Want to work in crypto? University programs can give job seekers a leg up

There is a skills gap in the blockchain industry, and universities worldwide have created programs to help produce the next generation of blockchain professionals.

As talk of the Bitcoin halving, exchange-traded funds and other macro factors seem to point to the beginning of the next bull market cycle for crypto, many might be considering starting a career in this space. It happens to many people involved with Bitcoin (BTC), blockchain or cryptocurrencies. 

At first, they are “investors” researching and buying assets in a new digital asset class. For some, this turns into a desire to enter the decentralized ledger technology and blockchain industry. Many have decided to find paths to employment and acquire the skills necessary to jump into careers in this space.

Since the beginning of the blockchain and cryptocurrency industry, most people have found jobs through informal connections or demonstrable skills.

One-hour Bitcoin block times: What do they mean and are they frequent?

Extended Bitcoin block times have been in the headlines recently, but are they really that big of a deal — or even very common?

A Bitcoin (BTC) block that took over an hour to mine made headlines earlier in November. This is despite Bitcoin’s core protocol being written to aim to mine a block every 10 minutes.

Block 815,690 is the latest outlier to generate press speculation. This block took one hour and nine minutes to mine on Nov. 7. Public interest in an hour-plus confirmation time is not a singular event. Roughly once or twice a year, a media outlet picks up on a long block validation event and decides to run with the story.

On Oct. 17, 2022, a prominent crypto news site reported on a block that took one hour and 25 minutes to mine, which spurred a flurry of similar reports. As the story spread widely on social media, some fans reveled in the relative speed of their favored centralized altcoin.

Bitcoin is of ‘national strategic importance’ says US Space Force officer

U.S. Space Force Major Jason Lowery wants the U.S. military to prioritize the investigation of proof-of-work systems like Bitcoin for the country’s defense.

The United States needs to formally investigate using proof-of-work networks such as Bitcoin (BTC) to protect the country from cyber-inflicted warfare, according to Jason Lowery, a member of the United States Space Force.

In a four-page letter to the U.S.

“As a result, this misconception underplays the technology’s broad strategic significance for cybersecurity, and consequently, national security.”

The Defense Innovation Board is an independent advisory board set up to bring the technological innovation and best practices of Silicon Valley to the U.S.

Lowery used the letter to urge the board to advise the Secretary of Defense to investigate the “national strategic importance” of PoW systems like Bitcoin.

In his letter, Lowery explained that a proof-of-work system like Bitcoin could work to deter adversaries from cyberattacks due to the “steep costs” of a physically resource-intensive computer in the same way military assets help to deter military attacks against the country.

“Proof-of-work mirrors the physical security and deterrence strategies utilized in other domains like land, sea, air, and space,” but instead, it does it in the digital domain, Lowery explained.

Bill protecting Bitcoin mining rights passes in Arkansas Senate and House

The Arkansas Data Centers Act is now moving to the governor’s office for approval. It grants crypto miners in the state the same rights as data centers.

A bill seeking to regulate Bitcoin (BTC) mining activity in Arkansas has passed in the state’s House of Representatives and Senate. The bill will now move to the governor’s office for approval.

According to the bill, the Arkansas Data Centers Act of 2023 intends to regulate the Bitcoin mining industry in the American state, creating guidelines for miners and protecting them from discriminatory regulations and taxes.

Arkansas’ state legislators quickly passed the bill after it was proposed on March 30 by Senator Joshua Bryant. The document recognizes “that data centers create jobs, pay taxes, and provide general economic value to local communities.“

As per the approved bill, a digital asset miner is required “to pay applicable taxes and government fees in acceptable forms of currency and operate in a manner that causes no stress on an electric public utility’s generation capabilities or transmission network.“

Under the legislation, crypto miners will also have the same rights as data centers. The bill outlines that Arkansas’ government should not “impose a different requirement for a digital asset mining business than is applicable to any requirement for a data center.“

Arkansas’ move follows a similar initiative in the state of Montana. In late March, the Montana Senate passed a bill to protect crypto miners operating within the state. The bill intends to protect miners against taxes on digital assets used for payments, and to eliminate energy rates discriminating against home crypto miners and digital assets businesses.

