How Zero-Knowledge Proofs are Revolutionizing Blockchain Technology

Blockchain technology has the potential to revolutionize industries beyond finance, and it is often associated with popular cryptocurrencies like Bitcoin. It operates as a decentralized and distributed ledger, enabling secure, transparent, and immutable record-keeping. However, traditional blockchains face significant challenges related to privacy and scalability.To get more news about blockchain knowledge, you can visit wikifx.com official website.

Privacy concerns arise due to the transparent nature of blockchain transactions, while scalability issues stem from the increasing size and complexity of the blockchain. To address these challenges, Zero Knowledge Proofs (ZKPs) offer a promising solution. ZKPs allow for verifiable transactions without revealing sensitive information, and in this blog, we will delve into how ZKPs can reshape the blockchain landscape by addressing privacy and scalability concerns in traditional blockchain networks.
What are Zero Knowledge Proofs (ZKPs)?
Zero Knowledge Proofs (ZKPs) are cryptographic protocols that allow one party, known as the prover, to prove to another party, known as the verifier, that a specific statement is true without revealing any additional information about the statement. In the context of blockchain technology, ZKPs are significant as they offer solutions to the challenges of privacy and scalability.

ZK-rollups are a type of Layer 2 scaling solution that uses Zero Knowledge Proofs (ZKPs) to provide scalability and privacy benefits to blockchain transactions. ZKPs allow the prover to prove the validity of a statement without revealing any additional information, while ZK-rollups use this technology to bundle multiple transactions off-chain and verify them on-chain as a single transaction. This approach greatly reduces the computational cost and transaction fees associated with blockchain transactions while maintaining the integrity and security of the underlying blockchain network. In summary, ZK-rollups are a practical application of ZKPs that can significantly enhance the scalability and privacy of blockchain transactions.
Properties of ZKPs
• Completeness: Zero-Knowledge Proofs (ZKPs) ensure that a valid statement can be proven to be true to the verifier. The prover can provide convincing proof that the statement is true, and the verifier can verify the proof's validity.

• Soundness: ZKPs provide soundness, ensuring that an invalid statement cannot be proven to be true by the prover. If the statement is false, the prover will not be able to generate valid proof, and the verifier will not be convinced of its truth.

• Zero-Knowledge: ZKPs allow for proof without revealing any additional information about the statement or the proof itself. The prover can prove the statement's truth without disclosing any knowledge or details about how the proof was generated, ensuring privacy and security in the process.
Types of ZKPs
1. Interactive Zero-Knowledge Proofs (iZKPs) is a type of proof in which the prover and verifier engage in a back-and-forth process to prove a statement. The verifier sends random challenges to the prover, who must respond with proof that satisfies the verifier's challenges. The Schnorr protocol, the Fiat-Shamir heuristic, and the Guillou-Quisquater protocol are examples of iZKPs.

2. Non-Interactive Zero-Knowledge Proofs (NIZKPs) is another type of proof that the prover generates without interaction with the verifier. The proof is then sent to the verifier for verification. NIZKPs are more efficient and faster than iZKPs as they do not require any interaction between the prover and verifier. zk-SNARKs, Bulletproofs, and STARKs are examples of NIZKPs.

What is cryptocurrency and how does it work?

Cryptocurrency, sometimes called crypto-currency or crypto, is any form of currency that exists digitally or virtually and uses cryptography to secure transactions. Cryptocurrencies don't have a central issuing or regulating authority, instead using a decentralized system to record transactions and issue new units.To get more news about Crypto currency market, you can visit wikifx.com official website.

What is cryptocurrency?
Cryptocurrency is a digital payment system that doesn't rely on banks to verify transactions. It's a peer-to-peer system that can enable anyone anywhere to send and receive payments. Instead of being physical money carried around and exchanged in the real world, cryptocurrency payments exist purely as digital entries to an online database describing specific transactions. When you transfer cryptocurrency funds, the transactions are recorded in a public ledger. Cryptocurrency is stored in digital wallets.

