Jack Dorsey says that his payments company, Block (formerly Square), is expanding its bitcoin mining ambitions from designing chips to developing a full bitcoin mining system. "Building on these insights and pursuant to our goal of supporting mining decentralization, we plan to offer both a standalone mining chip as well as a full mining system of our own design." "Mining isn't accessible to everyone," Dorsey wrote when Block first entered the business of building mining hardware in 2021. "Bitcoin mining should be as easy as plugging a rig into a power source. The company was light on the details in this latest announcement, but Dorsey posted in 2021 that the company was considering a "bitcoin mining system based on custom silicon."

Magic Eden coders gathered in an Airbnb in San Jose, California, to hack in preparation for the so-called bitcoin halving. Their goal was to spend a week hacking to prepare for the so-called bitcoin halving — an event that is baked into the chain's code and helps to stave off inflation through programmatic monetary policy. watch nowTechnically speaking, runes just enables asset issuance of fungible tokens on bitcoin's base chain. The reason this is significant to developers is because of its efficiency relative to existing BRC-20 tokens, bitcoin's widely-used fungible token standard that has already received a ton of traction. "There's definitely been an awakening of capital interest in the bitcoin layer two space," said Muneeb Ali, who co-founded Stacks — an open-source blockchain network that brings smart contracts to bitcoin.

Bitcoin miners brace for impact as halving goes live
  + stars: | 2024-04-21 | by ( Mackenzie Sigalos | ) www.cnbc.com   time to read: +17 min
The technical event is relatively simple: Bitcoin miners get paid in bitcoin to validate transactions, and after 210,000 blocks of transactions are computed and added to the main chain, the reward given to the miners securing bitcoin is 'halved.' The aggregate market cap of the 14 U.S.-listed bitcoin miners tracked by JPMorgan analysts declined 28% over the first half of April to $14.2 billion, reaching year-to-date lows. Some have billed the 2024 bitcoin halving as a seminal moment for the mining sector. Marathon, along with other mining firms, has begun diversifying its business model into ancillary operations beyond purely bitcoin mining. Sullivan continued, "Bitcoin mining sites can only be repurposed if they meet the attributes that are required for HPC.

"That doesn't happen without the bitcoin miners and us being globally distributed." MacKenzie SigalosWherever the operation, bitcoin mining is a volatile business, because so much of the economics depends on the price of the cryptocurrency. Before getting into bitcoin mining, he and his two co-founders, Philip Walton and Janet Maingi, spent years building internet connectivity infrastructure in rural and urban Africa. Demand from bitcoin miners on these semi-stranded assets is making renewables in Africa economically viable.

Share Share Article via Facebook Share Article via Twitter Share Article via LinkedIn Share Article via EmailThe Bitcoin halving is set to shake up the crypto's price and the network's minersThe Bitcoin halving takes place roughly every four years, and the technical event cuts the reward pays out to miners for validating blocks of transactions. This creates a scarcity effect that could drive up the price of the cryptocurrency, while cutting miners' revenue, meaning more efficient miners perform better post-halving. Watch the video above to learn more about what the halving means for both crypto markets, and for the bitcoin miners validating transactions on the network.

NEW YORK, US - JANUARY 03: Sam Bankman-Fried leaves the court in New York, on January 03, 2023. The victim, who wrote that 30 years worth of savings had been deposited into FTX three months before the exchange collapsed, is part of a last-minute push by prosecutors to sway Judge Kaplan ahead of the sentencing. For months, Judge Kaplan has been weighing the appropriate punishment for Bankman-Fried's crimes related to the implosion of his $32 billion crypto empire. Damaging testimonyBankman-Fried was convicted of wire fraud and conspiracy to commit wire fraud against FTX customers and against lenders to sister hedge fund Alameda Research, as well as conspiracy to commit securities fraud and conspiracy to commit commodities fraud against FTX investors, and conspiracy to commit money laundering. The defense team has argued that Bankman-Fried's sentence should reflect the potential that FTX customers will be paid back in part or in full.

