:::info Up to date by March 2021 ::: Authors: Danilo Lessa Bernardineli (BlockScience) Background context Shortly after Filecoin liftoff, a security issue was reported with the v1 proofs. The issue was fixed in v1.1 proofs, which were introduced in the Filecoin network version 7 upgrade, on November 25th, 2020. As a result of this upgrade: All new sectors had to use v1.1 proofs

Welcome to the BlockScience-Filecoin Cockpit! This is a one-stop resource for getting access to our public-facing research initiatives and roles as well as for gaining visibility on who we are, how we can help, and our history. Through this book, you'll be able to access parts of our work output across several initiatives. Many of the pieces of content are in intermediate stages or have been used for planning and communicating research. BlockScience is a complex systems engineering, R&D, and analytics firm. Our goal is to combine academic-grade research with advanced mathematical and computational engineering to design safe and robust socio-technical systems. We provide engineering, design, and analytics services to a wide range of clients including for-profit, non-profit, academic, and government organizations, and contribute to open-source research and software development.

:::info Up to date by December 2022 ::: Authors: Danilo Lessa Bernardineli (BlockScience), Jakob Hackel (BlockScience), Jamsheed Shorish (BlockScience) Summary This document is a straightforward description of the main economic levers, or mechanisms, of Filecoin at both the microfoundation and macroeconomic levels. The description includes both mechanism goals and how these goals can be benchmarked in light of counterfactual scenarios, which help to answer the query, "what would happen if we didn't have those mechanisms in place?" Using this approach we aim to provide clarity on the rationale for the implementation of the associated mechanisms, as well as to provide directions on how to measure if the intended goal(s) of each mechanism is/are achieved, i.e. if they are successful.

Each topic has a paragraph for: Summary: A quick overview of the topic Why: Why the topic is important for the ecosystem

:::info Up to date by August 2020 ::: Author: Danilo Lessa Bernardineli (BlockScience) Synopsis The choice of the parameters for the alpha-beta filter can induce chaotic behaviour in the filtered variables due to the updating inertia, which is associated with lower parameter values. Mitigation is done through larger alpha-beta parameter choices, which can be justified through the fact that simulations with different sampling intervals must have different alpha beta values, and this is captured through the usage of a geometrical relation. Chaotic behaviour due to updating inertia

:::info Up to date by August 2022 ::: Problem Statement The deposit margin ($m_d$) is used as an estimator of an given Provider "effective" collateral. The goal of that term is to make sure that the provider will always have enough collateral to pay any incurred slashes. By being under-collaterized, there is an increasing risk that the provider will shirk into its commitments.
