Since the launch of Ethereum Merge, there has been a hot discussion going on regarding the decentralization of the transactions on Ethereum Mainnet. As Ethereum adopted the Proof of Stake mechanism, the blockchain experience new types of issues in terms of on-chain transactions.

The event of Merge made Ethereum "ultra sound money" as it is a good ETH burner that decreased the emission of ETH fundamentally. If you want to track the emission and burned ETH amount, visit ultrasound.money to view these cool charts.
Though ETH is now ultra sound and eco friendly, we have unlocked a brand new concern: Centralized Validators
Flashbots do not Validate Tornado Cash Txs
Crypto ecosystem fights for decentralization and censorship resistance in nature. When it comes to the actions taken by MEV Boost protocols, we are facing a mismatch between the "shared vision" and the reality in the operations.
MEV Boost relays refuse to validate some transactions. It may seem like they are not allowing some shady transactions of Tornado Cash, which occasionally allows bad actors to money launder, but that is just the first step that centralization shows up on the second top crypto project which has $31b Total Value Locked!
According to MEV Watch, 51% of Ethereum’s blocks produced yesterday were built by so-called “OFAC compliant” - Cryptobriefing
OFAC Compliance for the sake of what?
If, one day, U.S Treasury decides to blacklist those who used Binance, Coinbase, FTX etc, who will validate your transactions when MEV Maximum Extractable Value mechanism outperforms the rest of the validators?
I think the operators of Flashbots do not want to see the threat they bring with the semi-centralized concept that they are shaping. I do not feel happy for the recent Merge though the coin that I invested has 12 Gwei tx fees, more eco-friendly and less emission!
What they could not see is that this concept would be an amazing event for any other crypto that is not Ethereum. YET, crypto investors still see Ethereum as the base that they can store their crypto and digital assets knowing that it is a secure blockchain used by millions.
I ask myself this question: Could we create a safer blockchain for our digital assets rather than less inflation crypto with the recent Merge?
For now, we could not. We need more updates to fix some fundamental concerns IMHO!
How do you feel about it?
