Unibright and Zühlke Engineering launch Carbonara: Compensation of Blockchain related CO2 emissions

The Carbonara Coinpensator is a blockchain related open-source project, established by Unibright and Zühlke Engineering. The main goal of the project is to raise awareness of the energy consumption of public blockchains.

Blockchain, as a technology, is still finding its way to mass adoption. Starting with the blockchain based cryptocurrency Bitcoin in 2009, the ecosystem around blockchain has evolved ever since, generating a wide range of protocols, applications, implementations, consulting providers and many other roles and players.

Still, in 2019, the best-known application for blockchain is cryptocurrencies — and among the most famous ones, Bitcoin and Ether are under the reputation to be implemented on protocols that are very energy consuming.

It is not an easy task to give an exact answer to the question “How much energy did my blockchain transaction consume?”, as the calculation is dependent on a large number of parameters, of which the majority can only be estimated.

Unibright and its partner Zühlke Engineering have joined forces to answer this question with Carbonara, a dedicated side-project featuring Unibright developers, Zühlke engineers, and third party participants such as team members of eth.events.

There are three key motivations for working on this project:

  1. Creating knowledge around blockchain energy consumption
  2. Incentivizing the future of blockchain to be more energy-conscious and sustainable
  3. Inspiring individuals to contribute to CO2 compensation projects

Unibright and Zühlke will continue supervising the Carbonara project and its enhancement. Yet, the long-term benefit of Carbonara will be dependent on the participation of willing individuals, research groups, partner portals and companies.

The complete code for Carbonara is open-source and publicly available at https://github.com/carbonara-coinpensator

We are asking developers and the community to spread the word and help Carbonara on:

  • providing improved data for all parts of our calculation
  • providing data and calculation on protocols other than Bitcoin
  • including the Carbonara backend on your blockchain explorer
  • integrating Carbonara with your compensation project
  • writing articles, tweets, interviews or blog entries on Carbonara
