University of Cambridge to launch decentralized carbon credit marketplace on the Tezos blockchain

Published at: Nov. 10, 2021

In an announcement Friday morning, the University of Cambridge announced it would be building a novel decentralized carbon credit marketplace to support global reforestation efforts. Its ultimate goal would be to increase the adoption of nature-based conservation solutions, or NbS, such as reforestation, through financial instruments. The institution envisions that purchasers of carbon credits will be able to securely and directly fund NbS projects through the platform.

The initiative, known as the Cambridge Centre for Carbon Credits, or 4C, is based in the Department of Computer Science and Technology and the Conservation Research Institute. Scientists and researchers will build the marketplace on the Tezos (XTZ) blockchain. Tezos is a smart contract blockchain that enables users to vote on governance protocols put forth by developers. The network is known for its eco-friendly nature.

Earlier in the year, Tezos developers tweeted that minting three nonfungible tokens, or NFTs, on the Tezos blockchain produces .00054 lbs of carbon dioxide, compared to 915 lbs of CO2 for the same NFTs minted on the Ethereum (ETH) blockchain.

Minting three #NFTs on #Ethereum produces 915 pounds of carbon dioxide emissions, the weight of a polar bear. On #Tezos it produces .00054 lbs - about the mass of the snowflakes on this bear’s snout. #TezosCleanNFT #CleanNFT pic.twitter.com/mlSKouCSdE

Anil Madhavapeddy, 4C's director, issued the following statement regarding the technological development:

Current accreditation systems that measure and report the value of carbon and related benefits like biodiversity conservation and poverty reduction rendered by NbS are costly, slow, and inaccurate. These systems have undermined trust in NbS carbon credits. What is needed is a decentralized marketplace where purchasers of carbon credits can confidently and directly fund trusted nature-based projects. And that’s the gap the Centre is aiming to fill.

Crypto wallets: An important battlefront to gain wallet share and mind share
Digital wallets are software constructs that mimic physical wallets and provide the functionality of storing, using and categorizing payment instruments. The journey of digital wallets started with payments and morphed to other forms of stubs such as digital passes, tickets and boarding passes. However, crypto wallets attempt to redefine the digital wallet landscape as something more than safe storage of payment and crypto instruments. With more than 100 crypto wallets and growing, this sector in the cryptosphere is getting crowded and adding further complexity to an already fragmented blockchain and digital asset space. As I study this space and try …

Enegra migrates digitized equity tokens from Ethereum to Polygon blockchain
Enegra Group, a commodities trading firm based in Malaysia with a net asset value of $28 billion, has migrated its equity-tied EGX security tokens from to the Polygon (MATIC) blockchain from Ethereum (ETH). In 2019, Energra tokenized 100% of its equity, enabling shareholders to digitally exercise their dividend, voting, and governance rights. Both the initial tokenization and token migration were facilitated by Tokeny, an asset tokenization and compliance infrastructure provider. Matthew Averay, managing director and CEO at Enegra, said: We tokenized our equity to improve liquidity. And, now that the technology is available for faster, cheaper, and compliant transactions on …
