Symbol platform is a blockchain development ecosystem which focuses on creating a faster and more efficient blockchain projects. Symbol has neat built-in features such as plugin for business needs, which simplifies the lengthy process of having to build from scratch. To connect with Symbol, developers have the option of using hybrid blockchain system where they can create their own private blockchain and seamlessly connect with Symbols public blockchain. Security-wise, rather than using smart contract, Symbol utilise contract plug-in framework which makes it more resilient against human error and network attacks. XYM on the other hand, is the native currency for the Symbol public blockchain which is used to pay transaction. Some of the transaction fees will be allocated to public nodes that harvest the blocks, to ensure a sustainable ecosystem.
