Secure Internet Of Things Networks
The Internet of Things is making our lives easier, but it’s also opening the door for nefarious actors to access our data or take control of important systems. Blockchain technology can provide greater security by storing passwords and other data on a decentralized network instead of a centralized server. Additionally, it offers protection against data tampering since a blockchain is practically immutable.
Host Your Site Without Any Central Server
You need website service when your site is down. In most cases, the outage is due to server overload. Would it be good if your online content does not require any central server?
Zeronet creates an entirely . It aims to sidestep the need to host websites on servers by stashing website information across the internet in small pieces. Next, they are linked together using a blockchain registry. This eliminates web hosting costs and always accessible.
Which Industry Can Benefit From Blockchain
Almost all the sectors out there can benefit from the blockchain. Out of all the sectors out there, the four sectors that we think benefit the most include Energy, Real Estate, Logistics, Healthcare, Finance, and Government.
There are already many companies using blockchain technology actively after realizing the potential of this tech. To get a glimpse of exactly how different industries are taking benefits of blockchain, lets briefly go through each one of them.
Benefits of Blockchain In Energy Sector
Energy distribution, allocation, and production have always been an important sector for governments out there. Without proper energy management, it becomes hard for any government to provide valuable growth to its economy. Private players also play a crucial role and can benefit from the blockchain. Below are the benefits that the energy sector receives with the use of blockchain.
- Environmental Sustainability: Blockchain helps make the energy sector more environmentally sustainable. It helps overcome legacy energy sector efficiency issues and provides a network where it is possible to produce, store, and distribute energy more efficiently.
- Reduced Costs: The costs associated are reduced when it comes to infrastructure and operational aspects of the energy sector.
- Improved Transparency: The use of a distributed ledgers improves transparency.

Blockchain Technology: A New Way To See The World
Our world is centralized. If you look around yourself, you will find tons of services that use centralization to power their whole process. The bank that you visit to deposit or exchange money is centralized and they hold the ownership of your assets in more ways than you can think of.
Blockchain technology is here to break the shackles of centralization and provide better options to the end-users. At the core, blockchain is a decentralized, peer-to-peer ledger-based network where there is no central authority.
The core idea of decentralization is what makes blockchain technology so popular. It is now being used in different sectors to improve their state.
To ensure decentralization, the network deploys some key things to make the decentralization work.
- Each peer takes part in maintaining the network. Each peer also has a full ledger copy.
- The network also utilizes a consensus method that validates transactions.
- Mining mechanism is also provided to peers where they need to participate in the consensus method by following the rules of mining.
If you are new to blockchain, then we recommend checking out our detailed guide on the blockchain that we have crafted for beginners: Blockchain For Beginners: Getting Started Guide.
Limit On Transactions Per Second
Given that blockchain depends on a larger network to approve transactions, theres a limit to how quickly it can move. For example, Bitcoin can only process 4.6 transactions per second versus 1,700 per second with Visa. In addition, increasing numbers of transactions can create network speed issues. Until this improves, scalability is a challenge.

What Does A Block In A Blockchain Mean
As the name implies, a blockchain is a system made up of a series of blocks. A Blockchain’s chains are made up of a number of blocks, each of which contains three fundamental components. The data in the block is the block’s starting data. Following that is the nonce, which is a 32-bit whole number. When a block is constructed, a nonce is generated, as well as a block header hash. The final stage is the hash, which is a 256-bit value connected to the nonce. The cryptographic hash is created by the nonce, which is created when the first block of the chain is established. The data in the block is deemed allocated to the nonce and is permanently associated with it.
Limitations Of Blockchain Technology
Limitations are as follows:
- Poor adoption
- Impossible to make revisions when needed, for instance, in case there is a need to make an amendment to change payment.
- Loss of private key due to poor management, which means loss of data or money in case of cryptocurrencies.
- Delays in development, sharp differences and back-forth communications that are required to attain a consensus can consume a lot of time leading to delay in upgrades and development.
- Double-spending problem
Integrating blockchain means offering your current operations on the blockchain or porting them over to blockchain.
Three things you will need to think about when implementing blockchain is scalability the extent to which the blockchain network can accommodate as many users and features as possible without losing speed and security decentralization the speed of transactions and security.
In most cases, you may find the need to balance security, decentralization, and scalability.
Never assume blockchain will do some magic. It may take time to give results and maybe it will improve only some aspects and not all of it. Make sure to use tried and tested software, never rush to an idea, and explore the possibility of partnerships with your suppliers and other companies in implementing blockchain.

