In a remarkable achievement for the gaming community, a dedicated group of Minecraft enthusiasts has successfully mapped the entirety of 2b2t, a server renowned for its history and complexity. This monumental task culminated in the release of a 15TB download, which, when unpacked, reveals a staggering 80TB archive of data. To accomplish this feat, the team developed a custom compression format, demonstrating both ingenuity and technical prowess.
The Journey of Preservation
The 2b2tplace preservation project embarked on its ambitious journey in 2024, concluding after an intensive 22-month effort in April 2026. This endeavor required the use of 28 bot accounts, which meticulously traversed the expansive 2b2t world to document every block with remarkable accuracy. The scale of this undertaking is truly impressive, as it encompasses over one million blocks across the three primary dimensions of Minecraft: the Overworld, the Nether, and the End.
Managing and sharing 80TB of data presents significant challenges, particularly in today’s landscape of limited and often costly storage solutions. The archival team initially pledged to provide the archive in a compressed format, but the complexities of such a large dataset necessitated a more innovative approach. Thus, they engineered a new file compression format, dubbed .zvcr (Zstd-compressed Version Controlled Regions), tailored specifically for this project. This contrasts with the traditional .mca (Minecraft Anvil) file format, which is typically suitable for smaller servers or single-player experiences.
As the gaming community eagerly anticipates the implications of this monumental archive, the project stands as a testament to the dedication and creativity of its contributors, paving the way for future endeavors in digital preservation.
