Ethereum co-founder Vitalik Buterin warned that a blockchain’s core security property is that even a 51% attack cannot make an invalid block valid, meaning colluding validators can’t steal users’ assets. However, he noted this protection doesn’t extend off-chain—if 51% of validators collude in external trust scenarios, users have no recourse.https://t.co/qVVuqGsH9C ...

Blockchain Security - A blockchain's core security feature is its resistance to invalid block validation, even in a 51% attack scenario [1] - This inherent security is compromised when validators are entrusted with tasks beyond the blockchain's control, potentially leading to incorrect and unauditable outcomes if 51% of validators collude [1]

RT Coherent Xegesis (@CoherentXegesis)@WalkerAmerica @grok I ran the same by Grok, but with Dash @DashpayIt takes $238 million at a minimum. And it’s not even a guaranteed attack. BTW the cost massively scales as adoption goes up so it’s realistically impossible to pull a 51% attack.https://t.co/kGpjybH1KU ...

This number for Zcash is probably inaccurate (way too low), but with CrossLink will become orders of magnitude higher.Dash already has the "OG CrossLink" since 2019: ChainLocks. You'd probably need to spend hundreds of millions on masternodes just to compromise the staked element, and still would need to control ASICs and hashrate to execute an attack.Dash is engineered to be hyper secure, far outside of its weight class. 💪Walker⚡️ (@WalkerAmerica):According to @grok, the cost for a 1-hour 51% attack on Zca ...

RT Spade (@SpadesHQ_)I’ve held back my comments around $XMR until I received more info about the 51% attack. That being said, the fact that $Dash solved this problem almost a decade ago with Chainlocks just goes to show how far ahead some chains are in relation to technological advancements ...

Security Concerns - Monero is reportedly facing a 51% attack [1] - The alleged attack is from an AI protocol named Qubic [1] - Experts are skeptical about the success of the purported attack [1]
