The hottest topic in the beginning of the new year is the blockchain, but there are still many people who have doubts about their safety and risks. How about the security of the blockchain? What are the blockchain risks ? The following decoration home decoration network Xiaobian will give you an answer one by one, I hope everyone can help after reading.
What about the security of the blockchain?
First, the blockchain is a distributed database technology. Distributed technology mainly refers to the storage architecture. The distributed architecture adopted by the blockchain not only stores the book data on each node, but each node must contain the data of the entire book. This thorough distributed architecture brings a high level of security, and no one can destroy all the nodes at the same time.
Second, blockchain technology can achieve tamper resistance through “blocks†and “chainsâ€. The blockchain stores the data unit as a block. When each block is generated, it must contain the unique "feature value" of the previous block ( which can be regarded as the ID of the block ) . Each block is strictly generated. The order of time is lined up to form a "chain."
Safety is a major feature of blockchain technology. However, from the perspective of privacy protection, the blockchain emphasizes openness and transparency. Any node has the right to operate according to the consensus algorithm, so it is not suitable for scenarios that need to protect data privacy.
What are the blockchain risks?
1. Technical risk: If the launch of Ethereum was once a breeze, but because it is a digital currency with smart contracts, there is a risk of hacking due to possible loopholes in smart contracts. THE DAO, the largest crowdfunding project in Ethereum, was hacked and lost more than $60 million.
2. Legal risks: the legality of digital currency issuance, the right of notarization, and the legality of proof, including the legality of smart contracts, digital bills, accounting clearing, and equity crowdfunding, currently in China and other countries in the world. It is still a blank in law.
