IEEE/ICACT20210248 Answer.1

Thanks for replying to question 1. I have a question. You said easy mining and security are less relevant. But as far as i know Easy mining means that the mining difficulty is low, and we believe that this can easily cause mining pool attacks if the difficulty is low in the mining pool of the miner. Also, will the blockchain network not overload due to the creation of Uncle blocks due to redundant mining? Thanks again for your question. If the difficulty level is lowered while the mining cycle is maintained, it may become vulnerable to mining attacks. However, it cannot be concluded that the process of reducing the difficulty level while shortening the mining cycle like Litecoin is vulnerable to mining attacks. Therefore, in this sense, the security of Pyeongtaek Coin, which simultaneously controls the mining cycle and difficulty level, can be maintained similar to those of existing coins. In addition, the mining process of Pyeongtaek Coin does not perform redundant mining because the lightweight transaction does not independently mine the block, and maintains the serialization of block generation through the synchronization process with the heavyweight transaction. Therefore, it does not generate unnecessary additional blocks accordingly, and does not cause excessive overhead compared to the existing blockchain network.
