Let's take a look at each element in our system:
ACE and ECS are world-leaders in developing advanced biomass cookstoves. The hardware included on these stoves measures and records the stove usage through several parameters: burn time, fan usage and geolocation. These measurements can be used to calculate the amount of carbon emitted.
As the stove collects data, it automatically 'batches' that data to be sent to the data verification nodes. Prior to being sent, the data is cryptographically signed by the stove hardware to ensure that the data cannot be tampered with throughout the rest of the process.
Alongside developing stoves, both ACE and ECS sell efficient, low-carbon advanced biomass pellets as an improved fuel choice. Based on the UNFCC methodology, the TelCo-based sales data can be used as a proxy for stove usage data - meaning that we could produce carbon offsets using just this data. However, we want to go the extra mile and combine this with the stove data to create ultra-hard data-backed offsets.
The stove data combined with the fuel transaction IDs, are then sent to validating nodes. These nodes perform a sequence of checks to ensure that the data backing tonnage is valid:
Data integrity - The first check compares the signature provided against the stove address and determines whether the data has indeed come from a verified stove.
Authenticity checks - This series of checks looks at the data itself and whether the same, or similar, batch of data has been previously submitted. This set of checks also compares geolocation data to ensure that stoves are not being used specifically to farm income from stove usage.
Methodology calculations - The final checks perform the necessary calculations against the baseline scenario to calculate the amount of CO2e mitigated in using the advanced cookstoves with biomass pellets.
A common feature in the traditional carbon verification process, this buffer pool will allow individuals to inspect the metadata behind a carbon tonne, as well as allowing people to leave comments, report issues on the ground etc.
An automated proof providing clarity and on the decision made following the 30 day buffer window is pinned to IPFS for the sakes of transparency in the verification process. Individuals can use this information to appeal decisions or identify individuals attempting to exploit the system.
After successfully passing through the 30 day buffer pool, a batch carbon NFT is minted consisting of the number of carbon tonnes represented as well as the associated metadata. Comments made during the buffer pool will also be included within the NFT's metadata.
In partnership with C3 we aim to allow NFT owners to fractionalise the batch into individual, fungible tons, represented by ERC20 tokens.
