29:46 Even after obtaining illegal blocks, build insane machines in survival, and exploiting the game in every single way, the cobblestone generator is still truly the hardest thing to build.
I can confirm that I have done it in survival
@@LHS_Shadow hax
@@LHS_Shadow true indeed i can successfully build an iron farm but still failed making it multiple times during my survival
at first i expected it to work because i thought lava flowed faster in the nether but i am not sure
@@xiutecuhtli15 If the lava flowed first it would convert the water source into stone instead
the irony of building an incredibly complex machine to generate water in the nether, and then using it to fail to make a cobble generator, is not lost on me.

You know this feat is insane when it takes over 30 minutes to give a bare bones explanation of how it works
You have no idea how much of an oversimplification this was. This was nothing compared to what actually went into the research part of this project
@@JKM115 years of research after all
@@JKM115 you're right. We don't.
and on bedrock you could just use a simple command glitch and get any block you wanted 🫠
@MrToast the term is typically bear bones.
The whole thing with creating illegal blocks through specific "recipes" sounds like alchemy.
thats next level crafting
It's very similar to nuclear scientists trying to make the synthetic elements that decay too fast. Like Oganesson being element 118, was made by smashing element 20 and 98 repeatedly until it happened. Before that, they also tried with element 82 and 36, since that also added to 118.
Yeah they're essentially nuclear scientists except instead of atoms, it's the binary code they're smashing together
@@thepeanuts55 Yeah, that's an even better description for it. Minecraft's own nuclear physics.
I prefer alchemy. Fits with minecrafts theme better
@@thepeanuts55 Why not 117 and 1 or 116 and 2 or 115 and 3 or 114 and 4 or 113 and 5 or 112 and 6 or any other combination of x and y where x+y =118?
Very cool that the technology of using data corruption on blocks in 1.12 (and even pre-1.12) continued on despite the numerous updates since then. Congrats on this achievement. Super cool to see.
hi cub
(loved total chaos btw)
hi cub!
Hi
Hi Cub!
Yes cub
Props to JKM with the clear and simple explanation. Even without having any knowledge how minecraft is coded, I was still able to follow the logic. :)
Thank you!
and for telling the other guy to stop interrupting 💀
I watched his video on it and he sounded so arrogant and cocky. Not saying he is arrogant, but few times he seemed so.
@@vedranculjak8262 well to be fair this is his expertise
‘clap’, myren is the one who was trying to clarify the parts of JKM’s explanation that were completely oversimplified to the point of hardly making sense. I recommend you watch Myren Eario’s entire series on the falling block project. He has the complete right to interrupt.
The moment I heard “multithreading” I knew we were in for a wild ride.
concurrency is both the most basic and some of the most complex computing concepts. :) Love seeing exploits like this
I don't understand why mojang decided to create multithreading for some reason whenever a player place a glassblock. I guess, Mojang work for SciCraft
@@octobsession3061 lighting is super processor expensive, as is transparency. Putting them on seperate threads makes the main game thread run smoother. Stained specifically interacts with beacon beams, so a bunch of beacons plus some glass creates a bunch of updates. If it wasn't multithreaded, it could cause more lag since the glass has to look for beacons below it every time it's placed/moved/updated. A lag spike every time glass was updated would be really inconvenient, so it's offloaded to a different thread
Why it ends up forcing the main game itself to split threads, that's probably just a really weird bug that nobody could be expected to notice since it's such an edge case that it would never be tested
a good way to handle this is a hashmap based poi system, where a glass block can retrieve the highest beacon under it in constant time. what mojang did falls under the bad way to handle this category.
It's a shame you can't use them outside of creative mode, I guess Mojang accounted for SciCraft magic
More to account for mixed mode servers, like having a spawn area with command blocks to navigate new survival players to other locations
Well in some cases on some servers using cheats or backdooring the server players managed to get the command blocks, it wouldnt be good if they could interact with them.
@@O5MO It was just proven that commandblocks were used by a backdooring individual on 2b2t
@@sjege That individual likely had permissions themselves through the backdoor access.
@@theencolony5595 or just maps, if a survival map has tons of command blocks, and somehow a player finds them, well either they can change into creative and modify it themselves, or they arent supposed to be changing them
This is the most incredible crossover event in history. I loved the Inheritance saga and I read the whole stack of books in middle school. I have a deep appreciation for that story and when I heard ilmango say Christopher Paolini was on this tour, I had to doubt whether he meant the actual author. So cool to see him in a technical minecraft video, the fact that I share a passion with one of my favorite authors just made my whole day.
