10.06.2019

Dear C2CX users:

Skycoin will be removed from the C2CX trading platform on June 7th, 2019 at 15:00pm (UTC+8, Beijing time). In order to give everyone enough time to process their balance, it was extended by one day. In addition, the minimum number of coins to Skycoin transactions has been removed.

All Skycoin trading pairs (LONG_SKY, BTC_SKY) will be closed on the platform.

At the time of this notice, we will immediately close the Skycoin channel.
 
To maintain the benefits of exchange users, we recommend:

1. You can withdraw Skycoin to the exchange or Skycoin wallet. We will be at 15:00 on June 11, 2019 (UTC+8) , Beijing time) Close the Skycoin (Skycoin) coin function, then C2CX start users to transfer Skycoin (Skycoin), if it is not processed within a limited time due to special reasons or technical reasons, please be on June 12 Contact customer service before 18:00 (UTC+8, Beijing time) on the afternoon, invalid. The time limit for the coin withdrawal is based on the current uncontrollability of the Skycoin Skycoin team (see below for reasons of removal).

2. For the sake of safety, we will close the Skycoin automatic coin transfer function from June 5, 2019, and manually check the coin. The coin of the Skycoin will be completed within 48 hours.

3. If you have extracted your wallet address, please extract a small amount of Skycoin test target address before you fill in the target address. If the transaction cannot be confirmed, the address may have been frozen by the Skycoin team. If the address is normal, then carry out the lottery transfer in batches. If you find that your wallet address is frozen, please contact Skycoin Skycoin official channel for rights. If you don't have Skycoin to test in your hand, it is recommended to use a different exchange address as the destination address.

4. At present, in addition to the C2CX start exchange, it can support the Skycoin (Skycoin) trading platform. We recommend the better-traffic currency network and Lbank, users can choose and identify the target platform or wallet to be transferred.
 
A brief description of the reason for the removal:
 
There are several reasons for the exchange of digital coins or tokens on the exchange, such as the lack of liquidity, project team problems and other reasons. This situation is not common in C2CX because C2CX has always followed a strict selection of the currency. The reason for the removal of the Skycoin is an exception, because the cause has almost never been heard in the cryptocurrency industry.
 

On May 31, 2019, the C2CX operations team confirmed that the cold wallet address of some C2CX trading platforms was frozen by the Skycoin Skycoin development team (2i5jm1WU3KnnKbsSoHRtUpkATB9mbw9tyGt). Although we know that the phenomenon that similar wallet addresses were frozen in June 2018 before it happened to other Skycoin holders, this is the first time that the freeze occurred on the exchange's wallet. As an emergency measure, we will remove all trading pairs of Skycoin from 15:00 on June 6 (UTC+8, Beijing time). At the time of this announcement, the Skycoin recharge channel has been closed. The frozen transactions are as follows:

On June 9th, the unconfirmed number of Skycoins was hidden. The following are screenshots of the websites on May 31 and June 4.





Original link: https://explorer.skycoin.net/app/unconfirmedtransactions Similar freeze wallet address events are rare in the cryptocurrency industry because most cryptocurrencies are based on decentralized blockchain networks. In most cryptocurrencies, this is almost impossible. In some special cases, some addresses have been frozen, or some addresses have been blacklisted, but the wallet of the frozen exchange has never been heard. Because this behavior means freezing the funds of the project client's own customers.
 

 
而天空币的区块链却恰恰相反,尽管很多年团队一直在宣传自己特有的共识机制-Obelisk,但是这个共识机制一直只是一个名字。天空币一直在使用由开发团队控制的签名服务器来确认交易这意味着开发团队可以在任何时候冻结任何地址的余额。也就是尽管持有者仍然拥有地址的私钥,但是被冻结地址的交易请求不会被确认。天空币的查询器虽然没有被冻结地址的记录,但目前的版本确实可以查到未确认的交易,目前有多笔。尽管很多天空币的持有者仍然相信项目的未来,我们仍然提醒用户持有一个完全中心化的加密货币在资金安全上的风险性。


 
天空币和C2CX合作的始末
 
天空币项目是一个有野心的项目,其创始人Brandon Smietana是一个有才华的理想主义者,提出以建立新的“互联网”为项目愿景,我们也是一开始被这个愿景所吸引。虽然这个目标看来是真诚的,但不可否认,为达到宣传目的,不少项目的公关文章是有误导性,甚至是完全错误的。例如在安全方面,天空币团队宣称,其网络可以避免51% 攻击和双花;交易确认在秒级别内完成,这些功能在表面看上去是成立的,但实际天空币网络使用的是单体数据库,所谓的矿机节点只不过是主服务器的一个流量节点,并不具有签名和记账功能。以上所谓的“优势”在任何一个SQL数据库都可以实现,通俗来讲天空币用完全中心化的签名服务器掌控所有的资金的出入,51%的防攻击也只是一句空话。再比如:天空币团队一直在宣传混币机制(Coin Join)来增强隐私性,实际情况是Coin Join仅仅是一个概念,从未在代码层面实现过。若混币机制存在,开发团队冻结地址会困难的多。
 
Skycoin claims to be a project that has existed since 2013. In the past 7 years, many teams and individuals have supported this project. In addition to C2CX, and John Mcaffa, the Chinese market team Evolab in early 2018, these partners have fallen into the same strange circle, from cooperation to falling into the project. Party accusations and attacks.
 
The Skycoin project is a project supported by C2CX since 2016. It started with assisting the project team to find resources and pay for development costs. In the latter stage, it mainly supported and stabilized the market value and price of Skycoin. At the beginning of 2017, the price of Skycoin rose from 1 US dollar to 40 US dollars at the end of the year. Most cryptocurrencies were in the doldrums in early 2018, but Skycoin rose against the trend in the spring of 2018 until May 2018. But after that, the price has been falling again and again, from $36 has been falling to $1 in January 2019. Especially between June 25 and July 25, 2018, the C2CX team spent a lot of manpower and material resources to support the skycoin price at $6. Cooperation with Skycoin until November 2018. After that, the Skycoin CEO accused C2CX of arrears, but to this day, he has never provided any substantive details (including the reasons for the arrears and the specific amount of the arrears) and has no interest in resolving the dispute.
 
It is worth noting that during the price plunging period, the Skycoin team found itself that its CEO sold a large amount of Skycoin through the OTC market below the market price. In 2018, the circulation of Skycoin increased by 63%, from approximately 6.7 million to 11 million. From January to June 2019, the circulation increased again by 36% to 15 million. Such continued inflation has caused the market performance of Skycoin to be sluggish.
 
While we continue to wish the project a smooth development, we believe that if there is no real transparency, a truly decentralized approach to managing the blockchain network and not stopping continued inflation, the ambitious goals of Skyco will be difficult to achieve.
