UMI – the Best of Cryptocurrencies and Fiat Payment Systems

UMI – the Best of Cryptocurrencies and Fiat Payment Systems

https://preview.redd.it/dv0mdncf7sa51.jpg?width=1023&format=pjpg&auto=webp&s=b5928548ebdd497bc1cbad43dce27e29bfcbc42b
Greetings from the UMI Team!
The UMI cryptocurrency has been repeatedly described as a revolution in the payment system market. Most interestingly, in this case, a revolution isn't about the development of any new technologies or formulas. We just selected the best and well-tried technologies and incorporated them into something new. UMI is the best of cryptocurrencies and fiat payment systems––it has comprised all the best features and got rid of the disadvantages.
UMI vs banks
We won't compare the ways UMI and banks operate in detail in order not to get into complex technical issues, which are of no interest to us. Instead, let's have a look at the impact banks have on people on a daily basis and those of fundamental changes UMI makes to the services we regularly use.
There are banks that allow you to make financial transfers. Banks have savings accounts where money grows at a certain interest rate. Banks also have a range of mobile apps and online banking systems. All of that may appear pretty convenient. But keep in mind, the banking infrastructure, as well as VISA and MasterCard payment systems, were created long ago and based on old technologies. They are not conforming to present-day developments, mostly because they cannot ensure their users a sufficient security level.
With this in mind, instead of inventing something new, UMI improves the things that everyone is accustomed to. The result is a digital payment tool working in an absolutely familiar way. Conducting transfers with UMI is similar to making them via a bank. And even the format of UMI is much alike to conventional money––UMI and UMI-cents are the equivalent of the dollar and cents.
In UMI, just as in a bank, you have a current account (standard UMI address) and savings account––addresses used by structures for UMI staking. You can transfer money from one account to the other one in one click. The difference is that, in most banks, you receive your interest in a month at the earliest. In other words, you can get your money back with interest if you kiss it goodbye for 30 days, minimum. In UMI, earnings are accrued every second––you don't have to wait a long time for "your funds to be unlocked".
But what is the most significant is dividends. UMI staking allows any network user to earn up to 40% per month. Holding your money in a savings account even for a year, much less for a month, you will never make this profit. Why?
1) Because banks make good money on your deposits, instead of paying higher interests, they take the lion's share of what they could pay you into their pocket.
2) Secondly, a large part of your deposits is used to maintain the banking infrastructure: salaries for staff, rental payments, maintenance of offices, utility bills, and other various expenses.
3) Third, banks are not interested in making people rich, because otherwise, they will not be able to make money on loans and control people.
Let's not spout out empty rhetoric, but move on instead. The VISA and MasterCard payment systems declare their ability to process thousands of transactions per second, but in real fact, even if received funds are displayed instantly in your account, you receive a transfer after a few days only. Especially if it concerns international money transfers or ATM transfers. The truth is that VISA and MasterCard transfers are delayed by a series of confirmations required by banks and actually reach a recipient's account only in a few days.
After having been sent, any transaction can be blocked or canceled, and funds in your account can be frozen on the slightest suspicion. Even if before receiving all the confirmations required by banks, you have already withdrawn the funds via an ATM or transferred them to someone, the bank may take this amount from your account a few days later. Thus, you may surprisingly find out that your balance is negative. Keep in mind that banks charge transaction fees. Fees for oversea transfers may range from $10 up to 10% of the transaction amount. Thus, instead of $1,000, a recipient receives only $900.
The UMI network uses validator nodes which in a couple of seconds verify the correctness of transactions and allow users to check their balance for the sufficiency of funds. All transactions are instant. A transfer cannot be canceled or blocked, as well as money in your account cannot be frozen. Unlike VISA and MasterCard, transferred funds are available straight after a transaction has been added to the blockchain. Moreover, no fees are charged for that. Each and every transaction, international or not, is completely free.
Don't forget about permanent internet connection, which is required for conducting transactions with VISA and MasterCard. A validator node used by the UMI network can create any transaction, even offline one, with no Internet connection. You can send a transaction to the network via Wi-Fi, Bluetooth, or even a radio wave. Therefore, if there were a sudden cataclysm and people from all over the globe lost internet connection, the UMI network would easily adapt to new conditions and keep working.
UMI vs Bitcoin
Now let's compare the UMI network with the first-ever created cryptocurrency––Bitcoin. It has proved itself to be a reliable payment system, with a number of significant disadvantages, though. Let's focus on the most essential ones.
1) The transaction processing capacity of the bitcoin network is limited by the network itself. In the best-case scenario, it takes users several tens of minutes to receive their funds. However, quite often there is a several-hour, or even several-day, delay.
2) High fees. When the network is experiencing an increased load, transfer fees can skyrocket immensely. In 2017, there were cases where Bitcoin transaction fee reached a high of around $40. Under normal conditions, it's not that bad. A few-dollar fees are common for Bitcoin users.
3) Centralized mining pools. In the pursuit of profit from mining, greed-driven participants join mining pools thus undermining the idea behind decentralization and leading to centralization. The reality is that if several leading pools unite, they will control most of the hashing power and will be able to perform a 51% attack. The attackers will be able to send nonexistent bitcoins, confirm invalid transactions, and roughly speaking, manipulate the network as they like.