Bankman-Fried's fate will be announced in Manhattan on Thursday morning by Judge Lewis Kaplan, who presided over the monthlong trial in November. Bankman-Fried was found guilty of seven charges tied to the collapse of crypto exchange FTX and the roughly $10 billion of customer deposits that went missing. Lawyers representing the bankruptcy estate of FTX told a judge in Delaware last month that they expect to fully repay customers and creditors with legitimate claims. Bankman-Fried's defense team has asked the court for a sentence in the range of 63 to 78 months. Beyond the fact that he's a "first time, nonviolent offender," attorneys for the FTX founder largely lean on the argument that Bankman-Fried's risky bets paid off and the bankruptcy estate expects to fully repay FTX customers.

Bankman-Fried, the founder and former CEO of failed crypto exchange FTX, will head on Thursday to a federal court in downtown Manhattan, where U.S. District Judge Lewis Kaplan will deliver his sentencing. After a month of personally dabbling in the market, Bankman-Fried launched Alameda Research, named after the California county that housed his first office. The so-called crypto winter of 2022 wiped out hedge funds and lenders across the crypto universe. May of 2022 brought the crash of stablecoin Luna, creating a domino effect that sent crypto prices plunging, devastating other lenders. On Nov. 2, 2022, crypto trade site CoinDesk publicized details of Alameda's balance sheet, which showed $14.6 billion in assets.

Ferguson's letter is part of an eleventh hour push by the defense to appeal to Kaplan's sense of leniency as the judge gears up for Bankman-Fried's sentencing hearing on Thursday. Bankman-Fried's psychiatrist, George Lerner, told Judge Lewis Kaplan in a letter in August that the former FTX CEO has a history of depression and attention-deficit/hyperactivity disorder. Without his medication, Lerner warned the judge, "Bankman-Fried will experience a return of his depression and ADHD symptoms and will be severely negatively impacted in his ability to assist in his own defense."

The Securities and Exchange Commission scored a major win in its lawsuit against Coinbase on Wednesday, as a judge ruled that its claim that the cryptocurrency exchange engaged in unregistered sales of securities could be heard by a jury at trial. Coinbase shares fell around 2% on news of the ruling in Manhattan federal court rejecting its bid to dismiss the SEC's complaint. The regulator first filed suit against Coinbase in June, alleging the company was acting as an unregistered broker and exchange. "The Court finds that the SEC adequately alleges that Coinbase, through its Staking Program, engaged in the unregistered offer and sale of securities," Failla wrote. In June, SEC Chair Gary Gensler said that trading platforms like Coinbase "call themselves exchanges" but were "commingling a number of functions."

For two Texas-based bitcoin miners, the oil deposit offers a dream resource: wasted energy. Brent Whitehead and Matt Lohstroh, both graduates of Texas A&M University, have been mining bitcoin on the oil fields of East Texas since 2019. That's when they founded Giga Energy with the goal of taking flared natural gas and turning it into electricity to run bitcoin mines, which are notoriously power-thirsty. Whitehead comes from a long line of "wildcats," a term used to describe those who engage in high-risk exploratory drilling. On the small pilot site in Argentina, Exa Tech is handling operations on the ground, Phoenix Global is providing the gas and Giga is supplying the equipment.

Bankrupt crypto exchange FTX has struck a deal with a consortium of buyers to sell the majority of its stake in artificial intelligence startup Anthropic for $884 million, according to a filing submitted late Friday to a Delaware court. That group is purchasing nearly $500 million worth of Anthropic shares. Multiple sovereign wealth funds were reportedly clamoring for a piece of FTX's Anthropic stake. Jane Street's head of quantitative research, Craig Falls, has also proposed to personally buy around $20 million worth of shares. Should it be approved, the sale would collectively account for nearly two-thirds of FTX's shares in Anthropic.
