Immature Code or Good Test? Bitcoin Scaling Proposal Segwit2x’s Testnet Forks – CoinDesk

Posted: July 11, 2017 at 9:49 pm

Controversial bitcoin scaling proposal Segwit2x's testnet forked yesterday, creating two different and incompatible testnets.

Nodes running older bitcoinsoftware continued on as they normally would. But nodes running the new Segwit2x code stalled atblock 27070, meaning mining pools running the newsoftware were not mining blocks.

Overall, the nodes were stalled for over 20 hours as a result of the issue.

While there wasn't any real money on the line, the community was abuzz withthe news, some dismissing the controversial scaling proposal for perceived lingering issues, while others defended the misstep as only a small stumbling block that wouldn't happen during alive deployment.

Some developers argue the fork is a symptom of a larger trend of Segwit2x developers not listening to other developers who have worked with the bitcoin code for a long time. Bitcoin Core developers, for example, haveprovided feedback,pointing outperceived errors, but some of that has been ignored.

On social media, some argued the testnet fork stemmed from the implementation of the 2MB hard fork developers discussed and disagreed upona couple of weeks ago.

The 2MB hard fork is the second part of the Segwit2x proposal, an effort todouble the block size parameter, which will happen three months after the Segregated Witness (SegWit) activation.

This second part is important in that if not everyonein the bitcoin ecosystem upgrades to the 2MB increase (and many say they don't plan to), bitcoin could split into two assets. If that split is not made permanent, one chain could "wipeout" transactions that occur on the other chain, potentially leading users to lose money.

On the project's GitHub, developers had different ideas of how to solve that.

Segwit2x went forward with software that requires at least the first block is greater than 1MB. Somecontend this is what lead to the testnet fork, since there weren't enough transactions in the mempool, the part of the network where transactions are collected before being selected for blocks.

Bitcoin developer James Hilliard had proposed what he calls a "simpler and better" way of implementing so-called "wipeout protection," where nodes insert a piece of data making their blocks invalid to the other network.

Still, given that it's slated to be deployed in two weeks, for many, the bottom line is that it's too late for the codeto have serious issues.

Working group members are expected to install and test the code this Friday. Then, mining pools, companies and users are expected to begin running the code on the main bitcoin network as soon as July 21.

ButBloq co-founder and BTC1 developer Jeff Garzik argued the fork is not an event to worry about. One of the testnet miners simply triggered an event sooner than plannedand without preparation from the working group participants, he said.

According to Garzik, this split wouldn't happen once Segwit2x is deployed on the main bitcoin network.

He told CoinDesk:

"It falls into the category of 'jokers can disrupt test networks, because test networks have very little mining power security.'"

BTC.com's Boaz Bechar, who's also working on the Segwit2x implementation, offered a similar explanation.

While the testnet isn't expected to have many transactions flowing through it, the main bitcoin network will.

"Although unexpected timing, this is otherwise a good field test," Garzik wrote on the Segwit2x working groupmailing list. "This is the whole reason for a test network, after all."

Bitcoin rival, ethereum, has lost $17.5 billion in market value in 4 weeks – MarketWatch

Posted: at 9:49 pm

Ether, the worlds second-most valuable cryptocurrency, has been tanking since hitting a peak in mid June, highlighting an extended selloff in buzzy, digital currencies that had been on a tear only a few short weeks ago.

Check out: How cryptocurrency ethereum looks set to overtake bitcoinin one chart

A single ether token on Tuesday briefly slipped to a six-week low, dropping under $200 and marking a 48% decline, giving up about $17.5 billion since reaching its best-ever market capitalization of $36.7 billion on June 14, according to data from Coinmarketcap.com. Most recently, one ether was trading at 202.37, down 4.3% on Tuesday, according to data from popular digital-currency data-provider Coindesk.

The downdraft for ether, which powers the ethereum blockchain and is the main rival to more prominent bitcoin, is occurring amid a broad slump in the cryptocurrency universe, which had racked up dazzling, quadruple-digit gains within a short period. Ethereums ether, for example, had surged by more than 4,000% -- from $8 in January to its June peak of around $400 -- before mounting its recent pullback.

