The new code update called BIP 91 has been locked in with 93.8 percent of miners showing support for the proposal in the last 24 hours, according to Coin Dance, a site which tracks bitcoin blocks.

It is essentially a software update that miners need to run. So 93.8 percent of miners are signaling their intention to run it.

There will now be a two-day grace period for miners to prepare for the activation of BIP 91. Following that, there will be an adjustment period which could take two weeks. The actual increase of the block size might not take place until November.

And there could be some potential issues. For example, one bitcoin developer Bryan Bishop, said that miners might not upgrade their software, even though they are signaling that they will.

And there is still a bit of caution in the market.

"It's premature to say the worst is over. But we have reached one important milestone down the road in bitcoin scaling. And there are a few more milestones coming up," Bobby Lee, CEO of BTCC, a bitcoin exchange told CNBC by phone on Friday.
