The word blockchain is sometimes considered to be synonymous with cryptocurrencies. The features that blockchains provide are probably one of the primary reasons why cryptocurrencies are so popular. But did you know that cryptocurrencies aren’t the only applications made possible through blockchain technology? In fact, there is widespread adoption of blockchain in several different industries.
The following article will cover some of the most popular blockchain applications, beyond just cryptocurrencies.
We’ll cover the following topics:
What is blockchain?
Blockchain Applications
Blockchain in supply chain management
Blockchain in cybersecurity
Blockchain in voting
Blockchain in financial services
Blockchain in the loyalty referral program
Blockchain in music
Blockchain in weapon tracking
Now, before we go into some blockchain applications, let’s have a look at what exactly blockchain is.
What is Blockchain?
Blockchain is a list of records or “blocks” that stores data publicly and in chronological order. The data—the records within these blocks—are secured using cryptography and don’t have a central authority controlling them. Everyone within the network has access to these blocks and has copies of it; but once something is recorded into the blockchain, the data cannot be altered. Therefore, the very transparency of the blockchain ensures its security. While some argue that the technology is still in a hype cycle, other research indicates that Blockchain is starting to take off in businesses. According to IDC, corporate and government spending on Blockchain technology is expected to jump 89% percent over 2018 numbers, hitting almost $3 billion in 2019. This number is estimated to reach more than $12 billion by 2022, which means there will be plenty of demand for blockchain experts. Let’s look a how blockchain is already showing up in a few industries.
So, now that you know what a blockchain is, let’s go into some blockchain applications. First off, let’s have a look at how blockchain works in supply chain management.

Blockchain Applications
1. Blockchain in Supply Chain Management
Imagine you’ve ordered some apples from an online shop. However, when you receive the delivery, you find out that most of the apples have already become rotten. Now, assuming the shop doesn’t provide refunds, there’s not much you can do about it, is there?
But what if there was a way that this whole thing could have been avoided?
Such problems can be avoided with blockchain technology, as it facilitates traceability across the entire supply chain. Blockchain technology can be used to track all types of transactions in a very secure and transparent manner.
These benefits include:
blockchain-benefits
Let’s have a look at an example of supply chain management:
farm-storage
In supply chain management, blockchain provides permanent record-keeping, transparency, and validation of transactions shared by multiple supply chain partners. With this, anyone can verify the authenticity or status of the product being delivered.
Now, let’s have a look at a real-life example of this blockchain application:
walmart
Walmart is building a blockchain distributed ledger in order to connect and track pork suppliers, shippers, purchasers, and others involved in delivering the food product around China. Here, blockchain reduces the risk of data tampering or inaccuracy.
2. Blockchain in Cyber Security
Imagine person A is sending 20 dollars to B. Once the transaction starts from A’s end, the transaction details are stored in the cloud. Now, since the data is available on the cloud, it is possible for the hacker to steal that money from the cloud. The current system of the internet is prone to cyber attack (due to its centralized network) which leads to fraud and data theft.
How would things be different with blockchain?
Here are some cybersecurity advantages of adopting blockchain:
cybersecurity advantages
Let’s have a look at how this same transaction would be performed using blockchain.
Again, A is sending 0.0025 bitcoin, or BTC (approximately equivalent to 20 dollars) to B. This time, the transaction is recorded into a blockchain. Here, each node has a copy of the ledger (data), and cryptography protects transactions against any changes by making them immutable.
Now, were a hacker trying to hack in the blockchain, his efforts would be in vain. Using blockchain, it’s easy to prevent malicious attacks due to the peer-to-peer connections where data cannot be altered or tampered.
Let’s have a look at a real-life application of this blockchain application. Mastercard is using blockchain for sending and receiving money. Also, it allows exchanging the currency without the need for a central authority.
Now, let’s have a look at the next blockchain application: voting.

3. Blockchain in Voting
Now let’s have a look at the current voting process. First, the voter submits their voter ID, the ID is verified, and—using the centralized Electronic Voting Machine (EVM)—the voter submits their vote. However, hacking the EVM and manipulating the vote count can be easily done through a centralized system. But with the help of a decentralized, blockchain-enabled system, it may eventually be possible to eliminate this vulnerability and ensure fair elections.
Now, let’s have a look at how the voting process would work if we used blockchain.
First, the voter downloads a voting application, such as MiVote. Then, the user submits their voter ID to register for the election. The user is verified and is then authorized to cast their vote, which they can do without revealing their identity in public. Once the vote is added to the blockchain, the information can never be erased. Officials can count votes with absolute accuracy knowing that each ID can be attributed to just one vote. Moreover, using blockchain, voters are also able to track their votes.
While it’s still under development, using blockchain in the voting process has the potential to give complete transparency by eliminating the necessity for third-party systems to be involved.
Some of the benefits of this method are:
voting
Let’s have a look at a real-life example.
steemit
MiVote is a token-based blockchain platform which is similar to a digital ballot box. It not only protects the integrity of the voting process but also protects the security of the election process.
Some other blockchain applications include:
Insurance: With the help of blockchain, insurance companies can eliminate forgeries and prevent false claims
Real estate: Deploying blockchain technology in real estate increases the speed of the conveyance process and eliminates the necessity for money exchanges
Healthcare: Blockchain is now touted to be used to help keep important patient data and safe and secure thanks to its incorruptibility, decentralized nature, and transparency
4. Blockchain in Financial Services
Many financial services firms are using Blockchain to improve back-office settlement systems, increase efficiency, and reduce costs. Banks like UBS have plans to use tokens for cross-border trades. While the Chamber of Digital Commerce was established to educate and advocate for Blockchain technology in the financial services industry and beyond. The chamber's initiatives include the Blockchain Alliance, which aims to use it to combat criminal activity. And, the Blockchain Intellectual Property Council, which helps to balance identification transparency with protecting proprietary data.

