Lately, the controversial topic of censorship on Big Tech platforms reached a turning point when U.S. President Donald Trump’s campaign account was banned on both Twitter and Facebook for “spreading coronavirus misinformation.”
The conversation over who has control over what kinds of information that get out to what kinds of audiences is not new. As we move toward Web 3.0, many believe this future version of the internet will be a more decentralized, immutable and censorship-resistant version of the web.
The decentralized data storage solution InterPlanetary File System, or IPFS, is a peer-to-peer hypermedia protocol that is designed to make the web “faster, safer and more open.” It allows users to download webpages and content that is stored across multiple nodes instead of from a central server. With the current paradigm, if anything is changed or blocked, there is no reliable way to access it again. IPFS aims to address deficiencies like this and more.

Security, privacy, scalability and efficiency limitations of Web 2.0
As mentioned, because data is currently stored in centralized servers, they can be accessed, altered or removed by any party that has control of the server. In terms of security and privacy, this is problematic, as control of the server equals control of the data. This could be a legitimate party, but it could also be a hacker or a political authority.
When Turkey decided to ban Wikipedia, IPFS technology was utilized to host a mirror version of Wikipedia so that the site could still be accessed. The Catalan Pirate Party has used it to bypass a block ordered by the High Court of Justice of Catalonia on websites related to the Catalan independence referendum. A Chinese news source, Matters.news, has also utilized IPFS to publish articles to bypass censorship.
The current internet protocol relies on location-based addressing, which identifies data by its location rather than its content. Even if the same data is available at a nearer location, it will still trek all the way to a specific location/address to access that data, which is a limitation in terms of efficiency.
This has served us satisfactorily so far but only because the size of the average web page was relatively small — average web page size increased from only 2 KB to 2 MB the first two decades of the internet. Now, with big data and on-demand HD video streaming, people have started consuming and producing more and more data. The capacity to scale is more important than ever.
Distributed hash tables enable efficient content access and lookup
Using Kademlia distributed hash tables, or DHT, the IPFS P2P file-sharing system spreads data across a network of computers that are coordinated to enable efficient access and lookup between nodes. This kind of data structure is decentralized and functions reliably even when nodes fail or leave the network (fault-tolerant).
Instead of location-based addressing, IPFS addresses a file based on content identification. The content identifier is a cryptographic hash of the content at that address, a unique hash that allows verification of the content asked for.
DHT provides a decentralized data structure where IPFS peers can locate other peers and the content requested. Its fault-tolerant feature means that peers can function independently without central coordination, enabling the system to scale and accommodate millions of peers — not to mention its ability to resist content censorship due to its decentralized structure.
Decentralized marketplace to incentivize data storage and retrieval
Now that we know how IPFS technology uses DHT to locate peers and content, we can move on to how content is requested and retrieved. Blocks of data are exchanged over the IPFS network through its data trading module called Bitswap. As a message-based protocol, Bitswap’s primary roles are to acquire data blocks requested by the client peer/s and send them accordingly to the respective peer/s.
While these tasks are straightforward, the complexity arises from the actual exchange between peers, where “strategies” are required to decide when and to whom to send blocks of data. Unlike BitTorrent, where blocks being exchanged come from a single torrent (usually a single file), on IPFS, it is a big swarm where peers can pull blocks from just about any peer who has them.
Modeling the block exchange as a data exchange marketplace, each peer participant has an internal strategy used to decide if content will be exchanged with any other participant. Strategies could include incentivization, bartering, rewarding uptime, punishing downtime or other approaches.
The developers of IPFS have rolled out an incentivized, bartering, uptime-rewarding and downtime-penalizing block exchange protocol called Filecoin.
The idea is to allow anyone with unused hard-drive storage space to participate as a storage provider in a decentralized marketplace whereby prices are set based on supply and demand. This is a departure from centralized cloud storage with fixed pricing, such as Amazon Web Services, Microsoft and Google.
