EU targets digital markets and services with new restrictive legislation, could it be that decentralized digital markets and services are compliant by default?
Since Satoshi Nakamoto came up with the first conceptualized blockchain in 2008, that was an improvement on the system using a methodology similar to Hashcash which also led to the implementation of the first cryptocurrency Bitcoin in 2009, the blockchain has found a lot of uses in the business world. This is largely due to a lot of useful features inherent in the blockchain technology.
As we know blockchains are designed to be immutable.
Here we will design a simple blockchain that will help you understand how hashing makes a blockchain immutable with just a few lines of Java Code.
The most recent non-fungible token (NFT) boom may have you thinking that NFTs are all about digital art and collectibles. Well, for a brief period, they were - after all, who could ignore the infamous Beeple piece selling at Christie’s for $69 million?
In some blockchains validators are pre-defined, in others independent teams and individuals own the nodes. Game-based approach is an excellent way to choose validators wisely.
The Token Bridge decentralized application allows to safely cross tokens between RSK and Ethereum networks. It is available at tokenbridge.rsk.co for mainnet or testnet.tokenbridge.rsk.co for testnet.

Ethereum traded off decentralization for security and scalability. Developers came up with a slew of innovations collectively known as layer two solutions.
In the context of the coronavirus pandemic, governments are taking measures that, together with a general panic, weaken industry and financial markets. As in other areas, the largest conferences in the crypto industry are cancelled and projects are frozen. Bitcoin as the first and foremost cryptocurrency has also suffered from economic shocks, but what will happen next?
In our previous review, we made a detailed overview of Telegram Open Network and the specific features in the operation of key nodes (validators) of TON Blockchain. In this article, we will elaborate on one of the key aspects affecting the security and correct operation of the TON blockchain – a protocol allowing to achieve consensus between the network validators that are thoroughly described in the recently released document Catchain Consensus: An Outline authored by Nikolay Durov.
In this week’s article we’re going to continue our exercise in futurism and imagine a world post-4th industrial revolution. Taking Alain Demasio’s ‘regime of the trace’ as a starting point, we’ll take a detour into the era of the ‘deep fake’ before we enter into the age of the ‘deep truth’.
Affiliate marketing is a lucrative way for web users to leverage their network to generate additional income through third-party sales. Until recently, these partnerships were hard to establish in a way that proved mutually beneficial for both parties. Now, there is an alternative way for sellers to increase e-commerce sales and for independent marketing intermediaries to earn a commission. Splyt takes the guesswork out of affiliate marketing, creating a way for sellers to gain access to affiliate marketers without taking on additional monetary risk.
Blockchain is a very secure technology in theory but it hasn't enjoyed great PR recently. There's always news of a hack which begs to differ with the technology
Our identity is, without doubt, the most important asset we hold. In the digital age, our daily lives are fraught with dangers which undermine our identity or expose details of our personal lives we’d rather keep out of the public realm.
Open blockchain smart contracts does not have the capability to guarantee information reliability outside of their own network, they can only read the data saved on their respective blockchain. Oracles seeks to tackle this problem by providing a best-effort claims about the real world and feeding them to smart contracts in a trusted and secure manner, thus bridging the gap between smart contracts and the real world.
The most problem users come across is the internal JSON RPC error in Metamask. After a detailed search, I found there are numerous different solutions to it.
Governments are spending more and more resources on medicine every year, with the world’s drug development market amounting to more than 350 billion USD per year. On top of that, the World Health Organization is reporting almost 40 million confirmed cases of Covid-19 and more than a million deaths since the beginning of 2020. As such, this current pandemic will only cause a significant increase in the demand for vaccines; a market that exceeded 42 billion USD in 2019 and is predicted to grow more than 14.7% CAGR (compound annual growth rate) between 2020 and 2026.
Mastering how to create, read, update, and delete records from the blockchain is a skill you must understand. Yes, you can delete stuff from the blockchain...
For thousands of years, the "Byzantine Generals' Problem" was an un-answered riddle asking "how can two strangers trust each other without an intermediary?" Blockchain was the first-ever solution to this problem, enabling trust-less value transactions, leading to "decentralized applications" that take advantage of this to dis-intermediate everything from payment methods to word-of-mouth marketing, and more.
