The fallout from Sumokoin’s premine SNAFU and their rash decision to hard fork back to ASIC friendly Cryptonight algorithm resulted in a community backed effort to maintain the original intent of the project of improved privacy and to stay true to GPU miners with CN-GPU.

At block height 137500 what is currently SUMO/RYO have transitioned into RYO and SUMO. Now they are running on a separate chains.

Digital Cash For Highly-Confidential Transactions

Private

Ryo is created with a high level of privacy in mind, setting Ring Confidential Transactions (RingCT) with minimum ringsize (mixin) of 25 to conceal sources/amounts transferred and make it high resistance to blockchain analysis.

ASIC-proof

The Ryo implements Cryptonight-GPU ASIC Resistant algorythm. Ryo, 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. Additionally, Ryo has pioneered technologies such as Cryptonight-GPU, which have been used by numerous other Monero forks.

Untraceable

Ryo is untraceable; sending and receiving addresses are encrypted, transacted amounts are obfuscated by default. Transactions on the Ryo blockchain cannot be linked to a particular user or real-world identity.

Decentralized

Ryo follows Satoshi Nakamoto’s vision of decentralized, trustless cryptocurrency, i.e. a secure digital cash operated by a network of users. Transactions are confirmed by distributed consensus, and then recorded on the blockchain immutably. Third-parties do not need to be trusted to keep your Ryo safe.

Fungible

Ryo is truly fungible, thanks to built-in privacy features. Just like cash, all Ryo are equal, changeable. It is extremely unlikely that coin will ever be blacklisted by any party due to its association in previous transactions

Anonymous

Ryo allows you to use a new ghost address for every transaction you receive. Never receive coins with the same address twice, reducing the chance of linking your transactions to your spending habbits.

COIN SUPPLY & EMISSION

Total supply: 88,188,888 coins in 20 years(including 8M dev. fund emitted together with the block reward over 6 years.), then 263,000 coins will be emitted yearly to account for inflation.

coins in 20 years(including emitted together with the block reward over 6 years.), then coins will be emitted yearly to account for inflation. More than 80 million coins are available for community mining.

for community mining. 8,790,000 Ryo coins were burned to get rid of the original Sumokoin premine. Additionally, 100,000 coins were premined and instantly unlocked to Sumokoin devs in 2017.

The pre-mined coins have been frozen/burned in commit c3a3cb6/ blockchain_db/blockchain_db.cpp#L250-L258 as announced on reddit.

Coin symbol: RYO

Coin Units:

1 nanoRyo = 0.000000001 RYO (10–9-the smallest coin unit)

(10–9-the smallest coin unit) 1 microRyo = 0.000001 RYO (10–6)

(10–6) 1 milliRyo = 0.001 RYO (10–3)

(10–3) Hash algorithm: CryptoNight GPU (Proof-Of-Work)

CryptoNight GPU (Proof-Of-Work) Emission scheme: Ryo’s block reward changes every 6-months according to the following “ Plateau” distribution*. Our emission scheme is inspired by real-world mining production comparable to crude oil, coal and gas which is often slow at first, accelerated in the next few years before declining and becoming depleted. However, the emission path of Ryo is generally not that far apart from Bitcoin.

Now that we know the details about RyoCurrency, let’s get to mining some RYO!
