The Ethereum Blockchain transition from proof-of-work (POW) to proof-of-stake (POS) consensus mechanism took place on 15 Sep, this process known as The Merge, but JPMorgan is concerned about this Merge, JPMorgan said in a research report on Wednesday.

The change was successful , splitting of blockchain into two and giving rise to an offshoot chain called Ethereum PoW. Some people are happy with this transition and showing there support towards the forked version, which still uses PoW verification , and at least 19 former ehter mining pools are active on it , the report said. This may cause the division of Ethereum community in two.

JPMorgan note that the price of ether(ETH) has declined sharply. This drop was caused by a combination of "buy-the-rumor/sell-the-news flows specific to Ethereum’s merge event".

The Merge was done in two phase, the first stage codenamed Bellatrix, happened on 6 September 2022. The second stage, Paris, happened on 15 September 2022 which completed the merge process.
