This would be not only extremely expensive but also likely fruitless. Doing such a thing would not go unnoticed, as network members would see such drastic alterations to the blockchain. The network members would then hard fork off to a new version of the chain that has not been affected. This would cause the attacked version of the token to plummet in value, making the attack ultimately pointless, as the bad actor has control of a worthless asset.
The same would occur if the bad actor were to attack the new fork of Bitcoin. It is built this way so that taking part in the network is far more economically incentivized than attacking it. Bitcoin vs. Blockchain Blockchain technology was first outlined in by Stuart Haber and W. Scott Stornetta, two researchers who wanted to implement a system where document timestamps could not be tampered with.
The Bitcoin protocol is built on a blockchain. As discussed above, this could be in the form of transactions, votes in an election, product inventories, state identifications, deeds to homes, and much more. Currently, tens of thousands of projects are looking to implement blockchains in a variety of ways to help society other than just recording transactions—for example, as a way to vote securely in democratic elections.
For example, a voting system could work such that each citizen of a country would be issued a single cryptocurrency or token. Each candidate would then be given a specific wallet address, and the voters would send their token or crypto to the address of whichever candidate for whom they wish to vote.
The transparent and traceable nature of blockchain would eliminate both the need for human vote counting and the ability of bad actors to tamper with physical ballots. Blockchain vs. Banks Blockchains have been heralded as being a disruptive force to the finance sector, and especially with the functions of payments and banking.
However, banks and decentralized blockchains are vastly different. How Are Blockchains Used? Today, there are more than 10, other cryptocurrency systems running on blockchain. But it turns out that blockchain is actually a reliable way of storing data about other types of transactions as well.
For example, IBM has created its Food Trust blockchain to trace the journey that food products take to get to their locations. Why do this? The food industry has seen countless outbreaks of E. In the past, it has taken weeks to find the source of these outbreaks or the cause of sickness from what people are eating. If a food is found to be contaminated, then it can be traced all the way back through each stop to its origin.
Not only that, but these companies can also now see everything else it may have come in contact with, allowing the identification of the problem to occur far sooner and potentially saving lives. This is one example of blockchain in practice, but there are many other forms of blockchain implementation. Banking and Finance Perhaps no industry stands to benefit from integrating blockchain into its business operations more than banking.
Financial institutions only operate during business hours, usually five days a week. That means if you try to deposit a check on Friday at 6 p. Even if you do make your deposit during business hours, the transaction can still take one to three days to verify due to the sheer volume of transactions that banks need to settle.
Blockchain, on the other hand, never sleeps. By integrating blockchain into banks, consumers can see their transactions processed in as little as 10 minutes—basically the time it takes to add a block to the blockchain, regardless of holidays or the time of day or week.
With blockchain, banks also have the opportunity to exchange funds between institutions more quickly and securely. In the stock trading business, for example, the settlement and clearing process can take up to three days or longer, if trading internationally , meaning that the money and shares are frozen for that period of time.
Given the size of the sums involved, even the few days that the money is in transit can carry significant costs and risks for banks. Currency Blockchain forms the bedrock for cryptocurrencies like Bitcoin. The U. In , several failing banks were bailed out—partially using taxpayer money. These are the worries out of which Bitcoin was first conceived and developed. By spreading its operations across a network of computers, blockchain allows Bitcoin and other cryptocurrencies to operate without the need for a central authority.
This not only reduces risk but also eliminates many of the processing and transaction fees. It can also give those in countries with unstable currencies or financial infrastructures a more stable currency with more applications and a wider network of individuals and institutions with whom they can do business, both domestically and internationally. Using cryptocurrency wallets for savings accounts or as a means of payment is especially profound for those who have no state identification. Some countries may be war-torn or have governments that lack any real infrastructure to provide identification.
Citizens of such countries may not have access to savings or brokerage accounts—and, therefore, no way to safely store wealth. When a medical record is generated and signed, it can be written into the blockchain, which provides patients with the proof and confidence that the record cannot be changed. These personal health records could be encoded and stored on the blockchain with a private key, so that they are only accessible by certain individuals, thereby ensuring privacy. In the case of a property dispute, claims to the property must be reconciled with the public index.
This process is not just costly and time-consuming—it is also prone to human error, where each inaccuracy makes tracking property ownership less efficient. Blockchain has the potential to eliminate the need for scanning documents and tracking down physical files in a local recording office. If property ownership is stored and verified on the blockchain, owners can trust that their deed is accurate and permanently recorded. If a group of people living in such an area is able to leverage blockchain, then transparent and clear time lines of property ownership could be established.
Smart Contracts A smart contract is a computer code that can be built into the blockchain to facilitate, verify, or negotiate a contract agreement. Smart contracts operate under a set of conditions to which users agree. When those conditions are met, the terms of the agreement are automatically carried out.
Say, for example, that a potential tenant would like to lease an apartment using a smart contract. The landlord agrees to give the tenant the door code to the apartment as soon as the tenant pays the security deposit. Both the tenant and the landlord would send their respective portions of the deal to the smart contract, which would hold onto and automatically exchange the door code for the security deposit on the date when the lease begins. This would eliminate the fees and processes typically associated with the use of a notary, a third-party mediator, or attorneys.
