The main limitations include: 1. The complexity of blockchain, which makes the demand for understanding and using blockchain technology relatively high, limiting its application in some fields; 2. The risk of 51% attacks, where if attackers control more than 50% of the computing power in the blockchain network, they may tamper with data or prevent transactions; 3. High energy consumption, the operation of the blockchain network requires a large amount of computing resources and electricity, which is a challenge in situations with limited environment and resources; 4.  Scalability, the performance of blockchain technology in handling a large number of transactions may be affected; 5. Lack of regulation and oversight."}]}],"pr":"02453550a40b176b373ff07cbe8186654262308f91a8573b7736835a9830c00d"}
