Sumokoin has recently forked into two projects after a hidden premine caused a contentious split between developers.

The original Sumokoin developers have completely shocked their previously loyal followers and the entire GPU mining community by forking back to the ASIC-infested Cryptoknight standard mining algorithm, many left scratching their heads after a move that completely goes against everything they had previously said about decentralization. Effectively killing off the more decentralized GPU mining incentives in an instant and instead at the mercy of Bitmain backdoor hashing. It almost seemed like a bad joke but not, reminding me of a certain Jihan tweet about ‘forking yo momma’. Some are suggesting the erratic backflip comes down to a last-minute cash-grab by the original Sumokoin devs or simply incompetence and survival. It seems RYO is now the real Sumokoin not only in spirit but more importantly in continuing forward with the ASIC-resistant (Cryptonight-Heavy) Sumokoin blockchain and greater transparency.

Sumokoin, the project that not so long ago had everything going for it has suffered dishonor, but all is not lost as that project has now given birth to something with an even greater potential. The reputed RYO devs are led by the respected xmr-stak mining software developer fireice_uk, who uncovered the premine inconsistency and pleaded that the Sumokoin devs be transparent with the public as they rectify the situation. Fireiceuk is the creator of the ‘Cryptonight-Heavy’ algorithm, one of the most ASIC-resistant POW algorithms in existence that continues to get so much love from the global GPU mining community. The Sumokoin devs had originally commissioned fireice_uk to develop it for the purpose of Sumokoin becoming the most ASIC-resistant privacy coin all in the name of decentralization. Sumokoin’s recent shocking excuse to go back to ASIC-infested waters in the name of decentralization, was the point of Sumokoin’s complete loss of credibility. The news of this hardfork has certainly taken its toll on the price of both coins but the good news is that RYO is making great progress in lightning time and there’s lots of exciting developments in the works for the project in the near future.

This debacle all started after fireice_uk discovered a premine discrepancy, which he brought to the attention of the Sumokoin devs and when the team were not being able to come to an agreement, with fireice_uk pleading for transparency, a publicly published ongoing development budget and the destruction of the ‘hidden premine’ – he decided to take this information public ousting the dishonest Sumokoin devs and take over the leadership of the project with the support of the majority of the community. The original Sumokoin developers had an ‘accidental’ undisclosed 400,000 coins that were to be unlocked in June. As the fallout between old and new devs unfolded, fireice_uk presented screenshots from telegram discussions showing the dishonesty of Sumokoin devs and proving his claim’s legitimacy.

RYO is available to buy and sell on TradeOrgre & Cryptopia.

RYO source code decision: OpenSource or SourceAvailable?

How to claim both Sumokoin & RYO coins if you held Sumokoin before the Hardfork

 


 

 

 

Over the course of the project members of the team and community have come to possess knowledge that misrepresentations were being made about the Sumokoin (a.k.a. RYOCurrency, a.k.a. RYO) project. A small group from the community wants to set the record straight, and announce a transition of leadership under the best possible conditions one could hope for.

To be direct and upfront on the misrepresentations :
2 of the “Founders” are phantoms (Bill Aue & Sumoshi Tanaka),
1 of the “Founders” is an innocent bystander whose identity and academic credentials were attached to the project without his knowledge (Haruto Tanno),
Prior to the addition of Fireice_uk, the developer skillsets were oversold and outsourcing of work was required by an unknown team.

In response to the discovery of these falsehoods :

Effective immediately; overtaking control of the Sumoprojects Github and all further Development of Ryo/Sumokoin will be transitioned to Fireice_uk and Psychocrypt, Sumogr, Patrik, and Vu Quang have gracefully agreed to step aside for future’s sake of RYO project, The new leadership is committed, and will propose very soon, measures to make the premine and the development more transparent and democratic for everyone.

In light of these facts, the current Sumokoin leadership has chosen to honorably stand down from the project they began. Moving forward , the new RYO team has sworn to uphold the best possible transparency whilst, upholding the move for Privacy without compromise. The new Ryo team is dedicated to make the development process more transparent and to uphold Ryo’s aim of user privacy without compromise.

The following two PRESS RELEASES are UPDATES from the RYO team as at May 29th, 2018

PRESS RELEASE

>Ryo, What Happened?
We understand that the last few days have been very confusing for everyone. We would like to explain in an unbiased manner, the events leading up to now. To get the clearest picture, we will start from April of this year.

