Ozone Blockchain

Ozone is an entirely self-developed blockchain compatiable with IPFS to ensure continued decentralization.

Breakdown

BLOCK_ARC:

• block.cpp - Defines block contents, manages hash generation, defines print parameters.
• blockchain.cpp - Initialized genesis block, manages and validates chain.
• hash_utils.cpp - Manages hash/key/signiture generagtion and calculation.
• ipfs_utils.cpp - Uploads data to ipfs from a given node.
• proof_of_work.cpp - Outlines mining system, hash difficulty, and nonce creation,
• transaction.cpp - Defines transaction structure.

NETWORKING:

• ipfs_actor.scala - Grabs dats from ipfs http link with specific hash (hard-encoded as of now).
• ipfs_dispatch.scala - Transmits transactions to all nodes on the network.
• node_actor.scala - Defines node paths and how data is read at nodes.

Getting Started:

Testing the Blockchain

In the /Ozone-Blockchain Directory:

Create a Cmake file by running the command:

touch CMakeLists.txt
touch conanfile.txt

Make a Private and Public Blockchain Key:

openssl genpkey -algorithm RSA -out private_key.pem -aes256
openssl rsa -in private_key.pem -pubout -out public_key.pem

Copy and Paste your Keys into main.cpp in the Space Provided See your Keys with the following commands:

cat private_key.pem
cat public_key.pem

Note: Do NOT add changes to git with your keys in main.cpp

Make and Open a build Directory:

mkdir build

Install Dependencies Using Conan (See conanfile.txt template before installing)

conan install . --output-folder=build --build=missing -s build_type=Release

Build Project with CMake (See CMakeLists.txt template before building):

cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make

Run the Program:

./ozone
