Security Issues and Prevention in Web3

Web3 builds a decentralized online world based on blockchain technology and is known for its high security.

However, the blockchain is also a network constructed of code, and there are inevitably some loopholes in it, which makes its security not so absolute.The web2 network we use now also has many security holes, but in reality, most people will not be attacked by hackers etc. when using the Internet.This is because in many cases, attackers spend a lot of energy on attacking users with little "benefits". From this point of view, we should probably thank Web2 for not unlocking the value potential of data.

In Web3, digital content is transformed into digital assets, from which attackers can obtain large amounts of money.From the reports of many blockchain security incidents, we can find that the attacked blockchain often loses millions or tens of millions of dollars in funds, and even hundreds of millions of lost security incidents often occur.In the face of this huge benefit, it is worthwhile for hackers to spend a lot of energy to find loopholes in the blockchain and break it.

One of the great features of Web3 is letting users take charge of their own data and accounts.This also creates some new problems, which is that we need to learn how to manage our own encrypted wallets, private keys, etc.Although Web2 has been criticized by many people for relying on the centralized management method of a certain enterprise or organization to keep data and privacy out of control, it is undeniable that the security protection capabilities of some credible enterprises and authoritative organizations are also very good.High.For example, in the banking system, it is very rare for the user's account to be compromised by hackers, resulting in the loss of funds.

In Web3, users are responsible for the security of their own accounts, and many people lack security awareness, which makes a large number of airdrop scams, phishing and other behaviors also exist in Web3.

As an emerging field, Web3 currently faces many challenges.

Many users and institutions lack effective education and awareness when entering Web3, which makes a huge difference in the technology and security protection adopted in the construction process of Web3.This difference results in many Web3 projects appearing safe to users or project parties, but likely to appear to attackers as an unlocked door.

In addition, with the expansion of the blockchain ecosystem, many attackers destroy the blockchain ecosystem through some lurking malicious nodes.Therefore, securing and managing nodes in the blockchain in a scalable manner has also become a major challenge for the project side.

Some of the technologies used in the blockchain system are very complex, and developers must be able to understand it very clearly, which is also a very noteworthy point for developers.challenge.At the same time, blockchain also requires developers to be able to ensure the correctness of their application design.If these two challenges are not successfully addressed, it is easy for hackers who know it better to find vulnerabilities, and attackers can view the system and program source code at any time.
