Human-curated signal, not automated noise
Every link is reviewed by a security practitioner with 20+ years of experience. BlockThreat is researched and manually curated, not automatically assembled from scraped feeds or AI-generated summaries.
The weekly blockchain security briefing
One week of blockchain security, distilled.
The incidents, vulnerabilities, postmortems, and research worth your attention, in one briefing a week. All of it carefully curated and analyzed by hand to extract why each one broke, the lessons worth keeping, and statistics from every incident since 2011. That is how emerging threats get named here before they become breaches.