The state of Texas went in a different direction. Its Senate Committee on Business and Commerce passed legislation on April 4 that would essentially remove incentives for miners operating under the state’s crypto-friendly regulatory environment, Cointelegraph reported.

An even more decisive move came from New York in November 2022 when Governor Kathy Hochul signed the proof-of-work mining moratorium into law, banning crypto-mining activities in the state for two years. On a federal level, crypto miners in the United States could eventually be subject to a 30% tax on electricity costs under a budget proposal introduced on March 9 by President Joe Biden aimed to “reduce mining activity.”

MIT Space Force major proposes Bitcoin mining as cybersecurity tool

An active-duty United States Space Force astronautical engineer is proposing a new cybersecurity tool to the Pentagon: Bitcoin.

An active-duty United States Space Force astronautical engineer is proposing a cybersecurity tool to the Pentagon that is capable of transforming the country’s national security and the base-layer architecture of the internet: Bitcoin (BTC).

In an academic thesis, Major Jason Lowery, who is also a national defense fellow at Massachusetts Institute of Technology (MIT), presented a new theory to the U.S. Department of Defense that Bitcoin is not just a peer-to-peer payment system but a new form of “digital-age warfare,” arguing that proof-of-work technologies will change the way humans compete globally, according to Ben Schreckinger’s review of the book in Politico.

Published in February, Lowery’s master’s degree thesis dubbed “Softwar” sits in third position on Amazon’s list of best-selling technology books at the time of writing. According to his Amazon bio, Lowery has a decade of experience serving as a weapon system developer and technical adviser for U.S. senior officials, including Bitcoin-related policies.

Lowery’s research argues that the U.S. military could use Bitcoin to stop certain types of attacks, such as denial-of-service attacks, which overload servers with too many requests. The concept involves creating software programs that only respond to signals from large transactions recorded on the Bitcoin network. This would make it harder for attackers to flood servers with fake signals and cause damage.

Lowery also suggests that the Bitcoin network is like maritime trade routes, which means it’s suited for economic exchange. Consequently, it’s crucial to protect freedom of navigation on the network, just as we protect trade routes.

By designing software programs that only respond to external signals if they come with a large enough Bitcoin transaction recorded on the network, Lowery argues they would prevent adversaries from gaining control over them.

According to the author, the U.S. should also stockpile Bitcoin, build a domestic Bitcoin mining industry and extend legal protections to the technology. In his view, Bitcoin is a self-defense weapon, and the country should protect it as it does other rights.

Post-Merge Ethereum: Grayscale extends review of ETHPoW decision

Grayscale will take 180 days at max to decide whether, when and in what manner to sell ETHPoW on behalf of the record date shareholders.

Cryptocurrency investment firm Grayscale Investments is taking more time to decide whether it should acquire and sell post-Merge forked Ethereum tokens.

Grayscale announced on March 16 that the company intends to extend the review period for evaluating the market environment to determine whether it can acquire EthereumPoW (ETHW) tokens — the forked asset that emerged after Ethereum’s Merge in September 2022.

During the review period, the firm also aims to decide whether, when and in what manner Grayscale may sell ETHW on behalf of the record date shareholders. “Such review period is not currently expected to exceed 180 days from the date hereof,” Grayscale noted in the announcement.

Grayscale reasoned the extension of the review period to the ongoing uncertainty regarding the support of ETHW tokens by digital asset custodians and trading venues. “If digital asset custodians do support the ETHPoW tokens and/or trading markets do develop, it is expected that the ETHPoW token’s value will fluctuate widely for some time,” Grayscale said, adding:

“It is not possible to predict whether Grayscale, as agent, will be able to acquire the ETHPoW tokens or the value, if any, that Grayscale, as agent, will be able to realize from sales of the ETHPoW tokens.”

