A » The global clock assumption problem in blockchain refers to the challenge of synchronizing time across a decentralized network. Since nodes may have different local clocks, achieving consensus on the sequence and timing of transactions becomes difficult. This issue can lead to inconsistent data states and complicates coordination, particularly in proof-of-stake and proof-of-work protocols, where precise timing is crucial for validating and ordering transactions.

A »The global clock assumption problem refers to the challenge of synchronizing nodes across a decentralized network, like blockchain, assuming a global clock. It is difficult because nodes have different processing times and communication delays, making it hard to achieve a unified timestamp, which is crucial for transaction ordering and validation.
