LukChain

Generalised BlockChain

Currently uses nightly features

Config

To use LukChain, a config.toml file needs to be setup to define different user profiles. This should follow the following structure:

[config]
[[profiles]]
block_size = 10
lookup_address = "127.0.0.1:8181"
lookup_filter = "user"
user_location = "user1.json"
bc_location = "blockchain1.bin"

[[profiles]]
block_size = 20
lookup_address = "127.0.0.1:8181"
lookup_filter = "miner"
user_location = "user2.json"
bc_location = "blockchain2.bin"

Each field can be ommitted if not needed. The use of each field in the program is:

• block_size: If the role chosen is Miner, this option will define the size of blocks that it will add to the blockchain and will distribute to connected nodes.
• lookup_address: Address to contact initially to obtain addresses of other nodes in the network to connect to.
• lookup_filter: Included in message to LookUp and allows filtering of address book members based on their role in the network.
• user_location: Location where information about user is stored when it is generated or needs to be retrieved on startup
• bc_location: Location of binary file containing local copy of blockchain
