# Model spreadsheet

All metrics are into the spreadsheet actually, some need more accurate data
https://docs.google.com/spreadsheets/d/1Qyn6vIyJ4yMiWej0joYyZd4dM4nv-aOiTtVXDXvm5hA/edit?usp=sharing

# Calculator inputs

<h1>Main metrics reqiured</h1>

* Kodadot transactions
- [ ] Target number of transactions

* Kodadot collators
- [ ] Targer number of validators
- [ ] Average cost for a validator server (ponderate between home server, VPS and bare metal hosted)

* Kusama & Polkadot validators
- [ ] Targer number of validators
- [ ] Average cost for a validator server
- [ ] Estimate of % worktime dedicated to a single parachain (depending on number of parachains deployed)

 
- What's carbon footprint storing files on IPFS and Arweave? Per kB?

### Kodadot metrics requests
#### most important metrics
- number of NFTs
- (average) storage of NFTs

#### good to have metrics
- numbers of trades per NFT
- account number of BURNed NFTs
- account how much costs actions
    - MINT
    - SEND
    - CONSUME
    - LIST

### Kodadot implementation
- we could put in sustainability toggle if artist want to cover Carbon Offset and then we can mark it as Carbon Neutral/Carbon Negative NFT

### Kodadot profile on offsetra
- like https://offsetra.com/profile/cryptovoxels 
- signuped like yangwao@kodadot.xyz

### OTC notes on green positive reinforcment

- Jam's drop
  - We can talk to registrars about a custom field
  - Koda could display the status of the custom field

Could be nice also to allocate in the ecosystem local green  projects connected to local kusama nodes , where the nodes have also the responsability to validate them and to manage if the project is REAL and they are effetively doing things happen. For example: I'm a local node here as ambassator and in the association there is a local project for planting trees that need some gas to run, so i will validate them in the plattform and for a certain time comprove that they are real doing it !

We can comprove with images (for example) of them plating trees and mostly important care for them for a certain periodo of time , and post the images in the platform inviting others to donate.
Because on the thematic planting trees the most important is to care for them dont let them die, i had this experiencie in the past with groups of people to plant trees and lots of people plant but didn't really care about them it's why we need i kind of validators that certificate that the trees are healthy*


I guess there is lot of ways how it could be offset carried
- user transactions
- treasury
- validators themselves
- housing
- provider for datacenterum


# CO2 costs of
