A simple blockchain node in Typescript developed for teaching

1. Install dependencies using npm install pkg.json
2. Compile using tsc
3. Run using node index.js to connect with full network on port 18018. Run using bootstrap.js if you want to run on server-only mode on port 18020

If you ever want to clear all objects and blocks stored in the database, run node clear_databases.js.

Check the file constants.ts for different protocol parameters, including which miner to use (Typescript/C++), number of threads, name of the node, etc. Please change myName and minerName so that different nodes using this implementation can be distinguished.

To mine using the C++ miner (which is much faster), do the following:

1. Clone the repository and init the submodules:
   git clone --recurse-submodules https://github.com/ssrivatsan97/easycoin

2. Install cmake to build, you will need a C++ compiler like gcc clang:
   brew install cmake

3. Create a build directory and run cmake to compile the C++ miner code:
   mkdir marabu_miner/build
cd marabu_miner/build
cmake ..
make (If the above doesn't work on Ubuntu, try running make from the marabu_miner directory instead of from marabu_miner/build and then move the executables HashRateThread and MinerStandalone into marabu_miner/build.)

4. After compiling the C++ miner, change minerType in constants.ts to "cpp". Check that cppMinerPath points to the correct path for MinerStandalone. Then compile using tsc and run index.js as usual.

5. You can also check the hash rate of the C++ miner by running ./HashRateThread from within the directory marabu_miner/build.

Many thanks to marabu-miner-test for the C++ implementation!
