# Proof of Utility (PoU)
If you are not deep into the blockchain space, terms like Proof of Work, Proof of Stake, or Proof of Utility might sound confusing.
The key thing to understand is what **Proof of Utility (PoU)** represents and why it is different. Instead of burning energy to solve meaningless puzzles like Proof of Work, or earning passive rewards just for locking up tokens like Proof of Stake, Proof of Utility rewards and incentivizes real, measurable work.
This model links token emissions directly to verifiable tasks such as images processed, deliveries completed, or hectares scanned. Contributors earn only when useful work is successfully verified, capturing the measurable and trackable value that robotics and AI applications generate.
On **Pulse AP**, this means completing compute tasks, storing data, or managing secure access operations. When a task is finished, it is verified and recorded on-chain, turning real work into blockchain-anchored proof of utility. That is how blocks are created and how contributors earn **$PULSE**.
It is a model designed to reward those who contribute tangible value to the network.
