Hi all cryptoacademy friends, how are you? May you always be given health, and I am here as well.
It's great to be able to join this contest, and if there are errors in this post please correct it and it is very valuable to me.

Blockchain is changing everyone's daily life, what do you think about this issue?

Blockchain is a very advanced and secure technology that has an extraordinary level of security and has a ledger that stores all digital data that is carried out and distributed in a decentralized manner (all can view and read data) to all nodes online, where this storage system contains records linked via cryptography.

Blockchain itself has made all transactions much more transparent so that we can find out whether transactions using this blockchain are fraudulent or not, whether the transaction has violated other laws or not.

Blockchain technology has a high level of security, so it is impossible for hackers to commit fraud because blockchain is also transparent so that it minimizes hackers from hacking the data we have, because blockchain has several important parts in it, such as Data, Hash and Previous Hash tags.

Well, from the explanation above, now I will express my opinion about blockchain that changes life is that it is true that blockchain really changes everyday life for everyone, because this technology is very easy to use and apply because this blockchain system contains all data, time, place , and what types of transactions the users of this system perform. And this technology can be accessed by anyone, anytime, and anywhere via a smartphone, or laptop without having to ask for approval from a third party. This technology can save time, effort and space, for example in;

Bank

Bank is a place to store money where we have to take queue and queue numbers, so we need a lot of time, and also banks will usually ask for some letters and documents, and if they are not complete they will not authorize our transactions, this will use a lot of energy, and for one transaction will take energy, place and time, but by using this blockchain technology, all these problems will be solved.

Culinary

In today's culinary world, technological advances are also needed and adopted to provide convenience for culinary lovers. Like banks and hospitals that use blockchain technology, the culinary world will also get many benefits such as; for suppliers, if they enter data about the type of food, the origin of the food ingredient, so that the food is correct, the restaurant and others will knowing where this food comes from and for consumers to choose their own type of food and also the restaurant he wants to visit. very timely?

There are many more benefits of using blockchain technology for our lives such as the use of blockchain in companies and schools, colleges, police, and also the world of health.

What are the main advantages and disadvantages, in adopting the use of blockchain in everyday life?

After we know how blockchain makes our activities easier, then we will know the main advantages in adopting it in everyday life;

Advantages

Transparent

No one will be able to manipulate the data contained in this technology. Because this blockchain has transparency that is beneficial for all sectors and related agencies because it can be accessed by anyone, anytime and anywhere through their smartphone, laptop, or computer. For example; for an agency, the company will have a large number of transactions, if the transaction is not carried out transparently, then there is a possibility that the transaction has been modified and has invalid history results.

Save time, space and space, and money

The advantage of this technology is that because blockchain technology is in software, wherever, whatever and whenever we can access and make transactions without having to spend a lot of time, place, space and even money because it can be accessed via smartphones and other software.

Better and safer

Because blockchain is a distributed technology in digital ledger so it has high systematic and also blockchain database is Append only, which means it can only be added and there is no command to edit so it is impossible for hackers to do their skills here.

No third party

Blockchain is a decentralized technology or does not require a third party, because all transactions carried out on the blockchain only me and the network work. So that the role of the broker is not needed so that all transactions are faster, less complicated, and free from the potential for human error.

Internal audit

Blockchain also stores all the data that is done, this will make it easier for technology users to find out all the information that occurs before adding new data. Companies that use blockchain technology, every user can know the audit trail of an asset and this can prevent it from corruption and even money laundering.

Trust

Because blockchain stores all data securely and securely, and is transparent, it comes with users' trust in this advanced technology. Trust about all transactions, audited data, everything keeps a history that everyone can know whatever happened with the transaction, thus minimizing the danger and potential bad that will happen.

Apart from having very beneficial uses for us, it turns out that blockchain technology also has disadvantages;

Disadvantages

Blockchain cannot repeat all existing data, meaning that it can only add and cannot subtract.

It takes a long time for a block to be confirmed by making an agreement with the parties on the blockchain network. This depends on the capacity and speed of the blockchain operating system.

It costs a lot of money to make transactions on the blockchain, considering that blockchain is a technology that performs many smart contracts.

If you lose the access key to get the blockchain, then all the data in this technology will all become memories and there is no way to get it back, except by going back to the original point to get the blockchain key.

There is no recovery of transaction funds. If there is a blockchain attack that results in funds disappearing, after the transaction history is released, but not yet on our blockchain, then the funds are lost and impossible to recover, because no personal data is confirmed and where the funds are flowing. This is why, waiting for confirmation of the transactions made will minimize losses.

Discuss the future of blockchain, and how this technology is impacting the world.

It is undeniable that blockchain technology is increasingly recognized and closely related to people's lives. There is no reason to use it, people prefer an efficient and safe way to carry out various transactions in order to minimize existing losses and be transparent and save money, time and space.

