WEIGHT-BASED FINALITY

In the Zeqron BlockDAG, finality is a factor of the accumulated weight of the past-cone of a block. Once a block is "buried" under enough subsequent blocks, it becomes mathematically impossible to revert without breaking the consensus rules of the mesh.

PROBABILISTIC V DETERMINISTIC

• ::SOFT_FINALITY: Achieved in < 200ms once a block is accepted by local peers.
• ::HARD_FINALITY: Achieved when the block's Weight Certificate is signed by the required quorum of reputation-weighted nodes in the zone.

THE FINALITY GARDEN

Finality is monitored via the "Garden" engine, which tracks the density of confirmations across the lattice.

1. ::TIP_CONFIRMATION: New tips are selected based on their weight relative to the main chain.
2. ::STABILITY_CALCULATION: Each level of the DAG is assigned a stability score ($S$).
3. ::THRESHOLD_CROSSING: When $S > 0.999$, the block is moved to the immutable archive.

BYZANTINE RESILIENCE ($f$)

Ghost-Sync is designed to maintain finality even under conditions where up to 33% of the network's weight is controlled by malicious actors. The PQC-signatures ensure that identity-spoofing attacks (Sybil) are neutralized before they can influence the weight distribution.
