This paper introduces the technology background of blockchain and three journalism-related projects-Civil, Bitpress and Matters. Blockchain was proposed by Satoshi Nakamoto in 2008 and he released Bitcoin, the first cryptocurrency based on blockchain, in 2009. Blockchain is a decentralized ledger and it contains transactions in blocks. The difficulty of modifying data avoids double spending and keeps Bitcoin stable. In 2015, another blockchain-based cryptocurrency system, Ethereum, brought the feature of smart contract into blockchain. Smart contracts can be executed without the third-party agent, so it expands the application of blockchain. Civil, Bitpress and Matters aim to build news/content distribution platforms based on cryptocurrency and develop new news recommender system to break the echo chamber. If the exchange between cryptocurrency and fiat currency is stable, it will create a sustainable ecosystem for journalism industry. Meanwhile, the tamper-proof trait of blockchain can trace origins of news to control the spread of fake news. Blockchain will be an opportunity to help journalists bring their readers/audience back and have their trust again. |
