雷诺汽车业务创新经理：会使用区块链技术更好地管理汽车供应链系统

雷诺创新硅谷业务创新经理Sebastien Henot在接受采访时表示会选择区块链技术更好地管理汽车制造商的供应链系统。“区块链的高透明性和不可篡改的特点可以为供应链管理节约成本，这对汽车召回事件至关重要。而这一过程也可能标志着汽车将获得一种独特的数字身份。”

We're all excited for self-driving, even autonomous, cars, and many tout blockchain as the technology needed to make that happen.

But while that conversation is an exciting one today, CoinDesk's Consensus 2018 conference played host to an array of esoteric use cases for the mobility space that showcase how many executives in the automotive space are currently taking a more conservative approach to applying blockchain technology to the industry.

Sebastien Henot, manager of business innovation at Renault Innovation Silicon Valley, is such a pragmatist, opting for the low-hanging fruit of using the technology to better manage carmakers' supply chains.

"Blockchain can bring cost savings to supply chains thanks to new levels of transparency and auditability, which would be of vital help in the unfortunate event of recalls," Henot told CoinDesk.

And that process could also mark the birth of automobiles with their own unique digital identity.

"If you have an Audi and you want to sell it to buy a Renault, it would be very useful for the Renault dealer to be able to access the Audi birth certificate and see a standardized history," Henot said.

But it's still early days, and the process for what kind of data will be shared and how that data will be coded still needs to be standardized.

That's one of the reasons the Mobi consortium, a kind of standards body for decentralized mobility and data sharing, was launched earlier this month with founding members including BMW, Ford, General Motors and Renault, as well as technology providers like IBM, ConsenSys and IOTA.

And while the futuristic use cases made possible by tokenized incentive structures is indeed what interests many members of the consortium, Henot said:

"My philosophy is let's start small."

Blocks of miles
According to Henot, starting with the little things, such as certifying the mileage on a car, highlights a very simple, yet beneficial proof-of-concept.

Odometer fraud, or "clocking," whereby vehicle sellers or dealerships tweak the odometer to make it seem that the car has been driven less miles than it actually has, which can increase the value of a vehicle, is not a new problem (other blockchain-based startups have begun developing systems for just this use case).

In fact, around 450,000 vehicles are sold each year with falsified odometer readings, resulting in a cost of more than $1 billion annually, according to a National Highway Traffic Safety Administration study.

As such, Henot believes the blockchain could eliminate this issue around mileage, "so nobody can tamper with it."

The team at UK-based Dovu, a startup part-owned by Jaguar Land Rover, agrees. The startup raised more than $13 million, according to current metrics, in a crypto token sale in October 2017, which it will use to incentivize users to behave in a virtuous manner, such as capturing mileage of their vehicles on a regular basis.

Dovu began a mileage capture pilot three months ago with BMW, which enlisted its employees to carry out the test using a simple Dovu-developed crypto wallet.

Explaining the benefits of the system, Dovu CEO and founder, Irfon Watkins told CoinDesk, "If, like BMW, you own a lot of cars under a fleet management arrangement, it's really useful to know how many miles those cars are travelling every week or every month - rather than every three years."

He added:

"By which time you might find you have an asset on your books worth a lot less than you thought."

Crypto for the environment
Another small step the automotive industry could take to harness the power of blockchain revolves around electric cars.

Dovu is at the forefront of this application as well, using its token as a way to nudge drivers to charge their battery in an optimum way, "that doesn't degrade the battery, as if it were a mobile phone," said Watkins.

This use case could potentially push blockchain technology into the mainstream narrative, since so many people, especially millennials, are interested in electric cars for their positive environmental impact.

Spherity, a startup founded by a former technology innovation lead at the largest German utility company, Innogy, is also looking at applying blockchain to electric vehicle charging. The company wants to use the technology to provide an audit trail for "greenhouse gas accounting," so users can trust their vehicles are using green energy (hydroelectric, wind farmed or solar) as opposed to energy generated by burning coal.

Just like people might want to track and trace sustainably-produced food from farm to fork, so too will environmentally-conscious users want a "guarantee of origin" on the electricity their car is using, Spherity founder Dr. Carsten Stocker said.

