Think Tank Tells Swiss National Bank to Launch Swiss Franc Token, Embrace DLT

What can I do to prevent this in the future?

If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.

If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.

Retail Giant Carrefour Saw Sales Boost From Blockchain Tracking

French retail giant Carrefour has attributed a recent increase in sales to its use of blockchain tracking.

Carrefour’s blockchain project manager Emmanuel Delerm told Reuters on Monday that the use of blockchain ledger technology to track meat, milk and fruit from farm to supermarket has increased sales of these products.

According to Delerm, blockchain tracking has been particularly successful in China, where shoppers are more used to scanning QR codes. The initiative likewise proved to be popular in Italy and France, where buyers reportedly spend as long as 90 seconds reading merchandise information.

With the firm’s blockchain tracking – built with IBM Blockchain – customers can scan a QR barcode on a product with their phone and obtain information such as its date of harvest, farm location and owner, packing date, how long it was transported, and tips on how to prepare it.

“The pomelo [a citrus fruit] sold faster than the year before due to blockchain. We had a positive impact on the chicken versus the non-blockchain chicken,” Delerm said.

Carrefour initially launched blockchain information for 20 items, including chicken, eggs, raw milk, oranges, pork, and cheese, according to the report. Now, the retailer intends to add 100 more products to the system, particularly focusing on products for which consumers want reassurance, such as baby and organic products.

The tech creates a “halo effect,” meaning if shoppers feel they can trust one Carrefour product, they will also trust other items, Delerm said.

There are still challenges to blockchain tracking however – particularly in tracking fruit and vegetables sold loose and sourced from a number of farms. There is also some resistance from farmers to sharing too much information, according Delerm.

Carrefour is also working with Nestle, allowing the Swiss food and drinks giant access to its blockchain data for its Mousline potato puree so buyers can see that the produce is sourced from French farms

EOS Polls Show Overwhelming Support for Slashed Inflation Rate

EOS Polls Show Overwhelming Support for Slashed Inflation Rate

According to an online poll result released on June 1, 2019, statistics show that EOS account holders have voted in favor of a massive slash in the annual inflation rate, from five to one percent.

The poll comes as a result of the excess inflation rate accumulated over time on the platform’s account.

EOS Community Votes for 1% Inflation Rate

With a current annual inflation rate of five percent, four percent of that inflation rate was sent to the eosio.saving account, while one percent went to block producers (BP) who run the network. With 3.6 million EOS tokens stored monthly on the account, March 2019 saw a total of 28.75 million EOS tokens.

Furthermore, the figure has steadily increased due to compounding inflation, which could make the network vulnerable to hackers.

Giving the reason for the proposal, the publication stated:

“This large quantity of accumulated tokens has now become excessive and if we continue to allow it to keep growing, it will eventually become an attack vector for the network. It is therefore time to turn the tap off and reduce the level of inflation down from an unnecessarily high 5% to a more reasonable 1% by cutting out the 4% that’s being generated and sent to the eosio.saving account.”

The smart contract platform then opened an online poll 88 days prior, to determine if holders were in favor of the reduction in the annual inflation rate, or against the proposal.

After nearly three months since the beginning of the polls, the results revealed that out of 778 EOS accounts, only 2.7 percent participated. Furthermore, the community was generally in favor of a reduction to one percent, following a 100 percent approval.

The implication of the community’s agreement to slash inflation rate means that it might diminish the incentive for hackers to attack the network.

Cashing in on the Buzz

However, the publication maintains that a one percent inflation rate reserved for block producers remains. Thus, the community might need to compromise and set the rate at above one percent to preserve the incentive for block producers.

As recently reported by BTCManager, Block.one announced plans to launch a blockchain-based social media platform, Voice, that would run on the EOS blockchain.

Also, the controversial stablecoin Tether (USDT) revealed its intentions to launch on the EOS blockchain platform. Furthermore, the largest cryptocurrency exchange platform in the U.S., Coinbase announced towards the end of May 2019 that addition of EOS on its platform.

