Bitcoin Q&A: Block height, syncing, and validation
What is the purpose of the getblock command? Why would you need to know the block height? How do I see the balances of other addresses? Why can't we download a pre-synced copy of the blockchain without validating?
These questions are from the February monthly subscriber session and the fifth session of MOOC 11, which took place on February 23rd and March 1st 2019.
