What hashrate threshold keeps DAGKNIGHT secure?

DAGKNIGHT maintains its security guarantee as long as honest miners control more than 50% of total hashrate. In any proof-of-work system, security hinges on who holds the majority of mining power — if honest participants control more than half, they can keep the network in check. DAGKNIGHT meets this standard while also making fewer assumptions about how the network behaves, such as how quickly messages travel between nodes. For a beginner, this means DAGKNIGHT does not ask for a stricter majority than Bitcoin requires — it just delivers that protection in a more resilient way.
