Durable Nonce

We need to pack a recent blockhash into our tx. If the blockhash is expired, our tx will be rejected. (aprox. 2 min). If you want to get rid of it, you can use durable nonce. Durable nonce has no valid time.

Mechanism

You will need to create a nonce account previously. After you created, there is a nonce will store in the account. Then we can trigger this mechanism by

1. use the nonce as a recent blockhash
2. put nonce advance in the first instruciton in this tx

Here I seperate to 3 step to guide to use it.

• create nonce account
• fetch nonce account info
• use nonce