You just described exactly what I was feeling, I've read the Inheritance saga countless times and never in my wildest dreams would I ever imagine such a crossover!
Same here bro. I was like no way it’s the same dude. And it was lmao
Same
Same bro i read it i thought this is a dream and will never happen but it's real
Before even starting I had to check the comments for this. What a crossover lmao
It's a shame Myron is so hard to understand. He seems very knowledgeable and was seemingly adding a lot to the conversation.
Yep, I wish the volume was more high for him, I barely understood him.
Also it was a little bit annoying when he interrupted, but I recon he was just super excited to talk about the technicalities,
I used subtitles for him
@@ttineyastrana4353 That was really helpful for me, I’m really glad I used it to get all the interesting things he was saying. Especially that part about using water to create weaponized dogs, cool stuff!
@@ttineyastrana4353 auto generated text was so surprisingly helpful for once
@@DvH_2 mood
About time Myren gets a new mic lmao, the guy is so knowledgeable and gives alot of good information, but i could barely hear him, had to turn on subtitles, haha. Also props to JKM, don't think you can explain the process or how it works any better than that considering how complicated the mechanics of it is.
his accent also does not help
Agree, I hope myren get his new mic soon. And JKM actually give full explanation and comprehensible by non programmer/redstone expert
>”We’re gonna condense it down to about half an hour”
>About an hour
half an hour is just the explanation 😆
Just blows my mind that they hacked the game from inside three of four times over to create universal fast travel. The devs must be having nightmares over this group.
Some of this group are devs lmao
It's amazing how much control over the game redstone gives you.
@@JakeWolven they've infiltrated mojang lmao

It was awesome😂😂
You know what. I'm not surprised. I'm convinced you can do literally anything in Minecraft. You actually know the game's code better than all Mojang, like, what is this
Now they just gotta find some way to create a command block with specific NBT data injected into it, to make them execute commands. It sounds absolutely impossible, but the Scicraft guys obviously aren’t concerned with whether things are possible or not
@@zeppie_ and whatever they do absolutely can NOT be easily understood or uncomplicated in the slightest
this is so cool damn. the fact that you can so reliably corrupt certain pieces of block data in a certain way, with just survival mechanics, is mind boggling
This is my favorite series and now we get a clear explanation for the falling block gimmick! TYSM!
Love the fact that illegal blocks have their own 'recipes'.
Edit: Added quote marks :)
Well theyre not actual recipies. Theyre recipies that are needed for the exploit but its not actually in the game.
Yeah, calling it a "recipe is clever way of describing their way of corrupting the bits of two different blocks to combine together
@@hieatus1039 you just said youself they are recipes? It most definately is in the game also, since they just showed it in this video.
@@hieatus1039 Well, lets call it "alchemy recipes")
I love the way they were able to get them. It makes it feel like a mod even though it’s all in survival. Falling block recipes are so cool
This is like a Minecraft research team, seeing how in depth this goes into the structure of the game itself
I really enjoyed this explanation. Kinda makes the other videos I’ve seen about the falling block exploit thingy make a tiny bit more sense. Who would have known this years ago. So glad there are individuals like you guys to dig this deep into the game we all love. Very well done!!!
"The server didn't crash, that's a weird result, but i'll accept it"
Wow I'm amazed that Christopher Paolini was on this tour, his book series is the whole inspiration for my name and I've kept this name for over a decade (and yes I know it's spelled wrong). I loved all of his books and my Minecraft skin is even Eragon, just amazing that he's there.
This is simultaneously the coolest and most cursed thing I’ve seen in a long time.
I've been searching for this explaination ever since this series got rebooted. Thanks!!!