April 2018
Fireice_uk was hired to develop cryptonight-heavy for the Sumokoin team. The coin successfully upgraded with this new proof of work algorithm. Later in April, Fireice_uk was officially
brought on board team Sumokoin.

May 2018
Many things happened concurrently in this month. First, the core team decided it was time to rebrand Sumokoin in to Ryo. Fireice_uk was a part in this rebrand efort, and some say it was an
early attempt to subvert the team, which is a rumor spread by the original PR team.
At the same time of the rebrand, the first unlock of 600,000 coins from the premine was closing in. Fireice_uk, now being a core member of Sumokoin had a disagreement on how to
allocate the funds. At this point there were two internal development teams. The first one led by Fireice_uk, and the other one, led by Vu Quang. Each team was promised 200k coins, for use at
their sole discretion.

Fireice_uk proposed 50% of the premine be set aside in a transparent development fund, and the remaining split up into transparent wallets for; PR, design work, and misc. expenses. This
idea was proposed to Vu and the other members of the Sumokoin core team but, unfortunately there was no agreement to this. A rumor was spread that Fireice_uk wanted more than the 30% he
was offered. This was proven to be false, as he offered the team that he would be willing to take only 10% if his budget proposal was approved.

With no agreement in place, Fireice_uk walked from the project since he felt that there should be a clear budget on a long term project. 

May 2018 (Cont.)
In the latter part of May, Fireice_uk approached some prominent community members asking for their advice. He explained that he found a discrepancy in the premine amounts that
were to be unlocked. 1,000,000 coins would be unlocked instead of 600,000. He asked these members he reached out to and ofered to either 1) Resign or 2) Organize a community efort to
create a new team. A portion of the community backed him and a new team was created.

On Sunday, May 27th, the new team announced their intentions and suspicions of the current dev team. Issue included the dishonesty of the premine amount, accusations of “ghost
developers,” and the need for a clear cut budget. The community reacted negatively to this, and the new team was ostracized.

On Monday, May 28th, a press release was put out by the new team showing details of the extra 400,000 coins to be unlocked. It included instructions for anyone to verify on the blockchain,
this claim. When members of the original core team verified these claims, Sumogr and Patrik stepped down from their role having lost trust in the original developer, Vu Quang. Later in the day,
Vu Quang announced that there was indeed an extra 400,000 coins unlocking and that he had mistakenly done this.

Tuesday, May 29th (today as of writing this PR) many in the community are not sure what is happening with the team. Both Vu Quang and the team led by Fireice_uk are claiming rights to the
coin Sumo/Ryo. If both teams do continue in their development, it will be up to the community to decide which team they will recognize as the official developers. The community should decide on
this by choosing which team’s daemon and wallet to run once each team releases a new version, as is the case for every coin’s change of consensus rules.

PRESS RELEASE


Ryo, Where We Go From Here?
 
Note: this document is published by the team organizing with Fireice_uk. The original developer, Vu Quang, also claims the rights to the project. Please read our previous PR entitled “Ryo, What
Happened?” for more information on the events leading up to this.
We understand many members of the community are in search of answers on what will happen to Ryo if they accept and back the new core team. In this document, we will announce our team
members, roadmap, and plans for premined funds. Please note, that supporters and investors of Sumo/Ryo do not need to do anything with their coins at this point, and their funds are safe.

Team Members
Initially, the core team will consist of the following members: Fireice_uk and psychocrypt (the developers behind xmr_stak) will take leadership of all core programming on the daemon and
command line wallet binaries. Mosu_forge will continue on the GUI wallet coding he started early in April. Certain team members will support the community and act as liaisons for the moment. As
more projects are put on the roadmap, members of the community will be pulled into more roles, as well as new programmers will be added to the team.

