@SiuChingPong-AsukaKenji- it's just a way to view the security of Ethereum -- the way the signatures are generated means they only offer 128 bit security, due to the group/elliptic curve used (secp256k1), so I think the reasoning is th hash could be 256 bit or 160 bit or 129 bit but the elliptic curve will still be attacked/broken first. Add the EPEL Repository.
