According to Avery Ching, the practice of MEV (Maximal Extractable Value) exploiting information asymmetry poses significant challenges to consumer protection in both crypto and traditional markets. He highlights the importance of encrypted transactions, as being pioneered by Aptos and adopted by DecibelTrade, in ensuring fair trading conditions. These systems prevent the revelation of transaction details until sequencing, thereby safeguarding users from value extraction and ensuring transparency. Ching asserts that centralized systems with privileged access to order flow fundamentally lack credible safeguards against MEV abuses, even under honest operators.

According to @1HowardWu, every gas fee paid on a public chain leaves a traceable on-chain record that lets observers correlate the fee-paying address across interactions back to a single identity (source: @1HowardWu). Private-by-default chains can implement protocol-level gas abstraction so the fee payer is never revealed, blocking behavior aggregation and identity inference (source: @1HowardWu). For traders, this means wallet clustering, address correlation, and on-chain surveillance remain viable on public chains but are significantly hindered on private-by-default chains with gas abstraction (source: @1HowardWu). Traders should not assume encrypted transaction payloads alone provide anonymity if the gas-paying address is visible on-chain (source: @1HowardWu).
