    If people aren't allowed to think for themselves, how can computers be allowed to promote independent thought?

    China wants to ban Bitcoin mining because it 'seriously wasted resources'
    The state planner has lumped it in with coal and other polluting industries.

    China Says Bitcoin is Wasteful, Now it wants to Ban Mining

    China Considers Ban On Cryptocurrency Mining Because It's A Stupid Waste Of Energy
    Matt Novak, Apr 10, 2019, 8:30am
    https://www.gizmodo.com.au/2019/04/...-mining-because-its-a-stupid-waste-of-energy/

    "Regulators in China are considering a ban on cryptocurrency mining as an “undesirable” economic activity, according to a government document released Monday.

    China’s National Development and Reform Commission (NDRC) published a new paper that includes a proposal to ban the mining of cryptocurrencies like Bitcoin over concerns that crypto mining is a waste of valuable resources — a fact that’s hard to disagree with when you examine the horrific environmental impact. The proposal is available for public comment until May 7.

    Cryptocurrencies like Bitcoin are mined using specialised computers that sap a tremendous amount of energy. That energy consumption now rivals the amount used by entire countries for normal operations and is doing significant damage to the planet.

    As the South China Morning Post points out, China’s coal-dependent regions like Xinjiang and Inner Mongolia have become popular destinations for crypto-miners looking for cheap electricity.

    It’s estimated that as much as 74 per cent of global crypto mining is occurring in China, a place where it’s also the most carbon-intensive. According to a recent report in Nature Sustainability, crypto mining emits anywhere between 3 million and 15 million tons of carbon dioxide globally.

    China’s proposal to ban mining is part of a larger push against cryptocurrencies in the country over recent years. The People’s Bank of China banned initial coin offerings (ICOs) in September 2017 but crypto fanatics claim it’s easy to get around that ban.

    That being said, it would be much harder to circumvent a ban on crypto mining in the country since the energy consumption alone tends to give away the location of the computers necessary to make it happen.

    One of the founding myths of cryptocurrencies is that fake money like Bitcoin isn’t dependent on society at large to operate. But nothing could be further from the truth. Bitcoin and other cryptocurrencies rely on modern infrastructure and cheap energy to stay in business and once governments start cracking down on cryptocurrencies, they become a less attractive asset for mainstream financial institutions and consumers alike.

    Bitcoin has become little more than a speculator’s death cult, given the amount of damage that cryptocurrencies are doing to the planet. And while the Chinese government gets a lot of things wrong, a ban on crypto mining seems like a perfectly sensible move in the face of global environmental disaster.

    EY launches smart contract testing service for blockchain clients

    "EY announced today the launch of EY Smart Contract Analyzer, a smart contract testing and security service for the public Ethereum blockchain."

    https://www.ey.com/en_gl/news/2019/...ntract-testing-service-for-blockchain-clients

    Great news for Ethereum fans, as EY is using the public blockchain and not a private one.

    (For those unfamiliar with the financial industry, EY is one of the top 4 global accounting firms. Probably should've accepted their job offer way back when.)

    Personal Opinion time: head's up it's crypto "sucker" season again. :)

    I would have thought that with all the tragic losses over the last couple of years, with people putting their whole "nest egg" into crypto, only to find out you can't "cash out" your "winnings" fast enough before the value drops below what you paid, and that people would have learned or been burned enough to not get caught up in it again.

    You can't get something for nothing.

    You can indeed loose everything, and get nothing for something.

    The key is to work smartly over the long term, invest in yourself - learn a skill and be a valuable resource others need and are willing to pay you to do your craft, then invest in long term secure (that's the trick) investments that will at least maintain value (including inflation), if not appreciate against inflation over time.

    Crypto BS like Bitcoin and "magical" money are just that, fairy tales and pixie dust with which suckers will get their money taken, and others will benefit. If you think you are going to get in on the side of the takers vs the the taken, then you are a sucker too.

    Take this time when the price is pumped up to get out of crypto, cash in your chips - it takes a long time to convert it out into "real" money so start now while it's still going up in value, and then once you are out of it, stay away from it.