The network is market-driven and designed to add economic stimulus in order to incentivize participation, strong end-to-end encryption, cryptographic deletion and more. Miners do not only compete on cost; other factors come into play, such as reputation, reliability, data availability, etc. to ensure that the network operates fairly and continues to improve.
The block exchange protocol relies on proof-of-replication, which is used to prove that data is safely stored somewhere and is accessible; and proof-of-space-time is used to prove that data was stored throughout a period of time.
A more resilient, efficient, censorship-resistant and robust internet
These protocols all work together to allow IPFS to form an extensive P2P system for distributing, storing and retrieving blocks of data quickly and robustly.
Resilience, efficiency, censorship-resistance and robustness will be the markers of this future model of the internet.
Its decentralized, fault-tolerant features will drive its capacity to scale and hopefully enable the inclusion of millions of users to participate in its global information network system.

Bringing carbon emissions reporting into the new age via blockchain
Published
3 Stunden agoon
Dezember 29, 2020By
Blockchain for supply chain management is one of the most practical business applications for large, multi-party sectors seeking trust and transparency across daily operations. As such, the mining and metals sector has now started to leverage blockchain technology to effectively track carbon emissions across complex, global supply chains.
This month, the World Economic Forum launched a proof-of-concept to trace carbon emissions across the supply chains of seven mining and metals firms. Known as the Mining and Metals Blockchain Initiative, or MMBI, this is a collaboration between the WEF and industry companies including Anglo American, Antofagasta Minerals, Eurasian Resources Group, Glencore, Klöckner & Co., Minsur, and Tata Steel.
Jörgen Sandström, head of the WEF’s Mining and Metals Industry, told Cointelegraph that the distributed nature of blockchain technology makes it the perfect solution for companies within the sector looking to trace carbon emissions:
“Forward-thinking organizations in the mining and metals space are starting to understand the disruptive potential of blockchain to solve pain points, while also recognizing that the industry-wide collaboration around blockchain is necessary.”
According to Sandström, many blockchain projects intended to support responsible sourcing have been bilateral, resulting in a fractured system. However, this new initiative from the WEF is driven entirely by the mining and metals industry and aims to demonstrate blockchain’s full potential to track carbon emissions across the entire value chain.
While vast, the current proof-of-concept is focused on tracing carbon emissions in the copper value chain, Sandström shared. He also explained that a private blockchain network powered by Dutch blockchain development company Kryha is being leveraged to track greenhouse gas emissions from the mine to the smelter and all the way to the original equipment manufacturer. Sandström mentioned that the platform’s vision is to create a carbon emissions blueprint for all essential metals, demonstrating mine-to-market-and-back via recycling.
To put things in perspective, according to a recent report from McKinsey & Company, mining is currently responsible for 4% to 7% of greenhouse gas emissions globally. The document states that Scope 1 and Scope 2 CO2 emissions from the sector (those incurred through mining operations and power consumption) amount to 1%, while fugitive-methane emissions from coal mining are estimated at 3% to 6%. Additionally, 28% of global emissions is considered Scope 3, or indirect emissions, including the combustion of coal.
Unfortunately, the mining industry has been slow to meet emission-reduction goals. The document notes that current targets published by mining companies range from 0% to 30% by 2030 — well below the goals laid out in the Paris Agreement. Moreover, the COVID-19 crisis has exacerbated the sector’s unwillingness to change. A blog post from Big Four firm Ernest & Young shows that decarbonization and a green agenda will be one of the biggest business opportunities for mining and metals companies in 2021, as these have become prominent issues in the wake of the pandemic. Sandström added:
“The industry needs to respond to the increasing demands of minerals and materials while responding to increasing demands by consumers, shareholders and regulators for a higher degree of sustainability and traceability of the products.”
Why blockchain?
While it’s clear that the mining and metals industry needs to reduce carbon emissions to meet sustainability standards and other goals, blockchain is arguably a solution that can deliver just that in comparison to other technologies.
