What is ethereum and how does it differ from Bitcoin?

E thereum is a rising star in the cryptocurrency world. It has quickly become the second largest digital currency in just over two years, booming in value and spurring the rise of hundreds of new rivals to Bitcoin.

Launched in 2015, the value of ether (ethereum's currency) has increased rapidly. It hit highs of $1400 in January before showing intense volatility, slumping to less than $400 and then rebounding to about $700.

But to put it all in context, last year saw near continual growth in cryptocurrencies like Bitcoin and Litecoin. Ethereum started the year trading for about $10 per coin.

Ethereum bitcoin

What is the main difference?

Well, the fact that Ethereum was created from Bitcoin open-source says a lot about the basic differences between the two of them; the first one is actually the very first cryptocurrency in the world so is the most known, installed and houses any kind of users and investors. On the other side, Ethereum is one of the newest cryptocurrencies but despite that, it quickly positioned right after BTC thanks to its diverse platform that might not be very friendly for the newest users but it is slowly getting more approachable for them as it is quite useful for the most expert traders.

Is in that Ethereum platform where the primordial difference between Ether and Bitcoin is. As BTC is the first cryptoasset, the chainblock was newly developed and though only in relation to the cryptocoin trade, period, that is its final object in order to maintain a relatively stable e-currency. Ethereum, on the contrary, is an integrated platform where users can develop other projects and transactions besides trading cryptocurrencies.

Ether is not only one of the concepts this platform seeks to develop and, as the system grows, it is possible that other cryptocurrencies depend on Ethereum as they do now on Bitcoin. But the smart contracts are what gives Ethereum so much popularity in this short time.
Other differences

In smaller aspects, as Ethereum is newer and therefore has a more modern technology, it surpasses BTC system in some tiny factors:

• Time for transaction confirmation: Bitcoin’s time for confirmation is one of the slowest ones with an average of 10 minutes per transaction while Ethereum works in around 12 seconds thanks to its GHOST protocol.

• Monetary supply: Bitcoin has a quite limited stash that is actually getting to its limits while Ethereum supply is quite greater than BTC’s and is not nearly to its limits, actually it is said that Ether has no total limit and can be created as much of it as necessary, only an annual limit of 18USD million is set.

• The mining reward is quite different too; Bitcoin is quite simpler to mine and has a reward around 12BTC per transaction but it is constantly diminishing with time. On the other hand, Ethereum rewards are lower, only 5ETH per transaction but it seems to be much more stable.

• The cost of transaction: in Bitcoin, every transaction competes equally with each other while in Ethereum, the costing is directly related to the storage needs.

• Turing internal code: unlike Bitcoin, Ethereum counts with its own Turing internal and integral code which gives the possibility to perform any calculation if we have the time and right equipment. Bitcoin is a little bit more uncertain in this aspect.

Ethereum Vs Bitcoin: What's The Main Difference?

While Bitcoin has long been dominant in the cryptocurrency scene, it is certainly not alone. Ethereum is another cryptocurrency related project that has attracted a lot of hype because of its additional features and applications.

Ethereum: More Than Just Money

The first thing about Ethereum is that it is not just a digital currency. It is a blockchain-based platform with many aspects. It features smart contracts, the Ethereum Virtual Machine (EVM) and it uses its currency called ether for peer-to-peer contracts.

Ethereum's smart contracts use blockchain stored applications for contract negotiation and facilitation. The benefit of these contracts is that the blockchain provides a decentralized way to verify and enforce them. The decentralized aspect makes it incredibly difficult for fraud or censorship. Ethereum's smart contracts aim to provide greater security than traditional contracts and bring down the associated costs.

The smart contract applications are powered by ether, Ethereum's blockchain based cryptocurrency. Ether, as well as other crypto-assets, are held in the Ethereum Wallet, which allows you to create and use smart contracts. The system has been described by the New York Times as..

"a single shared computer that is run by the network of users and on which resources are parceled out and paid for by ether."

Implement Smart Contracts With Your Own Cryptocurrency

Ethereum allows you to create digital tokens that can be used to represent virtual shares, assets, proof of membership and more. These smart contracts are compatible with any wallet, as well as exchanges that use a standard coin API. You can copy the code from Ethereum's website and then use your tokens for many purposes, including the representation of shares, forms of voting and also fundraising. You can either have a fixed amount of tokens in circulation or have a fluctuating amount based on predetermined rules.

