How can Blockchain change our lives in the future?
What is Blockchain? Why is Blockchain safe? do I and Blockchain work? I tried to tell you blockchain through the eyes of a software developer.
What is the purpose of Blockchain?Let's briefly recall what it does:
Blockchain is a database in which users are anonymous, data is stored in a distributed format on all users' computers, and you cannot change any previous information because data blocks are linked together.
Because the data is not in a central database, it provides advantages that there is no risk of loss, no chance of being changed. Because the owner of the data is anonymous, it prevents you from being recognized and your assets are known.
What has been done so far?
In fact, what we're going to talk about here, in general, is the Ethereum network, a software development network. Ethereum is a platform for developing applications with a software language called Solidity.
With the Don't sell pixels application on the page, the area in the pixel field you purchased by giving Ether is yours forever! Or you can create a royal line in the Ethereum network and ascend the throne for a while. You can keep the message you want to leave to the world forever by writing it to Blockchain, or you can have a photo that you want to keep forever.
The examples I mentioned above, and many of them, are actually developed and stopped applications. The application may be prepared for developers to better understand the concept of blockchain. But these models, which do not have complex business structures, allow us to easily observe how the blockchain cannot be changed. For example, a message is written in a block, your picture, your place in the royal line, or the pixels you buy on the screen cannot be deleted by someone else, they will live as long as the block in which they are written.
Some more useful examples:
There are many different ways to register a domain name today. But isn't it the best way to register a blockchain domain and keep it forever, and then easily transfer it to someone else? The application called PeerName works on this concept. The domain you received for Ethereum written to the Ethereum network and it is no longer possible to change this ownership to anyone else. Application developers have stated that extensions such as .eth and .bit are not currently supported by ICANN, but believe they will work with different browsers, different interfaces in the future.
UJO writes to Ethereum about the music purchased by the audience. Thus, the artist sees the figures written on the blockchain for his purchased or listened music, and even without the occasional intermediary music company, he can deliver the goods to the end user and earn money.
And the ones I love the most are marriage contracts. With your Ethereum wallet, you can tell the entire blockchain that you are married by pointing to another Ethereum wallet. I've seen various practices in this regard. EtherLovers is another attempt to announce your love to the entire Ethereum network.
Of course, let us state that these applications are conceptual and not yet fully operational.
What can we do with Blockchain?
While the above examples are always on the Ethereum network, we can develop applications using other Blockchain infrastructures, and we can also use Ethereum to connect only to computers that we allow. So the examples are from the Ethereum, but we need to think about what we can do next in Blockchain.
I think many of our structures are now at a level that can pass to Blockchain. For example, marriage; information made by two persons and processed by a wedding officer. If we consider this on the blockchain, the two citizens can make their agreements with the state-assigned blockchain wallets on the blockchain without an officer in between. Thus, people will be able to see the information of the person they are married to, whether they are married before, when they get divorced, after they learn their wallet address. Please note that copies of this database will not be possible, as this database can be found on anyone's computer.
Another institution that can be easily added to Blockchain is the Land Registry and Cadastre. As a result, the land parcel you own is delivered to you with a document prepared in your name and placed in the documents of the Land Registry Cadastre. This can be done simply by writing the relevant parcel on your blockchain wallet. So you tell 80 million that that parcel is yours and that no one can change it unless you want it.
Notary operations can also be solved with Blockchain in the future. For example, in a car sale transaction, the notary public prepares and confirms a sales document and after this time the car changes hands. Likewise, two people with wallets issued by a government agency can write the license plate of the car to be sold on the blockchain and expect the notary to dig it. That is, from a notary seal and a signed approval process, a block written like a miner can be transformed into an approver.
Voting can be prevented by repeating votes by writing to the blockchain with a wallet owned by the user, as well as making the counting of votes healthy and fast. It can also lead to more frequent elections and consultation with more people, increasing the number of valid votes and participation.
So why do we need this?
First of all, there is no possibility to change the transaction movements. It may allow faster transfer of information between them. The processing time will be accelerated, and in some cases, the certifying authority may reduce the costs and thus reduce costs to complete the transaction. Blockchain technology can reduce costs and increase processing speed.