This concept was outlined in detail in an NS Energy op-ed written by Joan Collell, a business strategy leader and the chief commercial officer at FlexiDAO, an energy technology software provider. He explained that Scope 1, 2 and 3 emission supply chains must all be measured accurately, requiring a high level of integration and coordination between multiple supply chain networks. He added:
“Different entities have to share the necessary data for the sustainability certification of products and to guarantee their traceability. This is an essential step, since everything that can be quantified is no longer a risk, but it becomes a management problem.”
According to Collel, data sharing has two main purposes: to provide transparency and traceability. Meanwhile, the main feature of a blockchain network is to provide transparency and traceability across multiple participants. On this, Collel noted: “The distributed ledger of blockchain can register in real time the consumption data of different entities across different locations and calculate the carbon intensity of that consumption.”
Collel also noted that a digital certificate outlining the amount of energy transferred can then be produced, showing exactly where and when emissions were produced. Ultimately, blockchain can provide trust, traceability and auditability across mining and metals supply chains, thus helping reduce carbon emissions.
Data challenges may hamper productivity
While blockchain may appear as the ideal solution for tracing carbon emissions across mining and metals supply chains, data challenges must be taken into consideration.
Sal Ternullo, co-lead for U.S. Cryptoasset Services at KPMG, told Cointelegraph that capturing data cryptographically across the entire value chain will indeed transform the ability to accurately measure the carbon intensity of different metals. “It’s all about the accuracy of source, the resulting data and the intrinsic value that can be verified end to end,” he said. However, Ternullo pointed out that data capture and validation are the hardest parts of this equation:
“Where, when, how (source-cadence-process) are issues that organizations are still grappling with. There are a number of blockchain protocols and solutions that can be configured to meet this use case but the challenge of data capture and validation is often not considered to the extent that it should be.”
According to Ternullo, the sector’s lack of clear standards on how emissions should be tracked further compounds these challenges. He mentioned that while some organizations have doubled down on the Sustainability Accounting Standards Board’s capture and reporting standard, there are several other standards that must be evaluated before an organization can proceed with automation, technology and analytical components that would make these processes transparent to both shareholders and consumers.
To his point, Sandström mentioned that the current proof-of-concept focused on tracing carbon emissions in the copper value chain demonstrates that participants can collaborate and test practical solutions to sustainability issues that cannot be resolved by individual companies. At the same time, Sandström stated that the WEF is sensitive to how data is treated and shared: “Having an industry approach enables us to focus on practical and finding viable ways to deliver on our vision.”
An industry approach is also helpful, with Ternullo explaining that an organization’s operating models for culture and technology must be aligned to ensure success. This is the case with all enterprise blockchain projects that require data sharing and new ways of collaboration, which may very well be easier to overcome when performed from an industry perspective.

The new ‘Bank of England’ is ‘no bank at all’
Published
4 Stunden agoon
Dezember 29, 2020By
As one of the first countries to industrialize in the 1760s, Britain’s manufacturing revolution instigated one of the greatest practical and ubiquitous changes in human history. But even more extraordinary than the cultural shift itself, is the fact that Britain’s industrialization remained way ahead of potential competition for decades. Only in the early 1900s did historians come to grips with the issues of causation. Max Weber’s pithy answer, “the Protestant work ethic,” pointed to Puritan seriousness, diligence, fiscal prudence and hard work. Others point to the establishment of the Bank of England in 1694 as a foundation for financial stability.
In contrast, continental Europe lurched from one national debt crisis to another, then threw itself headlong into the Napoleonic wars. Unsurprisingly, it was not until after 1815 that industrialization took place on the European mainland, where it was spearheaded by the new country of Belgium.
250 years later, another revolution has begun with the launch of Bitcoin (BTC), but this one is more commercial in nature than industrial. Though the full impact has yet to play out, the parallels between these two historical events are already striking.
