The fork has occured on block 362000.

Ryo will fork on block 362000 which is approximately in:

Meet Ryo Currency 0.5.0.0 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 10x times compared with previous modes.

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 morally 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)

- 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)

- 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."

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.

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.

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.
