Myriad is a cryptocurrency that supports 5 algorithms for ASIC, GPU, and CPU mining. These algorithms include SHA256d, Scrypt, Myr-Groestl, Argon2d, and Yescrypt. By utilizing a multi-algorithm approach, Myriad provides resistance against 51% attacks as it would require different hardware to control 51% of the blocks. Additionally, Myriad supports merge mining on the SHA256d and Scrypt algorithms, allowing it to benefit from the hashrates of other coins like BTC and LTC.
