Interesting Use Cases and News about Cryptos/Blockchain Technology

  • some (very rich!) bad actor can start collecting his own
  • secretly mine his own valid chain with whatever transactions he chooses
  • and at some point when he surpasses the accumulated proof-of-work
  • he will broadcast his valid chain
  • and since it will be longer it will invalidate the original one

Whilst this is theoretically possible, once discovered wouldn't the value of BTC drop to practically zero and effectively be a waste of time and money by the bad actor?


What about Quantum computing, do you think this will become an issue for Cryptos that are not quantum proof? If so, when do you think it might become as issue?
 
Maybe the bad actor wants only to crash bitcoin.

About quantum computers i am not sure. There are cryptography upgrades to make something quantum-proof.
And I hear that, basically you have one shot to break something with quantum.
After that, everyone knows it is out there, and they upgrade.
It is just as easy to hack central banks and military bases, if you have a quantum computer.
Arguably the surprise attack will be wasted hacking Satoshi's coins.

Governments?

Thinking with my conspiratorial hat on (I rarely take it off :D), it wouldnt be beyond the notions of governments to use bitcoin as a tool to manipulate fiat currency markets, would it?
All unofficial of course.

Some of the predictions above are typically outlandish.

However, going beyond the noise, the concept of one world currency has already been in train for a considerable time, some 50 years ago apparently.

https://www.theguardian.com/business/2017/apr/24/imf-populism-nationalism-sdr-reserve-currency

With that in mind, what would a world currency look like? How would it operate? Who would be in-charge, or what would back it?

Clearly the Euro is flawed, a one-glove-fits-all approach applied to a cohort of disparate economies pulling and moving in all directions.
So perhaps, it is simply a pipe dream, but not really ever practical?

Unless of course....such a world currency was decentralized? Out of the control of governments and central banks interference? Sovereignty resting in the holder of the currency?

Perhaps a world currency would simply be an internet currency? But local fiat currencies in place in sovereign jurisdictions?

I don't know, but it is interesting to watch all this develop, interesting times ahead.
 
I speculate that there's at least one person in the world that can do the hashing etc in their head. The human brain could still be better than any computer that exists.
 
The Congregation of Faith in the Vatican today in its Easter message said it was considering using blockchain to monitor the issuance of indulgences. Whilst simony - the sale of indulgences - has long since been eradicated, the Vatican has expressed concern in recent years with the supply of indulgences. In a welcome development nuns as well as priests will be permitted to act as nodes though miner nodes will be restricted to bishops.

The overall supply has not yet been decided. Father Alonso Xabi, a leading authority on the subject, estimates that given the World's 700 million catholics the protocol should set the limit at about 200 bn years in purgatory.
 
Always looking for an angle to make a quick buck those Roman Catholics. It wouldnt surprise me if they are still trying to peddle that after-life stuff...what they call it?, oh yeah...the Resurrection :D
 
Hello,

I see [broken link removed] that some of the Russian hotels intend to accept payments in Bitcoin during the FIFA World Cup.

It will an interesting experiment, not least to see what sort of volumes are transacted (assuming we ever get to hear).

Sepp Blatter might be the first to take them up on the offer! :D:D:D

Might suit certain people who don't want to give their credit card details to a Russian hotel not to mention the exchange rates and associated bank charges etc. Will be interesting to see the volumes indeed.
 
Dr. Rolf Werner Head of Central Europe at Fujitsu joins the IOTA Foundation

Another heavyweight joins the IOTA Foundation adding to the long list of key industry players getting involved in the machine to machine economy. When the Trinity Wallet is released after Beta testing, it will be one of the best available. You will be able to see how slick the Tangle actually is by transferring IOTAs without any transaction fees and will only take a minute to complete (instantaneously once the network matures).

China Launches a $1.6 Billion Blockchain Fund

https://coinwrath.com/china-launched-a-1bln-blockchain-fund/


Ya gotta hand it to the Chinese government.....a blanket outright ban on Cryptos and then they plough $400m of their own cash into Cryptos and allow a Crypto fund of $1.6bn. I wonder if they'd pump that sort of twine into something if they thought it was just 'hot air!'

”digitized sovereign currency” this is the antithesis of bitcoin.
 
It's estimated that by 2025, there will be 100 Billion global IoT devices, sending data and transferring value in the new Machine-to-Machine reality. As everything becomes a "smart device" in the coming Economy of Things, what will be the underlying protocol that makes this all work?

Terry Shane, Founder of the bIOTAsphere in Toronto, and CEO of Refined Data Solutions explains why IOTA is the only Distributed Ledger Technology available today, that can achieve the scale and utility required.

If you are hoping that blockchain-based solutions were going to solve for this, Terry suggests that you might want to think again about where to place your bets.

This presentation was delivered as a keynote speech at the Blockchain Opportunities Summit, held in Toronto, Canada.

An excellent presentation by Terry Shane. This guy has a pretty decent ability to see around corners and sees IOTA as a potentially major player (the only player at the moment in fact) in the machine to machine economy.

100 Billion connected devices is no small number. The second part of the presentation is the most interesting as he goes through potential use cases etc.

This is beyond Blockchain folks so anyone who wants to stay stuck in the past, I'm warning you this video may be seriously harmful to your health! :D:D:D

Bithumb, South Korea’s largest cryptocurrency-to-fiat exchange and the world’s 6th largest digital currency trading platform ........ has installed cryptocurrency-accepting kiosks across the country, at restaurants, cafes, stores, and malls.

So, the USA has ATMs where you can buy cryptos, South Korea now have terminals where you can pay for various small goods in twelve different crypto currencies, online giants such as Expedia and Microsoft accept Bitcoin as a form of payment, and little old Dublin even has a crypto cafe... this worthless oul crypto coin stuff might just take off yet ! ;)

In South Korea, the largest hotel booking platform and second biggest e-commerce platform have started to integrate cryptocurrencies due to their partnerships with Bithumb. Soon, the majority of restaurants and cafes in Seoul will be equipped with cryptocurrency kiosks, as seen in the photograph shared by Ver.

Interesting article. South Korea are generally ahead of the possy when it comes to technology.
