+## MEV and EIP-1559
+
+<br>
+
+- The incorporation of EIP-1559 in the London hardfork brought a major restructuring of the Ethereum fee mechanism, aiming to allow for easier 
+fee estimation by users and consolidate ETH as the base currency of the network by burning part of the transaction fees. 
+
+- Under the new fee mechanism, instead of choosing a gas price for their transactions, users set a "priority fee" for miners to incentivize inclusion, 
+alongside a "max fee", stating the absolute maximum price that they are willing to pay. The protocol now sets a per-block "basefee", computed 
+programmatically from the amount of gas used in the block immediately before, in a negative feedback loop meant for block sizes to stabilize 
+around a target size $s_0$ (initially equal to the maximum current block size). 
+
+- Valid transactions pay a gas price equal to the basefee plus the 
+prioirity fee (only up to the max fee needed in case of sudden basefee increases). The prioirity fee goes to the miner, and, crucially, 
+the basefee is burnt.
+
+- Implications for MEV-related infrastructure: eliminate the possibility of zero-Gwei transactions, which are presently used for front-running 
+protection in some DEXes like MistX, where miner fees are taken directly from the transferred tokens.
