1024000^2 Blocks, 2B2T Minecraft Server World Download Project, and Discoveries
- jetbalsa 5mo agoAh, The 4chan of Minecraft servers, a silly place.
- Tiberium 5mo ago2B2T really has an extremely interesting and long history, and some of the most interesting exploits/security vulnerabilities found just for it, for example https://2b2t.miraheze.org/wiki/Nocom https://2b2t.miraheze.org/wiki/Nocom where the attackers had a blunt server DoS and through it influenced the server owner to report it to PaperMC, and the fix for the DoS gave them ability to track other players just as they had hoped. > In July 2018, 0x22 and Babbaj created a coordinate exploit, using the groundwork laid out in the lag exploit. The two theorized that, if the server didn't return a response for unloaded chunks, but returned a response for loaded chunks, the rough location of players in 2b2t could be approximated. However, prplz's patch returned a response regardless of whether a chunk was loaded or unloaded, requiring a second patch to Paper that would only return a response if the chunk was loaded. > Knowing that the issue would be resolved if Hausemaster reported it to Paper, likely through the method they laid out, 0x22 and Babbaj began intentionally, repeatedly, and blatantly sending CPacketPlayerDigging packets, causing the Paper watchdog process to output a stack trace, which included the line added by prplz.
- DefineOutside 5mo agoPeople have also tried to create merge requests into my plugin to reintroduce the issue into 2B2T. https://github.com/GrimAnticheat/Grim/pull/1131 https://github.com/GrimAnticheat/Grim/pull/1131
- bstsb 5mo agothat is quite funny, tbf. looks like the person who opened is friends with eva, a member of "server scanning inc" [1] so they thought it was worth a shot [1] https://eva.ac/ https://eva.ac/
- sterlind 5mo agoand then once they had the primitive, they used a compressed sensing algorithm or HMM of some kind to create a live player map. truly APT-level tradecraft.
- skerit 5mo ago2b2t is so interesting. It is a toxic place, yet you can find really nice things, builds, messages, ... It's fascinating.
- lanyard-textile 5mo agoThe highways especially. You'd think they'd be completely dysfunctional in a place like this.
- somewhatgoated 5mo agoThey get griefed once in a while but the highway builders have pretty amazing automation these days so it’s not only very boring to grief they will also almost instantly be repaired.
- DANmode 5mo ago> the highway builders have pretty amazing automation these days Great, now I have to study Minecraft to learn about human tendencies in anarchist societies?!
- komali2 5mo agoMy buddy and I used to plant shitloads of melon farms there. The idea was, anything could happen, but at least you won't starve.
- sciencejerk 5mo agoWith severe weaponized autism, the help of several people involved, thousands of dollars spent, and countless hours wasted, we present you the largest world download project ever Never underestimate the power of severe weaponized autism!
- elmean 5mo agoreal <3
- Netcob 5mo agoI have a theory that the modern world would not exist without it.
- plazmatic 5mo ago[dead]
- korse 5mo ago>Yeah and we'd be better off. The modern world is quantifiably worse than the world we had even 10 years ago. That includes everything in software development and computer science. Rather than killing this comment, how about we discuss quantification? I actually feel this way too but do not talk about it too much and sort of boil it down to a combination of advancing in age + yelling at clouds and "Stop putting computers in all my stuff!". Can we reliably quantify that "weaponized autism", i.e. the aggressive monetization of nerds by capital to squeeze profit out of every possible corner of society (as I interpret it in a broad sense), is making things worse. Is it damaging the economy for most people? Making people less happy? Decreasing net social mobility or discrimination? Lowering life expectancy?
- FrustratedMonky 5mo ago-> "monetization of nerds by capital to squeeze profit " Note. In case this is read incorrectly. For the most part the nerds are not profiting. The nerds are sitting hunched over their desk being fed coffee from a feeding tube, to keep them happy while the owners make money. And. To be more sad, these days you can't even get free coffee. Being fed free coffee and donuts, while others profit from us, is considered the golden age of computing. We loved our cozy cells, not so much these more uncomfortable ones.
