# Ultra-Small World Network Topology
At the core of the Mandala architecture is an **ultra-small world core node network** of Teranodes, which is essential for delivering operational efficiency, security, and speed. A **Small World Network** is a network topology optimized for the rapid dissemination of information, minimizing the number of hops required to synchronize the entire network. This characteristic is vital for optimizing the propagation of transactions from the network's edge to the core mining nodes.
This central topology forms a complete graph among the Teranodes, enabling them to disseminate transactional and block information swiftly while simultaneously verifying other Teranodes' block proposals. This capability allows the network to process millions of transactions per second, **significantly reducing the risk of double-spend attacks** and **distributing the read load** across Overlay Services, thereby **enhancing resilience**.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://hub.bsvblockchain.org/higher-learning/bsv-academy/bsv-network-topology/essentials-of-bsvs-mandala-network-architecture/ultra-small-world-network-topology.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