When I joined the university for my undergraduate course several years ago, I was excited that I am going to be an accountant thus handle money for big companies and work for the big 4 audit firms - EY, PwC, Deloitte and KPMG.
It is shortly after a successful bitcoin halving, that the news come in on Telegram stopping further development of TON blockchain, that it has been working on for the last 2.5 years. According to Pavel Durov’s official Telegram channel, the move is explained by US Court ruling, stating that TON blockchain is considered illegal, due to how easy it may be for US citizens to buy GRAMS, the token on which the TON blockchain is designed to run.
When compared to other options, the idea of locking funds in any way costs the user, but it benefits both the user and the system in terms of stability.
Network resource exhaustion can grind the entire blockchain down to a halt. As more people begin to rely on and use blockchain technology in their everyday live
The implementation of a cryptographic hash function is beneficial to prevent fraudulent transactions, double spends in blockchain, and store passwords.
Cloud has some benefits and some downsides. Hard Drives also have some benefits and some downside. Blockchain combines the both, leaving out the downside
When looking at Ethereum, there are some good things I can say about it and some bad. Ethereum did early stage investors in their ICO right, in the fact that the 2014 ICO price was $0.30.
Before developing your own blockchain, discuss with your team why you need it and what budget you can allocate to support it. You have to be alert to blockchain architecture and launch nuances. They can be easily missed, especially if you have underestimated the amount and complexity of work.

P2E is making waves in the gaming and crypto markets and is becoming one of the main targets for crypto investors. Despite their rising popularity, there is so much misinformation about the play-to-earn model that some clarifications are required to understand why P2E coins are important, and why not all of them are here to stay.
Blockchain was billed as a solution to many of the problems that traditional technology faces when it comes to connecting various parties from one end of the world to another, and it has done pretty well at that. However, certain issues linger, and the RIFT protocol helps to get that out of the way.
About a year ago I was excited to hear about the growing number of Decentralized Applications (Dapps) appearing on the EOS mainnet. I started to investigate these Dapps and came away disappointed. Most of the, so-called Dapps were traditional client/server web applications that simply utilized a blockchain component, called a smart contract that existed on the blockchain.
Crypto community has started to fight against censorship with the #ForkGoogle campaign asking the US Senate to subpoena Google. Members of the crypto community have started pushing back against censorship by tech giant Google and its media subsidiary Youtube. The community claims that the tech giant is censoring Bitcoin and crypto-related news applications while it is also ‘de-platforming’ crypto content contributors on YouTube.
For attorneys working with clients on their inheritance plans, what if you could create a digital inheritance and personal backup plan on the Blockchain?
The blockchain industry has been caught in a very limited mindset of how to judge a blockchain’s potential for meeting the needs of the modern digital economy. Transactions per second (TPS), the dominant unit for measuring the ability to scale, appears to be the only concern when designing blockchains.
Data is one of the most important tools of our time. Its usage is now pervasive throughout all aspects of society: from air transport to banking, construction to dentistry, from education to farming and beyond.
Tech investor, Visa Kannan, reflects on becoming a new NFT-owner. What the upside scenarios look like, the value NFTs bring and also if she would buy another.

This is the story of dOrg’s evolution from a few passionate engineers to a heterarchical network of builders developing industry-leading Web3 software.
In my opinion, the most important part of EOS is “OS”. After many architecture redesigns and refactoring, EOS became an excellent blockchain-based OS allowing projects to launch fast and secure blockchains with a flexible account system and fully functional smart contracts.
Global GDP rose by 2.2% in 2019, the slowest since the financial crisis of 2008 - 2009. Despite the impact of Covid-19, the global economy is expected to expand by 2.4% in 2020.
There are many different methods to verify a user’s identification. Although the management of authentication and active sessions has come a long way, simple password authentication has not been able to provide sufficient security to support the rapid growth in data, advancements in mobile and cloud technologies, and increasing volumes of security breaches.
The first time I laid eyes on a cold blockchain wallet, I was stunned. It wasn’t just the novelty of blockchain technology that shocked me, but the inherent vulnerabilities of wallets currently on the market. Where others saw secure pieces of equipment capable of safely storing millions of dollars in digital assets, I saw HSM formats, USB, ethernet cables, QR codes, and SD cards. In other words, I saw weak points that hackers could use to penetrate the wallets’ defenses, including WI-FI and bluetooth connections that made the notion of “air-gapped” computers laughable.