The reality is that we have a slow network that creates problems for itself. Moreover, if we talk about Bitcoin in terms of programming, the Bitcoin network is more similar to physical fiat money. For this reason, any actions with the code, including the development of wallets and applications, are a tough non-typical task that only the most advanced blockchain specialists can cope with.
While using the same technologies that Bitcoin is based on, UMI betters its disadvantages and incorporates only benefits. The network doesn't limit the block processing time, but instead, do everything to shorten the processing time and increase the network capacity. Modern cryptography algorithms reduce the load on nodes, thus allowing them to process more transactions with spending less computing power. The UMI network can process 500 million transactions carried out in the Bitcoin network over 12 years in less than a week. Each transaction will be completely free.
The concept of balances UMI uses is different from that of fiat money, but has a lot in common with the idea of digital money. For this reason, using UMI is so extremely easy. In a similar way, it simplifies the process of developing and maintaining new wallets and other applications. Contributing to the UMI ecosystem's growth is extremely convenient.
So, what's the most essential? Over its 10-year history, Bitcoin has demonstrated that its implementation of the idea of decentralization doesn't work at all. This is why UMI is based on decentralization implemented in a different way. Unlike Bitcoin mining pools, users join structures that help the network grow and support its effective functioning, with no threat to its security.
UMI is something that we all already use, but much better.
Consequently, UMI is not about anything super-unique, beyond understanding and comprehension. This is about the same old money that we use on a day-to-day basis. The same financial transfers, the same deposits that we have in banks, and the same blockchain technology and decentralization that Bitcoin is based on. The only difference is that UMI implements all the above-mentioned features in a lot better and higher performing way –– which is more convenient, secure, and higher-quality. UMI is a twenty-first-century universal money tool working for the sake of all people!

Why can't I learn new things as easily as when I was younger?

When I was in my late teens to mid twenties, I could pick things up very quickly; programming, soldering, bitcoin, computecell phone hardware and software repair, understanding quantum terms, etc... I've noticed now that I have a very difficult time getting started in to things I find amazing and fun, but don't have any idea what it's about
For example: I'm trying to get in to Raspberry Pi for a few different things, but it's all just going right over my head and almost feels like I won't ever understand it

Move over BTC futures, the world’s accredited millionaires can now profit by mining Bitcoin

