The resolution of the Bitcoin Cash experiment – CoinGeek

The post originally appeared on Medium and we republished with permission from Unwriter.

Disclaimer: Before I go in, I want to say, if you are a Bitcoin application developer who happen to belong to any of the groups or organizations I am about to criticize here, I have nothing personal against you. I know all your hearts are in the right place. Its your group thats messed up, not you personally. Remember, you have choice. You can get out. I actually would like for you to read my post, step back, and think about why you are here. I would love to be on the same team as you, collaborating. What we have created so far with Bitcoin Cash is too precious to throw away. And this is why I speak.

From November 15 to 26 the Bitcoin Cash network went through its most important experiment since the inception of Bitcoin itself.

The so-called Bitcoin Hash War lasted about two weeks and moved in a direction that many people didnt expect Many people expected Bitcoin SV to make an aggressive re-org attack but that never happened. However what came out of the other side is the problem I will discuss in this post.

Bitcoin ABC was so afraid of an imaginary attack from SV that they made all kinds of mistakes, writing permanent code in rapid fire releases to the point where what they stand for is no longer recognizable.

And THIS ABCs self-inflicted scars that will forever exist immutably on the blockchain has led to a blockchain I can no longer build on.

I normally dislike writing because I would rather spend time building, and I prefer showing by doing, but at this time I realize I am in a very unique position of being the ONLY developer in the entire Bitcoin Cash ecosystem who has deliberately stayed politically unbiased, so I decided to contribute to the next phase.

Who is _unwriter?

First some background, heres who I am:

I work on two useful infrastructure projects in Bitcoin Cash ecosystem:

1. BitDB: Decentralized Database for Bitcoin https://bitdb.network

2. BitSocket: Realtime Message Bus for Bitcoin https://bitsocket.org

They power bitcoin applications such ascraft.cash,oyo.cash,trends.cash,matter,simple ledger protocol,memopay.xyz, and many more you probably have heard of at least once if youre a Bitcoin Cash user.

Next, about my identity. I proudly have exactly zero moral hazard. I have exactly zero conflict of interest. I am unaffiliated with ANY of the actors in the Bitcoin Cash ecosystem. There is exactly 0 person who knows who I am. Nobody has met me, nobody knows my voice, nobody funded me, I took donations from nobody, I have zero debts from anyone in the Bitcoin Cash ecosystem, both figuratively and literally.

I have only created what Bitcoin needed, and will continue to do so. There are some very exciting projects on the way I will soon release. And you will learn that BitDB, Bitquery, and Bitsocket have just been preludes to what Im actually trying to build.

Lastly, I am expressing myself here NOT as a follower, but as a chooser. I am choosing the blockchain I choose. I only pick the most superior blockchain because my projects deserve better.

Is this enough credibility for you? Or are you going to call me a shill and close this page? If you are a rational person, at least try to read till the end, because all I want is to collaborate with all of you and move forward in the right direction instead of fighting. And no matter which situation youre in, its not too late. You decide.

The importance of Capitalists in Bitcoin

I posted a public message to Bitcoin application developers last week:

The application developers are the capitalists of the nation of Bitcoin. And THEY are the ones who determine the wealth of the nation. Wise capitalists dont follow the herd. They notice opportunities and act on them.

I have been saying this that Bitcoin needs to attract application developers and the only way to do so is by signaling dedication to scalability, stability and openness instead of adding some new feature from the beginning. Below is an excerpt from an interview from back in July:

Note the last sentence in the excerpt:

they dont want to wake up one day to find that the rules of the game have changed overnight and all their effort has gone to waste.

And indeed, the rules of the game have changed in Bitcoin Cash. It is no longer the Bitcoin I signed up for.

Is Bitcoin Cash the real Bitcoin?

There is something very wrong with Bitcoin Cash ABC and its community today. There is too much misinformation out there, and people seem too willing to believe anything if it comes from some influencer guy who they see as respected by the community, even when they have no idea why they are respected by the community in the first place.

In this article I will explain what ABC has irreversibly turned itself into:

1. Censorable

2. Centralized

3. Unstable

4. Death of Permissionless Innovation

5. Anti Bitcoin Maximalist

I hope my perspective will be helpful for many application developers out there who are still confused about what they should do going forward.

Rid yourself from social obligations and social pressure. If your ideas are influenced by your employer, social clique, or by your past behaviors, try to be aware of this and think independently. You have choice. You can even leave your job and get a new one if you realize your employer doesnt stand for what you signed up for when you got into Bitcoin.

Just think about WHY you are here in the first place.

That said, what IS wrong with Bitcoin ABC?

1. Censorable

Heres a serious issue most ABC supporters seem to deliberately ignore out of cognitive dissonance, or because of misinformation.

Bitcoin Cash ABC has effectively become censorable. Yes, the very quality Bitcoin stands for censorship resistant money is dead on the ABC chain. you just cant see it yet.

The manner in which the centralized checkpointing was executed throughout the war should be a serious risk to any developer considering building on top of Bitcoin ABC.

This whole scheme of centralized checkpointing was powered by a cartel of crypto exchanges behind closed doors. This is not only immoral (in terms of Bitcoins morality), but potentially illegal AND makes the coin vulnerable even in the real world sense. And it is this real world aspect I would like to discuss, since this is a very real risk. Morality is subjective, but risk is real.

Heres a recorded livestream video where they explain, step by step, how this capture the ticker mission was accomplished by a cartel of ABC developers and crypto exchanges (instead of through Proof of Work):

Whats interesting about this centralized checkpoint is that it provides both the reason AND the means for a powerful adversary to take down the network in the future. They simply need to attack the associated ABC cartel, leveraging the centralized checkpoint to do whatever they want to the chain once compromised. And you wouldnt even know what went on as a user.

Of course I can already hear many people saying Shut up you shill, thats all just theory and is unlikely to happen!, but if you know anything about crypto or security, the rule of thumb is to be always paranoid than sorry, because crypto never forgets. And blockchain never forgets. A vulnerability once created never goes away.

Another rule is, where there is vulnerability there will be exploit. This is inevitable. Its just a matter of when. If you dont believe me, just ask Ethereum, their infamous DAO hack vulnerability had been known for a while but nobody thought it would actually happen for whatever reason.

Until it did.

Remember, if it can happen, it WILL happen, especially if its related to money and security.

Another lesson we can learn from Ethereums DAO hack is how the Ethereum team handled the hack afterwards.

Instead of moving on without messing with the economy, the core Ethereum team and the insiders decided to bail out the casualties of the hack, thereby saving some of the important early members of the Ethereum community.

This is why ETH and ETC (Ethereum Classic) split into two. ETC made up of people who believed in the principle, and ETH made up of people who have made a compromise. This demonstrated how a centralized protocol development team can play Keynes and roll back the ledger through powerful oligarchic actors conspiring with one another.

And this is where a lot of early Ethereum investors lost faith in the project.

It had turned into crony capitalism, as can be seen in the excerpt below:

I hope some of you are starting to see the parallels by now.

So, after all this, obviously I dont feel comfortable building my entire infrastructure empire on top of something that can be seized by various unknown gatekeeper adversaries without me even realizing whats going on.

Maybe not today, maybe not tomorrow, but if it can happen, it WILL happen, even if its after decades. Its just a matter of time. Thats NOT sound money. Its money with insecurities.

Ask yourself: Why would I want to build on something that can go down or be manipulated just like that one day? I am building something that will last forever, so this is already game over in my eyes.

2. Centralized

There are many aspects of centralization, but here I will only discuss the protocol development centralization which ABC has finally achieved through this war.

In the past you may have heard some anti bitcoin cash people criticize how Bitcoin Cash development is centralized. To be clear, this has never been the case, at least until this hash war. There were plenty of developers working on multiple implementations that follow the same Bitcoin Cash protocol, such as Bitcoin ABC, Bitcoin Unlimited, Bitcoin XT, Bitprim, Flowee, etc.

But today, while these multiple implementations still DO exist and may even look like they are doing fine, they will only exist as ghosts of their past.