- zimpenfish 5mo agohttps://www.youtube.com/watch?v=HDyze1YlOrI https://www.youtube.com/watch?v=HDyze1YlOrI is a good explanation of what they did
- pizzathyme 5mo agoMaybe a dumb question but since 2B2T (as I understand it) is a single instance of everyone modifying it to their heart's content, why does the download look like the standard biomes of a fresh minecraft map?
- jamilton 5mo agoYou gotta zoom into the center to see the main chaos. And if you zoom in elsewhere, you can see all the generation differences from different versions of the game.
- nom 5mo agoBesides the spawn area, most blocks have never been touched. It's a lot of blocks.
- lanyard-textile 5mo agoThe world is mind bogglingly big; as are most minecraft worlds, but this one especially. People sprawl far to prevent PvP encounters.
- aeyes 5mo agoIt is running on a single machine so the player count is relatively low. Today the limit is ~1500 concurrent players but it used to be much lower. And of the players online probably half are bots which don't build. The map is 30Mx30M blocks so outside of the very center you'll not see that much player activity. DonutSMP is the largest Minecraft server today, the overworld is 225,000x225,000 blocks and the map is modified wherever you look.
- wongarsu 5mo agoAnd because destroying other's builds is allowed most of the impressive builds are hidden in the middle of nowhere. Building within 50k blocks of spawn comes with the expectation that it might quickly turn into a crater or lava cast
- exploraz 5mo ago> Today the limit is ~1500 concurrent players The server have a pretty long non-priority player queue wait time with most of ~1500 you mentioned waiting in the queue (about 2/3 of them), even hitting two days last time I read it somewhere. > And of the players online probably half are bots which don't build. which might be why the queue wait time went insane over the recent years.
- nom 5mo agoThis was kept completely secret, so three days ago a separate group released their 200k² world download. https://www.reddit.com/r/2b2t_Uncensored/comments/1tefffd/introducing_2b2torg_200k%C2%B2_spawn_download_2026/ https://www.reddit.com/r/2b2t_Uncensored/comments/1tefffd/in... Ups.
- z3t4 5mo agoSomeone please create a google-map like view service so that I don't have to download the entire dataset.
- exploraz 5mo agoIt's linked at the GitHub README post.
- greggh 5mo ago2b2t Place is exactly that. https://2b2t.place https://2b2t.place
- Helmut10001 5mo agoIt is not possible to zoom in, as far as I can see (mobile, but tested desktop). [Edit] This allows zooming [1]. [1]: https://2b2tatlas.com/map https://2b2tatlas.com/map
- lanyard-textile 5mo agoFor those who don't know: 2b2t is a famous minecraft server known for its true "anarchy" configuration. You can do absolutely anything on it. Modded client, x-raying, item duplication. There are no area protections. PvP enabled. It is difficult to leave spawn :)
- skerit 5mo agoYou can use a modded client, everyone does, but there _are_ some protections. So you can get kicked, you just won't get banned.
- lanyard-textile 5mo agoI hand waved the details for simplicity, you're correct. Egregious bugs like item dupes are also patched; but while they last, they're allowed.
- lftl 5mo ago> It is difficult to leave spawn :) I know 2b2t is old enough to have had many different eras, but when I heard about and checked it out in 2018, the spawn was barren, of course, but I had no problem leaving and surviving out to a pretty far distance to build a little base.
