Not to be confused with the older Eldorado made in 2012 by a random Facepuncher

Eldorado was a massive build project created be Leuphou, where he covered an entire continent in various ore blocks, the majority being gold blocks. It was started on July 29th, 2019, and was griefed sometime in mid-January 2020 by TensiveWolf8599 and Ronaldkekdonald.

History

Founding

Leuphou was bored of building and repairing highways, so he decided to start covering an entire island in gold blocks. Eventually he also got access to dupes and was able to make massive amounts of materials for the base. In the build, the ground blocks are all gold, trees and cacti are made out of iron and emeralds, lava is made of redstone, rivers are made of diamond, and some of the surrounding ocean is covered in lapis. Other builds include a giant gold bird flying above the island, and a gold cavern with a gold pyramid filled with chests of gold under the island

Solution

On September 20th, 2026, one day after Leisc's Eldorado documentary was published, the puzzle's decoding method was reconstructed by Zlizz3R using GLM 5.3. The solution was documented in Zlizz3R's YouTube comment.

The key is the φ symbol in the second hint. It refers to the golden ratio, φ = 1.6180339887..., and the listed numbers are positions in its decimal expansion.

Each number identifies a digit after the decimal point of φ, counted starting from 1. A range such as 5987-5988 means that all digits in that inclusive range are read. The resulting digit groups are then converted using A1Z26, where 1 = A, 2 = B, and so on. Dots separate individual letter values, while vertical bars separate words.

For example, 6686 points to the 6,686th digit after the decimal point of φ. That digit is 9, which corresponds to I. The following group decodes to 20.8.9.14.11, corresponding to THINK. The beginning of the first hint therefore reads: “I THINK I AM DONE WITH THIS PROJECT...”

The first hint decodes to Leuphou's farewell message:

“I THINK I AM DONE WITH THIS PROJECT. THERE IS HONESTLY A LOT MORE THAT COULD BE DONE TO BRING MORE LIFE TO THIS PLACE, BUT THIS DOES NOT MOTIVATE ME ANYMORE. HAVE FUN WITH THE WORLD DOWNLOAD.”

The second hint directly encodes the approximate coordinates. Digits 52,017,087 through 52,017,093 of φ give 1998000, while digits 22,988 through 22,991 give 2000. The minus sign in the hint supplies the negative Z coordinate, resulting in `X: 1998000, Z: -2000`.

Completion, Leak, and Grief

After the island was completed, Leuphou was bored of 2b and decided to leak the coordinates himself via a puzzle involving the golden ratio on November 26th 2019 (puzzle can be found here). After a few months, nobody had destroyed the base still, so Leuphou directly leaked the coordinates himself on the subreddit on January 14th 2020. The base was griefed within a few days by TensiveWolf8599 and Ronaldkekdonald.