As of today, no one can deny the reality that the only client that has the ultimate power in Bitcoin Cash is Bitcoin ABC. Everyone else has become decimated to the point where they simply function as a follower client. ABC doesnt even need to discuss anything with the other teams. They can simply add new features arbitrarily in a permission-less manner, and push it out.

You can see this in action with the last couple of releases where ABC has added adjustable checkpoint system (with a default of 10 blocks) WITHOUT even consulting any other developer team. You can watch the outrage over at Bitcoin Unlimited forum:

Theres an internal conflict going on there those who are too deep in the game with ABC that they fail to see the problem, and those who are calling them out but I dont think this will have any effect because these people have no influence under the new Bitcoin ABC puppet state regime.

3. Unstable

Bitcoin ABC is no longer sound money. There are so many things, but Ill just list out a few that make it a dealbreaker for me:

First, these various reactionary amendments written into the constitution of Bitcoin Cash in order to defend against some imaginary attacks from Bitcoin SV that may or may not have even existed should be a huge red flag. The war started last week with version 0.18.1, but after just a week its already at 0.18.5. And according to their development repository, theyve already finished 0.18.6 last week. So well probably see another release soon.

Second, these amendments have added needless technical debt and serious security vulnerabilities, which is why theyve been releasing patch after patch to fix the bugs they introduced with the patch before. The reckless rapid fire releases resulted in the network being split among multiple nodes, each with different versions of rules (Im only talking about ABC clients, imagine what this means for other clients like Bitcoin Unlimited who have to keep up with following these patches every day to stay in the game. And as far as I know, Bitcoin Unlimited was the only client that has even attempted to follow ABCs continuous delivery).

I think these follower node developers (Bitcoin Unlimited, etc.) may have some irrational hope that this power dynamic will change somehow in the future, but this time its different. Youve lost the moment you let ABC upgrade with a centralized checkpointing system and conspire with external actors to execute on their goal. You have not given power to ABC, but to external centralized actors.

Lastly, now with Bitcoin SV gone and no one to provide checks and balances, theyre happily adding all kinds of bells and whistles to Bitcoin. For example, here you see the code for Avalanche also known as the infamous Pre-consensus on their master branch.

I know many ABC supporters will say this is not really a big deal because its just being used for mempool synchronization, but you have no idea what kind of economic implication this will have. Economics is subtle, this is why classical and Austrian economists always say When in doubt, Laissez-faire. Things like this is whats called Keynesian and ABC is working very hard to achieve that status.

Unlike changing the block size limit, something like Avalanche changes the entire dynamic between the mempool and the blockchain, which is directly related to miners incentive, and one would be lying if he claimed to know exactly how this will turn out economically.

The first time Europeans brought gold from their foreign colonies they had no idea that would cause inflation. They just thought they would become rich. Obviously, you have more gold you become rich, right? And they did become rich, in the short term at least. But then inflation happened, and nobody knew what was going on.

Same with Bitcoin. Just because mempool becomes faster, doesnt mean youve succeeded. If the mempool synchronization becomes 1000 times faster but it completely messes up the economics of Bitcoin, its effectively a useless ledger. Congrats, you can now experience its uselessness 1000 times faster.

And dont forget, this is not something you can just complain about and it will go away. This Avalanche feature was the main reason why this entire hash war happened (also known as pre-consensus):

ABC cant give up on this feature because if they do, then it will be admitting they didnt know what they were doing. And that will mean they have lost everything for nothing. This is why they will very likely go ahead with this, and when this happens, one of the two scenarios will happen:

1. The community follows blindly so as not to rock the boat (Just like how the entire BTC camp is betting on Lightning and choosing to ignore all the red flags)

2. Some may DEFINITELY not like the change and decide to fork off again, therefore reversing adoption one more time (See the Bitcoin Unlimited forum for the early signs https://bitco.in/forum/threads/gold-collapsing-bitcoin-up.16/page-1301) But too late, ABC already has added all kinds of baggage and will have added even more by the time you realize you need to fork off.

Well, good luck to you, and I wish you the best with your coin, but either way its too unstable, and this is not Bitcoin.

And I only build on Bitcoin.

4. Death of Permissionless Innovation

One of the talking points of Bitcoin ABC camp has been Permissionless Innovation. Ironically, Bitcoin ABC is no longer a place for permissionless innovation either.

While everyone on team ABC seems to be very happy that they got the BCH ticker and proudly say the war was over even before it had started because of their coordination with the exchange cartel, they dont realize it is EXACTLY this point that makes Bitcoin ABC a deal breaker for any pragmatic application developer.

They have effectively turned themselves into crony capitalism blockchain.

What ABC has done by very successsfully pulling off this capture the ticker mission is they have demonstrated a textbook example of how a protocol developer can conspire with outside actors (a cartel of exchanges and centralized miners) to enforce centralized consensus, and do it so effectively that it even overrides the competition with a decentralized hash power. There exists no checks and balances, only the illusion of it.

This is pretty scary if you think about it. I know many people are afraid of centralization, but this is worse than centralization because it has the illusion of decentralization to the public yet it is centralized where no one can see it.

At least in centralized platforms they are completely transparent about their centralizedness, but crony capitalism looks just like capitalism to the outside world and crony decentralization looks just like decentralization to the outside world.

This means now you have to play politics and play nice with exchanges, miners, and the companies that control access to these actors such as Bitcoin.com, Bitmain, and Bitcoin ABC they are effectively the consensus makers.

It is exactly like the world you live in today, full of corruption. And Bitcoin was supposed to fix that.

I dont want to invest my time and resources working on a platform that can easily undermine my permissionless innovation anytime. For example, if you happen to build anything that competes with wormhole, expect it to get sidelined in various subtle ways, so subtle that you wont even realize it until it just hits you in the form of an ABC protocol update.

As an application developer, whatever you build can be overridden by this opaque cartel, just like how Twitter can always steer their open API to block their potential competitors from competing on equal terms on Twitter. (See Meerkat vs. Periscope)

And whats worse, the users will not even care that youre dead, they will witch hunt you and even try to silence you because they dont want to stir the pot and make the coin price go down. They will prefer the gatekeepers just win the war and carry on with no hiccup to the outside world. You can already see a glimpse of this in Reddit r/btc today.

Bitcoin Cash’s Q3 performance was horrid here’s what happened – The Next Web

Bitcoin Cash BCH is a household name in the cryptocurrency world. Its never far from being in the top five cryptocurrencies by market capitalization. But in the grand scheme of things, its not that old. Bitcoin Cash was created in August 2017.

In response to Bitcoins scalability challenges, its blockchain was hard forked to create a new coin, called Bitcoin Cash. Its creators wanted to create a cryptocurrency that acted as close to a digital version of cash as possible. It wanted to reduce the comparatively high transaction fees associated with Bitcoin to make everyday use of cryptocurrency a more achievable reality.

Bitcoin Cash tries to do this with larger block sizes, which means more transactions can be mined per block, in theory reducing confirmation times and increasing the speed of transactions.

However, this didnt last for that long. Further infighting and disagreements meant Bitcoin Cash itself forked in August 2018, resulting in two different blockchains. Bitcoin ABC (supported by Roger Ver and Bitmains Jihan Wu) and Bitcoin Satoshi Vision (from Craig Wright).

Based on the stance most cryptocurrency exchange desks took, Bitcoin ABC continued to be recognized as Bitcoin Cash. Bitcoin ABC/Cash continues to use the BCH price ticker while Bitcoin SV uses BSV.

As you might expect, given its close relationship to the OG cryptocurrency, BCHs market performance is never too far from Bitcoin. But lets take a look at how Bitcoin Cash has performed recently.

Bitcoin Cash first came to market in late 2017, just in time for the infamous bull run that lasted until February 2018.

As with most cryptocurrencies, Bitcoin Cash is yet to see the highs it saw in 2017 again, and has generally been on a downward trend ever since.