He added:

"Someone who spends $150,000 to buy a Tesla would probably like to have proof they are charging with green energy."

More than just cars
Still, even while some are starting small, many are fascinated by the future as imagined with blockchain.

For instance, Henot said the future of mobility is not only about making vehicles physically autonomous but also economically autonomous, whereby automobiles "speak together, negotiate rights of way, parking and so on, using their wallets."

One such group working towards those cutting-edge applications is the non-profit foundation, Decentralized Autonomous Vehicles (DAV), which describes itself as "the TCP/IP of connected mobility." But according to David Fraser, a co-founder of DAV, one of the reasons the foundation is able to inspire such excitement is because it doesn't think about autonomous vehicles only as cars and trucks.

"There are many other examples such as autonomous drones, autonomous rovers (a drone that stays on the ground) and autonomous marine vehicles - some are already here, the rest are coming," Fraser said.

Among its notable advisers are the former CTO of General Motors, Dr. Alan Messer, as well as the technical lead on the ethereum virtual machine, Dr. Greg Colvin.

Similar to Mobi, DAV is proposing a commons, a standard of sorts, in the form of a free and open-source decentralized mobility network.

And with this, the foundation hopes to see the full potential of blockchain bring about social change within the mobility industry.

According to Fraser:

"Big players are controlling a lot of what is going on right now, but as new and open networks roll out, the silos will be shared and the gatekeepers will become irrelevant."

澳大利亚总理Turnbull指示政府机构研究区块链



澳大利亚总理Malcolm Turnbull已经指示政府的数字化转型机构（DTA）研究区块链技术在政府中的潜在应用。澳大利亚出版物ITNews报道，DTA首席数字官Peter Alexander在星期一晚上向参议院评估委员会发表讲话时透露，总理Turnbull直接告诉该机构，在对其他机构和供应商的技术感兴趣后，探索区块链应用。DTA是在2015年建立的政府机构。Alexander在向参议院财政和公共行政立法委员会发表讲话时还谈到了最近联邦预算中拨给DTA的资金，指出：“总理事实上写信给我们的部长（数字化转型的助理部长Michael Keenan），并要求我们关注区块链，这后来演变成了一项特定的工作。”

Following interest from agencies, vendors.
Prime Minister Malcolm Turnbull directed the Digital Transformation Agency to investigate potential applications of blockchain technology across government.

In senate estimates overnight DTA chief digital officer Peter Alexander revealed the exploration of blockchain technology - and subsequent funding in the recent federal budget - had been requested.

“The Prime Minister in fact wrote to our minister [assistant minister for digital transformation Michael Keenan] and asked us to have a look at blockchain, which evolved into this particular piece of work,” he said.

Alexander said this had been prompted by “a number of conversations with ministers and officers, and that a number of agencies had commenced looking at blockchain”.

“ASIC [was] looking at blockchain, Immigration – now Home Affairs – was looking at blockchain and considering it, and more agencies were talking about it,” he said.

“Lots of vendors were [also] coming to government and talking about blockchain.”

The DTA was handed $700,000 in this year’s federal budget to find uses for blockchain technology over the coming year.

Alexander said this would involve the agency understanding how blockhain can work and whether there “really is a value proposition for government”.

It has already indicated that welfare payments will be a target of its investigation, drawing upon the existing application of the technology in both public and private sectors.

But Alexander said the agency was also looking at blockchain for the “settlement of trades, cargo management and even the providence of open data to ensure that it is accurate”.

The agency has also commenced a separate project with the "Commonwealth Bank and a number of players to have a look at how blockchain might work in the financial services sector".

Govpass moves forward

Alexander also revealed that a total of eight Govpass digital identity pilots were expected to take place during 2018-19.

The first pilot – for the Australian Taxation Office’s new online tax file number application service – will launch in October this year.

“We expect around 100,000 people will use that from October to the end of the financial year, Alexander said.

Other services “for students, for welfare recipients and businesses” are currently being considered by government.

The agency received $92.4 million in this year’s budget to “accelerate” the delivery of its Govpass digital identity platform.

Alexander said the funding would allow the agency to move from "policy development, discovery, problem solving, and alpha prototyping to a live beta where it will test [Govpass] with actual citizen's and business' digital identities."

