The answer to your question is b crowding out effect
Answer: hello your question lacks the required option, below are the missing options
A. The transaction data in the tampered block is deleted, and a copy is created with the same hash value.
B. The hash values of transaction data of subsequent blocks are validated, and the chain is broken.
C. The hash value for the entire block is nullified, creating a domino effect on all subsequent blocks.
D. The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues.
answer : The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues ( D )
Explanation:
What happens if a transaction data is changed in an earlier existing block in a Blockchain is that the Hash values of subsequent blocks will be updated as soon as they are tampered with and the chain will continue.
Blockchain is a specially design system for recording information, hence any change in data inputted in an earlier existing blocks that changes will automatically be updated as well in all preceding blocks.
Answer: b. 37, 40, 41, 42
Explanation:
The next four octal numbers after 36 is 37, 40, 41, 42.
The octal numeral system, which is also referred to as "oct" for short, is simply base-8 number system.
It is a number system whereby only digits from 0 to 7 are used and there are no letters or numbers that are above 8 that are used.
In this case, after 36, the next number will be 37 after which we go to 40 as we can't write 38 in the octal system. Therefore, the next four octal numbers after 36 is 37, 40, 41, 42.