You Don't Need Kickstarter When You Have Ethereum

One great feature of Ethereum is that it gives developers a means to raise funds for various applications. For your new project, you can set up a contract and seek pledges from the community. The money that is raised will be held until the goal is reached or until an agreed upon date. The funds will be released back to the contributors if the goal is not met, or go on to the project if it is successful. Kicking out Kickstarter means that the third party is taken out, along with their rules, and also the fees they charge (when you include processing fees, Kickstarter can take up to 10% of a project's budget).

Skip the Traditional Management Structure With Democratic Autonomous Organizations

Not only can Ethereum help you source funding, but it can also help to provide the organizational structure to get your idea off the ground. You can collect proposals from the people who backed your project and then hold votes on how you should proceed. This means that you can skip the expense of a traditional structure, such as hiring managers and doing paperwork. Ethereum also protects your project from outside influences, while its decentralized network means that you won't face downtime.

The Finer Details: Differences Between Ethereum and Bitcoin

There are also many smaller aspects that differ between the two blockchain-based projects. Bitcoin's average block time is about 10 minutes, while Ethereum's aims to be 12 seconds. This quick time is enabled by Ethereum's GHOST protocol. A faster block time means that confirmations are quicker. However, there are also more orphaned blocks.

Another key difference between them is their monetary supply. More than two-thirds of all available bitcoin have already been mined, with the majority going to early miners. Ethereum raised its launch capital with a presale and only about half of its coins will have been mined by its fifth year of existence.

The reward for mining Bitcoin halves about every four years and it is currently valued at 12.5 bitcoins. Ethereum rewards miners based on its proof-of-work algorithm called Ethash, with 5 ether given for each block. Ethash is a memory hard hashing algorithm, which encourages decentralized mining by individuals, rather than the use of more centralized ASICs as with Bitcoin.

Bitcoin and Ethereum also cost their transactions in different ways. In Ethereum, it is called Gas, and the costing of transactions depends on their storage needs, complexity and bandwidth usage. In Bitcoin, the transactions are limited by the block size and they compete equally with each other.

Ethereum features its own Turing complete internal code, which means that anything can be calculated with enough computing power and enough time. Bitcoin does not have this capability. While there are certainly advantages to the Turing-complete, its complexity also brings security complications, which contributed to the DAO attack in June.

Ethereum and Bitcoin: Two Very Different Beasts

While many will compare the cryptocurrency aspect of both Ethereum and Bitcoin, the reality is that they are vastly different projects and have different intentions. Bitcoin has emerged as a relatively stable digital currency, while Ethereum aims to encompass more, with ether just a component of its smart contract applications.

Repair the Yahoo Search App.

Yahoo Search App from the Google Play Store on my Samsung Galaxy S8+ phone stopped working on May 18, 2018.

I went to the Yahoo Troubleshooting page but the article that said to do a certain 8 steps to fix the problem with Yahoo Services not working and how to fix the problem. Of course they didn't work.

I contacted Samsung thru their Samsung Tutor app on my phone. I gave their Technican access to my phone to see if there was a problem with my phone that stopped the Yahoo Search App from working. He went to Yahoo and I signed in so he could try to fix the Yahoo Search App not working. He also used another phone, installed the app from the Google Play Store to see if the app would do any kind of search thru the app. The Yahoo Search App just wasn't working.

I also had At&t try to help me because I have UVERSE for my internet service. My internet was working perfectly. Their Technical Support team member checked the Yahoo Search App and it wouldn't work for him either.

We can go to www.yahoo.com and search for any topic or website. It's just the Yahoo Search App that won't allow anyone to do web searches at all.

I let Google know that the Yahoo Search App installed from their Google Play Store had completely stopped working on May 18, 2018.

I told them that Yahoo has made sure that their Yahoo members can't contact them about anything.

I noticed that right after I accepted the agreement that said Oath had joined with Verizon I started having the problem with the Yahoo Search App.
No matter what I search for or website thru the Yahoo Search App it says the following after I searched for
www.att.com.

I tried to search for things like www.homedepot.com. The same thing happened. It would say WEBPAGE NOT AVAILABLE. The only thing that changed were all the upper and lower case letters, numbers and symbols.
Then it would again say

This is the same thing that happened when Samsung and At&t tried to do any kind of searches thru the Yahoo Search App.

Yahoo needs to fix the problem with their app.

Ethereum, a Virtual Currency, Enables Transactions That Rival Bitcoin’s

A new virtual gold rush is underway.

