AIP-33 - Block Gas Limit

Summary

The per-block gas limit (or simply block gas limit) is a new feature that terminates block execution when the gas consumed by the committed prefix of transactions exceeds the block gas limit. This ensures that each block is executed within a predetermined limit of computational resources / time, thereby providing predictable latencies for latency-critical applications that involve even highly sequential and computationally heavy transactions.

@thepomeranian what kinds of DoS attacks does this introduce?

Perhaps a malicious validator stuffs in a bunch of no-ops in a loop order to crowd out oracle updates?

[Kuanishbek]

ddos attacks,,,,?

[danielxiangzl]

A malicious validator can always propose empty blocks, so this AIP does not introduce new attack vector.

[davidiw]

At worst case, a malicious validator can pollute a single round of consensus in which they are the proposer. Per what @danielxiangzl said this introduces no new attack vectors. Because the validator would be just as good not proposing any transactions at all.

top !! bravo le gars !

Ya, it was one of my quandary. But one thing that I fund is the gas is more descended since the first day.
