What is DFINITY's subnet? | Different "DFINITY" word stickers

Subnets are the fundamental building blocks of the entire DFINITY Internet of Computers, responsible for hosting different subsets of software containers. Subnets are created in a manner controlled by the Network Neural System (NNS) and bring together hardware resources from different data centers.

In terms of security, DFINITY's Byzantine fault-tolerant technology and encryption algorithm can ensure that the subnet is tamper-proof and unstoppable. At the same time, the subnet is transparent to users and software, and only needs to know the container's identity and function signature to call its shared functions.

In terms of scalability, if the performance of the subnet cannot carry the increasingly prosperous ecological applications. Then NNS can add subnets and new data centers to achieve unlimited expansion capabilities.