Back in March 2019, a cryptocurrency ranking released by the Center for Information and Industry Development (CCID) in China showing the top ten cryptos placed EOS as the number one virtual coin.

Secure Your Crypto Accounts With a Physical Key

A physical security key is a piece of hardware used for verifying you have permission to access sensitive online services. It can be used for securing accounts on cryptocurrency exchanges employing two-factor authentication, replacing more vulnerable methods such as receiving verification codes via SMS. It greatly reduces the risk of hackers remotely taking over your account with cyber attacks such as phone porting, as they now need to have the actual device in their hands to gain access to your account.

One such physical security tool for crypto exchange accounts is Yubikey, which supports platforms such as Bitbay, Bitfinex, Bitmex and Kraken, among hundreds of other services. It is a line of small USB devices that fit into your computer and verify authentication with the press of a button. Many more platforms can be used with these tools and Coinbase exchange recently announced it is also gradually rolling out support for universal second factor security keys to its users, calling them “the gold standard of modern account security.”

火星一线 | 波场孙宇晨:拟邀吴忌寒、李林、Vitalik共赴巴菲特慈善午宴

火星财经APP(微信:hxcj24h)一线报道,波场TRON创始人孙宇晨于今日凌晨在微博中表示,其本人已成为第二十届“巴菲特慈善午餐”的最终竞拍赢家,以创记录高价456.7888万美元(约合人民币3154.03万元)——较2018年的3300100美元高出1267788美元—— 拍下“巴菲特慈善午餐”。

据新京报透露,目前孙宇晨与巴菲特约定的慈善午餐时间为第三季度、地点初定为旧金山,拟邀请比特大陆吴忌寒、火币网李林、以太坊创始人Vitalik等共同参加。

同时,孙宇晨强调,此举并非“炒作”,并表示去年因故错过竞拍。

针对此次午宴,他表示:“午餐会的最重要话题是希望修正巴菲特价值投资理论,目前巴菲特对比特币等加密货币有偏见,希望通过交流会可以让巴菲特了解区块链和加密货币”。

然而,他随后指出,“不指望能扭转或改变他的看法,三个小时不可能改变,这个午餐会是交流会”。

火星财经APP(微信:hxcj24h)了解到,孙宇晨曾邀请币安CEO赵长鹏参加巴菲特午宴,不过其因个人原因谢绝了此次邀请。

赵长鹏在推特中透露,“孙宇晨已经邀请我了,但是太远了,我没办法过去,不过我强烈建议邀请Morgan Creek Digital联合创始人Anthony Pompliano”。

截至发稿,TRX报价0.035美元,24小时跌4.21%。



火星财经特约分析师蔚蓝:短线调整到位,满仓以待,勇者无惧

上海、重庆、三亚、武汉……4个周末,蔚蓝分别和4个城市的区块链从业者以及投资者做交流。4周下来,形成几点认识:

1.仍有不少项目方和Token Fund是懵逼的,有一万个理由相信仍是熊市。

2.多个渠道,多个机构,在场外和场内扫货BTC,都是几千上万的买入。蔚蓝听到的一定只是一小部分。

3.股市操盘手和配资机构手拉手入场,这些兄弟只有一个信念——牛市已经开始,赶紧扫货上车。

4.少量先知先觉大妈开始入场。(本人对大妈绝不歧视,事实上在中国房地产市场赚钱最多的都是大妈、大爷,刷抖音刷傻了的白领才是反向指标)

周日以来,市场画风突变,盘整多日的BTC选择大幅下跌,大幅上涨后BTC下跌并不可怕,可怕的是普跌。不过到今日观察盘面,可以发现USDT场外溢价创出新高,次新币如蔚蓝此前多次提示得ONE、LEO逆势上涨,表明场内做多资金勇者无惧,在市场略有动摇之时,积极行动。

看下绝代双骄——BNB-FT,均下探30日线,短期无虞,近期次新币正在抢过两者的风头,预示着场内积极做多基金整积极调仓换股,选择新标的——次新币。这是此前蔚蓝推荐ONE、LEO的原因所在,两者仍可继续关注。

