Ethereum hash rate dropped in half

One of the most pivotal events on Bitcoin's blockchain is halving. It induces inflation in the cryptocurrency's price by reducing the number of bitcoin in circulation and increasing demand for Bitcoin. Bitcoin halving has implications for all stakeholders within Bitcoin's ecosystem. To explain what a Bitcoin halving is, we must first understand a bit about how the Bitcoin network operates. Bitcoin's underlying technology, blockchain, basically consists of a collection of computers or nodes that run Bitcoin's software and contain a partial or complete history of transactions occurring on its network.

Illustration: Blood Bros. Bitcoin soaks up most of the hype and the opprobrium heaped on cryptocurrencies, leaving its younger and smaller sibling Ethereum in the shadows. But Ethereum is anything but small.

Ethereum mining consumes a quarter to half of what Bitcoin mining does, but that still means that for most of it was using roughly as much electricity as Iceland.

Indeed, the typical Ethereum transaction gobbles more power than an average U. Like Bitcoin, Ethereum relies on a blockchain , which is a digital ledger of transactions maintained by a community of users. However, Buterin designed Ethereum to do more than securely maintain a ledger without a central authority. What gives the Ethereum blockchain such potential is its ability to store data, support decisions, and automate the distribution of value. Smart contracts have obvious business applications, but the long-term hope is that apps built from them will eventually make Ethereum the ultimate cloud- computing platform.

While there are some multimillion-dollar apps running on it, even Buterin says he suspects that Ethereum is consuming more resources than it returns in societal benefits. The problem is all that mining. Like most cryptocurrencies, Ethereum relies on a computational competition called proof of work PoW. So the more computational firepower you have, the better your chances to profit.

PoW mining is difficult by design. The idea is to prevent any one entity from controlling the blockchain. Bitcoin users would have little recourse because miners are anonymous. In theory, PoW keeps mining a distributed affair.

In practice, however, the development of application-specific ICs ASICs that accelerate mining, produced by a handful of chip fabs in China, has concentrated power over many cryptocurrencies.

This ether-mining algorithm penalizes the use of ASICs. The resultant energy demand has created a backlash from environmentalists. Utilities and communities, meanwhile, see financial risk and opportunity costs if they cater to cryptocurrency miners that gobble up cheap electricity while creating few jobs.

Serving miners may require utilities to make equipment upgrades, which could become superfluous if cryptocurrency prices crash and mining operations shut down. Such pushback from utilities and their regulators may further erode the security of PoW-based cryptocurrencies.

Restricted access to power and rising energy costs will hinder new miners from joining the game, accelerating the concentration of mining power. As it concentrates, the risk of collusion and fraud increases. For me it is the No. Instead of millions of processors simultaneously processing the same transactions, PoS randomly picks one to do the job.

In PoS, the participants are called validators instead of miners, and the key is keeping them honest. A bigger stake earns a validator proportionately more chances at a turn, but it also means that a validator caught cheating has lots to lose.

The blockchain transactions themselves are not super computationally intensive. Slashing computational power and energy use is not just an ecological move. Moving to PoS could also boost security. By , the advantages of PoS had already convinced the Ethereum community to make the shift, and leaders such as Buterin had expected to do so in just a year or two. This time bomb has, however, functioned more like an alarm clock with a snooze button. And they will likely hit snooze again shortly. But the process of turning those theoretical solutions into efficient software has been moving slower than expected.

Before then, they had anticipated building PoS into the existing Ethereum blockchain. In June, they decided to make a clean break and to build an entirely new blockchain—one that operates solely via PoS. The two-chain solution—dubbed Ethereum 2. Hauner, who is leading an effort called Lighthouse to build an Ethereum 2. Just a few months after the decision to shift to Ethereum 2. Buterin says public testnets could be handling another Ethereum 2.

As a multibillion-dollar network, Ethereum obviously has a lot to lose if it launches glitchy or insecure technology. But Ethereum also has a lot to lose if it delays much longer. Like Ethereum, they seek to prove that high security and high efficiency are not at odds. The first to unleash the potential for blockchain applications may well become the computing platform of the future. The others will probably wither away. Charles Q. Quantum computers are theoretically far more powerful than classical computers on important tasks such as investigating novel battery designs or discovering new drugs, but they are currently too error prone for practical use.

Now Amazon , Google , IBM , and others are pursuing a bevy of innovative strategies to develop fault-tolerant quantum computers based on superconducting circuits. Whereas classical computers switch transistors either on or off to symbolize data as ones or zeroes, quantum computers use quantum bits , or "qubits," which because of the surreal nature of quantum physics can exist in a state of superposition where they are both 1 and 0 at the same time.

This essentially lets each qubit perform two calculations at once. The more qubits that are quantum-mechanically linked, or entangled, the more calculations they can perform simultaneously. Present-day state-of-the-art quantum computers typically suffer roughly one error every 1, operations.

Many practical applications demand error rates lower by a billionfold or more, says Oskar Painter , head of Amazon Web Services ' AWS quantum-hardware program and an experimental physicist at the California Institute of Technology. In addition to building qubits that are physically less prone to mistakes, scientists often hope to compensate for high error rates by spreading quantum information across many redundant qubits. This would help quantum computers detect and correct errors, so that a cluster of a thousand or so "physical qubits," the kinds that researchers have developed to date, can make up one useful "logical qubit.

