A previous draft of the MiCA framework contained a provision that proposed a prohibition of cryptocurrencies that relies on environmentally unsustainable proof-of-work consensus mechanisms starting from January 2025.
The provisions were ultimately stripped, but according to statements made over the weekend, a more ‘watered-down provision’ appears to have been included once again.
A compromised version, also dubbed 'v9' states 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."
However, if the proof-of-work consensus mechanism is operating on a small scale, it's exempted from having to meet sustainability standards. But, what qualifies as a small-scale operation is yet to be determined.
The newly released version of the Markets in Crypto Assets (MiCA) report has resulted in more pushback from the crypto industry.
On Friday, crypto hardware wallet company Ledger 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."
Pierre Person, a legislator in Paris and member of the Law Commission too condemned the newly added language in a Twitter thread.
The EU parliament is set to vote on the latest MiCA draft today.
