solidity-livepeer-aragon-app

Livepeer Delegator Aragon app for managing Livepeer Delegation actions.

This project uses the Aragon Agent app (Agent.sol) for storing LPT and interacting with Livepeer contracts.

Initial development includes functions for Livepeer interaction as a typical bonder/delegator. These include the ability to call the functions: approve, bond, claimEarnings, unbond, rebond and withdrawStake.

Further investigation may be made into creating a Livepeer Transcoder app, some discussion here: livepeer/research#13

Project contents

aragon-livepeer-experiment

Initial experimental Solidity tests between the Aragon Agent.sol and the Livepeer BondingManager.sol. See the test file if interested.

livepeer-protocol

The full livepeer contract deployment for testing locally. Modified to compile with the current version of Truffle v5.0.6. Includes 2 extra truffle scripts:

• initialiseFirstRound.js for preparing the BondingManager to be bonded too after initial deployment.
• skipRoundAndInitialise.js for skipping a specified number of Livepeer rounds, required for speeding up the protocol for testing.
• rewardWithLpt.js for declaring account[0] as a transcoder, doing the necessary setup and calling reward.

livepeer

The Livepeer Delegator Aragon app uses a modified version of Agent.sol to workaround limitations with the aragonAPI. Uses the Aragon react-kit template. Currently includes basic functions including approve, bond, unbond, claimEarnings, withdrawStake and transfer.

Aragon DAO Rinkeby Installation Instructions

Experimental versions of the Livepeer Aragon app are available on Rinkeby through the aragonPM. Using the aragonCLI with access to Rinkeby through the staging environment you can install the current version of this app into an existing Aragon DAO on Rinkeby.

1. To install the aragonCLI:

   npm install -g @aragon/cli 

2. To get access to a staging environment you can download this project and cd into /livepeer then set the network endpoint and accounts as specified here: https://hack.aragon.org/docs/guides-faq#set-a-private-key.

Once setup, to see info about the app, including permission roles, contract functions available and current version:

aragon apm info livepeer.open.aragonpm.eth --environment staging

To install the Livepeer Aragon app into an existing Aragon DAO:

dao install <DAO Address> livepeer.open.aragonpm.eth --set-permissions open --environment staging --app-init-args 0x37dC71366Ec655093b9930bc816E16e6b587F968

Note the success of this call could be dependant on the permissions set in the DAO. Ensure the account connected can action the Manage Apps permission either directly or through a forwarder eg the Voting app. See Permissions -> Kernal in the UI to check.

After app installation the permissions can be modified through the UI or through the CLI. Roles available include:

• SET_CONTROLLER_ROLE
• APPROVE_ROLE
• BOND_ROLE
• APPROVE_AND_BOND_ROLE
• CLAIM_EARNINGS_ROLE
• UNBOND_ROLE
• WITHDRAW_STAKE_ROLE
• TRANSFER_ROLE

Depending on your set up, they may require parameter permissions to be set to restrict access to certain functions. A preliminary script for modifying parameter permissions can be found at /livepeer/scripts/grantPermissionWithParameters.js

Local Deployment Installation Instructions

1. Install dependencies:

   npm install -g truffle 
   npm install -g @aragon/cli 
   npm install (In /livepeer directory)
   npm install (In /livepeer-protocol directory)
   

2. Startup local chain and IPFS, in separate terminals run:

   aragon devchain
   aragon ipfs

3. Prepare Livepeer contracts, execute in the /livepeer-protocol directory:

   truffle migrate  
   truffle exec scripts/livepeerAragonApp/initialiseFirstRound.js

4. Copy the Livepeer Controller address, found during the Livepeer deployment after truffle migrate, to the package.json relevant script.

5. Compile with the local version of truffle, execute in the /livepeer directory (this is necessary as the Aragon CLI truffle config doesn't optimize compilation):

   truffle compile --all

6. Deploy the Aragon Dao and Livepeer app, execute in the /livepeer directory:

   aragon run

To test the bonded amount increases as expected after reward is executed, bond to the main account in your local chain (if using aragon devchain it will likely be 0xb4124cEB3451635DAcedd11767f004d8a28c6eE7) and execute this in the /livepeer-protocol directory:

truffle exec scripts/livepeerAragonApp/rewardWithLpt.js

Finally, before unbonding or withdrawing, you must skip one or more Livepeer rounds and initialise the latest one. To do this, modify the constants as necessary and execute this in the /livepeer-protocol directory:

truffle exec scripts/livepeerAragonApp/skipRoundAndInitialise.js
