Securitize, Redstone Pilot ‘Trusted Single Source Oracle’ to Secure Tokenized Fund NAVs

Key Points

1. The TSSO model is designed to reliably prove NAV updates on-chain for private funds, where NAV is calculated by a single fund administrator with no way to double-check.

2. The TSSO framework creates a cryptographically linked chain of NAV updates, using a cold-stored 'root key' for major updates and a 'chain key' for routine changes.

3. Securitize is leading the pilot of TSSO with some clients, leveraging its experience in issuing treasury funds and publishing price feeds via Redstone.

4. Tokenized funds are seen as a growth area for DeFi, and widespread adoption of models like TSSO could facilitate institutional participation.

5. The system aims to balance security with practicality, allowing NAV data refreshes without constant manual work.
