Peercoin $PPC

Peercoin is a pioneering cryptocurrency project launched in 2012. It is recognized for inventing the proof-of-stake consensus mechanism, positioning it as the foremost efficient and sustainable public blockchain technology. Inspired by bitcoin, Peercoin shares much of its source code and technical implementation with the original cryptocurrency. Unlike Bitcoin, Namecoin, and Litecoin, Peercoin doesn't have a hard cap on the number of possible coins and is designed to achieve an annual inflation rate of 1% eventually.

Key Features of Peercoin

Peercoin stands out in the crowd with its unique features. It utilizes the same cryptographic hash function as Bitcoin (SHA-256), but with far greater energy efficiency—100 times more, to be precise. Transactions in the Peercoin network are faster and cheaper. One of its defining features is the deflationary aspect, as the transaction fee of 0.01 PPC/kb paid to the network is destroyed. This feature, combined with increased energy efficiency, aims to provide enhanced long-term scalability.

Challenges and Competition

Despite its innovative approach, Peercoin faced fierce competition in the cryptocurrency market. Various other cryptocurrencies that emerged in 2014 and 2015 outperformed Peercoin in numerous crucial aspects. For instance, DASH offered anonymity which Peercoin couldn't, and Dogecoin's transactions were faster and cheaper compared to Peercoin. Furthermore, Peercoin's advantage of PoS technology was overshadowed as it began to be adopted by other cryptocurrencies, causing Peercoin to lose some of its initial user interest.

The Philosophy and Future Goals of Peercoin

The Peercoin Team is committed to preserving and maximizing decentralization to increase network security. They believe in developing most features and technologies on top of the blockchain rather than directly into the blockchain protocol. Thus, they focus on developing second layer protocols and sub-networks that interact with the base layer blockchain to improve functionality, including tokens, smart contracts, and high-speed low-cost transaction processing. The vision for Peercoin is to act as a secure and censorship-resistant base layer for the future blockchain-connected world.
