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

What is Bitcoin?

With the Bitcoin price so volatile everyone is curious. Bitcoin, the category creator of blockchain technology, is the World Wide Ledger yet extremely complicated and no one definition fully encapsulates it. By analogy it is like being able to send a gold coin via email. It is a consensus network that enables a new payment system and a completely digital money.

It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. Bitcoin was the first practical implementation and is currently the most prominent triple entry bookkeeping system in existence.

Who created Bitcoin?

The first Bitcoin specification and proof of concept was published in 2009 by an unknown individual under the pseudonym Satoshi Nakamoto who revealed little about himself and left the project in late 2010. The Bitcoin community has since grown exponentially.

Satoshi's anonymity often raises unjustified concerns because of a misunderstanding of Bitcoin's open-source nature. Everyone has access to all of the source code all of the time and any developer can review or modify the software code. As such, the identity of Bitcoin's inventor is probably as relevant today as the identity of the person who invented paper.

Who is involved in Bitcoin?

Over $1B of investment into Bitcoin and blockchain companies has taken place resulting in thousands of companies and hundreds of thousands of individuals involved from around the world.

What is the Blockchain?

Who controls the Bitcoin network?

Nobody owns the Bitcoin network much like no one owns the technology behind email or the Internet. Bitcoin transactions are verified by Bitcoin miners which has an entire industry and Bitcoin cloud mining options. While developers are improving the software they cannot force a change in the Bitcoin protocol because all users are free to choose what software and version they use.

In order to stay compatible with each other, all users need to use software complying with the same rules. Bitcoin can only work correctly with a complete consensus among all users. Therefore, all users and developers have a strong incentive to protect this consensus.

How does Bitcoin work?

From a user perspective, Bitcoin is nothing more than a mobile app or computer program that provides a personal Bitcoin wallet and enables a user to send and receive bitcoins.

Behind the scenes, the Bitcoin network is sharing a massive public ledger called the "block chain". This ledger contains every transaction ever processed which enables a user's computer to verify the validity of each transaction. The authenticity of each transaction is protected by digital signatures corresponding to the sending addresses therefore allowing all users to have full control over sending bitcoins.

Thus, there is no fraud, no chargebacks and no identifying information that could be compromised resulting in identity theft. To learn more about Bitcoin, you can consult the original Bitcoin whitepaper, read through the extremely thorough Frequently Asked Questions, listen to a Bitcoin podcast or read the latest Bitcoin news.

Sponsors for free Bitcoins

Many people new to Bitcoin are curious about how to get some. Bitcoin faucets, places where bitcoins are given away for free, have been a part of spreading Bitcoin since the earliest days. But one problem is running out of bitcoins to give! That is why we have figured out a sustainable way to give away free bitcoins with sponsors.

Bitcoin Smart Banknotes Launched in Singapore

A digital asset smart banknote manufacturer has launched bitcoin banknotes at a store in Singapore. Designed to make owning and circulating cryptocurrencies as easy as using paper money, they are currently available in denominations of 0.01 and 0.05 BTC.

Bitcoin Banknotes Debut in Singapore

Digital asset banknote manufacturer Tangem announced the launch of smart bitcoin banknotes at the Megafash Suntec City store in Singapore on Thursday.

Megafash store in Singapore.

The announcement states:

Available immediately in denominations of 0.01 and 0.05 BTC, Tangem Notes radically improve the simplicity and security of acquiring, owning, and circulating cryptocurrencies for both sophisticated and incoming users.

With headquarters in Switzerland’s cryptovalley Zug and Hong Kong, Tangem also has offices in Singapore, Moscow, and China, according to its website.

The company says it “is delivering the first shipment of 10,000 production notes to prospective partners and distributors around the world for commercial pilots.”

How Tangem’s Smart Banknotes Work

Tangem explains that their bitcoin smart banknotes are “Comparable to a well-protected paper banknote” and “Cheap enough to hand over.” Citing their ease of use, the company says there is “No special infrastructure, no complicated applications – just touch the banknote with an NFC-capable smartphone to be 100% sure it has valid assets.”

Illustration of how the banknotes work.

