Mining crypto is hard, investing in crypto is risky, but Pi makes crypto mining easy. Breakthrough tech allows you to mine on your phone without draining your battery.
Pi has rapidly grown to more than 500K installs, with active members spanning 180 countries. Conceived by Stanford grads, Dr. Nicolas Kokkalis, Dr. Chengdiao Fan, Vincent McPhillip, and Aurelien Schiltz the breakneck speed of Pi's adoption across a diverse, global user-base reveals the expanding interest in cryptocurrency and public desire to participate in a more inclusive digital economy.
Despite bitcoin's promise to democratize finance, it remains largely inaccessible because bitcoin mining—the most direct way to earn—is expensive, requires extensive technical knowledge, and consumes so much energy that mining operations are now a major contributor to global CO2 emissions.
By contrast, Pi's breakthrough technology harnesses the power of members' social networks to allow everyday people to contribute to the security of the currency. When Pi members vouch for each other as trustworthy, together they form a network of interlocking "security circles" that determines who can validate transactions on Pi's ledger. This allows members to earn Pi from their mobile phones with low financial cost, limited battery drain, and a light footprint on the planet.
