    Details will be discussed later but on a high level, the project includes a hyperledger based blockchain. We have got a number of IoT devices that generates data. This data needs to be verified and recorded in the blockchain. Once the data is verified, the owner of the IoT device gets reward in CryptoCurrency (need to generate new). Each block will have an owner name associated and anyone with buying authority can buy the blocks. Once the block is sold - it freezes and can't be sold further to anyone (it will stay with the second owner forever) Admin - Only admin can add the new device (this is why blockchain needs to be permissioned) Admin is authorised to add or remove users CA - Provide authority to users (different level of access - Read-only/Buy generated blocks)
