The function of the axon is to transmit information to different neurons - Wikipedia

---

Axon is a multi-user, multi-neuron management canister.

Overview

• An Axon canister controls one or more neurons
• Axons can have one or more owners
• An approval policy can be set, eg. 3 out of 5 owners required to approve an action
• Requests like ManageNeuron are sent to Axon, which queues them for approval
• A snapshot of owners and current policy is stored with each request
• Once the policy conditions are met, the request is forwarded to all controlled neurons
• Axons can be public and expose all neuron data

Usage

Deploy an Axon canister:

dfx deploy Axon --argument 'record {owner= (principal "your-principal-here"); visibility= variant{Public}}'

Currently, canisters cannot control neurons or hold ICP. It is only possible to add the Axon canister as a hot key for neurons, so only commands like Follow and RegisterVote will succeed.
