Although, this question is related to the Bitcoin network; however, its calculation is more relative to the Mathematics. So, let's bring it up here:
According to this answer: https://bitcoin.stackexchange.com/a/58908/41513 a Byzantine Fault Tolerant (BFT) consensus threshold is 1/3.
On the other hand, there is a common belief that Bitcoin network is secure till majority of mining power (i.e. more than 1/2) is honest, that means Byzantine Fault Tolerant threshold of Bitcoin network is 1/2.
Which threshold is correct? 1/3 or 1/2 ?
Note: The proof-of-work (PoW) that is used in the Bitcoin consensus is a Poisson process.

That "common belief" is out-dated. It has been know for a while that you don't need a majority. There is some debate about this, but then there is an article titled Why Selfish miners do not exist and never will that was posted a month before an alleged selfish mining attack.