Lead Programmers (C++ development, daemon):
Fireice_uk
psychocrypt
Support:
Nostradamus411
Soapy Fresh
K3v1n M4h35h Other Programmers:
mosu (GUI Wallet, website)

Roadmap
The new core team is excited to move Ryo along and add new features to the coin. At frst, we will
need to take care of management issues such as domain names, official pools, etc. After the small
housekeeping items are taken care of, you can read below the new roadmap for Ryo. There are no
dates on the below items, but every feature is planned to be released this year.
- New daemon that will rebrand Sumo to Ryo, and invalidate the current premine, until a
solid budget plan can be put in place.
- Introduction of Fireice_uk’s optimized EC improvements.
- Introduction of, multi-signature wallets allowing a more trustful developer fund.
- Integration of, bullet-proofs on the testnet chain. Integration to the mainnet will be delayed
until a qualifed mathematician can verify its validity.
- GUI wallet update, fixing the responsiveness of the current GUI wallet, and introducing a
dark theme as well as, international translations.
- Easy to use and secure web-wallet
- Introduction of “identicons” across the GUI and web wallets, allowing for quick verification
that a Ryo address is entered correctly.
As always, new features will be added as new members of the team are added.

Current Premine Funds
Sumokoin’s original premine amounts were to be unlocked over three years, with 600,000
unlocked in 2018, 900,000 unlocked in 2019, and 6,100,000 unlocked in 2020. Due to an error by
the original coders, 1,000,000 would be unlocked in both 2018 and 2019, with a smaller amount
unlocked in 2020. We feel this large amount being unlocked in one year is detrimental to the
health of the coin.

Future Premine Funds
Since the premine of Sumo/Ryo is fairly significant (10%), we would like to offer a solid plan on
how to use the funds.
- We will invalidate the current premine with a new daemon release.
- Until the dust settles and the new dev teams has gained the support of the community, all
developments will be done without payment to the developers
- Eventually, a new premine will be created that will be locked for 5 years with a portion
being unlocked each month.
It is important to note that, when a new premine is issued this will not affect the total supply of
Sumo/Ryo in general, it will replace the existing premine. Only in a case that, less than 10% is
decided to be the new future premine will there be any effect.



 

For several days now Cryptopia has frozen all Sumokoin (SUMO) deposits and withdrawals. The Ryo Team
is disappointed with Cryptopia’s decision in this matter. Although Ryo is now a distinct project from
Sumokoin, we care for the investors and community that allowed us to reach where we are now with the
Ryo Project.

The Ryo Team takes great pride, and also remains true to our beliefs in being transparent to you, our
investors and community. As such, we are making every efort to compel Cryptopia to lift this trade
blockade. However there is only so much we can do.

 

We, the Ryo team, are under the impression that Cryptopia is interfering with the free marketplace
cryptocurrencies have made possible, and are putting us in a position where they can easily demand
payment of their high listing fees. Therefore, the Ryo Team is not considering now, or in the foreseeable
future, paying for a listing at Cryptopia. We choose this in order to discourage such situations from
occurring ever again.

We urge anyone who had Sumokoin stuck on the exchange at the time of the fork to contact both
Cryptopia as well as the original Sumokoin team. The Ryo team is willing to ofer Cryptopia free technical
assistance in allowing their customers to claim and withdraw their Ryo from the hardfork.
On a final note, no Ryo team member has misleadingly sent any email to Cryptopia masquerading as the
original Sumokoin team, as has been claimed in announcements from Cryptopia themselves. On the
contrary, our communications have been crystal clear; we are a different team, with the backing of the
community.

In the meantime, we are working on getting listed at multiple exchanges and will keep the community
posted the soonest possible on any new listings.

Sincerely,
Team Ryo

P.S. As evidenced by the above, we want to remind you the only safe place for your funds are in your
wallet which you have the private keys for. Only leave coins on exchanges that you are willing to lose. We
understand the timing of Sumo’s price plummeting along with this account freeze made for the perfect
storm where many people lost access to the Ryo they wanted to claim from the fork

 


[DECISION] Our source code will be source-available for 6 months

Thanks to everyone who participated in the community debate!

I would like to summarize the best points and explain our decision:

Points against:

“If you are worried about low effort fork coins, which are barely a step up from scams, I doubt they will care about licensing. So I would assume they will rip off anything that isn’t bolted down regardless.” [1]

That’s a defeatist attitude. Why do anything at all then? In my opinion even if someone gets the code hosted on a bulletproof server, what are they going to say? “Hey, we stole the code, but we totally won’t steal your money?”

“open-source is best because if this team fucks it up, it means someone else can take the work done and lead it in a more positive direction” [2]

One of the best points against. We addressed this by adding a fixed sunset clause — in six months the code is going to be in public domain.

“Trust will decline as a fork cannot use that code. […] Even if the source-available is limited to a defined time till it gets open source it would delay a fork which could be time critical and therefore lower trust.” [3]

I’m probably a dumb sheep since I don’t grasp the logic here. You don’t trust BMW because they won’t let you build the car yourself and sell it on?

