DeprecatedThe getRecentBlockhashmethod is deprecated starting from the Solana client v1.9. This method only works on older outdated clients v1.8 and below.For the currently supported and up-to-date method, see getLatestBlockhash .
The Solana getRecentBlockhash method returns a recent block hash from the ledger, and a fee schedule that can be used to compute the cost of submitting a transaction using it. This method is crucial for transaction construction and submission in Solana. The returned blockhash is used to indicate when a transaction was constructed, which is important for security reasons. The fee calculator provides information about the current network fees.
