I have been noticing on many online bitcoin districts that various users are unable to understand the concept of Segregated Witness. This post will clear up any doubts, uncertainties, and myths regarding SegWit.

So, what happens in SegWit?

SegWit is short for Segregated Witness and it’s a proposal presented by the developers of Bitcoin Core. Originally it was aimed to solve the transaction malleability, which is a well-known weak spot in the Bitcoin system. The idea behind SegWit is that the signatures in a transaction, also known as the “witness data” are skipped when calculating the transaction id.

Basically, SegWit will update the 1MB size block limit to 4-million unit block weight limit. This counts serialized
witness data and one unit and core block data as four units. This is an entirely new transaction format, meaning the block size is increased. SegWit counts each byte in a witness as 0.25 bytes towards the 1MB block limit, thus the maximum size of a block becomes just under 4MB.

It’s not that the data gets smaller, it’s just counted in a way that allows for the block limit to be increased.

The short/easy version

In simple words, signature related data is removed from bitcoin transactions, causing them to appear smaller in size. Also, making the block size smaller, further, allowing more transactions to take place.

 

Clearing up myths and rumors

Myth: SegWit as a soft fork is much more dangerous than a hard fork

A soft fork ensures that the backward and forward compatibility is under control. Also, when a soft fork is set up, old versions of Bitcoin software will be able to function without any faults. On the other hand, a hard fork requires every Bitcoin user to update to the new software to support the consensus rules. Any user that fails to upgrade to the new software might be under the risk of getting thrown off the Bitcoin network.

 

Myth: SegWit is more complicated than a super simple hard fork

Similar to a hard fork, SegWit proposes the same idea of increasing the block size limit. No doubt, it is pretty complex and introduces several changes, but it is a relatively simple conceptual change. Basically, SegWit ignores the signatures when calculating the transactions, but as a soft fork, some additional changes must be made to make SegWit transactions compatible with non-segwit nodes. These changes then have side effects which can be beneficial to Bitcoin. It also contains more functionality than a hard fork increasing the block size limit. The hard fork to increase the block size limit also appears simple, but additional changes need to be made to support the deployment and to solve the quadratic hashing issue with transactions.

 

Myth: Miners who don’t upgrade to segwit will be forcefully told to quit the bitcoin network

This is false since SegWit will be deployed using the BIP9 versionbits which uses a 95% threshold. A miner would not run into any trouble, as long as he follows certain rules. However, if he fails to follow these rules, he could end up with transactions including witnesses but he wouldn’t be having the witnesses nor the witness root hash in the Coinbase. This would be an invalid block that would be in the orphan pool.

 

What are the benefits of SegWit?

Besides the obvious benefit of having to increase the capacity, there are several other benefits that come with the introduction of SegWit. Some of those benefits are:

  • Node performance is tested based on how weighting data
  • Signature covers value
  • Linear scaling of sighash operations
  • MultiSig gets more security
  • Script versioning
  • Increased security to almost-full-nodes

Why hasn’t SegWit been activated yet?

If there is not enough support shown, it might result in a contentious fork. That means a part of the network switches to the new client while some remain to use the older version. This leads to two sets of cryptocurrencies with different rules, co-existing and competing for users and legitimacy.

In order to avoid such a situation, the developers of SegWit have programmed a specific rule in the software proclaiming that it will only activate once it reaches the 95% mark.

Currently, the support is hovering around 32-33%.

Factors behind the success of Bitcoin’s Value

Something, which facilitates the people in their lives, automatically will have some values. Whether it is in goods or in services. Therefore, Bitcoin’s uses and its benefits are the reason behind its value. Bitcoin community is active as other social networks. In addition, the main reason behind its increasing worth is the limited supply of bitcoins. Whereas, the government is unable to trace and tax. Bitcoins are in limited quantity. Accordingly,  the price of bitcoin in this year is 50x. which is seriously an insane swing of any currency.

Currency needs some qualities

There are some qualities which should be in any currency.  These qualities make the money more powerful.

