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 mixins to 48 that would make it high resistance to blockchain analysis attacks.

Sumokoin, therefore, is a new Monero without its legacy, a truely fungible cryptocurrency among just a few ones in the market.

Features

#TRUE FUNGIBILITY
Sumokoin is one of a few rare cryptocurrencies with true fungibility — the feature makes digital currency act like physical cash i.e. no other people can find where the money comes from and how many have been transferred.

#GREAT PRIVACY
Sumokoin is created with high level of privacy in mind, setting Ring Confidential Transactions (RingCT) with minimum ringsize of 48(+1) to conceal sources/amounts transferred and make it high resistance to blockchain-analysis attacks

#STRONG SECURITY
Sumokoin utilizes the power of a distributed peer-to-peer consensus network, every transaction is cryptographically secured. Individual accounts have a 26 word mnemonic seed displayed when created, which can be written down to back up the account and account files are encrypted with a passphrase to ensure they are worthless if stolen.

#Coin Info
PoW Algorithm: CryptoNightR
Max Supply: 88,888,888
