CoinDesk spoke to the creators of an unusual project that aims to establish a complete sports ecosystem on the blockchain.
 
Developed by a team at Taiwan-based Fubon Life Insurance, Bravelog had its first live test last month at a triathlon. Wearables recorded race details as well as biometric data, and stored the information on a private version of ethereum built on Microsoft's Azure platform.
