Miao'A International Timechain (M.I.T) is dedicated to building a precision time-value-based transmission network. We highly acknowledge the time-value of money for each individual, and that the extent of which an individuals time is valued depends on how much he/she is needed by others, i.e. the more helpful an individual is, the higher the individual is needed. For the purpose of better presenting individuals time-value, and effectively matching the time exporters and time demanders, M.I.T will introduce TNB (a.k.a. Time New Bank) digital currency, based on a blockchain technology underlying platform, aiming to establish a time-value transmission network which comprises prominences of decentralization, internationalization, payment flexibility, pricing transparency, and strong protection of rights and proof-of-stake.
