrations are underway for: - AMP - Enabling verifiable issuance and asset control - Enterprise Custody Solutions (ECS) - providing proof-backed execution paths for institutional custody workflows --- Simplicity prioritizes reliability over expressiveness. Rather than expanding complexity, it establishes a verifiable foundation. --- In short: Simplicity moves smart contracting from “we think this is secure” to “we can prove it is.” The Future of Finance Runs on Bitcoin 👉 Learn more:

Today marks 17 years since Satoshi Nakamoto released the Bitcoin Whitepaper — introducing a peer-to-peer electronic cash system with no trusted parties, built on proof-of-work from @Adam Back' Hashcash. This idea changed money forever. See a recreation of the moment Satoshi reached out to @Adam Back about Hashcash to cite in the Bitcoin whitepaper, an email exchange that helped lay the foundation for proof-of-work and the entire Bitcoin network. “The root problem with conventional currency is all the trust that’s required to make it work.” — Satoshi Nakamoto, Bitcoin Whitepaper Secure your stack without a trusted third party. https://store.blockstream.com/products/jade-plus The blueprint for freedom is still hosted on Blockstream servers.
