Contents holds the wiki’s reference articles on Radix: how the network works, how it got here, and material people use alongside it. Developer guides live under [Developers](/developers), projects built on Radix under [Ecosystem](/ecosystem), and essays under [Blog](/blog).

Tech covers the protocol itself. Core concepts explain the ideas Radix is built on, such as [atomic composability](/contents/tech/core-concepts/atomic-composability) and [sharding](/contents/tech/core-concepts/sharding); core protocols describe the running parts, such as the [Radix Engine](/contents/tech/core-protocols/radix-engine) that executes transactions and the [XRD token](/contents/tech/core-protocols/xrd-token) that pays their fees; releases record each network upgrade; research follows work that has not shipped; and comparisons set Radix against other ledgers.

[History of Radix](/contents/history) runs from Dan Hughes’s first prototype in 2013 to the network today, with the conferences, workshops and hackathons along the way. Resources holds practical material: [answers to common questions about Radix](/contents/resources/faq), how to buy XRD, the wiki’s brand assets and its MCP server for AI agents, its legal terms, and Python scripts.