Ethereum, currently the second-largest blockchain network by market value after Bitcoin, completed the Merge, a major consensus upgrade in September 2022. The upgrade moved the Ethereum network from proof-of-work (PoW) to proof-of-stake (PoS) consensus algorithm. As some people in the Ethereum community were willing to keep using the mining-based PoW Ethereum model, Ethereum has forked into two different blockchains, the main PoS-based Ethereum and EthereumPoW.

The emergence of ETHW has brought a significant challenge for crypto investment firms offering exposure to Ethereum because some investors might want to have exposure to ETHW. Some companies, such as the European exchange-traded product (ETP) issuer ETC Group, decided to launch a new ETP providing exclusive exposure to ETHW.

“The new ETP seems better because we just don’t know what will happen whether ETHW will succeed or not,” ETC Group founder Bradley Duke told Cointelegraph in September 2022.

In September, Grayscale announced that its two Ethereum-related products, the Grayscale Ethereum Trust and the Grayscale Digital Large Cap Fund, declared a distribution of rights to ETHW. Each product received the tokens as a result of a fork by late September.

Ethereum core developers set April 12 for Shanghai hard fork

The upgrade will enable staked ETH withdrawals on the Beacon Chain, completing Ethereum’s transition to a PoS consensus.

The target date for the highly anticipated Shanghai hard fork on Ethereum has now been set: April 12. Ethereum core developers approved the target deadline during the All Core Developers Execution Layer #157 call on March 16.

The Shanghai mainnet upgrade features five Ethereum Improvement Proposals, including EIP-4985, which will enable staked Ether (ETH) withdrawals on the Beacon Chain, completing Ethereum’s transition from proof-of-work to a proof-of-stake (PoS) consensus.

The target date — April 12 at 10:27:35 pm UTC, epoch 620,9536 — will now be confirmed by developers on GitHub. The fork was initially forecasted for March, but developers later pushed it back to early April.

Validators will receive rewards payments automatically at periodic intervals in withdrawal addresses. Additionally, stakers can exit positions entirely, reclaiming their full balance.

According to Etherscan, the Ethereum PoS smart contract has attracted over 17.6 million ETH, worth nearly $29.4 billion at publication time. Analysts predict that the upgrade could trigger a sell-off in the short term, as Cointelegraph reported.

The transition to PoS officially started on Sept. 15, 2022 with the Merge, a significant milestone for Ethereum that replaced miners with validators and introduced ETH staking as a key component of the network. Ethereum’s roadmap has several updates coming after Shanghai, including the “Surge,” “Verge,” “Purge” and “Splurge.” 

The switch to a PoS consensus could have regulatory implications for ETH and the crypto space. In September 2022, United States Securities and Exchange Commission Chair Gary Gensler suggested that the blockchain’s transition might have brought ETH under the regulators’ radar.

After a recent crackdown on crypto firms providing staking services in the U.S., Gensler again suggested on March 15 that proof-of-stake coins might be securities: 

“Whatever they’re promoting and putting into a protocol, and locking up their tokens in a protocol, a protocol that’s often a small group of entrepreneurs and developers are developing, I would just suggest that each of these token operators […] seek to come into compliance, and the same with the intermediaries.”

Bitcoin mining advocate is going state-to-state to educate US lawmakers

The legislatures in Mississippi and Missouri have separately introduced bills aimed at protecting certain activities of Bitcoin miners following visits from the Satoshi Action Fund.

Dennis Porter, CEO of the Satoshi Action Fund, is taking the fight for hearts and minds on Bitcoin mining to Washington, D.C., and beyond in an effort to support friendly legislation.

