Those hashes can then be put together into a “block,” representing a set of hashes created around the same time, Gould said. Those “blocks” are linked together into “chains” of a series of blocks. By making this data available to all participants in the blockchain, each time data changes hands or otherwise needs to be verified it can be run back through the program to see if the hash is still the same. Cybersecurity is a concern, given several instances where blockchains have been hacked, Annunziato said. CBP is trying to decide what data should be put on the blockchain, and what can't, such as personal identifying information and trade secrets.
