Abstract: Multi-phase crowdfunding systems and methods include goal-verified funding with real-time transaction confirmation. Issuance of reward points are optionally fungibly paired with blockchain tokens. Exclusive reward fulfillment is provided via user-determined auction mechanics. Overpledged funds can be automatically allocated. A replay auction mechanism enables retained participation through persistent bid units. A non-cash bidding economy is restricted to validated contributors.

Abstract: A method of making a polishing layer for polishing a substrate selected from at least one of a magnetic substrate, an optical substrate and a semiconductor substrate is provided, comprising: providing a liquid prepolymer material; providing a plurality of hollow microspheres; exposing the plurality of hollow microspheres to a carbon dioxide atmosphere for an exposure period to form a plurality of treated hollow microspheres; combining the liquid prepolymer material with the plurality of treated hollow microspheres to form a curable mixture; allowing the curable mixture to undergo a reaction to form a cured material, wherein the reaction is allowed to begin ?24 hours after the formation of the plurality of treated hollow microspheres; and, deriving at least one polishing layer from the cured material; wherein the at least one polishing layer has a polishing surface adapted for polishing the substrate.