Rare

Actually, money/currency should be limited in supply.  As economics proves that demand will increase with limited supply. Similarly, with the bitcoin, the total supply of 21 million coins increases its demand. In the result, its values increase day by day. Today’s value of bitcoin is $2251 as of May 23rd 2017.

Utility

The utility of any currency or object plays an important role in the determination of its value.  In the result, higher demand enhances the higher price.

Transferable

As currency/money always use in the transaction process, or in exchange meanings. Accordingly, If money has an ability of easily transferable then it will use by a large number of people. Moreo, if it has not, then money/currency’s demand will be low. Accordingly, Bitcoin’s transfer availability is in more than 100 financial sectors.

Unspecified

Everyone in the world has an authority to keeps his/her transactions private. Whereas, People like the process, which provides them such kind of privacy for their transactions. However, Bitcoin provides such type of process to its users.

Here is some discussion about how bitcoin value.

Scientifically

Bitcoin technology has worth for solving the long-standing two general problems. Clever solution for transactions of digital spending is achieved by the self-organizing and time-base record. The blockchain populate the bitcoin network, is well known public ledger.

Technologically

There is not central server to control or shut down the bitcoin protocol. Censorship resistance of bitcoin is critical. Clearly, means there is no one to control the usage of bitcoin. Censorship resistance to digital currency and its payment system makes the bitcoin an irreversible disruptive technology.

Social values

In the field of computer science, Satoshi Nakamoto’s innovations are milestones. Even so, with no limitation, bitcoin become the number one exchange and payment network. Each bitcoin users are responsible for his/her bitcoin’ security. Most of the people like the anonymous behavior of transactions are one the reason of bitcoin’s fame.

Bitcoin’s design

To the solution of double-spending, Bitcoin’s explicit design features offer users additional value:

  1. Bitcoin’s payment method
  2. Secure storage and transmission of user’s data
  3. Blockchain (decentralize public transaction ledger)
  4. Contract mechanism

 

Secure way for transactions

In addition, bitcoin user’s wallet generates the public keys.  Therefore, no one is allowing to step-in transaction’s process.

Network

Bitcoin is peer-to-peer decentralize network. However, nodes are distributing to decentralize the whole network. Whereas, Bitcoin is designed to seek the nodes. In short, the greater decentralization the healthier the network.

Above all are few aspects, that makes the bitcoin valuable. So, take time and make the decision with bitcoin world.

Guideline for Creating a Paper Bitcoin Wallet

A paper wallet is one the most popular and safest options to store your bitcoins. But before we go into the details paper wallet, we’d want you to know what is a Bitcoin wallet and why do you need one.

Bitcoin Wallet:

A Bitcoin wallet is a digital wallet that is used to store coins and make transactions; similar to a traditional bank account.

The wallet consists of two keys: A public key and a private key.

  • Public key: Your address on which other users send coins to you.
  • Private key: Which you use to send bitcoins to others. They key is kept private and only the owner of the wallet knows about it.

The combination of public and private key is what makes a bitcoin transaction possible.

It is important that no one knows about your private key , otherwise, it would give some unwanted entities the access to your wallet, which puts your coins at the risk of theft.

So, if you are using an online or an offline wallet, you’ll be vulnerable to hacking/malware attacks as your keystrokes can easily be logged.

Moreover, a stolen PC or losing your hard drive means you can wave bye to your digital assets for good.

Utilized with care, a paper wallet can shield you against these possibilities.

What is a Paper Wallet?

A paper wallet consists of the public and private keys that make up the wallet in a documented form.

It often has a QR code, so that you can quickly scan it and add the keys into a wallet to perform a transaction.

The prime benefit of having a paper wallet is that it doesn’t store the keys digitally; making it immune to cyber-attacks or a hardware failure.

A downside of the paper wallet is that it’s delicate and must be kept away fire and water.

