Paypal, in collaboration with Energy Web and DMG Blockchain Solutions Inc., has introduced a groundbreaking strategy to promote environmentally sustainable practices in bitcoin mining. The research-backed initiative aims to encourage miners to utilize low-carbon energy sources by offering financial incentives.
The rise of the Bitcoin network has raised concerns about the environmental impact of mining, particularly the carbon emissions from the energy-intensive proof-of-work (PoW) process. In response to this urgent issue, Paypal’s Blockchain Research Group has partnered with Energy Web and DMG to develop a system that rewards miners who use green energy. The objective is to shift the industry towards more sustainable energy sources by making green mining financially attractive.
“We propose a solution to this problem by providing incentives to miners who use low carbon energy sources,” explain the authors of the paper. “The proposal rewards miners with bitcoins in a trust-independent manner, meaning they don’t have to rely on a third party to earn the reward, when they can verifiably prove that they use a significant portion of low carbon energy sources in their mining operations.”
Miners who use verified low-carbon energy sources are identified as “green miners” and are rewarded with bitcoin (BTC). These rewards are structured through a unique crypto-economic model that involves a multi-sig payout address. Transactions are preferentially routed to green miners, who can then claim their rewards by mining these transactions. The researchers believe that this approach not only incentivizes cleaner mining practices but also increases the flow of transactions towards these environmentally friendly miners.
The green mining protocol involves several technical components, including the identification of green miners through Energy Web’s validation platform and the use of public keys associated with green energy usage. These keys help manage and distribute incentives, ensuring that only eligible miners can access the rewards. The system also involves broadcasting transactions with low fees to discourage non-green miners from processing them, further ensuring that incentives are specifically directed towards green miners.
“When a green miner receives the transaction in the mempool, they identify it as a green transaction based on the multi-sig payout address,” the paper explains. “The miner must include the transaction while assembling a block and include an additional redeem transaction within the same block to consume UTXO that locked bitcoins in the payout address.”
Paypal’s Blockchain Research Group adds:
“This additional transaction will have a recipient address belonging to the green miner. As a result, only the green miner who includes the green transaction, redeem transaction, and successfully mines the next block is assured of earning the bitcoin reward.”
By harnessing the power of blockchain technology and crypto-economic rewards, the supporters of this research paper aim to facilitate a transition to renewable energy in the mining sector. However, it is important to note that this paper from Paypal presents a hypothetical scenario that has yet to be tested in real-world conditions among industry miners.
