ENS (Ethereum Name Service) domains are familiar names for the decentralized world. They provide a way for users to map human-readable names to wallet addresses, smart contracts, NFTs, IPFS content, or any other assets on Ethereum and dozens of other networks.

Domain Name System (DNS) domains are the traditional domain names used on the Internet. They allow users to access websites and send emails using familiar names such as example.art.

With matching ENS and DNS domains on .ART, users can take advantage of the best of both worlds: a name that works on the Web2 and Web3 platforms.

For example, if you own yourname.art as a DNS domain, you can also register yourname.art as an ENS domain pointing to any digital asset in the Etherium blockchain (just like an .ETH domain). The same name can also be used as a web address in any web browser pointing to a website, and also as an email address (something the .ETH domain cannot do). This makes .ART domains future-proof and versatile.

“We are thrilled to launch this new feature that connects Web2 and Web3 with our unique .ART extension. We believe that this will open up new possibilities for artists, collectors, curators, galleries, museums and anyone who wants to express themselves creatively online or on Web3. Our vision is to make .ART domains not only a digital identity but also a digital asset that can be used in various ways on different platforms”,

said Ulvi Kasimov, Founder of .ART Domains.

.ART is also collision-proof: only the owner of a DNS .ART domain can register the matching ENS .ART domain. Similarly, if an ENS .ART domain is registered for an available DNS .ART domain, only the person who owns the ENS .ART domain can use the DNS .ART domain. This ensures that there can be no confusion or conflict between different owners of similar names.

.ART is the first domain registry to offer this innovative matching domain capability across both ENS and DNS, making .ART domains more powerful and useful than any other blockchain capable domains.

The celebrities touted tokens sold by EthereumMax or EMAX. The idea was to boost its price and make a profit “at the expense of their followers and investors.”, claims the lawsuit, filed Jan. 7 in Los Angeles federal court. The lawsuit stated:

“The company’s executives, collaborating with several celebrity promoters … made false or misleading statements about EthereumMax through social media advertisements and other promotional activities.”

Kardashian promoted EthereumMax in a June 2021 post on Instagram,  when she had 250 million followers, according to the lawsuit.

“Are you guys into crypto?” she wrote in the post, followed by the disclaimer “this is not financial advice”, but that she wanted to share “what my friends just told me” about the EthereumMax tokens. She included the #AD hashtag to show the post was a paid advertisement, the lawsuit said.

Mayweather promoted EthereumMax on his boxing trunks during a widely viewed fight with YouTube star Logan Paul in June. There were also other times he did that.

Representatives for Kardashian and Mayweather did not immediately respond to requests for comment.

EthereumMax, the company, was also named in the lawsuit. In a statement  EthereumMax said:

“The deceptive narrative associated with the recent allegations is riddled with misinformation about the EthereumMax project. We dispute the allegations and look forward to the truth coming out.”

A New York resident who bought EMAX tokens and lost money filed the lawsuit. It is proposed as a class-action suit for anyone who bought EMAX tokens from mid-May to late June 2021. The case seeks restitution and disgorgement of profits by the defendants.

The plunge follows a volatile week for financial markets. Global equities and benchmark US bond yields tumbled on Friday after data showed US job growth slowed in November and the Omicron variant of the coronavirus kept investors on edge.

Bitcoin was 12 per cent down at 9.20 GMT at $47,495 (€41,980.83). It fell as low as $41,967.50 (€37,095.07) during the session, taking total losses for the day to 22 per cent.

By 22.01 GMT, it had rebounded slightly to $48,752.15 (€43,092.03) having lost $4,991.54 (€4,412.02) from its previous close.

The broad selloff in cryptocurrencies also saw Ether, the coin linked to the Ethereum blockchain network, plunge more than 10 per cent.

It rebounded to losses of 3.61 per cent to $4,070.52 (€3,597.93), losing $152.28 (€134.60) from its previous close.

More than 4% to as high as $66,170 jumped Bitcoin, approaching the unprecedented $67,016.50 level reached on Oct. 20.  Meanwhile ether – which underpins the Еthereum network – sat at a record top of $4,768.07.

Kyle Rodda, analyst at broker IG Markets said Reuters:

“Falling real yields, as traders brace for inflation, adds to the attractiveness of assets such as gold and cryptocurrencies which do not pay a coupon. The mood in the sector has also been good.”

Ether is up around 59% since the start of October and bitcoin about 51% as investors have cheered last month’s launch of a U.S. futures-based bitcoin exchange-traded fund and sought exposure to an asset class sometimes regarded as an inflation hedge.

What is Solidity

Solidity is the language in which most smart contracts are written. This means that anything from NFTs to Defi dApps might be written in Solidity. it runs on the blockchain and the code is stored there as well. This means you cannot have any bugs since you cannot update the contract once it is deployed.

Luckily for Ethereum, Polygon, and other blockchains have several tenets on which we can test our smart contract’s code before we deploy it to the real world main nets.

New Syntax

For this next part, I will assume you have some programming knowledge. Anything from functions and variables to classes and interfaces. Solidity isn’t hard to learn but it does have its quirks you need to keep in mind.

Mappings

Mappings are a way to store data in Solidity. When given a key, they will retrieve the value for you. For example, the owner of a token given by index.

They are often used to keep track of the owners of tokens. But in more intricate smart contracts they often have lots of uses.

Functions

The syntax for functions is pretty standard across languages. Solidity has a slightly different syntax because of modifiers.

The scope indicates who can call the function. This would be private , public , internal or external . A view function doesn’t cost any gas fees but it can only be read from the chain.

Modifiers

Modifiers make sure that only certain users can execute a function. The most used default modifier is the only owner which makes sure only the owner of the contract can execute the function. But you can make your own.

the _; syntax lets the code return to the function called the modifier. If you call _; the code will assume that the condition has passed.

There are a lot of checks you can do with modifiers that you would otherwise have to do in the function itself. If you are a developer in any other field, this wouldn’t be hard to learn. If you’re a new developer, I might have to write another article for you. Solidity is a language that is fairly new and will change over time. If you want to learn it from scratch without Medium, I highly suggest Crypto Zombies learn the basics of the language.
