Past materials indicate that this block would have been 494,784, leading critics to say that developer Garzik had an “off-by-one” error and that, if carried out, the nodes planning to fork could have been caught in limbo. Garzik, in turn, has argued that the code is operating as intended in the absence of significant hashing power.
It also remains to be seen whether some – if any – of the nodes in question see their software changed. Data from Bitnodes suggests that a number of them reside on hosting services from companies like Amazon and Alibaba.
So unless that larger-than-1 MB block arrives, the nodes that are running the software will have to keep waiting.