Bitcoin may not match the obviousness of industrialization, but the underlying pragmatics touch on the very foundations of the non-barter economy. Like the establishment of the Bank of England, the creation of the cryptocurrency infrastructure has been prompted by ongoing and worsening threats to financial stability: systemic fault-lines created by macroeconomic challenges stemming from the 2008 financial crisis.
If you can’t beat ‘em, join ‘em…right?
Where a central bank once anchored financial enlightenment, it now plays the role of antagonist. For those who could “connect the dots” in 2008, there was the realization that central banks no longer existed as guardians and protectors of national currencies, but rather as tools for creating politicized market distortions, abandoning their duty to preserve wealth in favor of creating the conditions for limitless, cheap government debt. While many of the underlying intentions were benign, the process inherently worked to punish savers and reward reckless debt.
Meanwhile, it has steadily taken time for the potential of digital assets to reach their potential and approach something like critical mass, though thankfully full acceptance shouldn’t take as long as Britain’s industrial revolution. Over the past 12 years, cryptocurrencies have moved from unknown to novel to significant, growing interest. As a result, profound changes are underway, affecting the mechanics by which investors, the investment industry, wealth managers and even the commercial banking sector are engaging with cryptocurrencies.
This interest has accelerated as we enter into a period of deep economic uncertainty and growing awareness that structural soundness is shifting away from traditional investment options. Not only that, this growing financial innovation and public interest has largely occurred outside of the central banks’ control, if not outright antagonism led by the banks’ regulatory arms in government.
Now, many central banks are trying to join a game they’ve tried almost every way of beating, with digital currencies that adopt the glowing sheen of crypto innovation, but which also eschew the underlying innovations and philosophy that made those innovations so popular to begin with.
Follow or get out of the way
The popularity of cryptocurrency has largely been due to its protean fungibility — it has been whatever the independent financial community has needed it to be, from digital currency to speculative financial instruments to smart contracts that can power smart financial technology.
However hard central banks might try to co-opt the hype of cryptocurrency, cryptocurrency succeeding will mark the fundamental end of critical aspects of the central banking monopoly by offering a more competitive vehicle for facilitating commercial transactions and providing a more stable medium to store monetized assets. Cryptocurrencies actually offer real returns on “cash” deposits, something that the fiat banking system has long since abandoned. Most of all, cryptocurrencies reveal the fictitious nature of fiat currencies as a principle.
Cryptocurrencies as an ecosystem will increasingly constrain, redirect and set the parameters for government macroeconomic policies. Certainly, sound alternatives to fiat currencies will drive the latter to the periphery of commercial life, concomitantly reducing the number of tools the nation-state has at its disposal to regulate or respond to changing economic conditions. Above all, this means that government financial engagement can no longer be a rule unto itself. It will have to engage by the same principles as everyone else. A level playing field here has dramatic implications.
Against the backdrop of the essential limits of fiat currencies, current geo- and macroeconomic policies and a new emerging world order, cryptocurrencies offer vast potential as an efficiency facilitating frictionless commerce and investment, a medium of stability against uncertainty and inflation, increased security in value transfer and wealth management, optimum autonomy in an increasingly intrusive climate, and “cash” asset preservation/growth in a world of negative interest rates.
The edifice that supports the concept of a “global reserve currency” is also weakening. This will reduce political influence over global finance, as well as nations’ abilities to run a long-term balance of payments deficits, current account deficits and borrow at little or no interest. Indeed, given current trends, changes in trading mechanics may speedily evolve to the point that such “reserve currencies” no longer have a function at all. And cryptocurrency success will hasten the end of the U.S. dollar monopoly in global commerce.

Why you wouldn’t eat chicken nuggets, and why you shouldn’t trust Big Data
Published

Just like you might think twice about eating chicken nuggets once you see how they are made, you’d likely hesitate about volunteering your personal information once you see how it is used and monetized.
