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.

DigiByte is a a blockchain platform that places an emphasis on security and block speed. DigiByte has one of the fastest block speeds of any public blockchain and uses an innovative consensus protocol with 5 mining algorithms. This prevents mining centralization and also minimizes the chances of security breaches. DigiByte transactions are limited in size and scope to increase speed, efficiency, and throughput.
DigiByte hopes that these innovations will provide the ideal blockchain infrastructure for a range of applications within the IoT and AI fields, that require a high degree of security and fast block speeds.
