Is Time-Stamping on a Blockchain Inherently More Reliable than on a CEX?

Blockchain time is more tamper-resistant due to decentralization but less precise (block time) than the sub-microsecond accuracy of a CEX's centralized system.

Is Time-Stamping on a Blockchain Inherently More Reliable than on a CEX?

Yes, in a sense. Blockchain time-stamping is decentralized and cryptographically secured by the consensus mechanism, making it highly resistant to tampering by a single entity.

The time is recorded by the block producer and verified by the network. CEX time-stamping relies on a centralized, proprietary system, which, while highly accurate, requires trust in the exchange's internal controls and auditing.

However, blockchain time is only accurate to the block time, not sub-microsecond CEX precision.
