Sei Network Improves Blockchain Efficiency by Caching Block Hashes

Sei Network has implemented a new feature that stores the last 256 parent block hashes in its blockchain system. This data is maintained in a sliding ring buffer, which is regularly pruned to remove the oldest entries. The system then serves block hash requests from this cache, with an additional local memory cache to speed up access. When a requested block hash is not in the cache, the system falls back to retrieving historical information from the staking data. This change aims to improve the speed and reliability of blockchain operations, especially for applications that frequently query block hashes. The update involves minimal disruption but requires users and developers to be aware of the new caching mechanism for optimal performance. Overall, this enhancement is expected to make the Sei Network more efficient and responsive for its users.