Even as Bitcoin, riven by internal divisions, has struggled, a rival virtual currency — known as Ethereum — has soared in value, climbing 1,000 percent over the last three months.

Beyond the price spike, Ethereum is also attracting attention from giants in finance and technology, like JPMorgan Chase, Microsoft and IBM, which have described it as a sort of Bitcoin 2.0.

The rise of the relatively new virtual currency has been helped by a battle within the Bitcoin community over how the basic Bitcoin software should develop.

The fights have slowed down Bitcoin transactions and led some people to look for alternative virtual currencies to power their businesses. Enter Ethereum.

Like Bitcoin, the Ethereum system is built on a blockchain in which every transaction is recorded publicly. The promise of such a system is that it allows the exchange of money and assets more quickly and more cheaply than relying on a long chain of middlemen.

But Ethereum has also won fans with its promise to do much more than Bitcoin. In addition to the virtual currency, the software provides a way to create online markets and programmable transactions known as smart contracts.

The system is complicated enough that even people who know it well have trouble describing it in plain English. But one application in development would let farmers put their produce up for sale directly to consumers and take payment directly from consumers. There are already dozens of functioning applications built on Ethereum, enabling new ways to manage and pay for electricity, sports bets and even Ponzi schemes.

All of this work is still very early. The first full public version of the Ethereum software was recently released, and the system could face some of the same technical and legal problems that have tarnished Bitcoin.

Many Bitcoin advocates say Ethereum will face more security problems than Bitcoin because of the greater complexity of the software. Thus far, Ethereum has faced much less testing, and many fewer attacks, than Bitcoin. The novel design of Ethereum may also invite intense scrutiny by authorities given that potentially fraudulent contracts, like the Ponzi schemes, can be written directly into the Ethereum system.

But the sophisticated capabilities of the system have made it fascinating to some executives in corporate America. IBM said last year that it was experimenting with Ethereum as a way to control real world objects in the so-called Internet of things.

Microsoft has been working on several projects that make it easier to use Ethereum on its computing cloud, Azure.

“Ethereum is a general platform where you can solve problems in many industries using a fairly elegant solution — the most elegant solution we have seen to date,” said Marley Gray, a director of business development and strategy at Microsoft.

Mr. Gray is responsible for Microsoft’s work with blockchains, the database concept that Bitcoin introduced. Blockchains are designed to store transactions and data without requiring any central authority or repository.

Blockchain ledgers are generally maintained and updated by networks of computers working together — somewhat similar to the way that Wikipedia is updated and maintained by all its users.

Many corporations, though, have created their own Ethereum networks with private blockchains, independent of the public system, and that could ultimately detract from the value of the individual unit in the Ethereum system — known as an Ether — that people have recently been buying.

The interest in Ethereum is one sign of the corporate fascination with blockchains. Most major banks have expressed an interest in using them to make trading and money transfer faster and more efficient. On Tuesday, executives from the largest banks will gather for a conference, “Blockchain: Tapping Into the Real Potential, Cutting Through the Hype.”

Many of these banks have recently been looking at how some version of Ethereum might be put to use. JPMorgan, for instance, has created a specific tool, Masala, that allows some of its internal databases to interact with an Ethereum blockchain.

Michael Novogratz, a former top executive at the private equity firm Fortress Investing Group, who helped lead Fortress’s investment in Bitcoin, has been looking at Ethereum since he left Fortress last fall. Mr. Novogratz said that he made a “significant” purchase of Ether in January. He has also heard how the financial industry’s chatter about the virtual currency has evolved.

“A lot of the more established players were thinking, ‘It’s still an experiment,’ ” he said. “It feels like in the last two to three months that experiment is at least getting a lot more validation.”

Since the beginning of the year, the value of an individual unit of Ether has soared as high as $12 from around $1. That has brought the value of all existing Ether to over $1 billion at times, significantly more than any virtual currency other than Bitcoin, which had over $6 billion in value outstanding last week.

Since Bitcoin was invented, there have been many so-called alt-coins that have tried to improve on Bitcoin, but none have won the following of Ethereum.

Unlike Bitcoin, which was released in 2009 by a mysterious creator known as Satoshi Nakamoto, Ethereum was created in a more transparent fashion by a 21-year-old Russian-Canadian, Vitalik Buterin, after he dropped out of Waterloo University in Ontario.

