Crypto exchange Coinbase says Apple has shut down the ability for users to send NFTs because it can’t collect the 30% in-app fee

Posted by in category: blockchains

Apple’s mobile store can typically charge up to 30% commission on in-app purchases, but gas fees don’t occur within the app. Gas fees, which are the charge a user pays to perform a function on a blockchain, keep its network running. Therefore, you can’t pay for gas fees using Apple’s software.

Apple did not immediately respond to Insider’s request for comment.

“For anyone who understands how NFTs and blockchains work, this is clearly not possible,” Coinbase said. “Apple’s proprietary In-App Purchase system does not support crypto, so we couldn’t comply even if we tried.”

In the metaverse and NFT 2.0, marketers should focus on utility and community

Posted by in categories: blockchains, innovation

Check out the on-demand sessions from the Low-Code/No-Code Summit to learn how to successfully innovate and achieve efficiency by upskilling and scaling citizen developers. Watch now.

As we move into the NFT 2.0 technology space, we see a more innovative and accessible approach to creating a user-centric experience where participants can benefit from utility. Web3 marketers are also delving into how brands can position themselves to continue generating profit from NFT ventures while adding value to their products. However, for NFTs to thrive in the Web3 ecosystem, consumers need storytelling and value proposition, especially in an environment where technology is constantly evolving.

Web3 marketing agencies have been carefully implementing brands into the metaverse to build awareness and actual utility for consumers they engage with. However, for a brand to be true to its fan base, its digital assets must incorporate audience and community engagement to create a worthwhile experience and keep consumers coming back.

What can blockchain do for increasing human longevity?

Posted by in categories: blockchains, finance, life extension

Longevity is not yet considered an official medical term, and aging is not officially considered a disease but a natural occurrence in every living thing.

However, some biologists, researchers and practicing doctors believe this approach should change, and they are striving to discover the mechanisms of aging in humans. In doing so, they are creating age clocks by defining biomarkers for measuring biological age, exploring the best lifestyle habits and natural supplements, and inventing new drugs that could stop us from getting older.

Longevity has been on the radar of crypto leaders for some time already, which is not a surprise given that the industry promises to improve humankind through innovation. Indeed, one prominent event in the longevity industry, the Longevity Investors Conference, is organized by Marc P. Bernegger and Tobias Reichmuth, who were previously involved with the Crypto Finance Group.

Twitter Reveals ‘NFT Tweet Tiles’ in Order to ’Impact‘ the Social Media Experience

Posted by in categories: blockchains, business, Elon Musk

Is Twitter getting into the NFT business?

According to the social media company Twitter, the firm plans to launch a new feature called “NFT Tweet Tiles,” a segregated panel within a tweet that showcases non-fungible tokens (NFTs) and the marketplaces that list the specific NFT shared. The new NFT concept is expected to drop soon, in order to “impact the Tweet experience,” Twitter developers explained on Oct. 27.

Research team proposes unclonable, invisible machine vision markers using cholesteric spherical reflectors

Posted by in categories: augmented reality, blockchains, economics, mobile phones, physics, robotics/AI, wearables

Over the last three decades, the digital world that we access through smartphones and computers has grown so rich and detailed that much of our physical world has a corresponding life in this digital reality. Today, the physical and digital realities are on a steady course to merging, as robots, Augmented Reality (AR) and wearable digital devices enter our physical world, and physical items get their digital twin computer representations in the digital world.

These digital twins can be uniquely identified and protected from manipulation thanks to crypto technologies like blockchains. The trust that these technologies provide is extremely powerful, helping to fight counterfeiting, increase supply chain transparency, and enable the circular economy. However, a weak point is that there is no versatile and generally applicable identifier of physical items that is as trustworthy as a blockchain. This breaks the connection between the physical and digital twins and therefore limits the potential of technical solutions.

In a new paper published in Light: Science & Applications, an interdisciplinary team of scientists led by Professors Jan Lagerwall (physics) and Holger Voos (robotics) from the University of Luxembourg, Luxembourg, and Prof. Mathew Schwartz (architecture, construction of the built environment) from the New Jersey Institute of Technology, U.S., propose an innovative solution to this problem where physical items are given unique and unclonable fingerprints realized using cholesteric spherical reflectors, or CSRs for short.

