Create a program that simulates a blockchain manager, including the ability to create, remove, and synchronize nodes and blocks. Program must also create and load backups.
my_blockchain (also affectionately named BLOCH) is a program that imitates a blockchain system. A number of commands can be given to the program, including:
-
add node [NID]- adds a node to the blockchain, the node ID (NID) must be a positive number. -
rm node [NID]- removes a node from the blockchain. -
add block [BID] [NID]- adds a block with the provided block ID (BID) to a node. You can use * instead of a specific NID to add the block to all nodes. The BID can be any alphanumerical (no spaces or symbols please) string under 100 characters. -
rm block [BID]- removes a block from all nodes. -
ls- lists all nodes. You can use the commandls -lto list all nodes with their respective blocks -
sync- Synchronizes the nodes, with older blocks given priority. -
quit- Quits the progam and saves a backup.
The program's prompt provides useful information. The first character is either S if the nodes are synchronized or - if they are not. The second will be the number of nodes in the system.
my_blockchain automatically saves backups when using the quit command, and automatically loads a backup if it exists. The backup is stored in /backups.
To start using my_blockchain, simply run the following commands in the program's root folder.
$ make
$ ./my_blockchain
