Bitcoin Interest is a fork of the Bitcoin protocol that pays coin holders interest. Bitcoin Interest (BCI) allows users to securely earn interest payments without ever moving coins from their wallets. Bitcoin Interest's developers believe that paying interest, weekly or monthly, on inactive crypto-funds can benefit the entire cryptocurrency market by reducing volatility.
Bitcoin Interest (BCI) is the first cryptocurrency protocol to use the ProgPoW consensus algorithm. ProgPoW is a Proof-of-Work algorithm designed to reduce the centralizing tendencies of ASIC mining by making it easier for standard GPU devices to participate in the mining process.

Nano, formerly known as Railblocks, is a cryptocurrency that is focused on enabling fast transactions with no fees. Nano's innovative blockchain architecture utilizes a block lattice structure that does not need miners to confirm transactions.
Nano uses a Delegated Proof-of-Stake consensus.
