Ah, The 4chan of Minecraft servers, a silly place.
Tiberium•1h ago
2B2T 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 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.

2b2t is so interesting. It is a toxic place, yet you can find really nice things, builds, messages, ... It's fascinating.

The highways especially. You'd think they'd be completely dysfunctional in a place like this.
somewhatgoated•15m ago
They 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.

With 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!

pizzathyme•49m ago
Maybe 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?

You 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.

Besides the spawn area, most blocks have never been touched. It's a lot of blocks.
lanyard-textile•36m ago
The world is mind bogglingly big; as are most minecraft worlds, but this one especially.

People sprawl far to prevent PvP encounters.

aeyes•31m ago
It 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.

And 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
nom•42m ago
This was kept completely secret, so three days ago a separate group released their 200k² world download.

Ups.

For 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•35m ago
You 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•32m ago
I hand waved the details for simplicity, you're correct.

Egregious bugs like item dupes are also patched; but while they last, they're allowed.

> 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•23m ago
Thanks for the info. I was just about to post as a old fuddy-duddy WTF is this. lol

It is also the oldest anarchy server in Minecraft

I'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.

> 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

This 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
naruhodo•28m 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.