Porter, who first discovered Bitcoin (BTC) in 2017, told Cointelegraph his path advocating the benefits of mining has taken him to support bills in at least six U.S. states, with federal lawmakers also in his crosshairs. The Satoshi Action Fund CEO met with U.S. senators and representatives on Jan. 25 in support of proposed legislation aimed at eliminating discrimination against miners.

According to Porter, the Lummis-Gillibrand Responsible Financial Innovation Act — a bill introduced in June aimed at addressing the roles of the U.S. Commodity Futures Trading Commission and Securities and Exchange Commission on crypto regulation — has a provision addressing taxation for BTC mining rewards. He said the legislation could close a loophole allowing the Internal Revenue Service to have two bites of the apple on miners’ revenue.

“We believe that Bitcoin mining is being unfairly targeted and double taxed by the IRS currently,“ said Porter.

The conversations between Porter and members of Congress — including Senators Ron Wyden, Cynthia Lummis and Ted Budd — marked the first time the Satoshi Action Fund had stepped up in person to the national stage in defense of BTC miners. However, the organization has also stood behind bills being considered in New Hampshire, Montana, Mississippi, Missouri and Oklahoma.

Crypto mining operations in the United States have many critics among lawmakers and citizens alike, with complaints about the energy consumption of proof-of-work cryptocurrencies like Bitcoin as well as the noise pollution from crypto-mining machines. In November, New York Governor Kathy Hochul signed into law a two-year moratorium on PoW mining.

Porter added leaders in Montana have attempted to push miners out using zoning laws and considered policies including higher electricity rates. The legislatures in Mississippi and Missouri have separately introduced bills aimed at protecting certain activities of miners following visits from the Satoshi Action Fund, while Texas is home to many major blockchain firms following a crackdown in China.

“We’re just going to keep pushing hard until we get actual policy passed,” said Porter.

Rumor has it that Dogecoin could shift to proof-of-stake — What does that mean for miners?

Dogecoin shifting to proof-of-stake would be good for the environment, but what impact would it have on miners and ASIC manufacturers?

There are rumors that Dogecoin could switch from proof-of-work to proof-of-stake (PoS). 

Do I know if Dogecoin is switching to PoS?

No.

Do I think it’s going to PoS? Probably not.

But I love the “what if” game.

As a person who works in the crypto mining industry, I do my best to gauge where the market and mining industry are going, along with how that could play out. If Dogecoin makes a change to PoS or some other change to how new blocks are created, it would have massive ramifications for the mining industry.

Here’s a look at a few options and their effects.

Scrypt mining could be devastated

I’m not going to debate whether or not Dogecoin will or should switch to PoS. While it’s hard to determine if the recent rumors about the potential for a switch are true or not, they were enough to have Bitmain supposedly pause Litecoin (LTC) and Dogecoin (DOGE) miner manufacturing.

The larger question in my mind is, What happens to miners if Dogecoin switches to PoS?

First, Scrypt mining would be devastated. DOGE accounts for over 60% of the revenue with Scrypt mining. Take it away, and every L3+, every LT6 and every Mini Doge Pro — literally almost every non-L7 miner not connected to $0.04-per-kilowatt-hour electricity — would need to be unplugged immediately.

Network difficulty would likely bounce all over the place for some time, while miners with older equipment struggle with the decision to keep their ASICSs on or turn them off. The apex Scrypt miner, Bitmain’s Antminer L7, would see its profitability reduced by nearly 75%, reducing profits to a whopping $4.83/day at $0.05/kWh.

What about the miners that don’t have an industrial electric rate? At $0.10/kWh, the L7 9050M, which sold for around $9,000 a few weeks ago, would earn you $0.72/day.

Yikes!

A drastic change like this would result in those who had recently purchased an L7 being very unlikely to ever recover their investment, let alone generate any profits.

ASIC manufacturers would be forced to drop prices, further impacting their bottom line

The vastly reduced profitability would inevitably lead to the price of the L7 dropping quicker than it did during the COVID-19-induced crypto crash. Pricing miners solely by their expected ROI time, at $5 a day profit, miners would be looking at the L7 having a price tag between $1,825 (12-month ROI) and $2,737.50 (18-month ROI). This reflects a minimum price reduction of nearly 70%.