Keeping Your Id And Personal Information Secure
Currently, your healthcare records may be printed on paper. Perhaps theyre also stored on a central server at a hospital. But these records can be hacked, altered, or stolen. Maybe this has never happened to you. Count yourself lucky.
A CBS news report showed that A breach at Anthem Insurance affected 78 million people, and a hack at UCLA Health exposed more than four million patient records.
Take note: these are not only adult records. The report goes on to list many black market healthcare record sellers, saying one seller offered children’s health records for sale. And what happens to these records?
Social Security numbers sell for $1, and credit card info goes for up to $110. But Experian reports full medical records can command up to $1,000 because they’re an identity thief’s dream: date of birth, place of birth, credit card details, Social Security number, address, and emails.
Imagine if your identity was stolen, or that of your child. The damage to your financial future or that of your child will be significant.

In 2008, an author using the pseudonym Satoshi Nakamoto wrote a white paper describing Bitcoin, a new decentralized cryptocurrency.8 Unlike past attempts at forming a cryptocurrencyattempts that relied on preestablished trusted entities for the system to operate correctlyBitcoin’s design runs on the open Internet, with no one in charge, while maintaining tight security. While the building blocks of Bitcoin were not novel, the composition of these properties into a single system was a meaningful contribution,9 and Bitcoin became the first cryptocurrency to achieve widespread attention.
In response to Bitcoin’s success, the technology was quickly dissected to understand how it works and what is new about it. Its most innovative component has been labeled blockchain technology, a decentralized mechanism for participants to agree upon data and computation.
Technology news commonly leaves the cheery impression that blockchain technology reduces or even completely eliminates the need for trust. The use cases of such an innovation stretch the imagination. Occasionally, there is a contrarian take.12
The truth is, trust is complicated. Blockchain technology does eliminate specific, narrow reliances on trust, but it also requires new assumptions that might be better or worse for specific use cases. Thus, there are not many single-sentence talking points that will be accurate about blockchain technology’s efficiency, security, cost, etc.
How To Evaluate Potential Blockchain Use Cases
So how do we evaluate when we need a decentralized database, or specifically a blockchain?
Whichever factors are at play, one should implement only the minimum level of decentralization required to meet those needs, because decentralization itself is expensive. For example, a fully decentralized system is probably necessary for censorship resistance but may be overkill for generating adoption. When a fully decentralized system is needed, a blockchain is the only known solution.
We suggest the following checklist for evaluating suggested use cases:

Is Blockchain Good Or Bad For The Environment
Blockchain uses vast amounts of energy, but it has the potential to save vast amounts of energy, too. We examine the positive and negative effects of blockchain on the environment.
At the dawn of the Industrial Revolution, humanity faced one of the biggest dilemmas of its entire history for the first time: Are the benefits brought by technology advancement worth the environmental damages it causes? This quandary has eventually become the mainstay of our current age, as humanity has grown more and more dependent on its newest technologies. Back then, electricity and fossil fuels reshaped the world we lived in, while today, in less than two decades, interconnectivity has forever changed the way we think and live.
Blockchain technology is among the most controversial inventions brought by the Digital Revolution. Its vast potential is still largely untapped, with way too much attention focused on mining cryptocurrencies rather than using it for more… enlightened purposes. The immense amounts of energy required to fuel mining made blockchain become the villain in the never-ending struggle of technology vs. nature. However, a few brilliant minds have devised some curious and interesting solutions to use this technology for a better planet as well. Let’s have a look at some of the pros and cons to the blockchain technology and its environmental impact.
What Is Blockchain Used For
Blockchain is most frequently associated with cryptocurrency and NFTs, but its numerous applications go far beyond that. Blockchain has already had a marked impact on several sectors of the economy thanks to its novel use in solving issues of transparency and cost in data processing.
After all, any kind of data can be stored in a blockchain, not just financial records.

