Chia

Green, smart money, farmed by space, secured by time.

Chia (XCH) is a blockchain platform built by Chia Network that re-imagines how decentralised money can be created and used. Unlike traditional Proof-of-Work blockchains that rely heavily on compute power, Chia employs a unique Proof of Space and Time consensus mechanism—where wasted storage space is put to productive use, and a verifiable time component (via VDFs) ensures security and chain quality.
