In the month of April 2018, 17 millionth Bitcoin was mined. But why this number is significant? Well, only four million tokens are left to mine. Bitcoin’s blockchain protocol is what makes Bitcoin mining a bit difficult, and the Bitcoin reward for mining a block also splits every 210,000 blocks. As seen, 12.5 BTC reward is received by the miners for unlocking a new block.

Mining of the Last Bitcoin

At this time, miners are deeply encouraged to mine so that they can get gradually more treasured Bitcoin tokens as a reward — before the supply reaches the capacity. However, when 21 million market cap is hit, there won’t be any Bitcoin rewards for miners. Though, transactions will be still required to get validated and stored on blocks, so that miners can profit from the transaction fees.

Segwit

  • Last year, the issue of scalability – block capacity – transaction costs showed up.
  • 1MB size limit for blocks was implemented by Nakamoto for halting miners making bigger blocks that were expected to be excluded from the network, as it could cause the blockchain to split.
  • At that time, the limit was big enough because of the small number of transactions. However, apprehensions that elevated were ultimately comprehended as Bitcoin advanced in popularity.
  • Ultimately, Bitcoin Core developers came up with a solution under the name “Segregated Witness,” which is more commonly known as SegWit.
  • Fundamentally, Segwit splits non-signature data from signature data of all transactions — significantly reduces transaction sizes that are stored on a block.
  • Moreover, it cancels out transaction flexibility by eliminating signatures from transaction data, paving the way for ‘Lightning Network’ incorporation.

Eventually, Segwit was implemented in August 2017, as a foremost stakeholder from the major Bitcoin mining pools and Bitcoin companies – for a solution to high transactions fees instigated by an accumulation due to the block size limits.

Core warning — the implementation of Segwit was possible because of the consent of the Bitcoin community. Even though there were huge concerns such as the inadequacies of Segwit2X, the community was divided up and the change was certainly not implemented.

  • Since August 2017, the implementation of Segwit has been slow across the global network. However, Bitfinex and Coinbase only presented the alteration in February 2018.
  • The launch matched with reducing the transaction fees – a testament to the envisioned outcome of Segwit incorporation.

Lightning Network

  • SegWit’s implementation laid the foundation for second layer solutions as well, in order to improve the network of Bitcoin.
  • The most projected one is the Lightning Network – it will do the same as the SegWit – though on a grander scale.
  • In terms of layman, the Lightning Network lets users excavate many payment channels amid themselves – off the Bitcoin blockchain.
  • The channel is going to be opened and recorded on the blockchain, though transactions will be made “off chain” till the payment channel is closed.
  • Basically, Bitcoin is deposited in this channel by users, so that they could make transactions by transferring potential of possession to each other.
  • When they plan to close the channel, users take their part of the total sum – the ownership of those sums is recorded on the blockchain.

This second layer solution matters a lot, as it will significantly upsurge the speed of transactions and the whole network. But if we talk about the future of bitcoin mining, this does stance few interesting questions for miners in the upcoming time. Once all 21 million Bitcoin have been mined – transaction fees would be the one and only incentive for miners. If the Lightning Network is completely integrated by that time, there’d be quite fewer transactions being recorded per-day. This could at the same time affect the amount of money that miners will be getting from transactions. Though, if we look 100 years from now, it is expected that all of these issues will have been solved by the wider crypto-community and Bitcoin Core developers.

A beginner’s guide to surviving a coin-split

guide to surviving a coin-split

 

We have all been hearing about the coin-split for a while now, so there are possible chances that it could happen any moment. While most miners are choosing to side with Bitcoin Unlimited and mine blocks larger than 1MB, some are sticking with the current Bitcoin asset aka, Bitcoin Tokens. This could lead to the network being split into two, aka “hard fork”.

Before the Split

First of all, be aware that this is a high-risk zone. Do not be holding onto more value in bitcoins than you are willing to lose. If you are planning on holding onto your bitcoins, then keep your private keys secure and under your control. Try investing in a hardware wallet, like TREZOR, Ledger Nano S etc. These will keep your private keys secure and provide you a backup PIN in case you ever tend to lose them.

Bitcoin guide

BE SURE TO MAKE A BACKUP OF YOUR PIN. 

You must not skip this step while installing any wallet.

We are not sure of when the fork would take place, but indications are that it could take place at any time and things could get messy from a scale of a few hours to maybe even days.

As such, our advice is that you don’t make any bitcoin transactions during that time period, at least not until we’re sure of what the post-fork situation looks like.

During the Split

There is no set date given as to when the “split” could take place, which means that a fork could happen at any time. However, if BU does fork, things would get complicated for a while. For eg, post-fork, transactions will look the same on either side. If a transaction is picked up by one end, there are chances that it’d be picked up on the opposite as well and may be valid for both chains. This is called a “replay attack” and unfortunately, BU does not include “replay protection.” Ultimately, spending coins on one end could lead to the same amount being spent on the other.

What you should do is, avoid sending any transactions until the post-fork situation is clear to everyone and you are sure that Bitcoin Unlimited is a winner.