Transferring ownership of the notes is anonymous and instant, Tangem claims. “Physically hand over the whole wallet together with the blockchain private key. No transaction fees, no need to await confirmation blockchain.” Moreover, the company says that its banknotes are equipped with “high-grade EAL6+ protection for all cryptocurrencies. Irretrievable private keys prohibit replication of wallet and its assets.”

Competitor Opendime has long offered a physical product with a similar purpose but shaped more like a USB thumb drive and without any amount printed on them.

Security Questions

Tangem’s hardware is based on Samsung Semiconductor’s S3D350A chip. The company claims to offer “the first hardware storage solution on the market with its entire electronics and cryptography certified to the Common Criteria EAL6+ and EMVCo security standards.”

As with any embedded firmware-based product in the cryptocurrency space, security audits and open-source code are paramount to earning users’ trust to ensure that the company does not have access to the funds stored on their product. At the time of this writing, Tangem’s only publicly available code is for its iOS and Android apps on Github.

However, the company claims that it has shared the full source code of its proprietary chip firmware with a Swiss security firm, Kudelski Group, adding that this firm has completed an in-depth review and comprehensive security audit of its product’s architecture.

How does Bitcoin work?

This is a question that often causes confusion. Here's a quick explanation!

The basics for a new user

As a new user, you can get started with Bitcoin without understanding the technical details. Once you have installed a Bitcoin wallet on your computer or mobile phone, it will generate your first Bitcoin address and you can create more whenever you need one. You can disclose your addresses to your friends so that they can pay you or vice versa. In fact, this is pretty similar to how email works, except that Bitcoin addresses should only be used once.


Balances - block chain

The block chain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography.

Transactions - private keys

A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast between users and usually begin to be confirmed by the network in the following 10 minutes, through a process called mining.

Processing - mining

Mining is a distributed consensus system that is used to confirm waiting transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent previous blocks from being modified because doing so would invalidate all following blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively in the block chain. This way, no individuals can control what is included in the block chain or replace parts of the block chain to roll back their own spends.

Going down the rabbit hole

This is only a very short and concise summary of the system. If you want to get into the details, you can read the original paper that describes the system's design, read the developer documentation, and explore the Bitcoin wiki.

Video Explains Bitcoin In Less Than 4 Minutes

The digital currency Bitcoin might seem like a baffling trend. But tech geek Mark Fennell and cartoonist Duncan Elms are here to help.

Fennell and Elms took time between their day jobs to make "Bitcoin Explained," a video explanation of the digital currency. The video launched on April 7, a day before the value of all Bitcoins reached more than $2 billion and two days before the price of one Bitcoin reached $200.

To summarize the video, Bitcoin is a digital currency that's not backed by any government. Instead, it's engineered to operate like a commodity currency. The units are "mined" by computers with spare processing power, and 50 Bitcoins are mined approximately every 10 minutes, thus lending a measure of artificial stability to the currency. Only 21 million Bitcoins will ever exist, according to the currency's pseudo-anonymous developer, yet only about half of those have been mined thus far.

Though we take issue with the video seemingly equating the Dark Web (the parts of the Internet that can only be accessed anonymously) with the Silk Road (a marketplace that exists on the Dark Web), it does a decent job of explaining the digital currency that's been making waves in recent weeks. The untraceable coin has been gaining traction in Cyprus, as the bailout there makes people question the security of the banking system. It's even supposedly left a few lucky millionaires in its wake.

Not bad for something once considered the currency of "nerds, conspiracy theorists and shady Internet characters."

14 Best Bitcoin Wallets For Secure Bitcoin Storage

Here’s something every bitcoin owner should know: the safety and security of your bitcoins is ultimately your responsibility.

Combining digital security knowledge as well as secure bitcoin storage is important if you don’t want your accounts hacked and bitcoins drained. Remember – bitcoin transactions are not reversible. To send or spend bitcoins, one must have access to both public and private keys. Private keys, especially, must be protected.

Types of Bitcoin Wallets

There are a few types of bitcoin wallets and they have varying security mechanism to ensure the safety of private keys.

Simplistically, bitcoin wallets can be divided into 5 types: desktop, mobile, online, hardware and paper wallets. Some types may overlap or used in combination with each other. I’m going to touch on what to expect from each type and feature a few examples you can try out.