“During this year that funding will allow us to deliver that digital identity service ... to almost 400,000 Australians to use and test as we plan to scale that out much more broadly," he said.

About 2.8 million transactions will eventually move online as a result of Govpass.

5月22日行情分析：一口吃掉6个亿，稳稳的幸福
5小时前 来源：数字货币趋势狂人



有人在币圈亏了几千万，但并不是因为玩空气，而是因为加了杠杆，玩了期货，玩期货无论赚多少，亏多少在金融行业都不是新鲜事。

狂人说

币圈大佬，我只服李笑来，上的了厅堂，下的了厨房，能在发行和站台无数个ICO项目后成立政府类的杭州区块链投资基金，还能在央视上非常权威的发表自己的言论，真是让我等币圈老人刮目相看，这种社交能力值得我们后辈的学习，相比之下，很多行业老人还都游走于法律的边缘，生活的战战兢兢，这是多大的差距啊。

有人在币圈亏了几千万，但并不是因为玩空气，而是因为加了杠杆，玩了期货，玩期货无论赚多少，亏多少在金融行业都不是新鲜事。

有人在币圈赚了上亿，那是因为他发了币，将自己的后半生贡献给了币圈，这笔巨款赚的也并不一定容易，而是实实在在的奉献。当然，上了央视的太空链，英雄链等诸多空气币也赚了不少钱，但却没有听到后续报道罪犯落网的消息。两种发币的人是完全不同的初衷，更是完全不同的动机，不应该一致对待。

狂人从2013年进入币圈以来，每每看到央视说比特币泡沫，都会暗暗窃喜，因为泡沫哪哪都有，但这里风景独好。

有时候，人很容易当局者迷，你目前所处的生活状态，或许很不好，但却在不知不觉中已经触底，只要你还能够阳光灿烂的微笑面对，触底反弹只是必然，就像我们永远不知道在去年94迷茫恐惧的氛围中，是比特币历史上最好的抄底机会之一。因为我们在剧情当中，只能做到配合出演，有时候，跳出所处的思维，做一个看戏的人，会解开你心理长久的困惑。希望关注狂人的每个人，都处在上升或者准备上升的路上，因为最坏的年代已经过去，未来的币圈，迎接我们的，将是一片新蓝海。

我不太清楚这个规律会持续多久.我经常会和周围的小伙伴说,要敬畏市场.之所以如此,是因为当大家都在考虑何时实现财富自由的同时,而我却考虑着如果市场再次出现13年那样的长期熊市,我该如何应对.

这两天有幸认识一个币圈的老司机,一个13年的玩家,闲聊之余,我再次问起当年13年的情况,事实上这个事我问过好几个人,基本上都是异曲同工,但是我特别喜欢去关心这些,因为我知道我早晚也将面对.

这次老司机和我说,13年的大熊市基本上已经不是用凄惨所能形容,当时LTC从375跌到了5块钱,这位小伙伴虽然是老司机,但也在90附近接了盘,被套了三年才脱了身.

我听完以后仔细想了想,说实话,被套那么长时间,我严重怀疑自己是无法扛过来的.同时我也相信90%以上的人是抗不过来的.

币圈黄埔军校 OK你到底送走了多少人？
14小时前 来源：吴解区块链  803
短短几年间，已经有多位币圈大佬从OK这个黄埔军校中出走
自从接触了区块链之后，深刻领悟到“链圈一天，人间一年”这句话的含义，圈内风云变幻的速度真的快，快得让我有点一脸懵逼。

今早突然爆出来，原OKEx的CEO李书沸今天正式加入火币集团，担任董事会秘书和国际商务拓展副总裁。等等——如果我没记错的话，号称币圈吴彦祖的李书沸发表离职声明好像才刚刚一个星期？



5月14日发表的离职声明，字里行间透露着一种“只施展了一部分抱负”的遗憾，读起来还颇有些委屈和心酸。一周还没过完，火币集团创始人李林就在集团内部发表了一篇欢迎李书沸入职的公开信，信中透露了几个信息：

