## Who this is

Another handle from ZorenX's write-ups. [Arweave Puzzle 13](https://puzzles.agntn.dev/collections/weave/13) was one of the Ethereum ones in the series, 1 ETH behind an image. You identify what's in eight pictures, the labels go through SHA-256, and pieces of the hash become the key. It went up on May 18, 2020 and moved four days later.

Four days for an image puzzle is fast. Image puzzles usually eat weeks, because the first idea is always steganography and the first idea is usually wrong.

## What the record says and what it doesn't

One fact, the write-up. A LeFevre also turns up as a helper in other people's puzzle write-ups from those years, which is fun, but a similar name in a thank you line is not the same person on the record. It stays one handle and one solve until something links them.

## The record

```ts [src/collections/weave/13.ts]
