As a crypto analyst, I break down the recent SHA-256 collision attack breakthrough presented at EUROCRYPT 2024. While the academic achievement is real (31-step collision achieved), your Bitcoin isn't doomed - yet. I'll explain why this doesn't immediately threaten blockchain security, how SHA-256 protects your assets, and what would actually happen if full decryption became possible. Spoiler: we're not handing over our private keys anytime soon.