Cryptocurrency received its name because it uses encryption to verify transactions. This means advanced coding is involved in storing and transmitting cryptocurrency data between wallets and to public ledgers. The aim of encryption is to provide security and safety.

The first cryptocurrency was Bitcoin, which was founded in 2009 and remains the best known today. Much of the interest in cryptocurrencies is to trade for profit, with speculators at times driving prices skyward.
How does cryptocurrency work?
Cryptocurrencies run on a distributed public ledger called blockchain, a record of all transactions updated and held by currency holders.

Units of cryptocurrency are created through a process called mining, which involves using computer power to solve complicated mathematical problems that generate coins. Users can also buy the currencies from brokers, then store and spend them using cryptographic wallets.

If you own cryptocurrency, you don't own anything tangible. What you own is a key that allows you to move a record or a unit of measure from one person to another without a trusted third party.

Although Bitcoin has been around since 2009, cryptocurrencies and applications of blockchain technology are still emerging in financial terms, and more uses are expected in the future. Transactions including bonds, stocks, and other financial assets could eventually be traded using the technology.

Cryptocurrency examples
There are thousands of cryptocurrencies. Some of the best known include:

Bitcoin:

Founded in 2009, Bitcoin was the first cryptocurrency and is still the most commonly traded. The currency was developed by Satoshi Nakamoto - widely believed to be a pseudonym for an individual or group of people whose precise identity remains unknown.

Ethereum:

Developed in 2015, Ethereum is a blockchain platform with its own cryptocurrency, called Ether (ETH) or Ethereum. It is the most popular cryptocurrency after Bitcoin.

Litecoin:

This currency is most similar to bitcoin but has moved more quickly to develop new innovations, including faster payments and processes to allow more transactions.

Ripple:

Ripple is a distributed ledger system that was founded in 2012. Ripple can be used to track different kinds of transactions, not just cryptocurrency. The company behind it has worked with various banks and financial institutions.

Non-Bitcoin cryptocurrencies are collectively known as "altcoins" to distinguish them from the original.

Best cryptocurrency exchanges and trading apps in April 2023

While cryptocurrency has surged in popularity in recent years, only a minority of Americans have actually traded it. Among the most popular cryptos are Bitcoin, Ethereum and Cardano, each of which has seen a lot of action as prices rise and fall. The appeal for traders? The potential to make significant money on the volatility of these highly speculative assets.To get more news about best crypto exchange, you can visit wikifx.com official website.

Increasingly, traders have more and more ways to access cryptocurrencies. New exchanges and trading platforms have started in response to the wide interest in crypto. In fact, you may already have an app on your phone that lets you trade. For example, if you have the PayPal or Venmo apps, you can buy and sell at least a few different cryptocurrency coins. But other apps and exchanges give you access to a wider selection of cryptocurrency - there are literally thousands - or they offer other benefits such as lower cost.
The platforms below include specialized crypto exchanges, online brokers, and cash and payment apps. We've included pricing as well as how many coins you're able to trade, so you can get a sense of the scope of each app or exchange.

If you're interested in trading the largest cryptocurrency, Bitcoin, exclusively, it may not make sense to go with an app that offers you dozens of other coins. On the other hand, if you're looking to trade whatever is hot at the moment, consider an app or exchange with more variety.

Bittrex
Bittrex is an attractive option for crypto traders thanks to its straightforward low-cost commissions, particularly for those trading high volumes. If you're trading less than $50,000 every 30 days, you'll pay between 0.25 and 0.30 percent in commissions, but the fees fall quickly from there if you're trading big bucks. Plus, Bittrex doesn't charge for USD deposits or ACH withdrawals.

Hard-core crypto enthusiasts will also appreciate Bittrex's offering of about 100 cryptocurrencies to trade. You'll find all the most popular coins including Bitcoin, Ethereum and Dogecoin, as well as the more obscure listings.
Binance.US, which is the American arm of the larger Binance organization, is one of the best crypto exchanges because of its low trading costs. Bitcoin and Ethereum traders can access commission-free trades, while other coins are priced on a sliding scale for high-volume traders. Plus, if you use Binance's in-house coin, BNB, to pay trading fees, you'll get a discount of 25 percent.

