㈠ 比特币前景怎样

近日，勒索病毒“永恒之蓝”席卷全球。攻击者声称，要想解锁被病毒控制的电脑，需要支付等价300至600美元的比特币。因此，这种病毒又被部分媒体称为“比特币病毒”。

根据《2014-2016全球比特币发展研究报告》，目前全球算力的75%以上集中在中国。此报告由清华大学五道口金融学院互联网金融实验室和火币网联合发布。

资料显示，全球矿场目前每小时耗电量大于60万度，每年大于52亿度。有人质疑矿机常年高速运转耗费大量电力，却生产出来“一种虚无缥缈的东西”，是在资源浪费。

但孙小小否认“费电”一说。孙小小说，我国2015年弃电500亿度，他们的矿场在西藏和四川，解决了当地很多弃水弃电，“就地解决，转化成比特币，连铺设电网的钱都省了。”

他眼中，比特币像一场规模宏大的去中心化的社会性试验。他认为，比特币能让整个政府更小、更廉洁。“比特币系统是透明的、可追溯的”，假如整个社会交易体系都采用比特币，“贪官也不敢收钱了”。

比特币专栏作家李健告诉记者，比特币实际上建立了一个去中心化的全球支付体系，与世界各国银行系统或者支付系统转账所消耗的成本相比，比特币的能耗并不算大。

在币圈，税务问题也较为敏感。由于没有法律的明文规定，各家矿场挖到大量“昂贵”的比特币不需要为此纳税。某比特币公司创始人吴钢坦言，目前税务部门只能在其它生产资料比如矿机、电力上收税，对生产出来的比特币并无相关规定。

㈡ shot time(sec)是什么意思

我还可以根据这个字母的话，代表这含义，你就可以翻译过来了呀

㈢ you will怎么解释

这句纳迹话罩运应该还缺个动词,在will的后面,因为difficulty只是名词.原句应该是：nobody knows when you will have difficulty?没人知道你什么时候会遇到困难.这里用you will,因为从句里要用陈洞闷并述句语序.所以是when you will.

㈣ 我的NFT在哪里我怎么能看到它呢

翻译The Comprehensive Guide to NFTs

Where will my NFT “be” and how can I see it? Technically speaking, your NFT will exist on a blockchain supported by a server. For as long as the blockchain exists, your NFT will exist. 

我的NFT在哪里？我怎么能基租看到它呢？从技术角度来讲，你的NFT会存在于区块链上，由服务器做支持。只要区块链存在，你的NFT就会一直存在。

In the case of NFTs that take the form of still images or video clips, you will be able to view your NFT wherever you have a screen or device on which to display it. How people “see” your NFT will largely be up to you.

在NFT还是图片或是视频片段的案搏答兆例中，你能通过屏幕或是设备，来展示NFT。人们怎么能看到你的NFT，还是取决于你。

 But just because an NFT won’t “be” in your house hanging on the wall, doesn’t mean that it won’t be yours, or won’t be secure. (It can hang on your wall, if you wish, and be seen through a television screen, etc.) To the contrary, your NFT artwork may literally be the most secure thing that you own. It will almost definitely be the most secure work of art that you own. As we’ve seen, because the blockchain technology in NFTs literally imprints the history of the work on the work, authentication and provenance can be known instantly. Even with the carbon-dating of canvases, and the discerning eyes of trained art historians, forgeries and fakes can still be passed off as the real thing in the work of physical art. (Or a stolen painting may be “found” years later after a questionable chain of ownership.) But when a piece of art is an NFT, this possibility is eliminated completely.

但是，由于NFT不会被你放在家里挂在墙上，不意味着它就不是你的，或是不安全（它可以挂在墙上，如果你愿意，还可以通过电视屏幕展示）。相反，你的NFT艺术品可能是你拥有的最安全的东西。正像我们看到的，由于区块链技术在NFT上的应用举清，NFT可以展示艺术品的收藏历史，真实性和证明可以被立即查到。即使是给油画做碳14定年法，和艺术品历史学家的敏锐眼光，伪造者依然可以蒙混过关。但是当艺术品作为NFT之后，这种可能性就微乎其微了。

The NFT will “be” on the blockchain, but it will also be yours however you wish to exhibit it.

