Abstract: In one embodiment, techniques include receiving, by a computing device associated with a payment service system, a request to create a blockchain-enforced contract corresponding to a new transaction between a merchant and a customer. Techniques include generating, based on analysis using machine-learned models of a transaction history associated with the merchant, a condition of the blockchain-enforced contract requisite for completion of the new transaction. Techniques includes generating the blockchain-enforced contract including the condition. Techniques include providing the blockchain-enforced contract to nodes in a blockchain network. Techniques include creating a blockchain transaction addressed to the blockchain-enforced contract and including information regarding the condition. Techniques include providing the blockchain transaction to the nodes. Techniques include receiving confirmation that the nodes have validated the blockchain transaction.

Abstract: In one embodiment, techniques include receiving, from a device associated with a merchant, a request to create blockchain-enforced contract corresponding to a new transaction between the merchant and a customer. Techniques include generating a condition of the blockchain-enforced contract requisite for completion of the new transaction. Techniques include receiving a selection of at least one option for determining that the condition is satisfied. Techniques include generating the blockchain-enforced contract and providing the blockchain-enforced contract to one or more nodes in the blockchain network. Techniques include receiving an input comprising information regarding the condition, creating a blockchain transaction addressed to the blockchain-enforced contract and sending the blockchain transaction to nodes in the blockchain network. Techniques include transferring a corresponding to the new transaction from an escrow account to a merchant account.

Abstract: Know your customer regulations and security concerns, among other reasons, motivate institutions to ensure that entities with whom the institutions have dealings are who they say they are. A block of the blockchain discussed herein includes entity verifications generated by institutions that participate in the blockchain. An individual verification may include a hash of personal information associated with an entity that was authenticated by an institution. An institution seeking to authenticate (or deny) an entity may receive personal information from the entity, hash that personal information, and search the blockchain for any matching verifications (e.g., by attempting to match the hashed personal information to hash(es) associated with a verification in the blockchain).

Abstract: In one embodiment, a method includes receiving one or more selected options for one or more of multiple contract conditions generated based on transaction information associated with a request to create a blockchain-related invoice and generating instructions for a blockchain-enforced contract based on the transaction information and the one or more selected options. The instructions for the blockchain-enforced contract correspond to a first nested contract including a first contract condition required for a transfer of a value and a second nested contract including a second contract condition required for at least a partial reversal of the transfer of the value. The method also includes, in response to receiving an input regarding the second contract condition, cause the instructions for the blockchain-enforced contract to be executed on a blockchain network.

Abstract: Apparatus and methods for bone cavity preparation. Formed broaching members may be supported inside a bone by a rotator. The broaching members may be bowed out inside the bone to create a cavity having a shape determined by the broaching members and bone anatomy.

Abstract: Embodiments of the present invention provide systems, methods and computer readable media for calculating the capacity of a provider by calculating, using biographical data representing the provider, a first total units of service that are available to be offered to consumers during a first time period; calculating a second total units of service potentially available from the provider for a proposed second time period using a projection based in part on a model of consumer demand for the units of service; determining a third total units of service that are unavailable during the second time period based on at least one known or projected unavailability; and calculating a capacity based on the third total units of service and the second total units of service, the capacity being a capacity for a proposed promotion representing a maximum total of instruments to be offered in the proposed promotion by the provider.
