What security guarantee does DAGKNIGHT maintain?

DAGKNIGHT keeps the network secure as long as honest miners control more than 50% of the total hashrate — the same foundational guarantee underpinning all Proof of Work systems. In any Proof of Work network, security depends on who holds the majority of mining power. If honest participants — those following the protocol rules — hold that majority, no attacker can rewrite transaction history or spend the same coins twice. DAGKNIGHT preserves this guarantee even while removing the fixed latency parameters that earlier protocols relied on. For a beginner, that means DAGKNIGHT's flexibility does not trade away the core protection that makes Proof of Work blockchains trustworthy.
