L4.R0.hash-prefix-1
Hash prefix one byte · ○ open
Challenge
- ladder rank
- #30 (level L4)
- family / transform
- HashPrefix / Identity
- cases
- 1 case(s), 1 output byte(s)
- limits
- program ≤ 1024 bytes, ≤ 100000 steps/case
- purpose
- Exact one-byte SHA-256-derived target; use carefully because it becomes hash-like.
Notes
Output a 1-byte SHA-256-derived value; no known approach.
