On blockchain, UIPC (Universal IPC) and SIPC (Secure IPC) are frameworks that allows different network to talk to each other using a standard protocol. While UIPC acts as the universal courier, SIPC acts as the security guard. Together, they create "Internet of Blockchains". [Gemini](https://gemini.google.com/app/b8339d20bf7f33cf)
- [Cosmos IBC](https://docs.cosmos.network/ibc/v10.1.x/intro) & [Polkadot - XCM](https://wiki.polkadot.network/docs/learn-xcm) are two industry leading protocols for UIPC
- For the SIPC, **Zero-Knowledge Proofs** and **Rollup architecture** also "Trustless bridges" or "Cross-rollup communication" are often more frequently used terms in blockchain literatures.
