Cambridge estimated that Ethereum consumes 7.87 GWh annually and has the second-lowest market-value-adjusted energy intensity among the PoS networks studied. A new Cambridge study placed Ethereum near the lower end of energy intensity among major proof-of-stake (PoS) blockchains, although the network still used more electricity overall than most of the PoS networks studied. The Cambridge Centre for Alternative Finance estimated that Ethereum consumes about 7.87 gigawatt-hours (GWh) of electricity annually. When adjusted for market value, the network used roughly 33 kilowatt-hours (kWh) per $1 million, the second-lowest figure among the proof-of-stake networks assessed, behind BNB Chain. Solana used the most electricity among the PoS networks studied, at about 13.48 GWh per year. Its energy intensity was roughly 283 kWh per $1 million of market value, around 8.5 times Ethereum’s, while the networks in the comparison consumed about 38 GWh combined. Read more
The ongoing debate comes despite a broad downturn in Ordinals transaction activity over the last two years. Strategy executive chairman Michael Saylor and Blockstream CEO Adam Back have doubled down on their opposition to BIP-110, a proposed temporary fork to limit non-monetary transactions on the Bitcoin network. Bitcoin Improvement Proposal-110 was introduced in December 2025 to stop nonfungible token-like Ordinals inscriptions and other arbitrary data from “spamming” the network and to preserve Bitcoin’s main use as a peer-to-peer cash system. While critical of Ordinals activity, Saylor and Back fear a fork could do more harm than good to the network’s credibility. “There are 110 things more dangerous to Bitcoin than spam,” Saylor said in a post to X on Saturday, adding that BIP-110 could invalidate ordinary transactions on the network.

The sales come months after a major Empery shareholder demanded the firm ditch its Bitcoin treasury strategy and force the resignation of its CEO and board. Shares in Bitcoin treasury company Empery Digital rose on Friday after the firm disclosed it had sold nearly half its Bitcoin holdings to fund an AI data center project and pay down debt. Empery Digital (EMPD) shares popped 4.2% to $3.95 within the first 35 minutes of trading on Friday after the company revealed that it sold 1,400 Bitcoin (BTC) at an average of $62,200 a coin for roughly $87.1 million over the past two months. Empery, which previously operated as an electric powersports vehicle manufacturer, said some of the proceeds funded its 25% stake in a Hunt Properties-affiliated venture, which is acquiring an industrial site to be converted into an AI data center. Another $10 million was also used to pay off outstanding debt. Read more
