Overload refers to a situation where a blockchain network becomes congested due to a high volume of transactions. When too many transactions are submitted simultaneously, the network may struggle to process them efficiently, leading to delays and increased fees.During overload, users experience longer waiting times for their transactions to be confirmed. This often results in higher transaction fees as users compete to prioritize their transactions. Miners or validators typically choose transactions with higher fees, which can leave lower-fee transactions delayed.Overload can impact the overall user experience and undermine the intended advantages of speed and low cost that many cryptocurrencies aim to provide. Some networks implement scaling solutions, such as increasing block size or using layer-2 technologies, to manage this issue. Nevertheless, overload remains a challenge, particularly during periods of high demand or significant market activity.
