Tachain creates the synergy between transportation, entertainment and advertising. We are going to create ecosystem which will allow people to earn cryptocurrencies by watching targeted ads while using transportation service providers. Advertisers will need TCHN tokens in order to join our comprehensive platform and show their content to Tachain users. Tachain ecosystem will consist of three elements - Transportal (application for transportation service providers and users), AdNet (platform for advertisers) and TMARQ (internal mechanism to exchange TCHN tokens into any other crypto in a matter of seconds). Transportal MVP has been already released and is available at AppStore.
