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…

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…

Ethereum’s final four years as a proof-of-work network provide a clean historical window for a Power Efficiency Index analysis. From 2018 through September 14, 2022, Ethereum still depended on mining hardware, network compute, and measurable energy efficiency. Its 2018 physical price was approximately $82.83, giving the PEI model a clear starting point. Over the following…

Dogecoin’s 2022–2026 Power Efficiency Index (PEI) shows a large gap between DOGE’s market price and the physical progression of the Scrypt mining infrastructure that helps secure the network. Using Dogecoin’s 2022 market low of roughly $0.0528 as the physical baseline, PEI measures how network computation and mining-machine energy efficiency have changed over time. Dogecoin is…

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.…

Zcash’s resurgence is interesting because it gives us a useful Proof-of-Work comparison outside of Bitcoin. Over roughly the past four years, the Zcash network increased from about 8.2 GSol/s to 25.4 GSol/s, while leading Bitmain Equihash hardware improved from roughly 3.60 J/KSol to 3.15 J/KSol. Under the Power Efficiency Theory framework, that produces an estimated…

An electrical schematic is a symbolic representation of how components within an electrical or electronic system are connected. Rather than attempting to reproduce the physical appearance of a circuit board or machine, schematics use standardized symbols to describe components and electrical relationships. A technician can therefore examine a schematic and understand the intended current paths,…

Modern Bitcoin mining is increasingly defined by the performance of the chips themselves. Bitmain, Canaan, MicroBT, and Bitdeer compete to produce faster and more efficient SHA-256 ASICs, while emerging platforms such as Bitaxe and Proto are pushing the industry toward more accessible and open hardware development.

In a data center, some of the most important infrastructure practices are also some of the easiest to overlook. Cable bend radius is a perfect example. It simply describes how tightly a cable can be bent without risking physical damage or degrading its intended performance. Think of a cable going around a corner. Instead of…

Remote Direct Memory Access programming is a specialized method of moving data between computers with significantly less operating-system and processor involvement than conventional socket-based networking. An RDMA-capable network adapter can transfer data directly between registered memory regions, reducing repeated copying between application buffers, kernel buffers, and network-driver buffers. On Linux, applications commonly access this capability…

Control charts are a statistical process control tool used to monitor how a manufacturing, laboratory, maintenance, or business process changes over time. Measurements are plotted chronologically against a centerline and calculated upper and lower control limits, allowing technicians and quality teams to distinguish routine process variation from unusual conditions that may require investigation. A process…
