Fil_Fil Product: 
a small incentivized data network overlay on top of filecoin specifically for filecoin snapshots
User requirement: snapshots are incentivized to be stored for a long time, ~2-5 years with replication
User requirement: snapshots are committed in real time < 1 hour after they are generated 
User nice-to-have: snapshots are available for content delivery on the saturn network

Big idea: providers participate in the network for an incentive.  Users of the network get guarantee that snapshot data is stored and (ideally) a reliable way to get the snapshot data out if they pay.  Basically it is like filecoin but for a tiny subset of specific data.

Users: 1. People installing lotus who need to sync (ideally FilecoinFoundation would subsiize saturn payments for people downloading from lotus-chain management website within reason 2. SPs who are out of sync 3. Devs / analysts who need historical data

AMT Churn Explanation

Background

Market Churn

Churn is defined to be the size in bytes of the data in a datastructure that is overwritten over some period of time. Because GC in lotus is somewhat difficult lots of churn in filecoin state has a high system cost

We learned after nv19 that AMT churn is > 100x higher than optimal

Contract as a Deal Client for Archiving Filecoin Blockchain Message Data

Motivation

1. Use web3 infrastructure to solve the filecoin message archive problem currently solved with web2 clouds
2. Provide an EVM contract template for contract as a client data storage on the filecoin network
3. Identify sticking points in the current model of data preparation, data transfer and deal negotiation for contract as a client storage deals. For example learn how the ask protocol should change to support this model.
4. Demonstrate a new model for FIL+ auditing with significantly better fraud resilience properties

The core idea is that as system and protocol developers we will benefit from building a small application to understand how to adapt the network to similar applications. The nice thing is that fil infrastructure has a concrete application today which serves PLs broader goal of using our own tech.
