“If you bribe 51 percent of the miners, they will change the ledger for you. [This] tells you just how little irreversibility there is in PoW coins,” tweeted Cornell University professor and researcher in blockchain consensus protocols Emin Gün Sirer.A 51% attack on the blockchain network is not a new attack vector for PoW blockchains. However, as highlighted by Gün Sirer, it’s also not really an attack vector. On very special instances, the majority of self-interested miners on PoW blockchains have voluntarily agreed to alter a transaction history to undo critical situations.While the situation isn’t entirely the same, in the past, blockchain networks have seen their histories altered in the wake of critical moments. This happened on the ethereum blockchain back in 2016 when over $60 million worth of coins were siphoned off from the now-defunct smart contract The DAO. It also happened on the vericoin blockchain back in 2014 after $8 million worth of coins were hacked.While controversial, both decisions were supported by the primary developer community who launched system-wide upgrades or hard forks to enable otherwise infeasible amendments to the blockchain transaction history.Yet those choices weren’t without their repercussions; the resulting ethereum fork resulted in two distinct chains, ethereum and ethereum classic, respectively.A resounding noStill, many in the bitcoin community took to social media to deride the idea as both infeasible as well against the philosophical underpinnings of the technology.In Binance’s particular case, prominent members of the bitcoin community point out that bitcoin being the world’s largest blockchain is a particularly unique case with a reputation to uphold.“Talk of forking or reorganizing the blockchain is close to heresy,” tweeted billionaire bitcoin investor Michael Novogratz. “When the ethereum community did it the project was like 5 months old. A baby. Bitcoin now has $100bn market cap and is a legitimate store of wealth.”It would also be unfair according to Adam Back – CEO of bitcoin development startup Blockstream – given that the latest Binance hack is nowhere near as severe as previous hacks suffered on the bitcoin blockchain.“A Bitcoin reorg is just not happening, and I doubt any Bitcoin industry, miners nor developers considered it either. Recall 2014 $473mil, 2016 bitfinex hack $72mil, 2019 binance $40mil etc. #NotHappening,” tweeted Back.
Many central banks reduced policy interest rates to zero during the global financial crisis to boost growth. Ten years later, interest rates remain low in most countries. While the global economy has been recovering, future downturns are inevitable. Severe recessions have historically required 3–6 percentage points cut in policy rates. If another crisis happens, few countries would have that kind of room for monetary policy to respond.To get around this problem, a recent IMF staff study shows how central banks can set up a system that would make deeply negative interest rates a feasible option.
All of this is a sign of a micro-economy in trouble, as Muhammad Salman Anjum, an investor who eats dinner alone by himself in the buffet hall each night, explains. He has a pragmatic take on all these beautiful young women having blockchain exhaustively explained to them by schlubby-looking guys who can’t believe their luck. ”One of the elements in blockchain is about fundraising the ICOs. So you can guess why they are here—to pamper the investors. Because it’s tough now.”In 2017, Salman says, it was relatively easy to raise funds for a nine-figure ICO. Now that crypto prices have crashed, demand on “the supply side of the ICOs is booming, and the demand for the investors is shrinking.” Since the actual mood at this moment is conservative-going-on-terrified, these glamorous models seem to have been hired to give the ship—and the passengers’ selfies—the glitzy appearance of the boom times of 2017.One of the ways men bond is by demonstrating collective power over women. This is why business deals are still done in strip clubs, even in Silicon Valley, and why tech conferences are famous for their “booth babes.” It creates an atmosphere of complicity and privilege. It makes rich men partners in crime. This is useful if you plan to get ethically imaginative with your investments. Hence the half-naked models, who are all working a lot harder than any of the guys in shirtsleeves.The cruise’s panelists all tout decentralization’s promises of shared responsibility, community, and freedom, but the version I see here means that nobody knows precisely who is responsible for all of this. It’s nobody’s specific fault that we’re trapped on a floating live-action walkthrough of how un-trammelled free-market capitalism can be bad for women, given that money and power are things women tend to have less of.
A new study that was undertaken by Queen Mary University of London and the University of Cambridge, UK, came to some interesting conclusions about how blockchain could fit into the EU’s complex regulatory structure.
