First, Doge Protocol will support multiple asymmetric cryptosystems (like Dilithium, Falcon) instead of just one that other blockchains use. This will give a higher degree of security, because the network can transition to another signature scheme if one has been found vulnerable in the future. Secondly, Doge Protocol will also allow private-key rotations and account rules, thus making accounts more secure. Quantum Resistance is only one of the key features of the Doge Protocol blockchain. Doge Protocol will also use a hybrid proof-of-stake consensus system that supports sharding, thus higher TPS and low txn fees. The details of this consensus mechanism will be given as part of the Consensus Whitepaper release next month. The other important feature is "satellite chains" that allows extensibility to support use-cases like decentralized file-storage.  For details, see vision paper at https://dogeprotocol.org/whitepapers/Doge-Protocol-Vision-Paper-1.pdf
