 ## Introduction
 
 Sumokoin (スモコイン in Japanese) is a fork from Monero, one of the most respectable cryptocurrency well-known for **security, privacy, untraceability** and **active development**. Starting as an educational project, we found that it would be great to create a new coin with high level of privacy by (1) moving forward right away to **Ring Confidential Transactions (RingCT)**, (2) setting **minimum transaction _mixin_ to 12** that would greatly reduce chance of being attacked, traced or identified by (blockchain) statistical analysis.
