$SYS Syscoin is a blockchain-based cryptocurrency with a set of smart contracts that have been thoroughly tested and built on a Bitcoin script system that has been extensively tested using OP1 to OP16 standard script opcodes. It can represent colored coin transactions, controlled by the distributed consensus logic of each smart contract's enforcement layer, while still maintaining backward compatibility with the Bitcoin protocol. These contracts can be combined to form building blocks for blockchain-based e-commerce solutions.

Syscoin's enhanced smart contracts contrast with Turing-complete smart contracts, which, by definition, are not enhanced due to the open nature of the underlying scripting language. Compared to traditional e-commerce applications, some businesses that want to leverage blockchain technology to improve efficiency and seek secure solutions find that the best approach is to try using immutable enhanced services, subject to regression testing, white-box and black-box testing, and employing rules specifically tailored to the application. These businesses also tend to choose the most robust network (currently the Bitcoin network). Syscoin combines these two functionalities, making it the best choice for users.
