Kirobo Launches a “P2P Swap Button” Smart Contract-Powered Tool


Kirobo–a blockchain technology company that aims to be the enabler of DeFi, granting people control over their cryptocurrencies–has launched a smart contracts-powered ‘P2P Swap Button’, per a press release on July 27.

The P2P Swap Button

The button allows for direct peer-to-peer swapping of tokens without the need for a middleman. Typically, the intermediary is an exchange or an external asset custodian.

Furthermore, Kirobo has said that the P2P Swap Button allows users to set their preferred token prices avoiding slippage. Usually, cryptocurrency exchanges adjust token prices depending on several factors, like existing liquidity and traders’ order sizes. Large order sizes in an exchange with thin liquidity leads to high slippage, unfavorable to the trader.

The P2P Swap Button provides a means of linking parties in a decentralized manner. Using the tool, transactors will swap tokens at better rates, without having to exchange at a discount. Traders also have the liberty to choose when to trade for the best prices and swap with relatively low gas fees.

Disrupting the Token Swapping Market

Besides eliminating price risks, security is enhanced since all swaps are non-custodial. Funds won’t leave the custody of either party until there is confirmation and approval of the transfer effected using a verifying password.

Asaf Naim, the co-founder and CEO of Kirobo, said the tool could disrupt the token swapping market.

“Our P2P Swap Button is exactly the tool needed to disrupt the token swap market. Until now, people had to use an exchange if they wanted to swap, but they’ll never get the best deal there because venues adjust prices according to how much you’re selling. We’re allowing people to trade directly with their peers for pre-agreed prices and complete safety,” he said.

To level the field, the CTO of Kirobo, Tal Asa, said the tool would also be freely available to its users. This way, Asa explains, traders will make more lucrative swaps with confidence that the operation is completely secure.

The P2P Swap Button secures transactions using an authentication key whose component parts are split three ways – between the smart contract, the transaction initiator, and the Kirobo server. By employing a multi-signature, multi-transaction mechanism, Kirobo, as per the press release, removes the risk of fraud and errors.

A Tool to Eliminate Human Error in Immutable Crypto Transfers

Kirobo has also launched an ‘Undo Button’, allowing users to reverse Ethereum, UNI, LINK, SUSHI, USDT, and KIRO transactions sent in error. The tool obligates the sender to create a passcode which is then sent to the recipient. If the funds fail to reach the recipient, the transaction can be canceled and reversed using the passcode.

The tool shields users against human errors, which have resulted in millions of dollars of lost funds. Unlike in legacy finance systems, cryptocurrency transactions are immutable. All transactions sent to the wrong address are permanently lost because a blockchain cannot be rolled back.

A New York Times report indicates that over 20 percent of all Bitcoin in circulation are inaccessible, trapped behind complex encryptions, and declared lost due to forgotten passwords.

Undo Button Has Retrieved over $6 Million of Crypto Assets

Kirobon has been audited by several blockchain security firms and the Israel Innovation Authority. The agency also extended Kirobo two grants, helping the firm launch its solutions.

With the increasing popularity of cryptocurrencies and DeFi, the Undo Button has processed $1.5 billion of cryptocurrencies, retrieving over $6 million of transfers through canceled transactions.

Amazon expands same-day Prime delivery to 6 more U.S. cities – otcbbstocknews.com


Amazon announced this morning it’s expanding its faster, same-day delivery service to half a dozen more U.S. cities. The service, which the retailer has been working to make same-day delivery even faster over the past year, now offers consumers in a number of markets the ability to shop up to 3 million items on Amazon.com, then receive their orders in only a few hours.

To do so, Amazon invested in what it called “mini-fulfillment centers” closer to where customers lived in select U.S. markets, initially in Philadelphia, Phoenix, Orlando, and Dallas. Those customers could then shop across a dozen merchandise categories, including Baby, Beauty & Health, Kitchen & Dining, Electronics, Pet Supplies, and more. As the pandemic continued to impact Amazon’s business, in November 2020, Amazon expanded its faster same-day service to more cities, to include Nashville and Washington, D.C.

With today’s expansion, Amazon is rolling out same-day delivery to Prime members in Baltimore, Chicago, Detroit, Tampa, Charlotte, and Houston, bringing the total markets served to 12. In these markets, shoppers will be able to place orders online throughout the day then have items on their doorstep in as fast as 5 hours, Amazon says. Customers can also place orders by midnight to have their orders arrive the following morning.

The service continues to be free with no additional charges on orders over $35 that qualify for same-day delivery. Orders under $35 have a $2.99 fee for Prime customers, and a $12.99 fee for non-members. Prime membership, meanwhile, is $12.99 per month or $119 per year.

The time frame commitments for same-day delivery are the same as those Amazon promised last year when it first announced its plans to speed up Prime delivery. Orders placed between midnight and 8 AM will arrive today by 1 PM. Orders placed between 8 AM and 1 PM arrive by 6 PM; those placed between 1 PM and 5 PM will arrive by 10 PM; and those placed between 5 PM and midnight will arrive overnight by 8 AM. That means customers can place orders fairly late and receive their items before they head out of the house the next day.

