I made a working Bank in Minecraft 

A bank? Is this were all the diamonds are kept Mumbo? :-P

Mumbo went from being a cyclist to photographer and videographer to being a social minecrafter to being a filmmaker to being a cyclist to being a minecrafter to being a film-videographer and now an all in one big combo jumbo

"We can access Scar's bank account! This is awesome!" -MumboJumbo, 2023

I love how mumbo doesn’t even mention the fact that he filled scars bank account with coarse dirt and it wasn’t even a full shulker box of it 😂

I love how Mumbo wordlessly went to the lengths to depict his bank account as far richer than the others'.

After Sahara, potatoes have become the worst enemy of redstone contraptions for Mumbo and Iskall.

Nothing is more exciting than hearing how genuinely excited Mumbo gets playing with redstone 😀

The more I learn how to code the more I realize why I like redstone so much. The thought process and connections are crazy similar! The fact that I am making a career out of “adult serious” redstone is wild to me lol

I love how Mumbo is making this redstone project Grian-proof despite this being a private server with no Grian on it.

I love how Mumbo always makes overly complicated security systems with terrible passwords

I’ve been waiting and imagining this moment for a year ever since he made a ATM this will be useful for my city build later on. Thx mumbo!

2:45 “Mumbo gets curious, then disappointed about a shipwreck.”

Mumbo is back to his capitalistic ways I see. Honestly, a great way for him to warm up before resuming his role as the richest man in Hermitcraft again

Mumbo will clearly store his massive amount of diamonds in hermitcraft in this massive bank

Scar’s bank being course dirt makes a lot of sense actually

These are such random concepts no one would've thought for, except you. But it's execution by you is just so fun and your way of presentation, we all love it don't we? The silliness and just concept in general..... Working theatre? Giants did redstone? Working bank?

I love how Mumbo was able to learn how a 9 digit redstone combination lock works by just building one while my eyes glaze over and I'm at risk of blacking out if I stare at more than one repeater or comparator.

I long for this to make an appearance on a Hermit Craft episode. This could start a whole Bank Heist story arc for the hermit server. It would be pretty sweet.

Reminds me of when he made what was essentially a credit card system in hermit craft S7. I was so impressed by that.

So AMAZING to have Mumbo back!!! Big inspiration for my content!!

When you see real-life computing translated into Minecraft redstone, you really gain some appreciation for the people who originally designed such systems from scratch

I love how mumbo's first instinct when it comes to the combo lock is movable tile entities, and not another shulker selection system

this is the kinda of thing about redstone that fascinates me. I truly wish i understood redstone more so i could build something at least half as cool as this. Awesome idea Mumbo! I'm glad to see that you're feeling better and back in the swing of things

At some point I tried making this system, but didn't have enough knowledge and patience so I had to abandon this idea. What you did is incredible. Good job mumbo, as always.

This would be an incredible system to use in hermit craft decked out for everyone to keep their cards, maybe a cool project you could start back in the season with tango

seeing how excited and happy mumbo gets when his redstone projects actually works out just absolutely brightens my day right up. love this guy, and i will definitely not be trying to make this in my game, especially since i dont even know how a comparator works LMAO

in the lock system, you have to put in a non stackable to have enough power to lock the hopper, and the slimestone needs to be inverted at the top, and the piston observer chain has to be indirectly facing into the dropper so that it doesn't activate the surrounding dropper. Other than figuring all that out this is really easy to build.

Dear Mumbo - it feels so good to see you back here having fun! Your excitement was so much missed. Also - absolutely great work! I once learned simple redstoning and everything you show and explain sounds like "yeah, that makes sense!" - and then I've no idea what's going on but it works xD that's great.

Others have probably said this already, but I’ve got a possible workaround for the movable tile entities! Like have an extra hopper above and below the combination chest to load/drain the correct number of items depending on whose password is needed. Just use red coders or whatever it was that made Sahara work to select whose batch of items get put in each chest! It might be slower, but hey, it’s vanilla!

It feels like Mumbo is doing some R&D that could be incorporated into some sort of secure vault.

I was thinking "This would be awesome on my dream server!" ...Then you started using moveable tile entities. You know what, this server is a dream in my brain! I can add movable tile entities!

Man i'd love to see a full build around this ❤️

It’s great hearing Mumbo content with his redstone style and him being happy with the success of his build.

Hearing the excitement in Mumbo's voice when it works is the single greatest feeling on this planet

This is a throwback to one of the first mumbo videos I ever watched!

Scar's bank account: 9 stacks of coarse dirt Mumbo Jumbo: THIS IS AWESOME!

