What Role Does the “Hashing Power” Play in the Security of the PoW Component of PoA?
Hashing power, which is the total computational speed of all miners, provides the initial layer of security for Proof-of-Activity. It ensures that the block template generation is computationally expensive and verifiable, preventing easy spamming of the network with templates.
A higher total hashing power means an attacker needs a significantly larger and more expensive investment in hardware to gain a majority share for the PoW phase, securing the initial block creation.
