Data Structures in Blade

This chapter provides a mapping between the main Ethereum data structures explained above and their implementation in Blade, the Ethereum client.

We answer the following:

• Where these data structures are located in the Blade source code?

• How they are manipulated or updated during runtime?

• The correspondence between Ethereum’s conceptual structures (e.g., tries, receipts) and Blade's internal representations.

This serves as a bridge between theoretical Ethereum architecture and its practical implementation in Blade.
