Are blockchain ledgers public?
Can you explain whether blockchain ledgers are public in nature, and if so, what implications does this have for the privacy and security of transactions recorded on the blockchain? Also, are there any mechanisms in place to ensure that sensitive information is kept confidential, while still maintaining the integrity and transparency of the blockchain network?

How many ledgers have been sold?
Excuse me, I was wondering if you could clarify something for me regarding the ledgers that have been sold. Specifically, how many of these ledgers have actually been sold to date? I'm trying to get a better understanding of the current market situation and the demand for these particular ledgers. Could you please provide me with an up-to-date figure or an estimate, if exact numbers are not available? Thank you in advance for your assistance.