Bitcoin Cash had one up swing in trading price during April 2018, where its price shot up from $643 to $1,683 over the course of the month. A year later, at the end of April 2019, Bitcoin Cash was trading at around $293, a staggering 83-percent drop.

The cryptocurrencys performance for most of 2019 has been somewhat uneventful. On June 16, Bitcoin Cash reached its 2019 high, when it was trading at $487.

Bitcoin Cash had a positive end to Q2, but that trend didnt continue into Q3.

Across the first two weeks of July 2019, Bitcoin Cashs trading price dropped from around $403 on July 1, to around $283 on July 16.

In the context ofcryptocurrencyvolatility, this 30-percent drop is a somewhat minor price correction. Across the winter of 2017 to 2018,BitcoinCash saw its price tumble by over 75 percent.

After this market correction, Bitcoin Cash recovered enough to trade sideways for most of August.

On August 5, Bitcoin Cash reached a monthly high of $333, a notable 18-percent increase on the low it saw just a few weeks earlier.

However, that was as good as it would get for the digital coin in Q3. For the rest of the quarter Bitcoin Cash had a few price fluctuations, but it would close a long way down on where it opened.

At the end of August, another albeit minor price correction saw the cryptocurrencys price drop by 11 percent from $304 on August 27 to $270 on August 31.

Bitcoin Cash did manage to stave off the doom and gloom for a little while longer though. In the first three weeks of September a steady price rally saw the coins price rise from its end of August low to a monthly high of $322 on September 18.

Unfortunately, on September 19Bitcoin, Cashs price began to tumble as the coin witnessed another sizable market correction.

On September 26, Bitcoin Cash was trading at just over $216, a 33-percent drop on where it was trading just a week earlier.

Bitcoin Cash showed no signs of recovering in the final days of the quarter. On September 30, the coin was trading at $223, 45-percent down on where it opened Q3.

Perhaps the most notable news forBitcoinCash last quarter came in September, when it was announced thatBitcoin.com was looking to launch a derivative for the cryptocurrency.

The timing of this news actually coincided with the small rally Bitcoin Cash saw in September, however, it wasnt enough to encourage any kind of sustained growth.ABitcoinCash futures contract would be a long way off, and would need to overcome numerous regulatory hurdles before launching. Bakkt has done it for Bitcoin, so its not out the question that others will follow.

In early July, Scottish alternative punk-infused brewery Brewdog announced that it would be offering shares in its company, through its long-running equity for punks scheme, in exchange for cryptocurrency including Bitcoin Cash.

In the same week, Swiss fintech firm Amun AG announced a Bitcoin Cash exchange traded product, listed on the Switzerland-based stock exchange Six.

Neither of these announcements appear to have had any positive effect on the cryptocurrencys trading price in the short term.

Its been a shaky start to the last quarter of the year for Bitcoin Cash. for most of October it has been trading sideways with no notable price swings.

However, this weeks news thatcryptocurrencyminingmainstay Bitmain had fired one of its co-founders, who was also the largest stakeholder in the business, is likely to garner interest from Bitcoin Cash fans.

The announcement was made internally to Bitmain by the companys head Jihan Wu, a longtime supporter of Bitcoin Cash. In the hours following the news, Bitcoin Cashs price increased by 10 percent.

Indeed, while this might be good news in the short term for Bitcoin Cashs trading price, the long term impact remains uncertain.

Bitcoin Cash First Halving Countdown Begins, To Happen in May 2020 – Coinpedia

Bitcoin Cash(BCH) has been in the crypto market from August 2017, It was a result of Bitcoin Hard Fork. However, it is not widely accepted as Bitcoin or altcoins like ETH or XRP. Nowadays, the BCH network has come into notice again as its Halving news has resurfaced. Bitcoin Cash Halving is estimated to occur in May 2020.

It is the event where the number of generated Bitcoin Cash rewards per block will be divided by 2. The total number of Bitcoin Cash mined by miners per block will reduce from 12.5 to 6.25 BTC.

The Halving is about to occur in less than 160 days. The general estimation is that Bitcoin Cash prices will increase after halving as the amount of minted coins decreases. However, traders can expect volatility during this period while miners will earn lower mining rewards.

Director of BD at the Kraken exchange, Dan Hedl said that Bitcoin Cash Halvening will be catastrophic for Bcash. Also, the attack rate on BCH is estimated to increase by 51%.

That doesnt sound like a bad business model but as new mining machines enter the game, so the game gets harder. In other words, the halving could just make an existing problem worse. However, as a Hodler, the Halving would be deemed as beneficial.

Bitcoin Cash, NEO and XRP Price Prediction and Analysis for October 29th – NullTX

The cryptocurrency market exhibited some major upswings this week with the pricerising over 10% for most cryptos. Lets take a look at our select cryptocurrencies BCH, NEO and XRP and see what the charts have in store for us.

BCH/USD pair has turned out to be the third-best performing crypto with a bullish outlook. BCH is up by 6.8%, after having escalated from $253.20 to $271.54 that showed bullish sentiments over the intraday. Additionally, a bullish trend line has formed on the hourly chart that confirmed intense buying pressure. Thus, failure for the pairs price to dip below $254.57 critical support level signifies that the altcoin might continue higher. Looking at the technical, both moving averages are signaling a positive outcome since they are now below the price. The RSI is also trading above average that indicates increasing interest in buying.

An upside break above $274.81 resistance level may extend the bullish rally towards $285.00 level. However, if the price bounces back from $274.81 level, the bears might make an attempt to scale below $250.00.

Unlike BCH, NEO/USD pair has been trading on a range-bound between $13.00 and $10.85 levels with a bearish performance, which has reduced investors sentiments over the last 24hrs. The coin has succumbed to losses with a slight drop of about 2.4% after moving from $11.17 to $10.90, the current price. Afterward, the pairs price first saw an upside rally to a high of $13.65, but the bulls later reverse the trend and fluctuated the price momentum south ways. That showed strong selling pressure coming from sellers. Besides, the long-term SMA has managed to cross above the short-term SMA, and the RSI is heading south towards the oversold zone. This shows a high possibility for a further decline in the near term.

A downside break below the lower channel, which is support level could further extend losses towards $9.00 0r $8.5 level.

Like NEO, XRP/USD pair has also been on a tight range between $0.305 and $0.294. That confirmed a state of equilibrium between the buyers and sellers. Thus, XRP coin has shown no much of activity over the last 24hrs. Hence a strong breakout is expected in the near term. Despite the indecisiveness, the technical have indicated a bearish outlook, with both moving averages giving out a bearish crossover and the RSI trading below average. This shows that the bears are stronger than the bulls. However, if the bulls fight and push the RSI up to trade above average, they can prevent expected downside correction. Therefore, more buyers are needed in the market to recover some momentum.

A fall below $0.294 level may extend towards $0.100 level. However, if the price finds strong support near $0.294 and bounces back up to breach $0.305 level. Then a new uptrend can be seen with an imminent resistance level near $0.400.

Bitcoin Cash more vulnerable to timestamp manipulation than Bitcoin: BitMEX Research – AMBCrypto

Recently, BitMEX Research published a report detailing Bitcoins block timestamp protection rules, ones designed to stop nefarious miners from manipulating block timestamps and achieving unfairly high mining rewards. The report also discusses certain constants that were chosen and how those values could have particular implications for Bitcoin Cash.

According to the BitMEX research team, if too many miners join or leave the network, block times could become too fast or too slow, making the network unreliable. When a block is produced on Bitcoin, a timestamp is placed in the header by the miner and the actual time at which the block is produced is stored in the block itself.

If miners manipulated block timestamps, they could make it seem as if the difficulty needs to be adjusted to maintain the 10-minute rule for mining blocks, by either making it seem as if it took longer or shorter time to mine those blocks. To mitigate this risk, Bitcoin introduces two mechanisms to protect itself against this manipulation.