Here are 14 secure bitcoin wallet options you can choose from.

Desktop wallet

  • Bitcoin desktop wallets offer one of the highest (if not the highest) level of security in terms of bitcoin storage.
  • You must download the software to your computer and perform bitcoin transactions from desktops, so it may not be practical for some people.
  • This option can be technical and confusing for bitcoin newbies.
Bitcoin Core

Bitcoin Core is the first and original wallet. Using this option means having control over both your public and private keys, which ensures safe storage.

However, Bitcoin Core also requires a lot of space as the software comes with data on every bitcoin transaction ever performed.

According to the download page, as of 2016 you need 65GB of free space – this number will increase as more bitcoin transactions happen every day.

Just over 30MBs, Multibit is a lightweight desktop bitcoin wallet.

Many people use it together with KeepKey (more about this below), a USB device that requires your manual confirmation before any bitcoins can be transacted.

Calling themselves ‘The Only Open-Source Wallet With Cold Storage and Multi-Signature Support’, Armory is one of the popular options around for desktop bitcoin wallet.

Private keys are stored in an offline computer, which means that only someone with access to the physical location of the computer (it is kept secret) can steal bitcoins.

Mobile Wallets

  • Bitcoin mobile wallets are not only accessible and practical
  • Many also incorporate other layers of security to ensure users’ bitcoins are not compromised.
  • It is a good idea to keep only a small amount of bitcoins in mobile wallets while keeping the rest in more secure options.

Note: All the recommendations below are available for both Android and iOS users.

Mycelium is one of the safest and most recommended options for secure bitcoin storage on mobile. Boasting ‘bank grade security’, it boasts Hierarchical Deterministic wallets, private key deletion and ‘watch only’ accounts.

This full-fledged bitcoin service provider offers both online and mobile secure bitcoin wallets. What differentiates Wirex from the rest is its ease of use while not compromising security.

Users get multi-signature (‘multi-sig’) wallets and can enable 2-factor authentication (2FA) for both app and Wirex-link email address, making third-party breaches hard.

Famous for its vault and security, Xapo combines cold storage and multi-sig technology to keep users’ bitcoins safe. Its servers are kept ‘behind reinforced concrete walls, a steel blast door and radio wave-blocking Faraday cage’, located ‘within the Alps’.

Online wallets

  • Online bitcoin wallets are wallets that are easily accessibly on the Web via any device so long as it can be connected to the Internet.
  • It is easier and faster to make transactions via online wallets due to its accessibility.
  • Phishing, malware, insider hacking or plain lack of digital security knowledge makes it easy for hackers to steal bitcoins from online wallets.
  • The failure of two huge bitcoin exchanges (Mt Gox and Bitfinex) make people wary of such services.

Although the bitcoin wallets recommended in this section have high reputation, we suggest you keep larger amounts of bitcoins in other types of wallets.

Blockchain.info

Blockchain.info is the most popular (8 mil wallets) website everyone uses to perform and check bitcoin transactions. They are often praised for its ease of use, multi-country support, and cross-platform capability.

Aside from web wallet, Blockchain.info is also available on desktop and mobile app.

A respected name in the Bitcoin world, BitGo is considered a leader in blockchain security. BitGo is great for individuals and businesses who prefer near-instant transactions. Usually, a bitcoin transaction needs between 3-6 confirmations, taking about 30-60 minutes.

With BitGo Instant and its zero-confirmation technology, users can make both secure and fast transactions.

GreenAddress

Many bitcoin holders have the tendency to check bitcoin wallets multiple times to reassure themselves their bitcoins are still there. This constant login-logout might be unsafe if it was done over unsecured WiFi or exposed to malware or phishing tactics.

GreenAddress’s watch-only mode helps users to check balances without compromising safety. Hierarchical Deterministic wallets also help to keep users’ bitcoins secure.

Hardware Wallet

  • The method of choice for many bitcoin holders to keep significant quantities of bitcoins
  • Hardware bitcoin wallets are user-friendly and portable.
  • All of these Plug-and-Play options give users complete control of their own bitcoins.

One of the biggest fears of a bitcoin holder is unknown transaction that depletes all of their bitcoin savings. KeepKey helps to alleviate this fear. Users will have to approve each outgoing transaction on the KeepKey device, manually.

