• Register and unregister miners using PoS consensus mechanism.
• Create new blocks and sent them between the peers.

• Store blocks using name-value LevelDB database.

npm install level fs -save
node p2p.js // create two instances
cd [location]/db/[peer Id] //in another terminal
tail –f 000003.log

• Store public private key in Blockchain Wallet using using the elliptic-curve cryptography library.

npm install elliptic --save
node wallet.js
cat wallet/private_key

For implementing API_Service :

npm install express body-parser --save
node p2p.js
http://localhost:80[port]/getWallet
http://localhost:80[port]/blocks
http://localhost:80[port]/getBlock?index=0
http://localhost:80[port]/ getDBBlock?index=0