Read: Wall Street laughed at a call for bitcoin at $25,000but after a 400% surge, the laughter is fading

Attention from large corporations, including Fidelity Investments, and flirtations with the possible inclusion in popular trading products, like exchange-traded funds, also have helped to stimulate interest in bitcoin and other cryptocurrencies.

However, worries about the speed of the advance for digital currencies, light regulation and a lack of broad usage has given many skeptics reason to call for caution in investing in bitcoin and ether, which some analysts say displays similar attributes to gold GCQ7, +0.33% viewed as a haven asset.

More broadly, the combined market value of an array of digital currencies, including ether, bitcoin, and others like ripple and litecoin, are down by about 28% to $82 billion currently from $114 billion last month. Bitcoin BTCUSD, -2.91% maintains a dominant position among so-called digital currencies, but has led the way lower, off 20% since surpassing $3,000 a coin mid-June.

By comparison, the Dow Jones Industrial Average DJIA, +0.00% has tacked on 0.7%, the S&P 500 index SPX, -0.08% has slipped 0.2%, while the Nasdaq Composite Index COMP, +0.27% has advanced 0.3% over the past month, despite a choppy trading environment marked by concerns about earnings growth and President Donald Trumps Wall Street-friendly agenda.

All that said, cryptocurrencies are still holding on to sizable returns, even factoring in the recent downdraft. The question is: are they facing a brief pause in their rise, or suffering through what will become an extended period of pain?

Wall Street analysts are split on the future for cryptocurrencies. Morgan Stanley analysts predict that they wont rally further unless they get governmental acceptance, including more regulation.

Meanwhile, Fundstrats Tom Lee, a Wall Street equity strategist, says bitcoin may trade at $55,000 a coin by 2022.

Bitcoin and three other investments that look like classic bubbles but actually aren’t – MarketWatch

Posted: at 9:49 pm

Bubbles? Those arent bubbles.

Charles Schwab SCHW, -1.21% global strategist Jeff Kleintop says there are plenty of red-hot investments out there that might look like bubbles, but, in reality, they just dont fit the classic profile.

Bubbles typically bring risks for all investors, even those that dont own the inflating asset, he explained, because they represent a broader market and economy that has become out of balance and dependent upon a flawed outlook.

Previously, these bubbles of the past have inflated 1,000% over 10 years before bursting, cutting prices by more than half in the following two years, Kleintop explained. By the time they eventually popped, these investments had become fixtures across investors portfolio. Hence, the sweeping impact of their implosion.

As you can see from this chart, he pointed to the Nasdaq COMP, +0.27% crude oil CLQ7, +1.51% precious metals and home-builder stocks as obvious examples:

But what about those deemed bubbly in todays climate? Kleintop says the four most popular candidates are cryptocurrencies, low volatility, internet retailers and central bank assets. He applied his 1,000%/10-year filter to these investments

Remarkably, none of these seem to fit the classic profile of a potentially damaging bubble, he said. But that doesnt mean they dont carry risks for investors.

First, while bitcoin BTCUSD, -2.91% for example, has topped the 1,000%-return mark, it accomplished that feat much faster than the 10-year period.

Also read: Bitcoin rival, ethereum, has lost $17.5 billion in market value in 4 weeks

See also: Stay away from bitcoin and ethereum they are complete garbage

The shorter amount of time that it took may mean that if bitcoin is a bubble and were to burst it probably wont have as broad of a ripple effect on the economy as the technology or housing bubbles did, Kleintop said, pointing to this chart

Next, low volatility, specifically the VIX VIX, -1.98% is another area of concern. From one perspective, its 800% surge over the past 10 years pretty much matches the classic profile, but Kleintop says thats misleading.

While the pattern seems to line up fairly well with prior bubbles, he said, it would look different with a much larger rise and have more time to go until it reaches the 10 year time frame if I shifted the start date to the end of the bear market in March 2009, when volatility last peaked.

Then there are the internet retailers, like Amazon AMZN, -0.23% Clearly, these stocks have been on fire, but Kleintop says the relatively small size of the group keeps it from being a typical bubble and may limit the amount of damage a bubble pop would have on the broader market.