The broker eToro is all crypto, all the time (at least for American traders, though others can trade stocks). At eToro, you'll have access to about 80 cryptocurrencies, including quite a few, such as Tezos, Uniswap and Polygon, that you won't normally find on the traditional brokerage apps. The app doesn't charge a direct commission but rather a flat spread markup of 1 percent, regardless of which coin you purchase or how much.

Coinbase
Coinbase is a specialized cryptocurrency exchange that allows you to trade a bunch of digital currencies, 230 at the latest count. That range will likely scratch your crypto itch, since it includes most of the top coins, including Bitcoin, of course. But what will you pay for using the basic service? Unfortunately, Coinbase has become cagier about what you'll pay to trade, recently obscuring the fee structure on its website.

When it was visible, the fee structure was complex, to say the least. You'd pay a spread markup of about 0.5 percent and a transaction fee that depended on the size of the transaction and the funding source. For Coinbase Advanced Trade, you'll pay fees that start at 0.6 percent for 30-day volume under $10,000 and decline to as low as 0.15 percent for up to $100,000 in volume and then head even lower.
Kraken
Kraken is another specialized cryptocurrency exchange that lets you trade a ton of different coins, including the most popular as well as some (Solana, Uniswap, Cardano and more) that are not typically available on the usual financial apps. In total, the exchange supports trading in more than 212 cryptos. Kraken does not offer its service to residents of New York and Washington state.

Commissions on Kraken Pro are competitive, ranging from 0.16 to 0.26 percent at the lowest volume levels and declining to a range of 0 to 0.1 percent with volume of $10 million or more in the last 30 days. High-net-worth traders can also access margin trading, increasing their buying power (and risk). While you can deposit money via ACH for free into Kraken, debit or credit card transactions incur a 3.75 percent fee plus 25 cents, and you can get hit with a 0.5 percent online banking processing fee if you fund through a bank, at last check.

Tencent taking global Honor of Kings as China continues to block its new releases

Chinese giant Tencent is bringing its flagship title to global markets as it attempts to offset the increasing restrictions and limited growth of its home market.To get more news about honor of kings top up, you can visit topuplive.com official website.

The company announced Honor of Kings will be "rolling out... to global gamers by the end of the year" via Level Infinite, the publishing label Tencent established back in December.

There will be closed beta tests in the coming months, starting in July.

The news comes as the South China Morning Post reports that Tencent has once again been left out of the latest wave of regulator approvals for publishing licences.

The Chinese government mandates that all titles released in the market require a publishing licence, although regulators froze the approvals process for nine months -- the second time this has occurred.

A first batch of 45 games were approved for release in April, with another 60 granted a licence on Tuesday. The latter included Keqier Frontier, a new title from Genshin Impact developer MiHoYo, and Perfect World Games' Black Cat Anecdote Society.

The approval of just 105 games so far this year is a marked decline when compared to 2017, where regulators approved more than 9,000 games for release in China over the course of the year.

None of the approval games were submitted by Tencent or its rival NetEase. Both companies have been waiting 11 months for any of their upcoming games to be given the green light.

In its most recent financial results, Tencent reported revenues from domestic games, led by Honor of Kings, dipped 1% to $4.9 billion. These account for 24% of the internet firm's total quarterly revenues.

However, the company saw 4% growth in revenues from games outside China at $1.6 billion -- 8% of total quarterly revenues. Tencent no doubt hopes to boost this further and offset the limitations of its home market by bringing its top title to global markets.

This is not the first time the company has attempted this, though. In 2017, Tencent launched Arena of Valor, an international edition of Honor of Kings, with the aim of recreating its success overseas and taking on Western hits like League of Legends (developed by Riot Games, which is wholly owned by Tencent).

The game generated $15 million in its first year, although struggled to gain traction -- to the point where there were reports Tencent were planning to give up on the game just one year later.

Writing for GamesIndustry.biz in 2018, Mintegral's Jeff Sue explored why Arena of Valor struggled in America.

