1. blockstream
Blockstream has published its Q1 2026 update, marking several technical milestones across the Liquid Network and Lightning infrastructure. Most notably, the company executed the first post-quantum signed transactions on Liquid, a significant proof-of-concept demonstrating that post-quantum cryptography can be deployed on a Bitcoin sidechain today without waiting for mainchain protocol changes. The quarter also brought the first hardware wallet-secured Lightning payments and the launch of real-time blockchain data infrastructure aimed at application developers. These releases collectively represent progress on three distinct fronts: quantum resistance, self-custodied Lightning, and developer tooling. Blockstream’s work on Liquid as a proving ground for post-quantum signatures is particularly relevant given the broader industry conversation about Bitcoin’s long-term cryptographic posture and the need for practical migration pathways.

The Bitcoin Policy Institute has released a strategic analysis tracing how bitcoin evolved from a network dominated by Chinese mining infrastructure into a flashpoint of U.S.-China competition for digital asset influence. The report covers the Trump administration’s Strategic Bitcoin Reserve, the $15 billion Operation Prince seizure of illicitly held bitcoin, and the emerging policy landscape across Indo-Pacific nations. The Institute frames the region as a key battleground as governments assess whether bitcoin represents a tool for financial sovereignty or a vector for sanctions evasion and capital flight. The analysis is notable for treating bitcoin not as a commodity or investment vehicle but as a strategic resource with geopolitical implications comparable to rare earth materials or telecommunications infrastructure. For policymakers and advocates, it provides a structured view of how digital asset policy is being shaped by great-power competition rather than domestic financial regulation alone.

The Electronic Frontier Foundation reports that Google has moved up its estimated deadline for quantum preparedness in cryptography to 2029, just 33 months away, earlier than the company’s previous projections and a significant compression of the timeline the industry has been planning around. EFF frames the shift as an inflection point comparable in urgency to Y2K, where the problem is well understood but the migration work is enormous and the window for orderly transition is narrowing. Google has proposed new post-quantum cryptographic standards to replace currently deployed protocols, but widespread adoption across internet infrastructure will require coordination across browser vendors, certificate authorities, server operators, and standards bodies. For the Bitcoin community, the parallel with BIP-360 and post-quantum address migration is direct: the 2029 horizon puts pressure on protocol developers to finalize and ship quantum-resistant signature schemes before the threat window opens.

Blockspace Media examines the paradox at the center of Iranian bitcoin policy: the country formally banned bitcoin mining years ago, yet now appears to be exploring mechanisms to collect bitcoin as a toll from oil tankers seeking to conduct transactions outside the reach of U.S. sanctions. The piece traces how Iran’s relationship with the network evolved from outright prohibition to state-adjacent exploitation, driven by the reality that dollar-denominated sanctions make any payment rail operating outside SWIFT attractive to sanctioned governments. The analysis highlights how bitcoin’s permissionless nature creates genuine policy complexity for both the countries trying to sanction Iran and the governments trying to operationalize bitcoin as a sanctions-evasion tool. The story is a useful data point for thinking about how nation-state actors are engaging with bitcoin not as investors but as users seeking financial sovereignty under duress.