看主流币EOS、XRP、BNB、XLM、ADA跌至30日线,ETH跌破20日线,TRX下探15日线。30日均线的短线支撑是有效的,看下跌程度可以看出孰强孰弱。牛市面对下跌,不应恐惧,而是贪婪,充分利用下跌观察谁是真正的强者,积极调仓换股,而不是动辄期待大幅调整。牛市有大幅调整,但既非先在,也非韭菜所能规避。夜雨剪新韭,我们能规避被左右打脸就不错了。

积极调仓换股,而非空仓以待!勇者无惧,牛市应积极做多。



比特币挖光了矿工怎么办 靠交易费稳吗?

金色财经 比特币6月4日讯 到目前为止,有超过83%的比特币将会被开采出来,预计到2040年,有超过99%的比特币会被开采出来。那么问题来了,当所有比特币都被挖出来之后,会发生什么呢? 

auURJQJIjqJsQUbJNgUmbjh0Nq5amqG6hcvoAVYb.png

比特币限量供应:2100万 

比特币的一个重要特征就是供应数量有限,仅有2100万个,这意味着它不能像美联储那样随便印钞增发。同样地,比特币有限供应使其成为了一个通货紧缩的加密货币,而且因为稀缺性也间接推动了比特币的价值上涨。 

然而,由于比特币网络是由矿工维护的,因此他们会在验证交易的时候获得区块奖励,所以也随之引发出了一系列问题,比如: 

1、当区块都被挖掘完了之后,矿工还能获得激励,他们又会从哪里赚钱呢?

2、一旦达到2100万硬上限,矿工会做些什么?

3、矿工今后会如何谋生?

4、如果比特币网络想要继续确保安全,该如何激励矿工呢?

 对于这些问题,如果回答的话其实也很简单,答案只有三个字:交易费。 

当比特币被挖光之后会发生什么? 

目前,当新区块被创建出来的时候,矿工就会收到区块奖励,其中包含了新挖掘比特币的激励和交易费用,区块奖励可以激励矿工在网络上不做违规的事情并保护网络。 

一旦所有的比特币,矿工的收入来源就只能依赖于交易费用了。但交易费能够保证矿工的正常运营吗?如果不能,矿工数量有可能大幅减少,这样一来会导致网络更加中心化,甚至导致网络最终崩溃吗?事实上,根据Interchange和加密分析师@Awe_andWonder透露,未来比特币交易费用可能会逐步增加,让矿工慢慢减少对区块奖励的依赖。

从下面的分析图表中显示,预计到2030年,比特币的交易费用会超过区块奖励,一旦交易费用占到区块奖励的一半以上,矿工就能顺利过渡到靠交易费“赚钱”。

sSpLq7JxJZ4BUrvwTaZ6gDCQyst9QcWpyRqcJpYJ.png

但是,交易费用是否足够激励矿工呢?

对于上述问题,可能没有人可以给出一个肯定的答案,因为谁都无法确定未来会如何发展,也不知道交易费用能否发挥作用。但是有足够的证据表明,矿工依靠交易费用足够维持生计,而且也能较好地维护比特币网络。

毕竟,只要比特币价格上涨,交易费用也会随之增加。不过,也有人担心交易费用上涨会阻碍更多人使用比特币,但不要忘了,相比于银行转账和购房佣金等费用,比特币交易费依然是相对较低的。正如Interchange指出:

“房产交易费是平均成交价格的2%,或是单笔8000美元。我相信未来会有更多人愿意花50美元用加密资产发送付款交易。”

比特币交易费也会随着时间的推移而增值

随着时间的推移,比特币矿工将更多的依赖交易费用,同样从长远角度来看,比特币价值也会上涨,继而导致费用增加——这意味着让矿工继续保护网络,在经济上是可行的。

当然,让矿工完全依赖交易费用不会在一夜之间发生,还有很多其他因素会导致事情发生变化。但不管怎么说,现在仍有足够的时间让矿工适应新模式,确保比特币网络安全。
