PPC Peercoin Rank #1322

Peercoin (PPC) is one of the earliest cryptocurrencies, with its network having launched in 2012. It is notable for introducing proof-of-stake consensus to public blockchains, making it a pioneer in energy-efficient and sustainable blockchain technology. Inspired by Bitcoin, Peercoin shares much of its source code and technical foundation, including the SHA-256 cryptographic hash function, and is distributed under the MIT/X11 software license. Rather than imposing a hard cap on total supply, Peercoin is designed to converge on a long-term annual inflation rate of approximately 1%. A deflationary mechanism complements this design: the standard transaction fee of 0.01 PPC per kilobyte is burned rather than paid out, gradually reducing circulating supply over time. While proof-of-stake was once a distinguishing feature, the mechanism has since been adopted across much of the broader cryptocurrency industry. Peercoin itself supports smart contract functionality and is associated with both the Ethereum and Polygon ecosystems, positioning it as a base-layer blockchain focused on energy efficiency, low transaction costs, and long-term scalability.