In a time of vulnerability, crypto investors are moving to Puerto Rico, attracted by lucrative tax incentives. They plan to regenerate the island using blockchain technology. But not all of the locals support their bold plans
A report has claimed that GDPR could hinder innovation in blockchain within Europe. If that is right, then this could be enough to ensure that the technology stars of tomorrow, the next Amazons or Googles, won’t be European. The report did hint at the opportunity, however. Blockchain could be as transformative for business as the internet, at least nine out of ten technology professionals think that, or so found a survey by BTL Group.
Blockchain exists for ~10 years and still there are no mainstream use cases where it replaced the incumbent tech, other than illegal activity. There is a fundamental reason for that.BCh offers a single unique feature: distributed trusted transaction (DTT). DTT competes with a centralized transaction == transaction with a trusted third party (T3P). DTT is by definition distributed and as such is *always* more expensive than a T3P all other things being equal: reaching consensus with multiple parties is harder than with a single party. In order for DTT to be competitive with the old tech T3P, the distributed nature of DTT must offer some advantage for people to be willing to pay the required premium. So far the only use case where people or willing to pay this premium is circumvention of regulation, when the trusted third party does not exist. This brings us to this list of use cases:1. Circumvention of regulation.This is the only meaningful use of DTT.China has capital flow controls which effectively bar companies and individuals from moving money out of China. To get around these regulations people buy video cards and electricity in China for CNY, mine cryptocoins, sell them in the States for USD. That’s the largest market right now, much bigger than buying drugs on the likes of Silk Road. This use case also includes ICOs and other pump and dump schemes.2.

Pierce, meanwhile, was about to try to repeat his success in e-sports when people began mentioning cryptocurrency to him roughly a year after the first Bitcoins were mined. Pierce was shocked that he’d never heard of it. “There were no storytellers who knew how to convey the information in simple insights, so it required a lot of real heavy lifting to figure out,” he says. “I didn’t have the time to appreciate the power of decentralization at first. The day I got it, I knew that was it.”Bannon recently took a leap into cryptocurrency as well, not just because of its financial implications, but because of its political ones. “This whole populist revolt is going to come down to this concept of currency,” he says. “You can see the forces that are aligned to take advantage of it. Every smart person that I admire in the world, and those I semi-fear, is focused on this concept of crypto for a reason. They understand that this is the driving force of the fourth industrial revolution: steam engine, electricity, then the microchip – blockchain and crypto is the fourth. There’s going to be a war for control for this.”Once Pierce caught on to the potential of this new digital cash, he became an evangelist, giving away Bitcoins to everyone he could, whether to an influencer or to the audience at one of his talks. He eventually stopped giving the money away because “no one appreciated it, then they lost it, and it was a waste of my fucking time. I get messages all the time from people saying, ‘I think of how much I lost because I didn’t take it seriously.’ ”
Ironically, Bitcoin’s success depends on the same critical factor as a state-issued “fiat” currency: the collective trust of its community of users. Their confidence in the accuracy of the ledger of all Bitcoin transactions is what makes the currency viable. Law-abiding citizens want efficient, reliable payments. Bitcoin’s mysterious creator, Satoshi Nakamoto, realized this. His 2008 white paper said a great deal about cutting out banks; it said nothing about evading the rule of law.
I am proposing that the second point on Bitcoin’s risk spectrum should be LNRR, the Lightning Network Reference Rate. Routing fees earned on bitcoin staked to Lightning payment channels can be expressed as an interest rate. The rates received on the payment channel or node level can be hashed and cryptographically provable. Node operators can opt-in to publish realized interest rates on their capital. If a consensus can be reached on an interest rate calculation protocol, capital providers can publish interest rates in an open and transparent way. Positive interest rates will attract bank-like entities that believe they can earn positive return using effective payment channel management and security techniques. Some bitcoin previously held in cold storage will seek the income attainable in Lightning Network, the first ever example of an opportunity cost tradeoff in bitcoin that doesn’t require additional counterparty risk. Bitcoin staked to Lightning is the most unique income producing asset in all of monetary history: income with zero counterparty risk. The historical implications of this on capital markets are tremendous.
