PAC coin, short for People’s Alternative Choice, is a cryptocurrency with a hybrid Proof-of-Work (PoW) and Proof-of-Stake (PoS) consensus mechanism. PAC Coin aims to encourage cryptocurrency adoption by improving usability and community governance. The network will rely on a system of masternodes to help verify transactions.

Sharechain is developing a Proof-of-Work cryptocurrency platform. Their network is currently fueled by the Ethereum-based SSS token. Their marketing materials are unclear and do not offer any information about its advantages.
