My question is regarding the update of Bitcoin software. Is there any mechanism for a synchronized software update in the Bitcoin network?

Assuming you're talking about the specific software project Bitcoin Core, there is not, and this is very intentional. Core's developers (disclaimer: that includes myself) shouldn't have the power to force new software onto the network.

  • Then how does a change in consensus rules or any of the software module is updated on all the Bitcoin nodes? Aug 9, 2017 at 4:57
  • There isn't. People must choose to run new software of they want new rules. Aug 9, 2017 at 7:56

No there is not. Bitcoin is a protocol, and there are many different implementations of the protocol developed by many different people and groups. It would not make sense to distribute "new software" to all the different implementations.
