Answer

Blockchain-based transaction deferral involves storing a record of a transaction request in the blockchain instead of processing resource-intensive backend tasks immediately. The request can then be processed when resources become available, effectively managing workload fluctuations.

Deferring transaction requests can prevent backend systems from being overloaded, especially during peak demand periods. This approach can also make more efficient use of resources and improve customer experience by preventing potential failures or delays.

A deferred resource group refers to a collection of resources used to store deferred transaction records, including blockchain services and computing resources used to maintain the blockchain.

**Requester category:** Transaction requests from new or unreliable customers are less likely to be deferred than trusted customers with a good track record.

**Backend workload level:** If the backend system is experiencing a high workload, it is more likely to defer transaction requests to prevent overload.

**Transaction attributes:** Certain transaction requests can be determined to be suitable for deferral based on transaction attributes, such as transaction amount, item category, or acceptable shipping delay.

Machine learning can be used to analyze various factors and generate a deferral suitability score to help determine which transaction requests are ideal candidates for deferral. Predictive models can consider factors such as requester history, transaction details, and system performance metrics to make informed deferral decisions.

Low-overhead data stores, such as key-value stores, can be used to store additional transaction descriptors associated with deferred transactions. This approach reduces the burden on the blockchain and allows for the storage of more comprehensive transaction information that can be retrieved later for backend processing.

The public transparency of blockchain technology allows transaction requesters to verify that their requests have been recorded by querying the blockchain. The record can contain encrypted transaction details or hashes, allowing requesters to confirm the existence of their request without revealing sensitive data.

Blockchain "mining" refers to the resource-intensive computational processes responsible for adding new blocks of transaction records to the blockchain. Miners verify transactions, solve cryptographic puzzles, and add blocks to the blockchain, ensuring the integrity and security of the blockchain.

A common approach is to provide external miners with cryptocurrency rewards or "coins" based on their contribution to blockchain maintenance. Alternatively, compensation related to an organization's specific services or goods can be provided based on the number of blocks processed or computing power provided.

Entities outside of the provider network can benefit from blockchain-based transaction deferrals by leveraging metadata generated by the provider network's workload management services, such as client reputation scores. This information can enhance external entities' own transaction deferral decisions, even if their application infrastructure is outside the provider network.