Blockchain For Social Impact: The Good Bad And In Between
From a bumpy beginning in1993, the internet evolved and morphed into technology that changed modern life. From a bumpy introduction to the public in1993, the internet evolved and morphed into technology that changed modern life.
In 2009, Bitcoin and therefore blockchain slipped into existence with relatively quiet fanfare. Blockchain technology is now one of the watchwords of the 2020s, alongside cryptocurrencies. The chatter is reaching a crescendo.
Whats behind the hype? Many fans claim blockchains potential could reshape financial systems and alter global power structures. Others think it could hasten climate change. Lets consider blockchain for social impact, from its ability to reforest to financial inclusion.
Who Invented Blockchain
Blockchain technology was first outlined in 1991 by Stuart Haber and W. Scott Stornetta, two mathematicians who wanted to implement a system where document time stamps could not be tampered with. In the late 1990s, cypherpunkNick Szabo proposed using a blockchain to secure a digital payments system, known as bit gold .

Freedom Ack To People
New Technical Civilization can be formed with the use of blockchain technology. The people can take back their freedom because there is no central governing system and is fully decentralized. It is entirely immune to the danger of third parties and centralized systems. Transfer of values and services can happen at a global level and on a worldwide scale using the decentralized networks, which can also remove the requirements of any government.
Reducing Cost Of Cross
Banks and other organizations experience the high cost of cross-border transactions. For instance, most of these transactions take a model 3 days or longer to complete. Organizations such as Ripple whose network is now available in over 40 countries and six continents, are now using blockchain and cryptocurrencies to overcome these barriers. Blockchain helps achieve near-instant cross-border transactions at a fraction of cost.

Provide Untampered Votes During Election
Some common ways a country vote is through a paper-based system or e-voting via a machine in a polling station or i-voting through a web browser. There are always doubts about the voting system ability to secure data and defend against potential attacks. After all, every vote counts have a huge impact on a country.
Voatz provided a voting platform to ensure transparent and verifiable elections around the world. In preparation for the 2019 Municipal Elections, Voatz provide a pilot blockchain mobile voting to deployed military personnel and overseas US citizens.
Ballot received was a 98% successful return rate. Mobile voter turnout rate was a high 90%. We are not far away to use this technology for future elections.
Is Blockchain Secure
Blockchain technology achieves decentralized security and trust in several ways. To begin with, new blocks are always stored linearly and chronologically. That is, they are always added to the end of the blockchain. After a block has been added to the end of the blockchain, it is extremely difficult to go back and alter the contents of the block unless a majority of the network has reached a consensus to do so. Thats because each block contains its own hash, along with the hash of the block before it, as well as the previously mentioned time stamp. Hash codes are created by a mathematical function that turns digital information into a string of numbers and letters. If that information is edited in any way, then the hash code changes as well.
Lets say that a hacker, who also runs a node on a blockchain network, wants to alter a blockchain and steal cryptocurrency from everyone else. If they were to alter their own single copy, it would no longer align with everyone elses copy. When everyone else cross-references their copies against each other, they would see this one copy stand out, and that hackers version of the chain would be cast away as illegitimate.

What Is A Blockchain
A blockchain is a distributed database that is shared among the nodes of a computer network. As a database, a blockchain stores information electronically in digital format. Blockchains are best known for their crucial role in cryptocurrency systems, such as Bitcoin, for maintaining a secure and decentralized record of transactions. The innovation with a blockchain is that it guarantees the fidelity and security of a record of data and generates trust without the need for a trusted third party.
One key difference between a typical database and a blockchain is how the data is structured. A blockchain collects information together in groups, known as blocks, that hold sets of information. Blocks have certain storage capacities and, when filled, are closed and linked to the previously filled block, forming a chain of data known as the blockchain. All new information that follows that freshly added block is compiled into a newly formed block that will then also be added to the chain once filled.
A database usually structures its data into tables, whereas a blockchain, like its name implies, structures its data into chunks that are strung together. This data structure inherently makes an irreversible time line of data when implemented in a decentralized nature. When a block is filled, it is set in stone and becomes a part of this time line. Each block in the chain is given an exact time stamp when it is added to the chain.
Logistics And Supply Chain Tracking
Using blockchain technology to track items as they move through a logistics or supply chain network can provide several advantages. First of all, it provides greater ease of communication between partners since data is available on a secure public ledger. Second, it provides greater security and data integrity since the data on the blockchain can’t be altered. That means logistics and supply chain partners can work together more easily with greater trust that the data they’re provided is accurate and up to date.