obscure activity limited to cyberpunks and dominated by Chinese brands, can now be an alternative investment option for accredited investors looking to take a BTC bet.
Do you mine?
Bitfury, an Amsterdam-based Bitcoin mining operator, has launched its ambitious institutional investor program, allowing high-net-worth individuals and deep-pocketed corporations to gain exposure to Bitcoin via owning mining infrastructure.
Participants in the program will invest, via a legal vehicle, in the mining infrastructure and data centers that power Bitcoin farms in Canada, Iceland, Norway, and Central Asia, among others.
The firm announced all internationally accredited investors can join the program, detailing several benefits Bitfury offers over existing options.
Bitfury touts its access to low-cost data centers, electricity, and long-standing expertise in Bitcoin mining as some points that will attract investors. Sure enough, the company’s been around since 2011, making it one of the earliest, if not the earliest, commercial players in Bitcoin mining.
All operations will be managed by Bitfury, with the firm noting investors can track their financial progress and profitability “at any time online.”
With the launch, the program is one of the first to offer investment in, and subsequently profit from, mining protocols that power the Bitcoin network. Most institutional investors, such as Paul Tudor Jones, depend on purchasing BTC futures, swaps, or options either as a market hedge or long-term investment.
However, the above means taking a directional bet on Bitcoin, which remains a volatile market and is susceptible to massive plunges over a few hours. Security issues, such as wallet hacks or mismanaging private keys, are other limiting concerns.
Overcoming BTC obstacles
Bitfury CEO Valery Vavilov told Forbesthe product helps institutional players “overcome” obstacles that traditional routes of Bitcoin investing present, with family offices standing to benefit greatly. He explains:
“OUR STREAMLINED AVENUE TO DIVERSIFICATION IS DESIGNED SPECIFICALLY FOR THEIR PORTFOLIOS – EXPOSURE TO DIGITAL ASSETS WITHOUT ANY OF THE OPERATIONAL/TECHNICAL REQUIREMENTS OF HOLDING THE DIGITAL ASSETS/INFRASTRUCTURE THEMSELVES.”
Vavilov believes the recent institutional interest in Bitcoin and cryptocurrencies, and the presence of newer products like his firm’s, help propel Bitcoin to “great prestige among former skeptics.”
He notes investors were previously “locked out” of invest at scale, citing extensive set-up costs and operational expertise, alongside holding large amounts of Bitcoin.
“The introduction of institutional offerings like Bitfury’s program introduces bitcoin to an influential audience, helping solidify it as an asset class and shoring up support for the network’s continued expansion,” he concluded.

Youtuber Ivan on Tech talks about his discovery of Bitcoin, blockchain and his thoughts on Solidity

After his mathematician mom gave him an HTML book, Ivan Liljeqvist of Ivan on Tech read it over and over. “I remember very clearly there was a chapter about the objects and classes in C++,” he said. “I didn’t understand how it worked and why it worked. So I just kept re-reading it and then it clicked after awhile.”
When he began that book, which was the start of his programming experience, he thought he would know how to develop his own video games by the end. Instead, he came up a bit short, only knowing some HTML tricks.
He moved onto JavaScript, the high level programming language developed by Brave Browser founder Brendan Eich. And then, he spent time learning C++, because he had heard that it was, in fact, the right language to learn––if you wanted to learn video game programming, that is. He was stuck on that language for months, trying to understand how to build even simple apps. He learned about loops, objects, and classes. From there, it was smooth sailing.
In his youth, Ivan developed several video games, which were available in the app store, though none became popular-––he didn’t want to pay the developer fee to keep them online. These projects were mostly for learning, anyway. He remembers a library called the Cocos engine which he used to develop games for iOS platform, which, as a matter of fact, now has a blockchain library. After that, he began developing on OpenGL, though he realized early on how very low level it is.

Solidity
When he stumbled onto Bitcoin, Ivan liked that it was coded in C, because he was a bit familiar with that programming language. “I could easily start reading the code and understanding the code,” he said.
He said if they had chosen another language, say, Erlang or Haskell, while it would take a bit more time to understand, he’d probably get the gist of it soon enough. But, for me, it was good that they chose something that I am comfortable with.”
Because it’s a protocol, C++ was a good choice for Bitcoin, says Ivan. “You don’t really want to use Python or other higher level programming languages. With C, you have access to hardware to the extent that is not possible with higher level programming languages. So it is a natural choice, when you’re writing something like Bitcoin.”
He never programmed on Bitcoin, but his developer experience helped him learn certain aspects of Bitcoin, like hashing, digital signatures, and how a system of digital cash without intermediaries, without a central bank or company to control everything, works. When he entered into the space there were many colored coins projects, too, which he looked into from a technical perspective.
The main thing that really caught his attention, in terms of building applications on blockchain, was Ethereum and Solidity. “There you could truly program whatever you wanted and you had the fully fledged turing complete programming language, which is solidity,” said Ivan. “So it was a whole other level. And you could really express yourself as a developer in so many different ways that simply wasn’t possible on Bitcoin. “
A turing complete programming language, which is most these days, is a language that can do everything that a turing machine can do, which, in part, means it can do any type of calculation. A turing machine is powerful enough to compute anything that can be computed.
You can build whatever you want on Solidity, says Ivan. “You can express the logic, you can express what the network should do,” he says. “With Bitcoin, you don’t have a turing complete programming language, so you cannot tell the network to do all the things that you could with Ethereum. So Bitcoin doesn’t, for example, have loops. You cannot have a program that is repeating some kind of action over and over again, a certain amount of time to the same extent as on Ethereum. On Bitcoin you cannot really tell the Bitcoin network to do a lot, but on ethereum you have more flexibility. “
Solidity is a higher level programming language, similar to JavaScript, where you can create data structures. “You can use arrays, you can have loops, and you can really work like in a normal programming language,” said Ivan. “With Bitcoin, it’s a bit different, because you have a script which is a low level stack based, scripting language. It’s kind of like working in assembly. It’s very low level. You work with a low level operation. In Solidity, you work with your normal concepts, as you do in other programming languages, concepts like loops, classes, functions, methods, which you don’t have in Bitcoin.”

