Ryo is one of very few cryptonote currencies that does actual, rapid development. Its team is led by fireice_uk and psychocrypt, who are the developers of xmr-stak mining software and the cryptonight-heavy algo which has been used by several Cryptonote projects and pioneered first in industry floating point mining algo Cryptonight-GPU. Another lead developer - mosu_forge introduced first GUI Wallet with SOLO mining features among any Cryptonote projects. Ryo dev. team also developed mining platform - RagerX.
Though the project started on June 2018, the Ryo team has several vectors of development, and it has already brought results that we can see:

Source code

Powered by a professional development team, Ryo already has implemented several features into its source code; here are some of them that we would like to mention:

• [Announced] Second generation Zk-proofs.
• [Implemented] ECC library with Multi-threading: heavily reduces wallet scan times.
• [Implemented] New transaction ID system, to plug metadata leaks in Monero tx ID system
• [Implemented] CN-GPU proof-of-work hashing algorithm.
• [Implemented] Default ringsize is increased to 25.
• [Implemented] Shorter 'kurz' addresses for people who don't need a viewkey
• Poisson probability check to prevent Verge-like offline timestamp attacks
• [Implemented] 12 bit seed validation check, also known as CRC-12
• [Implemented] Multi-language, non Latin characters with proper seed validation and display in wallet.
• [Implemented] Wallet restore height into seed extra data
• Various critical bugfixes and code improvements

Ryo Wallet - Built from scratch with a modern codebase & feature rich

The initial version of the Ryo GUI wallet was welcomed by community as a user friendly and intuitive solution for sending and receiving Ryo. However it was built with outdated technology, so the Ryo wallet team decided to continue further wallet development using Electron framework and Vue.js The aim of creating an industry leading multi-language and multi-platform GUI wallet has already resulted in release of the Ryo Wallet Atom, available for Windows, Linux and MacOSX.

• Solo mining feature. Built-in pool software with workers support, statistics and graphs display.
• Mnemonic seed confirmation
• Password strength checker
• Inactivity log-off timeout
• View-only wallet option / keys management
• Multi-sync (Local / Remote / Hybrid)
• Multi-wallet (Switch Ryo wallets with ease)
• User friendly address book
• Legacy GUI wallet one click import
• Various UX/UI improvements over previous versions (wallet naming, identicons etc)

Providing the best privacy, security, and ease of use have been the guiding principles from the start of Ryo. With that, we are proud to release our ultra-fast WEB based wallet: Ryo Wallet Quasar. Ryo Wallet Quasar brings the user friendly interface of our desktop GUI wallet. (Atom) to the web and mobile platforms.

• Android and iOS support
• Mnemonic seed confirmation
• Password strength checker
• Inactivity log-off timeout
• Integrated address generator
• Native app support

Development Fund

In an effort to provide transparency to the community on how the development fund is allocated, we built the following Dev-Fund Explorer page that categorizes data and provides an at-a-glance report on where the funds are being spent.
The funding is grouped into four categories:

• Staff
• Hosting
• Marketing
• Miscellaneous

Funding is grouped into four week periods and details are made public a few weeks after the period closes. While the Ryo team strives to provide the upmost transparency, we believe that real time figures could leak material information and be used for speculation on the open market.

Infrastructure and support

Infrastructure and support matter. The widespread Ryo support team provides online support for community and news. Our support and updates are present at ten social channels in several languages. You can join our community and ask the developers about their perspectives, ask for technical support, and get the latest news.

The Ryo dev team has also set up a powerful load-balanced public node which adds ease of use while synchronizing wallets for new users. By default, the new Ryo Wallet will use our remote node while downloading the blockchain for a proper balance of privacy and ease of use.

Ryo for business

The Ryo Business room is channel where we can build a community of people with a large interest in Ryo-currency. It exists to foster ecosystem development and incentivise holding while enabling business people to work together.