This is also not Tencent's first attempt to establish the Honor of Kings brand outside China. Back in November, the company announced its TiMi Studios Group is working on Honor of Kings: World, a AAA spin-off for consoles and PC.

Shrinking Hello Group Targets Tantan Breakeven in 2023

More than a year after kicking off a major overhaul at one of its two main units, dating app operator Hello Group (MOMO.US), often called the "Tinder of China," is saying it still needs time to return to a growth track.To get more news about tantan topup, you can visit topuplive.com official website.

That's the big picture coming from the company's latest quarterly earnings, which show its revenue continued to shrink in the second quarter, extending a streak dating back to early 2020. It predicted its third quarter revenue will continue sliding by at least 14.9%, similar to the 15.3% decline it posted for the three months through June, according to the announcement released last Thursday.

During an investor call after the results release, management also said the company would continue using its ongoing retrenchment strategy by "prioritizing growth with profit instead of growth (at any) cost.". Under that strategy, the company has tightened its belt across business lines, while cautiously expanding into newer areas.

We'll delve into that strategy shortly and analyze what it means for the company's longer-term development. But first let's review some of the details from its latest financial report, starting with a 26% decline in Hello Group's net profit to 345.6 million yuan ($50.1 million) in the second quarter on revenues of 3.1 billion yuan. The company attributed its sluggish business partly to the resurgence of Covid-19 in China during the period, saying it "brought many challenges and uncertainties to the overall market environment and our execution of strategic goals."

China's tightening regulation of livestreaming businesses with new rules implemented early this year also dealt a heavy blow to the company. Its "live video service" revenue - responsible for about half of its total - fell nearly 30% to 1.5 billion yuan year-on-year during the latest quarter. Hello's platforms allow broadcasters to accept virtual gifts from viewers, with Hello taking a cut. The regulation released in March contained strict guidelines on such gifting, including a cap on how much money a broadcaster can accept, thereby also limiting that revenue source for Hello.

Investors gave Hello's latest earnings a muted thumbs-up, with its stock edging up slightly by 3% in the two trading days after the results were announced. But the company's Friday's closing price of $5.32 is just a fraction of the more than $50 it reached at its high in June 2018, and is well below its IPO price of $13.50 from 2014.

Hello's downward trend follows a similar pattern for most U.S.-listed Chinese companies over the past year on delisting concerns and a series of regulatory crackdowns launched by the Chinese government targeting data-rich companies. But it's also valid to say waning investor appetite for Hello owes to its own struggles over the past two years as its business fails to grow.

In terms of valuation, Hello now trades at a price-to-earnings (P/E) ratio of just 4.5, which is quite cheap compared with peers both at home and abroad. Chinese social media giant Weibo Corp. (WB.US; 9898.HK) trades at 14.5 times and Match Group (MTCH.US), owner of the original Tinder, trades at a whopping 157 times.

The screw pump: Function, areas of application and special features

"Screw pump" is short for eccentric screw pump. After the inventor, it is also known as the Moineau pump , or from English as the PCP pump (progressive or progressing cavity pump). It is one of the rotating positive displacement pumps. The pumped medium is transported from the upper tank through the hose to the spray lance.To get more news about SEEPEX Pump Parts, you can visit hw-screwpump.com official website.

The eccentric screw pump has two main components: on the one hand the rotor, a rotating screw, and on the other hand the stator, a cylinder in which the rotor is located.

The stator has a similar internal geometry to the rotor ,both are helical. When the rotor rotates in the stator, defined empty spaces (conveying chambers) with circumferential sealing result, thus creating a negative pressure. This in turn ensures that the eccentric screw pump is self-priming. Due to the constant movement of the rotor (in contrast to changes in direction of reciprocating pistons and thus corresponding dead centres), material conveying is low in pulsation. At the injection lance, the medium is then divided with the aid of compressed air and can be applied evenly.

