The Relationship Between Blockchain Technology and Bitcoin | TechBullion

As mentioned above, bitcoin transactions are recorded and stored in a public ledger. Each transaction is recorded on the ledger as a block. A series of transactions form a blockchain. Notably, the term blockchain is also used to refer to the technology itself. While blockchain is the series of bitcoin transactions on a public ledger, blockchain technology is the technology that is used to record the transactions.

While bitcoin is the digital asset currency , blockchain is the technology that bitcoin is built on. Therefore, bitcoin is dependent on blockchain technology. Without blockchain, bitcoin would not be valuable because there would be no secure method of transacting in it. Blockchain provides a verifiable database ensuring that all purported transfers are actually transfers.

As a result, you are protected from double spending and fraud. The relationship between blockchain and bitcoin is of great significance.

Through blockchain, the distributed computers recording and verifying a transaction must agree that the transaction is valid before a new block can be added to the chain. This presents a level of security and protection that has not been witnessed before. No single computer can alter the history of the chain. The trust that is usually given to central institutions such as banks to keep accurate records will eventually be replaced with a consensus-based model.

It is suggested that although current discourse about blockchain has been limited to its applicability in the financial sector, it will in future be used in record keeping, property deeds, contracts, and shipping information. It is for this reason that many commentators have labelled blockchain a disruptive technology.

Trending Stories In contrast, a database is designed to house significantly larger amounts of information that can be accessed, filtered, and manipulated quickly and easily by any number of users at once.

Large databases achieve this by housing data on servers that are made of powerful computers. These servers can sometimes be built using hundreds or thousands of computers in order to have the computational power and storage capacity necessary for many users to access the database simultaneously.

While a spreadsheet or database may be accessible to any number of people, it is often owned by a business and managed by an appointed individual that has complete control over how it works and the data within it. So how does a blockchain differ from a database? One key difference between a typical database and a blockchain is the way the data is structured. A blockchain collects information together in groups, also known as blocks, that hold sets of information. A database structures its data into tables whereas a blockchain, like its name implies, structures its data into chunks blocks that are chained together.

This makes it so that all blockchains are databases but not all databases are blockchains. This system also inherently makes an irreversible timeline of data when implemented in a decentralized nature. When a block is filled it is set in stone and becomes a part of this timeline. Each block in the chain is given an exact timestamp when it is added to the chain. For the purpose of understanding blockchain, it is instructive to view it in the context of how it has been implemented by Bitcoin.

Like a database, Bitcoin needs a collection of computers to store its blockchain. For Bitcoin, this blockchain is just a specific type of database that stores every Bitcoin transaction ever made. Imagine that a company owns a server comprised of 10, computers with a database holding all of its client's account information. This company has a warehouse containing all of these computers under one roof and has full control of each of these computers and all the information contained within them.

Similarly, Bitcoin consists of thousands of computers, but each computer or group of computers that hold its blockchain is in a different geographic location and they are all operated by separate individuals or groups of people.

However, private, centralized blockchains, where the computers that make up its network are owned and operated by a single entity, do exist. In a blockchain, each node has a full record of the data that has been stored on the blockchain since its inception. For Bitcoin, the data is the entire history of all Bitcoin transactions. If one node has an error in its data it can use the thousands of other nodes as a reference point to correct itself.

This way, no one node within the network can alter information held within it. This system helps to establish an exact and transparent order of events. This ensures that whatever changes do occur are in the best interests of the majority. Each node has its own copy of the chain that gets updated as fresh blocks are confirmed and added. This means that if you wanted to, you could track Bitcoin wherever it goes. For example, exchanges have been hacked in the past where those who held Bitcoin on the exchange lost everything.

While the hacker may be entirely anonymous, the Bitcoins that they extracted are easily traceable. If the Bitcoins that were stolen in some of these hacks were to be moved or spent somewhere, it would be known. Blockchain technology accounts for the issues of security and trust in several ways.

First, new blocks are always stored linearly and chronologically. After a block has been added to the end of the blockchain, it is very difficult to go back and alter the contents of the block unless the majority reached a consensus to do so. Hash codes are created by a math function that turns digital information into a string of numbers and letters.

If that information is edited in any way, the hash code changes as well. If they were to alter their own single copy, it would no longer align with everyone else's copy.

When everyone else cross-references their copies against each other, they would see this one copy stand out and that hacker's version of the chain would be cast away as illegitimate. Such an attack would also require an immense amount of money and resources as they would need to redo all of the blocks because they would now have different timestamps and hash codes. Not only would this be extremely expensive, but it would also likely be 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 fork off to a new version of the chain that has not been affected.

This would cause the attacked version of Bitcoin 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. The goal of blockchain is to allow digital information to be recorded and distributed, but not edited.

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. The key thing to understand here is that Bitcoin merely uses blockchain as a means to transparently record a ledger of payments, but blockchain can, in theory, be used to immutably record any number of data points.

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, there is a vast variety of blockchain-based projects looking to implement blockchain in ways to help society other than just recording transactions.

One good example is that of blockchain being used as a way to vote 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 whichever candidate's address they wish to vote for.

The transparent and traceable nature of blockchain would eliminate the need for human vote counting as well as the ability of bad actors to tamper with physical ballots.

Banks and decentralized blockchains are vastly different. But it turns out that blockchain is actually a reliable way of storing data about other types of transactions, as well.

Why do this? The food industry has seen countless outbreaks of e Coli, salmonella, listeria, as well as hazardous materials being accidentally introduced to foods. 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, potentially saving lives. This is one example of blockchains in practice, but there are many other forms of blockchain implementation. Perhaps no industry stands to benefit from integrating blockchain into its business operations more than banking. Financial institutions only operate during business hours, 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. 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. Blockchain forms the bedrock for cryptocurrencies like Bitcoin. The U. In , some of the banks that ran out of money 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 they can do business with, 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 riddled with 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, transparent and clear timelines of property ownership could be established. 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 that users agree to. When those conditions are met, the terms of the agreement are automatically carried out.

Say, for example, 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 the lease begins.

This would eliminate the fees and processes typically associated with the use of a notary, third-party mediator, or attornies. As in the IBM Food Trust example, suppliers can use blockchain to record the origins of materials that they have purchased. As reported by Forbes, the food industry is increasingly adopting the use of blockchain to track the path and safety of food throughout the farm-to-user journey.

As mentioned, 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. Provides a banking alternative and way to secure personal information for citizens of countries with unstable or underdeveloped governments. Here are the selling points of blockchain for businesses on the market today in more detail.

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. 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. Bitcoin, on the other hand, does not have a central authority and has limited transaction fees. Blockchain does not store any of its information in a central location.
