SUMOKOIN (SUMO) | Monero Fork| Digital Cash for High-Confidential Transactions

  • Sumokoin is forked from the source code of Monero cryptocurreny, one of the most innovative digital coins which is well-known for security, privacy, untraceability and active development, therefore, naturally inheriting all of those great features, yet without the burden of its past

    Cryptonote Over View:

    The CryptoNote Technology 

    Now that we have covered the limitations of the Bitcoin technology, we will concentrate on presenting the features of CryptoNote.

    Untraceable Transactions

    In this section we propose a scheme of fully anonymous transactions satisfying both untraceability and unlinkability conditions. An important feature of our solution is its autonomy: the sender is not required to cooperate with other users or a trusted third party to make his transactions; hence each participant produces a cover traffic independently.

    Literature review 

    Our scheme relies on the cryptographic primitive called a group signature. First presented by D. Chaum and E. van Heyst [19], it allows a user to sign his message on behalf of the group. After signing the message the user provides (for veri cation purposes) not his own single public

    Sumokoin,as a fork from Monero which itself was initially based on the CryptoNote protocol, inherits all whitepapers and academic studies from CryptoNote and Monero Research Lab:

    Initial Review of the CryptoNote Whitepaper

    MRL-0001: A Note on Chain Reactions in Traceability in CryptoNote 2.0

    MRL-0002: Counterfeiting via Merkle Tree Exploits within Virtual Currencies Employing the CryptoNote Protocol

    MRL-0003: Monero is Not That Mysterious

    MRL-0004: Improving Obfuscation in the CryptoNote Protocol

    MRL-0005: Ring Signature Confidential Transactions


    • 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 (mixin) of 12

    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 Symbol: SUMO

    Hash Algorithm: CryptoNight 

    Network Power: Proof-of-Work (PoW) 

    Block Time: 240 seconds (approx.) 

    Maturity: 60 blocks 

    TX Fee: Dynamic (based on TX size and block reward)

    Total Supply: 88,888,888 coins in first 20 years, then about 263,000 coins (~0.3%) each year for inflation.
    About 10% (~8.8 million) was premined to reserve for future development, i.e. over 80 million coins available for community mining

    Coin unites:

    1 Sumosan  = 0.001 SUMO (10-3)

    1 Sumokun = 0.000001 SUMO (10-6)

    1 Sumoshi  = 0.000000001 SUMO (10-9 - the smallest coin unit)

    Emission scheme:

    Sumokoin's block reward changes every 6-months as the following "Camel" distribution* (inspired by real-world mining production
    like of crude oil, coal etc. that is often slow at first,
    accelerated in the next few years before declined and depleted).
    However, the emission path of Sumokoin is generally not far apart from
    what of Bitcoin (view charts below) indicating long-term existance and

    For curiosity, please consult this script which emulates the algorithm of Sumokoin's block-reward emission ** Calendar months for block reward changes are estimated (based on difficult target * heights) and, therefore, would be a bit different in practice. Block reward for each turn is also not a fixed number yet not expected to change much (if any)

  • SUMOKOIN (SUMO) Release GUI Wallet v0.0.2


    This version is to incorporate subaddresses feature (named "Ghost" addresses) to UI. 10 "ghost" addresses are always available to use while used addresses are grouped with available balances.


    • The new wallet binaries are not fully compatible with old wallet files. After upgraded, you should run "Rescan Blockchain" to refresh wallet and reveal all transaction history. That's highly recommended.

    • Exchanges may not update their wallets to the latest version so that withdrawal to subaddresses would result in errors. Please make consult supports before using subaddresses for coin withdrawal.


    • Full support for sending and receiving to subaddresses.
    • Receive tab shows ghost addresses along with main address, ready to use.
    • Various bug fixes for better wallet stability.
