Abstract: A method for ensuring precedence for the processing of a blockchain transaction to prevent loss of cryptographic currency includes receiving a new blockchain transaction by a blockchain node in a blockchain network, confirming the new blockchain transaction including identifying a precedence transaction that was previously conducted and stored in the blockchain that involves both blockchain wallets included in the new blockchain transaction, including the new blockchain transaction in a new block that is generated, and distributing the new block to additional nodes in the blockchain network for confirmation and addition to the blockchain.

Abstract: A method for facilitating foreign transactions through inter-currency exchanges and geographical matching includes providing a platform to consumers located in different countries, where a consumer in a first country that desires a product from a second country is matched to a consumer in the second country that desires a product in the first country; the consumers are matched and transactions initiated by the platform to provide transfer of any necessary payment to ensure that each consumer can make the purchase on behalf of the other consumer in their own country, for shipping to the consumer in the other country, negating the need for the consumers to make any international purchases directly while still availing themselves of foreign products without involving merchants and minimizing the effect and amount of cross-border transactions.
