Printed	Page 13 First paragraph	There seems to be some text ( including subtitle) missing here. The title 'Introducing the Timestamp server' only goes along the first two lines of text. What follows next (hashing procedure) looks unrelated. Weird.	Hernan Gonzalez	Oct 30, 2021
Printed	Page 33 third item	The description of Hashes is seriously wrong. "A hash is a one-way encryption, meaning it is easy to encrypt the data" NO! It means you can go only in the "encrypt" direction, you cannot decrypt it because the function is many-to-one, not reversible. "It is extremely difficult, if not impossible, to decrypt the hash back to the original input data. The only way to decrypt a hash without a private key is through brute force" NO!!! You can't "decrypt a hash with a private key"!	Hernan Javier Gonzalez	Mar 17, 2024
Printed	Page 78 Figure 3-8	At the far left of Figure 3-8 under the shaded Ethereum block, "Address A: 100 BCT" should be "Address A: 10 ETH."	Bill Scharf	Aug 18, 2021
