Vertcoin is a cryptocurrency with a strong emphasis on keeping the ecosystem as decentralized as possible. Vertcoin was designed with the goal of being easily mined by all users and to resist the centralizing tendency of specialized mining operations. Vertcoin has a Proof-of-Work (PoW) consensus mechanism that is ASIC resistant, and uses the Lyra2RE mining algorithm.

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.