In order to join, you must hold an interest in the project by having at least 50,000 Ryo and provide key images as proof. The reason this is a requirement is to make sure members are serious about the project and have the capital to make their ideas a reality. Alternatively, we may invite members of the community who have already contributed noteworthy components to the Ryo ecosystem. Large pool operators are also welcome to join the group.
Note: that you are not required to send us 50,000 Ryo, just provide proof that you hold that amount in your wallet. Join our Telegram channel and send direct message to our @RyoSharkBot to get invite to the group.

Ryo for web developers and their customers

Our team created WooCommerce plug-in for web developers. This is not just a rebranded version of the Monero wordpress plugin, it has tons of new features and makes accepting Ryo on your webstore accessible to everyone. Explore our Ryo gateway on Github . It is well documented, ready to use solution, that is being used on official Ryo Store as demonstration of its capabilities.

Security research

With privacy and security as the core foundation of Ryo, we invest time and effort into security research as well as investigate and analyze issues with the Cryptonote protocol in order to bring true default anonymity for users.

Ryo currently uses RingCT with a ring size of 25, however it is our decision that RingCT cannot fully protect against transaction tracking. As our promise to create the most private and untraceable cryptocurrency, we are planning on replacing RingCT with second generation ZK-proofs.

1. Hiding your IP while using Ryo or other Cryptonotes
2. Tracing Cryptonote ring signatures using external metadata
3. How buying pot with Monero will get you busted — Knacc attack on Cryptonote coins
4. On-chain tracking of Monero and other Cryptonotes. (aka Graph analysis of transactions)

Core Development Path

This section is deliberately small - anybody can promise the moon and the stars. We - deliver. The planned core update features are unique and have never been done in Cryptonote coin development:

1. x5-x10 speed up in CPU usage during sync and operation which is a major bottleneck and a good target for performance optimisation of wallet and blockchain sync times using ECC library + multi-threading.
2. Increasing default ring sizes. First increase of default ring size 13 -> 25 was introduced in 0.4.0.0 update.
   Ryo currently uses RingCT with a ring size of 25, however it is our decision that RingCT cannot fully protect against transaction tracking. As our promise to create the most private and untraceable cryptocurrency, we are planning on replacing RingCT with second generation ZK-proofs.
3. Cryptonote blockchain compression, down into below 1GB sizes for Monero, 100MB for Ryo. Instead of current the current 60GB for Monero, 15GB+ for Ryo.
4. Combination of faster processing (1) and compressed blockchain extracts (3) and a specialised server to create custom name Electrum-like wallets.

Where can I use Ryo

Cryptocurrency projects should live up to their name, and a well maintained source code is only part of that. Currencies need real life usage. One of our goals is to build a strong ecosystem around Ryo making it easy to interact with.

Contact our community if you want to start accepting Ryo on your site or platform .

Ryo pool list page on miningpoolstats will help you to pick up pool for mining, check stats and network info.

Trading

Currently, Ryo can be traded with these crypto/fiat pairs:

• NONKYC.io exchange
  RYO/XMR / RYO/BTC / RYO/USDT

• SOUTHXCHANGE
• TRADEOGRE

Ryo dev team plans to continue work on getting listed at several other payment processors and exchanges.

Contributing

Although Ryo Currency code in main repository is source available until February 2021, we have contributed back bug fixes and features to Monero project:

• Add Unicode input line
• Fix for a wallet caching bug

On Feb 1 2019, we duplicated the ryo-currency repo as ryo-currency-libre . This new repo will always contain public domain code, and will be updated any time new code becomes public domain.

Also on Feb 1 2019, we updated the license on the main ryo-currency repo to protect the code for another 12 months. Thus code will be source-available until Feb 1 2021.

Loki and Arqma projects decided to use own version of wallet, based on Ryo Wallet Atom ( libre repository) as their official GUI wallets.

Projects that are using Cryptonight-GPU mining algorithm:
