Blockchain technology has many benefits, including enhanced security, better transparency, instant traceability, and higher efficiency and speed. However, even the largest blockchain fans cannot deny this -this technology has its defects, and they have caused problems in the past. But so far, the team behind the large blockchain that encounters the problem has taken action and repaired the loopholes. In this article, we will explore issues related to blockchain patches.

What is blockchain?

The blockchain is a distributed database or classification of the computer network nodes. As a database, the blockchain stores information in a digital format. The blockchain is famous for its key role in cryptocurrency systems such as Bitcoin to maintain safe and decentralized transaction records. The innovation of the blockchain is that it guarantees the preservation and security of the data records, and has trusted without the need of trusted third parties.

A key difference between a typical database and blockchain is the structure of the data. The blockchain collects information in the form of a group, called blocks, saving information sets. The block has a certain storage capacity, and when the filling is closed and linked to the previously filled block, it forms a data chain called the blockchain. All new information after the new block is compiled into a newly formed block. Once filled, the block will also be added to the chain.

The database is usually structured into a table, while the blockchain, as the name suggests, structures its data into blocks (blocks) stringed together. When implementing it in a decentralized manner, this data structure inherently forms an irreversible data timeline. When a block is filled, it is fixed and becomes part of this timeline. Each block in the chain is given an accurate time stamp when it is added to the chain.

Key points

Blockchain is a shared database that is different from typical databases in the way of storage information; the blockchain stores data in the block, and then these block links are linked together by cryptography.

As the new data arrives, it is input into a new block. Once the block is full of data, it will link to the previous block, which makes the data link together in the order of time.

Different types of information can be stored on the blockchain, but the most common purpose so far is the classification account for transactions.

As far as Bitcoin is concerned, the blockchain is used in a decentralized manner, so no individual or group has control -instead, all users retain their control together.

The decentralized blockchain is immutable, which means that the input data is irreversible. For Bitcoin, this means that the transaction will be permanently recorded and anyone can view anyone.

Is the blockchain safe?

Blockchain technology realizes decentralized security and trust in various ways. First of all, the new block always stores linearly in the order of time. In other words, they are always added to the "end" of the blockchain. After adding the block to the end of the blockchain, it is extremely difficult to return and change the content of the block, unless most people in the network have reached a consensus. That's because each block contains its own hash values, the hash value of its previous block, and the timestamp mentioned earlier. The hash code is created by a mathematical function, which converts digital information into a string of numbers and letters. If the information is edited in any way, the hash code will be changed.

Assuming a hacker also runs a node on the blockchain network, he wants to change the blockchain and steal cryptocurrencies from others. If they want to change their single copy, it will no longer be consistent with other people's copies. When others are against their copy, they will see that this copy stands out, and the hacker chain version will be considered illegal and abandoned.

In order to successfully perform such hackers, hackers need to control and change 51% or more blockchain copies at the same time, so that their new copies can become most copies, thereby becoming an agreed chain. Such attacks also require a lot of funds and resources, because they need to redo all the pieces because they now have different timestamps and hash codes.

Due to the scale and growth rate of many cryptocurrency networks, the cost of achieving this feat may not be overcome. This will not only be very expensive, but also may have no results. Doing such things will not be ignored, because network members will see such a fierce change in the blockchain. Then, the network member puts a new version of the hard fork to the unsightful chain. This will cause the attacked version of the tokens to plummet, making the attack ultimately meaningless because the bad guys control worthless assets. If the bad guys want to attack the new fork of Bitcoin, the same situation will happen. It is built in this way, so participating in the network is more economical than attacking the network.

What can cause blockchain problem?

Theoretically, this technology sounds very utopian, right? A safe, transparent and peaceful data storage and transmission environment. But it is not without flaws, some can be tolerated, and some cannot be avoided. Some critics are now pointed out, such as scalability, energy consumption, lack of general standards, etc. But we are talking about what is the blockchain patch here. This is why we will pay attention to the elephant in the room -blockchain can be attacked by hackers. Let's see how.

51%attack

In order to make the blockchain play, people on the Internet need to verify transactions to ensure its authenticity. This is done by many people to protect the process and eliminate the possibility of someone manipulating it. However, if someone wants to access more than half of the network and accurately speaking, 51% or more, then they may bring problems to the entire blockchain, such as creating the second version of the blockchain or double flower cryptocurrency. This is more likely to occur on a smaller blockchain, because the larger blockchain is more difficult to obtain this control.

