Viacoin is an open source cryptocurrency based on the Bitcoin protocol. Viacoin has a 24 second block time and relatively fast transaction times. It can handle 175 transactions per second without scaling through Segwit or the Lightning Network. The fast transaction times make Viacoin a good option for sending micropayments. The platform also enables users to perform cross-chain atomic swaps between different cryptocurrencies, without a centralized exchange. Viacoin has an Auxiliary Proof-of-Work (AuxPoW) consensus mechanism that allows miners to mine multiple coins, that use the Scrypt algorithms, at the same time. Viacoin's smart contract platform, Rootstock, is compatible with Ethereum smart contracts.

Global Currency Reserve is a Proof-of-Stake (PoS) cryptocurrency built on a native blockchain. Its core infrastructure has similarities to Bitcoin, Peercoin, NovaCoin and BlackCoin. Global Currency Reserve's focus is on providing fast transactions times with minimal fees.

PLATINCOIN is a Proof-of-Stake coin that is minted instead of mined. Users participate in managing the network by renting hardware space from the project organizers for a period of 36 months. These computing resources will drive the PoS consensus, and the users that rent the hardware will be rewarded with newly minted PLC coins.