After the Split

In the future, if both coins survive and you still have control of your private keys, you will have coins on both sides of the fork. But, it will be tricky to spend coins on one chain without unintentionally spending the same amount on the other end.

A solution for this would be to mine new bitcoin value after the split. If the coins are not present on either end, then no one can spend them.

Some exchanges might even set up coin-splitting services that will credit your account with BTC and BTU. Perhaps you might have to upgrade your wallet.

Also, if neither of these survives, your private keys will probably become worthless.

 

No one clearly knows what the post-fork scenario would appear to be, so as of now, we simply wait and see.

Hope for the best!

Cryptocurrency Security – Here’s All About Its Three Layers!

Want create site? Find Free WordPress Themes and plugins.

So, what’s a decentralized system? In simple words, we can say that a decentralized system works with no servers and each member is permissible to execute transactions. But in the case of the blockchain, each member must have to do some system-tasks as well, such as; storing transactional data.

cryptocurrency Security

Fork: Even a group of members can run an alternate-version of reality, which is called “fork.” The fork works by the similar regulations as the original decentralized system – though it might have a diverse state.

Let’s enlighten you about the hierarchical nature of cryptocurrency security!

First Layer – Tokens and Crypto Coins

  • One of the first and foremost thing in the crypto world is your cryptocurrency security.
  • Whenever you choose a cryptocurrency, you take all the perils and risks related to the protocol.
  • If someone can recognize and utilize protocol flaws, they can compromise the whole network, even including you; it won’t be much important which exchange/wallet you are using.

In the first layer, you can find two different types of currencies which include, the coins (Bitcoin, Ethereum, Bitcoin Cash etc.) and all ICO-issued tokens such as; MOBI or EOS.

What is the Difference?

Well, the difference is in the technical features. Each coin is either an independent network protocol or just a copy of some of it. When you research a crypto protocol from a security stance, make sure to find out if it can be centralized.

Let’s take an example!

In the case of Bitcoin, it’s now centralized around four major mining pools which also means that if all of them collaborate, they can possibly compromise the whole network.

Another advice! Whenever you look for proof-of-stake crypto, make sure to have a look at the genesis. This is also quite imperative, as whoever keeps the preliminary and initial stake can vote for transitions, as well as the network will be also trusting those who have higher stakes. If we take an example of NEO, a PoS network of China, which is same as Ethereum, was distributed 50/50 amid its ICO sales and developer community – unlike Ethereum distribution. Also, the NEO token distribution makes sure that no major stakeholder from the exchange platform or the developing side has enough stake to compromise the whole network.

Tokens

  • Now if we talk about tokens, all of them are based on a smart-contract aspect of few of the coins, which means their reliability and security is first based on the parent cryptocurrency – only subsequently on the smart contract’s code that issued it.
  • Mostly, all ICO coins (tokens) are based on Ethereum and just some of them are issued by smart contracts.
  • Also, it is imperative to point out that Ethereum got hacked a few years ago due to the DAO protocol hack – later hard forked and rolled back to the state. This also shows that the founders of Ethereum probably have a time machine as it looks like they have the ability to go back in time – yet again if it’s required.

Second Layer – Exchanges

One thing that everyone must understand about the exchanges is that they are written in custom-code with infrastructure security and has got nothing to do with blockchain. If we talk about an exchange, it is just a standard centralized web service arrayed in a data centre. That’s why whenever we talk about the exchanges, we always mention reliability and trust.

Almost every month we hear news about the data breaches and security events that occur because of exchanges.

Examples

Here are some latest examples!

  1. Back in December 2017, $63 million in cryptocurrency was stolen from NiceHash by hackers.
  2. At the beginning of this year, January 2018, more than $500 million in cryptocurrency was stolen from Coincheck by hackers.
  3. In February 2018, almost $195 million in cryptocurrency was stolen from BitGrail by hackers.

The hype around cryptocurrencies is due to the number of data breaches. Many exchanges have recently started their business – without investing in proper security measures. Simultaneously, if someone steals tokens/crypto coins from an exchange successfully, it’s nearly impossible to do anything about recovering it.

Third Layer – Wallets

Well, the third layer is linked to your personal security in the crypto world and you must’ve heard a lot about it before.

When you select a wallet for cryptocurrencies, you’ll have two options:

  1. Hot Wallet
  2. Cold Wallet

Hot wallet Vs Cold Wallet

  • The hot wallet is just like an account in exchange or in simple words, it is a website-based wallet.
  • In the case of a hot wallet, your tokens/coins are under the control of your wallet provider.

Whereas, a cold wallet can be a hardware, software or just a paper.

Bitcoin vs E-money – Everything you are looking for is here

Bitcoin vs E-money E-money

In earlier days, the concept of money used to be a physical substance, such as gold and silver. Some ancient cultures used living things as a form of money – cattle were one of the oldest forms of money.

