关于币付宝和比特沙停止运营的公告

这是一个令人感慨的结束!

背景:

比特币以单链形态稳定运行了八年,却面临分岔而将进入多链时代。

币付宝和比特沙在比特币单链时代稳定运行了四年,不得不面对多链的复杂问题,但这却与币付宝和比特沙运营原则违背。

INB(INBlockchain) 已经长大,全新的公众参与方式呼之欲出。

所以,与其说是一个结束,不如说是一个新时代的开启。

币付宝和比特沙宣布将于2017年10月1日正式停止运行。

停止运行前,几个相关问题的说明:

  • 币付宝和比特沙不支持任何分叉币,所以,如果你想获得比特币分叉品种,可以把比特币提取到承诺分配分叉币的平台,如云币。

  • 比特沙利息发放截止到 2017 年 8 月 1 日为止。之后不再发放利息。

  • 因分叉问题造成暂停提币的时间表见云币公告。

  • 2017 年 10 月 1 日将停止即时提现业务,9 月中旬我们会开始对未提现的用户进行电话和邮件的提现提醒。

  • 2017 年 10 月 1 日之后,所有未提现的用户再申请提现将需要 1 周时间,且于 2018 年 5 月 1 日停止一切业务受理。

Announcement on Business Closure of Bitfoo and Bitcoinsand

After eight years of steady operation as a single chain, Bitcoin is facing the possibility of hard forks. This, however, disagrees with the operating principles of Bitfoo and Bitcoinsand.

We hereby anounce that Bitfoo and Bitcoinsand will be closing on October 1, 2017.

Since our new entity INBlockchain has been operating smoothly, this is a new beginning rather than an ending for all of us.

Before we close, you need to know that Bitfoo and Bitcoinsand does NOT support any kind of fork. If you wish to acquire BCC, you can transfer your bitcoins to platforms that supports forks, e.g. Yunbi.

Bitcoinsand will stop sending interests by August 1, 2017.

Please refer to the announcement on Yunbi.com should there be any fork-induced suspension in bitcoin withdrawal.

Bitfoo and Bitcoinsand will stop withdrawal business by October 1, 2017. We will inform our remaining users via phone and email in late September. Any withdrawal later than October 1, 2017 will take at least one week to be proccessed.

All withdrawal business will officially terminate on May 1, 2018.

How to use callback_url & redirect_url

redirect_url

If you fill the redirect_url option, then a button called “return to merchant’s website” will display right after the payment is completed. The button will link to this redirect_url. The entire payment process will be more consistent with this option.

callback_url

Please ignore this section, if you don’t have needs to process your orders automatically.

We offer this option, so that you can integrate the payment button to your own system. While an order is complete, our system will access your callback_url with a POST REQUEST.

Our system will retry 3 times until the request is successfully made, while you should return the parameter _request_check_.

We use a parameter signature (sha1 encrypted) to identify the POST which is from our system.

Our Public Key is:

什么是 callback_url, redirect_url

redirect_url

如果您填了这个选项,那么用户在支付完成后会显示一个”返回商家页面”的按钮,该按钮会链接到redirect_url。有了这个选项以后可以使整个支付流程更加的连贯。

callback_url

这个选项是为了有需要通过程序自动化监控您的订单的需求而设定的。如果您没有这样的需求,那么可以不用了解。

为了方便您和您自己的系统进行整合以及便于管理,我们提供了这个选项,当一个订单完成时,我们的后台会访问您提供的这个url。

系统访问这个url会有重试机制,为了让系统知道请求确实成功了,您在程序上应该原样返回一个参数,这个参数名是 _request_check_

我们采用了签名的方式(sha1)来让程序确认请求确实来自币付宝而并非其他的用户。

个性化比特币地址

币付宝推出了个性化比特币地址定制服务!从今天起,您可以选择您喜欢的字母或数字组合作为个性地址的前端。您可以参考以下范例:

  • 1BifubaoCT6C7teCt4EtDHXiTYyQUZAPkZ
  • 1Love1bUmhSoTXozBRBEtRe8LeF9TGbZBN
  • 12345678Xge3bCCWyLxV86hPStT4EUAWT7

您的个性化比特币收款地址会显示在您的账户中,其他比特币用户可以直接将比特币发送至您的个性地址。币付宝团队已搭建了专门生成个性地址的矿机,您可以在生成新的收款地址时选择属于您的个性地址。

个性地址的价格由您所设置的个性化部分的长度决定(见下表):个性化部分越长,需要的算力就越强,价格也更高。币付宝支持3至8位的个性化定制,生成个性地址的时间不尽相同,下表中的地址平均生成时间仅供参考。个性地址使用人民币定价,比特币收款。