Supply Chains As in the IBM Food Trust example, suppliers can use blockchain to record the origins of materials that they have purchased. Voting As mentioned above, blockchain could be used to facilitate a modern voting system. Voting with blockchain carries the potential to eliminate election fraud and boost voter turnout, as was tested in the November midterm elections in West Virginia. Using blockchain in this way would make votes nearly impossible to tamper with.
The blockchain protocol would also maintain transparency in the electoral process, reducing the personnel needed to conduct an election and providing officials with nearly instant results. This would eliminate the need for recounts or any real concern that fraud might threaten the election. From greater user privacy and heightened security to lower processing fees and fewer errors, blockchain technology may very well see applications beyond those outlined above.
But there are also some disadvantages. Pros Improved accuracy by removing human involvement in verification Cost reductions by eliminating third-party verification Decentralization makes it harder to tamper with Transactions are secure, private, and efficient Transparent technology Provides a banking alternative and a way to secure personal information for citizens of countries with unstable or underdeveloped governments Cons Significant technology cost associated with mining bitcoin Low transactions per second History of use in illicit activities, such as on the dark web Regulation varies by jurisdiction and remains uncertain Data storage limitations Benefits of Blockchains Accuracy of the Chain Transactions on the blockchain network are approved by a network of thousands of computers.
This removes almost all human involvement in the verification process, resulting in less human error and an accurate record of information. Even if a computer on the network were to make a computational mistake, the error would only be made to one copy of the blockchain.
Cost Reductions Typically, consumers pay a bank to verify a transaction, a notary to sign a document, or a minister to perform a marriage. Blockchain eliminates the need for third-party verification—and, with it, their associated costs. For example, business owners incur a small fee whenever they accept payments using credit cards, because banks and payment-processing companies have to process those transactions. Bitcoin, on the other hand, does not have a central authority and has limited transaction fees.
Decentralization Blockchain does not store any of its information in a central location. Instead, the blockchain is copied and spread across a network of computers. Whenever a new block is added to the blockchain, every computer on the network updates its blockchain to reflect the change. By spreading that information across a network, rather than storing it in one central database, blockchain becomes more difficult to tamper with. If a copy of the blockchain fell into the hands of a hacker, only a single copy of the information, rather than the entire network, would be compromised.
Efficient Transactions Transactions placed through a central authority can take up to a few days to settle. If you attempt to deposit a check on Friday evening, for example, you may not actually see funds in your account until Monday morning.
Whereas financial institutions operate during business hours, usually five days a week, blockchain is working 24 hours a day, seven days a week, and days a year. Transactions can be completed in as little as 10 minutes and can be considered secure after just a few hours.
This is particularly useful for cross-border trades, which usually take much longer because of time zone issues and the fact that all parties must confirm payment processing. Although users can access details about transactions, they cannot access identifying information about the users making those transactions. It is a common misperception that blockchain networks like bitcoin are anonymous, when in fact they are only confidential.
When a user makes a public transaction, their unique code—called a public key, as mentioned earlier—is recorded on the blockchain. Their personal information is not. Secure Transactions Once a transaction is recorded, its authenticity must be verified by the blockchain network. Thousands of computers on the blockchain rush to confirm that the details of the purchase are correct.
After a computer has validated the transaction, it is added to the blockchain block. Each block on the blockchain contains its own unique hash, along with the unique hash of the block before it. This discrepancy makes it extremely difficult for information on the blockchain to be changed without notice. Transparency Most blockchains are entirely open-source software.
This means that anyone and everyone can view its code. This gives auditors the ability to review cryptocurrencies like Bitcoin for security. Because of this, anyone can suggest changes or upgrades to the system. If a majority of the network users agree that the new version of the code with the upgrade is sound and worthwhile, then Bitcoin can be updated. Banking the Unbanked Perhaps the most profound facet of blockchain and Bitcoin is the ability for anyone, regardless of ethnicity, gender, or cultural background, to use it.
According to The World Bank, an estimated 1. Nearly all of these individuals live in developing countries, where the economy is in its infancy and entirely dependent on cash. These people often earn a little money that is paid in physical cash. They then need to store this physical cash in hidden locations in their homes or other places of living, leaving them subject to robbery or unnecessary violence.
Keys to a bitcoin wallet can be stored on a piece of paper, a cheap cell phone, or even memorized if necessary. For most people, it is likely that these options are more easily hidden than a small pile of cash under a mattress. Blockchains of the future are also looking for solutions to not only be a unit of account for wealth storage but also to store medical records, property rights, and a variety of other legal contracts.
Drawbacks of Blockchains Technology Cost Although blockchain can save users money on transaction fees, the technology is far from free. While some business owners still have apprehensions about accepting cryptocurrencies due to its volatile nature, there are others unable to do so due to lack of proper tools. BlockPay intends to change this by offering a simple, easy to use, and free platform that enables merchants and businesses to accept cryptocurrency payments.
