​​arround: how the blockchain will color everyday life of users

augmented reality enters the lives of millions of people. despite the massive development of technology, ar remains an undeveloped market, full of potential opportunities for advertisers. is it possible to create a single affordable market for high-quality entertainment and services built on ar technology?

arround platform developers propose to create an infrastructure where each user will be able to receive ar products (games, advertising, goods, services), and the advertiser will be able to attract interested buyers. the arround team has already developed an ar map - a 3d map, which stores detailed information on all s. for example, a virtual tour of the halls, comments to each exhibit, information on opening hours and prices for entrance tickets are available to museum visitors.

the technological basis of the platform is smart contracts that describe in detail the conditions for the use of each location. users deposit arr tokens, cryptocurrency or fiat money, register in the system and pay for goods and services.

the ecosystem consists of four components.

1. a
r social. platform for creating ar-s and publishing impressions about them. each participant can evaluate the s of augmented reality (advertising, characters), discuss them in the chat and leave feedback. the task of ar social is to introduce 3d s into the everyday life, to make technology familiar and accessible, like a navigator or online map.

2. ar adnet. decentralized platform for advertising on the ar technology. owners of shops and manufactures upload data on sales and discounts on a virtual card, the buyer sees all the information on the smartphone. retailers save millions of dollars on posters and banners as the launch of an advertising campaign takes a few minutes - just enter the data into ar adnet.

3. ar map. virtual 3d-map of trading halls, cities, and other s, containing information about goods and services, advertising banners. users scan a territory using a camera on a smartphone, data uploads to the cloud storage and link to a real location d on the gps data. the technology is similar to google maps or 2gis, information about favorite stores and brands is additionally registered. the ar map is decentralized, so the data is updated faster, each user can create a map or a virtual on it.

4. ar store. platform for sale and purchase of augmented reality s created by users. developers can use sdk with a set of templates, an open api for ding ar s in advertising materials, programs, and online maps. arround developers offer three models of implementation: free, shareware (“for donation”) and traditional, with regular payments.

the arround platform partners were the largest retailers, food manufacturers, and transport service providers. business partners include unilever, a logistics holding company scania, the largest pharmaceutical network 36.6.

the idea of the project came to the creators in 2016, the technological concept was ready in 12 months and investments were gathered to develop the mvp. the first investor of the project was the russian pharmaceutical network 36.6.

the ico of the project began on september 15, 2018, tokens (1,450 million in total) will be sold by november 15 of that year. the team plans to collect from 5 to 30 million dollars (soft and hard caps). most of the issued arrs (48.3%) will be implemented during the ico, 22% are planned to be invested in the development fund, 10% will go to the team and owners of master nodes, 8.2% are planned to be spent on bonuses, 1.5% will be required to pay bounty.

arround is an example of a large-scale ico focused on introducing augmented reality technology into a market economy.

BlackBerry Unveils Blockchain Partnership to Support Medical Research

BlackBerry Unveils Blockchain Partnership to Support Medical Research

BlackBerry, the software company and former maker of an eponymous line of mobile phones, announced Thursday its plans for a new blockchain platform aimed at storing and sharing medical data.

The firm said in a press release that it would use its "carrier-grade network operation center" (NOC) to support the digital ledger, which would be developed by biotech incubator ONEBIO. It would specifically be used to securely store data from patients, labs and monitors.

BlackBerry's NOC would be responsible for creating "an ultra-secure global ecosystem," the release claims, noting that data may be input by Internet-of-Things biometric devices as well as individuals.

The platform would also be able to anonymously share such data with researchers.

BlackBerry's first client will be the Global Commission to End the Diagnostic Odyssey for Children with a Rare Disease, an organization dedicated to helping children quickly find diagnoses for rare diseases.

The release continued:

"Co-chaired by Shire, the leading global biotech focused on rare diseases, one of the Global Commission's technology pilots will explore how BlackBerry's new solution might provide real-time, actionable analysis as the Commission seeks to use technology to shorten the time to diagnosis."

BlackBerry joins a number of other traditional smartphone developers in venturing into the crypto world.

Earlier this Nokia "wet its feet" by partnering with blockchain data platform Streamr and software company OSIsoft, in an effort to let users monetize their personal data.

The aim of the project is to allow users to "buy and sell" real-time data streams through ethereum smart contracts. They introduced a token for these transactions called the DATACoin

Another company, HTC, is going even further with its new Exodus smartphone. Set to be released by the end of the year, the Exodus is aimed at providing users the ability to store their private keys on their phone in place of separate hardware and software wallets.

UK Land Registry Begins New Phase of Blockchain Research Project

UK Land Registry Begins New Phase of Blockchain Research Project

The U.K.'s national land registry is moving into the second phase of its ongoing blockchain research effort.

The HM Land Registry announced Tuesday it was partnering with blockchain company Methods, which plans to build on R3's Corda framework to develop a platform able to store land registration information and streamline the process for buying or selling properties, according to a press release.

Dubbed Digital Street, the HM Land Registry's research began last year when it first announced the project. In addition for its desire to streamline the buy-sell process, the agency said it hoped to store more "granular information" using a blockchain platform.

In a statement Tuesday, HM Land Registry Chief Executive Graham Farrant said the agency aims to become "the world's leading land registry," citing "speed, ease of use and an open approach to data" as areas he wants to excel at.

Farrant added:

"By working with Methods on Digital Street we are taking another step toward that goal, as we explore how new technologies like blockchain can help us to develop a faster, simpler and cheaper land registration process."

R3 CEO David Rutter said the company "looks forward to working with the world's most well-recognized land registry."