1、李书沸离职当天火币便与他取得了联系，并以光速达成了合作意向；

2、李书沸拥有的银行、投资和上市公司运营管理经验，是火币最仰仗的财富。

虽然链圈一天，人间一年，但在如此短时间内加盟另一家同行业竞争对手公司，真的不违反竞业协议吗？

竞业协议中明文规定：根据法律规定或用人单位通过劳动合同和保密协议禁止劳动者在本单位任职期间同时兼职于与其所在单位有业务竞争的单位，或禁止他们在原单位离职后一段时间内从业于与原单位有业务竞争的单位，包括劳动者自行创建的与原单位业务范围相同的企业。

果然不出所料，徐明星随后就在朋友圈开始回应：让我们以法律手段来解决这个离职问题。



乍看这是一篇看似充满祝福的回应，但言语间已经把“李书沸单方面辞职加入火币”的不满卖了个精光，被竞争对手直接挖了CEO，这搁谁谁都下不来台。你以为这就是全部了吗？并不，李书沸也不甘示弱，立马翻脸喊冤，怒怼徐明星并非明主，OK管治不力，导致初代团队相继离开，自己问心无愧苍天可鉴，换东家只是为了梦想。5个问句把委屈而又不满的情绪安排得明明白白。



精彩啊精彩，真 · 币圈每天有大戏系列！最厉害的是，赵长鹏、何一、雷臻、陈欣、段新星等这一长串如雷贯耳的名字如此密集地出现，居然都是跟“离开OK”有关。这让人不得不惊讶，OK，这个币圈赫赫有名的黄埔军校，短短几年间，到底送走了多少人？

赵长鹏

在赵长鹏之前，“OK黄埔军校”也只是圈内人的说笑而已，但在赵长鹏和他的币安之后，这个名字算是彻底响亮了。



赵长鹏在OK的那一年里频繁为东家站台，用他当时的话说：“我认为OKCoin是目前全世界最好的比特币交易所！”确实，铁三角组合在当时被圈内称为“比特币天团”。

但这种温情脉脉并没有持续多久，2015年6月，因为合同造假事件，赵长鹏和公司相互攻击，最终以他的离职惨淡收场。到了2017年，蛰伏已久的赵长鹏已经有了更深的想法，他想要一个处理交易能力更强、更安全的平台，就这样，币安，横空出世。

2月份的时候，赵长鹏登上过福布斯封面，10个月前还不存在的币安，现在已经成为了全球最大的加密货币交易所；而从一名“码农”变为福布斯数字货币富豪榜上的亿万富翁，他只用了半年。

你说他是传奇人物一点都不为过。

何一

在赵长鹏2015年5月退出OK后，何一不久也选择了离开。再次创业，赵长鹏盛邀旧时搭档入伙，这位85后高颜值女青年摇身一变，成了如今大名鼎鼎的币圈一姐。



何一在一次采访中透露，“在挖我的过程中，他（赵长鹏）是在找合伙人，而不是找员工，很重视团队的沟通和反馈，是一个好的管理者；他对中国市场的理解有限；但这部分是我熟悉并且擅长的；当年是我挖他，现在他挖我也算扯平了。”

从旅游卫视主持人，到币安联合创始人，明明可以靠脸却偏偏要靠实力吃饭，在比特币这个男人主导的行业里，币圈一姐克服性别劣势，凭借自身的聪慧和勤奋，打下了半壁江山。

段新星

对链圈人士来说，比原链是国内最著名的区块链项目之一，有着明确的应用场景和优秀的技术团队。而它幕后的那个男人便是从OK出走的段新星，现任比原链创始人和巴比特执行总裁。



据他所说，他加入巴比特也是理念和时机的双重契合。由于个人原因，段新星想回到南方发展，“刚好遇到长铗，理念比较投合，也很看好公司的未来发展，所以踏上这条‘海盗船’。”再一不小心就搞出了比原链……

以上还都是目前币圈非常熟悉的人物，而像雷臻啊陈欣啊，出走OK后都纷纷开启了交易所，与老东家OK共饮一瓢水，共分一杯羹。可以说中国比较有名的交易所里，都或多或少有着OK的影子。

短短几年间，已经有这么多币圈大佬从OK这个黄埔军校中走了出来，李书沸所说的“管制不力”也似乎有迹可循，想也知道徐明星的心理阴影面积有多大了。他自己应该也万万没有想到，本来只是想做个企业，结果最后带出了半个圈子的行业大佬，也是没谁了。

