According to CoinDesk, tokenized asset issuer Securitize and oracle provider RedStone have released a whitepaper aimed at introducing a new model for securely verifying on-chain net asset value (NAV) data, specifically for tokenized private equity funds. The model, called Trusted Single Source Oracle (TSSO), is designed to address a key gap in decentralized finance ($DeFi) infrastructure: how to reliably prove that each asset net value update actually comes from a trusted source and cannot be tampered with once it is on-chain.
