# Proof of Meaningful Work (PoMW)

While the basic idea, to protect the Blockchain by proving that a certain amount of computation was invested to create every single block, is worth being preserved, the current implementation, using purely artificial computational tasks (hashing), with the sole goal of burning “enough” energy, is much too wasteful to be used productively1 and scales very badly. Proof of Meaningful Work keep the good idea, but implement it using meaningful computation tasks, so that the energy invested in the proof of the miners’ computational strength is used for calculations that support public scientific research projects (e.g. medical research for cures, chemical research, astrophysical simulations).

Here below combined with PoS so the ratio of PoS to PoMW can be adjusted continuously according to the momentary load situation.

## Pros

* Decrease wasted energy. The needed energy will be used for socially responsible projects in the fields of healthcare, science, ecological protection and more.

## Cons

* attack of more than 50% of the total computing power

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://tokens-economy.gitbook.io/consensus/chain-based-proof-of-work/proof-of-meaningful-work-pomw.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
