Samson Mow, a well-known Bitcoin proponent, recently took to social media to talk about the centralization aspects of the upcoming Merge, which he claimed isn’t widely known.

Ethereum is in the countdown mode after the completion of the Bellatrix upgrade on Sept. 6 and is all set for the official transition between Sept.13-15, depending on the hashrate (computer power) input on the network. The Merge is slated to be triggered by a difficulty threshold called the Terminal Total Difficulty (TTD) at a value of 58750000000000000000000.

Mow claimed that while everyone thinks that the Merge will be triggered by pre-set threshold difficulty, there is one aspect that not many people have paid attention to. He said node operators have the power to overwrite the TTD value by a single line of code.

Mow cited a Galaxy blog post highlighting the key centralization issue with the Merge and claimed that Ethereum has knowingly suppressed this fact.

So how does the MeRgE actually get triggered? I was curious so I did some digging. I thought it may be set with a fixed mechanism or readiness threshold, but no. Someone, probably Vitalik, will just say “go” and then it happens. The complex charade is to mask the centralization. pic.twitter.com/PmxcTMU8J5

He noted that with few nodes that matter, “so those in charge can simply “feed the actual value” for activation time whenever they feel like it. What’s hilarious is they then make tracker sites to “predict” when it will happen.”

Cointelegraph reached out to Mow to get his perspective on the upcoming Merge and the centralization debate looming around Ethereum’s upcoming transition. Mow told Cointelegraph that with a move to proof-of-stake (PoS), the “centralization aspect of Ethereum would become
