Introduction

If you are new to the Cybertensor developer ecosystem read this section first before proceeding to participate in the Cybertensor network.

:::tip looking for a non-technical introduction to Cybertensor? See Questions and Answers. :::

The Cybertensor ecosystem consists of the following three components (refer to the above diagram):

An incentive-based competition mechanism: You can either create your custom incentive mechanism for your own competition or join a competition that already exists in the Cybertensor ecosystem. Each such incentive-based competition market is called a subnet. Subnets constitute the core of the Cybertensor ecosystem.
A blockchain that runs the above subnets and supports their proper functioning so that the incentive-based competition market is decentralized, is permissionless and is collusion-resistant, i.e., is resistant to market manipulation.
The Cybertensor API that connects all the essential elements within the above two components, and also connects the subnets and the blockchain.

:::tip Open source tools and documentation Cybertensor provides all the open source tools, codebase and the documentation, with step-by-step tutorials and guides, to enable you to participate in the Cybertensor ecosystem. :::

Participating in Cybertensor ecosystem

You participate in the Cybertensor ecosystem by participating in a subnet.

How a subnet works

Subnets exist to operationalize the incentive-based competition mechanisms. See the below diagram.

Here is an explanation of the primary components of a subnet. Note that this explanation is highly simplified, and is intended only to convey the essential conceptual core of the subnet.

The item numbers below correspond to the numbers in the above diagram.

A subnet is defined by the incentive mechanism it supports. The incentive mechanism is unique to the subnet.
Entities in the subnet, called subnet miners, each perform a useful task, i.e., solve some problem, as defined in the incentive mechanism of the subnet.
Separate entities in the same subnet, called subnet validators, each independently evaluate the task performed by the subnet miners.
The subnet validators then each express their opinion on the quality of the miners. These opinions of the subnet validators are then provided as a collective input to the Yuma Consensus mechanism on the blockchain by using the Cybertensor API.
The output of the Yuma Consensus mechanism from the blockchain will then determine how the rewards for the subnet miners and subnet validators are to be distributed. The rewards are in the form of PUSSY tokens.

When you participate in the Cybertensor ecosystem, most of your activity occurs within the subnet you participate in. This is true whether you created your own incentive mechanism, i.e., your own subnet, or joined an existing subnet either as a subnet validator or as a subnet miner. Nevertheless, you can interact with other subnet entities.

You can use Python with the Cybertensor API to write your incentive mechanism.

Cybertensor personas

You can participate in the Cybertensor ecosystem as the following personas:

Subnet owner: When you only want to create a subnet but transfer the tasks of operating the subnet to others.
Subnet validator: When you are responsible for running the subnet validator.
Subnet miner: When you are responsible for running the subnet miner.
Blockchain operator: When you run the blockchain. This mostly applies during the offline testing of your subnet and your incentive mechanism, when you need a local emulation of the Cybertensor blockchain because you are disconnected from the Cybertensor network.

Participating in a subnet

When creating a subnet you should always start by first developing and testing the subnet incentive mechanism **locally **, then connecting to the Cybertensor testchain and finally go live by connecting to the Cybertensor mainchain. See the below conceptual deployment diagram showing the three stages.

Testing the incentive mechanism means running one or more validators and miners to ensure that rewards are distributed in the intended way.

:::tip Before you participate in a subnet We recommend all subnet participants to become familiar with the incentive mechanism before joining a subnet or creating a new subnet. :::