Next episode: alright guys we've figured out how to use falling blocks to insert commands into command blocks in survival, we are now op and able to access creative in survival
if you look in the chat at 3:47 your able to see that someone was switching to creative mode(❁´◡`❁)
Command blocks won't work in a server with commands disabled
@@marcovalle9925 hmm, we'll have to get the command block to change that then
They said in the video that they wouldn't want to use such an exploit even if they found one. Very understandable as that would just ruin the whole purpose of the server being in survival.
this is so funny
I absolutely LOVE the servertour
I love how scicraft put water in the nether…. And then failed to make a cobblestone generator
Thanks for the awesome content!! I know these longer videos take a massive amount of editing and time. I really appreciate it!!
this is the nerdiest thing I've ever watched and I absolutely love it
so the way you get creative items in survival minecraft is *literally* alchemy. Transmute lava into water by adding some anvil while doing some ritual with a massive amounts of observers and beacons, then add something else to that while doing stuff with a piston and presto.
They literally distort space and time to reach their goals 🤯
props to the guys explaining. they did a very good job breaking done something as complex as this, even if they simplified it a lot.
You know, I'm not even surprised at this point.
I knew it was gonna happen at some point. Madlads finnaly did it
He is not the first one, go check elrichmc susrvival video
Now we know the reason that they left the server on 1.12 for so long. They were hinting at something like this for so long.
@@arturoperezrueda4110 They were the first ones to get all the illegal blocks. ElRichMC only has bedrock for now, and that happened later.
While this video was uploaded later than Rich's video, this tour happened some time ago, and the project itself happened way before Rich started his own project (idk how earlier, but on Twitter you can find tweets about it). We know Rich started not too long ago thanks to his tweet about never using a Plan C.
Said that, what Rich did is still hella impressive cuz it was Survival Singleplayer
So stoked for this crossover!! :D The Inheritance books were a series that majorly defined my childhood.
i love how these guys are like 'so basically,' and then start speaking enchantment table
I highly recommend you all watch Myren Eario’s entire series on the falling block project. Despite the implication of this server tour explanation being the ‘simplified’ one, the explanation on Myrens channel is 1000 times simpler and more coherent than this one. There is a proper full script and it builds up each concept right from the most basic level of minecraft understanding, unlike the bombardment of specialised vocab in this video.
Very entertaining tour nonetheless though!
Bro when he said “this is the most advanced thing you can do in this game” I just laughed because legitimately this might be more advanced than coding and making the game itself
This ain't minecraft, this is a computer science lecture
After seeing the setup required in the stronghold for generating falling end portals, I'm convinced no one could put together a better group of people to solve these problems. Also major props for actually being able to present this in a way that's "easy" to understand, truly masters of Minecraft.
I literaly just finished watching the last Sci-Craft video.
As someone with an in-depth programming background in C, this actually makes lots of sense! Thanks so much for the explanation! :)
Good thing that you made this clearer in a video title. A lot of people missed this in the last video and were irritated
This insane setup reminds of those really weird ACE sequences people would do in older games whether it would be for speedrunning or to pull off something unexpected
i think they'll be able to find a survival ace exploit eventually, assuming it's at all possible
Next we built a machine that can automatically record, edit, and upload our Minecraft videos by itself
"We created the singularity in Minecraft, follow the links in the description, if you too want to join."
Next video: accessing the creative menu in survival
come on dude, how can I get fascinated only via reading the title? scicraft never ceases to amaze me
It still amazes me how much you guys are able to bend the game sideways to get what you want
You got my favorite author in there! Awesome!
I feel like they could have explained this a lot faster and a little more structured, but this way it had a lot of SciCraft character ;D
Great vid, very interesting. Thank you
This was actually something I always wanted somebody to do for a while
Blockstate corrupting sounds like a completely new crafting system! This should actually be used in a mod or something
My toxic trait is thinking I could do this too
Amazing project!
What amazes me most is that most people in the world (or even in the Minecraft community) cannot begin to understand to what extent this project is intricate, delicate and complex.
This is real science and engineering happening in a game. There are not many "real-world" projects that have this level of intricacy.
Scicraft is a poem.
Literally playing god
Wow, you guys found and took advantage of a race condition. You're literally using expert-level cybersecurity techniques to get otherwise-inaccessible blocks in Minecraft.
thanks. i was thinking what we were doing was kinda related to pen testing or something like that
you guys might not have an idea of who elrich is! he might be the best (at least one of the best) vanilla MC players in the spanish community, which is hugeeee. there is a massive hispanic community you guys might not be aware of.
and having elrichmc in scicraft is one of the best and unexpected collabs Ive seen in MC!
Lo conocen mejor que tú xd
@@saidtorres3 lo decia por las dudas. No miro mucho scicraft. Pero vi muchos streamers hablando de ibai como si no conocieran la comunidad de habla hispana. Supuse que en mc seria igual, mala mia.
