The “transaction failure” faced by the Solana network is different from typical transaction failures in general blockchain networks. Normally, transaction failures occur because “the transaction has been processed by validators but failed due to on-chain status.” However, according to the developer cygaar, the current issue faced by Solana is that there are too many transactions on the network, causing nodes to be overwhelmed and unable to process every submitted transaction. As a result, some transactions are discarded, and only a small portion of transactions can be successfully processed. Furthermore, in order to maximize the chances of their transactions being processed, certain bots are sending a large number of transactions to the network, resulting in a vicious cycle of network congestion.
