Why governments should be slow and careful with blockchains (medium.com)

Blockchain technology is very nascent. Building long-term tamper-resistant public infrastructure on top of a fast moving tech is *VERY* risky. What happens if the current cryptographic algorithms (hashing / encryption / digital signatures) get broken by scientific advancements such as quantum computing? Or the consensus algorithms turn out to have vulnerabilities that hostile actors can exploit? It will enable attacks that wouldn’t have been possible otherwise and will cause a major disruption.
