3. Transaction fees rate is 5% will be dedcuted from your account and will be credited to miner account upon successful addition of block into network.
4. For now upon addition of 2 transaction in transaction book, everyone starts mining.

2. Above step creates blockchain network.

Getting connected to existing blockchain network
