What are NFTs?
According to the Merriam-Webster definition, a nonfungible token (NFT) is a unique digital identifier which cannot be copied, substituted or subdivided. Once created, the NFT is then recorded in a blockchain which is used to certify its authenticity and ownership. An NFT is not a tangible object but rather a form of proof that shows ownership and purchase. These blockchain-based tokens can represent artwork, digital content, media or even event tickets. An NFT is an irrevocable digital certificate of ownership and authenticity for a digital or physical asset.

NFTs have unique digital identifiers and are stored on a blockchain, a system that is used to keep a record of transactions made in bitcoin or some type of cryptocurrency. NFT records are kept across multiple computers that are linked in a network and through the blockchain, can be sold or traded. NFTs are created through a process called “minting,” in which they convert digital files into a cryptocurrency collectible. The process of minting is how NFTs are uploaded to the blockchain.

Blockchain smart contracts can finally have a real world impact
A startup says it has tackled a long-standing problem that has kept smart contracts from responding to events in the outside world.

You have probably heard that blockchain technology and "smart contracts" are going to revolutionize our lives.

But there’s a problem: before smart contracts can do anything really useful, they need a reliable way to connect with events in the real world—and that has proved impossible so far. This is the so-called "oracle problem," a technological challenge that is still hampering any chance that blockchain will break out and become a part of our everyday lives.

Until now, perhaps. A startup called Chainlink is combining its software with a trusted hardware system called Town Crier, developed by a leading academic cryptocurrency research group. Together, they might be closer than ever to solving the problem.

Smart contracts are computer programs stored in a blockchain. They can be used to automate the unstoppable transfer of crypto-tokens between users, according to agreed-upon conditions. “Oracles” are real-time data feeds that deliver things like weather data, currency exchange rates, airline flight information, and sports statistics to smart contracts.

The idea is that by working together, the two systems can allow blockchain-based services to interact with real-world events with a greater degree of trust than is possible from today’s oracle services. For example, if your flight is canceled but you bought flight insurance, a smart contract might instantaneously pay you after getting an update from a trusted source of flight times.

IBM hat mit dem Crypto-Anchor den kleinsten Computer der Welt entwickelt. Das System soll künftig in neuartigen Edge-Lösungen zum Einsatz kommen.

IBM stellte auf seiner Hausmesse „Think 2018“ mit dem Crypto-Anchor den kleinsten Computer der Welt vor. Er ist kleiner als ein grobes Salzkorn. Damit unterbietet er den Michigan Micro Mote, der rund doppelt so viel Platz benötigt. Vorerst nur ein Protoyp, soll der Crypto-Anchor künftig als Edge-Gerät an Produkten zum Einsatz kommen, etwa zur Echtheitsprüfung von Medikamenten.
Eckdaten

Der Mini-Computer erreicht die Rechenleistung eines x86-Prozessors aus den 1990er-Jahren
In der Herstellung kostet er weniger als 10 Cent
Zur Authentifizierung von Daten greift der Crypto-Anchor auf eine Blockchain zu

Details
IBMs Crypto-Anchor hat eine Größe von 1 x 1 Millimeter. Das große Bild auf der linken Seite zeigt übrigens nicht nur einen Mini-Computer – auf dem Chip, der auf der Fingerkuppe liegt, be­finden sich vielmehr 64 Stück davon. Der Prozessor des Kleinstrechners verfügt über rund eine Million Transistoren. Das entspricht in etwa der Zahl an Tran­sistoren früherer 486er-Prozessoren von Intel. Die Datenübertragung erfolgt über eine LED. Ein lichtempfind­licher Sensor empfängt Daten von außen. Der Crypto-Anchor verfügt über eine integrierte Solarzelle. Sie ermöglicht einen komplett autarken Betrieb des Edge-Geräts. Das Edge-Gerät soll als „kryptografischer Anker“ Lieferketten überwachen oder Produktinformationen speichern. Für die Authentifizierung und Prüfung der Daten setzt IBM auf eine Blockchain.

Les spéculations vont bon train sur les places de marché NFT. Pourtant, les risques de se faire avoir sont nombreux, et même de plus en plus. Voici quelques vérités qui font mal.
Le marché des NFT, ces objets de collection virtuels, est en pleine ébullition. On ne compte plus le nombre de punks, singes et autres gorilles dont on peut acheter la trombine, à des prix parfois très élevés. Cette frénésie spéculative incite de plus en plus d’internautes à sauter le pas et à investir leur bas de laine dans ces Ovnis informatiques.

Pourtant, les risques de se faire avoir sont très nombreux. Non seulement ce marché est très faiblement régulé, mais son architecture technique est également intrinsèquement déficiente, comme le montre les hacks et arnaques qui sont révélés presque quotidiennement. Voici donc quelques points de réflexion qui devraient vous passer l’envie d'acquérir un NFT.

1) Acheter un NFT, c’est acheter... du vent !

The amount of scams and fraud in the NFT space is overwhelming," the internal letter, which over 400 employees have signed, reads. "We implore you to reconsider."

Indeed, the NFT space is rife with shady dealings and theft. In January, OpenSea, which bills itself as "world's first and largest NFT marketplace," admitted that "over 80%" of NFTs minted using its free minting tool "were plagiarized works, fake collections, and spam.

Take a moment and think of everything wrong with the online world, from data breaches to violations of privacy to the overweening power of big tech.

Then imagine them disappearing. Gone. Just like that.

Sounds appealing? Well, you've just heard the first line of a sales pitch-cum-revolutionary manifesto that's gaining traction in San Francisco and Washington DC. It goes by the name of web3.

The gist is familiar from revolutionary statements throughout history. Wrest power from the establishment, return it to the people, make everyone happier and richer along the way.

The tools we're told can achieve this are as modern as it gets. The heart of the plan is to rebuild the foundations of the web using the blockchain technology that underpins cryptocurrencies such as Bitcoin.

According to Web3's backers, it is possible to take anything - or, indeed, everything - that is online and put it on the blockchain, the energy-intensive ledger which enables data to be stored collectively without the need for a central record-keeper.

"You can use it to create scalable blockchain networks that use the Hyperledger Fabric open source framework, with Ethereum in the works," Barr said in a blog post today. "You can create your network in minutes. Once created, you can easily manage and maintain your blockchain network. You can manage certificates, invite new members, and scale out peer node capacity in order to process transactions more quickly."

Amazon Web Services (AWS) has joined a list of BaaS providers that already includes IBM, HP, Microsoft, Oracle and SAP.

March 19 is the first day of IBM Think 2018, the company's flagship conference, where the company will unveil what it claims is the world's smallest computer. They're not kidding: It's literally smaller than a grain of salt. 

But don't let the size fool you: This sucker has the computing power of the x86 chip from 1990. Okay, so that's not great compared to what we have today, but cut it some slack — you need a microscope to see it. 

The computer will cost less than ten cents to manufacture, and will also pack "several hundred thousand transistors," according to the company. These will allow it to "monitor, analyze, communicate, and even act on data."

According to IBM, this is only the beginning. "Within the next five years, cryptographic anchors — such as ink dots or tiny computers smaller than a grain of salt — will be embedded in everyday objects and devices," says IBM head of research Arvind Krishna. If he's correct, we'll see way more of these tiny systems in objects and devices in the years to come.
