The system is composed of three components: the Fault Proof Program (FPP), a Fault Proof Virtual Machine (FPVM), and a dispute game protocol. The OP Stack enables the independent development of the FPP and FPVM. This isolated design paves the way for the creation of multiple proofs, including ZK proofs. In the future, developers will have the ability to build custom fault-proof systems. Dispute Games serve as mechanisms for resolving discrepancies and establishing truth amid conflicting claims. Optimism also included the OP Stack fault-proof alpha release in its Immunefi bug bounty.Yield Protocol Winds DownYield Protocol, which offers fixed-interest yield farming, announced that it is winding down operations. The protocol will maintain support until the conclusion of the current loan series on December 29th, foregoing the launch of the March 2024 fixed rate series. Borrowing and lending will be fully disabled by December 31st. The protocol will then be in withdrawal-only mode for a limited period of time. The shutdown comes in response to an inadequate demand for fixed-rate borrowing, alongside regulatory challenges encountered in the US, Europe, and the UK.