The most basic aim of Ethereum was to make it possible to program binding agreements into the blockchain — the smart contract concept. Two people, for instance, could program a bet on a sports game directly into the Ethereum blockchain. Once the final score came in from a mutually agreed upon source — say, The Associated Press — the money would be automatically transferred to the winning party. Ether can be used as a currency in this system, but Ether are also necessary to pay for the network power needed to process the bet.

The Ethereum system has sometimes been described as a single shared computer that is run by the network of users and on which resources are parceled out and paid for by Ether.

A team of seven co-founders helped Mr. Buterin write up the software after he released the initial description of the system. Mr. Buterin’s team raised $18 million in 2014 through a presale of Ether, which helped fund the Ethereum Foundation, which supports the software’s development.

Like Bitcoin, Ethereum has succeeded by attracting a dedicated network of followers who have helped support the software, partly in the hope that their Ether will increase in value if the system succeeds. Last week, there were 5,800 computers — or nodes — helping support the network around the world. The Bitcoin network had about 7,400 nodes.

One of Mr. Buterin’s co-founders, Joseph Lubin, has set up ConsenSys, a company based in Brooklyn that has hired over 50 developers to build applications on the Ethereum system, including one that enables music distribution and another that allows for a new kind of financial auditing.

The ConsenSys offices are in an old industrial building in the Bushwick section of Brooklyn. The office is essentially one large room, with all the messy trademarks of a start-up operation, including white boards on the walls and computer parts lying around.

Mr. Lubin said he had thrown himself into Ethereum after starting to think that it delivered on some of the failed promise of Bitcoin, especially when it came to allowing new kinds of online contracts and markets.

“Bitcoin presented the broad strokes vision, and Ethereum presented the crystallization of how to deliver that vision,” he said.

Joseph Bonneau, a computer science researcher at Stanford who studies so-called crypto-currencies, said Ethereum was the first system that had really caught his interest since Bitcoin.

It is far from a sure thing, he cautioned.

“Bitcoin is still probably the safest bet, but Ethereum is certainly No. 2, and some folks will say it is more likely to be around in 10 years,” Mr. Bonneau said. “It will depend if any real markets develop around it. If there is some actual application.”

Ethereum is top public blockchain, bitcoin No. 13 in China's new index

NEW YORK (Reuters) - Ethereum is the top public blockchain in the cryptocurrency space, while that of bitcoin, the original virtual currency, is ranked 13th, according to the Chinese government’s first monthly Global Public Chain Assessment Index released on Thursday.

The index was created and released by the China Center for Information Industry Development, part of the Ministry of Industry and Information Technology in Beijing. It evaluates the technological capability, usefulness of the application, and innovativeness of the project.

Blockchain, the system powering cryptocurrencies like bitcoin, is a shared database that is maintained by a network of computers connected to the internet.

Ethereum, whose currency is called ether, garnered an overall score of 129.4. It has the become the foundation for many initial coin offerings, in which start-ups create their own digital currencies and sell them to investors to generate financing for their projects.

Bitcoin, founded nearly 10 years ago, had a rating of 88 and came in at No. 13.

Blockchain projects Steem, Lisk, NEO and Komodo took second, third, fourth, and fifth place, respectively, with scores of 115.9, 104.8, 103.0 and 101.5.

The index, which has 28 blockchain projects with their corresponding cryptocurrencies, will be updated monthly.

The sector currently has more than 1,500 cryptocurrencies, with total market capitalization of nearly $380 billion, according to digital currency tracker coinmarketcap.com.

Bitcoin, the largest of the digital currencies, last traded at $8,153.39 BTC=BTSP on the BitStamp platform. Ethereum was down 1.4 percent at $689.62.

China in general sees blockchain technology as an active area of innovation and expects public blockchains and decentralized applications to become significant parts of the future economy. In the second half of last year, though, the Chinese government started to crack down on illegal initial coin offerings.

China was the most active filer of blockchain patent applications last year, according to data collated by Thomson Reuters’ Practical Law from the World Intellectual Property Organization database.

Bitcoin, Ethereum or Litecoin: Which is best for you?

A primer on the most visible cryptocurrencies.

Before you jump into this overview of a few cryptocurrency alternatives, check out our first two articles in this series, Bitcoin, explained and Buying and selling bitcoin.

Bitcoin has spawned hundreds of cryptocurrencies.

Karen Bleier/AFP/Getty Images

Bitcoin was the first. Since its release in 2009, it's become the most famous, established and valuable cryptocurrency. But it's not the only game in town.

