Bitsikii Extension Interface(BXI)
The Bitsikii Extension Interface (BXI) is a compact 4‑bit binary encoding system developed in 2025 by Filipino cryptography enthusiast **Rodson James Perez** (username RodsonTP) 2. It represents alphabetic characters using a simple mathematical rule:
- **BXI(n) = ⌊n / 2⌋ + 1**, where *n* is the alphabetical index (A = 1, …, Z = 26) 3.
Rather than mapping each letter individually, BXI groups letter pairs (e.g. B and C, J and K) under the same binary value to produce 14 distinct 4‑bit codes 4. The result is a lightweight, human-readable encoding mechanism typically used for educational tools, cipher challenges, or binary logic demonstrations.
BXI first appeared in a June 28, 2025 Medium article by its creator and has gained attention in coding and puzzle communities online 5.
