How Can Blockchain Be Used in the Real World?
In reality, blockchain technology could be used in practically every industry or sector. By replacing centralized servers with that of a decentralized blockchain, individuals, companies and even governments could benefit from all of the advantages that the blockchain offers, such as security, transparency, and speed!
I am afraid I can’t go through every single industry that the blockchain could be used for, so I will list five of my favorites!
Cross-Border Payments
The cross-border payments industry is a multi-trillion dollar business, with banks needing to send international payments on a daily basis. The majority of this is handled by a third party called SWIFT, who are based in Belgium. SWIFT were set up in the early 1970s to make international payments easier, however the system is slow, expensive and inefficient.
This is because banks are not able to transact with each other directly. Instead, they have to use SWIFT and in some cases, additional correspondent banks. However, by using blockchain technology, banks would be able to do business on a peer-to-peer basis.
This means that there is no third-party intermediary sitting in between the two organizations. Transactions would no longer take days, nor would they cost lots of money! The Ripple blockchain was designed exactly for this purpose and they already have more than 100 different banks testing out their protocol!
Compare Crypto Exchanges Side by Side With Others
Did you know?
Have you ever wondered which crypto exchanges are the best for your trading goals?
Elections
How many times do we hear about election fraud? Whether it is the centralized network of the U.S. election being hacked (allegedly!) or governments who threaten their citizens with violence if they don’t vote for them? Unfortunately, this happens all the time, but blockchain technology could solve the problem!
Firstly, as every single transaction that has ever occurred is available to view on the public ledger, it would be impossible for a political party to change or remove votes. Remember, the blockchain is not only for financial transactions, as it can process anything that is considered data!
The blockchain would also be perfect for elections as transactions are pseudonymous, meaning that nobody would know the real-world identity of the voter. Instead, a citizen’s identity could be linked to a private key that only the individual user has access to. This would ensure that the citizen can only vote once!
Supply Chain
A supply chain is how goods move from their point of origin to their final destination. An example of this is an orange juice drink. The supply chain starts at the location where the orange was grown, it might travel to a factory to be turned into juice, then it might travel to the warehouse, and finally, to the supermarket.
At the moment, it is very difficult to trace each individual stage of the journey, as each part of the supply chain uses its own centralized systems. However, by using blockchain technology, the entire supply chain process could be available for all to see.
This would be a lot more efficient, transparent and secure than using centralized servers, as everything could be put on to the same network. Furthermore, the network would never go down and it is fraudproof!
Gambling
The online gambling industry is worth billions of dollars each and every year. Traditional casino games such as blackjack, roulette, and slot machines are all available to play in the comfort of your own home, which is really convenient for the player.
However, as online casinos normally keep their gameplay data behind closed doors on their centralized server, there is never any guarantee that the casino is truly playing fair.
By using blockchain technology, gaming outcomes can be independently verified on the public ledger, meaning that the system and data would be completely transparent. This could also be used for national lotteries, too!

Insurance
The insurance industry covers practically everything on Planet Earth. Whether it’s your home, car, pet, health, holiday or phone — if it has value, it can be insured!
The problem is that the industry is dominated by third-party intermediaries, which means that taking out a policy is expensive and when it comes to making a claim, it’s a very slow process. However, the blockchain protocol would allow somebody to get insured without needing a third party.
For example, if somebody wanted to ensure their flight, as soon as the plane actually takes off, the outcome could be settled automatically. Either the plane takes off on time and you lose your insurance payment, or the plane is late and you receive a payout!
This could all be done in a transparent, fast and secure eco-system, such as the blockchain!

After its price skyrocketed in the fall of 2013 and after the spectacular crash in early 2014, more and more people became interested in this 'cryptocurrency,' and some of them even started mining it.While it’s becoming more and more difficult to mine - without spending a lot of money upfront - it’s not impossible to turn a good profit if you can afford the hardware.bitcoin 2020 TECHNICAL WEAKNESS: TIME DELAY IN CONFIRMATIONbitcoin synchronization fast bitcoin bitcoin cnbc Iterative development allows software to spread rapidly and benefit from real-world reactions from users. Programs released early and improved often become successful long before 'better' versions written in the MIT approach have a chance to be deployed. With two seminal papers in 1981 and 1982, the concept of 'first-mover advantage' emerged in the software industry around the same time that Gabriel was formalizing his ideas about why, in networked software, 'worse is better.' Some miners pool resources, sharing their processing power over a network to split the reward equally, according to the amount of work they contributed to the probability of finding a block. A 'share' is awarded to members of the mining pool who present a valid partial proof-of-work.Now for the trickier problem: keeping the ledger secure.conference bitcoin bitcoin доходность reddit ethereum bitcoin paper халява bitcoin bitcoin машины hd7850 monero forecast bitcoin bitcoin зарегистрироваться hashrate bitcoin api bitcoin bitcoin eu bitcoin euro bitcoin payment foto bitcoin Bitcoin is a digital asset designed to work in peer-to-peer transactions as a currency. Bitcoins have three qualities useful in a currency, according to The Economist in January 2015: they are 'hard to earn, limited in supply and easy to verify.' Per some researchers, as of 2015, bitcoin functions more as a payment system than as a currency.ico bitcoin майнер bitcoin ultimate bitcoin miner monero

When the fourth year approaches, the Bitcoin reward will go down to 6.25 Bitcoins, and miners also get the sum of all the transaction fees for a particular block.demo bitcoin bitcoin китай заработок bitcoin bitcoin frog rise cryptocurrency и bitcoin

The work of securing digital relationships is implicit — supplied by the elegant, simple, yet robust network architecture of blockchain technology itself.If the peers of the network disagree about only one single, minor balance, everything is broken. They need an absolute consensus. Usually, you take, again, a central authority to declare the correct state of balances. But how can you achieve consensus without a central authority?boxbit bitcoin iphone tether mastercard bitcoin доходность bitcoin bitcoin tm forum bitcoin bitcoin code bitcoin services bitcoin machines bitcoin фарминг loan bitcoin bitcoin bat payeer bitcoin rx580 monero bitcoin баланс ethereum обвал

This term is an amalgamation of Segregated, meaning 'to separate,' and Witness, which refers to 'signatures on a bitcoin transaction.' Segregated Witness, then, means to separate transaction signatures from a block — and attach them as an extended block. While adding a single program to the bitcoin protocol may not seem like much in the way of a solution, signature data has been estimated to account for up to 65% of the data processed in each block of transactions.bitcoin cost котировки ethereum

With computer systems typically selling with 2GB of RAM as of 2008, and Moore’s Law predicting current growth of 1.2GB per year, storage should not be a problem even if the block headers must be kept in memory.bitcoin koshelek apk tether decred ethereum abi ethereum bitcoin farm monero биржи bitcoin roulette bitcoin debian bitcoin pdf обновление ethereum ethereum block
