Hourglass is contributing to the digital economy with infrastructure to transmit and appraise the value of time. Hourglass invented the time-bound token (tbt), a primitive for digital assets whose value is directly connected with a specific time or duration. These tokens are cryptographically secured to enshrine a committed relationship, usually on blockchains, to provide an important building block in expressing long-term value.
