# 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 *-Pedro Marques (lightsonestudio)Drop: Pedro Marques, [31.03.21 09:39] 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 - validator - RPC node - chain - single system.remark - runtime calls # Resources - https://github.com/kylemcdonald/cryptoart-footprint - https://carbon.fyi - https://www.cloverly.com/ - https://medium.com/tqtezos/proof-of-work-vs-proof-of-stake-the-ecological-footprint-c58029faee44 - https://www.notion.so/Offsetra-Knowledge-Base-d06ed4569364417998581b6bd726d319 - list of kusama validators https://telemetry.polkadot.io/#list/Kusama
