Peercoin seeks to be the most secure cryptocoin at the lowest cost, by rewarding all users for strengthening the network. Peercoin is one of the truly unique alternative coins. Although its code is based on Bitcoin, Peercoin is the first coin to introduce Proof of Stake to secure the network. Proof of Work is also used in Peercoin, to promote fair coin distribution, but is not necessary for the security of the network. Thanks to increased mining participation, Peercoin inflation rate has consistently remained below 5% for the first half of 2014. At the current adoption rate, this rate will decline further over time, making Peercoin less inflationary and more sustainable than most other cryptocoins. When the entire money supply grows due to the minting process, all Peercoin holders who participate in minting maintain their relative share of the network. Although large stakeholders generate a higher total number of Peercoins, they cannot, in percentage terms, pull ahead of other minters.