The first one, the Median Past Time Rule, states that the timestamp must be further forward than the median of the last eleven blocks. This median implies that even if six blocks are re-organized, time would still not move backwards. It is also consistent with the example provided in Meni Rosenfields 2012 paper, which shows that six confirmations are necessary to decrease the probability of success below 0.1% for an attacker with 10% of the network hashrate.

The other rule is the Future Block Time Rule, which essentially makes sure the timestamp cannot be set to more than a constant time ahead (2 hours), relative to the median time for the nodes peers. Further, another safeguard is that the maximum allowed gap between the time provided by the nodes and the local system clock is 90 minutes. However, unlike the MPT rule, this rule is not a full consensus rule as blocks with a timestamp too far ahead in the future are not invalidated, and can become valid as time moves forward.

Rule number one ensures that the blockchain continues to move forwards in time and rule number two ensures that the chain does not move too far forwards. These time protection rules are not perfect, for example miners could still move the timestamps forward by producing timestamps in the future, within a two week period, however the impact of this would be limited.

The report added that these rules have proven reasonably effective in preventing miners from manipulating Bitcoin timestamps. Bitcoin Cash however, is a different story. Since the Emergency Difficulty Adjustment model was replaced by a more simple rolling 24-hour system, though it is faster to resolve block time discrepancies, it is more susceptible to them than Bitcoin.

For Bitcoin, the 2-hour limit is only 0.6% of the 2 weeks it takes for a difficulty adjustment. On Bitcoin Cash however, the 2 hours become 8.3% of the 1 day it takes for a difficulty adjustment. According to the researchers, this appears to be potentially significant and if exploited, could result in changes to miner profitability.

Bitcoin Cash may therefore be somewhat vulnerable to miners manipulating timestamps, or at least more vulnerable than Bitcoin. On the other hand, although Bitcoin Cash may be more vulnerable to miner timestamp manipulation attacks than Bitcoin, any issues will be resolved faster.

Researchers also commended Satoshi Nakamoto for being able to think so far ahead 10 years ago, before anyone had any experience with building a blockchain.

Bitcoin Cash Retraces and Attempts to Retest the Previous High of $300 – Coin Idol

Nov 01, 2019 at 11:57 // Price

Bitcoin Cash Price Analysis: BCH breaks out of its consolidation and commences a bullish movement. BCH will resume its uptrend once the price breaks the previous high of $300.

Bitcoin Cash price Long-term forecast: Bullish

Recently, the Bitcoin Cash price has continued to make an impressive move in the direction of the previous highs. Presently, the market is facing resistance to a significant area of the price zone. In retrospect, the bears were on this critical price level on three occasions before the price zone was breached. Later sellers resumed as the price fell to a low of $200. Nonetheless, BCH has risen again to retest the previous highs.

However, Bitcoin Cash's continual rise will be determined if the previous high of $300 is violated. Two days ago, the coin has been making frantic efforts to violate the $300 previous high. The market will rise and reach the highs of $360 or $400 on the condition the bulls overcome the $300 price level. Nonetheless, BCH may be compelled to a sideways trend if the bulls fail to break the previous high of $300.

The horizontal channel was broken as the market continues its rise. The RSI levels 68 signal that price is in an uptrend. The EMAs have a bullish crossover as the blue line crosses over the red line indicating a price rise.

The coin is rising as the bulls continue to push the price to previous highs. All the daily indicators are signaling an upward movement in favor of Bitcoin Cash. The market will maintain its rise if the price pushes through the previous high of $300. Conversely, the coin will fall and trade below the $300 price level.

Key Supply Zones: $320, $360, $400

Key Demand zones: $200, $160, $120

The Crypto Daily Movers and Shakers -01/11/19 – Yahoo Finance

Bitcoin rose by just 0.01% on Thursday. Following a 2.78% slide from Wednesday, Bitcoin ended the day at $9,185.6.

In spite of a bearish week, Bitcoin ended the month of October with a 10.2% gain.

A bearish start to the day saw Bitcoin fall from a morning high $9,241.4 to a late morning intraday low $8,982.1.

Falling short of the major resistance levels, Bitcoin fell through the first major support level at $8,997.23.

Finding support from the broader market, Bitcoin bounced back to a mid-day intraday high $9,467.1.

Bitcoin broke through the first major resistance level at $9,409.13 before sliding back to $9,012 levels.

A late recovery to $9,100 levels left Bitcoin flat on the day.

For the bulls, the extended bullish trend remained intact in spite of failing to break out from the 38.2% FIB of $9,734. Bitcoin has continued to hold above the 62% FIB of 7,245.

Across the rest of the top 10 cryptos, it was a mixed day for the majors on Thursday.

Stellars Lumen and Litecoin joined Bitcoin in the green, with gains of 1.6% and 0.57% respectively.

It was red for the rest of the pack, with Bitcoin Cash SV (-4.27%), Bitcoin Cash ABC (-3.18%), and Trons TRX (-2.40%) leading the way down.

Binance Coin (-0.80%), Ethereum (-0.56%), EOS (-0.37%), and Ripples XRP (-0.11%) saw more modest losses.

Following Thursdays moves, Stellars Lumen retook the number 10 spot by market cap from Trons TRX.

There was nothing mixed about the month, however.

Bitcoin Cash SV (+47.42%), Trons TRX (+35.65%), Binance Coin (+25.52%), and Bitcoin Cash ABC (+25.11%) led the way in October.

Ripples XRP and EOS also made strong gains, with the pair ending the month up by 14.61% and by 9.75% respectively.

Stellars Lumen (+5.44%), Litecoin (+4.06%), and Ethereum (+0.64%) saw more modest gains.

Through the month, the total crypto market cap rose from a 24th October low $203.27 a 26th October high $257.76bn before easing back. At the time of writing, the total market cap stood at $245.17bn.

Bitcoins dominance held steady 67% levels at the month-end, while trading volumes jumped from sub-$50bn levels to $155bn levels before easing back to sub-$90bn levels.

At the time of writing, Bitcoin was down by 0.41% to $9,148.2. A bearish start to the day saw Bitcoin fall from an early morning high $9,186.6 to a low $9,111.0.

Bitcoin left the major support and resistance levels untested early on.

Elsewhere, Stellars Lumen and Trons TRX bucked the trend early on, with gains of 8.17% and 1.04% respectively.

It was red for the rest, however, with Bitcoin Cash SV (-1.64%) leading the way down.

Bitcoin would need to move through the morning high to $9,220 levels to support a run at the first major resistance level at $9,441.10.

Support from the broader market would be needed, however, for Bitcoin to break back through to $9,400 levels.

Barring a broad-based crypto rally later in the day, Bitcoin will likely fall short of $9,500 levels for a 3rd consecutive day.

Failure to move through to $9,220 levels could see Bitcoin fall for a 3rd day in the week.

A fall back through to sub-$9,100 levels would bring the first major support level at $8.956.1 into play.

Barring a crypto meltdown, however, Bitcoin should steer clear of sub-$8,900 support levels.

Anonymous Bitcoin Price Prediction Finally Poised to Fail – BeInCrypto

On January 21, 2019, an anonymous user made a series of future Bitcoin price predictions.

The user successfully called the December 2018 bottom. Also, the succeeding two predictions, which stated that the price will be $5300 and $9200 in April and July, respectively, were validated.

The third one, however, stated that the price will reach $16,000 in October. Since today is October 31, it is an interesting time to see if it is possible for this prediction to be validated.

Cryptocurrency trader @thecryptodog stated that a massive flow of cash will enter Bitcoin today, validating the prediction.

While the tweet seems sarcastic in nature, lets see if there is any chance, however slight, that it will be validated.

In order for the prediction to be validated, an increase of roughly 78 percent would be required.

During the past two years, the three dates with the highest daily rate of increase have been:

Even going further back, when the volume was significantly lower than what it is today and allowed for more volatile price movement, the highest daily rates of increase have been

While the 55 percent rate of increase in November 2017 comes close, all the other highest rates have been less than half of what is required to reach $16,000.

Considering that there are significant resistance areas above, and the movements are less volatile now than in 2013, it is probably safe to say that the prediction will be invalidated by tomorrow.