Instead of movable tile entities, you could have used composters and a redstone block, and made the ninth button input a signal strength of 15. The system would be almost the same.

I love how when accessing your bank account at the atm, it lights up a beacon telling everyone in the world who is accessing the bank at the time

Mumbo: "I'm chuffed to bits" Everyone: HE SAID THE THING! HE SAID THE THING!!!

0:26 as an English man I can confirm that mumbo is correct. These are what these ATM machines look like in England.

Instead of using the carpet mod for moveable tile entities you could dispense separate shulker boxes for each account that all have the different amounts for the combo. It might take up more room and be more difficult, but it could work in vanilla.

The Hermitcraft Season 6 reference in this video got a smile out of me. I should re-watch that whole saga. So much chaos in Season 6. It was amazing.

10:04 Scar's head will light up ? Is it just me or does that really sound dangerous

I absolutely love this video and the concept.

I spent the entire episode waiting for him to say "chuffed to bits." And Mumbo delivered, right at the end.

I love this idea - adding this to hermitcraft’s currency system would be interesting to see

Congratulations Mumbo, this is amazing!

i dont really play minecraft anymore, but its always fun to see a redstone builder building stuff... that works.

I love how mumbo shows the whole process of him figuring it out in his videos.

I don’t think I’ve ever seen him be this chuffed over something he’s made. You love to see it

Great job Mumbo! very cool!

That was awesome! You are a madman, or a genius, or both! A working bank suitable for survival... Wow!

You should put this in the next season of hermitcraft. I feel like this would make a great addition to the server and people would actually enjoy using this because it also gives the server a little bit more of that RPG vibe

For added security, use signed books as key cards.

6:48 Ooooh I know this one, it's great ! It's the one I used for an elevator in my latest base project ! Which I ended up never finishing... God darn it

I’ve literally watched this like 100 times I can’t get over how clever mumbo is

Sure, you could use an ender chest, but you miss out on the ability to give someone your bank card to withdraw something for you, as well as the spicy potential for a bank heist. Not to mention that this could be expanded to allow for multiple shulker boxes to be revealed, granting multiple chests worth of storage space that only you can access. Also I like how this is just Sahara all over again. Must've been nice going back to his roots after becoming the richest hermit on the server.

I love how mumbo’s slowly setting back into hermitcraft while hinting it in his videos :]

congrats brother.. this is def gonna be a game changer

Ooooooo! That is very cool. I can't do anything in red stone, but I sure do love seeing what you can do with red stone.

Hiya Mumbo! Great ending, sure the end chest is great. But I can see having a working bank in the shopping district all the same. Stuff happens silk pickaxes get misplaced, and sometimes a hermit forgets an end chest in their shop. I've definitely seen that several times. Don't forget to add a bank fee. You did great adding the combinations into access the accounts. Thank you Mumbo for this video. Sharing your joy in you red stone build!

To save the individual combination in vanilla, you probably could set a row of filtered hoppers that lead to each combo container with a locked hopper under it. They would filter 4 stackable items (stacks of 16, like enderpearls), and use 4 different items, so they always go to the correct digit, then return the contents via water streams from unlocking the hopper below the combination container back to a single chest assigned to that player. For the combination containers, it'd just take a hopper as the container so it would take the fewest stackable items to assign the 1-9.

Whenever I watch one of your videos mumbo, I'm like " ummmmm, what does that do? what does this do?" And I love it!!!

i love that because i usually only use repeaters and compareters to make redstone the 4 digit code from this video looks much more logical then the one of the other video XD it just locks it if its right if its wrong it sends a signal to all others to unlock everything.

Mumbo obviously needs somewhere to store all of this diamonds, everyone knows he's the richest hermit.

I love that Mumbo referenced the Sahara potato incident. Do NOT let Grian near this bank or history may repeat itself.

Just hearing the dude bumble over his own words and decisions is awesome and funny. I’m glad he’s enjoying this redstone chaos 😅

Why is EVERYTHING you do amazing!?!?

11:39 it says "I got nothing" for 2 frames

2:04 Cough **Grian** Cough

Wow this is genuinely incredible.

Cool video mumbo! :) Could you implement that in a world without movable chests by having a shulker box with 4 different objects and an amount from 1 to 9 for each? You select the right shulker box upon reading of the card and empty it for impulse filters to place place the correct object to the correct chest therefor setting the 4 digits code. And when you close the account, you first disable the code reading mechanism, then empty the chests using a minecraft hopper that would put everything back into each player's code shulker in the right order?

