PoW Oracle & Suffering Index
BackPoW is a real-time Proof of Work oracle. It tracks the Suffering Index (coins mined at a loss), Cost of Production (CoP) versus spot price, mining-versus-spot arbitrage, and solo mining block-chance calculators for 130+ PoW cryptocurrencies — the cold, honest numbers behind proof-of-work mining.
Live Proof of Work Suffering Index — coins mined at a loss
35 Proof of Work coins are currently unprofitable to mine: their electricity cost of production is higher than the coin's spot price. Ranked by how far underwater they are, updated daily.

Cost of Production vs spot price
BackPoW computes each coin's Cost of Production from live network difficulty and the most efficient mining hardware, then compares it to the market price. A coin trading below its CoP is cheaper to buy than to mine; a coin trading above it can be profitably mined.

Frequently asked questions
What is the BackPoW Suffering Index?
The Suffering Index ranks Proof of Work coins currently mined at a loss — where the electricity cost of production exceeds the coin's spot price — so you can see live which coins are unprofitable to mine right now. BackPoW recalculates it daily across 130+ PoW coins.
What is Cost of Production (CoP) in crypto mining?
Cost of Production is the electricity cost to mine one coin on the most efficient hardware. When CoP is above the market price the coin is 'underwater' and miners lose money; when it is below, mining is profitable. Comparing CoP to spot price also reveals mine-vs-buy arbitrage.
What is a solo mining calculator?
It estimates how long it takes to find a block on your own and your probability of success over time, from your hashrate and the coin's live network difficulty, using the exponential/Poisson model of memoryless proof-of-work hashing.
