Bitcoin Flaw Discovered: Inflation Attack Creates Bogus BTCs

Bitcoin Flaw Discovered: Inflation Attack Creates Bogus BTCs
The disclosure brings to question whether state-sponsored or organized hackers would have succeeded in exploiting the Bitcoin software bugs had they known about them to threaten what was thought to be an impregnable blockchain network. In a discovery that is likely to alarm mainstream folks, Bitcoin Core developers on Thursday said they've discovered - and fixed - software vulnerabilities in Bitcoin (BTC) that could have resulted in the minting of new but unauthorized bitcoins. An inflation attack would have flooded the cryptocurrency market with bogus BTCs but more importantly undermined the faith the world has placed in what is designed to be trustless digital gold. Members of the open source project announced on their website that vulnerabilities had been present since version 0.14 but they kept it a secret to prevent scammers from exploiting a technical loophole in double-spend transactions. (That seems like a centralized decision not unlike a central bank or government would make.) Version 0.15 is the updated version free of the software bugs. Bitcoin Core's developers discovered the bugs this past week and have since fixed it, according to bitcoincore.org. Along with the possibility of an inflation attack, the updated versions reduce or eliminate the possibility of denial of service (DoS) attack. The DoS flaw had the potential to disrupt the network by impairing some of Bitcoin's decentralized, blockchain-powered mining nodes. Members of the open source community, some of whom chose to stay anonymous, found the flaws and reported it to developers. Their explanations are highly technical but the implications are just as serious. "CVE-2018-17144, a fix for which was released on September 18th in Bitcoin Core versions 0.16.3 and 0.17.0rc4, includes both a Denial of Service component and a critical inflation vulnerability," per developers' statement on Sept. 20. "It was originally reported to several developers working on Bitcoin Core, as well as projects supporting other cryptocurrencies, including ABC and Unlimited on September 17th as a Denial of Service bug only, however we quickly determined that the issue was also an inflation vulnerability with the same root cause and fix." Many crypto investors view Bitcoin as the flagship coin of the $225 billion cryptocurrency market with BTC holding 51% market share. It's viewed as digital gold because of the immense computing power and electricity needed to mine new bitcoins as well as the promise that there will only be a maximum of 21 million bitcoins ever minted. The perception that Bitcoin is near-perfect in design is crucial for increasing adoption. An inflation attack that floods the market with millions of unauthorized bitcoins would be devastating. That's because BTC caters to libertarian-leaning individuals who have lost faith in central banks for devaluing sovereign currencies and who have lost faith in governments for mismanaging monetary systems. A successful hack would have undermined people's faith in Bitcoin with the likely result of a huge dip in valuation and investor confidence. Bitcoin's price rose to $6,700 over the weekend. Developers explained the double-spend vulnerability in Thursday's post. "If the output being double-spent was created in a previous block, an entry will still remain in the CCoin map with the DIRTY flag set and having been marked as spent, resulting in no such assertion. This could allow a miner to inflate the supply of Bitcoin as they would be then able to claim the value being spent twice."

Adam back: Bitcoins bullish trajectory isn’t over yet

Adam back: Bitcoins bullish trajectory isn’t over yet

Quick Take

1 minute read

  • Currently priced above $19,000 at the time of writing, bitcoin is on a trajectory that is very exciting. 
  • So passing numerous key resistance levels over the course of this year in the last few months, the leading cryptocurrency and its adoption rates are rising consistently. 

Currently priced above $19,000 at the time of writing, bitcoin is on a trajectory that is very exciting. Surpassing numerous key resistance levels over the course of this year in the last few months, the leading cryptocurrency and its adoption rates are rising consistently. Even making its way back into the news bitcoin has seen more than 140% in gains this year. 

Adam Back believes that the good times are yet to be over though as it will eventually fully succumb into a digital world.

Writing in a tweet earlier this week, the chief executive officer of Blockstream gave the opinion that bitcoin and its power as a form of digital gold can make it a game-changer in the future and the world of financial solutions.

This all came about when Adam was replying to a comment from the well-known crypto analyst Willy Woo who compared the spike in bitcoin to the relationship between early technologies and the successes that followed.

