The next bitcoin halving is on 11 Jul 2016
03:05:22, If volume of bitcoin transaction suddenly increases,will it bring halving much before 11 Jul 2016?Is more bitcoin transactions mean more block creation?
if a block has 10 transactions or 2000 transactions it does not matter.. a mining pool will still need to hash out a solution which takes about the same time..
it is not about transactions per block that change the timing of block creation..
however..
if mining pools doubled their hashing power by having twice as much ASICS running. they can potentially solve blocks faster (though this is not a doubling of speed as its more of luck and increasing chances rather than any fixed timescales).
and every two weeks when the difficulty adjusts to compensate. if the mining pools then double up again trying their hardest to solve 2016 blocks in well under the standard 2 week period.. then yes the estimated date of 11th of july halving, could be sooner.
in short its about increasing ASIC hashing power to always stay way above the difficulty. and not about transactions