- tapper 5mo agoThanks for the info. I was just about to post as a old fuddy-duddy WTF is this. lol
- Phelinofist 5mo agoIt is also the oldest anarchy server in Minecraft
- DaSHacka 5mo agohome to the dastardly popbob, minecraft's most notorious troll
- MattCruikshank 5mo agoI'm so continuously confused why Minecraft doesn't have a show-off mode where a team of people can build something, and then someone else can spectate it, without causing undue server load. I should be able to give you a URL to some location, and when you click it, it opens up Minecraft, streams the blocks, and you're viewing it. minecraft://server/loc?w=0&x=0&y=0&z=0 w is the overworld, nether, end, etc. And if you want to set up a server where you and your friends can interact with each other and make edits, the server should be able to stream blocks from some backing server, but copy-on-write them to your own local storage. How is this not a thing? If you want to be really awesome, set it up like bittorrent, where you can share the load, so the central server isn't hammered. And if bittorrent doesn't really work as a model, then set it up so that "downloader pays" for bandwidth, plus a small royalty for the creator. As a downloader, I get to set up rate limits, etc, to not accidentally spend more than I want to, etc. This whole 2b2t would cost $2,111.04 to download from AWS, if I'm doing the math right. But that's a trillion blocks. You don't need a trillion blocks to enjoy flying around some awesome maps.
- Rohansi 5mo ago> I should be able to give you a URL to some location, and when you click it, it opens up Minecraft, streams the blocks, and you're viewing it. > minecraft://server/loc?w=0&x=0&y=0&z=0 Probably no real reason why not... but I think it'd make more sense to take a snapshot, upload, and then have it viewable on the web. > And if you want to set up a server where you and your friends can interact with each other and make edits, the server should be able to stream blocks from some backing server, but copy-on-write them to your own local storage. How is this different from just loading your world in a server and having your friends join? > If you want to be really awesome, set it up like bittorrent, where you can share the load, so the central server isn't hammered. BitTorrent isn't going to work. You could shard it so different parts of the world are handled by different servers. But it gets complicated and Minecraft's server software doesn't support doing this out of the box
- MattCruikshank 5mo ago> How is this different from just loading your world in a server and having your friends join? Because player location, inventory, actions, are all load on the server. That's why servers have player limits. > BitTorrent isn't going to work. You and I are talking about different things. I'm talking about serving up the raw blocks alone. And yes, I know, Minecraft servers don't support static file serving, or streaming from another source, or copy-on-write. I'm saying these are all nearly trivial to implement.
- purrcat259 5mo agoThis is a great video trying to understand the artistic side of 2b2t as a persistent world (rather than the anarchy its more well known for): https://www.youtube.com/watch?v=09m5BAkkOtw https://www.youtube.com/watch?v=09m5BAkkOtw
- naruhodo 5mo ago> A search for vertical 5x5 obsidian/crying obsidian pinwheels was also made, and only 1258 were found, with only 613 within a 25k radius of spawn. There were many more than this in December of 2025, so this is either a sign of other players removing them, or the owner(s) of 2b2t worldediting them all out at some point. I did Nazi that coming.
- lyu07282 5mo agoSpeaking of bedrock, apparently just seeing a few blocks of bedrock (the random pattern of bedrock blocks) is enough to reverse engineer the exact location on the server. I saw a bunch of clips of streamers accidentally leaking a secret base location while touring the server.
- wg0 5mo agoCan someone please explain in layman's terms to me what this means? Background: Only heard the name of Minecraft.
- DaSHacka 5mo agoThis other comment ITT has a good explanation: https://news.ycombinator.com/item?id=48181033 https://news.ycombinator.com/item?id=48181033 The TLDR is a Minecraft server with ""no"" rules, where hacked clients, item dupes, and griefing are allowed. Only thing that's really banned afaik are lag generators and things of that nature that explicitly stress the server and ruin the QoL for everyone.
- Fokamul 5mo ago2b2t is anarchy server where every form of cheating and hacking is "allowed". And thanks to that, people are extremely motivated to find various 0days in anything related to minecraft, to gain an advantage. This server spawned some notorious black hats :)
- Vaslo 5mo agoGlad I am not the only one who found that title and the subsequent readme completely unhelpful, despite standing up and maintaining a VPS server for my son and friends. HN is great but sometimes has the ultimate “tell them about the features instead of the reason why you should care/benefits” posts and many people probably miss out on good links as a result.
- Fokamul 5mo ago$3000 for this? Wouldn't be cheaper to just hack 2b2t DB and download it?
