Abstract: A method for valuation of a vehicle based on telematics includes: storing a plurality of vehicle profiles, each related to a vehicle including a vehicle value and associated telematics data points; receiving a plurality of telematics data points associated with a target vehicle; identifying a subset of vehicle profiles where there is a correspondence between the associated telematics data points and the received plurality of telematics data points; estimating a valuation of the target vehicle based on, for each vehicle profile in the subset, a combination of the vehicle value included in the respective vehicle profile and a level of similarity to the received plurality of telematics data points and the associated telematics data points; and transmitting the estimated valuation to an external computing device.

Abstract: A method for guaranteeing a blockchain transaction includes: storing account profiles, each related to a transaction account including a current balance and identification data; receiving a blockchain transaction request including a sending identifier, receiving identifier, and blockchain currency amount; transferring an alternative currency amount based on the blockchain currency amount from a first account profile including the sending identifier to a second account profile including the receiving and sending identifiers; restricting access to the current balance in the second account profile from the first account; receiving a confirmation of a blockchain transaction within a predetermined period of time; and transferring, from the second account profile, the alternative currency amount to the first account profile if the confirmation is received within the predetermined period of time, or to a third account profile including the receiving identifier if the confirmation is not received within the predeterm