One strategy Amazon is exploring to build a fault-tolerant quantum computer involves machines that are inherently stable against error. Scientists can theoretically encode data in a qubit using virtually any pair of states of a quantum system—for instance, two of a molecule's potentially many different energy levels.

Specifically, Amazon's design relies on an oscillator whose fluctuations move in phase. Its cat states rely on pairs of fluctuations with opposite phases in the same oscillator.

Painter and his colleagues found they could make cat qubits that are highly resistant to bit flip, where a qubit flips from one state to another, one of two main sources of error a superconducting qubit can have.

A microwave package encloses the quantum processor. The packaging is designed to shield the qubits from environmental noise while enabling communication with the control system.

AWS Quantum Computing. Bit flips result from environmental noise, such as spikes of heat or electricity, so using cat qubits can help protect a quantum computer against outside disruption, he notes. This strategy does make cat qubits more vulnerable to the other common source of error a superconducting qubit can have, known as phase flip, where it switches between one of two opposite phases.

However, Amazon says it can then use quantum error-correction schemes to compensate for phase flips. Focusing on just one kind of error instead of two "reduces the overhead resources you need for quantum computing by a factor of a square root," Painter says. This can readily amount to orders of magnitude fewer physical qubits needed. At the AWS re:Invent conference in December, Painter and his colleagues described research on cat qubits that were roughly 20, times as biased toward bit flip than phase flip.

Within the next year, they hope to reveal a logical qubit based on cat qubits, he adds. In theory, using more physical qubits can result in an exponential suppression of quantum-computing error rates. Google recently showed this was possible using its qubit Sycamore quantum computer , which in carried out a calculation in seconds that the company estimated would take Summit, the world's most powerful supercomputer at that time , 10, years.

Google had physical qubits serve either as "data qubits" that encode the logical qubit or "measure qubits" tasked with repeatedly detecting errors in their fellow qubits. When the qubits were arranged in a one-dimensional chain, with each qubit having two neighbors at most, increasing the number of qubits led to an exponential suppression of the rate of bit or phase-flip errors, reducing the amount of errors per round of detections and corrections up to more than a hundredfold when they scaled up the number of qubits from 5 to However, quantum errors are not limited to just one direction.

But when Google researchers used a " surface code ," in which they arranged the qubits in a two-dimensional checkerboard pattern, they found that such a design using data and measure qubits performed as expected from computer simulations.

In subsequent work , Google tested how a different two-dimensional qubit grid could help develop lower-error qubits. They employed 31 data qubits on Sycamore to run a " toric code "—so named because it mimics a lattice placed on the surface of a torus—to simulate exotic two-dimensional quasiparticles known as anyons.

Anyons are collective excitations not associated with any one qubit, "sort of like how a crowd can do 'the wave' and the wave isn't associated with any particular person," says Jimmy Chen , a research scientist at Google. Pairs of anyons can "braid," or swap places. Braiding means that anyons can in a sense remember how they behaved with respect to one another even after they get separated.

A "topological qubit" created from pairs of anyons could benefit from a kind of protection conveyed by its topology, defending it from disruptions and reducing error rates. Instead of arranging its qubits in square grids, IBM arrays its qubits in hexagonal lattices , with a qubit on each point and another on each flat edge. This pattern, now used in all the company's quantum computers—including its qubit Eagle quantum processor —can reduce potential errors caused by accidental interactions between neighboring qubits.

In comparison, in square grids, a qubit may have up to four neighbors. IBM believes this new layout will help it scale up faster to much larger practical quantum computers. The company aims to debut its 1,qubit Condor processor in This architecture does require new quantum error-correction codes adapted to hexagons instead of squares, which IBM is actively researching.

Recent work from IBM suggests quantum error-correction codes adapted to hexagons "can lead to a significant reduction in error rates," says Sheldon. In addition to actively correcting errors, IBM is exploring error-mitigation schemes to avoid them in the first place. One strategy, zero-noise extrapolation, confronts how quantum computers are typically very sensitive to disruptions from noise in their environment. By repeating quantum computations at varying levels of noise, the researchers can extrapolate what the quantum computer would calculate in the absence of noise.

Even if quantum computers do scale up to many thousands of physical qubits to potentially support enough logical qubits for practical applications, they will have to deal with another major challenge—the need for extra "ancilla qubits," Painter says.

When two logical qubits are connected in a quantum logic gate—an elementary operation that quantum computers use to perform a computation—scientists want to make sure that each physical qubit in a logical qubit interacts with only one physical qubit in the other logical qubit.

But while the performance restoration was partial, it can be safe to say that a full workaround to NVIDIA's crypto mining limiter on LHR cards will arrive sooner or later. No other cryptocurrencies were mentioned in the log, which could mean miners will want to buy up new stocks again given that Ethereum's value remains stable, according to Coindesk. They did deliver around half of the hashrate that non-LHR models had at a price that most miners considered bad for business. Sadly, the short answer is it's very probable. This has caused many GPU-starved PC gamers to see a glimmer of hope during the ongoing global shortage. Many factors contributed to these price drops, but perhaps it was the decreased demand from miners that caused much of the change.
