How Bitcoin's Blockchain Is Making the World More Secure - 0 views

  •  
    "But the blockchain looks set to change that. Right now, there are a number of startups that are working on tools to record ownership of a property (intellectual or physical) onto the blockchain, like Tieron, Monegraph, Colu, and Ascribe."

Will blockchain fulfil its democratic promise or will it become a tool of big tech? | J... - 0 views

  •  
    "The problem with digital technology is that, for engineers, it is both intrinsically fascinating and seductively challenging, which means that they acquire a kind of tunnel vision: they are so focused on finding solutions to the technical problems that they are blinded to the wider context. At the moment, for example, the consensus-establishing processes for verifying blockchain transactions requires intensive computation, with a correspondingly heavy carbon footprint. Reducing that poses intriguing technical challenges, but focusing on them means that the engineering community isn't thinking about the governance issues raised by the technology. There may not be any central authority in a blockchain but, as Vili Lehdonvirta pointed out years ago, there are rules for what constitutes a consensus and, therefore, a question about who exactly sets those rules. The engineers? The owners of the biggest supercomputers on the chain? Goldman Sachs? These are ultimately political questions, not technical ones."

Together we can thwart the big-tech data grab. Here's how | John Harris | Opinion | The... - 0 views

  •  
    "Blockchain technology has also opened the way to new models whereby endless micropayments can be made in return for particular online services or content; and, if people voluntarily allow elements of their data to be used, rewards can flow the other way. Here perhaps lies the key to a system beyond the current, Google-led model, in which services appear to be free but the letting-go of personal data is the actual price."

Blockchain Could Make Digital Interactions Trustworthy Again - Here's How to Understand It - 0 views

  •  
    "Once it's verified, the transaction's information, plus both your digital signature and your friend's digital signature, are stored in a block alongside many other transactions like it. Once the block is full, it gets a hash, which is a unique code that sort of acts like its nametag. It also stores its position on the chain and the hash of the previous block on the chain. (Here's an example block to illustrate what kind of information is stored there.) "

Blockchain technology, used in Bitcoin, aids U.K. vaccine program - Marketplace - 0 views

  •  
    ""Having a tamper-proof record-keeping system that can be shared across the vaccine supply chain is always important, but critically so here for the COVID vaccines," Harmon said. Hedera's chief executive believes that decentralized computer networks with hundreds or even thousands of participants can play an important role in other aspects of pandemic management - to combat vaccine counterfeiting, for example, and create unforgeable vaccination certificates."

You Don't Understand Bitcoin Because You Think Money Is Real - 0 views

  •  
    "The bitcoin blockchain was created, in part, to address this historical weakness. After the 21 millionth bitcoin is mined, in around 2140, the system will produce no more."

What are NFTs? Everything you need to know. - 0 views

  •  
    "NFTs are created on Ethereum's blockchain, which is immutable, meaning it cannot be altered. No one can undo your ownership of an NFT or re-create that exact same one. They're also "permissionless," so anyone can create, buy, or sell an NFT without asking for permission. Finally, every NFT is unique, and can be viewed by anyone. "

Germany seizes US$60 million of bitcoin - now, where's the password? - CNA - 0 views

  •  
    "Bitcoin is stored on software known as a digital wallet that is secured through encryption. A password is used as a decryption key to open the wallet and access the bitcoin. When a password is lost the user cannot open the wallet. The fraudster had been sentenced to more than two years in jail for covertly installing software on other computers to harness their power to "mine" or produce bitcoin. When he went behind bars, his bitcoin stash would have been worth a fraction of the current value. The price of bitcoin has surged over the past year, hitting a record high of US$42,000 in January. It was trading at US$37,577 on Friday, according to cryptocurrency and blockchain website Coindesk."

Centralized vs Decentralized Storage: Blockchain Changing Storage - 0 views

  •  
    "Decentralized storage platforms break apart the users' files and distribute them across multiple nodes on their network. Since the data is scattered across multiple nodes, there is no single point of failure."

As a new year dawns, expect a fresh assault on big tech | John Naughton | The Guardian - 0 views

  •  
    "This tulip-mania de nos jours has been happening with cryptocurrencies for a while, but is about to become more frenzied as the notion that blockchain - the cryptographic technology that underpins bitcoin, Ethereum et al - can become the basis for something called Web3: a new, properly decentralised version of the world wide web (as compared with the current version in which control has become effectively centralised in a small number of giant corporations)."

What is the metaverse--and what does it mean for business? | McKinsey - 0 views

  •  
    "Cathy Hackl: I think it's important to state that there is really no agreed-upon definition right now. Every morning-it's become a bit of a ritual-I go to the Merriam-Webster dictionary and type in the word metaverse. And every day it says this word is not in the dictionary. But if we needed to define it, I tend to have a pretty expansive view of what the metaverse is. I believe it's a convergence of our physical and digital lives. It's our digital lifestyles, which we've been living on phones or computers, slowly catching up to our physical lives in some way, so that full convergence. It is enabled by many different technologies, like AR [augmented reality] and VR [virtual reality], which are the ones that most people tend to think about. But they're not the only entry points. There's also blockchain, which is a big component, there's 5G, there's edge computing, and many, many other technologies. To me, the metaverse is also about our identity and digital ownership. It's about a new extension of human creativity in some ways. But it's not going to be like one day we're going to wake up and exclaim, "The metaverse is here!" It's going to be an evolution."

Decentralisation: the next big step for the world wide web | Technology | The Guardian - 1 views

  •  
    "The proponents of the so-called decentralised web - or DWeb - want a new, better web where the entire planet's population can communicate without having to rely on big companies that amass our data for profit and make it easier for governments to conduct surveillance."

Open Rights Group Scotland - E-voting's Unsolvable Problem - 0 views

  •  
    Ahhh ITGS group - a great discussion on the evoting problem would have been perfect for your Paper 2. "Remember: all of these principles of security, anonymity and verifiability have to be achieved in an understandable way. If they can't be then you get the opportunity for losers to claim fraud, and their supporters to believe them."

"THE ENVIRONMENTAL ISSUES WITH CRYPTOART WILL BE SOLVED SOON, RIGHT?" | Medium - 0 views

  •  
    "And lest you think we are dealing in long-term abstractions- this devastation has tangible, externalized cost; a recent study out of the University of New Mexico estimated that in 2018 every $1 of Bitcoin value was responsible for $0.49 in health and climate damages in the US, costs that are borne by those who will, for the most part, never see any return from cryptocurrency mining whatsoever."

The creator of Second Life has a lot to say about all these new 'metaverses' | PC Gamer - 0 views

  •  
    "The problem, he believes, is that total decentralization inevitably increases wealth inequality. He pointed me to a simulation he designed last year in which bouncing balls demonstrate the theory that "the rich actually always get richer, no matter what." "
