Abstract: A system predicts a value estimate for a user who provides a service that involves moving among geographical regions (e.g., a transportation service). The system determines the value estimate by identifying a sequence of time periods, each time period having an associated set of geographical regions. Possible transitions between geographical regions in different time periods are analyzed, for example, using statistical or machine-learned models, to determine likelihoods that the user will move between the geographical regions from one time period to another, and to determine expected values for a transition. Such models may be trained or developed using historical service data and user profile data stored by the system. Transitions are analyzed over a sequence of time periods to determine accumulated values associated with estimated overall values for each geographical region. The system predicts an overall value estimate for the user based on the accumulated values.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for efficiently processing transactions on a blockchain. An example method generally includes receiving, at a relay service, a request to execute a transaction on a blockchain. Generally, the request includes a request to transfer a quantity of a first type of token on the blockchain from a transmitter wallet to a receiver wallet identified in the request and incurs a transaction overhead on the blockchain in a second type of token. The request is modified based on the quantity of the first type of token, the transaction overhead in the second type of token, and a policy defining a source from which the transaction overhead is to be retrieved. The transaction is executed on the blockchain based on the modified request without transferring the second type of token from the transmitter wallet to satisfy the transaction overhead.
