Safe stream aims to address the dilemma of using blockchain platform, where one has to trade accessibility of platform on one hand with the cost of running and energy usage, and the security on the other. We will introduce a new and revolutionary distributed ledger protocol that replaces Proof of Work (PoW) with Proof of Space (PoSc). This is our core innovation with significant costs reduction, sustainability impacts, and ever increasing democratisation of technologies that could deliver significant social impacts.

There is an ever more increasing recognition and use of blockchain technologies in various industries from finance to energy to supply chains. However, the dilemma of increasing costs of the conventional blockchain technologies, the increasing energy usage, and the reduced accessibility could hinder use of such technologies, or in some cases (for example, platforms based on Proof of Stake) limit it in the hands of a few with greater resources than the others.
