Struct ChainedBeaconAnchor

Source 
pub struct ChainedBeaconAnchor { /* private fields */ }
Expand description

A chained anchor that enables verification through multiple beacon chain state transitions.

This structure extends the basic beacon anchor concept by allowing verification through a chain of state transitions. It’s useful when you need to verify an execution block against a beacon chain state that’s not directly accessible via EIP-4788, but can be reached through a series of intermediate states.

The chained anchor works by:

  1. Starting with an execution block and its beacon root (via EIP-4788)
  2. Following a chain of beacon chain state transitions through intermediate states
  3. Ending at a reference beacon chain state that can be independently verified

Each step in the chain verifies:

  • The previous beacon root matches the current state’s stored beacon root
  • The current state root is properly included in the next beacon chain state

This enables verification of execution blocks against historical beacon chain states that may not be directly accessible, creating a cryptographic chain of trust through intermediate consensus states.