How quickly would Bitmain react? Would they gradually reduce prices week after week, similar to what Goldshell has done with many of its miners over the past few months? This strategy repeatedly left a sour taste in the mouths of customers as they watched the price of the miner they just spent thousands of dollars on being slashed over and over again.

Or would Bitmain come out and continue their recent trend of pricing miners fairly?

ASIC resellers would also bear the brunt of the negative consequences connected to a PoS shift by Dogecoin. Many L7 miners are suppliers, and retailers sitting on that would instantly need to be marked down by a substantial amount. However, based on their recent history of price-gouging customers, like charging $60,000 for a KD6 that is barely worth over $1,000 today, it’s doubtful many tears would be shed for them.

Many home miners would flood eBay and similar platforms with Scrypt miners. It would be a race to the bottom as desperate miners attempt to recoup whatever value is left in the hunk of metal that can now only be used as a doorstop or display piece if one is desperate.

Litecoin mining would survive. Those L7s would stay on because they’d still be somewhat profitable, and there really wouldn’t be another choice. It’s doubtful that the market would see a new Scrypt miner that could challenge the L7 to be developed anytime soon unless there already is a more efficient Scrypt miner in development. There are some rumors that Bitmain is working on a miner that would surpass the L7.

That’s a lot of disruption from the move to PoS, and we’ve only looked at one aspect of the crypto ecosystem. Numerous other questions and scenarios would need to be considered.

What would happen to network security?

Would the yield from staking cause DOGE to eventually be labeled a security?

Would Dogecoin be lauded for the change, or would the masses flee from what is now the second-largest PoW coin by market cap?

Now for my favorite what if. This option is unlikely, maybe even impossible, but there are different ways it could play out.

What if Dogecoin breaks away from merge-mining with LTC and creates its own mining algorithm?

Innovation and competition are healthy for every industry

What if there’s a GPU mining renaissance? After the Ethereum Merge event, there’s a ton of really cheap GPUs available on the market. Those would get expensive really quickly. Mining purists would rejoice as they build their own mining rigs while trying to figure out how much DOGE they can stack. It really would be cool to see, but it wouldn’t last. The big three manufacturers — Bitmain, Goldshell and iBelink — would scramble to be the first to market with an ASIC miner.

Eventually, they’d each have at least one ASIC miner on the market, and naturally, they’ll get more powerful and more efficient over time. The jumps and increases in difficulty would be ridiculous, and just like with Bitcoin (BTC), it would eventually no longer be profitable to mine DOGE with GPUs. But it could also open the door to something the ASIC manufacturing market desperately needs: competition.

What if, following the short-lived GPU mining renaissance, a door opens for another manufacturer or manufacturers to enter the market? Currently, Bitmain, Goldshell and iBelink are the “big three,” and it’s really Bitmain that has a total stranglehold on the market. So, while it’s likely Bitmain would come out on top, what if there’s someone out there who can be first to market and maintain that lead and establish itself as a credible and reliable ASIC manufacturer?

What if that company decided to branch out into other miners and offer them fair prices? To be fair, we do have to commend Bitmain again for the pricing on its recent rollout of industry-altering miners. Reseller markups are still an issue, but that’s another topic. Perhaps this “new” competitor would adhere to the mantra that customer service actually matters. If customers could get over the reliability concerns and the company built a good product, that could happen. Admittedly, that’s a lot of what-ifs.

Alternatively, there’s a money-grab scenario for Dogecoin. The project could go directly to Bitmain, Goldshell and iBelink and say, “We’re creating our own mining algorithm, and we’ll give it to you and you alone. How much money will you give us?”