    If there are ever secure electronic payment systems, with price / value that is locked to the dollar or other secure currency, and backed by the federal government against losses, then that's the time to dip your toes back in.

    A digital "stable coin" is not going to be "money maker" but it would be designed to be a stable value that you can depend on being there for your lifetime and be there when you retire.

    That would be magical enough for me. :)

    And, don't fall for the hype machine, it'll look just as good as it did before, "reasons" will be believable if you don't look too closely, but it'll be the same drawn out pump and dump (whales), with lots of losers at the end sitting with boxes of gpu's and racks of useless miners / PC's wondering "what the hell just happened?".

    Why Bitcoin's Revival Is Different This Time Around
    Bloomberg Technology
    Published on May 16, 2019
    May.16 -- Barry Silbert, Digital Currency Group founder and chief executive officer, discusses what's behind the revival of Bitcoin with Bloomberg's Joe Weisenthal, Romaine Bostick and Caroline Hyde on "Bloomberg Markets: What'd You Miss?"


    Bitcoin [BTC] Whale Alert: BTC worth over $38 million moved in two transactions
    Aakash Athawasya, May 19, 2019
    https://ambcrypto.com/bitcoin-btc-whale-alert-btc-worth-over-38-million-moved-in-two-transactions/

    So far the whales have mutually bumped up the price again, it will only stay up there if the suckers start investing - institutional investers and then the individuals that see that and become hooked onto the sucker train.

    Hopefully 'smart' people will have learned - been stung enough - and will stop burning / wasting valuable natural resources powering mining, and the suckers and scammers can live within the already generated coinage ecosystem.
    Blockchain Chicken. Also from 2 years ago - 2017, Bock! Bock!!

    Block Bird's
    THE WORLD’S MOST TRANSPARENT CHICKEN.

    http://thefuturemarket.com/block-birds
    [​IMG]
    $10.99
    Block Bird’s is the first, fully transparent supply chain line of chicken products verified by Blockchain technology. All chicken is sourced from a multitude of small farms in the American midwest, where the entire journey of the chicken, from egg to grocery store, is recorded and plainly visible on the front of the package. Block Bird’s uses state of the art interactive e-ink packaging to show the entire chain of custody, all feed and inputs, as well as the health and handling history of the chicken you’re about to eat. With Block Bird’s, you can be absolutely sure that you’re getting the finest, most well raised chickens on the planet. That’s the power of the Blockchain to create the World’s Most Transparent Chicken.

    ABOUT BLOCK BIRD'S
    People who buy Block Bird’s have access to the entire life story of the chicken that they’re about to eat. This level of transparency is a check to ensure that the animals are raised according to the highest standards possible, as there’s nothing to hide from the end user.

    With wide scale adoption of blockchain technology and IOT sensors on farms, tracing where our food comes from has never been more of a streamlined, honest, and eye-opening process. Attempting to track the entire journey of a food as it goes from farm to fork is a daunting task.

    As of 2017, much of the farming / supply chain system relies on paper record keeping which is prone to inaccuracies and doesn’t enable easy data processing once the records are created. For areas of the supply chain where digital systems are keeping tabs on how food moves, systems are typically closed off and data is not shared throughout the entire chain. The lack of a central methodology to record, authenticate, and share data across the chain makes traceability extremely difficult.

    The blockchain records all data about a food’s journey in a central ledger that is nearly impossible to falsify or hack. Not only is there a much higher level of security to protect the validity of the data being tracked, the blockchain serves as a universal language that can seamlessly interface with the myriad stakeholders who touch a food as it is grown, processed, and distributed.

    On the front of pack, the story of the chicken’s entire lifespan is told from birth, to slaughter, to delivery to the grocery store. The chicken package label is made of a flexible e-ink touchscreen that the customer can navigate on pack data with their fingers. Chicken containers are disposable, but the flexible touchscreen is returned to the grocery store (similar to bottle return) for a deposit refund.

    Rest assured, every chicken eater with a need to know where their food is coming from and how it was raised, now has ironclad assurances that the food data they’re looking at is an honest reflection of the truth.
