Blockchain and Bitcoin
1. Describe Bitcoin’s money supply process. How many Bitcoins will a miner be able to add to a block around May 2024?
2. What was the Bitcoin reward for mining the Genesis block?
3. Use a Bitcoin explorer to find the hash of the last mined Bitcoin? Attach a screenshot
4. How are the blocks in a blockchain linked to each other?
5. Why blockchain’s deep history is immutable and why it is a key feature of bitcoin’s security?
6. Use the Merkle-Damguard transformation, to find the block size on a 1024-bit input, provided the process uses the SHA-256 hash function.
7. In a key generation process for the Wallets, the following keys are generated from the keyword: TorontoMetropolitanUniversity
i) 000000000000000000035fab388f997dc93abbda7824601bde3293f08920a7a7
ii) c7f0df82e1e3cedf794a9164bbd840d018cad83000d16beb8e4f0579195b1cc7
And another process is run to create the following keys from the corresponding random number. Here are the numbers:
Random Number Key
2656192 cde3293f08920a7a9
2811233 890cfbdbbfe7aeaa9
In this given example, which keys are Deterministic, and which ones are non-deterministic?
Please complete the following table to answer this question:
Keys for Deterministic wallets Keys for non-deterministic wallets
8. How is a signature validated by using Public Key cryptography?
9. If the SHA-256 cryptographic hash function is applied on the header of a Block in the blockchain then what will be the length of the generated hash code?
