Topline: EMURGO Africa, Cardano’s commercial arm on the continent, has invested $250,000 in the environmental credit exchange company Changeblock. (Details)
Quick facts: In a press statement, the Cardano affiliate noted that its investment aimed to promote sustainable development and environmental responsibility, especially in the carbon exchange market.
Of note: Changeblock employs blockchain to facilitate carbon credit trading, enabling companies that surpass emissions limits to counterbalance their excesses by acquiring credits through emission-reduction projects.
Why this matters: Carbon credits are becoming vital for offsetting emissions. They’re bought from projects that reduce carbon, like tree planting. Some better-known carbon trading projects include Anew, Ecologi and Finite Carbon.
- However, verifying the legitimacy of carbon credits is challenging, and blockchain have been tipped to provide the missing transparency.
- A few African projects are looking to use blockchain to record every credit’s journey immutably, potentially enhancing credibility and preventing fraud. Shamba Network is another example of a blockchain-based carbon trading project.
Angola moves to regulate virtual assets and ban cryptocurrency mining

Topline: The Angolan government is preparing a bill to regulate digital assets and ban cryptocurrency mining activities in the country. The bill seeks to protect the country from the purported environmental hazards commonly associated with crypto mining. (Details)
State of play: According to an official statement from the President’s office, the proposal to ban crypto mining stems from the need to protect the national electricity system, considering the high consumption of infrastructures in the activity of mining cryptocurrencies
- In addition, the country wants to limit the circulation of digital currencies and tokens not issued by the country’s central bank.
- Angola’s minister of finance, Vera Daves, said that the bill would bring virtual assets under the regulation of the country’s Capital Market Commission (CMC).
Essential background: While cryptocurrency in Angola is not illegal at present, the government has previously warned against transacting with bitcoin and others and restricted financial institutions from dealing with them.
- In 2021, the country was ranked third among countries with the most crypto-mining operations in Africa. On the other hand, the rise of bitcoin mining has triggered environmental concerns in Angola.
- Earlier this year, the country’s Criminal Investigation Service detained seven Chinese nationals for mining crypto from a camouflaged brick factory. They were accused of using enormous amounts of electricity from the public distribution system to mine cryptocurrencies.

African-Centered Innovation: Samples emphasized that Africans are best suited to understand the needs of their continent.
- She stressed that Africa is no longer just a recipient of innovation. It is generating its own solutions, particularly in the crypto space, and is uniquely positioned to address its financial inclusion challenges.
