We know cryptocurrencies used as financial support for smart contracts, asset tokenization, or derivatives trading. Tech geeks though went much further out of the box developing fabulous, cute, warmhearted, honest, and sometimes hilarious projects on the blockchain.

The blockchain community has always been creative with in-jokes and memes. Early crypto adopters share signs, symbols, and behavior models – from yelling “MOON” in trollboxes, to HODLing, to the entire existence of Dogecoin, which was pumped by Elon Musk and Tik Tok users recently

The technology that powers Bitcoin can be difficult to comprehend. Blockchain is a digital ledger platform that verifies identities and transactions through a secure digital network of records. It’s especially secure because it generates multiple records stored in a decentralized manner. The data stored on distributed ledgers can’t be altered or erased.

In turn, blockchain empowers people to trade and transact more, because they can be sure who they’re trading with, as well as the origins of the assets they’re trading. They can even generate new things to securely trade, from their time to virtual cats. 

The great art project of our age is to entirely collapse the distinctions between “fraud” and “performance art,” so that one day mortgage-bond traders will be able to say, “Wait, no, I wasn’t lying about bond prices to increase my bonus, I was performing a metafictional narrative about bond-price negotiations in order to problematize the underlying foundations of bond trading in late capitalism.

Magic money out of (thin?) air

A blockchain project with a postwork dystopian twist, Max Dovey’s Respiratory Miner allows people to mine cryptocurrency by breathing. Breath (BRH) is a part of an art performance and interactive exhibition that uses spirometry, the medical technique for measuring lung capacity, to mine Monero-based token with a hash rate adjusted for rate-of-breath. It was first displayed at Generator Projects in Dundee in an exhibition curated by Alejandro Ball and Inês Costa, and shown again as part of Money Lab in 2018.

Breed your virtual pet

In late 2017, a game called CryptoKitties debuted and generated more than $1.3 million in transactions of virtual cats in just over a month, becoming the biggest blockchain game. A studio called AxiomZen created the phenomenon, powered by the Ethereum cryptocurrency blockchain, which offers players to collect and breed digital cats. In 2017, TechCrunch reported that the price of one CyrptoKitty ranged from the equivalent of roughly $12 to $113,000. A year later CryptoKitties announced it had raised $12 million in funding from Andreessen Horowitz, Union Square Ventures, and other investors.

Time is money – literally!

Startup founder, software developer and open source advocate, Evan Prodromou came up with a solution to keep at bay all of the people who asked to “pick his brain” – he created a cryptocurrency called Evancoin on the Ethereum blockchain, backed by his time. Prodromou didn’t commodify all of his time, just professional time. Fortunately for his family, they don’t have to pay to get him to join them at the dinner table.

As Wired reported, basic economic principles govern Evancoin – the cryptocurrency’s value could theoretically shift along with supply and demand. Two weeks after the ICO, those in possession of Evancoin could also sell it for $45 per hour, which was less than Prodromou’s hourly consulting rate, but he was into it to see what would happen upon making his own blockchain-based currency.

I’m really serious about exploring how cryptocurrency is changing what we can do with money and how we think about it.

Know your dinner’s… life 

Some people have been always concerned about the origins of their food. That’s why international food conglomerate Cargill presented a solution for Thanksgiving dinner, so people can meet closer the life… of the turkey, they are gonna eat. 

Turkeys distributed from select farms featured packaging printed with a tracking code, and buyers could go online, type in the code, and learn about their individual bird. The online profile was complete with photos, information about the farm where the turkey was raised, and even a message from the farmer.

Store store your love for each other, forever!

And don’t forget there’s no divorce on blockchain, as smart contract data can’t be erased or modified.

Life is not eternal and death can separate us, but the blockchain is forever.

David Mondrus and Joyce Bayo about their blockchain wedding

Smart contracts have already found widespread use in trade finance because they can settle transactions without the need of a third party for verification. If the blockchain really is forever, it can be a cheap and innovative way to get married. 

The tradition of common law defines marriage as a private, voluntary agreement between a man and a woman. In the modern age, some nations have amended this law to include same‐sex couples. Just a few years ago a Swedish sportswear brand Björn Borg had an idea on utilizing blockchain to record the holy act of getting married, mainly due to barriers people of same sex have to get married by traditional methods.

… And record your sexual consent 

In January 2018, Amsterdam-based startup LegalThings, which specializes in digital contracts, launched a beta version of an app called LegalFling, which uses blockchain technology to verify sexual consent. Its creators were inspired by the #MeToo movement, which has brought to light numerous accounts of sexual assault. 

The app goes beyond recording whether a user has agreed to have sex. Users can specify requirements and whether certain practices are ok with them. The person’s acceptance gets recorded on the blockchain, so neither party can tamper with that record after that time.

Personal trainer for Buterin

“Help Vitalik Buterin get in shape” says the homepage of FitVitalik project. Because some people are much too busy thinking about our future. They’ve forgotten to think about theirs. The crypto community’s mission is to help one altruistic yet self-neglectful genius – the co-founder of the Ethereum Foundation and blockchain developer Vitalik Buterin – get in shape. The project’s roadmap includes gym membership, healthy sleep pattern, and diet and nutrition plan along with a personal trainer.

Is this a joke?

– No, this is 100% serious.

Don’t buy this coin!

Let’s be honest – everyone’s tired of ICOs. There are so many useless tokens out there, but this one truly is! Useless Ethereum Token (UET) – the world’s first 100% honest cryptocurrency on the Ethereum blockchain. No value, no security, and no product.

Wait… is this a joke? Is it a scam?

– Neither! This is real—and it’s 100% transparent. You’re literally giving your money to someone on the internet and getting completely useless tokens in return. There are no “whitepapers,” no “products,” and no “experts.” It’s just you, me, your hard-earned Ether, and my shopping list.

Will UET be traded on any exchanges?

– I hope so. You have no idea how much I hope so.

Why are you doing this?

– Who knows? Maybe it’s because I lost money in the GDAX flash crash. Maybe I got inspired by the guy who crowdfunded the potato salad.

– What can I do with UET?

– UET is a standard ERC20 token, so you can hold it and transfer it. Other than that… nothing. Absolutely nothing. Seriously, don’t buy this. Why are you even still reading these?

How do I get a refund for the tokens I bought?

– You’re kidding, right?

This one’s basically a meme blockbuster, listed on HitBTC, and at one point trading at $4.95. Yet, it also had an early and less-well-known predecessor, PonzICO.

The subtle art of giving a f*ck on blockchain

FuckToken is a social cryptocurrency that aims to help everyone around the world give a FUCK. It’s listed on CoinMarketCap and one FUCK is currently valued $0.01. The most ridiculous blockchain project comes from a beautiful idea of a community that promises to offer support to people struggling with personal issues, whatever they might be. The main point is that people nowadays do not “give any f*cks,” and in order to show your friends that you care about them, you can send FUCK token tips to their wallet. For example, your friend is brooding over his marital problems? Give him a FUCK or two and watch his smile brighten up. Thousands of FUCKs are given every minute. This is pretty much it.
