Let’s chat about security issues related to blockchain and cryptocurrencies

Both companies and individuals should take the time to pay attention to the security issues related to blockchain and cryptocurrencies, after all, risk control is the first priority. Otherwise, if you are busy mining, speculating in coins, and bottom-hunting, if you accidentally catch fire in the backyard, you will be "ransacked". What you have worked so hard to earn will be harvested, and even bankrupt.

This article does not intend to confuse the concepts. Unless otherwise stated, the Bitcoin, digital encrypted assets, and cryptocurrencies involved in this article share the same connotation.

Finally, it will also focus on demonstrating the practice of enterprise security technology: how to protect the security of enterprise computing resources and personal encrypted currency assets with the help of cloud security products on the Alibaba Cloud platform.

1.2 Wallet Risk

Almost all mainstream digital currencies have corresponding digital asset management tools - wallets. Taking Bitcoin BTC as an example, there are dozens of mainstream wallets currently supporting BTC, and they are also divided into software and hardware, online and offline, PC and mobile.

Due to issues such as historical data, network synchronization and inconvenience, it is very cumbersome and unrealistic for individuals to run and maintain a huge BTC client to manage assets. More and more digital currency asset management manufacturers have developed wallet applications or hardware.
