Peercoin initially used a hybrid consensus model that combines proof-of-stake (PoS) with proof-of-work (PoW). The PoW component was used to secure the network and prevent certain types of attacks, while the PoS component is used to validate transactions and create new blocks.

Peercoin offers users a more energy-efficient and environmentally friendly alternative to traditional cryptocurrencies. Its proof-of-stake (PoS) consensus algorithm also allows for faster transaction processing times and increased security.

You can buy, sell, and trade Peercoin on a few centralized cryptocurrency exchanges, such as MEXC. Its ERC20 version is also available on Uniswap and other DEXs on the Ethereum network.

To store Peercoin securely, use a reputable cryptocurrency wallet that supports PPC, including their own desktop wallet and its web version. You can also store PPC in a secure mobile wallet or a hardware wallet like Ledger or Trezor for added security.