Bitwage Allows Companies in the EU, UK and US to Pay Wages in Bitcoin Cash – Inside Bitcoins

Last Updated on November 1, 2019

Bitwage, an international human resources and cryptocurrency payroll service provider announced that they will now provide Bitcoin Cash (BCH) as another payroll option. It will allow users in the EU, UK, and the US to convert a segment of their money into BCH. Employers also have the option to fully fund a payroll in BCH or offer it to freelancers or employees as well.

The company initially only provided payments in Bitcoin (BTC), before expanding towards the popular cryptocurrency of Ether (ETH). Shortly after adding the Ethereum blockchains namesake currency, Bitwage held a survey to see what its user base wanted going forward. They discovered a rather vocal demand for more forms of cryptocurrency to be added. Taking this to heart, Bitwage has now added Bitcoin Cash. BCH has held a consistent fourth place in the top digital assets. It offered low fees and fast transaction times that made it an obvious addition to Bitwages arsenal.

Jonathan Chester, Bitwages Chief Executive Officer, commented about the launch. He explained that cryptocurrency is becoming more and more mainstream by the day. Because of that, both freelancers and employees are searching for a way to diversify their cryptocurrency portfolio. He explained that Bitwage makes that process more comfortable. It allows people around the world to collect the cryptocurrency of their choice by means of a passive dollar-cost-averaging process.

Bitwages payroll process has been giving bitcoin deposits as early as 2014. It reportedly serves more than 30 000 that encapsulates independent contractors, freelancers, and employees. Theyve also managed to accrue about $1 million in funding from various investors like BPI France, Draper Associates, and Orange.

Bitwage claims on its website that the service has been made use of by employees at corporate giants like Facebook, Google, American Express, GE Comcast, and Airbnb. There are public institutions making use of it as well, with the World Health Organization given as an example. With BCH being launched, Bitwage revealed that it has now on-boarded Bitcoin.com.

Payment via cryptocurrency is a growing trend among those the tech-savvy niches of today. There is a genuine chance that it will become the norm in developed countries, with every major superpower already busy developing a national cryptocurrency. Bitcoin and its derivatives will be sanctioned as the so-called brand of cryptocurrencies in the foreseeable future. As the so-called altcoins start to play catchup with Bitcoin, it will be interesting to see how this pans out.

Ethereum developers have gone on record claiming that the Ethereum blockchain will be even more secure than Bitcoins due to its Proof-of-Stake system. The quicker Bitcoin stops being the biggest fish in the sea, the faster the crypto industry will grow.

Bitcoin and Altcoins Sighting Next Significant Break – Cryptonews

In the past few sessions, bitcoin mostly traded in a range above the USD 9,000 support levels. BTC/USD made a couple of attempts to start a fresh increase above the USD 9,300 and USD 9,400 resistance levels, but it failed to continue higher.

Likewise, many major altcoins struggled to resume uptrend and either corrected further lower or consolidated in a range, including ethereum, EOS, bitcoin cash, ripple, litecoin, binance coin, ADA, TRX, and EOS. ETH/USD is currently (09:00 UTC) holding the USD 180 and USD 178 support levels, but XRP/USD is declining towards the USD 0.290 and USD 0.288 support levels. Besides, XLM/USD gained traction today and rallied close to 10%.

Total market capitalization

There were range moves in, bitcoin price above the USD 9,000 support area. BTC/USD seems to be preparing for the next crucial move. If it breaks the USD 9,000 support, the stop could be near the USD 8,850 support. Any further losses may perhaps lead the price towards the USD 8,550 support.Conversely, the price could start a fresh upward move above the USD 9,250 and USD 9,350 resistance levels. The main resistance is near the USD 9,500, above which it could revisit the USD 10,000 resistance area in the coming days.

Ethereum price declined recently below the USD 185 support level. ETH/USD even traded below USD 180, but it recovered later. The price is currently consolidating above USD 180 and it seems like there could be more losses towards USD 174 or USD 172.To start a fresh increase, the price must surpass the USD 185 and USD 188 resistance levels. The next key resistances are near USD 195 and USD 200.

Bitcoin cash price topped near the USD 305 resistance area and it recently started a downside correction. BCH/USD traded below the USD 290 support and tested the USD 280 support. If there are more losses, the price could correct further towards the USD 268 and USD 265 support levels.EOS failed to stay above USD 3.300 and declined below USD 3.250. The price is currently holding the USD 3.200 support. If there are additional weakness, the price could test the USD 3.050 and USD 3.000 support levels in the near term. On the upside, there are resistances near USD 3.350 and USD 3.400.XRP price failed to climb above the USD 0.300 and USD 0.304 resistances on many occasions. As a result, XRP/USD started a downward move below the USD 0.295 and USD 0.292 supports. The price is now trading near USD 0.290 and it could decline towards the USD 0.285 support.

In the past three sessions, a few small capitalization altcoins climbed higher and gained more than 5%, including TT, LAMB, ZIL, DCR, CENNZ, IOST, XLM and STEEM. Out of these, TT rallied close to 50% and LAMB jumped around 28%.

Overall, bitcoin price is testing an important support area near USD 9,000. It is likely to start another increase as long as it is above USD 9,000 and USD 8,850. If not, BTC/USD could revisit the USD 8,550 support area._____

How Microsofts censorship of GitHub will affect Bitcoin – Decrypt

Software hosting platform Github yesterday took down the APK of a protest organization app utilized by the Tsunami Democrtica group advocating Catalonian independencefollowing a court request.

This marks another time that GitHubwhich was acquired by Microsoft in June, 2018has censored its platform, after it suddenly blocked developers in Iran, Syria and Crimea from using its services. But theres a wider issue here for the entire cryptocurrency ecosystem. Github is a repository for almost every piece of code in the cryptocurrency sector. And some developers think this is such a worrying problem that it is only a matter of time before the Bitcoin repository will have to be moved.

"It only took a few months for Microsoft to destroy GitHub culture and openness. Such a shame," Andreas Antonopoulos, author of Mastering Bitcoin, tweeted.

Antonopoulos pointed out that the underlying protocol, known as git is decentralized, which means Microsoft cant stop it with the press of a button. But, what he described as the collaboration platform is still on GitHubthe place where everyone discusses what pieces of code should be implemented and requests to add new code are made. And if this were to happen, it would be a nuisance. Wouldn't be surprised if GitHub de-platformed Bitcoin devs at some point, he added.

In response, a GitHub spokesperson told Decrypt that compliance with government officials was sometimes mandatory to ensure operational integrity within a given territory. He said, Although we may not always agree with those laws, we may need to block content if we receive a valid request from a government official, so that our users in that jurisdiction may continue to have access to GitHub to collaborate and build software."

Be the first to get Decrypt Members. A new type of account built on blockchain.

But this hasnt come as a surprise to Bitcoin developers. Wladimir van der Laan tweeted back in June, 2018, that the Bitcoin repository should move because of Microsofts acquisition. However, he added, No real hurry, but I expect this is the beginning of a long painful road of [GitHub] toward [obsolescence], possibly ending the same way as codeplex did. (Codeplex being a code sharing platform that Microsoft shut down in 2017)

But if the Bitcoin repository on GitHub should move, where should it go?

One option is GitHubs main competitor, GitLab. Its an open source project and has tools for self-hosting repositories, enabling teams to keep full control over their own projects.

Some cryptocurrencies have already moved over. Last year, Sia cryptocurrency migrated over to GitLab and hasnt looked back since.

GitHub has become something of a backbone for open source projects over the past few years. This is ironic, as GitHub itself is closed source and centralized, David Vorick, CEO of Sia, said, in a blog post at the time. GitLab on the other hand has aligned themselves much more with the true open source philosophy.

Alternatively, there is a version of the Bitcoin repository available on Tor, maintained by van der Laan himself. Tor is a network for anonymous communication, accessed via the Tor browser.

Other developers are experimenting with peer-to-peer technology to fill the void beginning to open in the light of Githubs recent moves. Developers have built platforms like Radicle, which offers peer-to-peer code communication but is still in beta mode.

