Washington D.C. – August 3, 2026 – In a move that has sent ripples through the crypto derivatives market, the U.S. Securities and Exchange Commission has formally paused its approval of Nasdaq’s proposal to list cash-settled Bitcoin index options under the ticker QBTC. The decision, announced late last week, effectively freezes what would have been a…

Power Efficiency Theory provides a framework for measuring the value progression of proof-of-work systems using observable changes in computational performance and energy efficiency. The Power Efficiency Index, or PEI, organizes that framework around several distinct price points: physical price, relative price and actual price. Physical price establishes the observed reference point, while relative price represents…

Proof of work is a consensus system in which computers compete to perform verifiable computational work in order to secure a blockchain, validate transactions, and produce new blocks. In practical terms, that work is expressed through the network’s rate of compute—such as hashes per second—and the amount of energy required to produce that computation. A…

Bitcoin valuation models often begin with the same problem and arrive at very different answers. PlanB, known online as @100trillionUSD, introduced the Bitcoin Stock-to-Flow model in 2019 as a way to quantify scarcity and relate Bitcoin’s programmed supply schedule to market value. The Power Efficiency Index, developed by BitcoinVersus.tech, approaches valuation from the physical side…

The Power Efficiency Index (PEI) is a mathematical valuation model within Power Efficiency Theory that compares changes in computational performance and energy efficiency with the market price of a proof-of-work asset. Developed by bitcoinversus.tech, PEI measures the growth in a network’s rate of compute alongside improvements in the energy required per unit of computation. In…

Kaspa is trading near $0.0296 while a four year Power Efficiency Index analysis from BitcoinVersus.tech places its 2026 implied physical price near $0.1175. The gap puts the PEI reading at roughly 3.97 times the current market price, representing a divergence of about 297%. KAS also remains far below its August 2024 record of $0.2074, while…

Physical price is the lowest observed market price of a proof-of-work digital asset during a defined measurement period, typically a calendar year, and is used in Power Efficiency Index (PEI) analysis as the market’s closest observable expression of a network’s underlying digital-physical value at that time. Rather than representing the total replacement cost of mining…

Using DASH’s 2022 physical price of $32.11 as the starting anchor produces a very different valuation trajectory from the one visible in today’s market. DASH’s X11 network was operating around 5.24 PH/s in January 2022, compared with roughly 2.69 PH/s today, representing an approximately 49% contraction in rate of compute. Meanwhile, DASH’s yearly physical prices…

Bitcoin Cash provides an interesting test for the Power Efficiency Index because BCH uses the same SHA-256 proof-of-work algorithm as Bitcoin. That means Bitcoin Cash participates in essentially the same ASIC hardware ecosystem, allowing changes in the rate of compute and the rate of energy efficiency to be compared against changes in BCH’s physical price.…

The Power Efficiency Index (PEI) is designed specifically for proof-of-work cryptocurrencies because proof of work produces a measurable physical relationship between computation and energy. Bitcoin, Litecoin, Zcash and other mineable networks require machines to perform continuous cryptographic work. That gives PEI two physical variables it can track over time: network computational power and the energy…

Zcash has experienced a sharp separation between its Power Efficiency Index (PEI) and its actual market price in 2026. Using Zcash’s 2022 physical low of $33.83 as the baseline, the PEI applies the network’s compounded power-efficiency progression to estimate how its “digital-physical” value has changed over time. From 2022 through 2026, Zcash recorded approximately 3.52×…

Power Efficiency Theory (PET) argues that the value of a physical or computational system should be influenced by two things improving at the same time: its performance increases and its energy cost per unit of output declines. In proof-of-work networks, this can be measured through factors such as network hashrate, mining-machine output, and ASIC efficiency.…
