A "Wormsbox" (worm node) represents the number of earthworms (Eisenia foetida) needed to process the organic waste generated by one person daily, capturing a specific amount of carbon. This concept is aimed especially at the citizens of Mexico City, where the project is beginning. The mission of the Wormsbox is to compost and scale up this process, reaching the first thousand Wormsboxes, which would equate to capturing a certain amount of CO2 per year. We aim to develop a methodology that can decentralize the process, allowing its implementation anywhere in the world, as earthworms are common animals in various regions globally. We use web3 to maintain an active and transparent record of each Wormsbox to account for the CO2 we are absorbing and to know at all times where we can harvest and plant more Wormsboxes in cities, creating a decentralized community that increases its carbon capture every time it cares for its Wormsboxes.
