VBK is not merge mining:
# Merge mining requires that the primary and secondary blockchain both have the same mining algorithm; VBK-secured-altchains do not.
# Merge mining requires that the primary chain's miner actively participate, and therefore only a small subset of such miners do. VeriBlock Proof-of-Proof does not require such active participation, VBK PoP transactions are standard BTC transactions paying standard BTC fees, and thus included in by default.
# Merge mining requires the primary miner to run a second node - Whereas BTC miners do not need to run a second node for VBK.
# Merge mining allows one to attack the secondary actively while still mining the primary actively , i.e a "merge attack" instead of merge mining.
