What makes Neo Different from others:
Delegated Byzantine Fault Tolerance (DBFT) algorithm — This is a consensus mechanism (instead of the traditional proof of work/stake) that allows the system to resist the Byzantine Generals problem and maintains consensus even if some nodes bare malicious intentions.
NeoX — This system will create the ability to execute and operate across various Blockchains.
NEO Contract — Is the mechanism for creating smart contracts seamlessly in scalable, high performance environments that integrates pre-existing codebases (e.g. C#, VB.Net, F#, Java, Kotlin).
NeoFS — This is a service which allows decentralized storage (like a peer to peer Dropbox).
NeoQ — A lattice-based cryptographic mechanism which creates problems that cannot be solved by quantum computers and ensuring being quantum-proof.
