Launched on 01/09/2019 by a United States-based team, MASS is a basic infrastructure layer that provides consensus services across multiple public chains. The MASS consensus engine utilizes the Proof-of-Capacity consensus protocol to establish a sustainable and robust Layer 0. This protocol ensures a permissionless, fair, energy-efficient, secure, and universal consensus layer, thereby guaranteeing the security of the public chain. Participants only require access to storage space, such as hard drive space on a basic laptop. MASS is a hard drive mining project with no fundraising, premine, or founder rewards.
