BlockChat is a university project developed at the National Technical University of Athens aimed at creating a simplified blockchain platform. It allows users to engage in secure and reliable cryptocurrency transactions and message exchanges using a dummy Ethereum-like token called BlockChat Coin (BCC).
BlockChat is dummy-cryptocurrency focusing on transaction handling and block validation using a Proof-of-Stake consensus algorithm. Users can perform secure transactions and message exchanges within a decentralized and distributed environment without the need for a central authority.
- BlockChat Wallet: Each user has a wallet containing BCCs necessary for making transactions and sending messages.
- Transactions: Users can send BCCs or messages to other wallets. Transactions incur a fee, calculated as a percentage of the transaction amount for currency transfers or based on message length.
- Consensus Mechanism: Utilizes a Proof-of-Stake algorithm to validate transactions and form new blocks.

Configure Network Settings:
- Edit
./src/.envto set theBOOTSTRAP_IPandBOOTSTRAP_PORT. - Adjust the prefix for private IPs in the network in
wserve.py line 23.
- Edit
-
Starting the Application:
- Open a terminal for each node and navigate to the project directory.
- Run the following command to start the BlockChat client:
bash entrypoint.sh TOTAL_NODES BLOCK_CAPACITY - Replace
TOTAL_NODESwith the number of client nodes, andBLOCK_CAPACITYwith the desired transactions per block capacity.
-
Run Tests:
- Execute the test script to simulate network operations:
bash test_entrypoint.sh TOTAL_NODES BLOCK_CAPACITY [COMPUTE_JUSTICE] - The
COMPUTE_JUSTICEparameter (optional) influences initial staking amounts, with a default setting ofFalse.
- Execute the test script to simulate network operations:
- For containerized setup, please refer to the Docker branch and follow the provided instructions.