Unlike typical bubbles which tend to foster a purely optimistic outlook, these companies have already had a negative impact on the stocks of their traditional retail peers, leaving the overall retailing industry (composed of 10 sub-industries including internet retailers) up a smaller 500% over the same period, he wrote.

Finally, central bank assets, while clearly bloated by years of quantitative easing, dont exactly fit the mold, either. The balance sheets of the worlds central banks have grown about 300% over the past decade, coming up well shy of the 1000% level of the typical bubble.

The global buildup of debt most likely represents a long-term liability that threatens to exacerbate downturns, rather than a bubble about to burst, he noted.

Bottom line, Kleintop says that there doesnt seem to be any classic bubbles forming among the ones most commonly referred to as potential candidates. But remember that bubbles are sometimes only seen in hindsight, he said, which is why we always counsel diversification.

Chinese students to live 200 days in sealed space module with nothing going in and nothing coming out – USA TODAY

Posted: at 9:49 pm

If you have ever wondered what life on a different planet might be like, it might look a little like this. Susana Victoria Perez (@susana_vp) has more. Buzz60

They tried it with animals; now its time to try it with humans.

Yes, a group of human guinea pigs actually, four Chinese university students are trying to find out how it feels to live in a self-sustaining space station on another planet.

They are part of a project aimed at creating an ecosystem that provides everything humans need to survive, Reuters reported.

The students, from Beihang University, previously known as the Beijing University of Aeronautics and Astronautics, entered the Lunar Palace-1 module on Sunday with the aim of living self-sufficiently for 200 days.

The module containsfour bed cubicles, a common room, a washroom, a waste-treatment room and an animal-raising room, according to a report by the official Xinhua News Agency and the People's Daily newspaper.

"I'll get so much out of this," Liu Guanghui, a Ph.D student, who entered the 1,700-square-foot temporary residence on Sunday, told Reuters. "It's truly a different life experience."

Human waste will be treated through a bio-fermentation process, Xinhua reported,and vegetables and other crops will be grown with the help of food and waste byproducts.

The experiment comes as China seeks to become a global power in space exploration, with plans to send the first probe to the dark side of the moon by 2018 and to put astronauts on the moon by 2036, Reuters reported.

Liu Hong, a professor at at the university who is leading the project,said everything needed for human survival had been carefully calculated.

"We've designed it so the oxygen (produced by plants at the station) is exactly enough to satisfy the humans, the animals and the organisms that break down the waste materials," she told Reuters.

The project also is a test of the psychological impact on humans of a long stay on another planet.

"They can become a bit depressed," Liu told the agency. "If you spend a long time in this type of environment it can create some psychological problems."

The project's support team has found mapping out a specific set of daily tasks for the students is one way that helps them to remain happy, Reuters reported.

"We did this experiment with animals, ... so we want to see how much impact it will have on people," Liusaid.

Students will spend 6 months living in a ‘space station’ to test mental effects – SlashGear

Posted: at 9:48 pm

As part of its mission to send people into space, humanity has to answer many questions, and one of those questions involves whether humans are mentally capable of spending long periods of time within relatively tiny self-sustaining space stations. To help determine this, four university students have volunteered to spend 200 days living inside of a self-sustaining space station located in a Beijing suburb.

The four volunteers are students at Beijing University of Aeronautics and Astronautics, and theyre now officially residents of the Lunar Palace-1, where they kicked off their 200-day test on Sunday. The system is designed to supply everything theyll need, recycling everything the team produces while using plants for oxygen and special lights in substitution of sunlight. The team will not experience sunlight for the full 200 days.

Importantly, this project will also evaluate the mental effects of spending long periods of time in this type of environment. While the residency may not be burdensome in short cases, the long-term effects could be serious, possibly leading to depression or other issues. The researchers have created a list of daily tasks as a way to help combat any depression that may set in, but further data may lead to better solutions in the future.

The researchers are also specifically looking at how the prolonged period without exposure to sunlight will effect the volunteers, though Reuters reports that not much information was provided on that topic. This isnt the first time the Lunar Palace-1 has had residents; a previous 60-day run was performed, a time period in which at least one resident reported feeling a bit low after awhile.

