why does not bitcoin change from10 minutes to shorter per block ?

[philsong]

someone always complain about the tx time long, and some altcoins change the tx time to shorter, so it should be easier to change this time, why btc does not change it, any reason? safe? or? thx

This has been discussed many times. I suggest searching on the bitcointalk forums, or stack exchange.
And anyhow - this is not the place for this discussion as it affects the bitcoin network as a whole not just this client.

@philsong This is a forum for reporting issues/bugs only. Bitcoin is DEFINED by the 10 minute block frequency - if it was anything other than 10 minutes, it would become an altcoin by definition.

Exactly

Thanks a lot, any key words, cannot find the answer about this question so ask in here. anyway ,thx a lot. but I still cannot understand why you cannot change to much faster after a special block to avoid fork, definition is right, but it would be better why cannot change definition?

@philsong feel free to fork bitcoin and do just that. good luck.

i would not do a altcoin, just ask the root reason....
