Notes This procedure activates Teleport attestation, a major new feature that will allow Dai users to perform fast withdrawals from L2 chains to Ethereum L1. To learn more about Teleport and how the Maker Oracles are used to enable it: Introducing Maker Wormhole (original name for Teleport) Teleport Oracle Overview Changelog

Running L2 nodes is considered safer than third-party RPC because if removes a trust element when attesting Teleport transactions. We recommend that Feed run their own nodes, but do not require it at this time. Optimism The Optimism project provides a set of docker-compose configurations to create a local replica node: https://github.com/ethereum-optimism/optimism/tree/develop/infra/op-replica A replica node includes two components: Data Transport Layer: Interfaces with an L1 Ethereum node to obtain L2 batch data. L2Geth: The L2 node itself, to which we will be interacting with.

Introduction Oracles-v2 v1.6 introduces two new software components, gofer and spire, which will improve the robustness of Maker Oracles, as well as set the stage for future growth. gofer Gofer is a service that continuously polls the data sources and provide aggregated data to omnia. gofer duplicates the functionality of setzer and will become the primary data source for omnia. Omnia reverts to setzer when gofer fails. gofer caches the API responses, which will greatly reduce the quantity of API requests and will allow omnia to cycle much more quickly through the expanding list of asset pairs.
