A blockchain is a data-keeping ledger that can be distributed among a group but has safeguards to prevent data manipulation. Blockchain analysts examine the data in and usage of these ledgers to determine the effectiveness of the blockchain, identify areas for improvement, and develop strategies for implementing changes. This is still a relatively new position, and many companies are still determining both if and how to use blockchain analysis as part of their overall business strategy, so your daily responsibilities could vary greatly, depending on your employer. This job title currently refers to analyzing blockchain performance and should not be confused with roles that work with the programming or security of different blockchain systems.
