The protocol operates as a multi-party gam= e setting where an oracle ("worker") is provided with an arbitrary computat= ionally complex task (any Turing-complete computing, machine learning train= ing or inference etc) and the network is able to reach a consensus on wheth= er a result reported by the worker is true. The consensus is reached via op= tional rounds of verification and arbitrage. The protocol is cryptoeconomic= ally-safe, i.e. has a proven Nash equilibrium. The protocol was later trans= ferred to LNP/BP Standards Association (https://lnp-bp.org) and was kept in= a backlog of what can be done in a future as a layer on top of Bitcoin. I'd like to emphasize that Prometheus works on Bitcoin, requires just sever= al Bitcoin tx per task, and _doesn't require any soft fork_. All economic s= etting is done with Bitcoin as a means of payment, and using existing Bitco= in script capabilities. Link to the paper describing the protocol: Only today I have realized that Prometheus protocol can be used to build cr= yptoeconomically-safe (i.e. trustless) 2-way-peg on the Bitcoin blockchain = without any soft-forks: a "worker" in such a case acts as an oracle for som= e extra-bitcoin system (sidechain, client-side-validated protocol, zk rollu= p etc) validating it, and the protocol will reach consensus on whether the = state reported by the oracle is correct. In other words, this is an alternative to BIP-300 and other similar soft-fo= rks having the only purpose of doing 2-way pegs. It also enables the two-wa= y trustless transfer of Bitcoins between Bitcoin blockchain, RGB and, in a = future, potential new layer 1 called "prime" (to learn more about prime you= can check my Baltic Honeybadger talk ).
