# What is Proof of Work?

[*Proof-of-Work*](https://en.wikipedia.org/wiki/Proof_of_work) is a guarantee of invested energy - it serves as a foundation for the *honest signaling* *for the relevance of data*. Without honest signaling, we are susceptible to misallocating our attention to irrelevant information. Proof-of-Work as a signal guides our energy and attention in the right direction. <br>

Furthermore the energetic cost necessary to perform work prevents automated adversarial users from clogging the system with cheap spam. Bitcoin relies on Proof-of-Work for its security. OP\_NS uses the same cryptographic[ Proof-of-Work principles as Bitcoin](https://en.wikipedia.org/wiki/Proof_of_work#Bitcoin-type_proof_of_work).

**Data that holds proof of invested work (energy) is more worthy of our attention and should be highlighted**. Proof-of-Work allows us to effectively allocate our attention and enables a frictionless creative data economy.