A small Pacific island will now let you pay for citizenship with bitcoin

A small Pacific island will now let you pay for citizenship with bitcoin

You can now purchase citizenship of the country with the world’s 34th most powerful passport with bitcoin.
The Vanuatu Information Center, which handles applications to the Pacific island country’s honorary citizenship program, announced this month that the center has secured government approval for taking fee payment in bitcoin. It’s the first citizenship investment program to allow payments in a cryptocurrency, the center noted in a statement. The immigration fee of $80,000 translates into around 20 bitcoins at the current market price of $4,843.
“Crypto-currency transactions are set to become very entrenched in global finance,” James Harris, managing director of the center and official representative for the investment citizenship program, told Quartz via email. “It makes sense for countries offering Citizenship by Investment Programs to respond to the inevitable adoption of crypto-currency for such transactions.”
Since the implementation of the Vanuatu Naturalization Donation Program in 2016, Rainbow City Immigration Group has taken root in Vanuatu. Its subsidiaries include a local newspaper(Vila Times), law firms, financial companies, real estate management companies, etc. in Vanuatu, and there are also branches in Shanghai, Shenzhen, Dubai, New Zealand and Vanuatu.
In the field of Vanuatu immigration investment, Rainbow City Immigration is the most experienced and authoritative company with a market share of more than 50%. The official and authoritative nature of Runpo City immigrants is unmatched by any company on the market. It is a true Vanuatu immigration passport application expert.

Airbnb Now Bookable With Bitcoin and Lightning Network via Fold App

Airbnb Now Bookable With Bitcoin and Lightning Network via Fold App
Bitcoin payments app Fold now supports home-sharing giant Airbnb, the firm announced on Nov. 11. Now Fold users can get 3% back in Bitcoin (BTC) on every stay and experience booked on Airbnb.
$25 and $100 Airbnb gift cards for Bitcoin
Airbnb is now listed on its rewards program called Fold Kickbacks. The program supports Bitcoin’s second layer Lightning Network (LN) allowing to buy gift cards for Bitcoin with 3% cashback. Currently, Fold offers $25 or $100 gift cards on its website.
Launched in July 2019, the Fold Kickbacks program already supports some big-name retailers including Amazon, Starbucks and Uber. However, the app works in selected countries including the United States, Australia, Canada, Ireland, Mexico and the United Kingdom, depending on the specific brand. The firm expects to roll out services in Europe in the near future.
In late September 2019, Fold raised $2.5 million in order to expand its platform with a fiat currency payment option. The new feature was added in late September 2019 and allows Fold users to spend both fiat currency and Bitcoin at online and in-store retailers by adding their credit card or Bitcoin Lightning wallet. To date, Fold app only accepts Bitcoin, the firm says.
More and more ways to “stack sats”
But while Fold is one of the oldest Bitcoin shopping rewards apps today first launched in 2014, it is certainly not the only one as many other options to “stack sats” are becoming available.
Lolli, another Bitcoin rewards shopping app, previously partnered with American pet retailer Petco in late August. Lolli also rolled out support for major American grocery chain Safeway to provide customers with 3.5% cashback in Bitcoin on all their purchases.
Elsewhere, Japan’s largest gift card platform Amaten announced its plans earlier this year to issue tokenized gift cards in partnership with blockchain network provider Aelf.

Oslo Freedom Forum Fringe Review [midipoet]

Oslo Freedom Forum Fringe Review [midipoet]
this is going to relatively long, so i apologise in advance.
there is a tl;dr at the bottom, so just scroll if you prefer.
All images are hosted on imgur, and the video posted is on Youtube.
Background:
Monero were asked to be represented at the Oslo Freedom Forum, which led to a CCS proposal and a plan to send me out to do a fringe type workshop while also attending the event. This proposal led to quite a long discussion on IRC (#monero-community).
