In order to get the ANOMs/NOMs pass through the Bonding Curve instruction.
Delegation is lending your tokens to one or more validators in order to take part in the consensus. Delegators share both - revenue and risks with validators. Validators share their revenue with their delegators. Validators may apply a commission, or a fee before they distribute the profits to the delegators as well. On the other hand, if a validator misbehaves (Such as not signing enough blocks in a sliding window or double signing the blocks), validator's and their delegator's funds might be slashed.
Not everyone is able to join the network as a validator, these people can still be part of the consensus as delegators and get return on their investment.
In order to delegate, you need to send a delegate transaction.
