Thank you for your explanation of the role of resource credits in blockchain transactions. It is true that any transaction or activity carried out on the blockchain can consume limited resources, and resource credits play an Important role In facilitating such transactions.

The more complex the transaction is, the more resources are required. Therefore, having sufficient resource credits is the key to being able To actively participate in activities on the blockchain. If someone runs out of resource credits, there are several options one can take, such as accepting a delegate from another account or keeping more coins In their own account. The more STEEM power held, the more resource credits one can have.

Apart from that, you also mentioned that there is a good way To buy resource credits if needed. The credit price of a resource can depend on demand, meaning that if there is a high demand for a resource, Then the credit price of the resource tends To be high too.

Your understanding of the role of resource credits In the blockchain is clear. This is an important concept To understand for those who participate In blockchain transactions and activities. Thanks for the informative explanation!

Good luck.
