The Call Data Comrades are a 10K Ethscriptions Collection. Not NFTs, these are inscriptions! They are forever inscribed in the Call Data of the Ethereum L1.
We are here to start the renaissance of the Ethscriptions protocol and to bring attention to the awesome first movers in this space like the Mfpurrs, the Hyppocrites, the EthereumPhunks, Nakamingos and so many more...

There are a lot of easter eggs and allusions to highlights of the ethscription space in this collection. So prepare for an avalanche of nerdom and mind the gap between the blocks. But most of all consider becoming a Comrade, Comrade.

There is a place for everybody in Block City!
BEcome a comrade

The World

From Block City to the Drain Planes – get to know the home of the Comrades.
The Call Data Comrades live within the Call Data of the Ethereum Block Chain, in a realm called the Ether. A funky place full of history and heroes, but also full of dangers.

A long time ago the Ethernals witnessed the first block popping into existence and with it an angelic being, going by the name of Validator Rex.

The Ethernals created the Comrades after the image of VR, which in turn placed the first Block of which should become the home of the Comrades. The shining city on the Hill – Block City.

Even though Block Assembly Complex C137 is by far the least productive site, it is also by far the most pittoresque.
Which is why pictures of it are often used to recruit new comrades for the hard but lucrative work in the block assembly business.


Due to the lack of competent leadership at BAC C137 anyone here works barely if ever at all. So if you don’t have any ambitions, getting a job at BAC C137 is like winning the jackpot every day for the rest of your life.
The powerful technology that made Block City the epitome of freedom and self sovereignty also created the rotten fields of the Drain Plains

The Drain Plains
A place where evil lurks and one single wrong step can cost you everything.

This is the realm of the dreaded Pirate King and also that of the Rug Lord – a mysterious being that came over from the YONDER and seeks to rug everything. The Citizens of Block City are in a constant conflict with the Rug Lord and his four Henchmen of the Ablockalypse.

Tread lightly here and don’t listen to the whispers.

The yonder

Hidden from the world of the comrades another realm exists. It is called The Yonder.
While the Ether is a pretty funky plain of existence, the YONDER is a vast and mysterious realm full of strange beings.
The Yonder exists far beyond the Ether and not many Comrades were granted a peak behind the veil that separates these worlds from each other.
Sometimes the veil becomes thin, sometimes pathways that used to be hidden slide into one’s peripheral vision and cast a tempting and fateful invitation.
But there are also ways to open one’s mind to be able to see into this other world – if only for a short amount of time. It’s a peak both into the universe and into yourself at the same time. But only the strong minded should choose to do so.

Floorbagorb migration
Hidden pathways exist between these worlds and sometimes beings from the YONDER make their way over to the Ether.
Most of the times these beings are mere explorers, sometimes they just want to enjoy all these vibrant colors and the awesome beach parties, but sometimes they just want to cause trouble – like the mischievous Floorbagorbs.

Unfortunately these little buggers are the most common visitors from the YONDER. They can be a real pest at times.
At the time of the Comrades mint there are 6 Techno Lords from the YONDER currently vacationing in the Ether.

Unlike the Floorbagorbs or the Rug Lord and despite their grim looks these are actually pretty nice fellas – having a blast over here with all the colors and stuff.

Nonetheless the Ethernals don’t really dig their presence in their realm and they are more than willing to help you banish them from the Ether and send them back to their realm – the YONDER. But they will never be able to come back if you choose to do so.

In the real world this means you will be able to burn your Ethscriptions Techno Lord to get the matching Ordinal from the YONDER collection on Bitcoin.

Legends of block city

This is the elite of the elite of the Comrades.
The Genesis Block

The Genesis Block

And then there was the Genesis Block.

There are many speculations about how it came to be.
Some involve a super nerd from another dimension named Vitalik, which is what the Dexclesia claims.
Others involve wonderous sexual practices of the Ethernals.

Validator Rex

Validator Rex

Validator Rex came into existence with the Genesis Block. There was not a single block without this angelic Knight watching over his subordinates. 



He makes sure that everything stays in order and that every comrade can enjoy their blocks to the fullest extend. He laid the first block of what is now the shining city on the hill, Block City.

And he is the commander in chief of the powerful elite guard that is called the Adeptus Cuborum.


