Round 2 / Consensus Pledge design flaw fix

Who is this project for?

• This project impacts every participant in the Filecoin network. Everyone depends on the network’s consensus security to conduct daily business, such as proving storage and making payments - without this fix, that would have been threatened due to the network’s QAP crossing the baseline function from above.
• Network participants that this affects includes storage providers, token holders, ecosystem partners, secondary partners that may rely on the Filecoin chain for their own apps, and new startups that are building on top of the Filecoin network.

What pain points does it solve?

• This contribution solves the problem of weakening network consensus security due to a design flaw in the original protocol design.

What are the tangible benefits of this contribution?

• The tangible benefits are: 1) CryptoEcon research publication on the pledge mechanism and why the current protocol is in danger of a 33% attack and 2) updated builtin-actors codebase to include baseline bug fix. Both of these results in the network being more secure.
