Added file hip-1193.md
This HIP defines the requirements and implementation details for transitioning the Hedera network from record and event streams to block streams. This transition is a critical step toward enhancing blockchain compatibility, improving data integrity, and enabling future network optimizations such as state proofs. The proposal outlines the coordinated changes required across consensus nodes, mirror nodes, and supporting infrastructure to ensure a clean cutover without service disruption. It specifies new storage paths, file formats, and mechanisms to handle the transition state, including a marker file approach to indicate the final record stream entry before blocks begin.
