Here’s a chart I made of the marginal cost for one million gas on Ethereum since base fees were introduced. Log10-scaled.
The quantized steps are a brilliant hack. Nice work!
The primary effect of this EIP is to allow computation/communication gas to become cheaper in dollar terms and as a result unlocking more applications that are both storage-light and infeasible at current gas prices.

| Usage: | |
| python dedup.py [--dry-run] <dir1> [dir2] ... | |
| Duplicate files (same length + same SHA-256) are moved into a DUPLICATE/ | |
| subfolder inside their original parent directory. The "best" copy (shortest | |
| filename, then shortest directory path, then alphabetical full path) is kept |

Hello Team, Hope you are doing well!
CRITICAL! Almost all USDC liquidity on the REKT/USDC uniswap pool can be stolen, due to an authorization issue with burnFrom() on the REKT token.
Uniswap v2 pools get the prices for their swaps by comparing the relative amounts of each of the two tokens that they hold. If the pool holds very little of token A, and a lot of token B, then it only takes a little of token A to buy a lot of token B.
Currently REKT and USDC are fairly priced in the pool. If there were to suddenly be very little REKT in the pool, but the same amount of USDC, then very little REKT would be able to buy a lot of USDC.
