PEER COIN?

Peercoin, also known as PPCoin or PPC, is a peer-to-peer cryptocurrency utilizing both proof-of-stake and proof-of-work systems. Peercoin is based on an August 2012 paper which listed the authors as Scott Nadal and Sunny King. King, who also created Primecoin, is a pseudonym.

Namecoin provided a platform for decentralized DNS services, while Peercoin (PPC) was the very first PoS cryptocurrency. Besides these unique characteristics, both coins have faded into obscurity. ... Since these coins are not dead, they will probably pump again when the next big crypto rally comes.

Most people buy Peercoin, as well as other cryptocurrencies, as an investment. Although the coin hasn't increased in value as much as Bitcoin and a few others, it has proven to be a great investment so far — but only if you bought it early. If you invested $1,000 in Peercoin in June 2011, you would have $23,000 today.

Efficient Security
Peercoin (PPC) first came online in 2012, making it one of the earliest pioneering blockchains. The key innovation of Peercoin is its invention of proof-of-stake, an alternative consensus protocol to Bitcoin’s proof-of-work.

Proof-of-work blockchains are secured by proving the consumption of a costly limited resource: electricity. Proof-of-stake replaces this expensive security protocol by utilizing an alternative scarce resource: time.

Due to the cost efficient nature of proof-of-stake’s time based consensus rules, Peercoin is capable of allowing any network connected computer to participate in the blockchain’s security process. This efficiency strengthens Peercoin by growing the number of security providers and ensuring that security can be sustained over the long-term.