I do think there’s a way to bypass the pushable chests dilemma, although it would be stupidly bulky... The combination circuit is incredibly flat. So flat you could probably stack them one-atop-another. And seeing how the selection system works, I think you could easily rewire it so that whoever you pick reroutes the circuit to another combination lock. Thats just my take thought. Excellent build!

Ender chests can only hold 27 shulker boxes, this is #28 ;) Which on that note, you could also have an ender chest in your bank, maybe even use colors and textures to make it feel like a massive one.

This thing is just a very big, complicated and less secure ended chest. I love it.

It's Sahara all over again! That was a pretty awesome build.

I'm only 3 minutes in and I'm DYING LAUGHING I have missed these videos so much! Im glad you're back to making videos, Mumbo! So excited to see what you do next!

6:31 Love how Crafty literally made an entire video roasting Mumbo, then Mumbo mentions him like some random guy. It's like that '"I feel bad for you""I don't think about you at all"' meme.

I love how accurate each of the chests were.

Great to see you enjoying yourself again Mumbo

With all this combination locks and banks I feel like he’s preparing to keep Grian out of his vaults. The k.g.o.o.m.r is getting an upgrade.

Top tier banker

I would love to see videos like this and others remade now that the copper bulb is a thing! I wonder how much smaller it could be!

Now you have something to do with that vault you built in Hermitcraft. Welcome to the Bank of Mumbo!

Okay, but after watching Grian's episode and realizing Mumbo's been gone since episode five... and how he's put his time into other Minecraft videos... this one seems more than a coincidence... Bank? His Vault base? Is this a return? Will we see this implicated in his base? The excitement!

“We don’t want a jacket potato ruining the whole system” Yes, we all know what you mean mumbo. *Season 6 flashbacks*

This video made me incredibly happy :)

I like your funny words magic man Fr though the mount of brain that goes into these videos is insane, they’re so entertaining and so cool, even if I only understand 2% of what’s happening

"because otherwise a simple jacket potato could break the entire system" I understood that reference.

10:38 I just started imagining Mumbo doing a tutorial on how to hack bank accounts and it's honestly hillarious

A better ATM could be done using several keys: Take 10 hoppers (any number works, but 10 works fine for this). Give every person ceiling(log([AMOUNT OF USERS])) keys. For example, a bank with 240 customers will have 4 keys. Then input each key one at a time, store the output and use it to access an inventory. This is an improvement to the original design because the amount of space per customer grows logarithmically, which is amazing compared to the linear growth of the original design. However, the system is less user friendly compared to Mumbo's design. Edit: Another commenter mentioned that jukeboxes can detect which disc is being played. This can reduce the size of the system drastically :D Also, the design could be really user friendly by using shulker boxes as cards instead of individual cards. In that case, with both the jukebox and shulker box you could have 5.68⋅10³¹ total users. Another thing to mention is that the space will actually be O(n⋅log[n]) because of the storage for the actual items! Right now, another improvement could be having a central storage and a memory for each user, but then that takes us back to Mumbo's design with a hard wire for each customer. Maybe instead, you could have each shulker box represent some amount of diamonds (say 100 stacks), which could be used for bulk purchases. The shulker box would then be just a security system instead of a memory system. Oh hey would you look at that, I just made the minecraft equivalent of a dollar bill!

I was just watching some older redstone videos, and I think we need more world downloads from you. I would love to rebuild some security locks and doors, but if there is no tutorial or world download, I simply can't

10:40 “we can access scars bank account” -mumbo

I started watching these types of videos before I ever watched an episode of Hermitcraft from Mumbo. Really super happy to see them back and you having fun. Always really enjoyed these a lot. Actually started my redstone adventure. I’m very glad you seem to be having fun. I enjoy Hermitcraft as well but I’ve always enjoyed watching you just create whatever you think is fun, funny or cool.

Love it!

the minopoly man... u now ruind my mind forever :D

I remember I tried to make a redstone bank years ago (on an Xbox 360 super flat world). It had a keycard reader and used minecart chests as the individual bank accounts. I think I got it to work. But this one you created definitely takes the cake. Great video

I'm genuinely amazed at how this works! I really hope we see this kind of thing implemented with your vault when you return to Hermitcraft!

Mumbo has got to be the best redstone engineer I have ever seen

Mumbo, I am glad you still enjoy minecraft. I used to love this game, but I quit after repeatedly dying when trying to enter the nether to a zombie wearing my full enchanted diamond armor. He would kill me before I could even see him. It was such a horrible experience I ended quitting minecraft. But I enjoy watching you build these goofy contraptions.