GitHubs actions serve as a warning to those building decentralized platforms, that they should stay wary, to prevent elements of centralization from seeping through. On Tuesday, the founder and inventor of the World Wide Web, Sir Tim Berners Lee, reminded us that, since it started, the first Internet has been constantly subverted and that its time to fight for the web we want. The time is now.

Space Travel: Redefining the Travel Customer Journey With Virgin Galactic – Hotel-Online.com

Pier-Luca Rapin | October 31, 2019

By Pier-Luca Rapin

It is another level of personalization, it is not only to be sure to have the right water and the right pillow in the room, this is understanding why people are actually going in that journey, helping them realize that dream and being able to live that little moment the best as they can Martijn Brouwer, General Manager Astronaut Relations, Virgin Galactic

During the 2019 Young Hoteliers Summit, EHL Lausanne took a one-way ticket for space with the visit of Martijn Brouwer, General Manager Astronaut Relations and hospitality at Virgin Galactic. Virgin, as a group, has always been defined by a strong service philosophy. Nevertheless, Virgin Galactic is taking this philosophy a step further.

The offer of space travels has to come with a perfect customer journey and must be an experience as a whole. The person in charge of the customer experience is Martijn Brouwer, a 20-year veteran of the Virgin Group. During his career, he had the opportunity to work with Richard Bransons family on their Caribbean island, allowing him to discover the Virgin Hospitality spirit first-hand. Admittedly, he said: I dont have the deep love for space our pilots have, but definitely an interest into bringing hospitality into this field.

So what are the possibilities for hoteliers? How can a heavily scientific operation endeavor turn into a world-class experience with high standard relations? How can they deliver a unique hospitality experience to their guests? Fasten your seatbelts, and be ready to reach Mach 3 through the Virgin Galactic experience.

In the near future, well have a base on the moon, or there will be some form of hospitality in space.

The experience at Virgin Galactics base in New Mexico will start six months before takeoff. Customers will begin their transformation process which involves physical and psychological preparation, building the tailor-made hardware, suit, communication gear and all the equipment necessary for a round-trip to space. Customers go from being on a waiting list to being labelled future astronauts, but it is only the beginning.

Four days before the actual flight, future astronauts will arrive in New-Mexico, experience a three-day preparation program and on the 4th day, they officially become astronauts by breaking Mach 3, breaching the atmosphere and reaching space at an altitude of 100km. The whole Virgin team uses this long preparation process to determine the motivations behind each customers aspiration to fly is with Virgin Galactic and what they want to get out of this flight. This is Virgin Galactics gravity point, which informs and enhances the entire experience.

Build your Service Culture: Learn more about EHL Advisory Services

Shifting from scientific operations to a world-class experience is a stringent process that has been taking place over many years at Virgin Galactic and it is no easy feat. It involves a complete culture shift of companies to provide the best possible journey for their customers.

Virgin Galactic aspires to make their team understand the key fragments of customer relations and what guests are going through when they choose to experience a space flight. But customer-centricity is not a given, some scientific teams will either not relate or not see an incentive to evolve a hospitality mindset.

The highest stakes lie with the employees who are involved in guest relations and are in direct contact with them, no matter the stage of the journey or the nature of the interaction. They are a group of people who makes a dream come true by delivering a high-standard service. They need to tailor the experience as a whole. This is only possible if they have a better understanding of how to produce the right service for the right client, they focus on why future astronauts want to go to space and what guests want to take back from this experience. At each touch point, it is a highly personal, individualized and empathetic process.

Virgin Galactic need to bring the level of personalization a step further,

It is not only to be sure to have the right water and the right pillow in the room said Brouwer, they help their guests to realize the dream and strive to make them live this relatively short voyage to the fullest.

This is only made possible through a deep understanding of the client, by each employee. Breaking the barriers down is the way to do so. People are much more open to learn and listen to an employee if he is more than just a worker on-site. They need to mentor customers through their experience. Guests need to be coached to enjoy such an unknown and stressful experience, and employees need to be aware of this reality. People working in space hospitality will have much more responsibilities than traditional hospitality workers, they enter the intimacy of the future astronauts and provide an unparalleled service.

All the experience you live during your flight are things people havent been through before, so they need to be coached to enjoy these moments.

Virgin Galactic understands that involving customers friends and family constitutes an important part in the experience. Richard Bransons company ensures that the future astronauts loved ones are closely involved in a way enhances the experience and provides support throughout the duration of the trip.

They are so closely involved that the future astronaut feels their support all the way, and dont have to go back in the evening and relate the story of the day, they are there, and they can support each other.

This includes looking after them during moments where they cant be with the future astronaut, by taking them out, connecting them to the other families, involving kids in the experience and making it is an enriching experience for all. Bringing this dimension into the process allows the customer to focus on his experience and allows him to feel the support of people close to him.

The space hospitality industry is a very niche and yet-to-be-defined field, but there are existing opportunities for hoteliers. Professionals: keep your eyes open! The space tourism industry faces the same kind of difficulties hotels do. For example, talent acquisition, demographic conditions, regulations, profitability and turnover. Moreover, space companies need to find the right product for the right client, at the right moment as well as the right people to work with. This emerging industry will be a sandbox for new hospitality concepts and set new standards for the industry as a whole. These changes bring new solutions to hospitality problems and are a source of inspiration. Providing a fully tailor-made experience is an example for our hotels and must be taken into consideration. It represents a development of the industry that hoteliers can bet on. Takeoff is imminent: hoteliers, dont forget to book your tickets.

Radiation Experiment, Cookie Oven and More Headed to Space Station on Cygnus Cargo Ship – Space.com

An Antares rocket is set to launch a bevy of crew supplies and scientific cargo to the International Space Station this upcoming weekend (Nov. 2) from NASA's Wallops Flight Facility in Virginia.

Perched atop the rocket will be a Northrop Grumman Cygnus cargo spacecraft, and tucked inside will be approximately 8,200 lbs. (3,700 kilograms) of supplies and hardware. The craft will ferry supplies to support the crew on the space station as well as a variety of experiments and research equipment. These will support investigations in topics ranging from radiation mitigation to rover control to materials recycling.

One of the dangers of deep-space travel comes in the exposure to damaging radiation. Unpredictable space weather, in particular solar-particle events such as coronal mass ejections (or CMEs), can expose astronauts to enough radiation to potentially cause long-term adverse health effects. One experiment aboard the Cygnus, the AstroRad Vest, aims to help NASA mitigate those damaging effects.

The AstroRad vest is a garment designed to help shield astronauts from radiation while traveling in space. It is made out of HDPE (high-density polyethylene) and will be tested by the crew currently onboard the space station. Although the vest is designed for use farther out into space, the space station is the perfect environment to test whether astronauts wearing the AstroRad garment will be comfortable and able to carry out their daily activities in space. Astronauts will record data on how easy the vest is to put on and how it fits, as well as the range of motion it allows.

Made In Space, a California-based company that specializes in off-world manufacturing, is also sending up an experiment that will test a new facet to their 3D printing abilities: recycling. The company that pioneered 3D printing in space will now attempt to recycle the plastic materials it prints by breaking them back down into polymers to be made into plastic filaments that can be used again. This will enable more tools to be printed without having to rely on material resupply shipments from Earth.

"The recycler is a facility that will break everything down and turn the used polymers back into feedstock," Michael Snyder, chief engineer at Made In Space, explained during a prelaunch science briefing on Oct. 17. "This way, we don't have to continually launch polymer and filament."

Snyder added that the company plans to analyze samples printed in space after these materials return to Earth, where they can be compared to samples printed on the ground.

ESA astronaut Luca Parmitano will control this rover remotely in November to simulate remote control of future lunar rovers. In the experiment, known as ANALOG-1, he will use the rover and its arm to move rocks instead of cones.

