The rapid growth of information technology in the last two decade has changed the way people to listen to music, from using conventional method to using streaming method. On demand music streaming volume has rise 56,75% on average for period 2014-2017 but the revenue of music industry only rise around 7% on the same period even when streaming method become 97% of music consumption in 2017. The imbalance between growth of streaming volume and revenue has caused mistrust between music industry and music streaming service provider. Service provider accused to manipulate streaming data that affect music industry royalty income. Manipulation threat also come from user that hack the apps to get free streaming. <br /> <br /> <br /> <br /> <br /> <br /> This final project proposing blockchain to be used on recording music streaming consumption data. Blockchain is a distributed database that store and record data into collection of blocks that tied each other through hash function, data that already recorded on the blockchain will be very hard to be tampered. Blockchain must be run by a group of peer that work together to ensure integrity of the data. Every peer will host a collection of block that called ledger and a smart contract to interact with the ledger. Smart contract is an algorithm that has been agreed by every peer so in a trusted blockchain network every peer will host an exact same smart contract. Peers on the blockchain will be hosted by service provider and the music industry, party that have interests to protect the validity of music streaming data consumption. When the data also recorded by music industry then threat also come because music industry have interests to increase streaming data that added to ledger. <br /> <br /> <br /> <br /> <br /> <br /> Testing on the blockchain network solution performed by installing malicious smart contract on one or more node that aim to prosper the node owner. This testing reveal that the system will be run normally even when music industry node become malicious, when the malicious smart contract installed at service provider node, user will not be able to stream any content and harming service provider business. There is also a case when user hack service provider’s apps to stream a content for free, the result is the user will not be able to stream anything without permission from the blockchain network. <br />