Each participant stores a tree of pending commands locally, in addition to the state variables viewNumber (starting at 1, stores the highest QC it voted to pre-commit), and prepareQC (starts at nil), lockedQC (starts at nil, stores the highest QC it voted to commit). When a “new-view” or round starts, a public function determines the leader from the current participants.
Before the widespread use of high-speed internet, distribution of software, music and movies was mostly anchored in physical media. Buyers of CDs and DVDs could sell the albums they no longer wanted or movies they had seen in secondary marketplaces such as eBay and Amazon or locally on Craigslist.
PoW is a simple and elegant consensus algorithm. Every node solves a simple cryptographic puzzle, whose solution is arrived at by making rapid guesses, and whoever guessed the right answer first is chosen to produce the next block on the network. That’s it.
Growing up in South Africa, the team at Wildcards witnessed first-hand the impact of poaching, pollution, poisoning and other forms of destructive human behavior leading to the extinction and endangerment of hundreds of animal species.
Long before the invention of Bitcoin, the computerized world has become dependent on open source developers. Some pieces of code such as Internet browsers, operating systems, and code libraries have become so essential that it is unanimously agreed upon that they should not be controlled by a single company, who might charge exorbitant fees for their usage, withhold the software from certain users for any reason, or do other nefarious things with the code.
Proof of work and proof of stake are the two most popular transaction validation methods on blockchains. Both have compelling arguments as to why they are more efficient, cheaper, more scalable or more secure, so let’s tackle what makes each different and why it matters.
Decentralization has become an inevitable process, not just in the crypto industry but far beyond it as well. This is easy to understand since users prefer full ownership of assets and freedom of action, instead of widespread interventions by third parties. It appears that the FBI understands the current trend and is ready to take preventive action.
How can decentralization change the face of gaming and what role does Cartesi play in bridging the gap between traditional software development and blockchain?
A dusting attack involves sprinkling crypto wallets with minuscule amounts of crypto to connect multiple addresses to a single owner. While these attacks are relatively new and nobody has really been able to say for sure what the exact motives behind them are, what is clear is that they represent a significant threat to privacy on the blockchain.
Despite the widespread controversy in the aftermath of the 2016 U.S. election, the public generally isn't aware that the term 'fake news' hardly captures the full extent of information manipulation on social media.
Now that NFTs are back on the rise, many investors are trying to find a way in, but it can be hard to identify value in the enigmatic world of collectibles.
This article discusses how financial regulators can regulate smart contracts in such a way that the adoption of the blockchain is feasible. I will argue that to regulate cryptocurrencies without destroying it, fungibility must be maintained, and it must be treated as money.
Blocknet Protocol is a blockchain-agnostic platform designed to help developers launch new applications using features from various blockchains. If developers want to build on EOS but use smart contracts from Ethereum, they can with Blocknet.
We are all familiar with digital currencies such as Bitcoin, Ethereum, and EOS. The development of digital currency to the present has gone through a special development stage, during which the prices of various digital currencies have skyrocketed and attracted countless people.

A better alternative being proposed in many research papers is using biometrics to allow access. Crypto-Biometrics is a combination of mathematics, cybersecurit
As the world changes, so do its driving forces. When the war was the most universal language between the kingdoms, the arsenal, the weaponry was the main focus of engineers and scientists. And when the world realized the economy and prosperity would make a lot better medium, they shifted their attention to financial technology.
Analysis of transaction fees has long been overlooked in the blockchain area, with the first papers in the academic literature being published from 2014 (Houy) onwards.
Houston, Texas “Would you ever invest in something you don’t understand?” Spencer Randall asked me. It is a compelling question, one of the challenges preventing mass cryptocurrency adoption. “People don’t understand Bitcoin and other cryptocurrencies. That’s why we’re here to share our insights, analysis, and make more people aware of this asset class.”
It has been almost three years now since we last heard the promises of mass adoption, usability, scalability, proof of X and all those phrases no one really understood. While others saw that time as a period of prosperity, I would have to disagree and point out a few flaws in the system.
