Rather than the abstract, the legality of a patent is based primarily on the claims. That's what you should be looking at to see if there's prior art. Here's claim 1:
1. A virtual currency transaction system, comprising: a non-transitory memory; and one or more hardware processors coupled to the non-transitory memory and configured to read instructions from the non-transitory memory to cause the system to perform operations comprising: identifying a first user primary wallet that is associated with a virtual currency and that includes a first user primary wallet private key; creating a plurality of first user secondary wallets that each include a respective first user secondary wallet private key; performing a respective virtual currency transaction using the first user primary wallet private key to transfer an association of predefined amounts of the virtual currency from the first user primary wallet to each of the plurality of first user secondary wallets such that at least two of the plurality of first user secondary wallets are associated with different predefined amounts of the virtual currency; receiving, subsequent to associating the predefined amounts of the virtual currency with each of the plurality of first user secondary wallets, an instruction to transfer a payment amount to a second user; and allocating a subset of the first user secondary wallet private keys to the second user, wherein the subset of the first user secondary wallet private keys are included in respective first user secondary wallets that are associated with predefined amounts of the virtual currency that equal the payment amount.