NanoRacks CEO discusses trends in commercial space hardware – Phys.Org

Posted: at 9:48 pm

July 11, 2017 by Tomasz Nowakowski, Astrowatch.net, Universe Today Credit: NanoRacks

Founded in 2009, the Houston, Texas-based company NanoRacks LLC provides commercial hardware and services onboard the International Space Station (ISS) for government and commercial customers. To date, the firm has sent more than 550 payloads from over 30 countries to ISS, creating trends in commercial hardware in space. In an interview with Astrowatch.net, Jeffrey Manber, the founder and CEO of NanoRacks, talks about the company's future and past achievements.

Astrowatch.net: What are you future plans for the company? What is your priority for the coming years?

Jeffrey Manber: We are growing into the world's first commercial space station company. Today, our focus is on completing our commercial airlock on the ISS, which will allow far larger satellites and cargo to be deployed from the station. We are also moving forward on re-use of existing in-space hardware for commercial habitats and marketing other real estate in space, such as Blue Origin's suborbital New Shepard platform. We want to be the market leader in owning or operating as much real estate in space, from low-earth orbit to deep space to the moon and Mars, as is commercially possible.

Astrowatch.net: Your company is involved in many projects onboard the ISS. Could we call NanoRacks a trend setter when it comes to developing commercial hardware on ISS?

Manber: I would like to think that is correct. We were first to market on the station in owning and marketing our own hardware. We were first to have non-U.S. customers, first to have commercial satellite customers using the space station and we paved the way for using the space station in myriad commercial projects, from education to basic research to biopharma.

Astrowatch.net: How is your cooperation with NASA going? Do you plan some projects involving other space agencies?

Manber: Great question. The relationship with NASA has matured in many ways. NASA and the space station program office no longer question whether companies can and should make a profit providing services on the station using their own hardware. The space station office now supports our new projects, such as airlock, where we are self-funding. So the partnership with NASA has matured. They are at times a customer, they are our regulator and they are our landlord. Just as it should be in a commercial relationship!

We have very good relations with other space agencies. ESA is a customer of ours for satellite deployment. So, too, the European Union Commission. We work extensively within the Japanese module KIBO via the U.S.-Japan barter arrangement, so we have wonderful relations with the Japanese Aerospace Exploration Agency (JAXA) and so too with the Russian Space Agency (Roscosmos), with whom we work on both Progress and Soyuz.

NanoRacks is unusual in how deep is our relations with non U.S. space agencies. This is good as we look to return to the moon and move on to Mars.

Astrowatch.net: Are commercial space companies the future of spaceflight?

Manber: The industry is on the cusp of having space be just another place to do business. We are seeing multiple private launch vehicle efforts, we are seeing government behaving more and more as a customer. We are seeing companies like NanoRacks beginning to look beyond the International Space Station to see a marketplace where there are multiple space stations, all commercial, some unmanned for in-space manufacture, some manned as hotels, some for professionals to train for deep space missions.

Astrowatch.net: Which of NanoRacks' products on ISS is the most important for you and why? Which one was the biggest milestone for your company?

Manber: Right now our satellite deployment hardware is important because it is a large percentage of our current revenue! But as we look to the future, the airlock will be key, because not only will it increase our revenue from today for cargo egress and satellite deployment, but at some point in the future, we will remove the airlock from ISS and attach it to our own commercial platform.

How cool is that? Oh, I would say our biggest milestone was successful deployment of satellites. Or when we agreed to accept NASA funding for a research hardware called Plate Reader and NASA was nervous because we were new. So we agreed that if Plate Reader did not work, we would refund the taxpayers money. Luckily, it all worked! But I have not seen any other company make that same offer when taking the space agency's funding. But it was a turning point for us when NASA realized we were serious.

Astrowatch.net: You have recently made a statement that the company's mission is to democratize access to space. How close to achieving this goal is NanoRacks?

Manber: It is fair to say that after 550 payloads in seven years of operations from over 30 nations, including high schools and new nations to space, that after stimulating the growth of an entire new marketcommercial CubeSatsNanoRacks is today democratizing use of this incredible new frontier. Anyone, anywhere, from China to Vietnam, from Peru to Brooklyn, can and has used NanoRacks to undertake a commercial space research project. We have even had multiple customers whose funding came from crowd sourcing websites. It is a revolution and we are proud to be a leader in realizing this revolution in space utilization. Who knows what will be the situation in just five years?

