A renowned crypto exchange EtherDelta got its DNS server breached by an attacker on Wednesday, allowing the hacker to redirect millions of users to a malicious website.

The announcement of the hacking was made in a series of tweets where EtherDelta warned users that a hacker had temporarily hacked their DNS server and was redirecting users to a malicious version of the site.

Being a decentralized exchange, EtherData comes under the control of Smart Contracts, meaning that it doesn’t provide the third-party control of user funds. However, the exchange does allow users to import private keys to the exchange itself.

As a result of this attack, the hacker was able to steal private keys from users who unwittingly imported their private keys into the imposter website.

The data obtained has revealed that the hacker stole around 308 ether – worth around $250,000 at the time of writing.

EtherDelta said that clients who got to the exchange using either MetaMask or a hardware wallet are “totally sheltered” from the phishing attack. The organization included that funds from clients who never imported their key on the malicious site “should be safe,” but brokers might need to consider moving their assets to another wallet address as a safety effort — and reconsider their choice to import their private keys directly into a site.

The Risks Associated With Crypto Exchanges:

The attack came days after South Korean exchange Youbit revealed that it lost 17 percent of its assets as the aftereffect of a hack — the second the organization had faced this year — compelling its administrator, Yaipan, to declare bankruptcy.

Like Youbit, EtherDelta was a small exchange. CoinMarketCap reports that it processed just around $7 million of volume during the previous 24 hours, a figure that is, to some degree, lower-than-normal because of the breach. However, the exchange was well known among ERC20 token merchants, as it was one of the first exchanges to support tokens derived from lower profile ICOs (Initial Coin Offerings).

Neither of these hacks will prompt a huge disturbance in the worldwide digital currency markets, but each exhibits the risks related to using crypto exchanges.

Bitcoin in 2017

Want create site? Find Free WordPress Themes and plugins.

Bitcoin’s value increases with time. When bitcoin outperformed the U.S dollars by 30 percent. It became the best performing currency in 2017. Here, I’ll discuss some comparison with you, about the bitcoin profitability.

Gold, silver, litecoin, Altcoin vs Bitcoin

The 2017 year is best for bitcoin. This cryptocurrency achieves $5 bln market cap in early April. Gold is a precious metal with an extremely limited supply. Whereas, silver is a precious metal also limited in supply. The historic gold/silver ratio is 16:1, meaning 16 ounces of silver were equal to the 1 ounce of gold. The recent ratio of the gold/silver is 64:1, or 0.015625.

In 2013, Bitcoin price reaches to $1242 per coin. Unfortunately, on the same day, gold’s price was $1240. Whereas, litecoin reaches $48.47 per coin that time. In addition, silver’s price in late 2011, was $49.76 per ounce.

Bitcoin has an extremely limited supply and its mining is in digital form. Whereas, Litecoin is also limited in supply but not as bitcoin. The designed ratio of bitcoin/lite coin was, every 4 litecoin will equal to 1 bitcoin. The recent ratio of BTC/LTC is 80:1, or 0.01239. An abnormal difference of 20%.

Gold/BTC current ratios are similar. But their values cross each other. It is totally insane to compare gold/silver with bitcoin. The reason is, gold and silver have physical worth. Whereas, BTC/LTC both are the digital currencies.

Yes, we can compare BTC with other cryptocurrencies. Here, a question is, what is the future of bitcoin in 2017. Its answer is completely simple. Bitcoin’s future will be bright. Because it crosses the precious metal price.

Bitcoin vs Litecoin

Block time for bitcoin is 10 minutes. Whereas, litecoin’s block time is 2.5 minutes. The recent ratio of BTC/LTC is 80:1, or 0.01239.

There are a number of litecoins available in the market, i.e. 84 million. Whereas, bitcoins will not exceed the limit of 21million.

The other major difference between litecoin is the cheaper option for bitcoin miners while bitcoin mining procedure has some difficulties.

Bitcoin uses the longstanding SHA-256 algorithm, whereas litecoin uses the new algorithm known as Scrypt.

Bitcoin vs Altcoin, Ethereum

There are more than 500 cryptocurrencies. Few of them are known in financial markets, all over the world. 2017 is going well for cryptocurrencies. After the success of the Bitcoin, most of the digital currencies are active in the financial sector of the world.

Most of the altcoins are built upon the same framework. Which provide the cheapest ways of transactions on the internet. while ethereum gives developers the opportunity to create all sorts of applications that carry out their own set of operations.

Conclusion

Many other cryptocurrencies trying to target the bitcoin’s perceived limitations. Unfortunately, bitcoin has maintained its value. From above discussion, we conclude that, its golden chance to invest in the bitcoin world.

A History of Bitcoin Soft Forks and Hard Forks

Want create site? Find Free WordPress Themes and plugins.

Brief History of Bitcoin

Bitcoin was the first cryptocurrency, which was launched in 2009 by a mysterious developer, with a name “Satoshi Nakamoto.” Since the creation of Bitcoin, it has inspired thousands of other cryptocurrencies (generally called altcoins) and has gained an enormous acceptance across the world.

bitcoin blockchain

Though some altcoins have copied some aspects from the original concept of Satoshi, other altcoins also made significant development on the Bitcoin model. However, in some cases, some altcoins are just a copy of bitcoin and have the similar underlying program – but at the same time, they are a bit different from the original Bitcoin. In such cases, the bitcoin blockchain should undergo a procedure which is called “forking.”

Forking

  • In forking process, Bitcoin blockchain divided itself into two distinct entities.
  • Through forking, numerous cryptos with a similar name to Bitcoin were generated, including; bitcoin gold and bitcoin cash.
  • It may be a bit difficult for a casual investor to differentiate amid these cryptos and to plan the dissimilar hard forks on a timeline.