5. Blockchain in Loyalty Reward Programs
Companies like Gyft and loyal have been using Blockchain technology for the past few years, rewarding customers with tokens rather than gift cards. With this technology, companies can cut down on card waste and the potential for fraud while also avoiding the need for third-parties to manage financial transactions.
6. Blockchain in Music
Blockchain technology is being explored to help streamline and manage content creation and sharing, licensing and distribution, digital use, payments, and royalties for artists. Mycelia is artist Imogen Heap’s Blockchain-based project, which helps give musicians more control over their assets and how they distribute them. Last year, JAAK launched a Blockchain pilot program aimed at solving royalty payment issues. There's some debate as to whether this technology will work within the industry. Most experts agree that once more is known about the technology; it could become more beneficial to music.
7. Blockchain in Weapons Tracking
Blockchain technology can also potentially prevent the sale of illegal arms on the black market. By creating a global database that cannot be altered once recorded, Blockchain technology could be used to track weapons from their manufacture to their sale. The database could primarily record every transaction and purchase.
Some other blockchain applications include:
Insurance: With the help of blockchain, insurance companies can eliminate forgeries and prevent false claims
Real estate: Deploying blockchain technology in real estate increases the speed of the conveyance process and eliminates the necessity for money exchanges
Healthcare: Blockchain is now touted to be used to help keep important patient data and safe and secure thanks to its incorruptibility, decentralized nature, and transparency

By tracing this history, we can understand the motivations behind the movement that spawned bitcoin and share its vision for the future.bitcoin автоматически Smart contracts are tools that can automatically execute transactions if certain conditions are met without requiring the help of an intermediary company or entity. They are often associated with Ethereum, a blockchain that was designed to accommodate smart contracts, but the idea isn’t restricted to any particular platform or network.Central to the Bitcoin system is the concept of 'mining,' which will be explained in greater depth in the next section. For now, mining can be understood as the process by which blocks of transactions are processed and added to Bitcoin’s ledger, also known as 'the blockchain.' 'Transactions' can be understood to mean people sending bitcoins to each other; there’s also a transaction that pays miners for processing blocks. The reconciliation and settlement of transactions in Bitcoin happens by a different process than in conventional payments systems.segwit bitcoin fpga ethereum

alpha bitcoin The MIT Digital Currency Initiative funds some of the development of Bitcoin Core. The project also maintains the cryptography library libsecp256k1.This form of cold storage confers enormous security advantages. The user is more or less invulnerable from cyberattacks and malware because it is simply not possible to access a user's private key via those avenues. Of course, the safety of these physical documents cannot be entirely guaranteed either—if a would-be hacker discovers the location of your paper wallet and physically steals it, they can access your bitcoin holdings. Some users hide or disguise the paper wallet. The paper wallet should also be protected from physical damage; if the keys fade and can no longer be scanned, the user will never again be able to access the bitcoins sent to that address. Even using the incorrect type of printer (non-laser printers can allow the ink to run, for example) may damage the paper wallet.ethereum transaction bitcoin биржа бесплатный bitcoin bitcoin vip fasterclick bitcoin арестован bitcoin bitcoin analysis icon bitcoin яндекс bitcoin

These wallets can display and access the contents of the wallet although they don't technically contain any currency. Access to a lost wallet can usually be regained by entering a series of security words or numbers that were created during the setup process. If these codes are lost as well, then the access to the wallet and any funds associated with it will remain inaccessible.Cryptocurrencies use advanced cryptography in a number of ways. Cryptography evolved out of the need for secure communication methods in the second world war, in order to convert easily-readable information into encrypted code. Modern cryptography has come a long way since then, and in today’s digital world it’s based primarily on computer science and mathematical theory. It also draws from communication science, physics and electrical engineering. ethereum обмен

This is particularly problematic once you remember that all Bitcoin transactions are permanent and irreversible. It's like dealing with cash: Any transaction carried out with bitcoins can only be reversed if the person who has received them refunds them. There is no third party or a payment processor, as in the case of a debit or credit card – hence, no source of protection or appeal if there is a problem.I can’t lie to you — it’s expensive. Smart contract and token developers can charge a lot of money because there aren’t many of them in comparison to how many ICOs they are. You can expect rates to start from around $100/hour, although some can charge a lot more.bitcoin accelerator hack bitcoin usa bitcoin bitcoin fasttech bitcoin презентация electrodynamic tether видео bitcoin

Proof-of-Work is the layer that is closest to the bare metal, connecting hardware and physical resources to create distributed machine consensus. Proof-of-Stake may be useful for coordinating dynamic human behavior in such a system, once immutability of the underlying ledger and asset is guaranteed by Proof-of-Work.lealana bitcoin
