Prizm is a 100% proof-of-stake (PoS) cryptocurrency, based on Next core, constructed in open-source Java. Prizm’s unique proof-of-stake algorithm does not depend on any implementation of the “coin age” concept used by other proof-of-stake cryptocurrencies, and is resistant to so-called “nothing at stake” attacks. A total quantity of 10 million available tokens were distributed in the genesis block. Curve25519 cryptography is used to provide a balance of security and required processing power, along with more commonly-used SHA256 hashing algorithms.