Blockchain industry is developing at a very high pace of innovation, adjusting and tuning its parameters, trying to find its market fit. There are thousands of projects available on the CMC, but just a few really worth a bigger attention. Lets try to briefly review the industry, its trends, where we are heading, and how Hybrid platforms (priv+pub) fit into a bigger picture.
The idea of blockchain was first introduced in 1991 by Stuart Haber and Scott Stornetta. It was not until 2008 that the first blockchain was conceptualized by Nakamoto Satoshi and created Bitcoin. Since then, numerous projects emerged hoping to revolutionize the blockchain space.
Blockchains are notoriously challenging network structures to scale, both in performance - such as latencies, throughput, and number of validators - as well as in feature sets - such as customizability of the bytecode that the blockchain executes.
With the third episode of our shared journey, we will uncover the meaning of the hashing function, share a ride on the Avalanche effect, and much more!
While regarding how to form a DAC, people are too optimistic or ideal. It seems DAC will start from scratch by itself when connecting people (it's definitely not, remember the Guild that the Mandalorian has joined, it is a typical DAC, you can see how complicated it is), no clear path was given or discussed so far. DAC would be the mainstream value creation entity in the Value Internet Era.
In the last two posts, I tried to give information about IP rights in general and discussed patent rights and if they fit in tokenization. If this is the first time you check my page, I recommend you to check my last two articles: here and here .
Nowadays Blockchain is becoming a very powerful technology due to its unique advantageous features as immutability, decentralization, distributed and shared database or ledger.
While Bloomberg has celebrated the best decade in history for financial returns, it is not a coincidence that wealth inequality has reached proportions not seen since the roaring´20s. And while this does not seem to concern the financial elites — who celebrated another fat end of the year — this is in reality a major concern for all the others, the 99,..%ers.
In 2020, apart from falling cryptocurrency prices following the stock price due to being dragged by the coronavirus, we see some news in the blockchain industry that is quite encouraging for us in terms of innovation and economic growth potential.
The word “blockchain” is still surrounded by hysteria: companies that simply enter in it, their name soar in price by 400%. Half of the world would like to receive cryptocurrency as a gift for the New Year, while Bitcoin is called "the largest bubble in the history of mankind." A dozen new terms, some fascinate with innovation, others - scary, resembling a scam. I will explain in simple terms why bitcoin and blockchain are not the same things, how technology will make the world transparent and who will benefit from it.
Decentralized finance dApps (DeFi) are, without a doubt, the way we can see real progress being made in regard to the general adoption of cryptocurrencies. As we know them now, cryptocurrencies are still climbing the adoption curve.
‘Corona virus’ (or COVID-19 as it is formally known) is the foremost topic on everyone’s mind today. Scanning our social media feed or checking the official website to stay updated with the latest news regarding the disease has almost become second nature. No dinner table discussion and no phone conversations is complete without a reference to the mayhem this disease has left in its wake.
The main network is running, transactions are being sent, the wallet is working. What's next? In this article, we will consider how to maintain a network and solve its problems.

“The blockchain cannot be described just as a revolution. It is a tsunami-like phenomenon, slowly advancing and gradually enveloping everything along its way by the force of its progression.” In these words, William Mougayar, one of the greatest proponents of blockchain, praises the colossal impact of the decentralized ledger on everything.
As blockchains flourish on their way to pollinating the world economy with the power of distributed ledgers, interoperability between networks becomes essential to sustaining this paradigm shift.
These stories are from a two-part project. While this part is science fiction, the other part is about reality. Both parts are about mobile, blockchain, and cryptographically secure voting in the context of the US election system. (Reality Piece: link).
Industries and governments are continuously seeking ways to optimize the movement of goods, data, and currencies across global supply chains. Global growth needs a jumpstart.
The explosion of content on the world wide web, social media and chat networks greatly increased the interest in sentiment analysis from a growing number and variety of interested parties.
So, you have chosen the engine and implemented the first version of your blockchain. Now, full-scale testing is required to test the network stability under changes. Potential users and validators will be able to prepare their services in advance for real conditions if there’s a test network (or testnet) - the most complete copy of the main network.
Admit it! Startups are hard, why? Because in startup space we are looking at a problem that no one is solving or an incumbent is making lives miserable there and we improve the state, we add value, we find a new business model while doing so and somehow make that startup - now turned into a business - self sustainable!
