RyoCurrency - Privacy for everyone

[Ryo Currency]

Welcome to RyoCurrency​

The fallout from Sumokoin's premine SNAFU. 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 was conceived with the highest levels of privacy in mind. From day one, Ring Confidential Transactions (RingCT) with minimum ringsize of 25 were implemented to conceal every transaction. Ryo Blockchain analysis is impractical. Have piece of mind knowing that what you choose to do with your money is your business, not anyone else's.

ASIC-proof and developing
The Ryo implements the Cryptonight-GPU ASIC/FPGA/BOTNET Resistant algorithm. 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: Uniform payment IDs / CN-Heavy / CN-GPU / Wallet GUI SOLO mining.

Untraceable
As privacy is the core foundation of Ryo, sending and receiving addresses are encrypted and transaction amounts are obfuscated by default. Disposable ghost addresses conceal your real Ryo address from senders, allowing for truly anonymous and untraceable transactions. Our uniform payment ID system makes transactions that use payment ID-s untraceable and hides the very fact that you use ID-s.

Decentralized
Ryo follows Satoshi Nakamoto's vision of decentralized, trustless cryptocurrency, i.e. 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 because of its built-in privacy features. Just like cash, nobody knows who had possession of any particular coin before them. Even better than cash, nobody knows the identity of who they're sending their coins to. It is extremely unlikely that Ryo will ever be blacklisted by any third party due to any association in prior transactions.

Anonymous
Ryo allows you to use a new ghost address for every transaction you receive. Never receive coins with the same address twice, even further reducing the astronomically tiny chance of you and your transactions to be traced.



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.
• More than 80 million coins are available for community mining.
• 8,790,000 Ryo coins were burned to get rid of the original Sumokoin premine.

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)
• 1 microRyo = 0.000001 RYO (10-6)
• 1 milliRyo = 0.001 RYO (10-3)

Hash algorithm: 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.

* These numbers were calculated by the Python script in this repo. Raw spreadsheet data (Excel, Gnumeric) of both current and proposed models are also available in this repo: Github.



WHY YOU SHOULD INVEST IN RYO
https://ryo-currency.com/#roadmap
We have Roadmap that runs since 2017 and partially has already been completed successfully. So we have a clear plan of what to do, and what features to implement.

Responsible DEV team: both Fireice_uk, psychocrypt - are well-known figures in crypto-world: creators of XMR-stak, former contributors to Monero coin project, that proved themselves by as top-grade specialists, that will result in the most technological ASIC-proof e-currency in near future.
We have an active community: people are welcomed to ask their questions and the members of the DEV team find time to support the community across their tough schedule via various social media channels.



THE TEAM and priorities
Ryo wants to be a cryptocurrency that can be used easily by average users, not only developers, so we focus on:

• Developing GUI wallets for both desktop (Win/Mac/Linux) and mobile along with online wallet for beginners.
• Working with payment gateways to make RYO a viable cryptocurrency accepted widely among merchants.
• Keeping improvement in coin security, untraceability, privacy and speed.

Core developers: @Fireice_uk, @psychocrypt, @mosu_forge
Contributing Team: @RyoRU, @Nostradamus411

Credit is due to the Monero Project. Without it, Ryo would not be possible. Monero is a great project, but the Ryo Team believes we can create a more secure cryptocurrency by enabling higher ringsize from the start, implementing a new private transaction system that retrofits to support the old payment ID system.


WALLETS
Local GUI wallet:https://ryo-currency.com/wallet
Previous Ryo desktop GUI Wallet and Ryo LITE Wallet have been merged into one GUI wallet. The development of a brand new wallet, built from scratch using modern Vue.js and Electron frameworks, resulted in the release of Ryo Wallet Atom.
Available platforms: Desktop / Laptop
press release about Ryo Wallet Atom with added SOLO-Mining function.

This algorithm was designed from scratch and suits both AMD and Nvidia GPUs. So it will definitely work ok on green cards - give it a try

Anonymity-oriented altcoin Ryocurrency RYO is still a strong privacy coin with useable features and advance technology. It is arguably the most advanced cryptocurrency in the space, technologically speaking. Every fork brings technological advancements to Ryo.
The sky is the limit, isn't it?

 

[Lawrence]

Have seen solo-mining feature, but don't really know how to start it, is there any guide available on it?

Solo-mining feature is built-in the wallet ATOM, so you can directly mine it from wallet rigs. You can see the whole process of how to solo-mine Ryo here:

[UPDATE][M] Ryo Currency 0.5.0.0 "Fermi Paradox"
Quote
[M] - Mandatory.The update contains security fixes or contains fork update (wallet will stop working after some height reach).

