# Usage: ./start_and_monitor_livepeer.sh <LIVEPEER_ARGS>
# <LIVEPEER_ARGS> should be the flag arguments you would use with the livepeer binary
# Ex. `livepeer -network mainnet -orchestrator -transcoder` would instead be:
# `./start_and_monitor_livepeer.sh -network mainnet -orchestrator -transcoder`

This gist contains a script for marking expired tickets in a node's DB so the node does not continuously try to redeem tickets that have expired. This will be fixed in the node in an upcoming release, but for now you can use this script to address this issue.

Usage

First, make sure you have sqlite3 installed. You can check by running which sqlite3 and if there is a path returned you have sqlite3 installed. If you do not have sqlite3 installed:

• OSX: brew install sqlite3
• Ubuntu: apt-get install sqlite3

1. git clone https://gist.github.com/ea57cfe9510b6526288d456229a3d61e.git

The findings below pertain to the Livepeer protocol smart contract code at Git commit hash 2889ad2d5f20507d58701acf4d47a0551e593c04.

Findings

1. If a registered transcoder A is delegated to another registered transcoder B, transcoder A will not be able to claim its reward cut as a transcoder

Description

Whenever a transcoder calls BondingManager.reward(), the newly minted inflationary tokens are placed in a reward pool for the round in which the tokens were minted. Both transcoders and delegators claim their reward shares for reward pools in past rounds by either explicitly
