Peercoin

Peercoin is one of the earliest cryptocurrencies, launched in 2012. It introduced the proof-of-stake consensus, making it a more efficient and sustainable public blockchain technology. Unlike Bitcoin, Peercoin does not have a maximum supply, aiming for an annual inflation rate of about 1%. Peercoin focuses on security and decentralization, developing second-layer solutions for enhanced functionality, speed, and cost-effectiveness in transactions.