When astronauts land on the moon or Mars, they might be accompanied or preceded by robotic companions sent to help look for resources, build potential habitats and much more. Analog-1, an investigation spearheaded by the European Space Agency that is headed to the space station with this launch, will explore how humans can best operate and communicate with robots off world.

Astronauts onboard the space station, will investigate how well they can remotely by control a rover back on Earth. During this investigation, astronaut Luca Parmitano will maneuver a robotic arm to select, collect and store geologic samples with the help of communication with an Earth-based team. He will also navigate the rover along a specific path.

NASA added during the teleconference that this research will benefit the upcoming Artemis program and the Lunar Gateway, as astronauts will likely be controlling rovers on the lunar surface while in orbit around the moon.

Also onboard Cygnus will be the Zero-G Oven, which astronauts will use to bake cookies in space for the first time. Who doesn't enjoy the aroma of fresh-baked cookies? On future long-duration space missions, such fresh-baked food could have psychological and physiological benefits for crewmembers, enabling them to prepare more-nutritious meals. In testing this oven, astronauts will examine heat-transfer properties and the process of baking food in microgravity. The device has a specially designed toaster-like shape with a top temperature of 685 degrees Fahrenheit (363.3 degrees Celsius).

The upcoming flight is the first within the second phase of Northrop Grumman's contract with NASA for commercial-cargo delivery services. The Cygnus spacecraft is utilizing some shiny new upgrades it received prior to the last launch, including the ability to accommodate late-load payloads. This means the craft will be able to carry life sciences payloads, including a crew of rodents, to the space station.

The Rodent Research-14 experiment, an investigation into how microgravity disrupts the body's 12-hour circatidal clock, will explore how disruptions to daily light cycles affect human cells and organs by studying changes in rats. (Rats are one example of a model organism a non-human species that are used to help understand biological processes in our own species). During the pre-launch briefing, researchers explained that genes associated with 12-hour light and dark phases, or the 12-hour molecular clock, are also associated with the most common form of human liver disease, which contributes to insulin resistance and diabetes.

Understanding the 12-hour clock's role in influencing liver function could have major implications for maintaining human health. Researchers are hopeful, it was noted in the teleconference, that the results from this study could provide insights into liver disease and could lead to new treatments.

(Image credit: NASA)

Cygnus will also carry equipment that will support an experiment already onboard the space station: the Alpha Magnetic Spectrometer - 02 (AMS-02), a scientific instrument affixed to the station's exterior that's designed to look for evidence of dark matter.

Roughly 15% of the universe is made up of "ordinary matter," or material we can see, while the rest consists of a mysterious substance called dark matter. Scientists cannot directly observe this enigmatic material, as it does not emit light or energy.

In 2011, the AMS-02 launched aboard the space shuttle Endeavour to scan the cosmos in search of dark matter. Three of the instrument's four cooling pumps have failed over the years, but because the aging instrument has served the scientific community so well, NASA wants to repair the AMS-02. The agency plans to conduct some on-orbit repairs through a series of spacewalks during which astronauts will cut and reconnect fluid lines in space for the first time.

During Thursday's briefing, researchers said that the planned repairs could give the valuable instrument as many as 10 more years of functionality.

Israeli radiation protection vest to blast off to Int’l Space Station – The Jerusalem Post

StemRad CEO Dr. Oren Milstein (L) and Israel Space Agency director-general Avi Blasberger with the AstroRad radiation protection vest. (photo credit: STEMRAD)

A radiation protection vest developed by Tel Aviv company StemRad will depart for the International Space Station (ISS) on Saturday, on-board a robotic resupply spacecraft launched from NASA's Wallops Flight Facility in Virginia.

StemRad is behind the AstroRad vest, offering personal protective equipment for astronauts to wear beyond low Earth orbit, mitigating space radiation exposure outside the Earths magnetosphere.

The AstroRad vest will undergo a series of tests and ergonomic experiments on the ISS, orbiting 400 kilometers above Earth, ensuring that the equipment is ready for operational use. The company's adapted vest for women, who are particularly vulnerable to space radiation, will be tested by three female American astronauts in micro-gravity for variable durations and during routine activities.

Under an agreement between the ISA, NASA and German Aerospace Center (DLR), the research represents an important step ahead of launching the AstroRad radiation protection vest aboard NASAs unpiloted Artemis-1 mission around the Moon in late 2020 or early 2021, the last test flight before NASA begins manned deep space missions.

"The success of the AstroRad trials will constitute a critical contribution from the State of Israel to NASA's most ambitious research program since landing on the moon," said StemRad CEO Dr. Oren Milstein.

"Thanks to the collaboration between a number of professional and governmental bodies, led by Lockheed Martin and the Israel Space Agency, we are very close to a proud achievement for our space industry and the entire State of Israel."

Bringing the Israeli flag to the ISS for the first time, the AstroRad uses a proprietary smart shielding design to selectively protect organs and tissues which are most sensitive to radiation exposure.

Should the tests prove successful, AstroRad could be a critical part of NASAs space exploration plans for years to come, including the establishment of a sustainable human presence on the Moon and later sending astronauts to Mars.

According to StemRad, the results of experiments conducted on the ISS, together with data obtained during the Artemis-1 mission, will provide NASA will all the information necessary to evaluate the vests as an effective and essential tool for protecting astronauts from deadly radiation in deep space missions.

All human space exploration missions to date, except for the Apollo moon landings, have been restricted to low Earth orbit (within 1,200 miles of the Earth's surface), where the Earth's magnetic field protects astronauts from most space radiation threats, including deadly solar storms and galactic cosmic rays.

"We are breaking Israeli records of activity, creativity and initiative in all areas of science, and in space in particular," said Science and Technology Minister Ofir Akunis. "I am proud of the developers of the first Israeli space suit."

Also aboard the spacecraft will be the Zero G Kitchen Space Oven, designed by Jewish couple Ian and Jordana Fichtenbaum from New York. The oven is an insulated container designed to hold and bake food samples in the micro-gravity environment of the ISS.

Their prototype oven together with a batch of cookie dough from DoubleTree by Hilton will enable food to be baked in orbit for the very first time. Built in collaboration with NanoRacks, a provider of commercial access to space, the couple aims to make space travel more comfortable for astronauts spending months on-board the ISS.

Since convection heat transfer is difficult or impossible in zero gravity, the oven relies on electric heating elements similar to that found in a toaster oven. The device is powered by electricity drawn from the ISSs internal power system.

The oven can be adapted to provide grilling, pan cook and griddle modes of cooking, all in a micro-gravity environment.

How the Big Bang may have happened decoded – Economic Times

WASHINGTON: The universe began with the Big Bang, and now scientists have explained how the mysterious explosion may have taken place around 13.8 billion years ago.

The Big Bang theory states that all matter that exists today in the universe sprung forth from a single point in an epic explosion.

The research, published in the journal Science, details the mechanisms that could cause the explosion, which is key for the models that scientists use to understand the origin of the universe.

"We defined the critical criteria where we can drive a flame to self-generate its own turbulence, spontaneously accelerate, and transition into detonation," said Kareem Ahmed, an assistant professor at the University of Central Florida in the US.

"We are using the turbulence to enhance the mixing of the reactions to the point where it transitions into this violent reaction and essentially leads to supernovas, which is exploding stars in simple terms," Ahmed, co-author of the study, wrote in the journal.

"We are taking a simplified flame to where it's reacting at five times the speed of sound," he explained.

The team uncovered the criteria for creating a Big Bang-type explosion while exploring methods for hypersonic jet propulsion.

"We explore these supersonic reactions for propulsion, and as a result of that, we came across this mechanism that looked very interesting," said Ahmad.

"When we started to dig deeper, we realised that this is relatable to something as profound as the origin of the universe," he said in statement.

The key is applying the right amount of turbulence and mixing to an unconfined flame until it becomes self-perpetuating, at which point the flame begins to burn the ingested energy leading to a hypersonic -- exceeding the speed of sound -- supernova explosion.

The finding may have applications in faster air and space travel, and improved power generation, including reactions that generate zero emissions as all of the products used in the combustion are converted into energy, the researchers said.

