Livepeer

Following the conventions of Ethereum and many popular ERC20ERC20 tokens, LPT will be divisible by 10 ^ 18, with larger denominations such as the LPT itself intended to be used for user level transactions such as staking, and smaller denominations intended to be used for protocol accounting.

When a broadcaster submits a job to the Livepeer Livepeer Smart Contract, the protocol uses the current block hash to determine which transcoder will be assigned the job. Reorganizations of the underlying blockchain can cause confusion in this scenario. While this is not "an attack" directly, a transcoder will be valid one second, and then upon reorganization, will no longer be valid. When a reorg is detected the broadcaster can either redirect the stream towards the new valid transcoder, or the protocol can detect uncle blocks that are included in the main chain, and consider a transcoder to be valid if an uncle block within a given threshold would have made them valid.