- arboles 5mo ago> Providing a Torrent for this amount of data is not easy whatsoever. We are currently working on creating a Torrent that includes all data, but this may take a few weeks. What do they mean by this? I understand that it would be a download on the order of 26TiB (if we extrapolate from the recent 200k^2 download, which is a ~1TiB torrent[1]). If bandwidth costs are the issue (certainly it's an issue) they could throttle their seeding speed and let the swarm seed it. That's what bittorrent is for.

- Eduard 5mo agoto my understanding, the 2b2t map has a size of 80 terabytes.
- zimpenfish 5mo agohttps://github.com/2b2tplace/1m_release https://github.com/2b2tplace/1m_release has it at 24TB for overworldx2+end+nether
- jdw64 5mo agoDoes anyone happen to have world data from a Minecraft survival server? Could you please share it with me? It would be great if it has some player history included. I'm trying to gather about 10 of them, but it's not easy.
- bombcar 5mo agoWhat kind of things are you looking for? Reach out to Pixlriffs, he has world downloads of his Survival Guide servers and likely access to the HermitCraft ones, too.
- jdw64 5mo agoI've already downloaded Hermitcraft. Thank you, I'll check out Pixlriffs. I'm asking because I have some things I'm curious about regarding Minecraft. Have a great day, and I wish you the best with everything you do.
- arboles 5mo agoCare to share what you are curious about?
- jdw64 5mo agoMy friend is trying to gather and organize data related to this, and I just wanted to help them out.
- adampunk 5mo agoAnonymized chest data, ideally loosely pooled by location. We want to see if patterns show up differently across different kinds of servers. A heavy automation anarchy server is the perfect kind of messy data for this.
- arboles 5mo agoWhat kind of interesting patterns are you expecting? What is the hypothesis?
- palinnilap 5mo agoMinecraft world downloading is an interesting problem, because attempting to solve it by brute force (Loading all chunks in x radius) increases the problem space, because most likely not all of those chunks have been loaded before. So brute forcing it increases the amount of data you must download.
- nektro 5mo agowoah, the web map viewer even has parallax when zoomed in
- z3t4 5mo agoI tried it with a vanilla client, without cheats. The spawn point was brutal, bed rock as long as you could see, large walls and lava. And other players trying to kill you. Had to try several times. Found enough tree to build a pickaxe... dig down, wait for the night. Desperately running trying to avoid zombies. Found a hidden farm, plundered, but two carrots left, enough to not die from starvation. Managed to get outside the spawn zone. Found more tree and food. Walked for several IRL days, old ruins everywhere. Gathered enough resources, built a boat and traveled the ocean. Found a large area surrounded by water and high cliffs, perfect for a base, touched nothing on the surface to not leave any trace, built a hidden farm at a mountain, some secret outlook windows, underwater base. And all sort of traps and labyrinths, prepared for the day the griefers would come.
- itsthecourier 5mo agobasically a post apocalyptic minecraft
- michelb 5mo agoSounds like how my parents went to school.
- plasticeagle 5mo agoI don't know anything about this project, but reading the text in the readme I was very pleasantly surprised to discover not a single hint of the dreaded AI voice in there. Instead, a real human voice shining through. Thank you, whoever you are, for trusting in your humanity and your ability to express yourself without the help of the infernal machine.
- gitpusher 5mo agoI agree it's a breath of fresh air!
- KolmogorovComp 5mo agoI was going to ask how this world is not bot overrun, but I saw that instead players need to pay to get access? (Which is probably the only viable way to keep batting manageable). Does it mean botting there is just pay-to-win?
- gitpusher 5mo agoThe server often has long wait times due to the number of players trying to join, so you can pay for "priority access" and jump right to the front of the queue.
- Fucheese 5mo ago[dead]
- freediddy 5mo agoSo if I download this map, can I run it from my own vanilla Java Minecraft server?
- exploraz 5mo agoIn theory, yes, you could, if you have enough storage space, and if the download provided (not yet) is a vanilla Minecraft world format instead of a custom one that they are using internally