However, the modern world is becoming more technology centered. Ever since the introduction of the internet, everything, from space to schools and shopping centers is dependent on the internet, and even online transactions have suddenly become a THING! More and more people are starting to make online trades, as it gives them the ease to purchase any desired item without having to leave the comfort of their bedroom.

Many of these purchases are often made with e-money or Bitcoin – the most widely used form of digital currency.

The currency first came into circulation in 2009. During that short time span, Bitcoin was able to spark a lot of attention and worldwide interest. As a result, many merchants are now starting to accept Bitcoin payments for their services.

However, despite all the talk about how people nowadays keep themselves updated with the latest technological innovations, many still seem to struggle when it comes to differentiating between Bitcoin and e-money.

In this article, we’ve outlined how E-money and Bitcoin are different from each other. Let us begin.

How are they different?

Electronic Money aka e-money and Bitcoin are two systems for making payments that are digital in nature. Besides that, nothing is common between the two.

Electronic money is a mechanism designed to interact with traditional currency such as Euros and Dollars. Whereas, Bitcoin is an independent cryptocurrency with its developers and users having complete control over it.

Some anonymous programmers using the pseudonym, Satoshi Nakamoto, launched Bitcoin in 2009. It’s a digital file that consists every transaction that has ever happened in the network in its ledger, aka, block chain.

Bitcoins are not like fiat money, they are mined using computer power of high-tech computers in a distributed global network of volunteer “miners”.

The money balance recorded electronically on a stored-value card is electronic money. Unlike Bitcoin, e-money is under the regulations and controlling of the Government central banking system. Banks and customers would have public-key encryption keys. Public-key encryption keys come in pairs. Only the owner knows the private key whereas the public key is available to everyone.

In comparison, Bitcoin is strictly limited to Internet connection but E-money just requires access to electronic devices like mobile phones and an agent network. Also, e-money is equal to the amount of fiat money in exchange for electronic form whereas, Bitcoin has no possibility of reaching the real world in the form of a bill.

Example of a system supporting E-money

M-PESA is a mobile phone money transfer system that had launched in Kenya in 2007. It starts with converting fiat money into an equal e-balance, by only entering the recipient’s mobile number and the transferred amount. The issuer confirms the transaction by sending an SMS to the recipient. The benefit of this method is to eliminate the interference of banks which makes it so popular and successful in Kenya.

Conclusion:

E-money and Bitcoin have their pros and cons but it is solely the responsibility of the user on how they handle their earnings. If more and more people shift from paper money to virtual currencies, this could irreversibly change our lives and social interactions.

Bitcoin – Investors sticking out the instability in digital currency

Want create site? Find Free WordPress Themes and plugins.

The value of the cryptocurrencies is fluctuating every moment. That is why investors still consider these cryptocurrencies are very new with supreme returns.

Ethereum’s value was all-time high over $400 in June but fell lower $200 for the first time since May 30. Furthermore, Bitcoin’s price correction wiped off closely $4billion in its market price.

Bobby Lee, CEO of the Bitcoin exchange told CNBC that the true value has yet to be discovered. He states in a Hong Kong conference, “If you think about it, the volatility is natural for an asset class that is so new. There’s no price discovery for it (yet).”

He explains that people need to discover the true value of the digital currency bitcoin. They have a tendency to trade these assets at a firm, promotional level before market analysis it could be worth more and this a time when the price jumps.

After getting legalized in several countries, the currencies have seen a significant rise in the popularity. Such as Japan legalized the bitcoins as a payment method.

Managing director of Hong Kong-based commodities and digital currency trading house Dave Chapman says, “We now sort of at … a tipping point, where people are now considering bitcoin or ethereum or digital assets as more mainstream.” And,” A lot of the people that we service are actually very comfortable with having 1 percent of their net worth into bitcoin as it is considered to be the best way to invest in bitcoin.”

He also adds, “There’s no other asset class in the world that could’ve given you the historic performance of this sector … the historic performance, which is obviously not representative of future earnings, … does appeal to a lot of people.”

For situation: $100 of Bitcoin credited in 2010 is now worth more than $75 million.

The analyst has made mixed estimations about these digital asset’s values and market cap as well. According to the BTCC’s Lee experience, the market cap for the Bitcoin will hit at least $trillion by 2025. He says, “I think it’s going to go to at least $1 trillion, if not maybe $10 trillion in the next five to ten years.”

Bitcoin’s current market cap is about $38.55 billion on supply and around 16 million in circulation. Whereas, the total supply of the bitcoin is 21 million. According to Lee, “In a grand of scheme of things, it’s nothing. Many, many companies are worth way more than that.”  Furthermore, tech companies already have their market cap in billions or trillions of dollars.

Regulations may help to increase the credibility of these digital assets. Accordingly, Japan, Russia, and China are introducing new regulations.

In the end, Chapman also added that a number of investors have a fear of loss. That’s why they are still not ready for bitcoin investment in the digital currency market.

“We get a lot of people who are like ‘You know what? I still don’t believe in this experiment. I’m not really a believer, but I’m tired of sitting on the sidelines and missing out.”
