A new blockchain startup has claimed its software could help track down criminals faster and cheaper than ever.

Sabr.io, one of 42 companies unveiled at 500 Startups' demo day in San Francisco this Tuesday, aims to shave valuable time off investigations into outfits such as illicit marketplace Silk Road.

The platform, which integrates data from public and proprietary sources, claims to provide law enforcement with intel on digital currencies that's "otherwise inaccessible".
