The environmental impact of crypto mining has long been a source of contention. As dynamic as it is, the industry is working to find a solution to this problem.
Thousands of computers worldwide are whirring away together, pounding complicated math problems that create and sustain bitcoin. However, this implies that the network is always consuming energy, which is a point of conflict for many bitcoin sceptics and critics.

Proof-of-work is a system in which computers compete to be the first to solve complex challenges. PoW mining secures the network by ensuring that only those who can prove that they have expended resources are awarded the opportunity to append new transactions to the blockchain.

Because of this feature, attacking a proof-of-work system like Bitcoin is difficult, time-consuming, and expensive. At the same time, PoW mining consumes a significant amount of electricity, raising serious concerns about the environmental impact of cryptocurrency.

With the EU aiming to achieve carbon neutrality by 2050, the future of energy-intensive proof-of-work Bitcoin mining seems uncertain.

A vote on the European Union's Markets in Crypto Assets (MiCA) legislation is scheduled on March 14th, following a debate over language that would have effectively banned bitcoin.

The MiCA bill has had its upsides and downsides, and market participants have frequently challenged the law's content. However, after revising certain aspects of the bill, European Union parliamentarians are due to vote on the MiCA bill on March 14th, which might have an impact on how crypto businesses are taxed in the region.

The previous version expressed reservations about crypto firms that provide services employing Proof-of-Work. However, in February, European Union lawmakers unanimously opted to withdraw the provision of the MiCA bill that would have made PoW cryptos, such as Bitcoin and Ethereum, unlawful.

Dr Stefan Berger, the member of parliament in charge of MiCA, stated through Twitter that an independent discussion of the PoW is no longer on the table. He said that it makes it logical to treat cryptos like any other financial item in the taxonomy.

Although not explicitly mentioned, the measure would directly impact proof-of-work (PoW) chains. The Bitcoin network, Ethereum, and several other crypto assets use the PoW consensus mechanism. The new clause, which replaces the controversial line on the "minimum environmental sustainability" of crypto mining, will compel blockchain operators to submit a develop an extensive plan outlining how they will achieve environmental sustainability compliance. Failure to submit a plan may result in coins being banned from being mined or traded in the EU.

However, in terms of environmental impact, even while this appears to be a considerable amount of energy to consume for a cryptocurrency, Bitcoin supporters maintain that this figure is less than 10% of what the traditional banking system uses. The enthusiasts also claim that a big portion of the energy consumed by cryptocurrency originates from renewable sources and that Bitcoin mining consumes a significant quantity of energy that would otherwise be wasted.

Citi's co-head of digital assets quits to start a crypto venture

Alex Kriete, co-head of digital assets at Citi, resigned from the banking behemoth on Thursday via LinkedIn after 11 years with the company.
