The architecture of @Treehouse Official is actually very simple, with the core being tAsset and DOR, supported by five different roles.
tAsset is an upgraded version of LST, such as tETH, which can earn more income through interest rate arbitrage in addition to the risk-free interest rate on the chain. DOR is a decentralized interest rate benchmark that relies on everyone to provide reliable interest rate data and forecasts.
The division of roles is also clear: Operators (like Treehouse itself) start DOR and maintain its operation; Panelists are whitelist institutions that report interest rates using proprietary models; Referencers incorporate DOR data into their own financial products; Delegators entrust tAsset to Panelists, receiving income without losing ownership.
With this whole setup, it ensures income while making the interest rate data reliable, and the logic is very coherent.
