This repo encapsulates a livepeer multi merkle miner that runs with minimal setup. It uses mongodb as a database to keep track of generated addresses allowing you to startup immediately where your multi merkle miner left off. The merkle tree construction requires a lot of memory and as such requires powerful hardware to run.

If you would also be so generous, support our work and bond against our transcoder! https://explorer.livepeer.org/accounts/0x30b1cbcebe94c0da9f273c9a4ed759ad4e7a273e/overview

Make sure that your key is stored in the same exact format that the go-livepeer client would create, in the same location full/path/to/.lpData/keystore. The code will look in ~/.lpData and resolve where the key is as long as it is named and formatted as an encrypted JSON blob with the filename as the UTC creation time and associated address.
