Explain crypto mining in simple terms — what 980 EH/s of real Bitcoin computing power actually does

The Bitcoin network hash rate reached 980.91 EH/s as of October 30, 2026, performing roughly 980 quintillion guesses per second to validate transactions.

Almost Every Bitcoin Has Been Mined — and the Network Has Never Pushed Harder

Read the October 30, 2026 snapshot the right way and one number rewrites the others: 20,105,781.25 of Bitcoin’s hard-capped 21,000,000 BTC have already been mined. That is 95.74% of the supply, with fewer than 895,000 BTC left to produce. Against that near-finished issuance sits 980.91 exahashes per second (EH/s) of computing effort. The read is straightforward. That 980.91 EH/s has quietly stopped being mostly about creating Bitcoin and become mostly about protecting it.

What Mining Actually Does at This Scale

Strip away the jargon and mining is a guessing game run at industrial speed. Every machine races to find a number that, combined with a block of transaction data and run through a mathematical function, clears a specific target. That target is the difficulty parameter, currently 1.484 × 10¹⁴, and the higher it climbs the harder the puzzle gets. At 980.91 EH/s, the network is firing off roughly 980,910,000,000,000,000,000 guesses every second for the right to write the next page of Bitcoin’s ledger.

Winning pays twice: the miner takes any newly issued BTC in the block, plus the transaction fees on every payment inside it. The network settled 468,888 transactions across the 24 hours ending October 30. Blocks arrived every 10.24 minutes, fractionally above the 10-minute design target, so roughly 140 blocks landed that day, averaging about 3,350 transactions each. None of those payments became final until a miner spent real energy to include it.

That 1.484 × 10¹⁴ difficulty figure is what holds the 10-minute rhythm. Bitcoin re-tunes difficulty roughly every two weeks: faster miners and quick blocks push it up, offline machines and slow blocks pull it down. The 10.24-minute average on October 30 is the system running close to tempo even with this much hash rate thrown at it.

Why It Matters

Security scales with hash rate, and at 980.91 EH/s rewriting Bitcoin’s history would mean out-computing the entire combined network. The difficulty parameter of 1.484 × 10¹⁴ puts a hard number on that barrier. Behind it sits a network whose market capitalization reached $1.55 trillion on October 30, with BITCOIN trading at $77333.00 after a -4.54% move over the prior 24 hours. The 468,888 transactions settled that day cleared under exactly that protection.

The supply arc, meanwhile, is almost over. With 95.74% of all BTC already circulating, the block reward that first drew miners in is a shrinking slice of what they earn, which pushes transaction fees toward the center of the long-term security model. The block time tells a quieter story of self-correction: nearly 981 EH/s of effort, yet blocks running only 0.24 minutes behind schedule. That is the difficulty adjustment doing precisely its job.

Put plainly, close to a billion billion computations per second are running nonstop, not to mint more Bitcoin, since most of it already exists, but to make altering a single transaction among the hundreds of thousands settled each day mathematically prohibitive. As issuance fades, the 468,888 daily transactions and the fees riding on them are the numbers to watch next.
