US Patent 12013833 Blockchain-based high-speed data processing device and method thereof

Proposed are a blockchain-based high-speed data processing device and a method thereof, which can manage data in a data structure format that can maximize performance when a blockchain system processes data. According to an embodiment, when <Key>:<Value> is stored, the final value is stored in a Log Structured Merge (LSM) tree data structure format, and the key used for storing the final value is separately stored in a B+ Tree data structure format, so that storage performance and reference (read) performance can be improved compared to those of conventional methods.
