Sending USDT costs 2$ in gas fees on zkEVM, even though blocks are empty. That's almost the same cost as Eth mainnet.
Is it because calldata is posted on L1 and that's very expensive pre-4844?

This is probably the most important chart to keep an eye on for STEPN.

If EIP-1559 was live, the current ETH daily supply change would be -13,380 ETH. Averaged over a year, this would result in an annual deflation of 4%.

Stepn is using the same economic model as Axie where shoes are axies and GST is SLP. You earn GST by running, you burn GST by breeding shoes and you sell your new shoes or try to earn from them.

📉 We are now almost at -7,000 ETH a day, if EIP-1559 was implemented.
If this was an average, it would result in a yearly deflation of the ETH supply by about 2%.
Based on the last 24h worth of transactions, the daily issuance of ETH would be about -1056 ETH per day 📉. That's right, the total supply would decrease.

I want more contracts to start using a stateless design.
Want to run an NFT sale?
Put all sale parameters (price, isActive, maxSupply, etc) in a struct, hash it and *only* store the hash. Clients would then pass these when buying and they would be validated against the hash.

Hard numbers still pending, but this is very plausible. Near 60% of miners now use Flashbots, which pushes gas price auctions off-chains.
Bots don't see their txs failing when losing an MEV tx race, which means a lot less gas is wasted.
Overheard from a major mining pool:
"Flashbots is cause of recent low gas prices as traders shut down their PGA bots"

Reducing calldata cost by 10x means Ethereum based rollups can roughly execute 10x more txns, since the primary bottleneck of rollups *is* calldata.
Louis is suggesting we may be able to safely reduce calldata cost by a further 5-10x.
Following
@PhABCD
suggestion, I'm fairly positive we can push EIP 2028 further by a large factor
I have revisited EIP2028 analysis and the new data converged towards calldata having little impact on uncle rates.

Did you know 4337 adds ~60,000 gas to every transaction, in addition to the already more expensive AA transactions?
Situation is even worst on L2s, where calldata is going to be priced higher.
Did you know 4337 forbids AA wallets being signers of other AA wallets?
Forget building user friendly multisigs, EOAs will always be needed under 4337 reign

If you are doing a decently large trade on a dex, might as well put gas price to 1 Gwei and wait for a Flashbot to pick it up and sandwich you. You will be sandwitched anyway, so might as well not pay gas fees for it.

10 days after being reported to the Geth team, a fix has been merged 🎊!
Hopefully we will see an impact on gas prices once miners start using the Geth version including this change. The backrunning bots tracked on Dune consumed 500B gas with spam txs.
Turns out the numbers are concerning. Due to this Geth feature, ~$2.5m in gas fees was spent by backrunning bots, which is almost 40,000 blocks filled with spam txs.
Their activity exploded in a last few months. Yesterday alone, these bots used close to 10% of all block space.