Igual los de scicraft tal vez si lo conozcan, pero hablo a viewers que consumen MC en ingles.
I saw Jkm's video on it, and new this was coming, great video ilmango, can't wait for more.
remember guys, this was the *short* explanation
It's funny you brought ElRichMC, since he was able to do the same thing in his Survival Singleplayer not so long ago
damn what a coincidence
He didn't do the same. He did used the update supression and the population exploits for creating a barrier block
And used save state exploit + bedrock breaking to create 127 bedrock portals in the end.
So, he didn't do block corruption neither he obtained falling entities. And I don't think he plans on start duping things so the falling blocks wouldn't be as usefull for him
@@miguelangelmartinezcasado8935 nonono, you're confusing the bedrock tower, which was last year, which the last episode, where he got the falling bedrock on vanilla singleplayer and also placed a command block using these same exploits
@@TheA_Gamer554 I didn't saw that one, my bad
Mortal minds: "The universe is so mysterious. How could god make something out of nothing?"
SciCraft: ***blockstate corruption***
these guys are so epic, they even get lag to do work for them
The single vs multi thread explanation was great!
I knew it was possible.
Hopefully this means in some way or another, pre programmed NBT command blocks are possible
I guess since they used a data race to corrupt blocks it would be possible to for example combine two blocks with nbt into one with a useful nbt, but considering they had to replace one block instantly with another, it seems like theres no such block pair for nbt stuff.
NBT manipulation does exist, but is very limited. It is required to get the player head.
I don't think there's any way to do it. You would have to replace the NBT of the falling block with the NBT of a valid command, and there's no way to add arbitrary NBT to anything unless you already have access to commands.
Also, block items don't have NBT, so if there IS a way to do it, it would have to happen after you place the command block and it generates its tile entity
@@magnuswright5572 Unless you just don't use this method. Somehow manipulating items into existence maybe through ids of items dropped by mobs or something.
Also, you can summon a falling black entity command block with NBT, just generating anything like that to even begin to have a recipe for it could be hard. That's assuming the NBT of any kind survives or is meaningful
Super interesting video. I was always under the impression that pretty much everything runs in one thread but I'm surprised to see that you can get some interesting interaction between multiple.
This was very well explained and so genious thanks...
I really would love to hear the reactions from devs like notch and jeb to stuff like this being explained.
why do I feel like their gonna figure out some way to corrupt/swap NBT data and get a command block and gm c's everyone?
Lool
I mean u can swap tile entities nbt data with some werid exploiting. But u cant really do it.
@@TFirsty I hope to see it lol, maybe something to do with books or signs would do the trick idk
hows car ball been? i played with u once like 4y ago and it was dope. was even cooler to notice we both enjoy programming
@@Elliot.2591 eey, tbh dont really play much rl anymore lol, mostly minecarft and programming are my pasttimes
these guys went beyond minecraft, this is BITcrafting
That’s an awesome explanation of multithreaded processing, I’ll go a little bit more in detail.
Most computer CPU’s these days have multiple cores, and what this means is that it essentially has multiple CPU’s in one. The motherboard connects to it in the same way but under the hood there are multiple single core processors that can all do things separately at the same time. Classically, code is executed line by line in a linear fashion. The computer executes line one, then line two, then three, etc. always in linear order. With multithreaded programming, you can actually specify a chunk of code or “function” to be handled by a separate thread. While the main thread is doing it’s own thing, the other thread can run at the same time on a different core. If your computer can’t process the necessary number of threads then it’ll sorta pause some of them for a bit, run a few lines on the first threads, then switch to processing the paused ones, and go back and forth. In well written multithreaded code, we set up locks on certain pieces of information that multiple threads might want to access. If two threads want to access the same piece of information simultaneously, there’s a chance they don’t work together correctly and we get an incorrect end state. For example, we have some number x=0 and each thread is supposed to take that number and add 1 to it. If we have 2 threads, naturally we’d expect the end to be x=2, but if both threads work at the same time then they both see x=0 and both change it to x=1 at the same time, so we don’t get x=2. By “locking” that value when one thread is using it and forcing the other threads to wait for it to “unlock” we get a more linear style of code. In the case of Minecraft, it wasn’t coded to be multithreaded so shouldn’t be facing this issue of two threads changing data at the same time, but they’ve found a way to force the computer to handle the game in multiple threads thus causing an error because there was no locking system put in place.
what an incredible creation.
my head hurts.

