This paper proposes a system that provides video streaming services from the Internet of Media Things using blockchain and cryptocurrency (token). The user pays the token by the contract terms of the smart contract written on the blockchain through the distributed application (DApp). The IP camera, which is paid the token, streams the taken video to the user in real-time. To investigate the possibility of a blockchain camera streaming service, we upload a smart contract for streaming service on Etherium-based blockchain, and ERC20 tokens necessary for the transaction are created and implemented. To overcome the slow trading speed and the disability of proper refunding, the off-chain transaction, one of the blockchain scaling techniques, was applied and implemented in the system.