㈤ 关于分账结算模块

写在前面：

最近负责的分账模块需要优化，国内网站上搜了很多和分账相关的内容，发现这部分比较偏向定制化，现成的系统模块或做的比较好的系统都搜不到原型，所以记录一些有价值的相关资料

When you are building your Software as a Service (Saas) Minimum Viable Proct (MVP), there is a lot of work that needs to be done. It can be difficult to balance this workload.

Oftentimes you are so focused on developing the proct that you forget that you still need to sell it to people. This guide is meant to help you get your billing system off the ground to start making revenue, and show what you should be doing when you are ready to scale up.

Subscriptions are key to an effective billing strategy. The ability to charge a credit card on a recurring basis makes payment more efficient for both you and the customer.

To start selling subscriptions to your clients, you need:

If you don’t have the development cycles to do this, you will be stuck with a painful process of sending invoices manually, giving customers access manually, and adding friction to the on-boarding process.

Offering free trials is considered by many to be one of the best ways to find early adopters of your SaaS.

When someone is given the opportunity to try your proct before committing to a subscription, they are far more likely to become a regular customer.

It is good practice to treat your trial users with the same level of support and respect as you would your paying customers. Not only are they experiencing your proct, they are also experiencing the quality of your service.

At the end of the day, you will end up integrating with an external system to handle these use cases. I highly recommend looking at Stripe because they have an excellent API to integrate with and a wide range of functionalities.

If you don’t want to develop the integration with Stripe yourself, take a look at Servicebot — It comes fully integrated with Stripe and has great Customer Relationship Management (CRM) functionality so you can better manage your customers and subscriptions from a dashboard.

During your early stages, Y Combinator founder Paul Graham says, “ Do things that don’t scale. ” Although this may sound counter-intuitive, this is the best way to grow your customer base before you begin to even think about scaling.

What scaling boils down to is automating the manual processes you’ve found to be effective at growing your startup.

When you’re ready to scale your billing solution, here are a few things to consider:

Automating the processes involved with billing — such as what happens when a user requests a trial, adds a funding source, or requests a cancellation — is one of the most important parts of scaling your billing solution.

You should first take a look at how you are currently doing your billing. Identify all the manual processes that currently are a part of your system, like restricting access if trials expire or reactivating accounts after they’ve been cancelled. Once you make that list you can start figuring out how much time is spent performing these and start iterating to rece the most painful parts.

Another big part of automating your process is automating customer outreach based on their status in the billing system.

Customer outreach is key to converting customers from free trials to paid. When starting out, this process is mostly manual. Email people when they sign up, remind them when their trial is ending soon, or ask if they need help getting started.

This is not scalable — you need to eventually automate this process, and the best place to focus on is the billing side because so many steps are processed there

To ensure seamless communication between your system and the customer, it is important for your system to be tightly integrated with your billing.

One of the best ways to automate your businesses with minimum development effort is to integrate with third-parties who have already solved the problems you are facing.

Here are my favorites which I’m using for my own SaaS startup:

Stripe has become the staple of SaaS payment providers. With a developer-friendly API and constant new features, I (and countless others) feel it’s an obvious integration point.

Some of the features you can integrate with to automate more of your billing are:

There is much more you can do with Stripe, it should be up to you and your startup’s needs to determine how deep of an integration you need.

The staple of Intercom is the live chat widget that you embed on your site to enable communication with your customers. What many people don’t realize is that Intercom also provides an automation platform. If you integrate with Intercom, you can send customized messages to your customer based on what they do with your proct.

This allows you to automate the communication with your customer so you don’t have to manually email anymore.