RIMOWA luggage jumps into the metaverse phygital market with RTFKT NFT collab

Posted by in category: blockchains

After a short period of relative silence, the metaverse became a hot topic again in no small part thanks to Mark Zuckerberg’s and Meta’s most recent buzz, which, unsurprisingly, split people into camps again. Some say or are hoping that the metaverse is already dead and, along with it, the more controversial NFTs. If that were the case, it seems that nobody told luxury luggage maker RIMOWA about it because it seems that the marque will be diving right into this mess when others seem to be silently stepping out. RIMOWA has partnered with Nike-owned digital fashion brand RTFKT to bring its iconic luggage brand to the metaverse via two NFT drops, but RIMOWA fans can rest assured that they can still get this upcoming limited edition luggage in physical form as well.

The Obligatory Mind Uploading Blockchain Crossover

Posted by in categories: biotech/medical, bitcoin, blockchains, computing, cryptocurrencies, neuroscience

A classic thought experiment in the philosophy of mind is reduplication, in which a person (or her mind) is duplicated such that two or more descendant people of shared mental ancestry now exist where previously there was one. The philosophical quandary is to resolve what happened to the original person’s identity. Did she survive and if so, in which of the resulting people’s minds? Which of the two resulting people is the original and which is a mere copy of denigrated identity status? Alternatively, is there something fundamentally wrong with the wording of such questions, such that we should we adopt a different perspective on the nature of personal identity that offers alternative solutions to the reduplication quandary? Reduplication further arises not only in abstract philosophical musings, but also in the futuristic and variously conceivable (depending on the reader’s tastes), technology of mind uploading, in which a person’s physical brain is emulated via the technology of whole brain emulation. While mind uploading might produce a single result, such as if the original brain is destroyed by the uploading process and only one upload is created, we can also conceive of either nondestructive scenarios (in which the original brain is not destroyed) or scenarios that produce multiple uploads. Either case results in multiple descendant minds, each operating in distinct physical systems (brains or cloned brains, or computers of some sort). The philosophy of personal identity has produced several possible stances on the nature of personal identity. The most popular are body identity and psychological identity, with other options including closest continuer identity, space-time worm identity and branching identity. However, there is always room for new theories to enter the discussion. The way in which blockchains work, and Bitcoin’s mining process and protocol for handling orphaned blocks, suggests a new theory of identity along with a new solution to the reduplication problem. The proposed blockchain solution to personal identity has applications to the handling of the reduplication problem as it may arise during a futuristic mind uploading procedure.

A blockchain holds a hashed transaction ledger, essentially the history of all transactions encoded to prevent any subsequent alteration of the history. In this way, all transactions back to the beginning of the ledger’s history can be confirmed by any interested party. Deceit, fraud, and other attempts to undermine the history simply don’t work, and consequently blockchains enable a variety of interactions with the currently most popular being digital currency. In addition to more conventional applications, blockchains could also be used to assign identity status (original or copy) to the descendent minds of a mind uploading procedure. Each descendant could then venture out into the world confident that their identity status will be honored by all third parties thereafter. Let us call this the blockchain theory of personal identity.

$1.2 Billion Metaverse Horrified

Posted by in categories: blockchains, cryptocurrencies

Metaverse project Decentraland, a sandbox environment that allows users to buy and sell virtual real estate, isn’t exactly teeming with people. Despite billions of dollars in valuations, companies betting on a metaverse future simply haven’t made much headway.

In fact, according to data aggregator DappRadar, the Ethereum-based world Decentraland only had 38 “active users” over a period of 24 hours — a confoundingly low number, especially considering the company has a market cap of a whopping $1.2 billion.

Decentraland pushed back, though, saying that “active users” are defined as unique blockchain wallet addresses that interact with its system. As CoinDesk explains, that means users who simply log in to chat or interact with others aren’t being counted.
