The “transaction failure” faced by the Solana network is different from the typical transaction failures in other blockchain networks, which are usually due to “transactions being processed by validators but not succeeding due to on-chain state.” However, according to developer cygaar, the current problem faced by Solana is that there are too many transactions on the network, causing nodes to be overwhelmed and unable to handle every submitted transaction. As a result, some transactions are discarded, and only a small portion of transactions can be successfully processed. Additionally, certain bots are sending a large number of transactions to the network in order to maximize the chances of their transactions being processed, further exacerbating the network congestion in a vicious cycle.
