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

The researchers behind the project have written over 90 papers on blockchain technology across a range of topics. This research is the backbone of Cardano.All transaction operations must be deterministic. It should only be possible for a transaction to be executed in one way if the system state is the same; factors that are external to the system should have no effect upon its computations. Similarly, you should not have scripts that work in two different ways in two different machines. The only solution to this is isolation - smart contracts and transactions must be independent from non-deterministic elements.платформ ethereum dance bitcoin takara bitcoin биржа monero bitcoin продать

If one Party A violates the terms, Party B can take Party A to court for not complying with the agreement. A smart contract fortifies such agreements in code so the rules are automatically enforced without courts (or any third party) getting involved.But others think the idea of an organization with decentralized control holds promise and are experimenting to bring it to life. The first such experiment, aptly dubbed 'The DAO,' was created in 2016 and ended up being a $50 million failure because of a technical vulnerability.

Thus, many bitcoin owners who use cold storage keep some tokens in a standard wallet for regular spending and put the rest in a cold storage device. This reduces the effort of digging out coins from the cold storage every now and then for everyday use. The practice of splitting the reserves is typically followed by exchanges that facilitate buying and selling of cryptocurrencies. These platforms deal with huge number of bitcoins (and other cryptocurrencies) and are often prime targets for hackers. To minimize the amount of loss in cases where security is breached, such platforms sometimes opt to keep a majority of their tokens in cold storage. These exchanges know the withdrawal trends and thus keep only that amount on the server to meet the requirements.Ключевое слово forum ethereum

However, there is no central source of truth; there are no oracles and there is no central public blockchain to which everyone independently commits transactions. Instead, every participant within the network constructs and maintains its own independent version of the blockchain based on a common set of rules; no one trusts anyone and everyone validates everything. Everyone is able to come to the same version of the truth without having to trust any other party. This is core to how bitcoin solves the problem of removing third-party intermediaries from a digital cash system.Ethereum's suggested Slasher protocol allows users to 'punish' the cheater who forges on top of more than one blockchain branch.daily bitcoin bitcoin prosto testnet ethereum tor bitcoin поиск bitcoin blogspot bitcoin bitcoin reindex cryptocurrency calendar bitcoin mac

Just wait for a second thought. There are quite a few drawbacks! bitcoin карты First, blockchain technology is decentralized. In simple terms, this just means there isn't a data center where all transaction data is stored. Instead, data from this digital ledger is stored on hard drives and servers all over the globe. The reason this is done is twofold: 1.) it ensures that no one person or company will have central authority over a virtual currency, and 2.) it acts as a safeguard against cyberattacks, such that criminals aren't able to gain control of a cryptocurrency and exploit its holders.pro100business bitcoin all cryptocurrency ethereum акции lurkmore bitcoin bitcoin rotator

bitcoin новости monero free p2pool bitcoin Let’s say a hacker wanted to change a transaction that happened 60 minutes, or six blocks, ago—maybe to remove evidence that she had spent some bitcoins, so she could spend them again. Her first step would be to go in and change the record for that transaction. Then, because she had modified the block, she would have to solve a new proof-of-work problem—find a new nonce—and do all of that computational work, all over again. (Again, due to the unpredictable nature of hash functions, making the slightest change to the original block means starting the proof of work from scratch.) From there, she’d have to start building an alternative chain going forward, solving a new proof-of-work problem for each block until she caught up with the present.bitcoin calculator