SLS Upper Stage set to take up residence in the former home of ISS modules – NASASpaceflight.com

Posted: at 9:48 pm

July 11, 2017 by Chris Bergin

TheInterim Cryogenic Propulsion Stage (ICPS) is now deep into its latest phase of processing, as it prepares to be housed in theSpace Station Processing Facility (SSPF) a facility once packed with modules waiting for their ride on Shuttles to make up the elements of the International Space Station (ISS). The ICPS will be the Upper Stage for the maiden flight of the Space Launch System (SLS). ICPS:

The ICPS will only have a short lifetime with SLS, as the program aims to swiftly move to themore powerful Exploration Upper Stage (EUS)that will be the workhorse Upper Stage for SLS throughout the 2020s.

However, for the ICPS, the mission with SLS is only a change of call signs for this veteran unit, with years of previous and future service with the United Launch Alliance (ULA) Delta IV rocket fleet.

The official plan has revolved around moving to the EUS by the second or third flight of SLS, pending the readiness of the new EUS. The initial plan was to human rate another ICPS for EM-2, but NASA wants to bring the EUS online by the second SLS flight.

Based on the schedule slips for SLS and the large gap between EM-1 and EM-2 the plan is to revamp the Mobile Launcher umbilicals to cater for the Block 1B SLS after EM-1 (Exploration Mission-1) launches.

The EM-1 upper stage which is effectively a regular Delta Cryogenic Second Stage (DCSS) was shipped from the ULA facility in Decatur, Alabama aboard the Mariner barge earlier this year, arriving at the Cape in March.

It is currently housed in ULAs Horizontal Integration Facility (HIF) to begin processing for launch at the ULA Delta Operations Center. That work is now drawing to a close.

The next move will see it take a short journey to the SSPF, prior to a formal handover between ULA and NASA.

The Operations Planning team, specifically the Spacecraft Offline Operations (SOO) team are supporting the delivery of the Interim Cryogenic Propulsion Stage (ICPS) to the Space Station Processing Facility (SSPF). It is expected to be accelerated ten days from predicted August 1, 2017 to July 21, 2017, noted a Ground Systems Development and Operations (GSDO) update.

The SSPF is a three story structure containing 42,455 sq meters (457,000 sq ft) of offices, laboratories, and processing areas. It is located on NASA Causeway immediately east of the O&C (Operations & Checkout) Building.

The facility houses bays that were used for horizontal processing of components for the International Space Station and other Space Shuttle Payloads. With the payloads since launched on the now-retired Space Shuttle fleet resulting in the impressive orbital outpost that is now into its utilization phase the facility is almost empty of space hardware.

Prelaunch activities that took place in the SSPF included receipt, handling, and assembly of space station hardware, testing of experiments for proper configuration, and verification of critical systems and system interfaces. As such it makes it the perfect home for the ICPS ahead of its launch with the first SLS rocket.

The ICPS wont be officially handed over (or turned over) until some weeks after the ICPS arrives in the SSPF, allowing the Stages caretakers from ULA to continue to look after the ICPS and provide guidance to its new engineers.

Preparations are underway and include a contractor letter of direction for host role in the early weeks with the formal DD250 turnover to follow, hurricane plan development and approval, SSPF facility panel sampling, added the GSDO update.

(The) plan is for United Launch Alliance (ULA) access to perform monitoring and maintenance until formal turnover, and a likely transporter demonstration at the SSPF. All of these are to be addressed by the planned readiness review scheduled for July 19, 2017, at the Operations Processing Project Review (OPPR).

The eventual destination for the ICPS will bethe Vehicle Assembly Building (VAB) at KSC, in preparation for mating atopthe SLS stack.

The stack will be integrated while sitting onthe Mobile Launcher, which will provide the lifeblood of electrical and fluid support, along with the all-important prop loading whilst at the pad.

That connection between the ML and the ICPS will be the Interim Cryogenic Propulsive Stage Umbilical (ICPSU) will be a T-0 umbilical.

While some umbilicals have already been installed onto the ML, the ICPSU is expected to be connected in September to October timeframe well ahead of the timeframe the first SLS is scheduled to be mated with the ML in the VAB.

