The latest draft of the European Union’s (EU) proposed legislative framework for governing virtual currencies, Markets in Crypto Assets (MiCA), still contains a provision that could limit the use of proof-of-work cryptocurrencies.
Proof-of-work is the energy-intensive consensus mechanism that underlies popular cryptocurrencies like bitcoin and ether. The computing process has come under heavy scrutiny from lawmakers in the EU over energy concerns.
The EU parliamentarian in charge of the MiCA legislative framework, Dr. Stefan Berger, said at the time that the paragraph in question had been removed, but that a final decision had not yet been made.
One version of the new draft, reviewed by CoinDesk, has a similar provision though significantly toned down from the original. It says that crypto assets “shall be subject to minimum environmental sustainability standards with respect to their consensus mechanism used for validating transactions, before being issued, offered or admitted to trading in the Union.”
If a proof-of-work consensus mechanism is operating on a small scale, it is exempt from having to meet sustainability standards, according to the provision. What qualifies as a small-scale operation has yet to be determined.
It also says that energy-intensive crypto assets that are already in use in the EU before the legislation comes into effect, will have to “set up and maintain a phased rollout plan to ensure compliance with such requirements” as specified in another part of the framework.
Another version of the measure, also seen by CoinDesk, would soften the language even further. However, it’s believed the stronger version has a lot of support among parliamentarians.
Although there are plans to move Ethereum from proof-of-work to a less energy-consuming consensus mechanism called proof-of-stake, it is unclear how bitcoin, the largest global cryptocurrency by volume traded, could transition from proof-of-work. So while there’s been a huge push as of late to use renewable energy in bitcoin mining, the industry is still very much dependent on traditional energy sources, thus making the cryptocurrency potentially vulnerable under the stronger proposal.
The crypto community has been swift to react, with some calling on citizens in the EU to contact their parliamentarians to oppose the measure.
Ledger, a crypto hardware wallet provider, issued a statement saying:
Individuals and organizations should be free to choose the technology most appropriate to their needs. Policymakers should neither impose nor discriminate in favor of a particular technology. This is deeply concerning and would have serious consequences for Europe.
Once again, we are going against the History. Once again, we are leaving opportunities to others while boasting of having a good regulation. If this text passes as it stands, we will pay the price in terms of our competitiveness and the interests of European citizens.
The EU parliament is set to vote on the latest MiCA draft on March 14.
