High-Level Architecture
The main high-level system components for Cascadius are below. The decentralized nature of the EVM blockchain environment and existing indexing services greatly simplifies the overall infrastructural components of Cascadius.
EVM-compatible smart contracts: smart contracts for (a) Loans, and (b) Securitizations serves as the heart of the Cascadius system: verifiable and decentralized registries for proxied loan assets and securitized pools.
Smart contracts control the distribution of proceeds from the pool to holders of the securitization and enforce the distribution rules of the waterfall.
Historic information / payments & transactions are stored outside of the smart contract. The precise indexing technology / platform is still under consideration, but will store historic information for all collateral on Cascadius.
Smart contracts emit events when state changes or is modified on either the loan or pool / securitization objects; events will be consumed by the indexing nodes, our primary store of historic information.
As indexed historical data will be made public, users can query the index nodes for collateral information, build their own reporting, or utilize pre-built reporting from Cascadius. Reporting may be hosted centrally by Cascadius for faster access.
The pricing engine is a long-term goal given the compute-heavy nature of securitized products models. As a result, the pricing service may be a separate, centrally-hosted component of Cascadius. Details TBD.
These are the main components. We will update with integration guides & developer's guides closer to launch.