Bitcoin has been compared to digital gold on numerous occasions over the years. Many people see bitcoin though as a much more secure and faster option to the precious-metals as a credible store of value. Critics of the leading cryptocurrency would say differently however but many people have projected that the digital asset will soon overtake gold and become the dominant store of value asset in the future.

Raoul Pal expresses his bullish stance on bitcoin as he moves in on the industry

Raoul Pal expresses his bullish stance on bitcoin as he moves in on the industry

Quick take

1 minute read

  • The spike in the price of bitcoin over the past few months has been nothing short of incredible. 
  • Priced at $19,479 at the time of writing, bitcoin is well on its way to reaching its all-time high of $20,000 that it hit back in 2017 around the same time of year.

The spike in the price of bitcoin over the past few months has been nothing short of incredible. Priced at $19,479 at the time of writing, bitcoin is well on its way to reaching its all-time high of $20,000 that it hit back in 2017 around the same time of year.

Many people throughout the industry believe that the surge in the price of bitcoin has been triggered due to institutional money. 

Whereas the crypto industry has been spiking in price significantly over the past few weeks, the markets for the precious metal of gold has been seeing a huge outflow in recent times. Less than seven days ago, one analyst highlighted that gold so it’s the largest ever weekly outflow which is interesting because the timing means that it comes when prominent billionaire companies are indicating a bigger interest in bitcoin.

One long time investor in gold Raoul Pal, the chief executive officer of Real Vision and a veteran at Wall Street has recently started liquidating his positions in the precious-metals and put money into bitcoin and other digital assets.

Writing in a tweet earlier this week on the 30th of November, the veteran investor highlighted that he is dumping all of his holdings in gold and trading it in for bitcoin and ethereum.

Many more institutional investors are looking to the world of crypto in a more serious manner as the leading coin spikes to highs it hasn’t seen since 2017. Big institutions and conglomerates are also looking towards the asset and industry in a more proper and serious manner too.

   Of course, despite his excitement on bitcoin, Pal clearly wants to be a part of the shift that is occurring in the financial world as it moves more digitally. He has said:

“After all, it isn’t just a currency or even a store of value. It is an entire trusted, verified, secure financial and accounting system of digital value that can never be created outside of the cryptographic algorithm… It is nothing short of the future of our entire medium of exchange system, and of money itself and the platform on which it operates.”

Bitcoin Price Analysis: BTC Renewed Record Highs

Bitcoin Price Analysis: BTC Renewed Record Highs

This analysis brought to you by RoboForex

On Tuesday, December 1st, the Bitcoin price renewed its high at 19,731 USD. It has just corrected a bit and is now trading at 19,484 USD.

On D1, the BTC/USD pair renews the highs after a correction. The quotations rest near 100.0% Fibo. The aim of growth after a breakaway of this level and the upper border of the ascending channel is 20,800 USD. The MACD histogram is still above zero but declining gradually, which might mean that the pair will correct before growing on. The signal lines of the indicator have formed a Black Cross and keep growing, supporting further growth of the quotations. Both of these signals make a correction during the growth to the resistance level rather probable. The aim of the uptrend after the correction is 20,800 USD.

On H4, the perspectives of BTC/USD for further growth after the correction are also bright. The Stochastic keeps rising to the overbought area, promising further development of the ascending dynamics. However, a correction in the process is still probable. The aim of the pullback in our case might be the support at 18,200 USD. The aim of the growth after the correction is the same as on larger timeframes – 20,800 USD.

Well, rather symbolically, the BTC set new price records on the first day of winter. It renewed the high on the Binance and Bitstamp exchanges thanks to the agitation of individual investors. The media noted the interest towards the cryptocurrency, and the letter only increased.

One reason for such a “crazy” demand for the BTC might be the craving of investors for new mechanisms of saving their money. The cryptocurrency has grown noticeably compared to the lows of this March, and this is a weighty argument. On Twitter, the BTC rate is almost the hero of the day, the corresponding tag being the most clickable one.

Not only individuals push the BTC rate forward. The interest of institutional investors is also rather pronounced, sometimes even more crucial than the activity of individual users. Several opinion-makers from Wall Street have spoken in favor of the BTC, which attracted even more attention to the cryptocurrency.