Wow, yesterday I have just finished reading Inheritance and now there is a video with Christopher Paolini himself 😅
I just heard Paolinis name and Im instantly hooked. The Inheritance series is my favourite bookseries
Normal redstone builds: “don’t touch that! You’ll break it!”
Scicraft redstone builds: “don’t walk into that chunk you’ll break the server!”
Can we donate money to get Myren a better mic?
LOL, check the discord on how many times we complain about that and offered him something to get a better mic :D* LOOL love myren
@@apPaulpie he is so knowledgeable I wish I could understand what he says ;-;
I don’t think it’s his mic, he just needs to talk slower
@@fontajo It's the mic plus poor articulation (especially really bad rhotacism). The speed doesn't help, but slowing down wouldn't be a sufficient fix on its own.
Holy moly, is that ElRichMc?
omg i have been wondering this for the past week thanks for making a video lol
I saw multiple comments earlier about Sci-Craft will able to obtain command block in survival.
I got big smile on my face after seeing title 😀
Next up:“how we created a new account for free in survival scicraft”
They basically used quantum mechanics in Minecraft 💀
6:30
Christopher Paolini x ilmango? That's a crossover I don't think I ever would've seen coming. What a pleasant surprise!
This is interesting, it feels like I am in my Embedded System course in my uni again lmao
Congratulations again to Mr. ElRichMC for being the first person to obtain bedrock in Survival Singleplayer. Man is a legend
many people got it before him with the end gateway method like 2 years ago
Incredible, someone actually laughed at one of Ragou's jokes
prolly not laughing a literal sense, more like "laughing" to be polite i guess :3
okay this is absolutely nuts but somehow I feel like I'm actually kinda getting it. particularly with the "copy one part of the binary id and replace it on another" part and then the 21:02 explanation of "it's falling for a second and we spam observers so it updates in that split second and therefore changes" actually makes sense. I'm probably missing something else entirely but overall, it makes sense.
I am programmer, and it brings more questions than answers. In modern CPUs copying byte is an atomic operation, 2 threads working at the same time cannot corrupt byte. They must be simplified explanation a lot.
this is like a lecture I love it
Honey a new scicraft video dropped , no shopping
wow that 1 guy really loves stepping on people when they are trying to talk.
idk why but i found it so funny when you started spectating jkm at 6:09
I’d like to think that there is a group of friends in a type 3 civ, and they are doing this type of stuff with their own solar system. Creating mini black holes, zero point energy, quark foam, anti gravity. They’ve figured out the source code
Lovely that ElRichMC helped you in this! it's amazing see that people is giving the attention he deserves.

He was just invited to the server for a tour.

You could also throw a ender pearl diagonally through a nether portal being in the nether to teleport to the overworld coordinates where the ender pearl would land but be teleported in the nether effectively also teleporting to the coordinates times 8. If repeated multiple times you could also teleport anywhere on the map. Idk if it still is possible in newer versions. I thin I found out in 1.7 and 1.12 was the last time I tried.
oh damn that’s so much easier
It was patched in 1.12.2, and that's unfortunately the version they're playing.
Christopher Paolini?? I absolutely loved his books, but never knew he would be a guest in a Scicraft video. A surprise certainly, but a welcome one :)
Beautiful. The pinnacle of Minecraft inovation.
Y'all have the biggest brains ever holy shiiii how do you figure this out is beyond me. I wonder what Mojang thinks of your exploits.
Side note: I could barely understand what Myren was saying, idk if its his mic or something but I missed a lot of his galaxy brain explanations.
No, thats his mic
Yeah i could not understand most of it unfortunately
Yea I didn't understand him at all
@@O5MO well.... its mostly myren. he talks like that for forever and it is just a very unlucky mixture of voice composition, speech specifics, accent and microphone. at some point you get used to it, similar to how you start to understand loudspeaker speech in any kind of industry. ;)
Because they are programmers. They don't figure out in-game, they look at the decompiled source code and figure bugs like race condition, pointer exploits, etc.
grande Rich
These guys blow my mind every time they upload
"/fill a perimeter" has to be one of my favourite commands
