blockchain is a collection ofrecords (called blocks), where each block links to the previous block using cryptography. Eachblock contains cryptographic hash, timestamp and data relevant to its application. Think ofit as a distributed ledger where instead of information being stored in a database it is storedon the blockchain. Some examples of solutions that use a blockchain at its core are:1. Cryptocurrencies (however, for this project you may NOT do a cryptocurrency)2. Smart contracts3. Trading4. Supply chain management5. Anti-counterfeiting6. Healthcare7. Domain names8. Proof of existence9. Voting10. and many others!   Programming Language: Java The use of third-party libraries for primary functionally is strictly prohibited, however, third party libraries can be used for other functionality such as communications and visualisation (such as normal JavaFX, JFreeChart, GraphStream, JGraphT, Yworks, JUNG or JMonkey). The use of other data structures for auxiliary operations is…

2. An instructor created a submission folder for coding submissions from students. The instructor wants to maintain all access to the folder for herself, but wants to give the grading assistants 'read' and 'execute' permission to the folder. However, the grading assistants cannot change anything in the folder. She adds a group 'grader' with the grading assistants for the folder. Nobody else should have any access to the submission folder. The instructor should use : chmod ________ to set the access permission for the submission folder to achieve the above goal.   Hint: Indicate the decimal number corresponding to the permission.

Create a spreadsheet that takes eight values that a user inputs into eight different cells. Then create a row that transposes the cells to simulate a transposition cipher, using the example transposition cipher from the text. Remember to work from right to left, with the pattern 1 > 3, 2 > 6, 3 > 8, 4 > 1, 5 > 4, 6 > 7, 7 > 5, 8 > 2 where 1 is the rightmost of the eight cells. Input the text ABCDEFGH as single characters into the first row of cells. What is displayed?
