Course Introduction:, add the p tag to each paragraph. Bitcoin unconfirmed transfer processing Bitcoin is a decentralized digital currency. Its transactions do not require third-party institutions, but some transactions require network confirmation. Unconfirmed transfers are one of the common problems faced by Bitcoin users. When a Bitcoin user initiates a transfer, the system distributes it to network nodes. The node checks the validity of the transfer and records it in the blockchain after meeting the requirements, which is confirmation. Unconfirmed transfers refer to transfers initiated by users that have not yet been confirmed by network nodes. At this time, the status of the transfer is Unconfirmed, the recipient cannot obtain the currency, and the transfer has not yet been completed. Unconfirmed transfers can occur for a variety of reasons, the most common of which is a busy network. When the network is busy, transactions sent by users will be queued for confirmation, causing the confirmation speed to slow down and therefore not be confirmed.

Course Introduction:The principle of Bitcoin handling fees is similar to the bidding system. When demand is strong, users add higher handling fees to transactions, and miners will include the transaction in the block. Each Bitcoin transaction includes a fee paid to the miners to process the transaction. There is a small handling fee, and miners give priority to transactions with higher handling fees. That is, the higher the handling fee, the higher the possibility that the transaction will be included in the new block. This will also lead to the situation where Bitcoin handling fees are low and are not confirmed.