What would Goldshell pay to bring life back to a company that has taken a series of body blows from the recent altcoin miners released by Bitmain? Or would iBelink go all out to win the rights to make the miner? IBelink just released a new BM-K3 Kadena miner that boasts 70 terahashes — a nearly 75% increase over the next closest model — and it can’t celebrate because Bitmain is about to trump that with the new KA3 that brings 166 THs. In the case of a Dogecoin offer to ASIC manufacturers, how much would Bitmain pay to maintain its market dominance?

No change could be a good thing

What if DOGE chooses to simply continue with Scrypt mining?

The status quo is not that exciting, but it seems to be the most likely outcome. Sure, there may be some changes that will pass a vote, but Dogecoin will most likely continue to be merge-mined with LTC on the Scrypt algorithm.

Bitmain is likely to continue pushing out L7 inventory before launching a more efficient Scrypt miner later this year AND Goldshell will launch a Mini Doge Pro 2 for home miners that will essentially be two Mini Doge Pros in one box. The upcoming LTC halving, along with the more efficient miners, will probably push several older models to shut down for good.

Crypto markets will go up, and crypto markets will go down. There will likely be some other crypto scandal that no one sees coming that will look incredibly obvious in hindsight. The sun will come up, and the sun will come down. Of course, most suppliers and especially resellers will continue to mark up miners and squeeze everything they can out of regular customers.

It’s impossible to know what’s going to happen with Dogecoin in the future, but crypto is one of the few industries where anything can happen on any given day.

Regardless of whether Dogecoin switches to PoS, the crypto mining landscape has always changed rapidly, and Scrypt mining is no different.

Change is coming.

Kadena CEO Stuart Popejoy on blockchain design: proof of work is a feature, not a flaw

The former JPMorgan executive shared how he learned to love crypto and why the Kadena blockchain is not letting go its firm embrace of proof of work.

When taking its blockchain public, “there was an adjustment period where we had to learn to love crypto,” Kadena founder and CEO Stuart Popejoy said. The admission sounded more like a technical adjustment than a surge of emotion on his lips, but he added, “The people who participate in your ecosystem really are your network and that is obviously not a very enterprise-y thing, that’s very grassroots.” 

The merits of private blockchains remain a matter of debate, but Kadena transitioned from a private JPMorgan blockchain in 2016 to a public spinoff in 2020, taking Popejoy, formerly a JPMorgan executive, with it.

“There was some innovation in private blockchain for a second, and that kind of represents us.” However, “there was this idea that we needed something […] that could serve business-scale needs, and that’s how we arrived at our version of a public blockchain,” Popejoy said in an interview with Cointelegraph, adding:

“This stuff is never going to take off if it can’t handle industrial loads.”

Kadena has horizontal scaling as a feature. “We focused on safe smart contracts and scalability as a safety thing, in the sense of risk management, like if you have to wait a day for your Bitcoin transaction go through,” when the system is backed up, Popejoy said.

Popejoy mentioned Bitcoin frequently. He said:

“We were very thrilled by the fundamental design of Bitcoin.”

“We believe that the real problem with proof of work is not that it uses energy, it’s that it uses energy inefficiently,” he added. “Bitcoin: there’s all this energy being used and it’s not improving the system. It’s the same slow system it was 15 years ago.”

Related: The blockchain trilemma: Can it ever be tackled?

Like Bitcoin, Kadena uses a proof-of-work consensus mechanism, “but it scales it so that we actually have horizontal scaling for proof of work,” Popejoy said. “We like to say, and it’s true, because I know how this stuff actually works, we could settle the entire U.S. stock market today, daily, on Kadena.”

Not everyone sees that speed as a benefit, but Popejoy pointed out that clawbacks can be programmed into smart contracts and security tokens.

Kadena currently has 20 chains running in parallel, but more chains would use the same amount of energy.

The real issue with proof of work is the distribution of money. “Proof of stake produces money and then it uses ownership of money to determine who runs the system,” Popejoy said. Proof of work “is the fairest distribution for getting coins into people’s hands.”
