[[File:{{#setmainimage:Minecraft.png}}|alt=example image|center|frameless]]Minecraft@Home is a volunteer computing project on the BOINC platform that needs your help to research projects related to Minecraft.

Background

Minecraft is a sandbox video game developed by Mojang Studios (now a subsidiary of Microsoft) and first released in 2011. It is the best-selling video game of all time. Every Minecraft world is generated from a 64-bit integer called a seed, which is fed through a pseudo-random number generator and a chain of biome and terrain rules to produce the landscape. Because the same seed always produces the same world, it is theoretically possible to identify the seed behind any Minecraft screenshot or image — but with 2⁶⁴ possible values to check, doing so by hand is impossible for a single person or machine.

Distributed computing makes this feasible: the search space is divided into work units, each tested by a volunteer's computer against landmarks extracted from the target image (mountain shapes, biome boundaries, structure positions), until one seed matches. This brute-force approach, compressed across thousands of volunteers, can turn months of single-machine work into hours.

Why Minecraft@Home?

Minecraft@Home enables the study of the fundamental laws of Minecraft to answer unanswered questions regarding the features and true limits of the game.

Minecraft@Home is notable as one of the only volunteer computing projects to emerge organically from a video-game community rather than from a research institution. Because the questions it pursues are of deep cultural interest to millions of Minecraft players — what is the world behind the game's iconic title screen? where does a legendary screenshot come from? — it has attracted media coverage and public participation well beyond the typical academic BOINC project.

Goal

Discover many of Minecraft's most famous seeds, and investigate the fundamental limits of Minecraft's world generation engine.

Methods

Minecraft worlds are generated from a 64-bit seed. Two terrains that appear identical to a player can originate from billions of distinct seeds. Recovering the exact seed behind a screenshot or a panorama is therefore a brute-force search problem with a 2⁶⁴-sized haystack — well suited for distributed computing.

Why BOINC?

BOINC (Berkeley Open Infrastructure for Network Computing) is a free, open-source middleware platform for volunteer computing developed at UC Berkeley. It allows any project to distribute computational tasks to thousands of volunteers' idle computers around the world, collecting results and awarding credit.

For Minecraft@Home, BOINC provides the infrastructure to divide seed-search tasks into work units, distribute them to volunteers' CPUs and GPUs, validate results, and reassemble them — compressing what would take a single computer months or years into hours. The panorama seed project, for example, represented approximately 93 days of single-machine processing time compressed into just 24 hours through BOINC volunteers, totalling 54.5 exaFLOPs of combined compute.

Many of the Minecraft@Home applications run on GPUs using CUDA or OpenCL, since seed-checking kernels parallelize extremely well on graphics hardware. CPU-based tasks are also distributed for certain project types.

History

Minecraft@Home has found the SEED of Minecraft's title-screen background PANORAMA!

Minecraft@Home grew out of informal Minecraft research communities on Discord in mid-2020. The panorama project began on 14 June 2020, when researcher Tomlacko studied clues in the title screen image — cloud positions, terrain axis, Z coordinate — and shared findings on SalC1's Discord server, where a parallel pack.png project was already underway. A dedicated Minecraft@Home Discord channel and BOINC project were established, and the BOINC server officially launched on 24 June 2020.

The project is community-run with no affiliation to Microsoft or Mojang Studios. Its source code is hosted publicly on GitHub under the minecrafthome organisation.

Results

• Main Menu Panorama — This panorama graced Minecraft's main menu screen for over seven years, from Beta 1.8 (2011) through release 1.12.2. The seed search began 14 June 2020, and in less than 24 hours after BOINC tasks were launched, the seed was found on 18 July 2020 at approximately 5:45 AM UTC. Key contributors included Tomlacko (project founder and coordinate researcher), Earthcomputer, Cortex, Neil (biome/terrain code), DutChen18, MC PseudoGravity, and Philipp_DE.
  • Seed: 2151901553968352745 (or 8091867987493326313; both produce the same world in Java Beta 1.7.3)
  • Coordinates: X=61.48, Y=75, Z=−68.73

Pack.PNG

• Pack.PNG — Pack.PNG is perhaps the most-viewed Minecraft image ever: a 128×128 pixel icon shipped with the game that served as the default server list thumbnail for years. After eight months of work by two teams using BOINC to narrow an initial pool of 281 trillion seeds down to 700,000 candidates, the final seed was found on 5 September 2020 at 4:04 AM UTC — in the last 5% of candidates searched.
  • Seed: 3257840388504953787 (Java Alpha 1.2.2)
  • Coordinates: X=116, Z=−31

The 'Herobrine' World

• The 'Herobrine' World — The Herobrine legend originated in a 2010 4chan post and was spread by a streamer named Copeland who shared screenshots supposedly proving the existence of a mysterious white-eyed figure. The Minecraft@Home project to find the seed of the original screenshot was started by andrew_555 (Kminster), who reportedly spent 50 hours writing the detection code. The search began 5 September 2020 and the seed was found on 16 January 2021 at approximately 12:21 AM UTC.
  • Seed: 478868574082066804 (Java Alpha 1.0.16_02)
  • Coordinates: X=5.06, Y=71, Z=−298.54
  • Other major contributors: Neil, BoySanic, polymetric, DutChen18, MC (PseudoGravity)

Skull-on-Fire Painting

• Skull-on-Fire — The terrain in the background of Minecraft's in-game skull painting. The world seed for this mountain has been found.

1.13–1.16 Menu Backgrounds

• 1.13–1.16 Backgrounds — Following up on the original panorama project, all four remaining menu backgrounds from releases 1.13 through 1.16 were discovered.

Tallest Cactus

• Tallest Cactus — An ongoing investigation into the tallest cactus that can naturally generate in Minecraft. The project has found specimens exceeding 22 blocks in height. The search uses CUDA kernels to sweep the full seed space.

'Smash' Backgrounds

• Smash' Backgrounds — Steve was added to Super Smash Bros. Ultimate; Minecraft@Home is working to uncover the origins of the six different background images used in the game.

Minecraft Trailer

• Minecraft Trailer — One of the most iconic Minecraft videos ever. Minecraft@Home is working to recreate it scene-by-scene by recovering the seeds of each location.

Current Work

As of 21 May 2026, the active application on the server is 1.21 Find large veins of diamond ore, with 778,152 tasks unsent and 5,497 in progress, served to 216 unique users in the preceding 24 hours. The project is currently accumulating a recent compute rate of approximately 9,857 TeraFLOPS.

Media Coverage

Minecraft@Home's discoveries have been covered by major gaming outlets. The panorama seed find was reported by PC Gamer, Eurogamer, and PCGamesN in July 2020. The Herobrine seed discovery was covered by PC Gamer, NME, and Eurogamer in January 2021. YouTuber SalC1 documented the panorama project, and AntVenom covered the Herobrine seed reveal.