Example of intercom outreach automation

Servicebot comes out-of-the-box with a Stripe and Intercom integration. When a customer requests a free trial, Servicebot creates a new trialing subscription and customer in Stripe and a new user in Intercom, and directs them to a newly-created instance to use.

Intercom will send automated messages with the goal of converting to a paying user while Stripe will manage the subscription automatically.

A good first step to begin scaling is with automating your billing process. When it all comes together, you can connect parts of your business to a centralized location, as well as integrate it with third parties. The result of all this will be massive gains in proctivity and efficiency that make the effort well worth it.

If you are interested in automating parts of your SaaS billing solution to do things like automate customer on-boarding and connecting business processes to your billing system, Let’s talk

在银行卡收单业务中，以平台对接或“大商户”模式接入持证机构，留存商户结算资金，并自行开展商户资金清算——即所谓“二清”行为。人行以“有没有开展商户资金清算“为标准定义二清。

在网络支付业务中，采取平台对接或“大商户“模式——即客户资金先划转至网络平台账户，再由网络平台结算给该平台二级商户。为客户开立的账户或提供的电子钱包等具有充值、消费、提现等支付功能。

无论是银行卡收单业务还是网络支付业务，以上都叫无证经营支付业务。

二清指的是：线下使用银行卡进行的消费由pos服务提供商收单，然后结算给使用其pos服务的商家。因pos服务提供商无清算资质，所以这种方式属于违规。

网络支付主要指的是：买家支付的货款先到第三方交易撮合平台在支付机构开设的账户，然后由平台结算给平台的商家。因为第三方交易撮合平台没有清算资质，这种也是属于违规。如果由无清算资质的支付机构进行清算，也是不合规的。这点要注意，不是所有的支付机构都有清算资质，目前支付机构中只有银联和网联有清算资质。

本文讨论的主要是网络支付业务的无证经营问题。线下收单业务原理是一样的，只是支付方式不一样。

业务模式为第三方交易撮合（为卖家和买家提供服务/商品等的交易撮合），且资金是大账户模式（先进平台在支付机构开的账户，然后通过平台自己结算给商家）这种都算是无证经营支付业务，是不合规的。

例如：电商平台拼多多、蘑菇街，综合类生活平台美团点评，旅游平台携程等。

无论交易物是实物、虚拟物品还是服务都是一样。只要交易物不是平台自营的，就需要无证经营支付业务问题。

钱包类功能，即能够充值、消费、提现也是属于无证经营支付业务。通过虚拟货币的方式也是不合规的，因为虚拟货币也具有了金融价值，能够等价交换其他商品/服务，如得到的得到币。

严格意义来讲，以区块链技术发行的虚拟币也是不合规的，首先这种虚拟币只能算是一种虚拟商品，其次他的原理同平台发行的虚拟货币是一样的，具有等价交换熟悉。在此不做深入讨论。

政府发布217号文，态度非常坚定，力度也比较大，主要原因如下：

对于新平台来说，无证经营支付业务问题是一定要考虑的问题，不要以为新平台比较小，可以打打擦边球。发现之后可能是会比较严重，这种行为属于明知故犯，有可能导致平台无法继续经营。

建议新电商平台上线伊始就解决二清问题，避免上线后更大的损失。

笔者根据实际的经验总结了目前市面上的方案，并进行了对比，供大家参考。

总体来说，目前市面上的方案分为4类。分别是银行系统方案、微信分账方案、三方支付系统方案、四方系统服务商方案，笔者将分别介绍。

支付宝暂没有分账方案，估计2020年针对支付宝体系内开放分账功能，短时间内应该不会对外开放，目的同微信一样，是为了提高竞争壁垒，毕竟支付宝和微信都自有或投资了电商平台。

通过对比可知，大平台或对系统要求较高的平台可以选择银行系统方案。如果仅仅只是做微信服务号或小程序的可以考虑微信分账功能。对费用比较敏感的可以选择四方服务商系统方案，但是有一定合规风险。比较大众的选择就是三方支付系统方案，门槛适中，合规性没有问题。