What is Genesis Block?

  • After Bitcoin was created, the first block was referred to as “Genesis Block.” It was mined on the Bitcoin blockchain by Satoshi.
  • Satoshi made many changes to the Bitcoin network in this process and those changes have now become even more complex as the userbase of Bitcoin has fully-fledged.
  • Not one can regulate when and how Bitcoin should upgrade, and this makes the entire process of changing/updating the system a little bit more complex.
  • Even after the creation of Genesis Block, a number of hard forks still existed.
  • Hard fork included the upgrading of software executing bitcoin and its mining processes.
  • Once a software is upgraded by a user, that software version discards all other transaction from older software and generates a new branch of the bitcoin blockchain.
  • However, users who use the older software are still going to continue to process transactions, henceforth, there’d be a similar set of transactions going on across two different Blockchains.

Bitcoin XT

  • This is one of the most notable Bitcoin hard forks.
  • In 2014, Mike Hearn made the software for integrating some of the new features that he proposed.
  • At that time, Bitcoin allowed only 7 transactions-per-second.
  • Bitcoin XT was intended to allow 24 transactions-per-second.
  • Bitcoin XT primarily experienced a great success after its launch, with almost 1,000 nodes running its software (back in 2015).
  • However, just after few months, users lost interest in Bitcoin XT, making it ‘doomed to die.’
  • Even though Bitcoin XT is officially available today, but it has visibly tumbled out of the errand of crypto community.

Bitcoin Classic

  • After Bitcoin XT failed, few cryptocurrency community members demanded an increase in the block sizes.

To accomplish this goal, Bitcoin Classic was created in 2016.

  • Unlike Bitcoin XT, Bitcoin Classic intended to raise block size to only 2 megabytes.
  • Just like Bitcoin XT, Bitcoin Classic also saw initial interest with almost 2,000 nodes for few months in 2016.
  • Bitcoin Classic still exists today and has gained a strong support from some developers.

SegWit

  • In 2015, Bitcoin core developer, Peter Wuille introduced the idea of SegWit (Segregated Witness).
  • SegWit aims to reduce the size of all Bitcoin transactions, letting more transactions to come off at the same time.
  • However, SegWit was officially a soft fork and might have assisted in prompting hard forks after it was initially proposed.

Bitcoin Cash

  • Some community users and developers decided to introduce a hard fork in response to SegWit, as well as to evade the procedure-updates.
  • This, at the same time led to the creation of Bitcoin Cash.
  • Bitcoin Cash detached from the main blockchain in August 2017 – when Bitcoin transactions were excluded by Bitcoin Cash wallets.
  • Up till now, Bitcoin Cash is the most effective and successful hard fork of Bitcoin.
  • Bitcoin Cash is also the 4th largest cryptocurrency by market cap and allows blocks of 8 megabytes.

Bitcoin Gold

  • After the creation of Bitcoin Cash, Bitcoin Gold was created.
  • The creators of Bitcoin Gold intended to evoke the mining functionality with elementary GPU (Graphics Processing Units) since they experienced that mining became also particular – in terms of hardware necessities.
  • Post-mine is an exclusive feature of the Bitcoin Gold and a procedure through which the developers mined 100,000 coins.
  • In general, Bitcoin Gold follows the basic concepts of Bitcoin.
  • Also, it is different in terms of ‘proof-of-work algorithm.’

As Bitcoin has been forked quite a few times within few years, there is a possibility that Bitcoin would still continuously experience both soft forks and hard forks in the future.

Samsung, which is best known for manufacturing electronics is taking blockchain platform in its consideration to track the shipments of its immense global supply chain network. According to this Samsung global news, it is considering an extensive implementation of a blockchain ledger platform so that it can track its shipments, globally.

blockchain and supply chain

Song Kwang-woo, who is the blockchain chief at the IT subsidiary of the Samsung, Samsung SDS, unveiled it while speaking to Bloomberg that a blockchain system could cut the shipping costs by 20%. Conspicuously, Kwang-woo also ensured that SDS is currently working on the development of blockchain platform for Samsung Electronics.

Involvement in Blockchain Technology

SDS has demonstrated its involvement in the implementation of blockchain technology for the shipping industry, effectively finishing a 7-month trial-project to track and record shipping logistics of both imports and exports in the vast shipping industry of Korea by the end of the year, 2017.

Related to the blockchain and supply chain collaboration, Kwang-woo also added:

“It will have an enormous impact on the supply chains of manufacturing industries. The blockchain is a core platform to fuel our digital transformation.”

SDS introduced a blockchain pilot for a shipping industry of Korea, in May 2017, so that it could keep an eye on the imports and exports of cargo shipments in real-time by leading an association, which included:

  • Korean Ministry of Oceans and Fisheries
  • Hyundai Merchant Marine
  • IBM, which is considered as a technology giant.
  • Korea Customs Service

 

Also known as a member of the EEA (Enterprise Ethereum Alliance), Samsung SDS successfully accomplished its first pilot-run of a shipment that perceived the whole procedure of a shipment, as well as delivery and booking, from Korea to China. As it’s also mentioned above, SDS settled its trial by the end of 2017 that eventually intended to handle all exports and imports in Korea via blockchain.

The metropolitan government of the capital city of South Korea, Seoul, chose Samsung SDS in November 2017, to develop a roadmap and organize blockchain technology to the whole administration of the city, as a method to advance transparency and boost citizen expediency. The government of Seoul has formally announced its purpose that by 2022, it would utilize blockchain technology across the whole municipal administration.
