YMPL is a novel synthetic asset supported by probability, serving as a native store of value for the Ethereum decentralized ecosystem. Based on its probabilistic model, the token supply is reconstructed within a set of intervals; inspired by the Ampleforth protocol, we further refined their rebasing model to create a new digital commodity. The YMPL protocol allows anyone to rebase every 4 hours, with each rebase having a 25% chance of success.
