Securitize, one of the largest tokenized asset issuers, and the Oracle provider Redstone has released a whitepaper, as they say, introduces a new model to safely verify the net value (NAV) Data on-chain, tailored specifically for tokenized private funds.
The model, called the trusted single -source oracle (TSSO)is designed to tackle a keygap in decentralized financing (Defi) Infrastructure: How to prove reliable that each NAV update really comes from the trusted source and has not been manipulated once on the chain.
In traditional crypto markets, oracles pull data from multiple pricing to protect against manipulation or errors. But for private funds, NAV is calculated by a single fund administrator. It creates a unique problem: There is no way to double control the number through the market aggregation. For defi protocols that depend on accurate security values, this single point of trust has been an adhesive point.
The TSSO frame resolves this by creating a cryptographically linked chain of NAV updates, according to WhitePaper. Each update includes a secure digital signature, a timestamp, a reference to the previous mail and a hash that locks the sequence together. The system uses two keys: a cold -sized “Root key” for larger updates and a “chain load” for small, routine changes that remain within tight thresholds. This design aims to balance high security with the practical need to update NAV data without constant manual work.
“We need to make sure that we can fully authenticate the information, that we can check that no one compromises the data and we can only rely on a single source. Therefore, the whole process must be taken to the next level – so that’s the challenge,” said Jakub Wojciechowski, the founder of Redstone, in an interview with Coindesk.
According to Wojciechowski, Securitize takes the lead for the development of the product, “building kind of like an internal blockchain, which is a chain with the price updates,” he said. “We know they will not miss any single price update because the next price update is cryptographically linked to the previous one.” Then “When everything is signed correctly, we gather the opportunity to verify that the data really comes from the source.”
Tokenized funds are largely seen as one of the next major growth areas for blockchain. But their success depends on bridging the trust between traditional funding and cryptoinfrastructure.
While still early, efforts highlight the growing push to build institutional quality infrastructure for defi. If it is widely adopted, models like TSSO could make it easier for tokenized means to integrate with on-chain tools.
Securitize said it is already piloted TSSO with some of its clients and that it hopes to make significant progress and make it more widely available soon.
“This is open to the industry, but for Securitize it is very natural for the assets we are dealing with,” said Jorge Serna, Chief Product and Technology Officer at Securitize. “We have issued the Treasury Funds and Credit Funds, which are either the transfer agent or the fund’s administrator or perform both functions, and we are already, especially for those who publish price feeds via Redstone. And then this is something that we certainly want to secure between Securitize and Redstone.”