He is the light, he is the truth, he is consensus. And if you don’t agree with him you will live the rest of your blocks among the honorless heretics in the rotten wastelands that they call the Drain Plains. 
This also shows how merciful of a ruler he really is. Because if he wasn’t, he would just send you to his old friend 0xDEAD instead.
The Rug Lord

The Rug Lord

The Rug Lord is a being from the Yonder. Nobody knows how he was able to make his way into our world, but however he did that the mostly chaotic neutral beings from the Yonder are quite happy he’s gone. But now the citizens of Block City have to deal with him.

While others have their reasons to do evil, the Rug Lord does not. He does not just want to rug you, certain protocols or certain tokens. He doesn’t even want to rug for his own gainz. He just wants to rug EVERYTHING until there is nothing but darkness and silence.


He is destruction, he is death and everything that will never be. Even the most ruthless folks in Block City fall silent and look around nervously when his name is spoken. Which is why nobody ever speaks of him. Except for Jerry, the old nutjob from Block #80085, which is also why nobody likes Jerry.


Legend has it that if the Rug Lord is ever reunited with his 4 henchman, the Ablockalypse will start.
Ethernal Prime

Ethernal Prime

The Ethernals are mysterious beings of the Ether. They created the comrades after they witnessed the first block pop into existence.

Even though they usually don’t mingle in the matters of the mortals anymore or in any matters really, they show up from time to time to remind the comrades of how cool they are. They generally enjoy the company off the comrades – except for that of Default Comrade 08/16, they try to avoid her at all costs.
Ethernal Prime is the Boss of the Ethernals. Which is most likely because of his immaculate beard.

But whatever the reason the Comrades love to listen to his stories especially at beach parties when Prime starts talking about the time before the Blocks (after going 420 with his buddies Jonboy, Dickbutt and Peter the Imposter Captain.) Ethernal Prime denies to this day that they had anything to do with the creation of the Genesis Block and supports the claim of the Dexclesia that it must have been a being from another other Dimension called Vitalik. Though many think this is disinformation to distract from the weird mating rituals of the Ethernals.
The ethscriptions logo

what are eth­script­ions?

Some technical beep boop; ERROR: do not comprehend.
You don’t need to know any of this, but maybe you want to :)
The call data in Ethereum transaction is usually used to carry information that is needed to interact with smart contracts. But for Ethscriptions the call data has been highjacked for a much cooler usecase.

If you want a picture (or media of any kind really) to be stored in the Ethereum Call Data for all eternity and to be recognized as a valid inscription by the Ethscriptions protocol, the image data is firstly converted into a Base64-encoded data URI.

Which looks somewhat like this: 


“data:image/png;base64,iVBORw0KGgo....”

...and is subsequently transformed into hexadecimal format.

Which looks like this: 


“0x646174613a696d6167652f706e672c...”

This hex data string now represents the content to be inscribed in the ethereum call data. You can now simply paste this hex data string into the hex data field (not visible by default in MM) when you make a 0 ETH transaction to yourself or any other address. The receiver of this transaction will be recognized as the owner of this inscription.

Other than the Ordinals protocol the Ethscriptions protocol only recognizes the first inscription of any kind as valid. If the exact same hex data string is inscribed a second time the protocol will not index it as a valid Ethscription. There can’t be exact duplicates.

Don’t worry, you don’t need a calculator and you don’t really need to know any of this to play around with Inscription on Ethereum. There are tools that do all this for you and this is mostly happening in the background :)
We fell in love with the simplicity of inscription on Ethereum just like we fell in love with inscription on Bitcoin – Ordinals. And we feel that inscriptions, on whatever decentralized L1 chain they might be, have a bright future ahead of them.

Ethscription #0 from May 29th 2016

Which 7 years later became the inspiration for the iconic Mfpurrs collection
On May 29th 2016 the first picture was inscribed on the Ethereum Blockchain – long before the cumbersome name “Ethscriptions” came to be.

Only 11 inscriptions where made during the following 7 years until Tom Lehman (aka Middlemarch) developed the official Ethscriptions Protocol and went public with it in June 2023 with the mint of the Ethereum Punks, that now make up the biggest part of the first 10K inscriptions on Ethereum.

This protocol allows users to create and share digital artifacts, such as images, text, audio, etc. by inscribing data directly onto the chain.
Unlike NFTs, which often store metadata off-chain on third party servers, Ethscriptions eliminate third party risk by keeping the actual content directly on the Ethereum chain and are thus secured by one of the most decentralized data storage systems in existence.
