Abstract: A method of reducing depletion of elements from an airfoil includes disposing a bond coating on the airfoil, where the airfoil comprises cooling channels. The airfoil includes a material that has an initial composition. A cooling hole is machined in the airfoil to contact the cooling channels such that a fluid travelling in the cooling channel may be discharged via the cooling hole. The machining of the cooling hole results in a formation of a depleted region around the cooling hole. The depleted region is depleted of a portion of the initial composition of the airfoil. A top coat is disposed on the bond coat. The airfoil is subjected to a heat treatment at a temperature effective to promote diffusion of elements from a non-depleted region to the depleted region around the cooling hole.

Abstract: A method of performing block generation may include receiving a request from one or more sources that includes task data associated with one or more tasks for an economy, context information, and an indication of a blockchain of a blockchain matrix to which the task data pertains. The method includes determining whether the task data corresponds to a qualifying transaction for the economy for recording in the blockchain and, if so, determining whether to approve recordation of the qualifying transaction to the blockchain. In response to approving recordation of the transaction, generating a new block for the blockchain that includes the qualifying transaction, and adding the new block to the blockchain.