Monero guys made a surprisingly strong representation against:

“As already mentioned in other posts, low effort pump and dump shitcoins will rip your improvements anyway regardless of licensing terms, so the only benefit to you is to prevent Monero devs from copying your code (and instead having to reimplement it from scratch) since you are feuding with them. The effect of source-available will be to label you as an opponent of open-source in the eyes of open-source devs.” [4]

Apart from the rehash of the defeatist point, this adds a fairly interesting dimension — “don’t do it or Monero guys will FUD you”. To be frank they called me every available name under the sun by now probably. I don’t think “enemy of open source” is going to make a huge difference, but it gives me a chuckle that the same guys describe open source as malicious. [5]

“As was my AMD OpenCL XMR miner (at the time, the only one comparable to Claymore’s) which you took off my git and combined with another poor dev’s CUDA to make xmr-stak, with a 2% fee your way. It’s not like there’s a legal issue — you do as you please. You need no one to co-sign your shit — if I said I didn’t think you should take the option you wanted… would it really change your mind?” [6]

He probably didn’t realize that one of us is a fanatic open-source zealot =). [7]

Points for:

I will quote only a single post here since it has five good reasons (sorry to everyone else who outlined points for):

Thanks for all the input everyone!
  • Ryo isn’t a billion dollar coin. Keeping it open source will spawn a dozen copy cats all claiming to be better than it.
  • Ryo shouldn’t just survive based on acknowledgement for it’s improvements. People will recognize fireice’s work regardless whether the project is open source or not. Claiming that people will only recognize open source is not correct.
  • Ryo needs to survive now. It’s has less than a million dollar MC. And if it were to open source now, it will be a death sentence. We are in a very niche section of CryptoCurrency. Not lot of people know about the coin. Right now would not be the right time to open source the project.
  • Things are changing, projects now are protecting their work. Fireice’s should do the same. It is his work, and he has the right to bear fruits to his labor.
  • Ryo needs to differentiate itseld with the competition. Open sourcing it now will kill this. You can be sure ryo will die with noone to see it if it open source it’s work. [ 8 ]

Fireice_uk

I have Sumokoin, how can i claim my Ryo?

  • You can claim your Ryo, if you had Sumokoin before they forked at block #137500. Ryo Currency as a chain fork kept all the transactions -and thus coins you had in your wallet- up and until Sumokoin forked at block #137500. To further secure your Ryo, we’re going to tie the coins to a block after the fork.
  • First, install the latest Ryo wallet. Run it and generate a new wallet. Write down the seeds. Copy the MAIN ADDRESS under the RECEIVE tab. Then from the Ryo gui, click SETTINGS » NEW WALLET and restore your Ryo from the same seeds used for your old Sumokoin wallet in the Ryo GUI.
  • Send all your coins to the new Ryo MAIN ADDRESS you copied before. After this, you can safely transact Sumokoin, it’s important to first move your Ryo, before you move your Sumokoin.
  • If you are comfortable using the CLI, you can just SWEEP ALL Ryo to yourself instead of all the above.

If you want to dig deeper, there’s plenty of reading on the public record from Fireice_uk. He/she/they has a back catalogue of open-source coding activity on Github and lengthy discussions/public debates on forums as reddit, the coder of XMR-STAK also seems to chat regularly to their community on telegram. I dug, in more ways than one. I emphatically liked what I saw in terms of work and discussions on RYO, Sumokoin, xmr-stak’s public github & social media history. The way he handled the Sumokoin hidden premine fiasco may be controversial but he’ll happily discuss openly with respectful inquirers on telegram. However, when I dug deepeer into post-fork scrambling Sumokoin devs asking some basic questions about the hardfork respectfully, I was quickly banned from their telegram and many people were also reporting Sumokoin telegram channel censorship bans. Winner by KO is…. RYO.

Monero’s Fluffypony once called Fireiceuk “an enemy of open source”.

In regards to Source Available, is it an enemy of Open Source even if only locked in 6 months? Can Source Available co-exist alongside Open Source to help small teams protect their hardearned uniqueness and survive getting off the ground against their behemoth aggressive rivals?

What do you guys think about the Sumo / Ryo fork, Fireiceuk’s Source Available argument and the recent developments?