不说了，我准备去OK深造了。

以小博大的杠杆交易：天使OR魔鬼

1天前 来源：币晓区块链  534

杠杆交易是一柄双刃剑，与高收益相伴的无疑是高风险，如果投资人入市点位稍有偏差就可能带来巨大的损失。
5月6日以来，币王比特币由10000美元高位持续下跌，至5月18日一度跌破8000美元心理关口，直逼7900美元，累计跌幅已逾20%。其余币种多是惨不忍睹，跌幅远超比特币，打回原形者不计其数，导致小散们资产大幅缩水。

为挽回损失，一些小散选择增资加码，以期通过增量资金抄底获取丰厚盈利。其实，在这种情况下增资不是唯一选择。现在有不少交易平台都推出了类似融资融券的杠杆交易，为投资者提供了将收益放大数倍的工具。2107年底至2018年2月，华尔街资本就是利用比特币期货加上数倍杠杆，从数字货币市场掠夺近2300亿美元。

在数字货币市场，杠杆交易是衍生金融工具，是指将自有资金抵押给交易平台作为保证金，从交易平台借出数倍于自有资产的资金或数字货币，并在规定期限内将其交还交易平台的投资模式。投资者可以根据自己风险承受能力，选择杠杆倍数，通常为20倍以内，也有的交易平台杠杆倍数高达50倍。通过使用杠杆交易，能够增加可交易资产，享受高投资的收益回报，但同时也要承担相应的高风险。

投资者仅用自有资金交易，则只能做多，无法做空。而利用杠杆交易，则既可做多，也可做空。



如果认定投资标的会在未来一段时间内呈上涨走势，则可将账户自有资金，假设为200USDT，通过杠杆交易账户下的杠杆管理，抵押给平台后借出200USDT，这时账户投资额度就变为400USDT，当投资获利后，将借来的200USDT归还平台，并缴纳一定的手续费即可。在做多交易中，需要承担币价可能下跌的风险，一旦下跌幅度过大，触及到保证金的最低平仓线，将面临本金全数亏损的可能。

同理，如果预测投资标的未来会出现下跌行情，则可将账户自有资金抵押给交易平台，然后借出等值或者数倍的数字货币，以当前价格卖出，等待下跌后再买入归还给交易平台，赚取的是币价下跌后的差价。在做空交易中，需要承担币价可能上涨的风险，一旦上涨幅度过大，触及到保证金的最低平仓线，同样将面临本金全数亏损的可能。

使用几倍杠杆交易，收益就会扩大几倍。以BTC交易为例，如果判断比特币币价会从6000 USDT 上涨到10000 USDT，如果只有本金6000 USDT，在5倍杠杆下，可向平台最多借30000 USDT。这时可用36000 USDT 以6000 USDT 的价格买入6枚BTC，并以10000 USDT卖出，盈利为24000 USDT。而如果仅用自有的6000USDT 全仓交易，仅可盈利4000 USDT。如果预计比特币币价会从10000 USDT 下跌到8000 USDT ，假设自有50000 USDT ，在3倍杠杆下，可向平台借15枚BTC，以10000 USDT 价格卖出，在8000 USDT 买入，盈利30000 USDT 。



杠杆交易中盈亏都将被数倍的放大，风险性极高。如果判断出现偏差，亏损一旦触及到保证金交易的最低平仓线，且未能及时补足抵押保证金，交易平台通常都会采取强行平仓的方式进行交易结算，即抵押给交易平台的保证金将全数亏损。除此之外，杠杆交易还需要每天都缴纳给交易平台一定的费用。

据新闻报道，币市有不少散户利用交易平台杠杆工具进行交易，多数处于亏损状态，盈利者寥寥无几。如2013年11月至2016年6月，一位陈先生投资321966元，通过火币网交易平台，进行20倍杠杆的比特币、莱特币交易，最后账户仅余104772元，亏损217194元。有鉴于此，奉劝小散们不要轻易将全副身家都压在杠杆交易上，合理利用这种以小博大的工具，必须做到：避免满仓杠杆交易，避免长周期使用杠杆交易，严格执行止盈和止损纪律，尽量备有足够现金流，当市场突发震荡时及时补仓。