Litecoin followed in 2011. Created by Charles Lee, an engineer who later helped build Coinbase, the leading cryptocurrency exchange, Litecoin is based on the same code as bitcoin but with a few tweaks designed to address two of its predecessor's limitations: transaction speed and access to the mining process.

And in 2015, Ethereum made its debut, incorporating bitcoin's basic blockchain premise and Litecoin's pursuit of faster transaction speed, but adding a few of its own twists -- including the ability to process little chunks of code, called "smart contracts" -- and on its virtual peer-to-peer network as opposed to a dedicated server or mining rig.

Ripple's market cap now exceeds $40 billion.

Coinbase's support for bitcoin, Litecoin and Ethereum -- as well as Bitcoin Cash, a new branch of the bitcoin blockchain created in August 2017 -- helped install and keep them among the most visible and well-capitalized cryptocurrencies. Rounding out the top 10, in terms of market capitalization, is a dynamic shortlist that has included established coins and upstarts like Ripple, Cardano, Neo, Stellar, Eos and IOTA.

For the purposes of introducing some of the prevailing concepts behind the growing population of cryptocurrencies, we'll take a closer look at the technologies behind Litecoin and Ethereum, how they compare to bitcoin and what they each bring to the table for prospective investors, miners and traders.

The top six cryptocurrencies represented roughly $315 billion in market capitalization as of Feb. 12, 2018.

Litecoin 101

Litecoin is closely based on bitcoin -- they're built on the same underlying code -- but with a few distinctive tweaks. The central difference is that Litecoin is mined using the Scrypt algorithm, which is rooted in mathematical computations that are simpler than those used by bitcoin's SHA-256 algorithm. As a result, in contrast to the specialized, super-expensive, energy-intensive mining rigs required to mine bitcoin, you can mine Litecoin with a decent laptop or desktop PC, especially if it's tricked out with a powerful graphics card.

And because Scrypt is less mathematically complex than SHA-256, Litecoin mining is way faster than bitcoin mining. A Litecoin block takes only 2.5 minutes to hash, compared to the 10 minutes it takes to hash a bitcoin block. So Litecoin transactions are also faster to process and confirm.

Ethereum 101

Like Litecoin, it's based on the same fundamental blockchain concept as bitcoin, with blocks and hashes and such, but Ethereum adds its own distinctive twist. Funded in 2014 through an initial coin offering , Ethereum fancies itself "an enormously powerful shared global infrastructure" that, in addition to serving as a digital currency, runs special applications called "smart contracts."

This collective, distributed computing network, called the "Ethereum Virtual Machine," can be, in a sense, rented out. Participants who consume computing power pay for it with tokens, called Ether; those who contribute processing power can earn them. Of course, buyers and sellers can simply trade Ether independently of these activities.

Consider that bitcoin mining is akin to thousands of chefs feverishly racing to prepare a new, extremely complicated dish -- and only the first one to serve up a perfect version of it ends up getting paid. In the Ethereum kitchen, miners serve as the restaurant's landlord, compensated for providing the infrastructure so that Ether chefs can invent new types of cuisine.

In fact, a group of companies and universities has formed a nonprofit expressly to legitimize Ethereum; promote it as an open-source platform and not a commercial enterprise per se; and develop and support those applications that run on it. And these are not rinky-dink startups -- we're talking about major technology players like Intel and Microsoft and financial behemoths like JP Morgan and Credit Suisse.

Which cryptocurrency is the most valuable?

Bitcoin remains the most visible and frequently traded cryptocurrency. After a remarkable surge in November 2017, it crested at just shy of $20,000 in late December 2017, and after settling in around $15,000 for a few weeks, shed another 50 percent of its value after South Korean regulators publicly mulled banning trading. The price of Litecoin, sometimes referred to as the "silver" to bitcoin's "gold," followed a valuation trend similar to bitcoin and now sits at around $160. Though all three have increased in value during the past 12 months, Ethereum has charted its own distinct path, spiking in June 2017 and surpassing $1,000 in early January 2018.

Which one's the best for you?

If only it was that easy. No one knows whether any cryptocurrency will increase in value -- or even be around in a year's time (though we think the ones outlined in this article will check both of those boxes). None of them are regulated (yet) and only individuals with the highest capacity for risk should get into the cryptocurrency market. That noted, there are significant differences among these three that could be used to form a rational basis for investing in or mining one over another.
