Ryo Currency
Released We have released v0.1.2 of our GUI wallet. View Ryo v0.1.2 releases on GitHub.

Digital Cash For Highly-Confidential Transactions


Ryo is created with a 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.


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.


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.


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.


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.

Whitepaper & Academic Study

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-Heavy, which have been used by numerous other Monero forks.

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 mixins from the start and implementing features such as bulletproofs at a much earlier block height than our predecessor.

Credit is also due to Nicolas van Saberhagen and the CryptoNote team for their original work on the cryptonote whitepaper, as well as the Bytecoin project for creating the first CryptoNote-based coin.

Ryo is primarily a technology focused project, thus we do not spend large amounts of funds for marketing purposes. The founders believe that users looking for a higher level of privacy will seek out and find us. We encourage the community to speak about Ryo in their community.
