Multiple video game consoles each store a blockchain ledger with multiple blocks, which is either associated with a particular video game or with a the particular type of video game console that the video game consoles are each characterized by. One of the consoles receives a message identifying an intended transaction corresponding to transfer of an identified quantity of an in-game virtual asset from a transferor account to a transferee account. The console verifies that the intended transaction is valid and generates a new block that includes the transaction, optionally one or more additional verified intended transactions, and a block header that includes a hash of a most recent block in the blockchain ledger. The console appends the new block to the blockchain ledger and transmits it to the other consoles, which each also append the new block to their copy of the blockchain ledger, thereby completing the transaction.
