“A blockchain is a growing list of records, called blocks, which are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. It is a ledger that records transactions in a verifiable, permanent way.”
“Geography is critically important to capture in a blockchain record, which is why we are now calling this a geoblockchain.”
“Adding location to the blockchain would provide enhanced security and validation because the same transaction cannot happen in two places at the same time. Use cases for blockchain being explored today include land title, supply chain, and data exchanges. The amount of data that will become available with systems like these is worth consideration and needs research.”