杠杆交易是一柄双刃剑，对于水平高的投资者而言，在严格控制风险的前提下，盈利或浮动盈利 可以继续利用高杠杆增加仓位，为实现暴利提供了可能。但与高收益相伴的无疑是高风险，如果投资人入市点位稍有偏差就可能带来巨大的损失，对于小散而言首先要考虑的应是风险，而不是获利。

巴塞尔大学开启区块链验证学历项目

据Finance Magnates消息，瑞士巴塞尔大学创新金融中心（CIF）与区块链创业公司Proxeus宣布合作一项新的以太坊项目用于保护和验证学历。CIF董事总经理Fabian Schär博士称通过在区块链上获得证书，使得毕业生和潜在雇主可以得到额外的安全保障，这些证书不能伪造并且可以在线验证。



A new project in Switzerland is to protect and verify academic credentials using blockchain technology. The project comes from a partnership between a national university and a fintech startup.

One partner is the Center for Innovative Finance, a research group within the University of Basel which focuses on financial technology. According to the official website, one of its remits is to analyse the pracitcal implementation of blockchain technology “also in the context of societal consequences. In pursuing these objectives, great importance is attached to comprehensive, interdisciplinary analysis.”

The other is a company called Proxeus. “By making blockchain accessible to the average user, Proxeus will enable previously paper-bound, traditionalist businesses to easily digitize and adopt new blockchain-based business models,” says its website. The company was founded in 2015.

The new service is built on the Ethereum blockchain. According to an a letter from the university, it works by registering course completion certificates on the blockchain with a unique hash code. The CIF will be the party that will verify and register certificates. Another tool will be made available to the general public, which people can use to check if a given certificate is valid.

Dr. Fabian Schär, Managing Director of the CIF, said: “Fraudulent documents are a problem in academia just as it is in any field. By securing credentials on the Blockchain, we provide an extra layer of security for graduates and potential employers. These credentials can’t be faked, and can be easily verified online. It will introduce a new paradigm of security and offer value to all parties – employers don’t lose time checking
Seite 2/4 credentials, graduates have an edge, and the institutions themselves reduce their reputational risk and a significant administrative burden.”

Antoine Verdone, CEO of Proxeus, said: “We are particularly proud of this project. Proxeus has been intended from the beginning to
be easy to use, efficient, and Blockchain agnostic. In less than a month, we have deployed two functioning prototypes on two different Blockchains – and this one took less than a week to take from concept to completion.”

Last week we reported that the Swiss government is considering a state-backed national cryptocurrency, the ‘e-frank‘. The country’s central bank does not agree; in the opinion of one member of the governing board, a national cryptocurrency would not only not be advantageous to the economy but could actually threaten stability; cryptocurrencies should remain private sector endeavours.

Blockchain database technologies will power tomorrow's internet of things—and that could include the Navy's onboard weapons systems.

Bitcoin’s meteoric rise in 2017 made “blockchain” a household word. But Bitcoin is only one outlet for the application of the basic database architecture called blockchain. A much more important application just over the horizon is the internet of things (IoT). And the most deadly IoTs of all could be the Navy’s next generation of surface-combat ships.

How could a database technology run a battleship?

A typical U.S. surface combatant like an Arleigh Burke-class destroyer combines powerful radar systems with ninety or more missile launch cells (each one capable of launching one of a dozen different missile types), two independent Phalanx close-defense systems, and six torpedo launchers, not to mention a five-inch gun, several machine guns, and a host of other weapon systems.

The challenge is to make all these combat systems work together without blowing up the ship. America’s opponents have often fielded bigger, badder weapons than the United States, but the secret to naval success is systems integration. As the British proved at Jutland in 1916, superior fire control trumps superior firepower.

For the U.S. Navy, systems integration still means the aging but effective Aegis Combat System. Now in its fifth decade of operation, Aegis is a centralized command-and-control system that links sensors and weapons like a boxer’s brain links eyes and fists. But that very centralization is also a weakness. Knock out the brain and you knock out the boxer.

Enter blockchain.

Blockchain technology lays the foundation for the distributed database management and decisionmaking. A blockchain is what it sounds like: a series of blocks of data that are chained together in linear sequence. The sequence is maintained by a link called a hash—a scrambled code that takes the entire contents of a block of data and converts it into a 256-bit reference number.