Valves for limiting the delivery spaces do not exist in this pump, which means less wear. The rotor moves eccentrically, which means that the axis of rotation of the rotor does not correspond to the axis of symmetry of the complete pump. This is also where the name of the eccentric wrom pump comes from. The eccentric screw pump should not be confused with the Archimedes screw, which is also called a screw pump and is used today especially in the conveyance of solids such as bulk materials. This is a huge helix that simply pushes the conveying elements (often solids) upwards in a trough. There is no stator in which negative pressure is generated, so that this type of material conveying does not belong to the pumps, but is a constant pressure hoist. It was originally used as a water lifting device in ancient times to pump water.
Due to the rotor-stator principle, the WAGNER screw pumps are very easy to operate and infinitely variable and are also suitable for beginners in the field of machine processing. We also make a point of ensuring that our machines are as trouble-free and easy to use as possible for your users - accordingly, WAGNER mortar spraying equipment can be dismantled and reassembledin just a few steps, even on theconstruction site itself. All the wetted parts are made from stainless steel.In addition, our PlastCoat and PlastMax units have a long service life.They are very robust and particularly low-wear and low-maintenance, and the uncomplicated operation avoids sources of error and thus potential for damage. Our WAGNER screw pump also works much more quietly than the standard piston pump!

The screw pump combines many advantageous features of other pump solutions: Like the centrifugal pump, for example, it has no pressure or suction valves, and like a piston pump, the eccentric screw pump also has excellent pumping speed. The flow rate is constant and speed-dependent.Like a gear or screw pump, it handles pumped material with high viscosity, grain size,fibres and inhomogeneous or abrasive materials.

Spraying particularly heavy materials such as plaster or filler is hard work. The biggest advantage of a screw pump is the possibility of achieving a high working speed and yet a high-quality surface result with little physical effort due to the machine processing . The quality of your work does not decrease, on the contrary, and in addition you can plaster, fill, coat or reinforce surfaces much faster. The more surface area involved, the more obvious the time and material savings.

DOES YOUR PROGRESSIVE CAVITY PUMP NOT START?

These positive displacement screw pumps are great for moving thick paste-like fluids at an even speed and pressure but are often problematic with abrasive and aggressive waste-streams.To get more news about Screw pump rotor, you can visit hw-screwpump.com official website.

Whatever your application, if you have an issue with a faulty progressive cavity pump try this checklist for possible solutions.

Here's our trouble-shooter for a variety of progressive cavity pump (screw-pump) issues:

Check the power supply matches the pump motor voltage and amps.
Check that the fuses haven't blown.
Has the pump been idle for some time? The rotor and stator may have ‘bonded', if it doesn't turn then check for dried debris and lubricate with an appropriate oil or glycerin.
Has the cable or its connections been damaged? If so, have the damaged section replaced.
Check that the motor windings haven't burnt out.
Have the pumped fluid's properties changed? Tight tolerances on progressive cavity pumps mean that if the media's viscosity or temperature do not match the pump's specification it can lead to thermal expansion. This could burn the rotor and stator where they rub or even jam it, stopping all movement and putting strain on the motor.
Examine the rotor to make sure it's not blocked or jammed. If it is, then withdraw it from the pump, clean down and if there is no damage evident, reassemble.
Try reducing the pump's rotation speed before switching it on, also check the delta start settings if it is an older 3-phase motor, or invertor settings on a newer 3-phase. Generally, the larger the motor, the longer the time delay between start up and full power is needed. If the pump starts okay on a low speed, wait until it has discharged steadily for a time before increasing speed step-by-step to normal operation.
IS THE PUMP GIVING TOO LITTLE OUTPUT?

Check the feed intake is supplied and that the pump's inlet is fully submerged. Stop the pump and isolate the power while you check for blockages at either end.
Check the motor is rotating in the correct direction. If not, the wiring needs correcting before it is started up again.
Has performance reduced over time? Check the wear parts and replace them if worn out. Progressive cavity pumps rely on tight tolerances and abrasive slurries can soon wear down the stator walling and rotor edges.
Examine the discharge pipework and replace it if leaking or cracked.
Another reason why the pump may be giving too little output is if the final discharge head is too high; where this is the case, you may need to use a larger pump or an alternative type.
Check that the rotation speed is correct. Reduced speed for the same power draw could indicate something jamming inside the pump, or the fluid's viscosity is too high for the pump configuration.