JCB Pioneer: Mars Bringing Realistic Colonization to Steam Early … – Capsule Computers

Posted: at 9:48 pm

Atomicom announced their hardcore survival PC gameJCB Pioneer: Marswill hit Steam Early Access in Winter 2017 (Summer 2017 in the Northern Hemisphere). Developed with guidance from astrophysicist Dr. Maggie Lieu, a research fellow at the European Space Agency;JCB Pioneer: Marsis setting its sights on being a realistic take on what early colonization of the Mars may actually look like. Atomicon also partnered with engineers from construction equipment firm JCB to create a variety of construction and mining vehicles that could believably find their way to Mars.

Players are among the first colonists send to Mars in hopes of finding a new home for humanity as Earth begins to collapse. They will start off in the wreckage of their landing pod. To have any hope of survival, they will need to quickly establish their first colony and secure their supply of oxygen. The colony will need a constant stream of materials for research, construction, and repairs as players contend with Mars hostile environment.

Study Says Life On Mars Will Have Fungus: Can Space Travelers Risk Infection? – International Business Times

Posted: at 9:48 pm

Theres a fungus among us wherever we go, even Mars, so scientists are studying fungi in space habitats to better understand how those microorganisms will affect astronauts on a mission to Mars or in a space colony.

They used an inflatable habitat with similar conditions to the International Space Station although on Earth, it simulates the sort of closed system astronauts would live in on the moon or on Mars, complete with air filtration. As students occupied the habitat for 30 days, the researchers collected fungus samples to find species that were environmentally common as well as pathogens that could infect humans. According to their study in the journal Microbiome, the fungal community became more diverse during the course of the human habitation, therefore, it is crucial to properly maintain a closed habitat to preserve it from deteriorating and keep it safe for its inhabitants.

Read: Vice President Mike Pence Says We Will Return to the Moon

The research took place alongside other studies of how humans react to a confined environment on a physical health level as well as on a psychological and behavioral level. Samples were taken from locations around the habitat throughout the length of the experiment. Some of the most abundant fungi collected were ones that are known to trigger allergies and asthma. And because previous research has shown that astronaut immune systems behave differently in space, the crew could face serious health risks. If stress leads to a decreased immune response in the space travelers, they could be more susceptible to a pathogen.

Understanding the microbiome of a closed system and its association with human inhabitation will help to assess the correlation between human health and microbiome of the habitat, the study says.

Cleaning procedures might be implemented as a safety measure during a colonization of Mars or another space journey, and indeed the researchers note that weekly cleanings in their model habitat included antibacterial wipes and could have affected the fungus samples they were able to collect.

But fungi tend to be hardy, so they present a challenge: Fungi are extremophiles that can survive harsh conditions such as low nutrient, desiccation, high/low temperatures, acidic/alkaline, radiation, and other environments, according to the research. Fungal species not only have been isolated from all known environments on Earth, including barren lands like deserts, caves, or nuclear accident sites, but also are known to be difficult to eradicate from other types of environments including indoor and closed spaces.

Even ones within the fungal community, known as a mycobiome, that are not known to cause deadly infection can be a problem. A report by journal publisher BioMed Central explained that one of the fungi collected is a common outdoor organism and while it does not often cause an infection in humans, it could trigger an asthma attack, particularly in someone whose immune system has been weakened during space travel.

Read: Can Bacteria Survive on the Mars Surface?

A protected habitat would be necessary for all foreseeable space missions because of the conditions on other planets and moons. Even if the Mars atmosphere was breathable, the air is too thin to support human respiration, even when its not choked with dust. And any water on Mars has long disappeared from the surface, putting another obstacle in the way of habitation.

The next step is to understand why the fungi populations in a closed habitat evolve the way they do.

In-depth knowledge of the viable mycobiome will allow the development of required maintenance and cleaning procedures in a closed habitat and also prevent it from deteriorating and becoming a health hazards to its inhabitants, corresponding author Kasthuri Venkateswaran, from NASAs Jet Propulsion Laboratory, said in the BioMed Central statement. However, to be able to show that increased fungal diversity is a result of human presence, the mycobiome of the occupants will also need to be studied.