Every time a new block of data is added to a blockchain database, it starts with a hash of the previous block. Since the previous block started with a hash of the block before that, and so on, the entire history of the database is distilled down to the current hash.

If you know that current hash, then you can’t rebuild the blockchain. But you can verify whether your version of the blockchain database is the same as someone else’s. If you both have the same hash, then you both have the same database. You don’t have to check trillions of lines of data to make sure they’re all identical. You just have to check the final hash.

The verifiability built into blockchains through their hashes means that people—and more importantly, devices—can coordinate their behavior by exchanging just 256 bits of data. If you need millisecond decision-making, blockchain is for you. And that's exactly what the Navy needs for its next generation combat systems.

Using a blockchain database architecture, the Navy can structure its next-generation combat systems around decentralized decision making nodes. That will speed up fire control while (crucially) improving survivability. Like the civilian internet we all use every day, an onboard blockchain-powered internet of things could keep functioning in a coordinated way even when the central computers go down.

Before the dreadnought revolution of the early twentieth century, naval firepower was essentially decentralized, with each battery firing more or less independently. Centralized fire control systems, first on each ship and later across whole squadrons, gave the British Royal Navy and then the U.S. Navy an overwhelming offensive advantage over their adversaries. But it introduced new vulnerabilities at the same time.

Decentralization with coordination keeps the advantages while reducing the vulnerabilities. Blockchain makes that possible because it provides a mechanism for multiple independent systems to instantly verify that they are working from the same “understanding” of the world. Independently operating artificial-intelligence processors loaded on different weapons systems can coordinate their actions because they can verify that they’re working from the same data. That’s the blockchain advantage.

Back in the twentieth century, processing power was expensive but data was cheap. That’s why in 1969 it made sense to centralize onboard decisionmaking in a single Aegis brain. Today, processing power is cheap and data is at a premium. That’s why the Navy’s twenty-first century combat systems are likely to run on blockchain.

智利总统称要对数字货币进行监管



据Bitcoin.com消息，智利总统马塞尔（Marcel）发表评论称他的政府正在考虑成立一个立法机构，旨在监管智利数字货币行业有关的活动。
马塞尔先生指出：要纳入一项法规对数字货币相关活动的参与者进行登记，从而掌握信息来监控相关风险。相关法规可以根据更加健全的标准和机制制定，特别是在市场透明度、消费者保护以及防止洗钱和恐怖主义融资方面。
据早前消息，这与3月份智利国有银行对数字货币交易所的态度相反。3月底，智利国有银行Banco del Estado de Chile通知数字货币交易所Orionx、CryptoMKT和Buda.com的账户将在10天内关闭。

The Chilean president, Mario Marcel, has made comment seemingly in favor of developing a regulatory apparatus for virtual currencies. The apparent openness to regulating cryptocurrencies contrasts significantly from the recent banking embargo targeting virtual currency recently witnessed in Chile.

马绍尔群岛签署法案，推出加密数字货币作为主权货币







CNBC Cryptotrader主持人Ran NeuNer在Twitter上称，联合国成员国马绍尔群岛签署了一项里程碑式的法案，将其主权货币（sole sovereign currency）定为一种加密数字货币，这意味着该国数字货币合法化。该国银行等机构必须支持该种数字货币。

Tweeting earlier today, Ran Neuner hinted at a ‘HUGE NEWS’ announcement on his show – Crypto Trader on CNBC Africa.

As Neuner postulates, banks/Visa and other financial intuitions will have to now accept that cryptocurrency is a legal tender of a sovereign nation. This marks a gigantic step forward for the space as a whole. Details are yet to fully emerge regarding the technological underpinnings of the sovereign digital currency, and whether a commercially-backed project is providing the necessary infrastructure support. More can be seen about this breaking development here.

2018 is the year that commentators from all sides have predicted industry adoption. Now that a nation has adopted cryptocurrency as its national currency, the speed of further adoption is likely to increase. Could this also mark the end of the markets general downturn? It seems that with current efforts with the securitisation of assets, as well as private and central banks discussing issuing further assets and providing trading platforms amongst other liquidity, an upturn is hopefully just round the corner.
