PIRL is a community based blockchain project focused on making cryptocurrencies more accessible. It was the first blockchain to introduce an Ethash-based masternode. Their goal is to develop a comprehensive DApps hosting infrastructure that will be easy to use. Their Poseidon platform is designed to be an on ramp for users without any technical knowledge. PIRL's multi-tiered masternode network has an ASIC-resistant Proof-of-Work (PoW) consensus mechanism, and is powered by the PIRL coin. The company plans on developing features, such as: decentralized file storage, messaging, and escrow services for payments.

NEM is a cryptocurrency and blockchain platform that allows multiple ledgers on the same blockchain. NEM Smart Assets are used to create mosaics for any asset. Transaction fees are paid with NEM's native currency, XEM. NEM originally began as a community-oriented cryptocurrency that was built from the ground up in the Java programming language.
NEM's goal is to achieve widespread distribution through improved scale and speed. It pioneered several blockchain features such as its proof-of-importance (POI) consensus algorithm, encrypted messaging, a unique reputation system, and multi-signature accounts.
NEM is also developing a commercial blocckahin called Mijin, that is currently being tested by several companies and financial institutions.
In early 2018, approximately $400 million worth of XEM were stolen from a Japanese exchange called Coincheck, that was the victim of huge hack. The exchange failed to implement proper security for this coin protocol, and the hackers only stole XEM coins as a result. Instead of creating a fork to deal with this issue, NEM set up an automated tagging system that flagged these funds. NEM then stopped tracking these stolen coins