Like Farrant, he noted the technology's potential to make transactions more efficient, and said R3 would be "working closely" with the Land Registry to "turn this potential into reality."

Italian Bank Consortium Trials Interbank Transfers On R3's Corda

Italian Bank Consortium Trials Interbank Transfers On R3's Corda

The second largest bank in Italy, Intesa Sanpaolo, and 13 other banks have successfully completed the first phase of an interbank reconciliation blockchain trial.

The tests, which started on June 4, were held in conjunction with ABI Lab – a research lab supported by the Italian Banking Association (ABI) – and finished last week.

The project is aimed to improve certain aspects of "spunta," or inter-bank transactions, such as the time needed to identify mismatched transactions between two banks, and the lack of a standardized process and a single communication protocol.

In the 10-month proof-of-concept and testing phase, each bank was assigned a node and the banks uploaded actual data bank data, processing 1,200,000 transactions through the course of the trial.

The interbank system is built on Corda Enterprise, the platform developed by blockchain consortium startup R3 that offers what's called a Blockchain Application Firewall. This enables the platform to be "deployed inside corporate data centres, while retaining the ability to communicate securely with other nodes anywhere else in the world," according to a press release.

Katerina Koutoulaki, associate director at R3 said:

"Currently, two banks involved in the project are members of R3. They share our goal of moving blockchain applications into commercial deployment and changing business from within and we are pleased to be working with them on this project"

The project also utilizes the Sia blockchain node infrastructure. The hope is to "create bilateral channels through which each counterparty can exchange information whilst maintaining confidentiality and privacy so that only those with a need to see the data can access it," according to the release.

ABI Lab was set up to investigate whether blockchain can provide data transparency and visibility, faster transactions and the "ability to perform checks and exchanges directly within the application."

The group is now preparing for the next phase of the project in which the banks will utilize the blockchain application for everyday transactions.

early coin executive adam white is leaving the firm

early coin executive adam white is leaving the firm

ad
am white, one of u.s.-d crypto exchange coin's most senior executives and fifth-ever employee, is leaving the company.

white, whose most recently led the institution-focused section of the firm's operations, was said to departing by coin on thursday, according to a reuters report.

according to his linkedin profile, he has held the dual roles of vice president and general manager of coin institutional for two years, having joined in 2013 as vice president, business development & product management.

as reported by coindesk, the san francisco-headquartered startup also revealed earlier this week that it has hired former instinet ceo jonathan kellner as its new managing director of the institutional coverage group.

coin representative elliott suthers reportedly said in a statement that kellner will be taking on some aspects of white's role at the firm.

coin co-founder and ceo brian armstrong said:

"over the past five years, adam helped us build our exchange business into the largest us-d crypto-trading venue and was integral to growing coin's global presence and scaling our culture to multiple offices."

the firm did not give an indication of what white's plans might be following his departure.

the news comes amid a flurry of staff additions at coin, with the exchange having also hired former charles schwab advisor chris dodds to its board of directors and former jpmorgan executive director oputa ezediaro to its institutional coverage group.

the changes all align with the company's plan to introduce more traditional finance institutions to the world of crypto assets.

as part of that push, it recently opened a new york office in order to be closer to wall street, and is planning to expand to 150 employees next year – up from 20 at the time of reporting.

according to the company, the bear market for cryptocurrencies in 2018 has not suppressed institutional demand for the novel asset class.

"when we saw the market begin to correct, which we all expected, institutions didn't lose interest," white told coindesk in mid-september. "it was exactly the opposite."

coin rolls out system to free up stuck bitcoin payments

coin rolls out system to free up stuck bitcoin payments

wi
th transaction fees "volatile and unpredictable," sending cryptocurrencies can sometimes be frustrating.

so says u.s.-d crypto exchange coin in a new blog post that sets out the issues rising from shifting miner fees, and exactly what it has been doing to address the problem.

as most who have sent or received bitcoin will know, the primary problem is that the fee variations can mean significant changes in the amount of time it takes for transactions to be confirmed. coin says this wastes company time in pointless support requests and provides users with a "frustrating experience."

the reason fees rise and fall so readily is that rather than clawing back transaction costs via a percentage – as card firms like visa and mastercard do – bitcoin and other cryptocurrencies pay miners a fee to confirm transactions. and that's d on a model not dissimilar to bidding at an auction.

at times when the bitcoin network is busiest, miners have a queue of transactions to process and these are prioritized by dealing with the transactions offering the highest fee first.

but the method can cause lengthy delays before transactions are confirmed and the funds have "arrived." it can also cause spiking fees at the busiest times, as was seen in late 2017 when the price shot up to an all-time high of around $20,000.


historic daily average transaction fees in satoshis per byte (source: coin/bitcoinfees.info)
to address the issue, coin says it has turned to a procedure which uses economic incentives built into the bitcoin protocol for improving confirmation time of transactions.

"child pays for parent" (cpfp), as it is called, has been rolled out at across the company' systems in the last few months.

cpfp works by following up a stalled bitcoin transaction (with a fee too low for the current market to want to process immediately) with a so called "child" transaction – a later transaction linked to the original "parent" transaction, and in this case, set to offer a higher fee.

since bitcoin mining clients will often batch a group of transactions, adding a better-rewarding child transaction can cause the parent to be processed sooner, the post indicates.

coin says that the process kicks in after a payment has been stuck for "at least 4 blocks" and has at times been used to automatically "rescue thousands of transactions in a single day."

the exchange adds that cpfp is carried out without the need for interaction from the customer and the results have been "really positive" so far.
