Raptoreum is a proof-of-stake/proof-of-work hybrid blockchain that says its goal is to solve real-world issues in ways to help drive adoption and bring about a positive global change. The open-source project is also aiming to provide an asset platform allowing tokenization while also allowing DAPPs to work alongside smart contracts which are stored and executed at the node level. Raptoreum was founded back in 2018 and had been in Testnet/Development for nearly 3 years before Genesis block on February 26th, 2021. The RTM coin uses a custom hashing algorithm called Ghostrider. Ghostrider randomly switches algorithms with the aim of discouraging mass ASIC & FPGA mining which the project says is to increase overall decentralization.
