# Efforts to ensure the stability of Paladeum currency Our core goal is to enable Paladeum Coin currency to maintain its purchasing power, have a long-term stable value, and gradually develop into a medium for large-scale transactions and savings. Therefore, Paladeum currency first needs to have a clear value, and keep its price fluctuating within a narrow range around the value. We hope that the value of Paladeum currency can be linked to the value of a legal tender. The challenge to solve this problem lies in the following two aspects. First, generally speaking, the exchange rate of a legal tender cannot be read directly on the blockchain. Secondly, Paladeum currency has a time-sensitive price in the secondary market and is also exogenous to the blockchain, so the agreement must rely on a decentralized method and technology to estimate the real exchange rate. The core technology to solve this problem is called the exchange rate oracle. **The operation method of the exchange rate oracle machine is as follows:** * Exchange rate prediction machine * How to use the Oracle system to divide into Paladeum Cash, which has a stable currency system, and Paladeum Coin, a variable-backed currency --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
