At present, we have reached a preliminary strategic cooperation with one investment bank holding STO license, and plan to issue a number of securitization tokens based on real-world assets (real estate, etc.) on Lava mainnet in 2020. We have adopted the technical architecture of Confidential Asset, and used threshold signatures and ring signatures to verify UTXO. Under the premise of ensuring verifiability and traceability, we can hide asset information in transaction data. This technical solution will also be implemented in the first half of 2020.