One of the most important aspects of any blockchain network is the consensus algorithm that is used to validate transactions. In centralized systems like Visa and MasterCard, transactions are verified by a host of authorities. On the other hand, in a decentralized system like blockchain, the network nodes need a set of rules to help them arrive at consensus
regarding the authenticity of new transactions. This is where the consensus algorithm comes in.
TLDR: IBCO is the new primitive for crypto projects funding, solving for the main issues of ICOs such as lack of accountability, lack of liquidity and flawed price discovery mechanics for the token itself.
This is a two-part project. This part is about reality. The other part is science fiction. Both are about mobile, blockchain, and cryptographically secure voting systems in the context of US elections. (Science Fiction: link)

It's the end of the world as we know it, humanity is programmable and our operating system is getting a reboot. The question is when the system is back online what will be in its place?
In the morning, we rub our eyes and stretch ourselves, ready for a new day. After washing,we open the refrigerator, take out the sandwiches and milk we bought last night, put them in the microwave to heat up, and perhaps go to the living room to open the meditation videos stored in the tablet and relax with the rhythm of music.
For the last three years, the hype in blockchain space went from its highest ever to the lowest point. There are a lot of niches where blockchain technology found its product market fit, such as exchanges, cross-border payments, grey market financial operations, DeFi (not quite yet, but it works). But there are still tons of areas where it didn’t.
tldr; This post is a brief look into the different aspects (good, bad, and ugly) of the XRP token and Ripple Labs, the company. It is important to separate the two while also investigating the indisputable overlap between the token and the company.
In this article, we’ll be taking a look at the top trends that are currently emerging within the blockchain space, touching on the companies that are at the for
Tezos certainly stands out from the mass of the many ICO projects of 2017 due to the continuing positive financial development of its token. This alone makes it interesting to deal with the Tezos project. A look at the basics of the project should help to understand if the chances for a further good development of the project are positive or if there are obvious dangers or bigger obstacles and a lot of Hopiom is involved.
Viewers of popular HBO sitcom Silicon Valley would already be familiar with the idea of Decentralized Internet. Termed as the ‘new Internet’ in the series, the lead characters conceive a decentralized peer-to-peer (P2P) network built using smartphones. They even create their own coin and launch an ICO.
You walk into a coffee shop and want to start your day with a grande Cappuccino. The barista starts making your coffee, and you’re sitting at your table, staring at the birds chirping outside the window.
The launch of Telegram Open Network mainnet has been delayed till early 2020, meanwhile, the testing of TON blockchain is in progress. Test network has been relaunched on 15 November 2019.
Every man is born equal. That’s how our parents and grandparents always kept us in check. Based on the promise of equality they wanted to push us to our very limits.
In this article, we propose a blockchain network that acts as a centralized append-only distributed file system (DFS) such as Hadoop Distributed File System (HDFS) or Google File System (GFS). The potential advantages of blockchain as a distributed file system (BaaDFS) include:
As of today, there are over 24 layer-1 blockchain projects just within the first 100 listings in coinmarketcap.com. Guess, what? Each of them claims to be the “next-big-thing”, still they are just a broken iteration of one other.
Kailin O'Donnell is the Director and Co-Founder of NEM Ventures, the VC and Investments arm of the NEM Blockchain Ecosystem. Kailin is a DLT advocate who has been deeply involved in NEM since before launch, coding some early SDKs for NIS1 and Symbol, and has assisted multiple companies building on the NEM blockchain.
This week I asked a few blockchain founders a different question (the previous interviews can be found here). All of the founders I talked with are from different niches, including infrastructure projects, crypto trading tools, blockchain-based social apps, and more. If you’re someone who monitors the blockchain field, then you’ll definitely want to bookmark this article so that you can see which answers became a reality at the end of the year.
Blockchain economies exist in cyberspace and regular economies exist in geographical space. Cyberspace is inherently different from geographical space. That said, we believe it is not a stretch to assert that a blockchain fits the definition of an economy.
In today's world of cancel culture, doxxing, and collusion between tech companies and government agencies to harass and interfere with businesses that offend their delicate sensibilities, there is a need for the ability to conduct online business in a way that protects the privacy of the business, its employees, suppliers and customers.