As technology is increasingly being developed and used by people today, it is possible that there will be a very big change in operating systems around the world from using traditional paper systems to distributed paper systems from online.

Blockchain in the World Economy

As we have heard and read that international trade is often accompanied by mistakes made by import-exporters, it is unclear, fraudulent, counterfeiting, and also becomes a dirty political tool and has poor security.
Well, by using Blockchain technology. in the input of all information, documentation, and transactions of goods, types of goods, recipients, buyers and origins of the goods, then all parties will know the origin if there is a defect in the goods.

Not only that, cryptocurrency can also be a good solution in processing payments in a single digital international system. This will minimize and even eliminate fraud, embezzlement and of course very safe and fast, save space and time so that it will improve the international trade process and also increase trust between various countries in the world.

Blockchain in government

Today's era relies heavily on technology so that almost all activities are accompanied by technology that is getting smarter and smarter. Blockchain is one of the most intelligent, secure, distributed technologies, and has a high level of efficiency and good security so it does not demand the possibility that any kind of community agency will use this technology as the main alternative in all transactions and documentation.

For example, accessing identity that will use technology is considered very efficient because everyone can prove their identity which is questioned by several states by identifying the information contained in an open-source encrypted ledger which will be more secure and reliable.

Not only that, through the encryption and validation features offered by blockchain technology, the government will gradually divert all data collection processes and all related information in a ledger technology system that will obviously be more secure, transparent, and reliable.

I believe, with the benefits offered by blockchain technology, all existing agencies will use this technology as input for all traces of transactions, data, information, and also as a documentation tool that cannot be manipulated.

Blockchain in voting

As we know that the current voting has drawn criticism from the public because it is suspected of being dishonest and a lot of the data being manipulated so that the results of the votes come out are not in accordance with what is happening in the field. It can be said that currently humans are facing a crisis of confidence in voting, therefore, blockchain is here and is a solution. No manipulation is possible because everything is processed in a decentralized system and has a high level of security so that skewed issues will disappear and people can trust again in their choices and will also provide other benefits such as saving money, space and time.

Blockchain in copyright

As creative actors (writers, painters, singers, and musicians) they want to protect their work from irresponsible parties. They want their work to have copyright and recognition from various parties, blockchain technology is the solution to this problem. Blockchain provides copyright data, copyright information and also everything about their work which is organized in a decentralized system and they can share it with third parties with their permission without having to fear that their work will be counterfeited.

What is your opinion about the implementation of blockchains in the health sector? Has the implementation been positive or negative? Explain a use case.

In health institutions, the use of blockchain has a positive impact, for example, the medical records of patients in hospitals are very complete due to the lack of digitization and also traditional paper which allows it to be lost even if the hospital fires then there is no patient data that can increase usage. In some cases, patients even manipulate data to be able to claim insurance money.

In the world of health, using blockchain technology, hospitals can add patient medical data into a computer network, where the network is interconnected with each other. All disease data, allergy history, types of drugs, precautions, information, all transactions, and all logins made by users will be recorded, stored, and then confirmed by the parties involved without any third party. If at any time the hospital's patient data returns, the hospital can view, access, require and retrieve the patient's data and if you want to update the data that has been updated by the hospital it will be stored without deleting the previous patient data.

Blockchain can also provide convenience, patients can provide electronic health cards to be accessed between where all their involvement and patients, drug prescriptions, and even actions taken to patients are recorded completely and safely. This is where patients and doctors must really fill in the data correctly so that there are no errors in the next action.

In the world of health, counterfeiting of drugs also often occurs and no party is responsible if there are cases of drug poisoning. Blockchain again provides a solution to this case where we can find out the origin of the drug, the drug manufacturer, the history of the drug manufacturer, third party distributors, consumers, so that it will be detected if an error occurs even drug counterfeiters.

Every technology has its drawbacks, even blockchain technology, but the advantages we get are greater so it does not demand the possibility that blockchain will be developed in the healthcare sector, and possibly in other sectors.

Conclusions

Blockchain is a highly advanced and secure technology that has an extraordinary level of security and has a ledger that stores all digital data that is carried out and distributed in a decentralized manner (all can view and read data) to all nodes online, where this storage system contains records. connected via cryptography.

Blockchain technology is growing so that the world has a very big impact. Money, space and time have been saved and blockchain provides a high level of security, which increases trustworthiness, and also audits data that does not eliminate data before it. But we must also be aware of the limitations of the blockchain so that it will minimize the losses that we will get.

Thank you to steemit crypto academy for always providing a place for us to learn blockchain science, hopefully this knowledge can be useful for all of us and can be applied in everyday life.
