    Please describe the feature you’d like to see added.

    Hello,

    I would like to open a feature request or initiate a discussion around the possibility of reducing the overall energy consumption of the Bitcoin network.

    While Bitcoin has proven its resilience and decentralization through proof-of-work (PoW), the current energy requirements to secure the network are significant. This has raised growing concerns regarding its environmental impact, especially in the context of global efforts to reduce carbon emissions.

    Key Points:

    High Energy Demand: The Bitcoin network consumes more energy annually than some entire countries. This energy usage is mostly due to the PoW mining mechanism.

    Environmental Concerns: A large portion of mining operations still rely on fossil fuels, increasing the carbon footprint of the network.

    Public Image and Adoption: Bitcoin’s environmental footprint is often cited as a barrier to wider adoption and public acceptance, particularly among environmentally-conscious users, regulators, and institutions.

    Long-Term Sustainability: Exploring ways to make the network more energy-efficient could help ensure its viability in an increasingly carbon-regulated global economy.

    Possible Directions:

    Research on protocol-level optimizations that reduce energy intensity without compromising decentralization or security.

    Encourage community dialogue about the future of PoW and the possibility of alternative consensus models or enhancements to make mining more sustainable.

    Incentivize greener mining practices or provide protocol-level support for low-carbon energy sources.

    This is not a trivial issue, and any change to Bitcoin’s consensus mechanism must be approached with extreme care. However, opening the conversation and exploring possible paths toward reducing the network’s energy demand would be a meaningful step for Bitcoin’s future.

    Thank you for your time and consideration.

    Alexander

    General bitcoin questions and/or support requests are best directed to the Bitcoin StackExchange or the #bitcoin IRC channel on the Libera Chat network.

    For proposed protocol changes you can post to the bitcoindev mailing list or the Delving Bitcoin Discorse forum.

    For general bitcoin discussion you can try bitcointalk or https://reddit.com/r/bitcoin.

    That would be good because it is an argument that in my opinion hinders the mass adoption of bitcoin as a global currency.