Freedom has become one of the world’s most commoditized assets — and over the years, the internet has eroded it.
We live in a world where we’re confronted with 5,000 words of terms and conditions when buying sneakers. Crucial details about what companies do with our data is buried in masses of legalese — prompting most of us to click “I agree” without thinking of the consequences.
In other cases, companies are unacceptably opaque about how our data is used. This is a big problem when businesses are offering their services for “free”… provided we can give our email address, phone number and a few other details.
A scene from the recent sci-fi series Maniac perfectly illustrated where the world is heading. A character is given a choice — they can either pay for their subway ticket or get it for free in exchange for some personal information. As you’d guess, they bluntly chose the latter.
That’s basically what we’re doing every day — giving our data to corporations, big and small, and sacrificing our privacy and freedom in the process.
It’s gotten so bad that individual states have had to step in with rules and regulations designed to protect the public, many of whom are unaware of what they’re signing up for when they tick a seemingly innocuous box on a website.
And it’s also telling that tech giants are worried about the taps being turned off. When Apple unveiled a new feature that would enable users to opt out of having their activity tracked across apps and websites, Facebook launched a ferocious PR campaign against the measures. The social network said it was speaking out to protect the small businesses who rely on its platform for targeted advertising. Cynics among you will see it as a brazen attempt to protect profits by a company charged with some of the most insidious and influential data mining in history.
Pandora’s box has been opened
The tide is beginning to change — because we’ve opened Pandora’s box — and the world is starting to have long-overdue discussions about the privacy we’re entitled to online.
For more than 10 years now, we’ve experienced abundant financial freedom thanks to Bitcoin (BTC) and its rivals… but there’s still a long way to go in other parts of our society.
Last week, I went to the shop and spontaneously bought some moisturizer, and when I got home, I did a Google search to learn more about the product. For the next seven days, I was bombarded with moisturizer ads on Facebook.
Just like our health, our well-being and our careers, freedom is an inner personal responsibility that we need to monitor, maintain and protect — especially in the digital realm, where it can all too easily be sold in exchange for access to free services.
To feel free and safe in our homes, we rely on the privacy of our ownership, and the trustworthiness of our friends and neighbors. Government laws and housing association rules underwrite this. But we also entrust our financial privacy to institutions — in the expectation that they will be held accountable by regulators and central banks — and the whole reason Bitcoin launched in 2009 was because our expectations weren’t being met.
Why blockchain is the answer
Every modern proof-of-stake blockchain tackles the problems surrounding digital privacy and trust in a unique way, and in these vibrant communities, decentralized governance helps to ensure that standards are upheld, with slashing mechanisms serving as a deterrent to those who are tempted to work against a network’s best interests.
With PoS blockchains, users benefit from informed consent. They’re kept in the loop about proposals for improving and expanding the network and ideas for new services. Digital social consensus means they can read debates about the pros and cons associated with each proposal, come to their own conclusions, and cast a vote accordingly. Can you honestly imagine a tech giant doing this?
Privacy issues can be solved by generating abstract network addresses that are not permanently tied to public keys — or through the use of special proxy smart contracts, which are similar to VPN and Tor but on top of the blockchain.
Can blockchain technology solve some of the most pressing privacy and trust issues seen in a generation? I believe so. Once the technology is there and transactions are cheap enough, consumers will be able to make a choice — share their private data or pay a small fee instead.
We need to learn harsh lessons from the past and make the right decision this time around. I remember the early days of email when spam messages were a big issue. A small sender’s fee was considered as a way of circumventing this problem — but in the end, the likes of Gmail came out on top. Now, there’s no monetary cost… we just pay the small price of Google hosting all of our electronic correspondence.
Proof-of-stake blockchains can deliver cheap transactions, decentralized governance that regulates the network’s rules, maximum privacy, and no data collection policies. Each story starts with trust — and in the blockchain world, the trust starts with the network.