The discovery was made by using a unique turbulent shock tube that allowed explosions to be created and analysed in a contained environment, they said.

The researchers noted that ultra-high-speed lasers and cameras were used to measure the explosions and help indicate what factors were needed to reach the point where a flame becomes a hypersonic, violent reaction.

DC-X: The NASA rocket that inspired SpaceX and Blue Origin – Astronomy Magazine

Until that time, no spacecraft could lift off with built-in rockets and then land vertically. The new rocket was testing never-before-seen technologies for spacecraft, and engineers saw it as an exciting project to be involved with.

I look back on that time in my career, and I really appreciate it, says Dan Dumbacher, the eventual project manager for the DC-X program. We were doing things in the launch vehicles world that werent typically allowed.

Plans to use the spacecraft for regular space travel were mentioned in long-term NASA plans. The agency said the rocket could offer a new, low-cost path to space. And, by one estimation, the price to fly on the spaceship would only be as much as a world trip on the Queen Elizabeth 2 ocean liner.

As the program matured, a new and upgraded version of the rocket, called DC-XA, began testing at White Sands. In 1996, the rocket flew three times, reaching a height of 10,000 feet during one test.

In the control room, Dumbacher thought the end of DC-XA meant the end of his career. There was the rocket they had spent years working on and testing burning in front of them.

Then the phone rang.

Expecting a death knell, Dumbacher was congratulated by his boss on a job well done. Though the project had met a fiery end, it was ultimately considered a success. The team had developed and tested an entirely new spacecraft technology.

Some people will look at the last test as a failure, Dumbacher said. From one perspective, I can see that. From another perspective, we were allowed to push the envelope.

In less than two decades, that envelope pushing would lead to a new breed of spacecraft based on the same vertical launch and landing concept as the DC-X.

Opinion: Considering the first all-female space walk – CT Insider

We, as a country, have been in space for more than 60 years. Weve sent machines, monkeys, and men to space and entrusted each to gather important information about the universe to further human knowledge. But for the first time since we first launched a man into the dark expanse in 1961, this month we saw an all-female spacewalk, marking the beginning of our true preparedness for the beyond.

To embrace space travel, you must also embrace the value of the diversity of Earth. You must be able to see how men and women alike, and people of all races, are made equal in the safety of atmosphere and oxygen before you can hope to traverse the uncertainty of space. Principles like these are woven into the outreach of the Astronomical Society of New Haven (ASNH), an organization that has been serving southern Connecticut for more than 80 years.

Women have been withheld from doing stuff like this for a long time, said Greg Barker, President of the ASNH. In reality, they can do everything the guys can do. Space is pretty good in that way. You dont have to be physically stronger than another person, everything is weightless so its an equal playing field.

As an amateur astronomer with an oddly specific interest in astrophysics, I often consider the implications of our inability to see similarities in folks for really we arent too different. In that, I find it curious at best and damaging at worst to proclaim any assertion to progress past our atmosphere on to Mars while simultaneously planning for walls that separate and alienate us.

This month as astronauts Christina Koch and Jessica Meir took on the task of performing the first-ever all-female spacewalk, I confronted whether I should be excited, or dissatisfied.

On the one hand, I know that organizations like the ASNH are diligently working to ensure that a consistent love of space is coupled with a persistent valuation of skill and diversity and thats good. We need more of that. On the other hand, I grow increasingly concerned with our inability to practice those ideals from the safety of Earth.

When it comes to space travel, Barker said, You have to have everyone involved in it no matter who or what they are. Everyone has their place in this universe, and they need to be able to contribute it.

With regard to our contribution, there have been 339 Americans to space, which accounts for more than 60 percent of the world's astronauts. Of that number, fewer than 20 have been black, fewer than 15 have been Latinx, and exactly 40 have been women. Without even accounting for the various other types of ethnic groups, a clear pattern emerges in which its easy to assume space has been lacking in inclusion.

But is that important?

Youll find it hard to convince me that diversity in anything isnt helpful. Youll find it harder to convince me that when push comes to shove and a shove could be the difference between life and death having a team with a diversity of insight and skills isnt the most ideal scenario.

That is, in part, the value of local organizations working to ensure that anyone interested in astronomy has the tools, resources, support, and community to do so. Organizations like ASNH are a much-needed first step to ensuring an entire class of amateur astronomers can progress toward careers that will propel them to the stars. According to Barker, his organization is typically most attendees first introduction to the night sky from there, the interest to continue with the hobby and potentially the career in part relies on how much support you have to persist.

The organization regularly engages a group of Girl Scouts who, in addition to learning about the stars, are eager to have a hands-on experience with the telescopes and other stargazing equipment. With this group, he said, the most rewarding part is seeing their excitement after seeing the rings of Saturn. The most disheartening, though, is watching their interest wane over time.

If we get one out of every group to do something with space science or science in general, thats a plus in our favor, he said. Really, I dont know why their interest wanes after the years or if theres some other factor for why theyre not pursuing it. But the opportunity is there and theres nothing stopping them.

Im eager to see the future of this country ensure that girls and kids from diverse backgrounds have equal opportunity and support to pursue space science because, in the grand scheme of things, the sky is too limiting for whats possible for us.

Nasa reveals plans for probes that will travel 92BILLION miles from Earth 7 times further than ever before – The Irish Sun

NASA has announced plans for two probes that will travel further than any man-made objects in history.

The unnamed spacecraft will reach a staggering 92billion miles from our planet following their launches, set for 2030.

Thats seven times further than the record set by Nasas Voyager 1 and 2 probes, currently the furthest machines from Earth.

Both launched in 1977 and now sit just beyond the edge of the Solar System, or about 13billion miles away.

Proposals for an unnamed pair of probes were unveiled by Nasa last week at a space conference in Washington D.C.

This is humanitys first explicit step into interstellar space, said Dr Pontus Brandt, a physicist at the Johns Hopkins Applied Physics Laboratory.

AP:Associated Press

Put forward by Dr Leon Alkalai, who works at Nasas Jet Propulsion laboratory in California, the two probes would weigh 800 kilos.

Thats a little more than your average dairy cow, allowing the vessels to sail for great distances on little fuel.

To help them along on their journey, the probes would gather momentum by performing close passes of huge space objects.

These flybys would take advantage of the gravity of the Sun or Jupiter to slingshot the probes at speeds well over 100,000 mph.

Nasa

Scientists hope to use the missions to study a the mysterious outer regions of the Solar System and beyond.

Theyre keen to find out more about how space radiation enters our star system, and how solar radiation leaves.

Experts will submit the project for consideration by Nasa at the end of 2021.

Its not clear whether or not the space agency will choose to fund the mission.

Nasa

If selected by Nasa, the probes could fly as early as 2030, researchers said.

Its time we have a vision we can actually execute, Dr Ralph McNutt, a physicist at the Applied Physics Laboratory.

Up to now, people havent thought about this as an engineering problem. They kick the can down the road, saying: Well, we just need a little bit more new technology.

The plans were unveiled last week at the 2019 International Astronomical Congress.

The news comes almost a year after Voyager 2 became only the second man-made object ever to enter interstellar space.

Going where no machine has gone before...

Juno

New Horizons

Voyager 1

Voyager 2

According to Nasa, mission scientists were able to determine that the probe crossed the outer edge of the heliosphere on November 5, 2018.

This boundary is called the heliopause where hot solar winds meet the cold and dense intestellar medium.

Twin probe Voyager 1 crossed this boundary back in 2012.

But Voyager 2 is arguably more exciting, because it carries a working instrument that can provide brand new observations.

Specifically, it will measure the density and temperature of interstellar plasma, giving us new insight into a world beyond our solar system.

In other news, Nasa recently uncovered18 Earth-sized planetslurking outside our Solar System and one offers hope for life.

Watery Super Earths may hide unfathomably deep bottomless oceans withalien life lurking inside.

And, analien grain of dustfired at Earth by ancient exploding starhas been found buried in Antarctica.