Meet Ryo Currency0.5.0.0 update - Fermi Paradox. In this update we will discuss 3 updates and do one announcement in the source code, 2 of them will be the first among any Cryptonote projects:

• Wallet Scan speedup thanks to ECC and multi-threading library.
  Increased wallet scan speed when processing blockchain. New Elliptic Curve Cryptography library combined with implemented multi-threading that ustilises user's CPU results in reduced block verification up to 5x times compared with previous modes.
• Plateau emission curve.
  Ryo's block reward changes every 6-months following a "Plateau Curve" distribution model. The modification of emission curve was initiated and debated with Ryo community. The following fork will finalise and implement that change.
  Notice: the difference between previous and this model will take effect at block height 394470.
  Read more about Ryo plateau emission curve
• Various code edits, refactoring and minor fixes.
  There are multiple code fixes and edits that could be considered minor when looked in particular, but when looked in general - result in more than 35.000 lines of code being changed making core code more clean, optimised and bugfixed.

Research and studies of Ryo Dev team showed that current ring signature technology as it is - is obsolete and has too many flaws to be considered as a means for reaching the goal of the second level of of privacy. Therefore we will be replacing ring signatures with second generation ZK-proofs technology in observable future and temporarily downgrade privacy level to 1.

In general, you can consider privacy levels like that:

• level 0 - everyone can look into your wallet and know your transactions (BTC level)
• level 1 - nobody can see inside of your wallet, but each note has a serial number (yes, this is real life money level and in CN coins is implemented using stealth addresses)
• level 2 - notes you have don't have a serial number to a guy that gave you one, and no-one can't know if you spent it later (In CN coins it is implemented using ring signatures - which are the failing ones)

What we are saying is over the past year or two, researches stripped ring signatures of their privacy properties so much, that we think it is no longer fair to say that we (or Monero, which is even worse since it has even smaller ring size compared to Ryo) or any other CN project that uses it - meet the level 2 of privacy.

So, summarising in non-tech words what does it mean - when you are doing a transaction and want to imagine how it looks like in system:

• bitcoin - "I spent output 10, worth 1 BTC and output 22, worth 0.5 BTC"
• ring signature (current CN coins) - "I spent output 10, 14, 18 or 20, and output 16, 18, 19, or 22"
• zk-proof - "I spent something."

Fork is scheduledon block 362000: you can check fork countdown on Ryo Currency website

Please update your wallets before this block, or your previous wallet will stop synchronising after the block 362000:

• Ryo Wallet Atom: download latest Atom installer when annouced update to version 1.5.0, start it and perform reinstall.
• Ryo cli binaries: download or compile from source updated binaries from Github version 0.5.0.0 and unzip it, and place your wallet key files in new folder.
• Pool owners and exchanges are notified about updating their nodes to the latest version before the fork.

Questions you might have regarding the fork:
-What will happen with mining algorithm - will it change or what does "fork" mean - coin is split on 2?
No, "fork" basically means major code update that is being activated on a specified block height. There will be no mining algorithm change or chainsplit.

- Ryo roadmap indicates that you had in plans reaching 100x ring sizes. In light of future introduction of ZK-proofs does it mean that this is not aplicable?
Yes, we eventually will be replacing ring signature technology on ZK-proofs, which is more fundamental change than trying to "beat dead horse" with ring signatures.

-What about atomic swaps? Ryo roadmap indicates it being planned, is it still possible with introducing ZK-proofs?
Yes it is! And we aim to implement this feature after all necessary updates in core code. It is important to have everything implemented and tested before adding that feature.

-What is a ZK-proof?
ZK stands for zero-knowledge. In cryptography, a zero-knowledge proof is a method by which one party (the prover) can prove to another party (the verifier) that they know a value x, without conveying any information apart from the fact that they know the value xYou can read more about zero-knowledge proof (with real life examples) here.

-Will blockchain grow faster (what about tx size) when moving to ZK-proofs?
Overall, transactions and blocks using ZK-proofs will be even smaller in size than pre-fork ring signatures with bulletproofs! Plus it enables transactions to be aggregated together - this is obviously a major scalability gain for Ryo Currency.

-I heard or as far I understand that ZK-proofs are somewhat less private? Does it mean that you are not privacy-oriented project anymore?
No, in short - we decided to do this change to second gen. ZK-proofs, because ring signatures as is are too weak on providing enough for us default level of privacy and overall are considered now as an obsolete technology. So we don't want to say that we have a privacy level of 2, when research shows that it is not.

-Ok, after 0.5.0.0 fork - will we be using uniform payment ID-s to do transactions on exchanges?
Yes. There are no changes regarding usage of payment ID-s and integrated addresses. We will be still using ring signatures, but also are announcing our goal on moving to ZK-proofs.

-What else is there in plans/ideas you have in development of Ryo?
Besides all plans and development ongoing with Ryo (wallets, infrastructure, core code and researches) we also developed and improve Mining platform RagerX. It is a all-in-one mining platform that unites a miner, pplns pool, OS, GUI flasher utillity, pool frontend and has advanced social features as well as 2 level affiliate program. In observable future we will add Cryptonight-GPU mining possibillity.We are implementing RagerX so people can mine CPU coins and Ryo simultaneously. Which means more eyes on Ryo, especially from fresh members.

-Are the ring signature issues that have been discovered are applicable to other ring signature based coins like Monero?
Yes.

Happy to see Ryocurrency fork, I invested in it and I‘m very impressed by the strong community considering this project is so young but still very good when it comes to quality and decentralization.
