This process consumes a large amount of computing resources, which may lead to slower transaction confirmation speed. However, POW mechanism has higher security, helping to prevent fraud behaviors such as double-spending attacks."}]}],"pr":"951b24b472994add4c93599b19ec19e90cb26e0a693108c9714e34910038f300"}
