+- [Post-Mortem, Blob Propagation Issues (27/03/2024)](https://gist.github.com/benhenryhunter/687299bcfe064674537dc9348d771e83) In March 2024, after Dencun upgrade, blobs attached to blocks from certain builders propagated too slowly over p2p which caused a client implementation to miss few slots.

+- [Post-Mortem Report: Ethereum Mainnet DOS Incident (07/02/2024)](https://blog.ethereum.org/2024/03/21/sepolia-incident) It was discovered that there was a possibility for a Denial-of-service attack dating from when the merge happened to the dencun hard fork. An attacker could create a block exceeding the specified limit of 5mb and adding multiple transactions into the block each not up to 128kb while also making sure that the transactions within the block have a collective gas which is below 30 million. With this action most nodes will reject the blocks which will lead to minority nodes acceptance creating forked blocks and missed proposer rewards.

+- [Post-Mortem Report: Ethereum Mainnet Finality (05/11/2023)](https://medium.com/offchainlabs/post-mortem-report-ethereum-mainnet-finality-05-11-2023-95e271dfd8b2) The Mainnet had some disruptions, which led to blocks not getting produced leading to a significant delay in transactions reaching finality, this continued for two days and resulted in an inactivity consequence, the network fully recovered without intervention.

+- [Post-Mortem Report: Minority Split (2021-08-27)](https://github.com/ethereum/go-ethereum/blob/master/docs/postmortems/2021-08-22-split-postmortem.md) This happened when Geth tried to assign data back into memory after the `datacopy` operation. Instead of saving the data in a new location, it accidentally overwrote the original data, causing it to become corrupted.