Faster same-day delivery has been one of the most significant services Amazon has used to challenge rivals like Walmart and Target, who both benefit from having a large brick-and-mortar footprint that allows them to more quickly serve their customers through same-day order pickup, curbside pickup, and same-day delivery services. While Walmart partners with third-parties on its same-day service, Express delivery, largely focused on grocery, Target acquired delivery service Shipt in 2017 to bring its fast delivery services in-house.

In response to the growing competition, Amazon has been recently acquiring smaller warehouse space inside major urban metros, including in these six new markets where it’s now announcing same-day delivery, as well as larger markets, like New York, and even suburban neighborhoods. It also acquired Whole Foods for $137.7 billion in 2017, not only to more fully participate in the online grocery business, but also in part because of its large retail footprint.

As Amazon has sped up the pace of what’s available under “Prime” delivery, it has wound down its older “Prime Now” business, which was retired Aug. 30 and will be fully shut down by year-end. The separate app had allowed customers to shop items that were available in one or two hours for an additional fee.

The news follows Amazon’s earning miss last week, when the retailer fell short of Wall St.’s estimates for revenue, and gave a weaker than-expected outlook for the quarter ahead, which Amazon attributed to difficult comparisons with a time frame that included Covid lockdowns during height of the pandemic in 2020. The company reported $113.08 billion in revenue and earnings of $15.12, versus expectations of $115.2 billion and $12.30.

Patients who miss multiple GP appointments stay missing from healthcare

Research into the healthcare journey shows that patients who miss appointments with their GP are also less likely to attend hospital outpatient appointments.  

 Patients who missed more than two GP appointments (on average) per year, were at least three times more likely to miss outpatient appointments compared to those who missed no GP appointments.  

“Missingness” from outpatient mental health services was especially high and it was also associated with “irregular discharge” from in-patient care.  

 However, the researchers were surprised to find that patients who miss GP appointments do not use Emergency Departments instead. 

“There’s often a belief that people who miss GP appointments must be clogging up A&E departments, but that’s not what this research shows,” said Dr. David Ellis from the University of Bath’s School of Management.  

“Missing multiple health care appointments may be linked to other factors including frailty, neurodevelopmental problems such as attention-deficit/hyperactivity disorder, neurodegenerative disease or psychological trauma. These factors individually or in combination may impact a person’s ability to organize, attend, or follow through on offers of care and require further research.”

 The study, carried out by the Universities of Bath, Glasgow and Aberdeen examined over half a million patients’ appointment histories in Scotland over a three-year period from September 2013 to September 2016. 

 A previous research paper from the same team demonstrated links between missed GP appointments and early death, and received a Research Paper of the Year award from the Royal College of General Practitioners. 

“This research pre-dates COVID times—however it’s a very pertinent reminder that as we attempt to reconfigure acute services there is not a level playing field in terms of engaging patients in that recovery,” said Dr. Andrea Williamson, the study’s principal investigator from the University of Glasgow. 

“Because patients have a much higher risk of early death, identifying patients at higher risk of missingness and taking steps to ensure patients attend should be part of the recovery strategy.

“Missingness in health care often focuses on what it means for a service, particularly in terms of financial expense, however our work suggests that missed appointments have serious impacts for patients. 

“Policymakers, health service planners and clinicians should consider the role and contribution of ‘missingness’ in health care to improving patient safety and care.” 

“‘Missingness’ in health care: Associations between hospital utilization and missed appointments in general practice. A retrospective cohort study” is published in PLOS ONE.

Google’s New Cryptocurrency Ad Policy Goes Into Effect – Featured Bitcoin News


Internet giant Google’s new ad policy has gone into effect. The company now allows certain cryptocurrency ads, such as those promoting cryptocurrency exchanges and wallets. Advertisers must meet certain requirements and be certified by Google.

Google Now Allows Some Crypto Ads

Google’s new ad policy for financial products and services, announced in June, has gone into effect. A notice on the internet giant’s website details:

Beginning August 3, advertisers offering cryptocurrency exchanges and wallets targeting the United States may advertise those products and services when they meet the following requirements and are certified by Google.

To be certified by Google, advertisers must either be registered with the Financial Crimes Enforcement Network (FinCEN) as a money services business or be a federal or state-chartered bank. They must also comply with relevant legal requirements and their ads and landing pages must comply with Google’s advertising policies.

In 2018, Google banned ads relating to “Cryptocurrencies and related content (including but not limited to initial coin offerings [ICOs], cryptocurrency exchanges, cryptocurrency wallets, and cryptocurrency trading advice)” as well as ads for crypto-related “aggregators and affiliates.” Google subsequently allowed select crypto ads in the U.S. and Japan.

In June last year, a class-action lawsuit was filed against Google, Facebook, and Twitter for banning cryptocurrency ads by Sydney-based law firm JPB Liberty.

While the new policy allows certain crypto ads, Google still does not allow ads for ICOs, defi trading protocols, and those “promoting the purchase, sale, or trade of cryptocurrencies or related products.” Moreover, “Ad destinations that aggregate or compare issuers of cryptocurrencies or related products” are prohibited.

One of the prohibited ad categories is “celebrity cryptocurrency endorsements.” Many scams have taken advantage of Google and Youtube to promote fraudulent bitcoin giveaways. Apple co-founder Steve Wozniak sued Google and Youtube in July last year for promoting bitcoin giveaway scams using his name and likeness. However, the court ruled in Google’s favor.

What do you think about Google changing its policy to allow cryptocurrency ads? Let us know in the comments section below.