由于我们计算地址的原理实际上是进行不断的生成随机地址并校验,所以我们给出的预计生成时间仅供参考,实际出地址结果的时间也有很大的运气成分。举例说如果你生成一个预计3小时的地址,如果运气好可能1小时就出了而运气不好的话甚至需要12小时。整体而言服从正态分布

个性地址价格表:

个性化部分长度 平均生成时间 价格 (RMB)
1, 2, 3, 4 少于1分钟 6
4 3分钟 12
5 少于1分钟 6
5 3分钟 48
5 3小时 196
6 3分钟 98
6 3小时 388
6 7天 1,680
7 3小时 488
7 7天 1,880
8 7天 2,980

最后更新时间: 2014-03-26

我们会在您输入个性化部分时自动计算出生成该地址所需要的时间和价格。

定制个性地址时有以下5点需要注意:

  1. 每一个比特币地址的起始位为数字1,您选择的个性化定制部分从第二位开始(见范例)。您定制的个性化部分以外的部分随机产生,我们无法进行干预。
  2. 您定制的个性化部分并不唯一,例如,多个用户可同时购买1Love开头的比特币地址。因此,您在发款或收款时应格外注意输入的地址是否正确。
  3. 由于比特币地址的格式要求,我们仅支持字母和数字的组合(字母区分大小写),并且以下数字和字母不能作为地址的一部分:
    • I (大写字母i)
    • l (小写字母l)
    • O (大写字母o)
    • 0 (数字0)
  4. 个性化地址与您的币付宝账户绑定,您只能通过币付宝使用定制地址。
  5. 个性化地址一经售出,无法退款。

希望您喜欢我们的新功能!

Bitcoin Vanity Addresses

You can now obtain your own bitcoin vanity address to use with your Bifubao account! A vanity address is a custom bitcoin address that includes a custom piece of text embedded in it as a prefix. The following are examples of vanity addresses:

  • 1BifubaoCT6C7teCt4EtDHXiTYyQUZAPkZ
  • 1Love1bUmhSoTXozBRBEtRe8LeF9TGbZBN
  • 12345678Xge3bCCWyLxV86hPStT4EUAWT7

People can send you bitcoins directly to this address, and it will show up on your Bifubao account. We’ve set aside a few dedicated miners to calculate these addresses, and you can order them right from your account page when creating a new address.

When you purchase a vanity address, we will directly debit your bitcoin account for the cost. The price for each vanity address varies depending on the length and the difficulty of the custom segment that you wish to have. Take a look at the table below, for reference. As the length of the segment increases, the mining power required to calculate this address increases exponentially. We support the custom prefixes of the lengths sent forth below. Keep in mind that the calculation times may vary significantly from the average time! We base the price on RMB, but we will take payment in bitcoins, of course.

Here is our pricing structure:

Prefix Length Average Calculation Time Cost (RMB)
1, 2, 3, 4 less than one minute 6
4 3 minutes 12
5 less than one minute 6
5 3 minutes 48
5 3 hours 196
6 3 minutes 98
6 3 hours 388
6 7 days 1,680
7 3 hours 488
7 7 days 1,880
8 7 days 2,980

last update: 2014-03-26

It looks complicated, but don’t worry - we will calculate the price for you right as you type in your prefix.

Some things to keep in mind:

  1. Each bitcoin address necessarily starts with a 1. The prefix that you choose will show up directly after this 1, like the examples above. We have no way to predict the letters that come after your selected prefix.
  2. Your particular vanity address is unique, but other people could request the same prefix. For example, many people can purchase vanity addresses that start with 1Love. You should still take care to ensure that you are sending or receiving bitcoins to the correct address.
  3. Because of Bitcoin’s address format, only letters and numbers are allowed, and the following characters are prohibited:
    • I (capital letter i)
    • l (lowercase l)
    • O (capital letter o)
    • 0 (the number 0)
  4. These custom addresses are tied to your Bifubao account. You won’t be able to use these addresses with any other wallet.
  5. The purchases are nonrefundable.

We hope you like this new feature!

CCTV visits Bifubao!

Bifubao was featured in a CCTV segment on Bitcoin! CCTV paid a visit to our humble office in the video and we were able to chat with them about what we are building and Bitcoin. Two of our cofounders, Li Xiao Lai and Pan Zhi Biao were featured. You can watch the segment here.

Thank you to CCTV for coming by and visiting our offices. Come back anytime!

*To correct a misstatement in the segment, we aren’t quite adding one thousand users per day just yet (although we certainly wouldn’t mind!).