Private keys remain in the device, which is also PIN-protected in case it falls into the wrong hands.

A trusted name and endorsed by many key Bitcoin community leaders, Trezor is small and simple to use. It features security against malware and disaster recovery in case of theft or loss.

Ledger Nano

The smallest and most cost-effective option, the USD-sized Ledger Nano comes in a few variations. Everyday users can select between Ledger Nano or Ledger Nano S. The latter is the first hardware wallet that can also store Ether (ETH/ETH), making it the first of its kind.

Paper Wallet

  • Bitcoin paper wallets are safe against hackers as the bitcoins are brought offline.
  • Users have control of their bitcoins at all times as they keep own private keys.
  • The problem, however, is storage. Paper can be destroyed, torn, fade or otherwise lost.
  • Unlike hardware wallets, there is no recovery mechanism for paper wallets – so lost bitcoins are lost forever. This is something you need to keep in mind if you want to use this option.
BitcoinPaperWallet

Users can print tamper-resistant paper wallets with this services to keep their bitcoins offline. Offering additional security tips, designs and supplies, this website is a favorite among bitcoin cold storage advocates. It even has a handy video showing you how to use this paper wallet.

BitAddress

BitAddress.org is a no-frills free service that can generate bitcoin paper wallets easily.

Conclusion

To a new bitcoin user, this information might seem daunting. You might have heard of bitcoin losses due to hacks, malware, or perhaps simply human error.

We suggest keeping most of your bitcoins in either paper or hardware wallets (or if you have the space, in Bitcoin Core). If you must keep bitcoins in online or mobile wallets, spread them around in a few reputable websites as recommended above.

Bitcoin Smart Banknotes Launched in Singapore

A digital asset smart banknote manufacturer has launched bitcoin banknotes at a store in Singapore. Designed to make owning and circulating cryptocurrencies as easy as using paper money, they are currently available in denominations of 0.01 and 0.05 BTC.

Bitcoin Banknotes Debut in Singapore

Digital asset banknote manufacturer Tangem announced the launch of smart bitcoin banknotes at the Megafash Suntec City store in Singapore on Thursday.

Megafash store in Singapore.

The announcement states:

Available immediately in denominations of 0.01 and 0.05 BTC, Tangem Notes radically improve the simplicity and security of acquiring, owning, and circulating cryptocurrencies for both sophisticated and incoming users.

With headquarters in Switzerland’s cryptovalley Zug and Hong Kong, Tangem also has offices in Singapore, Moscow, and China, according to its website.

The company says it “is delivering the first shipment of 10,000 production notes to prospective partners and distributors around the world for commercial pilots.”

How Tangem’s Smart Banknotes Work

Tangem explains that their bitcoin smart banknotes are “Comparable to a well-protected paper banknote” and “Cheap enough to hand over.” Citing their ease of use, the company says there is “No special infrastructure, no complicated applications – just touch the banknote with an NFC-capable smartphone to be 100% sure it has valid assets.”

Illustration of how the banknotes work.

Transferring ownership of the notes is anonymous and instant, Tangem claims. “Physically hand over the whole wallet together with the blockchain private key. No transaction fees, no need to await confirmation blockchain.” Moreover, the company says that its banknotes are equipped with “high-grade EAL6+ protection for all cryptocurrencies. Irretrievable private keys prohibit replication of wallet and its assets.”

Competitor Opendime has long offered a physical product with a similar purpose but shaped more like a USB thumb drive and without any amount printed on them.

Tangem’s hardware is based on Samsung Semiconductor’s S3D350A chip. The company claims to offer “the first hardware storage solution on the market with its entire electronics and cryptography certified to the Common Criteria EAL6+ and EMVCo security standards.”

As with any embedded firmware-based product in the cryptocurrency space, security audits and open-source code are paramount to earning users’ trust to ensure that the company does not have access to the funds stored on their product. At the time of this writing, Tangem’s only publicly available code is for its iOS and Android apps on Github.

However, the company claims that it has shared the full source code of its proprietary chip firmware with a Swiss security firm, Kudelski Group, adding that this firm has completed an in-depth review and comprehensive security audit of its product’s architecture.