How to Create a Paper Wallet:

  • Open your favorite browser and go to BitAddress.org
  • After typing some random characters to create randomness, you will be presented with a QR code, a private key, and a public key.
  • Click the tab “paper wallet”
  • Select the number of addresses to generate
  • Click “generate” button for creating new wallets
  • Once the wallet is generated, print it out to make a hard copy
  • Make a note of public addresses
  • Scan the QR code in your Bitcoin app to start depositing funds

What Are Some Security Tips for Paper Wallet?

Due to the fact that these wallets are used to save large amounts of money, it’s necessary to take precautions and make it as secure as possible.

The list of some useful tips for protecting your bitcoin wallet (paper) includes:

  • Make sure no one sees you while creating a wallet
  • BitAdress uses an algorithm named BIP38 to support encryption of private keys. The algorithm utilizes two-factor authentication i.e. something you have (paper wallet) and a passphrase.
  • Use a clean operating system such as Ubuntu to eliminate the risk of a spyware monitoring your activity.
  • Laminate your wallet or store it in a sealed plastic bag to protect it from water/damp.
  • Store it in a locker to protect it from theft.

Follow these tips and your paper wallet would be safer than ever.

To make sure your wallet is safer than ever, read our tips on how to secure a Bitcoin wallet.

Investors Are Worried After a Sudden Drop in Bitcoin Price

Want create site? Find Free WordPress Themes and plugins.

After a series of ups and downs, bitcoin’s price went to its top. However, it plunged to less than half of that value later. The unexpected changes are now compared to the dot-com bubble and are highlighting the speculative nature of investing in cryptocurrency. Investors are worried due to bitcoin investment

The price of bitcoin fell below $10,000 for the first, on December 1. At one point, it fell below $9,300 on one exchange. The price later rose back to almost $12,000, however, the investors and economists are still not sure how long the price will stay there. It is also said that the recent skim was due to the fear of crackdowns in the cryptocurrency markets.

South Korea has suggested a ban on the trading of cryptocurrency, although no plans are settled yet. Also, same news has been reported about China.

Bitcoin is a decentralized digital currency, as it is the largest and well-popular digital currency, that is globally bought and sold in exchanges.

According to Timothy Lee (senior reporter at Ars Technica), it is not based on dollars. The value of bitcoin floats against other cryptocurrencies, in the same way the euro and dollar glide against each other. Users say that bitcoin has got a very effective system for authenticating transactions, as it is based on a revolutionary technology.

Bitcoin users also point out that the currency is not tied to government’s whims anBitcoin Investmentd according to them, it’s a good thing. Recently the price dropped, and that may not be a good thing for those investors who are trying to figure out what crash actually means for the cryptocurrency’s future.

Recently many cryptocurrencies have shown the same swipes. According to David Kotok (Cumberland Advisors chairman and chief investment officer), almost 20 years ago, the technology and the new internet stocks accomplished valuation of $7 trillion, just because of speculation. The prices of shares used to be very high and after they collapsed, investors got badly miffed. And apparently, the same thing is going to happen with these cryptocurrencies.

Same rise and fall in the price of bitcoin was seen by the investors in December.  After China announced that it was banning all the banks that were trading cryptocurrencies, bitcoin fell by 40 percent just within days after hitting a record price of almost $1,150.

There’ve been dramatic ups and downs in cryptocurrency’s price last year. Bitcoin had the value around $900 at the beginning of 2017, however, its value got tripled within few months. According to Kotok, cryptocurrencies are highly speculative and investing money in cryptocurrencies is a speculative thing to do.  There’s a chance that you may make a profit, but Kotok has seen many people who invested their money into bitcoin and now they’re having loads of trouble in getting their cash back when they try to sell it.

According to some analysts, the cryptocurrency is trying to find an impermanent price floor, but according to a CNBC report, Citigroup analysts think that the price of bitcoin would plunge again to half of its current value. According to Ars Technica’s Lee, it’s still going to be unpredictable. She thinks it’ll go more up and then it’ll crash again. So, no one knows how far down it’ll decline.
