6 years ago Related to this, but not exactly the same topic: efficient protocol-to-many fee release and payments. Each user needs to claim all the fees and rewards they're owed for each round, and this can get expensive. A mechanism like merkle-root based pool payments may be interesting to consider.

There are all sorts of challenges around making sure the proofs are available offchain, but also potential game-theoretic solutions involving staking, acceptance, and slashing in the case of invalid or non-available proofs. For example, transcoders (validators), could play an additional role in producing these proofs and accepting proposed ones, and then watchers could slash their deposits for any faults.
Livepeer's POC currently uses a deposit+claim payments system with custom logic for when broadcasters can withdraw their deposits and when transcoders get to draw from a broadcasters deposit. More efficient, secure, and attack-proof methods are likely available via generalized solutions like:
These solutions should be considered in not only the context of transcoding, but also for fair compensation for bandwidth in P2P data transfer as referenced in #3