笔者研究了上述的四种方案对应的具体产品，分别是平安银行的“电商见证宝”、微信分账、通联“云商通”、投融汇“E帐通”、投融汇“E清算”、投融汇“智富通”（需要开银行实体账户有税费）。供读者参考。

电商见证宝是平安为电商平台提供的支付解决方案，但是实际上客户不仅仅局限于电商，可适用于B2CB2BO2O等多类型的互联网交易平台。于2014年推出，已服务100多家电商平台、产业链客户，可提供整套解决方案，拥有较多成功案例。

应用场景：

电商见证宝服务平台2.0（非自营平台）：

1）子账户类型

平台开立子账户时，分为商户子账户及普通子账户。商户子账户资金只收不付，会员间交易仅支持入账至商户子账户。

2）充值环节

3）退款环节

微信分账功能主要是：为特约商户完成订单收单成功以后的资金分配提供的服务。

应用场景如：停车场缴费、外卖订餐、高校缴费、加油站缴费、预订酒店等。

特约商户 是指：与收单机构签订银行卡受理协议、按约定受理银行卡并委托收单机构为其完成交易资金结算的企事业单位、个体工商户或其他组织，以及按照国家工商行政管理机关有关规定，开展网络商品交易等经营活动的自然人。包括实体特约商户和网络特约商户2种。

实体特约商户 是指：通过实体经营场所提供商品或服务的特约商户，如：商店、饭店、旅馆等。

网络特约商户 是指：基于公共网络信息系统提供商品或服务的特约商户，如自营类型的电商/服务提供商等。

分账可以分给微信支付的商户账户（非银行账户）或者微信支付的用户零钱账户，一笔订单最多可以分给50个分账接收方。

分账资金的冻结期默认是30天。从订单支付成功之日起，30天内需要发起分账，若30内未发起分账，待分账资金将会自动解冻给分账方。

允许服务商分账的最大比例为30%。

通联是一家老牌支付机构，有6张支付牌照。

云商通平台是一个基于虚拟账户和订单支付体系的开放平台，为商户的各类业务场景提供虚拟账户、支付产品和资金管理服务。

通联提供虚拟账户和聚合支付服务，合作银行提供资金存管、结算服务。云商通比较灵活，可根据合作方所在地选择合作银行，可通过分公司对接银行，也可通过通联总部对接银行，定制化程度较高。如果合作银行未与通联合作周期可能较长，需要半年左右的时间才能上线。

通联通过银行存管方式帮助平台解决无证经营支付业务的问题。有3种存管模式：请对接模式一、强对接模式二、弱对接模式。

部分合作伙伴如下：

强对接模式一： 资金通过通联支付进银行账户，银行进行资金结算，结算资金划拨至银行通联备付金账户后，由通联备付金账户付款给商家银行账户。该模式存在一个转代付的问题（通联备付金账户代付），长期来看，如果政策收紧该模式也属于不合规。

强对接模式二： 与强对接模式类似，区别在于代付通过银行直接完成。没有转代付的问题。推荐平台使用该模式对接。

弱对接模式： 该模式特点是平台基本无需开发，适合开发能力较弱的平台。

平台需要在银行开立存管账户，银行帮助平台进行资金结算，平台将结算资金通过柜面划付/网银转账的方式，划拨至通联在银行的备付金账户，由备付金账户付款给商家银行账户。

该模式也存在转代付的问题，且资金只能通过通联账户作为唯一出金路径，需要线下手动操作的工作较多。

投融汇有三种对接方案：E帐通是与通联合作的解决方案，E清算是与招商银行合作的解决方案，智富通是与富邦华一银行合作的解决方案。

服务逻辑图：

投融汇三种对接方案的服务逻辑图相同，详见下图。

以上是作者对4这种方案的理解，供大家参考，如果有问题欢迎大家反馈讨论。读者可根据自己平台的要求和特征选择合适的支付方案进行对接。
