Mining

The miner's self-mining hashrate rose to 79.9 EH/s and production was up about 249 percent from a year earlier, but its bitcoin balance ended the month at 61 coins, against 257 a month earlier and 1,934 a year ago. The company's own footnote says the figure counts coins pledged as collateral, which rules out one explanation for the drop.

The Ways and Means Committee marked up H.R. 10357 on Wednesday morning, a day after the CLARITY Act stalled in the Senate. The bill waives tax on network fees of $10 or less from 2028, but settles only that staking and mining rewards are ordinary income, not when they are taxed.

Nearly 2.4 million ZEC took part, about two-thirds of the eligible supply, and 98.9 percent chose bitcoin-style halvings over a smoothed issuance curve. The result is advisory: NU7 still needs code, testing and a ZIP activation.

The BLAKE2b chain locked out every SHA-256 rig in existence when it activated on 1 September. The one venue quoting the coin showed a 131.7 per cent bid-ask spread, and no major exchange has listed it at all.

Two mining pools now decide whether four days of transaction history survive, after the project team's request for a closer recovery point was refused.

The 16-year lease at Tydal routes NVIDIA Rubin GPUs through Volta to an unnamed AI lab. JPMorgan and another top-tier bank stand behind about $1.3 billion of credit support.

The $600 million in new loans from Coinbase and Two Prime is earmarked for Long Ridge, a 505 MW Ohio site MARA wants to expand toward two gigawatts for AI hosting.

With 2.53 per cent of hashpower signalling support, the breakaway chain inherited Bitcoin's full mining difficulty and is now projected to wait 350 days before its next adjustment.

It is the thirteenth solo-mined bitcoin block of 2026, and the second one in three weeks to hit for close to a full 3.1 BTC reward.

Bitcoin difficulty dropped from 138.96T to 124.93T at block 953,568 on June 14, the second-largest negative adjustment of the year. Hashrate is down 12% in a month to 886 EH/s, and the marginal kilowatt is increasingly being sold to AI hyperscalers instead.

The May 1 difficulty adjustment dropped to 132.47 trillion after sustained hashrate fell below the symbolic one-zettahash threshold for the first time since February. The dip says more about how public miners are reallocating capex than about network security.

A vulnerability in Litecoin's MimbleWimble Extension Block allowed attackers to forge invalid peg-out transactions and attempt double-spends, triggering the deepest chain reorganisation in the network's history. GitHub commits show developers had a fix weeks before the exploit landed.

CoinShares' Q1 report shows 15 to 20 per cent of the global mining fleet now operating below breakeven, with three consecutive difficulty reductions marking the first sustained capitulation since July 2022.

The Digital Currency Group subsidiary's new pool already controls 30 per cent of Zcash's hashrate, alongside a new block explorer at Zcashinfo.com aimed at institutional miners.

CoinShares' Q1 2026 mining report reveals that production costs have surged to $80,000 per bitcoin while hash prices hit five-year lows, accelerating a historic pivot toward AI infrastructure that could see listed miners derive the majority of revenue from artificial intelligence by year-end.

Marathon Digital achieved approximately 30 exahashes per second of energized hashrate in mid-2024, representing over 30,000 operational mining devices and confirming the company's status as a leading North American mining operator.

Marathon Digital Holdings reported hash rate exceeding 30 EH/s at the end of May 2024, becoming the first publicly traded Bitcoin miner to achieve the milestone.

Bitcoin miners experienced a 50% revenue collapse following the April 2024 halving, with daily block reward revenue plummeting from $72 million to $30 million.

Bitcoin mining difficulty surged to an all-time high of 26.64 trillion on January 21, 2022, as Chinese miners who relocated following China's ban resumed operations across North America and other regions.

Kazakhstan emerged as the world's second-largest bitcoin mining hub by summer 2021 after Chinese miners relocated operations following China's comprehensive ban, taking advantage of the country's cheap electricity and permissive regulatory environment.

Heavy rainfall in Sichuan province during late June 2019 destroyed tens of thousands of mining rigs and disrupted up to 20 percent of the global Bitcoin hashrate, prompting miners to relocate operations to Xinjiang.

Bitcoin mining had quite a year in 2014. The industry faced a serious centralization scare when Ghash.io threatened a 51% attack on the network at the start of 2014. Near the year's end, mining diffic