Lack of proper security

Most of the blockchain -related hacker attacks occur on the encryption exchange exchange. This is due to the incomplete security measures of the exchange, which causes malicious attacks to easily destroy its data and cause network errors or even steal user funds.

Initial error

If the network is too complicated and the developer misses the failure or makes the error pass by the invisible situation, then the blockchain problem may occur from the beginning. This may become the goal of hackers in the future and use it as the weakness of attacking the blockchain. Smart contracts (running on the blockchain) also observed similar situations.

These are some problems that the blockchain may encounter. For certain network problems, possible solutions are patch. But what exactly is the blockchain patch? We will eventually find its answer and what its purpose is.

What is blockchain patch and its role

What is the simple answer of the blockchain patch may be:

Blockchain patch is a software change, which aims to correct the tiny abnormality or defects in the blockchain network, or provide tiny performance improvements without changing the basic design, structure or function of the network.

These patchs usually have numbers to indicate the modification of the blockchain version.

As you can see, the answer to what is blockchain patch is very straightforward -it is a solution and repair on the problems that occur on the network. Not all blockchain problems can be solved by patch. Here, "Chuangya Paste Can't Fix the Pole Pole" is completely applicable -you cannot solve all problems through a small software upgrade. For example, if your exchange is hacked and your client lost funds, you cannot publish blockchain psychology to let them return. This is not its working principle.

The role of blockchain patching is to ensure that errors will not happen again. If it is applied in time, patch can enhance the security of the blockchain and prevent further damage to the network, while developers strive to further enhance their security. The blockchain can be packed regularly to repair slight inconvenience. However, there are also situations where the blockchain patch is applied after the problem has occurred. We will discuss in the next section.

What is a blockchain patch: an example

As we have explained what is the blockchain patch and its usage method, we need to figure out something -it may be helpful, but the premise is to complete on time. We said that not to remind developers (they should) monitor their blockchain well, but because history gave us this lesson. What is an example of the patching of the patching of the Qi school, and why you should apply them in time, otherwise there may be more problems. Let's check it.

Ethereum Puppet School testing the patching problem

The history of Parity/Ethereum can be said to be a real blockchain legend. But before that, let's explain what every one is:

So what is the problem? Well, there are a lot of. Starting from the Parity wallet hacker attack in 2017, someone found a loophole on the Parity wallet and could steal 150K ETH (about 30 million US dollars). However, things did not really stop.

The problem of Parity and Ethereum is that there are many wrong cases, which is normal, and all technologies have their defects. Developers work hard to find solutions, but the main problem here is that they are unhappy. The purpose of the blockchain patch is to repair the errors as soon as possible, so that people will not get their Ether or anything else, and to be stolen, which means that time is very important. Reports that Parity has not implemented its blockchain patches in multiple occasions.

What is the avoided blockchain patching method?

After understanding what is the blockchain patch, you may be aware that it can be regarded as two things: a frequent maintenance program and developers repair a way to repair its network after there is vulnerability.

Although the first one is very common, because each technology needs to be repaired during the work process, the second one should be paid specially. For serious situations, the avoided blockchain patching method is to be closely monitored by the network. You can even use blockchain analysis tools to help identify any potential risks.

However, the most important way to avoid large vulnerabilities patch is to update. Update the network, update when publishing blockchain patch, and always update to the latest version. This is suitable for developers of each ordinary user and blockchain. If you are looking for "What is the blockchain patching method to avoid?" This is through continuous updating and upgrading your network.

How to help enterprises in the blockchain patch?

Blockchain patch is a software update, and enterprises can use it to add or update functions on the blockchain network. This can include new applications or services, updated nodes or smart contracts, or fixes wrong. By using the blockchain patch, enterprises can maintain its latest and secure without having to turn off the entire system and began to be rebuilt from scratch.

The future of blockchain technology

If we look forward to the future of blockchain technology, we are likely to see many different applications of this technology. Some of these applications may include:

-Glit Global Digital Assets Registration

-The ability to transaction safely and transparently

-Colon the Internet that is safe and decentralized

All these applications may change our way of life and work, and they have just begun to be explored. With the continuous development of blockchain technology, we can look forward to seeing more exciting applications.

The above content introduces the definition and case of blockchain patch. Because blockchain technology is transparent, this means that everyone can see transactions on the Internet, which makes it difficult for anyone to hide their activities. This is an important feature because it allows unwanted exchange between parties. In addition, the security of the blockchain is also worth noting. It needs to be maintained and repaired frequently, patch and apply it in a timely manner. Do not wait until someone cracked your blockchain before trying to solve the problem.
