◼️47/100: Block-by-Block: Cryptographic guarantees

One thing I learned about: Cryptographic guarantees

• Confidentiality: Only we can access it.
• Authenticity: They were the ones who sent it.
• Integrity: This is what they have sent.
• Non-repudiation: They really have sent it.

+ Data availability: We can access the data.
+ Data verifiability: We can tell this about the data without reading the data.
