Starcoin is a decentralized hierarchical smart contract network. It aims to provide a secured digital asset and a decentralized financial operation platform so that the blockchain can be applied in more fields with a lower threshold. Security is the foundation of the blockchain. Starcoin has taken security as the primary goal from the beginning of its design. To ensure the security of digital assets, it has conducted in-depth exploration and improvement from multiple levels such as the base layer, consensus layer, protocol layer, extension layer, and application layer.

Starcoin is a new generation of public blockchain infrastructure, a hierarchical, decentralized blockchain system.

• Layer I of Starcoin focuses on providing the basic capabilities for producing, managing, and trading digital assets, with which users can define assets safely and quickly and flexibly perform asset transfer and exchange with the help of smart contracts.
• Layer II of Starcoin focuses on addressing the scalability and performance issues during the transfer and exchange process of digital assets. Due to the unique design of Starcoin, the Starcoin Layer II can use the data of Layer I, and Layer I can also verify the calculation results of Layer II. Both Layer I and Layer II are organically combined, and the digital assets can circulate freely between the two layers.
