"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." "

"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."

"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."

""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."

"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.) "

"Facebook could also shift monetization from ads to ecommerce via blockchain-based payments and services"

"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."

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 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."

"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."
